NOV; DINOFLAGELLATE; ULTRASTRUCTURE; MORPHOLOGY; PHYLOGENY; CINCTA; LIGHT	Two new woloszynskioid dinoflagellates, Asulcocephalium miricentonis gen. et sp. nov. and Leiocephalium pseudosanguineum gen. et sp. nov., are described from Japanese freshwater ponds on the basis of bright field and fluorescence light microscopy, scanning and transmission electron microscopy, and molecular phylogeny inferred from rDNA sequences. Asulcocephalium miricentonis has a spherical anterior nucleus and chloroplast with a pyrenoid penetrated by the cytoplasm. This species has 9-12 latitudinal series of amphiesmal vesicles (AVs), including an apparently large AV on the right ventral side of the epicone. Leiocephalium pseudosanguineum has a U-shaped nucleus in the epicone and chloroplasts without a pyrenoid. This species has at least 24 latitudinal series of AVs. The characteristic features of both species were brick-like material ( type E) in the eyespot and the lack of an apical furrow. These features coincide with those of Polarella glacialis, but the two species differ in cell shape, number and arrangement of AVs, shape of resting cysts, and habitats; i.e., P. glacialis has been reported only from marine cold waters. Molecular phylogeny revealed that A. miricentonis and L. pseudosanguineum were positioned in the Suessiaceae and closely related to Piscinoodinium sp., but their relationship to Polarella and other reported taxa was not supported.

MARINE BIOLOGY			English	Article							HARMFUL ALGAL BLOOMS; ALEXANDRIUM-CATENELLA; GUT PASSAGE; DINOFLAGELLATE CYSTS; POPULATIONS; PACIFIC; DINOPHYCEAE; TRANSPORT; SURVIVAL; OYSTERS	The diatom Nitzschia bizertensis was recently discovered in Bizerte Lagoon (Tunisia, SW Mediterranean Sea), where it was shown to produce the amnesic shellfish poisoning toxin, domoic acid (DA). This diatom was previously found to be widespread in both time and space throughout the lagoon. The present study was carried out to test the hypothesis that N. bizertensis is able to survive after being filtered and ejected as biodeposits (faeces plus pseudofaeces) by mussels. N. bizertensis cultures (strains BD4 and BD8), at natural bloom concentrations, were fed to mussels (Mytilus sp.). The stomach contents (after 1 h) and biodeposits (after 48 h) were observed for the presence and viability of N. bizertensis cells. Light microscopy revealed intact and partial cells of N. bizertensis in both the stomach contents and biodeposits of the mussels. Incubation of the biodeposits resulted in the regrowth of N. bizertensis. This provides evidence that transplanted mussels have the potential to serve as vectors for the transport of N. bizertensis. Furthermore, cells regrown from the biodeposits contained DA, but at levels lower than those in pre-filtered cells (up to 11.9 fg cell(-1)). Thus, regrown cells remain toxigenic. The results suggest that one must guard against spreading N. bizertensis and other DA producers via the transfer of shellfish from contaminated to pristine areas.

While resting cyst production and wide temperature tolerance have been well documented as two adaptive strategies for HAB-forming dinofiagellates, little attention has been paid to the molecular mechanisms, such as the functional genes and their expressions relevant to these ecological processes. Here, the cloning of the gene Hsp70, a gene putatively involved in the process of temperature stress responses, in A. sanguinea and its differential expressions in response to temperature stress and transition of life cycle stages were reported. Based on homologous cloning and the rapid amplification of cDNA ends (RACE), the full-length cDNA sequence (2171 bp) of an Hsp70 gene from A. sanguinea (AsHsp70) was obtained (Accession No. KJ755185), with an open reading frame of 1950 bp. The deduced 649 amino acids (aa) possessed an ATPase domain of 399 aa, a substrate peptide binding domain of 124 aa and a C-terminus domain of 126 aa. The highly conserved motifs of Hsp70 family identified in AsHsp70 suggest conservative function of Hsp70. Real-time quantitative PCR revealed that AsHsp70 expression (20 C-maintained) was dramatically up-regulated by both low (15 degrees C, 10 degrees C, 5 degrees C) and high (25 degrees C, 30 degrees C) temperature shocks. Rapid and significant increase of AsHsp70 expression could be detected within 10 min after exposure to lower temperature stress (10 degrees C). Compared with the stepwise increases or decreases in temperature (+/- 5 degrees C each step), one-step shocks (+/- 10 degrees C) elicited markedly higher AsHsp70 transcripts. In addition, AsHsp70 transcription varied with growth stage and life cycle, peaking in immature cysts undergoing morphogenesis and returning to lower levels in cysts when morphogenesis was completed. The results together strongly suggest that A. sanguinea is more tolerant to gradual than drastic temperature stress and that AsHsp70 may be involved in the adaptation of A. sanguinea to varying temperatures. It is also suggested that Hsp70 might play roles in the encystment of dinoflagellates, which, however, needs more solid evidence for confirmation. (C) 2015 Elsevier B.V. All rights reserved.

The aim of the present work was to characterize the influence of bacteria on the growth and function of the dinoflagellate Alexandrium tamarense. Axenic microalgal cultures were inoculated with a microbial community and the resulting cultures were monitored over a 15-month period, in order to allow for the establishment of specific algal-bacterial associations. Algal cells maintained in these new mixed cultures first experienced a period of growth inhibition. After several months, algal growth and cell volume increased, and indicators of photosynthetic function also improved. Our results suggest that community assembly processes facilitated the development of mutualistic relationships between A. tamarense cells and bacteria. These interactions had beneficial effects on the alga that may be only partly explained by mixotrophy of A. tamarense cells. The potential role of organic exudates in the establishment of these algal-bacterial associations is discussed. The present results do not support a role for algal-bacterial interactions in dinoflagellate toxin synthesis. However, variations observed in the toxin profile of A. tamarense cells during culture experiments give new clues for the understanding of biosynthetic pathways of saxitoxin, a potent phycotoxin.

J	Figueroa, RI; Dapena, C; Bravo, I; Cuadrado, A				Figueroa, Rosa I.; Dapena, Carlos; Bravo, Isabel; Cuadrado, Angeles			The Hidden Sexuality of <i>Alexandrium Minutum</i>: An Example of Overlooked Sex in Dinoflagellates	PLOS ONE			English	Article							LIFE-CYCLES; GONYAULAX-TAMARENSIS; GENUS ALEXANDRIUM; CYST FORMATION; CELL-CYCLE; DINOPHYCEAE; DNA; REPRODUCTION; ORGANIZATION; SEGREGATION	Dinoflagellates are haploid eukaryotic microalgae in which rapid proliferation causes dense blooms, with harmful health and economic effects to humans. The proliferation mode is mainly asexual, as the sexual cycle is believed to be rare and restricted to stressful environmental conditions. However, sexuality is key to explaining the recurrence of many dinoflagellate blooms because in many species the fate of the planktonic zygotes (planozygotes) is the formation of resistant cysts in the seabed (encystment). Nevertheless, recent research has shown that individually isolated planozygotes in the lab can enter other routes besides encystment, a behavior of which the relevance has not been explored at the population level. In this study, using imaging flow cytometry, cell sorting, and Fluorescence In Situ Hybridization (FISH), we followed DNA content and nuclear changes in a population of the toxic dinoflagellate Alexandrium minutum that was induced to encystment. Our results first show that planozygotes behave like a population with an "encystment-independent" division cycle, which is light-controlled and follows the same Light: Dark (L:D) pattern as the cycle governing the haploid mitosis. Resting cyst formation was the fate of just a small fraction of the planozygotes formed and was restricted to a period of strongly limited nutrient conditions. The diploid-haploid turnover between L:D cycles was consistent with two-step meiosis. However, the diel and morphological division pattern of the planozygote division also suggests mitosis, which would imply that this species is not haplontic, as previously considered, but biphasic, because individuals could undergo mitotic divisions in both the sexual (diploid) and the asexual (haploid) phases. We also report incomplete genome duplication processes. Our work calls for a reconsideration of the dogma of rare sex in dinoflagellates.

We report here on the analysis of a high-quality assembly from the 1180-megabase genome of Symbiodinium kawagutii. We annotated protein-coding genes and identified Symbiodinium-specific gene families. No whole-genome duplication was observed, but instead we found active (retro) transposition and gene family expansion, especially in processes important for successful symbiosis with corals. We also documented genes potentially governing sexual reproduction and cyst formation, novel promoter elements, and a microRNA system potentially regulating gene expression in both symbiont and coral. We found biochemical complementarity between genomes of S. kawagutii and the anthozoan Acropora, indicative of host-symbiont coevolution, providing a resource for studying the molecular basis and evolution of coral symbiosis.

Based on the unique thecal plate arrangement, this species was previously interpreted as a missing link in the evolution between the genus Protoperidinium and the Diplopsalioideae. We isolated living K. acuta cysts from the south-western Caspian Sea and the central Baltic (Finland), and re-established the cyst-theca relationship. The cysts had a distinctive polar and dorsoventral compression and a characteristic wrinkly texture. The plate formula of the thecate stage was Po, X, 4, 2a, 7, 3c+t, ?s, 5, 1. Large subunit (LSU) and small subunit (SSU) ribosomal DNA sequences obtained through single-cell PCR of these cysts reveal that this species is close to Protoperidinum excentricum which belongs to the Excentrica section of the genus Protoperidinium. We suggest that it evolved from the genus Diplopsalis through a split of the apical and anterior intercalary plates. Furthermore, that the split of the antapical plates occurred several times independently in the evolution of Protoperidinium and Diplopsalioideae and is therefore a polyphyletic trait. The cyst of Kolkwitziella is considered an indicator of low salinities, specifically between 0 and 22 psu. Geochemical analysis of the cyst walls suggests a heterotrophic mode of nutrition.

These blooms are often associated with noxious effects on humans and deaths of benthic invertebrates. Previous studies carried out on the Conero Riviera (northern Adriatic Sea) highlighted that Ostreopsis abundances recorded on rocks were significantly higher than on the surface of seaweeds, suggesting that some allelopathic interactions might occur between Ostreopsis and macroalgal substrates. In this study we investigated under experimental conditions the interactions between O. cf. ovata and three of the most common macroalgae in this area: Dictyota dichotoma (brown alga), Rhodymenia pseudopalmata (red alga) and Ulva rigida (green alga). Three different experiments were set up: O. cf. ovata was grown (i) together with fresh macroalgal tissues, (ii) in media in which macroalgae were previously cultured, and (iii) in media with the addition of dry macroalgal powder at different concentrations. The results indicated that all the investigated seaweeds exerted negative effects toward the benthic dinoflagellate O. cf. ovata. D. dichotoma inhibited the growth of O. cf. ovata in all tested experimental conditions; U. rigida had inhibitory effect both in form of fresh thalli and dry powder but not as growth medium filtrate, suggesting that either Ulva does not release any allelopathic compound in the medium in absence of O. cf. ovata or the alleged released allelochemicals are rapidly degradable. Neither the fresh thalli of R. pseudopalmata or the filtrate of its culture medium showed any inhibitory effects, while a negative effect was only observed at high concentrations of dry thallus powder. With the exception of D. dichotoma co-culture experiment, a complete algicidal effect was never observed partly because O. cf. ovata produced a large amount of resting stages, which permitted its survival.

Rapid growth and concerted sexual transitions by a bloom of the harmful dinoflagellate <i>Alexandrium fundyense</i> (Dinophyceae)	LIMNOLOGY AND OCEANOGRAPHY			English	Article							NAUSET MARSH SYSTEM; GONYAULAX-TAMARENSIS; CYST FORMATION; CELL-CYCLE; RED-TIDE; CAPE-COD; TEMPERATURE; DYNAMICS; PHYTOPLANKTON; SALINITY	Transitions between life cycle stages by the harmful dinoflagellate Alexandrium fundyense are critical for the initiation and termination of its blooms. To quantify these transitions in a single population, an Imaging FlowCytobot (IFCB), was deployed in Salt Pond (Eastham, Massachusetts), a small, tidally flushed kettle pond that hosts near annual, localized A. fundyense blooms. Machine-based image classifiers differentiating A. fundyense life cycle stages were developed and results were compared to manually corrected IFCB samples, manual microscopy-based estimates of A. fundyense abundance, previously published data describing prevalence of the parasite Amoebophrya, and a continuous culture of A. fundyense infected with Amoebophrya. In Salt Pond, a development phase of sustained vegetative division lasted approximately 3 weeks and was followed by a rapid and near complete conversion to small, gamete cells. The gametic period (approximate to 3 d) coincided with a spike in the frequency of fusing gametes (up to 5% of A. fundyense images) and was followed by a zygotic phase (approximate to 4 d) during which cell sizes returned to their normal range but cell division and diel vertical migration ceased. Cell division during bloom development was strongly phased, enabling estimation of daily rates of division, which were more than twice those predicted from batch cultures grown at similar temperatures in replete medium. Data from the Salt Pond deployment provide the first continuous record of an A. fundyense population through its complete bloom cycle and demonstrate growth and sexual induction rates much higher than are typically observed in culture.

Harmful algal blooms and climate change: Learning from the past and present to forecast the future	HARMFUL ALGAE			English	Article						Harmful algal blooms; HAB; Climate change	DOMOIC ACID PRODUCTION; PHYTOPLANKTON COMMUNITY STRUCTURE; PARALYTIC SHELLFISH TOXINS; DINOFLAGELLATE PROTOCERATIUM-RETICULATUM; NITZSCHIA SPP. BACILLARIOPHYCEAE; CO2 CONCENTRATING MECHANISMS; INORGANIC CARBON ACQUISITION; SETO INLAND SEA; PSEUDO-NITZSCHIA; MARINE-PHYTOPLANKTON	Climate change pressures will influence marine planktonic systems globally, and it is conceivable that harmful algal blooms may increase in frequency and severity. These pressures will be manifest as alterations in temperature, stratification, light, ocean acidification, precipitation-induced nutrient inputs, and grazing, but absence of fundamental knowledge of the mechanisms driving harmful algal blooms frustrates most hope of forecasting their future prevalence. Summarized here is the consensus of a recent workshop held to address what currently is known and not known about the environmental conditions that favor initiation and maintenance of harmful algal blooms. There is expectation that harmful algal bloom (HAB) geographical domains should expand in some cases, as will seasonal windows of opportunity for harmful algal blooms at higher latitudes. Nonetheless there is only basic information to speculate upon which regions or habitats HAB species may be the most resilient or susceptible. Moreover, current research strategies are not well suited to inform these fundamental linkages. There is a critical absence of tenable hypotheses for how climate pressures mechanistically affect HAB species, and the lack of uniform experimental protocols limits the quantitative cross-investigation comparisons essential to advancement. A HAB "best practices" manual would help foster more uniform research strategies and protocols, and selection of a small target list of model HAB species or isolates for study would greatly promote the accumulation of knowledge. Despite the need to focus on keystone species, more studies need to address strain variability within species, their responses under multifactorial conditions, and the retrospective analyses of long-term plankton and cyst core data; research topics that are departures from the norm. Examples of some fundamental unknowns include how larger and more frequent extreme weather events may break down natural biogeographic barriers, how stratification may enhance or diminish HAB events, how trace nutrients (metals, vitamins) influence cell toxicity, and how grazing pressures may leverage, or mitigate HAB development. There is an absence of high quality time-series data in most regions currently experiencing HAB outbreaks, and little if any data from regions expected to develop HAB events in the future. A subset of observer sites is recommended to help develop stronger linkages among global, national, and regional climate change and HAB observation programs, providing fundamental datasets for investigating global changes in the prevalence of harmful algal blooms. Forecasting changes in HAB patterns over the next few decades will depend critically upon considering harmful algal blooms within the competitive context of plankton communities, and linking these insights to ecosystem, oceanographic and climate models. From a broader perspective, the nexus of HAB science and the social sciences of harmful algal blooms is inadequate and prevents quantitative assessment of impacts of future HAB changes on human wellbeing. These and other fundamental changes in HAB research will be necessary if HAB science is to obtain compelling evidence that climate change has caused alterations in HAB distributions, prevalence or character, and to develop the theoretical, experimental, and empirical evidence explaining the mechanisms underpinning these ecological shifts.

In this study, a toxic dinoflagellate strain of A. tamarense CI01 was selected for studying the PSTs' concentration and the related protein variation during the whole cell cycle under different nutrient conditions. High-performance liquid chromatography, 2-D DIGE and Western blotting were used collectively for protein profiling and identification. Results showed that the toxin content was suppressed under nitrogen limiting condition, but enhanced in phosphorous limiting medium. Based on the results of proteomics analysis, 7 proteins were discovered to be related to the PSTs biosynthesis of A. tamarense CI01, including S-adenosylhomocysteine hydrolase, ornithine cyclodeaminase, argininosuccinate synthase, methyluridine methyltransferase cystine ABC transporter, phosphoserine phosphatase, argininosuccinate synthase and acyl-CoA dehydrogenase, which corresponds to the metabolism of the methionine, cysteine, ornithine, arginine and proline. Moreover, some photosynthesis relating proteins also increased their expression during PST synthesis period in A. tamarense CI01, such as phosphoenolpyruvate carboxylase, chloroplast phosphoglycerate kinase, peridininchlorophyll alpha-binding protein, Mg2+ transporter protein and chloroplast phosphoglycerate kinase. The above findings are in support of our hypothesis that these proteins are involved in toxin biosynthesis of A. tamarense CI01, but cause-and-effect mechanisms need to be investigated in further studies.

Our results highlight five features not described before in A. pseudogonyaulax life cycle: (i) A. pseudogonyaulax gametes showed two modes of conjugation, anisogamy and isogamy, (ii) sexual conjugation occurs either in the dark or in the light phase by engulfment or a fusion process, (iii) the presence of planozygote and newly formed cysts in monoclonal culture suggests homothallism, (iv) newly formed cysts have very dark vesicular content and are mostly unparatabulated when observed under light microscope and (v) natural resting cysts are able to give either a planomeiocyte or two vegetative cells. Cyst viability was enhanced after 5 months of cold storage (4 degrees C), with excystment rate reaching 97% after 3 d of incubation. Excystment rate was highest (43%-79%) in Enriched Natural Sea Water diluted culture medium, whereas few germling cells were able to survive without the culture medium (0%-13%). Salinity-irradiance experiments revealed that the highest cell concentrations occur at high irradiances for all the tested salinities. Vegetative growth rates generally increased with increasing irradiance, and were less dependent on salinity variations. The relatively low growth rate, low cell densities in the laboratory, and the notable capacity of producing cysts along growth phases of A. pseudogonyaulax could explain the occurrence of high resting cysts densities in the sediment of Bizerte lagoon and the relatively low abundances of vegetative cells in the water column.

The UPGMA dendrogram and FCA revealed the existence of 3 clusters. Assignment analysis suggested the occurrence of gene flows between the Japanese Pacific coast (cluster-1) and the Chinese Zhejiang coast (cluster-2). Human transportations are suspected to explain the lack of genetic difference between several pairs of distant Japanese samples, hardly explained by a natural dispersal mechanism. The genetic isolation of the population established in the Sea of Japan (cluster-3) suggested the existence of a strong ecological and geographical barrier. Along the Pacific coasts, the South North current allows limited exchanges between Chinese and Japanese populations. The relationships between Temperate Asian and Mediterranean individuals suggested different scenario of large-scale dispersal mechanisms. (C) 2015 Published by Elsevier Ltd.

We reciprocally transferred Gonyostomum semen (Raphidophyceae) cysts from three lakes into native and foreign waters originating from the respective habitats. Germination rate and germling growth were impacted by water origin, but there was no preference for native water. Gonyostomum semen's ability to germinate in different conditions might explain its expansion in northern Europe.

Until now, the biology and physiology of V. rugosum have not been fully investigated. We studied the growth characteristics and toxicity of a V. rugosum strain (IFR-VRU-01), isolated in the Ingril lagoon in June 2009 (North-Western French Mediterranean Sea). It was cultivated in Enriched Natural Sea Water (ENSW) with organic (urea) and inorganic (ammonium and nitrate) nitrogen, at a temperature of 25 degrees C and irradiance of 100 mol/m(2)s(-1). Results showed that ammonium was assimilated by cells more rapidly than nitrate and urea. V. rugosum is thus an osmotrophic species using urea. Consequently, this nitrogen form could contribute to the growth of this dinoflagellate species in the natural environment. There was no significant difference (Anova, p = 0.856) between the growth rate of V. rugosum cultivated with ammonium (0.28 +/- 0.11 day(-1)), urea (0.26 +/- 0.08 day(-1)) and nitrate (0.24 +/- 0.01 day(-1)). However, the production of chlorophyll a and pinnatoxin G was significantly lower with urea as a nitrogen source (Anova, p < 0.027), suggesting that nutritional conditions prevailing at the moment of the bloom could determine the cellular toxicity of V. rugosum and therefore the toxicity measured in contaminated mollusks. The relatively low growth rate (0.28 day(-1)) and the capacity of this species to continuously produce temporary cysts could explain why cell densities of this species in the water column are typically low (20,000 cells/L).

Overwintering of the parasitic dinoflagellate <i>Hematodinium perezi</i> in dredged blue crabs (<i>Callinectes sapidus</i>) from Wachapreague Creek, Virginia	JOURNAL OF INVERTEBRATE PATHOLOGY			English	Article						Hibernation; Life cycle; Seasonality; Infection; Parasite; Crustacea; Decapoda	LOBSTER NEPHROPS-NORVEGICUS; IN-VITRO CULTIVATION; CHIONOECETES-OPILIO; EXPERIMENTAL INFECTIONS; ORCHITOPHRYA-STELLARUM; DEVELOPMENTAL CYCLE; AMERICAN LOBSTER; CONCEPTION BAY; DISEASE; MORTALITY	Parasitic dinoflagellates in the genus Hematodinium cause disease and mortality in several commercially important marine decapod crustaceans. One species, Hematodinium perezi, occurs in blue crabs, Callinectes sapidus, along the eastern seaboard and Gulf coast of the USA. The parasite infects blue crabs, other decapods, and amphipods in the high salinity waters of coastal bays. Epizootics of the parasite often reach prevalence levels of 75-80% during outbreaks with diseased crabs dying from the infection. Prevalence of the parasite is bimodal, with a minor peak in late spring or summer, and a major peak in fall, and declining rapidly to nearly zero in late November and December. The rapid decline in infections in the late fall brings up the question of whether the parasite overwinters in crabs or whether it uses an unidentified resting stage, such as a cyst. We report observations on the prevalence of the parasite from winter dredge surveys undertaken in 2011 and 2012. Crabs were examined via hemolymph smears, histology, and PCR diagnosis for the presence of H. perezi and other pathogens. Active infections were observed from January through March in 2011 and 2012, indicating the parasite can overwinter in blue crabs. However, several crabs that were positive by PCR had presumptive effete infections that were difficult to diagnose in histological slides and hemolymph smears. These infections did not appear to be active and may have been in subsidence. Dredged crabs with light and moderate active infections were held at 15 degrees C to determine if the parasite was capable of rapid progression. In 8 cases, infections exhibited logarithmic growth progressing rapidly over 8-12 days. We present evidence that overwintering of H. perezi occurs in the blue crab hosts, that infections are capable of responding rapidly to increases in temperatures, and that overwintering provides a reservoir of infected animals for transmission to occur in the spring.

Morphological examination and ribotyping of cells obtained from a culture called ABZ1 obtained from a cyst isolated in lagoon sediment confirmed that the species was A. pacificum. The toxin profile from the ABZ1 culture harvested during exponential growth phase was simple and composed of the N-sulfocarbamoyl toxins C1 (9.82 pg toxin cell(-1)), the GTX6 (3.26 pg toxin cell(-1)) and the carbamoyl toxin Neo-STX (0.38 pg toxin cell(-1)).The latter represented only 2.8% of the total toxins in this strain. High abundance of A. pacificum cysts correlated with enhanced percentages of water and organic matter in the sediment. In addition, sediment fractions of less than 63 mu m were examined as a favorable potential seedbed for initiation of future blooms and outbreaks of A. pacificum in the lagoon. A significant difference in the cyst distribution pattern was recorded among the lagoon's different zones, with the higher cyst abundance occurring in the inner waters. Also, no correlation due to the specific hydrodynamics of the lagoon was observed in the spatial distribution of A. pacificurn cysts and vegetative cells. (C) 2015 Elsevier B.V. All rights reserved.

Along the Portuguese coast (NE Atlantic), G. catenatum shows a complex bloom pattern, raising questions about the origin and affinities of each bloom population. In this work, the variability within six cultured strains of G. catenatum isolated from Portuguese coastal waters (S coast, W coast and NW coast), between 1999 and 2011, was investigated. The strains were analyzed for toxin profiling and intra-specific genetic diversity. Regarding the toxin profile, differences recorded between strains could not be assigned to the time of isolation or geographical origin. The parameter that most influenced the toxin profile was the life-cycle stage that originated the culture: vegetative cell versus hypnozygote (resting cyst). At the genetic level, all strains showed similar sequences for the D1-D2 region of the large subunit (LSU) of the nuclear ribosomal DNA (rDNA) and shared complete identity with strains from Spain, Algeria, China and Australia. Conversely, we did not find a total identity match for the ITS-5.8S nuclear rDNA fragment. After sequence analysis, two guanine/adenine (R) single nucleotide polymorphisms (SNP 1 and 2) were detected for all strains, in the ITS1 region. This species has been reported to present very conservative LSU and ITS-5.8S rDNA regions, though with few SNP, including SNP1 of this study, already attributed to strains from certain locations. The SNP here described characterize G. catenatum populations from Portuguese waters and may represent valuable genetic markers for studies on the phylogeography of this species.

Although the species has been classified in both Peridinium and Peridiniopsis, evidence from nucleotide sequences consistently shows that its closest relatives are within the Scrippsiella group. The genus Naiadinium Carty has been recently described with P. polonicum as its type species. However, Naiadinium was separated from other peridinioids only on the basis of shape and plate arrangements and these characters do not allow reliable determination of its closest phylogenetic relatives. Serial section fine-structural analysis revealed the presence of a small peduncle supported by a conspicuous microtubular basket that extended far into the cell; a complex pusular system that included a collecting chamber from which about 70 pusular tubes radiated; a flagellar apparatus with general peridinioid characters but with an unusually large distance of nearly 700 nm between basal bodies. An ITS1-5.8S-ITS2 rDNA-based phylogenetic analysis grouped, with high statistical support, Naiadinium polonicum with three species currently placed in Scrippsiella, viz. S. irregularis, S. precaria and S. ramonii. (C) 2015 Elsevier GmbH. All rights reserved.

This dinoflagellate proliferation was dominated by Ceratium spp., but environmental conditions also favored to a lesser amount the occurrence of toxigenic dinoflagellates, such as Atexandrium tamarense and Protoceratium reticulatum, whose toxins were hardly detected in any other areas along the expedition transect of the R/V Puerto Deseado between 38 and 56 degrees S (Ushuaia-Mar del Plata) in March/April 2012. Generally vegetative cells of A. tamarense and P. reticulatum co-occurred with their respective phycotoxins in the water column and their cysts in the upper sediment layers. Two strains of A. tamarense were isolated from the bloom sample and morphologically characterized. Their PSP toxin profiles consisted of C1/2, gonyautoxins 1/4 and to a lesser amount of neosaxitoxin and confirmed earlier data from this region. The ratios between autotrophic picoplankton and heterotrophic bacteria were higher in shelf waters in the north than in Beagle-Magellan waters in the south of San Jorge Gulf. (C) 2015 Elsevier B.V.

It was used as type of Goniodoma, Heteraulacus and Yesevius, providing various sources of nomenclatural and taxonomic confusion. Particularly, several early authors emphasised that the organisms investigated by C.G. Ehrenberg and S.F.N.R. von Stein were not conspecific, but did not perform the necessary taxonomic conclusions. The holotype of P. acuminatum is an illustration dating back to 1834, which makes the determination of the species ambiguous. We collected, isolated, and cultivated Scrippsiella acuminata, comb. nov. (strain GeoB 427) from the type locality off Kiel, Germany (Baltic Sea). We barcoded the species of the Thoracosphaeraceae using rRNA sequences and investigated the morphology of the strain using light and electron microscopy. As taxonomic result, we designate an epitype for Peridinium acuminatum, as no conflict with C.G. Ehrenberg's protologue can be stated. It is indistinguishable from Scrippsiella trochoidea (likewise described from the Kiel Fjord) that we consider a later heterotypic synonym. Our study contributes to the disentanglement of dinophyte taxonomy in a very challenging case, and we trust that C.G. Ehrenberg and S.F.N.R. von Stein investigated different species under the epithet 'acuminatum'. The complex nomenclature and taxonomy of Goniodoma, and its type species Goniodoma acuminatum, is discussed in the Electronic Supplement. We consider Pyrrhotriadinium, with the type species Pyrrhotriadinium polyedricum (Gonyaulacales), well suited to harbour all gonyaulacalean taxa so far assigned to Goniodoma and Heteraulacus as well.

This non-motile cyst stage can either germinate near the sediment surface to provide the inoculum for subsequent blooms or, be buried by sediment deposits over time and entrained into the sedimentary record. Buried cysts can be resuspended into the water column by mixing events (e.g., storms) or other disturbances (e.g., dredging). It is not clear how long cysts can survive while buried in the sediments and still be capable of germinating given favorable conditions. Here, the germination success of cysts produced by the potentially toxic dinoflagellate genus Alexandrium and the non-toxic dinoflagellate genus Scrippsiella is reported from a 60-cm sediment core collected in Sequim Bay, WA, in December 2011. Cysts of Alexandrium spp. and Scrippsiella spp. were isolated from 2-cm sections of the core, placed in individual wells of a 96-well plate with growth medium, imaged, incubated at favorable conditions and monitored for germination. An image analysis program, DinoCyst, was used to quantitatively measure the amount of granular storage products, presumed energy stores, inside the cytoplasm to test the hypothesis that older cysts located deeper in the sediment core will have fewer energy stores available and will be less likely to germinate. An index of the area of the cytoplasm occupied with granular storage products relative to cyst size, termed 'cytoplasmic fullness', and age, based on Pb-210 dating of surrounding sediments, was compared with germination success or failure. This research indicates that cysts of Alexandrium spp. and Scrippsiella spp. can remain viable in sediments for 60 years or longer, show little visual evidence of cytoplasmic deterioration over this timescale (as measured by cytoplasmic fullness), and that germination success is statistically similar for cysts isolated from 0-60 cm deep in the sediment core. These results suggest that a cyst's cytoplasmic fullness is not indicative of viability and that cysts located as deep as 60 cm in the sediments are as likely to germinate as surface cysts given favorable conditions.

Potassium currents inhibition by gambierol analogs prevents human T lymphocyte activation	ARCHIVES OF TOXICOLOGY			English	Article						Gambierol; Heptacyclic analog of gambierol; Tetracyclic analog of gambierol; Voltage-gated potassium channels; Human T lymphocytes; Ciguatoxin; Autoimmune diseases	DINOFLAGELLATE GAMBIERDISCUS-TOXICUS; ION CHANNELS; BIOLOGICAL EVALUATION; AUTOIMMUNE-DISEASES; GENE-EXPRESSION; MESSENGER-RNA; UP-REGULATION; K+ CHANNELS; KV1.3; ASTHMA	Gambierol is a marine polycyclic ether toxin, produced along with ciguatoxin congeners by the dinoflagellate Gambierdiscus toxicus. We have recently reported that two truncated skeletal analogs of gambierol comprising the EFGH- and BCDEFGH-rings of the parent compound showed similar potency to gambierol on voltage-gated potassium channels (Kv) inhibition in neurons. Gambierol and its truncated analogs share the main crucial elements for biological activity, which are the C28=C29 double bond within the H-ring and the unsaturated side chain. Since Kv channels are critical for the regulation of calcium signaling, proliferation, secretion and migration in human T lymphocytes, we evaluated the activity of both the tetracyclic and heptacyclic analogs of gambierol on potassium currents in resting T lymphocyte and their effects on interleukin-2 (IL-2) release and gene expression in activated T lymphocytes. The results presented in this work clearly demonstrate that both truncated analogs of gambierol inhibit Kv channels present in resting T lymphocytes (Kv1.3) and prevented lymphocyte activation by concanavalin A. The main effects of the heptacyclic and tetracyclic analogs of gambierol in human T cells are: (1) inhibition of potassium channels in resting and concanavalin-activated T cells in the nanomolar range, (2) inhibition of IL-2 release from concanavalin-activated T cells and (3) negatively affect the expression of genes involved in cell proliferation and immune response observed in concanavalin-activated lymphocytes. These results together with the lack of toxicity in this cellular model, indicates that both analogs of gambierol have additional potential for the development of therapeutic tools in autoimmune diseases.

However, hardly any data is available for organic cyst-forming dinoflagellates while this is an ecologically important group with a unique fossil record. We performed dilute batch experiments with four harmful dinoflagellate species known for their ability to form organic cysts: Alexandrium tamarense, Scrippsiella trochoidea, Gonyaulax spinifera and Protoceratium reticulatum. Cells were grown at a range of dissolved CO2 concentrations characterizing past, modern and projected future values (similar to 5-50 mu mol L-1), representing atmospheric pCO(2) of 180, 380, 800 and 1200 mu atm. In all tested species, C-13 fractionation depends on CO2 with a slope of up to 0.17& (mu mol L)(-1). Even more consistent correlations were found between C-13 fractionation and the combined effects of particulate organic carbon quota (POC quota; pg C cell(-1)) and CO2. Carbon isotope fractionation as well as its response to CO2 is species-specific. These results may be interpreted as a first step towards a proxy for past pCO(2) based on carbon isotope ratios of fossil organic dinoflagellate cysts. However, additional culture experiments focusing on environmental variables other than pCO(2), physiological underpinning of the recorded response, testing for possible offsets in C-13 values between cells and cysts, as well as field calibration studies are required to establish a reliable proxy.

The morphology of the motile stage was similar to Gonyaulax spinifera but had a different size, overhang, displacement and reticulations. Based on the distinct morphology of the cyst and morphological differences in motile cells, we assigned S. pachydermus from Izmir Bay to the new species Gonyaulax ellegaardiae. We elucidate the phylogenetic relationship of G. ellegaardiae through large and small subunit ribosomal DNA and show that it forms a clade with other species that belong to the G. spinifera complex.

Annually recurrent blooms of this species have been observed in the coastal waters of China, particularly in the Sishili Bay, Yantai since 2004. However, limited studies have been conducted on the recurrence mechanism of A. sanguinea other than periodical monitoring of its population dynamics and associated environmental variables. Thus, to further explore the bloom and succession mechanisms of A. sanguinea in the field, we studied the effects cif major nutritional components on the growth and encystment of A. sanguinea, as well as the effects of key environmental factors on the growth of A sanguinea through a series of laboratory trials. Our results indicated that A sanguinea was able to grow well within the temperature range of 20-25 degrees C, salinity range of 20 - 30, with the maximum laboratory irradiance of 78.14 mu E m(-2) s(-1) , and was able to survive and grow in low nutrient. However, lower concentrations of nutrients (e.g., nitrate, phosphate) and higher ammonium exerted different degrees of limiting effects on the growth of A sanguinea, and induced 2.3-21.24% of vegetative cells to form resting cysts simultaneously in laboratory cultures. On the other hand, very limited or no cyst formation was observed in nutrient-replete or extremely low nutrient cultures, indicating the threshold effect of nutritional stress on the encystment of A. sanguinea.

Forty two dinoflagellate cyst morphotypes belonging to 12 genera were identified and qualified at 12 sampling points. The cyst of Gymnodinium nolleri dominated the bay and had the highest abundance in most of the stations, following Spiniferites bulloideus and Linguloclinium machaerophorum. The highest cyst concentration was recorded in the inner part of the bay. Cyst concentration ranged between 384 and 9944 cyst g(-1) dry weight of sediment in the sampling area. Sediment metal concentrations were determined. Heavy metal levels in Izmir Inner Bay were higher than the Middle and Outer Bay. L. machaerophorum, Dubridinium caperatum and Polykrikos kofoidii showed significant positive correlation with some metals (Cd, Pb, Cu, Zn) and organic carbon content. However, there was no significant correlation between dinoflagellate cyst abundance and sediment type. (C) 2015 Elsevier Ltd. All rights reserved.

Generally, the temporal trend of blooms showed the first cell appearance at the end of July/early August, the maximum abundances in late-summer at end of September/early October reaching up to 10(6) cells g(-1), fw on macrophyte samples, and the decline of the blooms at end October/early November. Calm conditions appeared to be a prerequisite for blooms. When suitable hydrodynamic conditions exist, O. cf. ovate blooms appear to be triggered by a combination of optimal temperature and available nutrients. A water temperature threshold of 25 degrees C plays a key role in the germination of O. cf. ovate cysts and therefore in bloom onset, and an N:P ratio around Redfield value is a necessary condition to allow cell proliferation. The synergy of higher temperatures and optimal N:P ratios resulted in a higher net growth rate of O. cE ovate cells. After the onset, blooms can be maintained at temperature values even below 20 degrees C and at N:P ratios that are in excess of the Redfield ratio. Once the bloom has started it may be maintained not necessarily through high growth rates, but likely through other physiological mechanisms. Bloom decline occurred when temperatures dropped below 18 degrees C. The net effect of the synergy between local hydrodynamic conditions, temperature, and N and P availability may help to explain why blooms in the northern Adriatic Sea occur differently from those in other Mediterranean regions.

P. reticulatum produces yessotoxins (YTX) - these can be accumulated in shellfish and show potent cytotoxicity, posing a risk to human health if contaminated shellfish is consumed. YTX have been reported from coastal shellfish of many localities, but until now it was unknown if they were present in the austral Southwestern Atlantic and also if local populations of P. reticulatum have the ability to produce these toxins. In this study we report the presence of YTX in plankton samples and its production in culture by two P. reticulatum strains isolated from the San Jorge Gulf (SJG). In addition, we describe the geographical distribution and seasonal abundance of this species based on data collected over the past two decades. The YTX cell quotas calculated from net hauls (similar to 10 pg cell(-1)) are in the same range as the toxin cell quotas observed in these two isolates. The phylogenetic analysis of sequences of the hypervariable region of the large subunit (LSU) 28S rDNA showed that the two clonal strains from the SJG were part of a monophyletic clade that subdivides P. reticulatum into two well-supported, divergent sub-clades. The sequences of the two strains of P. reticulaturn from the SJG fell in the same clade as the majority of sequences of P. reticulatum, which belong to a geographically widely distributed evolutionary clade. P. reticulatum was occasionally observed from about 35 degrees S in Uruguayan shelf waters up to 530 S on the Patagonian shelf and north of Tierra del Fuego, and it was present from coastal areas up to the shelf break zone. We recorded P. reticulatum in plankton samples during spring, summer and autumn but invariably in low abundance (maximum: 560 cells L-1). Viable cysts of the species in surface sediments also showed a wide geographical distribution. Together, the high total abundances and high relative numerical contribution to planktonic dinoflagellate assemblages near frontal areas, emphasize the necessity to pay attention to the dynamics of this species in areas of potential risk of harmful algal bloom development.

J	Cruz-López, R; Maske, H				Cruz-Lopez, Ricardo; Maske, Helmut			A non-amplified FISH protocol to identify simultaneously different bacterial groups attached to eukaryotic phytoplankton	JOURNAL OF APPLIED PHYCOLOGY			English	Article						Fluorescence in situ hybridization; Epiphytic bacteria; Phytoplankton cells	IN-SITU HYBRIDIZATION; OLIGONUCLEOTIDE PROBES; CYST FORMATION; EPIFLUORESCENCE MICROSCOPY; HIROSHIMA BAY; SP NOV.; DINOPHYCEAE; IDENTIFICATION; DIATOMS; GROWTH	Eukaryotic phytoplankton and bacteria form complex trophic interactions in nature and cultures. The interaction will depend on the spatial arrangement but the architecture of these arrangements has been little investigated. Here we modified a protocol to identify and localize multiple bacterial taxa attached to phytoplankton cells in culture and natural samples, including sensitive dinoflagellates. Samples were embedded in agarose and hybridized simultaneously with different probes of distinct fluorescence properties. Embedding avoided losses or damage of host cells and preserved the attached bacteria during hybridization and washing. Embedding still allowed efficient hybridization and identification of intact host cells. After fluorescence in situ hybridization of the bacteria the phytoplankton host cells, including dinoflagellates were still intact. Digital image stacks taken with a wide field epifluorescence microscope using different excitation-emission wavelength combinations allow the location of the different bacterial groups on the host cell surface and the spatial relationship of the different bacterial groups.

To gain an insight about the effect of temperature, salinity, photoperiod and nutrient levels in culture medium growth vegetative polyclonal cells of A. catenella (strain ACO90610 QUE-Q) from sediment cysts (Quellon, Chile) were cultivated. The strain was studied in different experiments by cells count using the Utermohl method, every 2 days during 56 days. Effect of salinity (15, 20, 25, 30) using as control seawater with 31 of salinity; temperature (10, 15 and 20 degrees C) photoperiod (12: 12, 16: 08 and 8: 16 L: D) and was determinated nutrients, with L1 medium at different proportions of NaNO3 and NaHPO4. The results showed that cells of A. catenella grew in all range of salinities tested, showing a greater growth rate at 30 (3788 cells mL(-1) on day 26; mu= 0.18 div d(-1)). At 20 degrees C, temperature decrease the growth rate (<1500 cells mL(-1); mu = 0.11 div d(-1)) while at 10 degrees C and 15 degrees C stimulate the growth (> 3000 cells mL(-1); mu = 0.12 div d(-1)). The culture medium without nitrates and phosphates inhibit growth rates, while L1 and L1/ 2 support growth (> 2800 cells. L-1; mu = 0.08 and 0.06 div d(-1), respectively). Different photo-period treatments have similar results (mu = 0.05, 0.07 and 0.08 div d(-1)) reaching 2000 cells mL(-1) at the end of the experiment. These results suggest that the cultured strain responded to changes in temperature, photoperiod and differ ent nutrient concentrations.

SEXUAL RESTING CYST PRODUCTION BY THE DINOFLAGELLATE <i>AKASHIWO SANGUINEA</i>: A POTENTIAL MECHANISM CONTRIBUTING TO THE UBIQUITOUS DISTRIBUTION OF A HARMFUL ALGA	JOURNAL OF PHYCOLOGY			English	Article						Akashiwo sanguinea; geographic distribution; germination; harmful algal bloom; life cycle; resting cyst	RED TIDE; GYMNODINIUM-CATENATUM; MICRORETICULATE CYST; GONYAULAX-TAMARENSIS; SURFACE SEDIMENTS; CHESAPEAKE BAY; COASTAL LAGOON; BALLAST WATER; LIFE-HISTORY; BLOOMS	The dinoflagellate Akashiwo sanguinea is a well known, cosmopolitan harmful microalga that frequently forms harmful algal blooms (HABs) in marine estuaries from temperate to tropical waters, and has posed a severe threat to fish, shellfish, and sea birds. Therefore, it is important to understand the ecology of this species, particularly the mechanisms regulating its ubiquitous geographic distribution and frequent recurrence of. To date, the mechanisms regulating distribution and recurrence of HABs by this species have been poorly understood. While resting cyst production can play a central role in the geographic expansion and initiation of HABs, studies of the life cycle of this alga, including cyst production, have been lacking. Here, we demonstrate that A. sanguinea produces sexual resting cysts homothallically. We present evidence for cell pairs in sexual mating, biflagellated planozygote formation, and cysts of different morphologies, and we describe time series for germination of cysts to germlings with two longitudinal flagella, along with studies of possible factors affecting cyst production. Phylogenetic analysis of large sub-unit rDNA sequences revealed a monophyly of this species and thus possibly a recent common ancestor for all global populations. The discovery of resting cyst production by A. sanguinea suggests its frequent recurrence of blooms and global distribution may have been facilitated by the natural and anthropogenic transport of resting cysts.

A strong positive correlation was found between species diversity and surface salinity (R-2 = 0.94; n = 7) in the Baltic Sea-Kattegat-Skagerrak system. The most pronounced decrease in dinoflagellate cyst diversity occurred between Kattegat and the Arkona basin, where the surface salinity also steeply declined. Overall, the total cyst abundance decreased along the salinity gradient. However, in the Gotland and particularly in the Northern Central basin cyst concentrations were elevated compared to the surrounding basins and the cyst community was dominated by heterotrophic cyst-producing dinoflagellate species. Possible factors behind this observation are discussed, with increased nutrient supply as the most likely primary cause. In addition, surface salinity was also confirmed to influence process length development of Operculodinium centrocarpum (R-2 = 0.86; n = 145), which was the most abundant species in this study.

Factors regulating excystment of <i>Alexandrium</i> in Puget Sound, WA, USA	HARMFUL ALGAE			English	Article						Alexandrium; Puget Sound; Excystment; Cysts; Harmful algal bloom; Red tide	RESTING CYSTS; TAMARENSE; DINOPHYCEAE; GERMINATION; CATENELLA; TEMPERATURE; WASHINGTON; DORMANCY; DARKNESS; BLOOMS	Factors regulating excystment of a toxic dinoflagellate in the genus Alexandrium were investigated in cysts from Puget Sound, Washington State, USA. Experiments were carried out in the laboratory using cysts collected from benthic seedbeds to determine if excystment is controlled by internal or environmental factors. The results suggest that the timing of germination is not tightly controlled by an endogenous clock, though there is a suggestion of a cyclical pattern. This was explored using cysts that had been stored under cold (4 degrees C), anoxic conditions in the dark and then incubated for 6 weeks at constant favorable environmental conditions. Excystment occurred during all months of the year, with variable excystment success ranging from 31-90%. When cysts were isolated directly from freshly collected sediments every month and incubated at the in situ bottom water temperature, a seasonal pattern in excystment was observed that was independent of temperature. This pattern may be consistent with secondary dormancy, an externally modulated pattern that prevents excystment during periods that are not favorable for sustained vegetative growth. However, observation over more annual cycles is required and the duration of the mandatory dormancy period of these cysts must be determined before the seasonality of germination can be fully characterized in Alexandrium from Puget Sound. Both temperature and light were found to be important environmental factors regulating excystment, with the highest rates of excystment observed for the warmest temperature treatment (20 degrees C) and in the light.

Blooms of Alexandrium minutum reach very high concentrations of vegetative cells in the water column; and when these blooms occur, large numbers of toxic cysts can be produced and deposited on sediments becoming available to benthic species. The present study investigated the potential effect of exposure to toxic cysts of A. minutum on the periwinkle Littorina littorea. Snails were exposed for nine days to pellicle cysts of toxic and non-toxic dinoflagellates, A. minutum and Heterocapsa triquetra, respectively, followed by six days of depuration while they were fed only H. triquetra. Toxin accumulation, condition index, immune and histopathological responses were analyzed. Histological alterations were also monitored in snails exposed to a harmful A. minutum bloom, which naturally occurred in the Bay of Brest. Snails exposed to toxic cysts showed abnormal behavior that seems to be toxin-induced and possibly related to muscle paralysis. Periwinkles accumulated toxins by preying on toxic cysts and accumulation appeared dependent on the time of exposure, increasing during intoxication period but tending to stabilize during depuration period. Toxic exposure also seemed to negatively affect hemocyte viability and functions, as ROS production and phagocytosis. Histological analyses revealed that toxic exposure induced damages on digestive organs of snails, both in laboratory and natural systems. This study demonstrates that an exposure to the toxic dinoflagellate A. minutum leads to sublethal effects on L. littorea, which may alter individual fitness and increase the susceptibility of snails to pathogens and diseases.

J	Green, L; Fong, P				Green, Lauri; Fong, Peggy			A small-scale test of the species-energy hypothesis in a southern California estuary	JOURNAL OF EXPERIMENTAL MARINE BIOLOGY AND ECOLOGY			English	Article						Diversity; Infauna; Macroalgae; Microphytobenthos; Productivity; Species-energy hypothesis	GREEN ALGAL MATS; SALT-MARSH; NUTRIENT ENRICHMENT; ENTEROMORPHA-INTESTINALIS; COMPLEX INTERACTIONS; COMMUNITY RESPONSES; MACROALGAL DETRITUS; TEMPORAL-CHANGES; COASTAL WATERS; DIVERSITY	Theoretical predictions of a direct positive association between productivity and diversity (P/D) have received considerable empirical support in marine systems, although this relationship tends to break down at smaller scales (<25 km). Another theory commonly advanced in terrestrial systems, the species-energy hypothesis (SEH), relates productivity (=energy) to diversity indirectly through an increase in population abundances, which then reduces the likelihood of localized extinction and therefore enhances richness. The SEH has been supported on both global and local scales but has not been experimentally tested in estuarine systems or at the scale of a patch. We tested whether the predictions of the SEH (increased abundance and diversity) or the P/D hypothesis (increased diversity, no predictions for abundance) described the relationship between macroalgal productivity and the abundance and diversity of infauna and site-attached epifauna (hereafter macrofauna) and the microphytobenthos (MPB) in an estuarine benthic community. We conducted a single-factor experiment comparing the effects over time of three treatments comprised of two levels of macroalgae as an added energy source and a plastic mimic as a control that provided structure and habitat but no energy. Contrary to predictions of both the SEH and the P/D hypothesis, there were no measurable differences in taxonomic richness among treatments. However, in partial support of the SEH, we found that total macrofaunal abundance was 50% higher in both macroalgal treatments compared to the mimic and these were largely comprised of detritivores such as spionid polychaetes and oligochaetes. Phaeopigments increased in macroalgal plots but not the mimic, suggesting that added productivity decomposed, supplying more food for detritivores. As this taxonomic group is present in all plots, although in differing abundances, increasing energy flow through this pathway did not enhance taxonomic richness. Macroalgae stimulated the MPB (measured as chl a) more than did the mimic, and elevated chl b in macroalgal treatments indicated the increase was due to sporeling green macroalgae. However, benthic diatoms and dinoflagellates (estimated from chl c) were not affected by treatment. Thus, we found that at the patch level, neither the SEH nor the P/D hypothesis predicted patterns of diversity for estuarine macrofauna; rather, in this system, increased productivity simply supported higher abundances within the same taxonomic groups that occurred at all productivity levels.

Evidence for the existence of resting cysts of C. polykrikoides is based on the morphological and molecular phylogenetic data of the germinated cells and a resting cyst. The morphology of the resting cysts differed from that reported previously in sediments and culture experiments. The distinct feature is that the cyst body was covered by the reticulate ornaments and spines.

Gambierol, the heptacyclic analog, and the tetracyclic analog inhibited the potassium current evoked by a step pulse from -80 mV to 40 mV. The IC50 values for the three compounds were 0.75 +/- 0.15 nM, 7.6 +/- 1.2 nM, and 28 +/- 4.0 nM (the mean +/- SEM, n = 3), respectively. The cytotoxic activity was examined in order to assess a relationship between cytotoxicity and inhibition of the hKv1.2. The IC50 values for gambierol, the heptacyclic analog, and the tetracyclic analog in the wild-type CHO cells were 95 +/- 7.1 lM, 6.5 +/- 0.8 lM(the mean +/- SEM, n = 3), and > 100 lM (n = 3), respectively, whereas those in the CHO cells stably expressing hKv1.2 were 78 +/- 5.8 lM, 6.0 +/- 1.0 lM (the mean +/- SEM, n = 3), and > 100 lM (n = 3). These results suggested that cytotoxicity is not triggered by inhibition of the human Kv1.2. The electrophysiological recording at the resting potential in the presence of gambierol, the heptacyclic analog, and the tetracyclic analog revealed the dose-dependent leak current, which was largest when the heptacyclic analog was administered to the cells. We thus propose that the leak current induced by these compounds might cause a fatal effect on the cultured cells. (C) 2014 Elsevier Ltd. All rights reserved.

J	Peczula, W; Suchora, M; Zukowska, G				Peczula, Wojciech; Suchora, Magdalena; Zukowska, Grazyna			The influence of glucose and peat extract additions on the spring recruitment of <i>Gonyostomum semen</i> from the sediments	HYDROBIOLOGIA			English	Article						Gonyostomum semen; Dissolved organic carbon; Recruitment; Cyst germination; Lake sediments	DISSOLVED ORGANIC-CARBON; CLIMATE-CHANGE; TOXIC DINOFLAGELLATE; HUMIC SUBSTANCES; MASS DEVELOPMENT; RESTING CYSTS; FOREST LAKES; GERMINATION; GROWTH; PHYTOPLANKTON	The effect of two various forms of DOC on the Gonyostomum semen recruitment from sediments was conducted under experimental laboratory conditions. We tested the hypothesis that DOC is a factor enhancing spring recruitment of the species by exposing sediments from a humic lake with a 17-year bloom history, to three various DOC additions (two solutions of glucose and one solution of a peat extract). Sediments and lake water were incubated for 14 days at 16A degrees C, in 14:10 h light:dark cycle, with germling and adult cell abundance ascertained in the water every third day, and water parameters every seventh day. Our important findings were that (1) Gonyostomum recruitment was uneven and the period of germination was relatively short; (2) all treatments significantly affected germling occurrence; however, sugar-derived DOC seemed to suppress the recruitment, whereas peat extract improved it. Due to the additional phosphorus load in peat treatment (against phosphorus-free sugar treatments), it is likely that it played a major role in the observed differences, however, our results did not exclude the potential role of peat-derived DOC forms. In conclusion, we proposed that Gonyostomum expansion is supported by enhanced recruitment from sediment seed banks related to water chemistry alterations, driven by the climate change.

Eight surface sediment samples were collected to analysis of the spatial distribution of dinoflagellate cysts from two industrially polluted areas: Aliaga and Nemrut Bay (Eastern Mediterranean). A total of 42 dinoflagellate cyst morphotype were identified and total cyst abundance ranged between 11 and 2543 cyst g(-1) dry weight sediment at sampling points. The cyst assemblages were represented by cyst of Gymnodinium nolleri, Alexandrium affine type and Lingulodiniumma chaerophorum. The higher cyst concentration was recorded at mostly Aliaga Bay stations however the higher cyst diversity was found at Nemrut Bay stations. Total cyst concentration and autotrophic cyst concentration indicated metal pollution in the sampling areas whereas total number of cysts had no correlation with any metal levels in the sediment except Cr.

Here we report a new Peridiniopsis species isolated from the Jiulong River, China, which was described as jiulongensis H. Gu sp. nov. Vegetative cells of P. jiulongensis were subjected to detailed examination by light microscopy, scanning electron microscopy and transmission electron microscopy. P. jiulongensis has a plate pattern of Po, X, 3', la, 6 '', 5C, 5S, 5''',, 2 '''' and harbors a dinokaryotic and a eukaryotic nucleus. The eyespot of P. jiulongensis was bounded by triple envelopes and thus classified as type D. Molecular phylogeny based on dinoflagellate small subunit ribosomal DNA (SSU rDNA) sequences revealed that dinoflagellates with a diatom endosymbiont were monophyletic and P. jiulongensis was grouped together with Peridiniopsis cf. kevei, P niei and P. penardii. Molecular phylogeny based on endosymbiont SSU rDNA sequences showed that P. jiulongensis, P. cf. kevei, and P. penardii formed a well resolved group and were close to Thalassiosira species.

In this study, we re-examined the motile stage of B. majusculum via thecal plate analysis together with a molecular phylogenetic analysis based on partial large-subunit ribosomal DNA gene sequences. The morphological features of motile cells germinated from B. majusculum were identical to those of Pr. sinuosum, and the molecular phylogenetic analysis showed that the germinated cells and B. majusculum are closely related to Pr. pentagonum and Pr. latissimum as a sister group. Additionally, high sequence divergences were observed between the germinated cells and B. majusculum as well as Pr. pentagonum and Pr. latissimum (18.0-19.5% according to P-values and 20.7-22.9% according to Kimura two-parameter values). On the basis of these results, our study indicates that B. majusculum should be accepted as the cyst of Pr. sinuosum.

Transport of harmful marine microalgae via ship's ballast water: Management and mitigation with special reference to the Arabian Gulf region	AQUATIC ECOSYSTEM HEALTH & MANAGEMENT			English	Article; Proceedings Paper	International Conference on Marine Invasive Species: Management of Ballast Water and Other Vectors	FEB 17-19, 2014	Muscat, OMAN			ballast water management; Alexandrium; Cochlodinium; Noctiluca; ballast water exchange; ballast water heat treatment	ALEXANDRIUM-CATENELLA; DINOPHYCEAE; DISPERSAL; DIATOM; TIME; BACILLARIOPHYCEAE; ORGANISMS; TAXONOMY; PACIFIC; COMPLEX	The potential for transport of non-indigenous marine microalgae via ship's ballast water has been amply demonstrated, and nearly all known harmful algal bloom species have been documented in viable form from ship's ballast water. Ballast water uptake needs to be strongly discouraged during harmful algal bloom events. Efficacy of ballast water exchange in removing harmful microalgal cells is limited, since this nearly always leaves behind a viable inoculum. The precise location of ballast water exchange needs to be carefully chosen, and retention of dinoflagellate cysts and diatom spores in ballast tank sediments is of special concern. The only fully effective ballast water treatment for microalgae is the application of biocides, but heat treatment also offers considerable promise especially in subtropical and tropical waters. To manage harmful algal blooms, other key environmental drivers such as eutrophication and climate change also need to be addressed. Effective monitoring for harmful algal species and their toxins remains the critical tool to protect human health, fisheries, aquaculture and desalination industries. Challenges and opportunities for ballast water management in the Arabian Gulf region are discussed.

Here we established the cyst-theca relationships of 11 species (Boreadinium breve, Diplopelta globula, Diplopsalis lenticula, Diplopsalopsis ovata, Lebouraia pusilla, Niea acanthocysta, Niea chinensis, Niea torta, Oblea rotunda, Preperidinium cf. meunieri and Qia lebouriae) belonging to nine genera by incubating cysts collected along the coast of China. In addition, we obtained 22 large-subunit ribosomal DNA sequences from the germinated motile cells of these 11 species by single-cell polymerase chain reaction. A new genus, Niea, was erected to encompass species with a plate formula identical to that of Oblea, that is, Po, X, 3', 1a, 6 '', 3C+t, 5''', 2'''', but with an ortho 1'. Niea chinensis was described based on both theca and cyst morphology. The genus Oblea was emended to incorporate only species with a meta 1'. As a consequence, Oblea acanthocysta and O. torta were transferred to the newly erected genus Niea. A second new genus, Qia, was established to encompass Diplopsalis lebouriae, and the genus Diplopsalis was emended, differing from Qia in the shape of the anterior intercalary (1a) plate. Phylogenetic analyses were carried out using maximum likelihood and Bayesian inference. Molecular phylogeny revealed that the diplopsalioideans were not monophyletic and were subdivided into three clades. From our results, the shape of the first apical and anterior intercalary plates and the number of apical, anterior intercalary and antapical plates were useful characteristics to distinguish the diplopsalioideans at the genus level.

NOV; ULTRASTRUCTURE; SCRIPPSIELLA; MODELS; CYSTS; SEA	The genus Tovellia contains approximately eight described species. A new species, Tovellia paldangensis sp. nov. was observed by incubation of a cyst from sediment collected in the Paldang Dam Lake in Korea. The vegetative cells of this new species were 20.0-27.0 mu m long, 18.0-23.0 mu m wide, and 17.0-20.5 mu m thick. The cingulum was displaced by one cingulum width, the nucleus was located in the posterior part of the cell, and the chloroplasts were numerous and in yellow-green in color. A prominent red body was present on each side of the cingulum. The amphiesma had numerous thin polygonal plates that were arranged in three to four latitudinal series on the epicone and in two to three series on the hypocone. A narrow apical line of plates (ALP) extended over the anterior part of the cell, approximately in a 3/4 of the ventral side and 1/4 of the dorsal side of the epicone. The antapical plate was usually hexagonal. T. paldangensis was clearly differentiated from the other species of Tovellia by the morphology of its vegetative cell (two red bodies, and the ALP lines on each side separated by a row of four to five elongate plates) and the resting cyst (typically covered with numerous short solid spines). Phylogenetic analysis based on partial large subunit ribosomal RNA gene sequences indicated that T. paldangensis was most closely related to T. coronata, T. sanguinea, and T. aveirensis.

The present study focused on the identification of resting-stage algae from freshwater sediments in Paldang Dam Lake, an important source of water for South Korea. We examined the morphological characteristics of resting-stage specimens and identified them by germination experiments or DNA analysis. Surface sediment samples were collected from 12 sites in Paldang Dam Lake from July 2009 to June 2010. Thirty-five resting stage morphotypes were identified: 19 chlorophytes, 6 dinoflagellates, 5 diatoms, 2 cyanobacteria, 2 euglenoids and 1 cryptophyte. Resting-stage and vegetative cells of five chlorophyte morphotypes could not be identified by morphology. These specimens were identified by molecular sequence analysis based on the nuclear-encoded SSU rDNA sequences of Polyedriopsis, Oogamochlamys and Chlamydomonas. Our samples included resting-stage of the potentially toxic species Cylindrospennum stagnale, the first recorded sighting in Korea. Resting-stage assemblages were dominated by diatoms, which ranged from 560 to 2750 cells g(-1). Resting-stage of diatoms and cyanobacteria were abundant along the eastern shore toward the southern part of Paldang Dam Lake, where there have been periodic algal blooms.

We examined the cyst-theca relationships of seven Protoperidinium species isolated from sediments along the Chinese coast. Ten partial nuclear-encoded large subunit ribosomal DNA (LSU rDNA) sequences were obtained by single-cell polymerase chain reaction (PCR) for seven species belonging to the Conica and Tabulata sections of the genus. New cyst-theca relationships were established for Protoperidinium biconicum and Protoperidinium humile, and the former was restricted to warmer waters. Brigantedinium majusculum was identified as the cyst of Protoperidinium pentagonum; whereas, Trinovantedinium applanatum corresponded to Protoperidinium shanghaiense sp. nov. Phylogenetic analyses based on LSU rDNA sequences were carried out using maximum likelihood and Bayesian inference and revealed that the theca-based section Conica was polyphyletic, and Tabulata was monophyletic. Surprisingly, some cyst-based genera (e.g. Brigantedinium, Selenopemphix) proved to be polyphyletic.

The resting cysts of P. jinhaense were spherical or ovoidal, with a large reddish pigment body and a thick wall covered by numerous needle-shaped calcareous crystals. The size, shape and plate tabulation of motile cells that germinated from the resting cysts were similar to those of Pentapharsodinium tyrrhenicum and Ensiculifera carinata; however, the motile cells had a spine located in the anterior sulcal plate and many pores and spines on the thecal surface. Molecular phylogenetic analysis using internal transcribed spacer and 5.8s rDNA showed that P. jinhaense was closely related to P. tyrrhenicum. Large subunit ribosomal DNA sequences also revealed that P. jinhaense was nested within Pentapharsodinium and formed a strongly supported clade with Pentapharsodinium dalei and P. tyrrhenicum.

Coupling planktonic and benthic shifts during a bloom of <i>Alexandrium catenella</i> in southern Chile: Implications for bloom dynamics and recurrence	HARMFUL ALGAE			English	Article						Alexandrium catenella; Dinoflagellate cysts; Resting cysts; Bloom encystment/excystment; Chilean Inland Sea	HARMFUL ALGAL BLOOMS; RECENT MARINE-SEDIMENTS; DINOFLAGELLATE SCRIPPSIELLA-HANGOEI; RESTING CYSTS; SURFACE SEDIMENTS; FUNDYENSE POPULATIONS; ENVIRONMENTAL-FACTORS; SPATIAL-DISTRIBUTION; DINOPHYCEAE; GULF	Cell abundances and distributions of Alexandrium catenella resting cysts in recent sediments were studied along time at two locations in the Chilean Inland Sea exposed to different oceanographic conditions: Low Bay, which is much more open to the ocean than the more interior and protected Ovalada Island. The bloom began in interior areas but maximum cyst concentrations were recorded in locations more open to the ocean, at the end of the Moraleda channel. Our results showed a time lapse of around 3 months from the bloom peak (planktonic population) until the number of resting cysts in the sediments reached a maximum. Three months later, less than 10% of the A. catenella cysts remained in the sediments. Maximum cyst numbers in the water column occurred one month after the planktonic peak, when no cells were present. The dinoflagellate assemblage at both study sites was dominated by heterotrophic cysts, except during the A. catenella bloom. CCA analyses of species composition and environmental factors indicated that the frequency of A. catenella blooms was associated with low temperatures, but not with salinity, chlorophyll a concentration, and predator presence (measured as clam biomass). However, resting cyst distribution was only related to cell abundance and location. The occurrence of A. catenella cysts was also associated with that of cysts from the toxic species Protoceratium reticulatum. By shedding light on the ecological requirements of A. catenella blooms, our observations support the relevance of encystment as a mechanism of bloom termination and show a very fast depletion of cysts from the sediments (<3 months), which suggest a small role for resting cyst deposits in the recurrence of A. catenella blooms in this area.

High resolution sedimentary record of dinoflagellate cysts reflects decadal variability and 20th century warming in the Santa Barbara Basin	QUATERNARY SCIENCE REVIEWS			English	Article						California Current System; Last century warming; Pacific Decadal Oscillation; El Nino-Southern Oscillation; Upwelling; Primary productivity; Lingulodinium machaerophorum; Laminated sediments	CALIFORNIA CURRENT SYSTEM; SEA-SURFACE TEMPERATURE; NORTH PACIFIC; EL-NINO; SOUTHERN CALIFORNIA; CLIMATE VARIABILITY; HYDROGRAPHIC CONDITIONS; HIGH-LATITUDES; SP NOV.; OCEAN	We present a continuous record of dinoflagellate cysts from a core of laminated sediments collected in the Santa Barbara Basin (SBB), off Southern California. The core spans the last similar to 260 years and is analysed at biennial (two-year) resolution. Variations in dinoflagellate cyst assemblages are compared with 20th century historical changes, and are used to examine changes in primary productivity and species composition, which are bound to the variability in upwelling and sea-surface temperature (SST) in the region. Cysts produced by heterotrophic dinoflagellates dominate the assemblages. In particular, Brigantedinium spp. (on average 64.2% of the assemblages) are commonly associated with high levels of primary productivity, typically observed under active upwelling conditions, when nutrient supply is higher. Other heterotrophic taxa such as cysts of Protoperidinium americanum, Protoperidinium fukuyoi, Protoperidinium minutum and Archaeperidinium saanichi, all Echinidinium species, Quinquecuspis concreta and Selenopemphix undulata are more abundant in the early part of the record (similar to 1750s-1870s). These taxa are generally associated with high primary productivity and are observed predominantly during intervals marked by relatively variable conditions of SST, stratification and nutrient loading. The 20th century is marked by an increase in several species of autotrophic affinity, primarily Lingulodinium machaerophorum and Spiniferites ramosus. In recent surface sediments from the region, these species are more abundant in the Southern California Bight, and they are associated with conditions of relaxed upwelling in the SBB (typically observed during summer and fall), when SST is higher and nutrient supply is moderate. Their increasing concentrations since the early 20th century reflect warmer SST and possibly stronger stratification during the warmest season. Taken together, the changes in cyst assemblages provide further evidence that persistently warmer conditions in the SBB began affecting marine populations by the late 1920s. Decadal-scale variations in primary productivity are encoded in the heterotrophic dinoflagellate cyst record, with higher (lower) concentrations of heterotrophic taxa occurring during "cool" ("warm") phases of the Pacific Decadal Oscillation (PDO) index. Wavelet analysis of heterotrophic taxa concentrations suggests a weaker influence of the PDO on biota of the region during the 19th century. (C) 2014 Elsevier Ltd. All rights reserved.

Apoptosis of hemocytes from lions-paw scallop <i>Nodipecten subnodosus</i> induced with paralyzing shellfish poison from <i>Gymnodinium catenatum</i>	IMMUNOBIOLOGY			English	Article						Apoptosis; Gonyautoxin 2/3 epimers (GTX 2/3 epimers); Gymnodinium catenatum; Hemocyte; Nodipecten subnodosus; Paralyzing shellfish poisons	INHIBITOR OKADAIC ACID; MUSSEL MYTILUS-EDULIS; ALEXANDRIUM-FUNDYENSE; CRASSOSTREA-VIRGINICA; INDIVIDUAL CELLS; EASTERN OYSTERS; DINOFLAGELLATE; EXPOSURE; HISTOPATHOLOGY; MAINTENANCE	The toxic dinoflagellate Gymnodinium catenatum produces paralyzing shellfish poisons (PSPs) that are consumed and accumulated by bivalves. Previously, we recorded a decrease in hemocytes 24 h after injection of PSPs (gonyautoxin 2/3 epimers, GTX2/3) in the adductor muscle in the lions-paw scallop Nodipecten subnodosus. In this work, qualitative and quantitative analyses, in in vivo and in vitro experiments, revealed that the lower count of hemocytes results from cells undergoing typical apoptosis when exposed to GTX 2/3 epimers. This includes visible morphological alterations of the cytoplasmic membrane, damage to the nuclear membrane, condensation of chromatin, DNA fragmentation, and release of DNA fragments into the cytoplasm. Induction of apoptosis was accompanied by phosphatidylserine exposure to the outer cell membrane and activation of cysteine-aspartic proteases, caspase 3 and caspase 8. Addition of an inhibitor of caspase to the medium suppressed activation in hemocytes exposed to the toxins, suggesting that cell death was induced by a caspase-dependent apoptotic pathway. The results are important for future investigation of the scallop's immune system and should provide new insights into apoptotic processes in immune cells of scallops exposed to PSPs.

Modified clay (in concentration of 0, 0.1, 0.5, and 1.0 g/L) were added to cultures, and observations were made on cysts of S. trochoidea under controlled laboratory conditions. Results indicate that the removal rate of algal cells reached 97.7% at the clay concentration of 1.0 g/L. The cyst formation rate increased from 4.6% to 24.6% when the concentration of clay was increased from 0 to 1.0 g/L. Two cyst metamorphs were observed: spinal calcareous cysts and smooth noncalcareous ones. The proportion of the spinal cysts decreased from 76.9% to 24.1% when clay concentration increased from 0 to 1.0 g/L. In addition, modified clay affected cyst germination. The germination rate decreased with the increases in the clay concentrations. Non-calcareous cysts had a lower germination rate with a longer germination time. We conclude that modified clay could depress algal cell multiplication and promote formation of temporal cysts of S. trochoidea, which may help in controlling HAB outbreaks.

In the present study, we investigated the effects of nitrate and ammonium on the growth and encystment of S. trochoidea. We incubated S. trochoidea in modified f/2 media without nitrogen and silicate in flasks. The flasks were divided into two groups. Nitrate was added as a nitrogen source in the first group, and ammonium was added in the second group. The concentrations of the nitrogen compounds were 0, 10, 30, 60, and 90 mu mol/L. The results indicate that NO3 (-)-N favors cell growth, and the cultures with a higher concentration of NO3 (-)-N were ineffective at forming cysts. In contrast, NH4 (+)-N promoted cell growth and cyst formation. At similar concentrations as NO3 (-)-N, NH4 (+)-N had a toxic effect on cell growth and increased the cyst formation ratio. Thus, the NH4 (+)-N concentration is an important factor for controlling encystment. We believe that the impact of NH4 (+)-N in inducing cyst formation may be a useful feedback mechanism in ecological systems.

The new species differs in morphology and nuclear-encoded LSU rDNA and ITS sequences from B. dodgei and B. tenuissima, the two species presently comprising the genus Borghiella. Unusual features of the new species were observed particularly during asexual reproduction, which took place in the motile stage - as in many other dinoflagellates - or in a so-called division cyst, recalling cell division in the family Tovelliaceae. Such diversity in cell division is rarely reported in dinoflagellates. Morphologically Borghiella andersenii differs from B. tenuissima in being only slightly compressed dorsoventrally whereas the latter species is flat. The slight compression is also visible in lateral view. Borghiella andersenii and B. dodgei are more challenging to discriminate but the apical structure complex is only half the length in B. andersenii compared with B. dodgei (3-4 vs 6 mu m). This difference can only be accounted for in the scanning electron microscope. At the light microscopy level the epicone in B. andersenii is rounded whereas it is conical in B. dodgei. Sexual reproduction in Borghiella andersenii was homothallic by formation of planozygotes, followed by apparent resting cysts. Phylogenetic studies on woloszynskioids have recently shown that they comprise a polyphyletic assemblage, which has been divided into the three families Borghiellaceae, Tovelliaceae and Suessiaceae. New species of the three families are now being found rapidly in many parts of the world, proving that the techniques required to investigate these small, morphologically similar dinoflagellates are now in place and proving that such 'gymnodinioids' or 'woloszynskioids' comprise an often overlooked biological entity in both marine and freshwater biotopes. Based on LSU rDNA, B. andersenii is most closely related to B. tenuissima.

Previously, the name Scrippsiella trochoidea has been taxonomically clarified, leaving a reliable determination of morphologically similar, but only distantly related species impossible. We isolated and cultivated Scrippsiella erinaceus comb. nov. (strains GeoM*533 and GeoM*534) from material collected near the type locality off Rovinj, Republic of Croatia (Adriatic Sea). We barcoded the species of the Thoracosphaeraceae using rRNA sequences (including 22 new sequences) and investigated the morphology of the strains using light and electron microscopy. The Scrippsiella trochoidea species complex was composed of three primary clades, and the Adriatic strains were reliably assigned to one of them being distinct from the true Scrippsiella trochoidea. We designate an epitype for the basionym Rhabdosphaera erinaceus prepared from the strain GeoM*534. The unambiguous links between a scientific species name, its protologue, genetic characterization and spatial distribution have particular importance for character-poor, unicellular organisms such as the Dinophyceae.

Identification of the harmful dinoflagellate <i>Vulcanodinium rugosum</i> recovered from a ballast tank of a globally traveled ship in Port Tampa Bay, Florida, USA	HARMFUL ALGAE			English	Article						Vulcanodinium rugosum; Ballast water; Pinnatoxin; Portimine	ALEXANDRIUM DINOPHYCEAE; GYMNODINIUM-CATENATUM; PINNATOXIN G; MARINE; TRANSPORT; COMPLEX; MUSSELS; WATER; DIVERSITY; INFERENCE	The transport of microalgae in the ballast tanks of shipping vessels is of global concern because many algal species can survive in ballast tanks as nonmotile or cyst stages increasing the likelihood of introductions into foreign ports. In 2004 a peridinoid dinoflagellate was collected and isolated from ballast residuals of the merchant vessel Southern Fighter in Port Tampa Bay, Florida, USA. Light and electron microscopy of the motile and nonmotile peridinoid cells indicated the dinoflagellate was Vulcanodinium rugosum. Bayesian and maximum-parsimony (MP) phylogenetic analyses of V. rugosum strain CCFWC516 showed that sequenced regions of its LSU and ITS matched those of V. rugosum strains from Japan but were divergent from those strains from New Zealand and France. LC-MS analyses indicated that strain CCFWC516 did not produce the neurotoxin pinnatoxin, an ability that has been reported for other strains of this species. Analyses did show, however, that strain CCFWC516 did produce portimine, a cyclic imine produced by all other strains of this species. The M/V Southern Fighter visited numerous ports along the coast of Japan and the North Sea before sailing to Florida. The phylogenetic match to Japanese strains, as well as the ship's ballast exchange history, suggests that strain CCFWC516 originated from Japan. In light of the increase in global shipping traffic, increases in vessel size and capacity, and the increased connectivity between the Pacific Ocean and the Caribbean and Gulf of Mexico that will result from the widening of the Panama Canal, the introduction of nonnative, harmful algal species is an area of heightened concern and calls for increased vigilance.

We studied the intra-population variability of its allelochemical potency and the responses of co-occurring and potentially competing dinoflagellates to the allelochemicals. The lytic activity of 10 northern Baltic A. ostenfeldii strains was evaluated by their EC50 values (i.e. the cell concentration yielding a 50% decline in cryptophyte density), which were found to vary between 236 and 1726 cells ml(-1). When co-occurring dinoflagellates (Kryptoperidinium foliaceum, Levanderina fissa and Heterocapsa triquetra) were exposed to filtrate of A. ostenfeldii, short-term (<1 h) responses of the target species after an initial immobilization were species-specific. Almost all of the K. foliaceum cells formed cysts, L. fissa cells lost their cell shape and lysed, whereas H. triquetra cells shed their thecae. After 24 h, K. foliaceum had returned into vegetative cells and the number of immotile L. fissa and H. triquetra cells had significantly decreased. The results indicate that A. ostenfeldii can disturb the growth of competing dinoflagellates by excreting allelochemicals at bloom concentrations and that co-occurring species may develop efficient means to escape and recover from the allelochemicals, allowing them to coexist with A. ostenfeldii.

The effects of temperature and salinity on the growth of A. insuetum were also investigated. The resting cysts are characterized by a spherical shape, a small size (20-25 mu m) and the presence of either three or four red accumulation bodies. The similarity of morphological features of the resting cysts to those of other species of the minutum group (consisting of Alexandrium minutum and A. tamutum) indicates that the morphological features of resting cysts might improve the accuracy of the grouping of Alexandrium species. A. insuetum germinated from the resting cysts is morphologically consistent with vegetative cells reported from Korean and Japanese coastal areas, and has an partial large subunit (LSU) rDNA sequence identical to that from Japanese strains. The growth of A. insuetum was observed between salinity 20 and 35, with increasing temperature; however at 25 degrees C, A. insuetum could grow even at the salinity of 15. The highest growth rate (0.60 d(-1)) was observed at 25 degrees C and the salinity of 25, which is higher than the previously reported growth rate of A. tamarense, which is responsible for outbreaks of paralytic shellfish poisoining and blooms in Jinhae-Masan Bay.

The tsunami also reached Funka Bay in northern Japan and caused serious damage to the scallop cultures there, and this tsunami was believed to have affected the coastal environments in the bay. Therefore, we investigated the changes in the spatial abundance and distribution of the toxic dinofiagellates Alexandrium tamarense cysts before the tsunami (August 2010) and after the tsunami (May 2011, August 2011, May 2012 and August 2012) in the bay. Further, monthly sampling was conducted after the tsunami to identify seasonal changes of Alexandrium catenella/tamarense cysts and vegetative cells. Significant increases were observed in the populations of A. catenella/tamarense cysts, comparing the abundances before the tsunami (in August 2010; 70 +/- 61 cysts g(-1) wet sediment) to those just after it (in May 2011; 108 +/- 84 cysts g(-1) wet sediment), and both A. tamarense bloom (a maximum density was 1.3 x 10(3) cells L-1) and PSP (Paralytic Shellfish Poisoning) toxin contamination of scallops (9.4 mouse unit g(-1) was recorded) occurred in the bay. Seasonal sampling also revealed that the encystment of A. tamarense and the supply of the cysts to bottom sediments did not occur in the bay from September to April. These results strongly suggested that the mixing of the bottom sediments by the tsunami caused the accumulation of the toxic A. tamarense cysts in the surface of bottom sediment through the process of redeposition in Funka Bay. Moreover, this cyst deposition may have contributed to the toxic bloom formation as a seed population in the spring of 2011. (C) 2014 Elsevier B.V. All rights reserved.

The in situ germination flux (cells m(-2) day(-1)) was measured using 'plankton emergence trap/chambers (PET chambers)'. Germination of the cysts in the sediments occurred continuously during the study, ranging from 52 to 1753 cells m(-2) day(-1), with no temporal trend. This germination pattern appeared to be promoted by a short mandatory dormancy period for newly formed cysts coupled with a broad temperature window for germination. For the vegetative populations, high abundances (>10(5) cells m(-2)) were recorded in the water column from spring to summer and from autumn to early winter. The size of the vegetative populations did not correlate with the cyst germination flux but rather larger vegetative populations were often observed when the water temperature was around 20 degrees C, indicating that bloom development was mainly regulated by the temperature. Nonetheless, the continuous germination pattern of A. catenella is advantageous enabling the germinated cells to immediately exploit favorable bloom conditions.

Bacterial Community Affects Toxin Production by <i>Gymnodinium</i> <i>catenatum</i>	PLOS ONE			English	Article							PARALYTIC SHELLFISH TOXINS; GENE-CLUSTER; SAXITOXIN BIOSYNTHESIS; LIQUID-CHROMATOGRAPHY; CELL-CYCLE; ALEXANDRIUM; GROWTH; DIVERSITY; PROFILES; TOXICITY	The paralytic shellfish toxin (PST)-producing dinoflagellate Gymnodinium catenatum grows in association with a complex marine bacterial community that is both essential for growth and can alter culture growth dynamics. Using a bacterial community replacement approach, we examined the intracellular PST content, production rate, and profile of G. catenatum cultures grown with bacterial communities of differing complexity and composition. Clonal offspring were established from surface-sterilized resting cysts (produced by sexual crosses of strain GCDE06 and strain GCLV01) and grown with: 1) complex bacterial communities derived from each of the two parent cultures; 2) simplified bacterial communities composed of the G. catenatum-associated bacteria Marinobacter sp. strain DG879 or Alcanivorax sp. strain DG881; 3) a complex bacterial community associated with an untreated, unsterilized sexual cross of the parents. Toxin content (STX-equivalent per cell) of clonal offspring (134-197 fmol STX cell(-1)) was similar to the parent cultures (169-206 fmol STX cell(-1)), however cultures grown with single bacterial types contained less toxin (134-146 fmol STX cell(-1)) than offspring or parent cultures grown with more complex mixed bacterial communities (152-176 fmol STX cell(-1)). Specific toxin production rate (fmol STX day(-1)) was strongly correlated with culture growth rate. Net toxin production rate (fmol STX cell(-1) day(-1)) did not differ among treatments, however, mean net toxin production rate of offspring was 8-fold lower than the parent cultures, suggesting that completion of the sexual lifecycle in laboratory cultures leads to reduced toxin production. The PST profiles of offspring cultures were most similar to parent GCDE06 with the exception of cultures grown with Marinobacter sp. DG879 which produced higher proportions of dcGTX2+3 and GC1+2, and lower proportions of C1+2 and C3+4. Our data demonstrate that the bacterial community can alter intracellular STX production of dinoflagellates. In G. catenatum the mechanism appears likely to be due to bacterial effects on dinoflagellate physiology rather than bacterial biotransformation of PST toxins.

Since 1998, Dungeness crabs exhibiting pink- to orange-colored joints and opaque white musculature have been sporadically observed in low prevalence from the Fraser River delta of British Columbia, Canada. We provide histological, ultrastructural, and molecular evidence that this condition is caused by a new microsporidian parasite. Crabs displaying gross symptoms were confirmed to have heavy infections of ovoid-shaped microsporidian spores (similar to 1.8 x 1.4 mu m in size) within muscle bundles of the skeletal musculature. The parasite apparently infected the outer periphery of each muscle bundle, and then proliferated into the muscle fibres near the centre of each infected bundle. Light infections were observed in heart tissues, and occasionally spores were observed within the fixed phagocytes lining the blood vessels of the hepatopancreas. Transmission electron microscopy (TEM) revealed multiple life stages of a monokaryotic microsporidian parasite within the sarcoplasm of muscle fibres. Molecular analysis of partial small subunit rRNA sequence data from the new species revealed an affinity to Ameson, a genus of Microsporidia infecting marine crustaceans. Based on morphological and molecular data, the new species is distinct from Nadelspora canceri, a related microsporidian that also infects the muscles of this host. At present, little is known about the distribution, seasonality, and transmission of A. metacarcini in M. magister.

COMPRESSUM; PROTOCERATIUM-RETICULATUM; FLUORESCENCE DETECTION; SURFACE SEDIMENTS; MEXICO; SALINITY; PLATE; BAY	Pyrodinium bahamense is a meroplanktonic dinoflagellate that produces paralytic shellfish toxins that cause human poisoning along tropical and subtropical coasts. Cyst morphology, germination characteristics, and toxicity were investigated using samples from Isla San Jose in the Gulf of California. Morphology was observed through light and scanning electron microscopy. Germination was tested at different temperature (15 degrees C-35 degrees C) and salinity (15-35) conditions in different culture media (natural seawater, GSe, and f/2). To elucidate toxicity of vegetative cells grown from cyst germination, nine strains were subject to toxin analyses through fluorescence high-performance liquid chromatography. Morphological features and size of cysts generally agree with previous descriptions, particularly morphotypes found in the subtropical North Atlantic, where P. bahamense var. bahamense occurs. Cysts exhibit thermophilic and euryhaline characteristics. Highest germination occurred from 20 degrees C to 35 degrees C with the peak between 25 degrees C and 30 degrees C. Excystment occurred at salinities from 20 to 35. Germination occurred in the three culture media, but was highest in the optimal temperature range in the culture medium that included terrestrial soil extract and selenium. Only one strain exhibited toxicity with high saxitoxin concentration (95 pg STX eq cell(-1)).

The species was exposed to increasing free zinc (1.34x10(-7)M-3.98x10(-6)M) or lead (5.13x10(-9)M-1.82x10(-7)M) concentra-tions. Low metal levels ([Zn2+]=1.34x10(-7)M; [Pb2+]=5.13x10(-9)M) had no effect on cell growth. Toxic effects were observed from higher metal contamination ([Zn2+]=3.98x10(-6)M; [Pb2+]=6.54x10(-8)M), as a conversion of vegetative cells into cysts. Analysis of the released FDOM by three-dimensional (3-D) fluorescence spectroscopy was achieved, using the parallel factor analysis (PARAFAC). The PARAFAC modeling revealed four components associated with two contributions: one related to the biological activity; the other linked to the organic matter decomposition in the culture medium. The C1 component combined a tryptophan peak and characteristics of humic substances, whereas the C2 component was considered as a tryptophan protein fluorophore. The two others C3 and C4 components were associated with marine organic matter production. Relea-sed fluorescent substances were induced by low ([Zn2+]=1.34x10(-7)M; [Pb2+]=5.13x10(-9)M) and moderate([Zn2+]=6.21x10(-7)M; [Pb2+]=2.64x10(-9)M) metal concentrations, suggesting the activation of cellular mechanisms in response to metal stress, to exudate FDOM that could complex metal cations and reduce their toxicity toward A.catenella cells.

This could influence the vertical distribution of vertically migrating dinoflagellates. We studied the diel vertical distribution of the dinoflagellates Heterocapsa triquetra and Prorocentrum minimum using stratified laboratory columns with two thermoclines of different strength (Delta TA degrees A = 10 or 17 A degrees C), with below cline temperature of 8 A degrees C. Above the thermocline, nutrient depletion simulated the natural summer conditions in the Baltic Sea. Our study shows that H. triquetra and P. minimum can behave differently in terms of their vertical occurrence, both in space and in time when subjected to thermoclines of different strength. Also, both dinoflagellate species showed species-specific distribution patterns. In the Delta TA degrees A = 10 A degrees C treatment, H. triquetra cells performed a diel vertical migration (DVM) behavior just above the thermocline, but not in the Delta TA degrees A = 17 A degrees C. In the Delta TA degrees A = 17 A degrees C, the cells did not migrate and cell densities in the water column decreased over time. Opposing results were observed for P. minimum, where a DVM pattern was found exclusively below the thermocline of Delta TA degrees A = 17 A degrees C, while in the Delta TA degrees A = 10 A degrees C treatment, no clear DVM pattern was observed, and the highest number of cells were found in the cold bottom water. These results indicate that an increase in thermal stratification can influence species-specific dinoflagellate distribution, behavior, and survival.

Forty-eight dinocyst types were identified, mainly dominated by Brigantidinium simplex, Votadinum spinosum, Alexandrium pseudogonyaulax, Alexandrium catenella, and Lingulodinum machaerophorum along with many round brown cysts and spiny round brown cysts. Cysts ranged from 1276 to 20126 cysts g(-1) dry weight sediment. Significant differences in cyst distribution pattern were recorded among the zones, with a higher cyst abundance occurring in the lagoon's inner areas. Redundancy analyses showed two distinct associations of dinocysts according to location and environmental variables. Ballast water discharges are potential introducers of non-indigenous species, especially harmful ones such as A. catenella and Polysphaeridium zoharyi, with currents playing a pivotal role in cyst distribution. Findings concerning harmful cyst species indicate potential seedbeds for initiation of future blooms and outbreaks of potentially toxic species in the lagoon. (C) 2014 Elsevier Ltd.

This lagoon is the subject of many anthropogenic impacts, such as holding important fishing and aquaculture activities. A. pseudogonyaulax has been shown to produce Goniodomin A, which is a biologically-active compound. We showed that this dinoflagellate produces two types of resting cysts, which could be distinguished by the presence or the absence of a paratabulate wall. The average cyst density across the whole lagoon was rather high, reaching 639 cysts g(-1) of dry sediment (DS). Cyst densities varied widely among the sampled stations, with the highest density of 1685 cyst g(-1) DS being recorded at station 51 near a mussel farm. With respect to sediment characteristics, the highest cyst densities were found within silty sediments with high water content values. The distribution of A. pseudongoyaulax cysts in Bizerte lagoon appears to be related to hydrodynamic factors. (C) 2014 Elsevier Ltd. All rights reserved.

The basic cell components (nucleus, chloroplasts, mitochondria, amphiesma, Golgi complex, and accumulative bodies) are described. An expanded and updated description of the chloroplasts and accumulative bodies is given. Crystalline aggregates characteristic of hypnozygotic cysts were found in the genus Ostreopsis for the first time. The data are compared with the results of ultrastructural studies on Ostreopsis cf. ovata that inhabits the Adriatic and the Caribbean seas and the coastal waters of Jeju Island (South Korea). New features of the structure of some organelles in Ostreopsis cf. ovata from Russian waters were revealed.	[Kreshchenovskaya, M. A.; Orlova, T.

Large-scale bloom of <i>Akashiwo sanguinea</i> in the Northern California current system in 2009	HARMFUL ALGAE			English	Article						Akashiwo sanguinea; Cysts; Dinoglagellates; HABS; Harmful algal blooms; Seabird mortality; Surf zone; Upwelling	HARMFUL ALGAL BLOOMS; RED TIDE; PHYTOPLANKTON; OREGON; GROWTH	Significant seabird mortality on the Oregon (OR) and Washington (WA) coast in 2009 has been attributed to a massive bloom of the dinoflagellate Akashiwo sanguinea (K. Hirasaka) G. Hansen & O. Moestrup. Initial, albeit limited, observations suggested this bloom began in WA and reached OR waters through southward transport. Here, we explore a combination of remote sensing products and an exceptional latitudinal dataset of plankton counts collected in the surfzone and offshore in OR and WA coastal waters. Records of satellite ocean color for this period support the new finding that blooms were concurrent in OR and WA waters, with no evidence for latitudinal propagation as had been previously suggested. Plankton analyses further indicate that there was a rapid and synchronized increase of A. sanguinea between late August and mid-September of 2009 along wide swaths of the OR and WA coasts. Bloom onset occurred during a prolonged quiescent and warm period in late August-early September, near the end of the March-October upwelling phase. An upwelling event in October likely contributed to foam production through vertical mixing of A. sanguinea rich waters. Bloom intensity peaked earlier and at higher levels in WA waters as compared to OR with cell concentrations exceeding 1.5 x 10(6) cells L-1 (WA) and similar to 350,000 cells L-1 (OR). In OR samples, A. sanguinea cells comprised upwards of 90% of dinoflagellate cell counts and similar to 30% of total phytoplankton cells. At some locations, A. sanguinea persisted well into November-December of 2009, during which time satellite sea surface temperature records indicated anomalously warm surface waters (up to similar to 5 degrees C greater than climatological means). Taken together, the data reveal a HAB event of a magnitude unprecedented in over a decade of observations. We hypothesize that these blooms originated from either a cryptic cyst bed and/or a pelagic seed bank of viable vegetative cells. (C) 2014 Elsevier B.V. All rights reserved.

Tissue Distribution of Amino Acid- and Lipid-Brevetoxins after Intravenous Administration to C57BL/6 Mice	CHEMICAL RESEARCH IN TOXICOLOGY			English	Article							FLORIDA RED TIDE; INTRATRACHEAL INSTILLATION; PTYCHODISCUS-BREVIS; GREENSHELL MUSSELS; NEW-ZEALAND; RATS; METABOLITES; ELIMINATION; SHELLFISH; SEMISYNTHESIS	Brevetoxins produced during algal blooms of the dinoflagellate Karenia are metabolized by shellfish into reduction, oxidation, and conjugation products. Brevetoxin metabolites comprising amino acid- and lipid conjugates account for a large proportion of the toxicity associated with the consumption of toxic shellfish. However, the disposition of these brevetoxin metabolites has not been established. Using intravenous exposure to C57BL/6 mice, we investigated the disposition in the body of three radiolabeled brevetoxin metabolites. Amino acid brevetoxin conjugates represented by S-desoxy-BTX-B2 (cysteine-BTX-B) and lipid brevetoxin conjugates represented by N-palmitoyl-S-desoxy-BTX-B2 were compared to dihydro-BTX-B. Tissue concentration profiles were unique to each of the brevetoxin metabolites tested, with dihydro-BTX-B being widely distributed to all tissues, S-desoxy-BTX-B2 concentrated in kidney, and N-palmitoyl-S-desoxy-BTX-B2 having the highest concentrations in spleen, liver, and lung. Elimination patterns were also unique: dihydro-BTX-B had a greater fecal versus urinary elimination, whereas urine was a more important elimination route for S-desoxy-BTX-B2, and N-palmitoyl-S-desoxy-BTX-B2 persisted in tissues and was eliminated equally in both urine and feces. The structures particular to each brevetoxin metabolite resulting from the reduction, amino acid conjugation, or fatty acid addition of BTX-B were likely responsible for these tissue-specific distributions and unique elimination patterns. These observed differences provide further insight into the contribution each brevetoxin metabolite class has to the observed potencies.

The morphological destruction was observed in both spiny- and naked type cysts after passage through the gut of Capitella sp., and this seemed to occur rapidly for naked-type cysts. In addition, the germination of both spiny- and naked-type cysts isolated from fecal pellets on day 2 of harvesting was significantly reduced and subsequently completely abolished, in contrast to previous findings from ingestion studies. Our results indicate that continual grazing by Capitella sp. within a restricted habitat can compromise the survival of S. trochoidea cysts. (C) 2014 Elsevier B.V. All rights reserved.

Australian Dust Storm Associated with Extensive <i>Aspergillus sydowii</i> Fungal "Bloom" in Coastal Waters	APPLIED AND ENVIRONMENTAL MICROBIOLOGY			English	Article								A massive central Australian dust storm in September 2009 was associated with abundant fungal spores (150,000/m(3)) and hyphae in coastal waters between Brisbane (27 degrees S) and Sydney (34 degrees S). These spores were successfully germinated from formalinpreserved samples, and using molecular sequencing of three different genes (the large subunit rRNA gene [LSU], internal transcribed spacer [ITS], and beta-tubulin gene), they were conclusively identified as Aspergillus sydowii, an organism circumstantially associated with gorgonian coral fan disease in the Caribbean. Surprisingly, no human health or marine ecosystem impacts were associated with this Australian dust storm event. Australian fungal cultures were nontoxic to fish gills and caused a minor reduction in the motility of Alexandrium or Chattonella algal cultures but had their greatest impacts on Symbiodinium dinoflagellate coral symbiont motility, with hyphae being more detrimental than spores. While we have not yet seen any soft coral disease outbreaks on the Australian Great Barrier Reef similar to those observed in the Caribbean and while this particular fungal population was non-or weakly pathogenic, our observations raise the possibility of future marine ecosystem pathogen impacts from similar dust storms harboring more pathogenic strains.

J	Arancio, M; Sourisseau, M; Souissi, S				Arancio, Marc; Sourisseau, Marc; Souissi, Sami			Processes leading to the coexistence of a host and its parasitoid in homogeneous environments: The role of an infected dormant stage	ECOLOGICAL MODELLING			English	Article						Individual-based model; Dinoflagellate; Parasitoid; Amoebophrya; Host-parasite interactions; Sources of coexistence	POPULATION-DYNAMICS; DINOFLAGELLATE BLOOMS; CHESAPEAKE BAY; ONAGAWA BAY; DINOPHYCEAE; GROWTH; CYSTS; PHYTOPLANKTON; SCRIPPSIELLA; TEMPERATURE	Theoretical studies have usually been used to explain host-parasitoid persistence in conditions of spatial heterogeneity or in homogeneous environments with specific conditions. In shallow estuaries where spatial heterogeneity is prevented by tides and river input, a common host-parasitoid system (dinoflagellate-Amoebophrya spp.) is able to persist even in the absence of specific conditions described in the literature. Recent observations have revealed that the cyst stage (during which the dinoflagellate host can survive in difficult environmental conditions in a dormant stage) can be infected by the parasitoid. The encystment/excystment process is suspected to be the basis for the long-term persistence of the system. In this work, the coexistence of Amoebophrya spp. and their hosts in homogeneous environments has been tested with an individual-based model of host-parasitoid interactions. Three processes that enable the coexistence were introduced into our model: (1) modifications in infection parameters, (2) a tritrophic food web and (3) a host encystment-excystment process. The persistence of the system was obtained in mixed conditions in all cases; however, the conditions required to obtain persistence with the infection parameter modifications were unrealistic. The tritrophic food web scenario produced short, stable, 10-d-long cycles in which the control of the parasite population in the environment was difficult to observe. The excystment process appears to be responsible for the interannual persistence of the system. Durable cycles with periods of 50 d were produced despite the unstable conditions. Moreover, these cycles did not depend on the proportion of infected cysts as long as a portion of the cysts remained healthy. (c) 2014 Elsevier B.V. All rights reserved.

Thirty years - <i>Alexandrium fundyense</i> cyst, bloom dynamics and shellfish toxicity in the Bay of Fundy, eastern Canada	DEEP-SEA RESEARCH PART II-TOPICAL STUDIES IN OCEANOGRAPHY			English	Article						Alexandrium fundyense; Bay of Fundy; Harmful algal blooms; Cysts	DINOFLAGELLATE GONYAULAX-EXCAVATA; TOXINS; GULF; CIRCULATION; OYSTERS	Sediment and water samples were collected for Alexandrium fundyense spatial and temporal distribution and abundance at more than 120 locations throughout the Bay of Fundy during the summers and winters of 1980-1984. These broad surveys have been repeated at various times through the past 30 years, with more regular sampling since 2004. In addition, A. fundyense abundance has been monitored at several locations within the Bay of Fundy at weekly intervals from April to November and monthly during the remaining months since 1988. Paralytic Shellfish Poisoning (PSP) toxins in shellfish (notably Mya arenaria) have also been monitored at multiple locations in the Bay of Fundy since 1943. The datasets were examined to determine relationships and roles between overwintering resting cysts, bloom initiation, bloom decline, motile cell dispersal and A. fundyense motile populations and resulting shellfish toxicity since 1980. Cysts are widely dispersed throughout the Bay of Fundy in the offshore, inshore and intertidal zones with the largest deposits located in the offshore in silt/clay sediments to the east and north of Grand Manan Island at depths of 60-180 m. Results show that there is a constant stable source of cysts in the Bay of Fundy with highest concentrations of cysts (9780 cysts cm(-3)) observed in 2010 and highest concentrations of A. fundyense motile cells (18 x 10(6) cells L-1) observed in 1980. Interannual changes in abundance in A. fundyense populations, resting cysts and the temporal trends in M. arenaria toxicity are discussed. Results show that there was no relationship between the abundance of overwintering cysts and the magnitude of A. fundyense blooms. The offshore seed beds appear to be relatively constant in cyst density among most years and serve as an important source for the motile cells that lead to initiation of major blooms and resulting shellfish toxicity throughout the Bay of Fundy.

These blooms often lead to paralytic shellfish poisoning (PSP) and extensive closures of shellfish beds. We report here on time-series sediment trap deployments completed at four offshore locations in the gulf between 2005 and 2010 as components of two ECOHAB-GOM field programs. Data presented documents the substantial spatial and temporal fluctuations in Alexandrium fundyense cyst fluxes in the gulf. Cyst delivery out of the euphotic zone peaked primarily between July and August following annual spring-summer Alexandrium blooms and was greatest in the western gulf. At all sites, cyst flux maxima to the subsurface waters were rarely coincident with seasonal peaks in the total mass export of particulate material indicating that cyst delivery was primarily via individually sinking cysts. Where persistent benthic nepheloid layers (BNLs) exist, significant sediment resuspension input of cysts to the near-bottom water column was evidenced by deep cyst fluxes that were up to several orders of magnitude greater than that measured above the BNL. The largest cyst fluxes in the BNL were observed in the eastern gulf, suggesting greater resuspension energy and BNL cyst inventories in this region. Temporal similarities between peak cyst export out of the upper ocean and peak cyst fluxes in the BNL were observed and document the contribution of seasonal, newly formed cysts to the BNL. The data however also suggest that many Alexandrium cells comprising the massive, short-lived blooms do not transition into cysts. Time-series flow measurements and a simple 1D model demonstrate that the BNL cyst fluxes reflect the combined effects of tidal energy-maintained resuspension, deposition, and input of cysts from the overlying water column.

J., Jr.			Benthic nepheloid layers in the Gulf of Maine and <i>Alexandrium</i> cyst inventories	DEEP-SEA RESEARCH PART II-TOPICAL STUDIES IN OCEANOGRAPHY			English	Article						Benthic nepheloid layer; Suspended particulate matter; Gulf of Maine; Alexandrium fundyense; Cysts	BOTTOM BOUNDARY-LAYER; SANTA-CATALINA BASIN; CONTINENTAL-SHELF; GEORGES-BANK; SEDIMENT RESUSPENSION; HYDROGRAPHIC STRUCTURE; FUNDYENSE CYSTS; WILKINSON BASIN; COASTAL CURRENT; NEAR-BOTTOM	Cysts residing in benthic nepheloid layers (BNLs) documented in the Gulf of Maine have been proposed as a possible source of inoculum for annual blooms of a toxic dinoflagellate in the region. Herein we present a spatially extensive data set of the distribution and thickness of benthic nepheloid layers in the Gulf of Maine and the abundance and inventories of suspended Alexandrium fundyense cysts within these near-bottom layers. BNLs are pervasive throughout the gulf and adjacent Bay of Fundy with maximum layer thicknesses of 50-60 m observed. Mean BNL thickness is 30 m in the eastern gulf and Bay of Fundy, and 20 m in the western gulf. Cyst densities in the near-bottom particle resuspension layers varied by three orders of magnitude across the gulf with maxima of 10(5) cysts m(-3). An important interconnection of elevated BNL cyst densities is observed between the Bay of Fundy, the Maine Coastal Current and the south-central region of the gulf. BNL cyst inventories estimated for the eastern and western gulf are each on the order of 10(15) cysts, whereas the BNL inventory in the Bay of Fundy is on the order of 10(16). Although BNL cyst inventories in the eastern and western gulf are 1-2 orders of magnitude smaller than the abundance of cysts in the upper 1 cm of sediment in those regions, BNL and sediment-bound cyst inventories are comparable in the Bay of Fundy. The existence of widespread BNLs containing substantial cyst inventories indicates that these near-bottom layers represent an important source of germinating A. fundyense cysts in the region.

Investigating the importance of sediment resuspension in <i>Alexandrium fundyense</i> cyst population dynamics in the Gulf of Maine	DEEP-SEA RESEARCH PART II-TOPICAL STUDIES IN OCEANOGRAPHY			English	Article						Sediment transport; Bottom stress; Sediment resuspension; Harmful algal blooms; Gulf of Maine; Alexandrium fundyense; HAB	PHYSICAL-BIOLOGICAL MODEL; GONYAULAX-TAMARENSIS; WESTERN GULF; DINOFLAGELLATE CYSTS; SETTLING VELOCITY; MASSACHUSETTS BAY; CONTINENTAL-SHELF; TRANSPORT; BLOOMS; GERMINATION	Cysts of Alexandrium fundyense, a dinoflagellate that causes toxic algal blooms in the Gulf of Maine, spend the winter as dormant cells in the upper layer of bottom sediment or the bottom nepheloid layer and germinate in spring to initiate new blooms. Erosion measurements were made on sediment cores collected at seven stations in the Gulf of Maine in the autumn of 2011 to explore if resuspension (by waves and currents) could change the distribution of over-wintering cysts from patterns observed in the previous autumn; or if resuspension could contribute cysts to the water column during spring when cysts are viable. The mass of sediment eroded from the core surface at 0.4 Pa ranged from 0.05 kg m(-2) near Grand Manan Island, to 0.35 kg m(-2) in northern Wilkinson Basin. The depth of sediment eroded ranged from about 0.05 mm at a station with sandy sediment at 70 m water depth on the western Maine shelf, to about 1.2 mm in clayey-silt sediment at 250 m water depth in northern Wilkinson Basin. The sediment erodibility measurements were used in a sediment-transport model forced with modeled waves and currents for the period October 1, 2010 to May 31, 2011 to predict resuspension and bed erosion. The simulated spatial distribution and variation of bottom shear stress was controlled by the strength of the semi-diurnal tidal currents, which decrease from east to west along the Maine coast, and oscillatory wave-induced currents, which are strongest in shallow water. Simulations showed occasional sediment resuspension along the central and western Maine coast associated with storms, steady resuspension on the eastern Maine shelf and in the Bay of Fundy associated with tidal currents, no resuspension in northern Wilkinson Basin, and very small resuspension in western Jordan Basin. The sediment response in the model depended primarily on the profile of sediment erodibility, strength and time history of bottom stress, consolidation time scale, and the current in the water column. Based on analysis of wave data from offshore buoys from 1996 to 2012, the number of wave events inducing a bottom shear stress large enough to resuspend sediment at 80 m ranged from 0 to 2 in spring (April and May) and 0 to 10 in winter (October through March). Wave-induced resuspension is unlikely in water greater than about 100 m deep. The observations and model results suggest that a millimeter or so of sediment and associated cysts may be mobilized in both winter and spring, and that the frequency of resuspension will vary interannually. Depending on cyst concentration in the sediment and the vertical distribution in the water column, these events could result in a concentration in the water column of at least 10(4) cysts m(-3). In some years, resuspension events could episodically introduce cysts into the water column in spring, where germination is likely to be facilitated at the time of bloom formation. An assessment of the quantitative effects of cyst resuspension on bloom dynamics in any particular year requires more detailed investigation. Published by Elsevier Ltd.

The germling cells and their vegetative progeny are assumed to be subject to mortality while in complete darkness, as they swim to illuminated surface waters. To test the validity of this assumption we conducted laboratory investigations of cyst viability and the survival of the germling cells and their vegetative progeny during prolonged exposure to darkness at a temperature of 6 degrees C, simulating the conditions in deep Gulf of Maine waters. We isolated cysts from bottom sediments collected in the Gulf of Maine under low red light and incubated them in 96-well tissue culture-plates in culture medium under a 10:14 h light:dark cycle and under complete darkness. Cyst viability was high, with excystment frequency reaching 90% in the illuminated treatment after 30 days and in the dark treatment after 50 days. Average germination rates were 0.062 and 0.038 d(-1) for light and dark treatments, respectively. The dark treatment showed an approximately 2-week time lag in maximum germination rates compared to the light treatment. Survival of germlings was considerably lower in the dark treatment. In the light treatments, 47% of germinated cysts produced germlings that were able to survive for 7 days and produce vegetative progeny, i.e., there were live cells in the well along with an empty cyst at least once during the experiment. In the dark treatments 12% of the cysts produced germlings that were able to survive for the same length of time. When dark treatments are scaled to take into account non-darkness related mortality, approximately 28% of the cysts produced germlings that were able to survive for at least 7 days. Even though cysts are able to germinate in darkness, the lack of illumination considerably reduces survival rate of germling cells. In addition to viability of cysts in surface sediments and the near-bottom nepheloid layer, survivability of germling cells and their vegetative progeny at aphotic depths is an important consideration in assessing the quantitative role of deep-coastal cyst seed beds in bloom formation.

A red tide of <i>Alexandrium fundyense</i> in the Gulf of Maine	DEEP-SEA RESEARCH PART II-TOPICAL STUDIES IN OCEANOGRAPHY			English	Article						Phytoplankton; Population dynamics; Red tides; Cysts; Paralytic shellfish poisoning; USA; Gulf of Maine	DINOFLAGELLATE GONYAULAX-EXCAVATA; PHYSICAL-BIOLOGICAL MODEL; WESTERN GULF; ALGAL BLOOMS; CELL-CYCLE; TAMARENSE; PHYTOPLANKTON; CYSTS; BIOGEOGRAPHY; HYPOTHESES	In early July 2009, an unusually high concentration of the toxic dinoflagellate Alexandrium fundyense occurred in the western Gulf of Maine, causing surface waters to appear reddish brown to the human eye. The discolored water appeared to be the southern terminus of a large-scale event that caused shellfish toxicity along the entire coast of Maine to the Canadian border. Rapid-response shipboard sampling efforts together with satellite data suggest the water discoloration in the western Gulf of Maine was a highly ephemeral feature of less than two weeks in duration. Flow cytometric analysis of surface samples from the red water indicated the population was undergoing sexual reproduction. Cyst fluxes downstream of the discolored water were the highest ever measured in the Gulf of Maine, and a large deposit of new cysts was observed that fall. Although the mechanisms causing this event remain unknown, its timing coincided with an anomalous period of downwelling-favorable winds that could have played a role in aggregating upward-swimming cells. Regardless of the underlying causes, this event highlights the importance of short-term episodic phenomena on regional population dynamics of A. fundyense. (C) 2013 Elsevier Ltd. All rights reserved.

Complexities of bloom dynamics in the toxic dinoflagellate <i>Alexandrium fundyense</i> revealed through DNA measurements by. imaging flow cytometry coupled with species-specific rRNA probes	DEEP-SEA RESEARCH PART II-TOPICAL STUDIES IN OCEANOGRAPHY			English	Article						Alexandrium fundyense; A. tamarense Group I; Algal bloom dynamics; Imaging flow cytometry; Microalgal life cycles	GONYAULAX-TAMARENSIS LEBOUR; CELL-CYCLE; CYST FORMATION; CAPE-COD; DINOPHYCEAE; MAINE; GULF; IDENTIFICATION; BIOGEOGRAPHY; TEMPERATURE	Measurements of the DNA content of different protist populations can shed light on a variety of processes, including cell division, sex, prey ingestion, and parasite invasion. Here, we modified an Imaging FlowCytobot (IFCB), a custom-built flow cytometer that records images of microplankton, to measure the DNA content of large dinoflagellates and other high-DNA content species. The IFCB was also configured to measure fluorescence from Cy3-labeled rRNA probes, aiding the identification of Alexandrium fundyense (syn. A. tamarense Group I), a photosynthetic dinoflagellate that causes paralytic shellfish poisoning (PSP). The modified IFCB was used to analyze samples from the development, peak and termination phases of an inshore A. fundyense bloom (Salt Pond, Eastham, MA, USA), and from a rare A. fimdyense 'red tide' that occurred in the western Gulf of Maine, offshore of Portsmouth, NH (USA). Diploid or G2 phase ('2C') A. fundyense cells were frequently enriched at the near-surface, suggesting an important role for aggregation at the air-sea interface during sexual events. Also, our analysis showed that large proportions of A. fundyense cells in both the Salt Pond and red tide blooms were planozygotes during bloom decline, highlighting the importance of sexual fusion to bloom termination. At Salt Pond, bloom decline also coincided with a dramatic rise in infections by the parasite genus Amoebophrya. The samples that were most heavily infected contained many large cells with higher DNA-associated fluorescence than 2C vegetative cells, but these cells' nuclei were also frequently consumed by Amoebophrya trophonts. Neither large cell size nor increased DNA-associated fluorescence could be replicated by infecting an A. fundyense culture of vegetative cells. Therefore, we attribute these characteristics of the large Salt Pond cells to planozygote maturation rather than Amoebopluya infection, though an interaction between infection and planozygote maturation may also have contributed. The modified IFCB is a valuable tool for exploring the conditions that promote sexual transitions by dinoflagellate blooms but care is needed when interpreting results from samples in which parasitism is prevalent.

Understanding interannual, decadal level variability in paralytic shellfish poisoning toxicity in the Gulf of Maine: The HAB Index	DEEP-SEA RESEARCH PART II-TOPICAL STUDIES IN OCEANOGRAPHY			English	Article						Alexandrium fundyense; Harmful algal blooms; HABs; PSP; HAB Index	RED-TIDE DINOFLAGELLATE; ALEXANDRIUM-FUNDYENSE POPULATIONS; GONYAULAX-EXCAVATA; WESTERN GULF; RESTING CYSTS; PUGET-SOUND; NEW-ENGLAND; BLOOMS; DYNAMICS; HYPOTHESES	A major goal in harmful algal bloom (HAB) research has been to identify mechanisms underlying interannual variability in bloom magnitude and impact. Here the focus is on variability in Alexandrium fundyense blooms and paralytic shellfish poisoning (PSP) toxicity in Maine, USA, over 34 years (1978-2011). The Maine coastline was divided into two regions - eastern and western Maine, and within those two regions, three measures of PSP toxicity (the percent of stations showing detectable toxicity over the year, the cumulative amount of toxicity per station measured in all shellfish (mussel) samples during that year, and the duration of measurable toxicity) were examined for each year in the time series. These metrics were combined into a simple HAB Index that provides a single measure of annual toxin severity across each region. The three toxin metrics, as well as the HAB Index that integrates them, reveal significant variability in overall toxicity between individual years as well as long-term, decadal patterns or regimes. Based on different conceptual models of the system, we considered three trend formulations to characterize the long-term patterns in the Index - a three-phase (mean-shift) model, a linear two-phase model, and a pulse-decline model. The first represents a "regime shift" or multiple equilibria formulation as might occur with alternating periods of sustained high and low cyst abundance or favorable and unfavorable growth conditions, the second depicts a scenario of more gradual transitions in cyst abundance or growth conditions of vegetative cells, and the third characterizes a "sawtooth" pattern in which upward shifts in toxicity are associated with major cyst recruitment events, followed by a gradual but continuous decline until the next pulse. The fitted models were compared using both residual sum of squares and Akaike's Information Criterion. There were some differences between model fits, but none consistently gave a better fit than the others. This statistical underpinning can guide efforts to identify physical and/or biological mechanisms underlying the patterns revealed by the HAB Index. Although A. fundyense cyst survey data (limited to 9 years) do not span the entire interval of the shellfish toxicity records, this analysis leads us to hypothesize that major changes in the abundance of A. fundyense cysts may be a primary factor contributing to the decadal trends in shellfish toxicity in this region. The HAB Index approach taken here is simple but represents a novel and potentially useful tool for resource managers in many areas of the world subject to toxic HABs. (C) 2013 Elsevier Ltd.

Sediment samples were recovered from 11 stations in May 2009 at Cabras Lagoon, eight stations in May 2010 at Corru S'Ittiri Lagoon, and five stations in May 2011 at Santa Giusta Lagoon. Fifty-three dinoflagellate cyst morphotypes were identified. Sixteen species are first reports for the lagoons, and two for the Mediterranean Sea. Moreover, a new Scrippsiella species was discovered in Cabras. Seven harmful algal species were identified, primarily belonging to the potentially toxic genus Alexandrium. Total cyst abundance, number of morphotypes, and assemblages varied among lagoons, and each lagoon showed a distinct morphotype composition. A degree of heterogeneity was also detected within lagoon. Cabras and Santa Giusta cyst assemblages were characterised by morphotypes belonging to the autotrophic genus Scrippsiella, whereas Corru S'Ittiri assemblages showed dominance of heterotrophic morphotypes, including Protoperidinium cf tricingulatum. Differentiation among lagoons was also evident according to environmental conditions. Salinity proved to be a fundamental variable in determining total cyst abundance, morphotype number, and composition. This study was among the first to examine dinoflagellate cyst composition in coastal lagoons, especially from the Mediterranean region, and contributed data that increased our knowledge of cyst-producing dinoflagellates in these environments.

We also explore the relative utility of two measures of cyst abundance and demonstrate that GOM cyst counts can be normalized to sediment volume, revealing meaningful patterns equivalent to those determined with dry weight normalization. Cyst concentrations were highly variable spatially. Two distinct seedbeds (defined here as accumulation zones with > 300 cysts cm(-3)) are evident, one in the Bay of Fundy (BOF) and one in mid-coast Maine. Overall, seedbed locations remained relatively constant through time, but their area varied 3-4 fold, and total cyst abundance more than 10 fold among years. A major expansion of the mid-coast Maine seedbed occurred in 2009 following an unusually intense A. fundyense bloom with visible red-water conditions, but that feature disappeared by late 2010. The regional system thus has only two seedbeds with the bathymetry, sediment characteristics, currents, biology, and environmental conditions necessary to persist for decades or longer. Strong positive correlations were confirmed between the abundance of cysts in both the 0-1 and the 0-3 cm layers of sediments in autumn and geographic measures of the extent of the bloom that occurred the next year (i.e., cysts --> blooms), such as the length of coastline closed due to shellfish toxicity or the southernmost latitude of shellfish closures. In general, these metrics of bloom geographic extent did not correlate with the number of cysts in sediments following the blooms (blooms --> cysts). There are, however, significant positive correlations between 0-3 cm cyst abundances and metrics of the preceding bloom that are indicative of bloom intensity or vegetative cell abundance (e.g., cumulative shellfish toxicity, duration of detectable toxicity in shellfish, and bloom termination date). These data suggest that it may be possible to use cyst abundance to empirically forecast the geographic extent of the forthcoming bloom and, conversely, to use other metrics from bloom and toxicity events to forecast the size of the subsequent cyst population as the inoculum for the next year's bloom. This is an important step towards understanding the excystment/encystment cycle in A. fundyense bloom dynamics while also augmenting our predictive capability for this HAB-forming species in the GOM.

Bioturbation, germination and deposition of <i>Alexandrium fundyense</i> cysts in the Gulf of Maine	DEEP-SEA RESEARCH PART II-TOPICAL STUDIES IN OCEANOGRAPHY			English	Article						Bioturbation; Cyst; Germination; Model; Toxic dinoflagellates; Gulf of Maine; Alexandrium fundyense	DINOFLAGELLATE CYSTS; VARIABILITY; SEDIMENTS; DYNAMICS; PATTERNS; BLOOM; DINOPHYCEAE; ABUNDANCE; TOXICITY; MODEL	Like many other dinoflagellate species, Alexandrium fundyense possesses a benthic resting cyst which enables long-term persistence and annual blooms of this species in the Gulf of Maine. The size and extent of these harmful algal blooms are associated with high cyst concentrations in the top 1 cm of sediment. Despite the importance of this resting stage in the life history of A. fundyense, little work has been done on bioturbation of cysts in the deep-water cyst beds of the western Gulf of Maine. Our work intensively examined one site within a major regional "seedbed" from February 2003 until August 2005, a time span that included an extraordinarily large bloom of A. fundyense in 2005. Over the course of 2 years we collected samples for benthic infauna and cyst profiles down to a depth of 30 cm. We also measured sediment porosity, organic carbon, Pb-210, and porewater dissolved oxygen. On several dates we measured depth profiles of cyst autofluorescence. Profiles of cysts revealed large subsurface maxima peaking between 10 and 15 cm depth with cyst concentrations declining strongly toward the sediment surface. On one sampling date (August 2004) we observed a cyst concentration peak at the sediment surface. Using these data we constructed a mechanistic model of cyst bioturbation, mortality, germination, and deposition. Modeled bioturbation was calibrated using Pb-210 and modeled cyst profiles were compared to measured profiles. Model runs with constant and interannually-varying rates of cyst deposition produced similar time-averaged cyst profiles. Results indicate that the deeper portions of cyst profiles are determined primarily by bioturbation, germination and cyst mortality and less so by interannual variation in cyst depositional history. This is due to the relatively low sedimentation rate at the study site compared to the rate of bioturbation, and the fact that the number of cysts deposited each year tends to be a small fraction of the total inventory. Seasonal and interannual variation in cyst deposition strongly influenced concentrations of cysts in the top few millimeters of the sediment, however. When cyst deposition rates are low, bioturbation and germination are sufficient to rapidly deplete cysts in this surface layer, leaving relatively few cysts within the sediment depth range that allows germination. But, bioturbation is not rapid enough to homogenize surface sediments within one year. As a result, cyst deposition results in a concentration peak at the sediment surface that persists to fuel germination the following year. Because of this phenomenon, the model predicted that years with high rates of germination follow years with large levels of cyst deposition. Over longer time scales, bioturbation transports cysts from the sediment surface to depth, which, along with germination, creates a persistent subsurface maximum in cyst concentration. Bioturbation also serves to maintain persistence of A. fundyense by transporting older cysts from these deeper layers to the sediment surface where they can germinate. Since high concentrations of cysts near the sediment surface indicate large numbers of cysts deposited during the previous year, if enhanced germination leads to large blooms of A. fundyense, these blooms are predicted to occur in years following large cyst deposition events.

Georges Bank: A leaky incubator of <i>Alexandrium fundyense</i> blooms	DEEP-SEA RESEARCH PART II-TOPICAL STUDIES IN OCEANOGRAPHY			English	Article						Phytoplankton; Population dynamics; Red tides; Paralytic shellfish poisoning; USA; Gulf of Maine; Georges Bank	SCALLOPS PLACOPECTEN-MAGELLANICUS; NORTHEASTERN UNITED-STATES; PARALYTIC SHELLFISH POISON; INTERANNUAL VARIABILITY; MAINE; GULF; DYNAMICS; POPULATIONS; TOXICITY; MODEL	A series of oceanographic surveys on Georges Bank document variability of populations of the toxic dinoflagellate Alexandrium fundyense on time scales ranging from synoptic to seasonal to interannual. Blooms of A. fundyense on Georges Bank can reach concentrations on the order of 104 cells l(-1), and are generally bank-wide in extent. Georges Bank populations of A. fundyense appear to be quasi-independent of those in the adjacent coastal Gulf of Maine, insofar as they occupy a hydrographic niche that is colder and saltier than their coastal counterparts. In contrast to coastal populations that rely on abundant resting cysts for bloom initiation, very few cysts are present in the sediments on Georges Bank. Bloom dynamics must therefore be largely controlled by the balance between growth and mortality processes, which are at present largely unknown for this population. Based on correlations between cell abundance and nutrient distributions, ammonium appears to be an important source of nitrogen for A. fundyense blooms on Georges Bank. (C) 2012 Elsevier Ltd.

The cold-adapted freshwater dinoflagellate Peridinium aciculiferum has overcome these barriers, often causing blooms in winter but forming resting cysts in spring. Little is known of the biochemical changes that accompany this temperature-induced transformation from vegetative cells to resting cysts. We investigated how the profiles of lipids and mycosporine-like amino acids (MAAs) vary with temperature in vegetative cells and resting cysts of P.aciculiferum. The freshwater dinoflagellate was grown at four temperatures (2.7-7.7 degrees C), simulating the seasonal changes from winter to spring that also induce the transition from cells to cysts. Biochemical profiles were established by liquid chromatography/mass spectrometry with the simultaneous detection of polar and non-polar compounds. Data were analysed by non-metric multidimensional scaling and ANOVA. Over 100 species of galactolipids, betaine lipids, phospholipids and triacylglycerols (TAGs) were found, and many were strong biomarkers for specific temperatures and life stage. Variations in galactolipids, betaine lipids and phospholipids were unidirectional, as shown by an overall decrease in the unsaturation index with temperature. In contrast, changes in TAGs were specific to life stages: short-chain TAGs (cumulative acyl length of 44-52 carbon atoms) decreased in cysts with respect to vegetative cells, while long-chain TAGs (54-62) showed the opposite pattern. The concentration of MAAs decreased with increasing temperature. Final cell yield, a measure of population fitness, also decreased with increasing temperature, confirming the psychrophilic status of P.aciculiferum. We report the first detailed biochemical profiles of vegetative cells and resting cysts for a dinoflagellate and show how small-scale temperature variations alter the biochemical make-up within and between life stages, thus contributing to our understanding of seasonal succession of species.

This organism is also responsible for the production of the neurotoxic compounds known as brevetoxins. Ingestion or inhalation of the brevetoxins leads to adverse effects such as gastrointestinal maladies and bronchoconstriction. Brevenal shows antagonistic behavior to the brevetoxins and shows beneficial attributes when administered alone. For example, in an asthmatic sheep model, brevenal has been shown to increase tracheal mucosal velocity, an attribute which has led to its development as a potential treatment for Cystic Fibrosis. The mechanism of action of brevenal is poorly understood and the exact binding site has not been elucidated. In an attempt to further understand the mechanism of action of brevenal and potentially develop a second generation drug candidate, a series of brevenal derivatives were prepared through modification of the aldehyde moiety. These derivatives include aliphatic, aromatic and heteroaromatic hydrazide derivatives. The brevenal derivatives were tested using in vitro synaptosome binding assays to determine the ability of the compounds to displace brevetoxin and brevenal from their native receptors. A sheep inhalation model was used to determine if instillation of the brevenal derivatives resulted in bronchoconstriction. Only small modifications were tolerated, with larger moieties leading to loss of affinity for the brevenal receptor and bronchoconstriction in the sheep model.

Cultures of O. cf. ovata were performed using both replete and N-free growth media and analyzed for 5 months. Ostreopsis cells displayed a high morphological variability. Some cells were characterized by the presence of orange accumulation bodies, which represented a signal of stress conditions. Two mechanisms of gamete mating seem to occur. In the first (already reported) vegetative cells conjugated through the epitheca without plasmogamy; in this regard we observed a new 'process' on the top of the epitheca which might represent a structure involved in this mating mechanism. In the second, small cells acting as gametes were aligned laterally with the two cingula perpendicular to each other. Meiosis possibly occurred as suggested by tetrad formation, originating four vegetative cells. At least two types of cyst were formed, a non-dormant (pellicle) cyst germinating within 2 days and a resting cyst which is able to germinate after a 5-month dormancy only at temperatures over 25 degrees C.

RESTING CYSTS; TOXIC DINOFLAGELLATE; VERTICAL-DISTRIBUTION; SURFACE SEDIMENTS; HIROSHIMA BAY; BENTHIC CYSTS; A.-CATENELLA; TAMARENSE; DINOPHYCEAE	The tsunami caused by the Great East Japan Earthquake on 11 March 2011 greatly influenced the coastal benthic environment on the northern Pacific coast of Japan. We used the direct count method to investigate changes in the abundance and distribution of Alexandrium (Alexandrium tamarense and Alexandrium catenella) cysts before and after the tsunami in Sendai Bay. Densities of Alexandrium cysts in sediments collected in summer 2011 ranged from 0 to 8,190 cysts cm(-3). In the western part of the bay, the density increased greatly after the tsunami, the highest density being approximately 10 times the density recorded in 2005. Molecular identification of single cysts with multiplex polymerase chain reaction (PCR) showed that Alexandrium tamarense dominated the cyst population in the southwestern part of the bay in 2011. Furthermore, accumulation of cysts on the surface sediment after disturbance of the sediment was confirmed by a laboratory experiment. The main factor causing the drastic changes in abundance and distribution of Alexandrium cysts after the earthquake was considered to be vertical and horizontal redistribution of the cysts in sediments after the tsunami.

Differences in the chemical composition of organic-walled dinoflagellate resting cysts from phototrophic and heterotrophic dinoflagellates	JOURNAL OF PHYCOLOGY			English	Article						phototrophic; heterotrophic; nutritional strategy; dinosporin; dinoflagellate cyst; infrared spectroscopy; macromolecule	SURFACE SEDIMENTS; THECA RELATIONSHIP; UPWELLING SYSTEM; FEEDING-BEHAVIOR; GROWTH-RATES; CELL-WALL; TEMPERATURE; SALINITY; CHITIN; MACROMOLECULES	Dinoflagellates constitute a large proportion of the planktonic biomass from marine to freshwater environments. Some species produce a preservable organic-walled resting cyst (dinocyst) during the sexual phase of their life cycle that is an important link between the organisms, the environment in which their parent motile theca grew, and the sedimentary record. Despite their abundance and widespread usage as proxy indicators for environmental conditions, there is a lack of knowledge regarding the dinocyst wall chemical composition. It is likely that numerous factors, including phylogeny and life strategy, determine the cyst wall chemistry. However, the extent to which this composition varies based on inherent (phylogenetic) or variable (ecological) factors has not been studied. To address this, we used micro-Fourier transform infrared spectroscopy to analyze nine cyst species produced by either phototrophic or heterotrophic dinoflagellates from the extant orders Gonyaulacales, Gymnodiniales, and Peridiniales. Based on the presence of characteristic functional groups, two significantly different cyst wall compositions are observed that correspond to the dinoflagellate's nutritional strategy. The dinocyst wall compositions analyzed appeared carbohydrate-based, but the cyst wall produced by phototrophic dinoflagellates suggested a cellulose-like glucan, while heterotrophic forms produced a nitrogen-rich glycan. This constitutes the first empirical evidence nutritional strategy is related to different dinocyst wall chemistries. Our results indicated phylogeny was less important for predicting composition than the nutritional strategy of the dinoflagellate, suggesting potential for cyst wall chemistry to infer past nutritional strategies of extinct taxa preserved in the sedimentary record.

Here, we investigate their temporal and spatial distribution in the southwest Yatsushiro Sea during the summer of 2011, by co-culturing bacterial isolates with an axenic culture of a fish-killing raphidophyte Chattonella antiqua. This novel co-culturing method excludes other biological influences, such as promotion of algal growth by some bacteria. The highest density (1.6 x 10(4) cells mL(-1)) of algicidal bacteria (AB) was detected at the surface of the nearshore station on 3 August 2011 when the maximum chlorophyll a concentration was observed, associated with the high abundance of two centric diatoms, low abundance of dinoflagellates and the absence of C. antiqua. On 10 August, total bacterial abundance increased at 10 m, suggesting that the bacteria used decaying organic matter derived from dead microalgae sinking to the bottom to promote their growth. Most of AB (87.5%) were found to be particle associated, suggesting these bacteria attached to the dead phytoplankton particles after killing them. Two types of GIB impaired co-cultured C. antiqua by inducing unusual cell deformations, including round and elongated cell morphologies. Partial 16S rRNA sequencing showed that algicidal and GIB were mainly comprised of "gamma- and a-proteobacteria". This study provides a new perspective on the dynamics of AB, suggesting that they play a significant role in regulating microalgal composition, physiology and abundance in coastal marine environments.

Fifteen genera with 26 species were identified from the two cores with total cyst abundance ranging from 138 to 1296 cysts [g-1] [s2] dry wt. Protoperidinium spp. cysts contributed a maximum of 43% to the total cysts, followed by Alexandrium spp. 21% and Diplopsalis cysts with 13%. During this study, six cyst genera with thirteen heterotrophic dinoflagellate species were identified with cyst concentration ranging from 12 to 820 cyst [g-1] [s3] dry wt. Total heterotrophic cyst showed a significant positive correlation with diatoms, sedimentary TP and TN, indicating that increase in diatoms and nutrient concentrations are the main cause of heterotrophic dinoflagellate.

J	Wyatt, T; Zingone, A				Wyatt, Timothy; Zingone, Adriana			Population dynamics of red tide dinoflagellates	DEEP-SEA RESEARCH PART II-TOPICAL STUDIES IN OCEANOGRAPHY			English	Article						Red tides; Harmful algal blooms; Growth; Reproduction	RESTING CYSTS; LIFE-HISTORY; BLOOMS; PATTERNS; PLANKTON; DISTRIBUTIONS; REPRODUCTION; DINOPHYCEAE; MIXOTROPHY; EVOLUTION	Sea-surface discolorations due to high concentrations of phytoplankton are called red tides. Their ecological significance is a long standing puzzle, and they are sometimes considered pathological. Here we propose that many red tides, particularly but not exclusively those composed of certain autotrophic dinoflagellates, are presexual/sexual swarms, essential links in their complex life cycles. This view provides a rationale for the appearance of these organisms in thin surface layers, and helps explain their ephemeral nature. We suggest that further understanding of this phenomenon, and of phytoplankton ecology in general, would benefit from attention to the 'net reproductive value' (r) over the whole life cycle as well as to the division rate (mu) of the vegetative phase. It is argued that r is strategically adapted to seasonal cycles and long term environmental variability, while mu reflects tactical needs (timing) and constraints (grazers, parasites) on vegetative growth.

A total of 40 dinoflagellate cyst types were identified and recorded in the range of 34 and 31532 cyst g(-1) d.wt. in the sediments. The concentration of Lingulodinium machaerophorum, Polykrikos kofoidil, Quinquecuspis concreta, Dubridinium caperatum and Spiniferites bulloideus cysts dominated over other species. Although cysts of potentially toxic species of Alexandrium affine type and A. catenelleamarense complex were found only in Izmir Bay. A. minutum type, Lingulodinium machaerophorum and Operculodinium centrocarpum were observed in the surface sediments of Marmara Sea and Fethiye Bay. The present study provides a database on the distribution and composition of dinoflagellate cysts in the Eastern Mediterranean sea coastal waters of Turkey where modern dinoflagellate cysts have been little studied.

Significant concentrations of toxins were confirmed in all tested samples collected from the western coast of Istria Peninsula (Adriatic Sea, Croatia) when six people were poisoned following the consumption of fresh ascidians. Several species of bivalves that were under continuous monitoring had not accumulated PSP toxins although they were exposed to the same environmental conditions over the survey period. In the present study, HPLC-FLD with pre-column oxidation of PSP toxins has been carried out to provide evidence for the first human intoxication due to consumption of PSP toxic ascidians (Microcosmus vulgaris, Heller, 1877) harvested from the Adriatic Sea. Qualitative analysis established the presence of six PSP toxins: saxitoxin (SIX), decarbamoylsaxitoxin (dcSTX), gonyautoxins 2 and 3 (GTX2,3), decarbamoylgonyautoxins 2 and 3 (dcGTX2,3), gonyautoxin 5 (GTX5) and N-sulfocarbamoylgonyautoxins 1 and 2 (C1,2), while quantitative analysis suggested SIX and GTX2,3 as dominant toxin types and the ones that contribute the most to the overall toxicity of these samples with concentrations near the regulatory limit.

We found growth-inhibiting bacteria (strains E8 and E9) from Zostera marina possessing strong activity against the toxic dinoflagellate Alexandrium tamarense. Strain E9 markedly inhibited growth of A. tamarense even with initial inoculum size as small as 2.9 cells ml(-1). This bacterium also had growth-inhibiting effects on the red-tide raphidophytes Chattonella antiqua and Heterosigma akashiwo, the dinoflagellate Heterocapsa circularisquama, and the diatom Chaetoceros mitra. Small subunit (SSU) ribosomal DNA (rDNA) sequencing analysis demonstrated that the most probable affiliation of these strains was Flavobacteriaceae, and proved that another inhibitory bacterial strain (E8) was the same species as strain E9. Two other bacterial strains (E4-2 and E10), showing different colony color and isolated from the same seagrass sample, revealed no growth-inhibiting activity. Interestingly, strain E4-2 showed the same sequences as E8 and E9 (100 %), and strain E10 matched E8 and E9 with 99.80 % similarity. Growth-inhibiting bacteria against the toxic dinoflagellate Alexandrium tamarense associated with seagrass, such as Flavobacterium spp. E8 and E9, are able to repress shellfish poisoning besides the allelopathic activity of seagrass itself.

Results from Peski, eastern Baltic show the initiation of marine conditions just before 131 ka in the latest Saalian, after the opening of a connection to the North Sea. Following the onset of the Eemian marine highstand and the opening of the White Sea connection at around 130.25 ka, near-fully marine conditions persisted in the eastern Baltic area for ca 6 kyr, until ca 124 ka. For most of the Eemian, a strong thermal stratification in the eastern Baltic resulted from an Arctic and possible North Atlantic water component from the White Sea merging with warmer waters from the North Sea. From ca 124 ka, decreasing salinity indicates the end of the marine highstand and a simultaneous closure of the Baltic Sea-White Sea connection, i.e. a duration of ca 6 kyr for this seaway. The main influence of White Sea inflow appears to be restricted to the eastern Baltic area, although a large submerged area in the Russian Karelia associated with temperate Atlantic waters could have assisted in creating a more oceanic climate for Central Europe.

NOV; PISCICIDA DINOPHYCEAE; STOECKERIA-ALGICIDA; MICROPREDATION; PHYLOGENY	Fish kills in two geographically separate fish farms in northern Denmark in 2012, one using marine, the other brackish water 'Recirculation Aquaculture Systems' (RAS), were found to be caused by Pfiesteria shumwayae and Luciella masanensis, two species of dinoflagellates belonging to the family Pfiesteriaceae. There were no other harmful algae present in either of the aquaculture plants. Serious fish kills in the US have been attributed to Pfiesteria during the past 20 years, but this type of mortality has not been documented elsewhere. L. masanensis, described recently from Korea and USA, has not been previously reported to be the source of fish kills. In the marine farm, the affected fish was rainbow trout, in the brackish water farm pikeperch. Light microscopy is presently insufficient to discriminate between the approx. 20 species of the family Pfiesteriaceae described. Identification of the two algal species was therefore based on molecular sequencing of nuclear-encoded LSU rDNA, confirmed by scanning electron microscopy and, eventually, also by examination of the very thin amphiesmal plates of the flagellates by calcofluor-stained cells in a fluorescence microscope. Although the two fish farms differed in light and salinity conditions, both farms used re-circulating water in closed circuit systems. The dinoflagellates were examined in detail and shown to feed on organic material such as live, damaged nematodes, as described for the single pfiesteriacean flagellate known from freshwater, Tyrannodinium edax. Algal cells were observed to attach to their prey by an attachment filament and subsequently used a peduncle to suck up the food. Fish farms utilizing water recirculation technology are gaining popularity due to their reduced effect on the environment. The two cases from Denmark are apparently the first RAS farms in which serious fish kills have been reported. In the marine farm (Luciella) fish mortality increased dramatically despite treatment of the water with peracetic acid and chloramine-T. The plant was temporarily closed down pending investigation into the cause of mortality and subsequently to determine a method of management to control the dinoflagellate and avoid future fish kills. In the brackish water farm (Pfiesteria), water was treated with chloramine-T, which caused the dinoflagellates to disappear temporarily from the water column, apparently forming temporary cysts. The treatment was repeated after a few days to a week, when the temporary cysts appeared to germinate and the dinoflagellates reappeared in the water column. (C) 2013 Elsevier B.V.

Evaluation of the grazer-prey interaction as a biotechnological strategy to increase toxin production by dinoflagellate cultures in photobioreactors	JOURNAL OF APPLIED PHYCOLOGY			English	Article						Dinoflagellate; Protoceratium reticulatum; Artemia salina; Grazers; Yessotoxins; Photobioreactor	PROROCENTRUM-LIMA; ARTEMIA; ALEXANDRIUM; MICROALGA; COPEPODS; RATES	In this paper, we extend an existing approach to biotechnologically assess grazer-prey interactions between the crustacean Artemia salina (grazer) and the toxic dinoflagellate Protoceratium reticulatum (prey). The applied strategy is presented as a bioprocessing tool for enhancing the production of toxins and bioactive compounds in dinoflagellate cultures. Interactions were based on direct and indirect contact between the grazer and the prey, as well as on the use of different extracts from A. salina cysts and supernatants from cultures in which A. salina had been grown. Several treatments were found to stimulate the growth and yessotoxin production of P. reticulatum mainly due to the action of dissolved excreted substances and/or metabolites released and/or extracted from A. salina. One of the best results was obtained with a culture medium formulation containing 10 % (v/v) supernatant from a culture of A. salina nauplii. This treatment was scaled up to a 15-L photobioreactor. The average maximum specific growth rate (mu (max)) of P. reticulatum in this photobioreactor, operated in batch mode, increased by 27 %, whereas the maximum cell concentration (C (max)) decreased by 20 % relative to the corresponding control culture. An average increase in yessotoxin production of 50 % with respect to the control culture was observed.	[Lopez-Rosales, L.; Gallardo-Rodriguez, J.

Spatiotemporal changes in the genetic diversity of harmful algal blooms caused by the toxic dinoflagellate <i>Alexandrium minutum</i>	MOLECULAR ECOLOGY			English	Article						bloom dynamics; clonality; linkage disequilibrium; population genetics; resting cyst; sexual reproduction	MICROSATELLITE MARKERS; CLONAL DIVERSITY; LIFE-HISTORY; SPRING BLOOM; POPULATION; DINOPHYCEAE; SEX; DIFFERENTIATION; BIOGEOGRAPHY; TEMPERATURE	Organisms with sexual and asexual reproductive systems benefit from both types of reproduction. Sexual recombination generates new combinations of alleles, whereas clonality favours the spread of the fittest genotype through the entire population. Therefore, the rate of sexual vs. clonal reproduction has a major influence on the demography and genetic structure of natural populations. We addressed the effect of reproductive system on populations of the dinoflagellate Alexandrium minutum. More specifically, we monitored the spatiotemporal genetic diversity during and between bloom events in two estuaries separated by 150km for two consecutive years. An analysis of population genetic patterns using microsatellite markers revealed surprisingly high genotypic and genetic diversity. Moreover, there was significant spatial and temporal genetic differentiation during and between bloom events. Our results demonstrate that (i) interannual genetic differentiation can be very high, (ii) estuaries are partially isolated during bloom events and (iii) genetic diversity can change rapidly during a bloom event. This rapid genetic change may reflect selective effects that are nevertheless not strong enough to reduce allelic diversity. Thus, sexual reproduction and/or migration may regularly erase any genetic structure produced within estuaries during a bloom event.

J	Roy, S; Letourneau, L; Morse, D				Roy, Sougata; Letourneau, Louis; Morse, David			Cold-Induced Cysts of the Photosynthetic Dinoflagellate <i>Lingulodinium polyedrum</i> Have an Arrested Circadian Bioluminescence Rhythm and Lower Levels of Protein Phosphorylation	PLANT PHYSIOLOGY			English	Article							TRANSFER RNA-SYNTHETASE; AU-RICH ELEMENTS; MESSENGER-RNAS; PROTEOMIC ANALYSIS; GONYAULAX-TAMARENSIS; TOXIC DINOFLAGELLATE; RESPONSIVE TRANSCRIPTOME; SELECTIVE DEGRADATION; RAPID DEGRADATION; ESCHERICHIA-COLI	Dinoflagellates are microscopic, eukaryotic, and primarily marine plankton. Temporary cyst formation is a well-known physiological response of dinoflagellate cells to environmental stresses. However, the molecular underpinnings of cold-induced cyst physiology have never been described. Cultures of the photosynthetic dinoflagellate Lingulodinium polyedrum readily form temporary cysts when placed at low (8 degrees C +/- 1 degrees C) temperature and excyst to form normal motile cells following a return to normal temperature (18 degrees C +/- 1 degrees C). The normal circadian bioluminescence rhythm and the expected changes in Luciferin Binding Protein abundance were arrested in L. polyedrum cysts. Furthermore, after excystment, the bioluminescence rhythm initiates at a time corresponding to zeitgeber 12, independent of the time when the cells encysted. Phosphoprotein staining after two-dimensional polyacrylamide gel electrophoresis, as well as column-based phosphoprotein enrichment followed by liquid chromatography tandem mass spectrometry, showed cyst proteins are hypophosphorylated when compared with those from motile cells, with the most marked decreases found for predicted Casein Kinase2 target sites. In contrast to the phosphoproteome, the cyst proteome is not markedly different from motile cells, as assessed by two-dimensional polyacrylamide gel electrophoresis. In addition to changes in the phosphoproteome, RNA sequencing revealed that cysts show a significant decrease in the levels of 132 RNAs. Of the 42 RNAs that were identified by sequence analysis, 21 correspond to plastid-encoded gene products and 11 to nuclear-encoded cell wall/plasma membrane components. Our data are consistent with a model in which the highly reduced metabolism in cysts is achieved primarily by alterations in the phosphoproteome. The stalling of the circadian rhythm suggests temporary cysts may provide an interesting model to address the circadian system of dinoflagellates.

Characterization of phytoplankton seed banks in the sediments of a drinking water reservoir	LAKE AND RESERVOIR MANAGEMENT			English	Article						Blooms; cyanobacteria; inocula; pigments; resting stages; sediments	MICROCYSTIS-AERUGINOSA; CYANOBACTERIAL TOXINS; POPULATION-DYNAMICS; ALGAL RECRUITMENT; LAKE-SEDIMENTS; BLOOMS; VARIABILITY; MANAGEMENT; PIGMENTS; COLUMN	The presence, abundance, and composition of algal and cyanobacterial populations in lake sediments were evaluated in Lake St. Charles (Quebec City, Canada), an urban drinking water reservoir. This water body has recently experienced cyanobacterial blooms, and we tested the hypothesis that a seed population of noxious taxa that could potentially re-inoculate the water column was present in the lake sediments. Cores were obtained from 8 sites spanning a range of depth and sediment conditions in both basins of the lake; sampling was from May to October over 2 years. Three techniques were applied: observation of the surficial sediments by epifluorescence microscopy; pigment analysis by high-performance liquid chromatography (HPLC); and laboratory enrichment culture of sediment samples under different light, temperature, and nutrient conditions. These analyses revealed the presence of diverse phytoplankton pigments and fluorescent cells in the sediments, with a predominance of diatoms along with dinoflagellates, chrysophytes, chlorophytes, euglenophytes, and cryptophytes. Growth of benthic filamentous cyanobacteria was induced from the sediments during the incubations, but bloom-forming genera that occurred in the lake such as Anabaena and Microcystis were not detected in any of the sediments, either before or after incubation. These observations imply that the episodic blooms of cyanobacteria in Lake St. Charles were not derived from an abundant seed population distributed throughout the surficial sediments of the lake. Alternative inoculum sources may include localized populations in sediments at sites that were not sampled in the present study, cyanobacteria that may enter via the inflows, or holoplanktonic populations that persist in the water column at low cell concentrations.

J. R. Taylor and their role in bloom dynamics have not yet been adequately characterized and understood. We investigated the role of temperature- and nutrient-mediated stress as factors that could induce pellicle formation in batch cultures. Cellular features and their implications for temporary cyst viability were examined using confocal laser scanning microscopy (CLSM). Our data suggest that temperature change is one of the key factors influencing pellicle formation, preserving viability at low temperature (i.e. 13 degrees C). Hypnocysts (resting cysts) were not observed. During pellicle formation, motile cells generally undergo ecdysis, extrusion of cytoplasmic materials and bacteria, compaction of the nucleus and non-motility. The outermost covering of the temporary cysts shows red autofluorescence and it contains lower concentrations of chlorophyll (chl) a and no detectable chl c. The nuclear region is surrounded by transitional red bodies and other unidentified cellular structures. Temporary cysts can immediately revert back to the motile state upon exposure to optimum conditions. This is accompanied by the expansion of the nuclear region, regeneration of the chloroplasts and enlargement of the cell. Developmental changes during reversal of temporary cysts to motile forms were also observed to cause breaks in the cell covering that could serve as sites for bacterial entry. Though observed in vitro, such behaviour may also be occurring in nature especially as a response to drastic short-lived environmental changes. This is the first detailed report on the characteristics of temporary cysts of P. bahamense var. compressum.

Its distribution appeared very localised and atypical, as it was abundant in the open waters of a cyclonic eddy. Microscope counts of the natural phytoplankton assemblages revealed that F. japonica was dominant in the microplankton, together with Dinophyceae, within and below the cyclonic nutrient-rich dome (25 - 30 m). Bacillariophyceae were the primary microplanktonic fraction in only a few samples on the edges of the eddy. Moderately high abundances of F. japonica (maximum of 60 cells ml(-1)), with preliminary cysts and many cells aggregated in mucous nets, indicated a senescent phase. Despite the Atlantic origin of the cyclonic water masses, the molecular identification and the water temperature of 15 degrees C, which could have favoured pre-cyst formation, would suggest a Mediterranean source for F. japonica cells. Finally, we hypothesise that F. japonica, which is generally a coastal species, could have a coastal origin. In fact, F. japonica was mainly detected at a depth of 40-60 m at the coastal sites and at 25-30 m at the cyclonic dome. F. japonica generally being a coastal species, it can be hypothesised that it was entrapped by the cyclonic eddy, which typically detaches from the coastal waters, and thus carried offshore to the cyclonic waters.

J	Blanco, EP; Lewis, J				Blanco, Eva Perez; Lewis, Jane			A comparative study of Alexandrium tamarense cyst distribution in Belfast Lough	EUROPEAN JOURNAL OF PHYCOLOGY			English	Article						Alexandrium tamarense; anthropogenic activity; Belfast Lough; cyst concentration; cyst distribution; sediment disturbance	DINOFLAGELLATE CYSTS; SURFACE SEDIMENTS; RESTING CYSTS; PUGET-SOUND; EUTROPHICATION; GERMINATION; INDICATORS; CATENELLA; GULF; BAY	Alexandrium tamarense is a cyst-forming dinoflagellate that can cause toxicity in shellfish. Belfast Lough, in northeast Ireland, has experienced toxicity events due to the presence of A. tamarense, which are monitored because of shellfish farms in the Lough. Since 1992 anthropogenic influences on the Lough have changed with the introduction of a 'fast cat' ferry service and an increase in mussel farming. In 2002 Belfast Lough was surveyed for A. tamarense cyst distribution in the sediments and the results are compared to a previous cyst survey carried out in the Lough in 1992. Cyst numbers were generally lower in 2002 than in 1992 (t-test, P < 0.01). The highest concentration found in 2002 was 1058 cysts g(-1) dry sediment compared with 3330 in 1992. Although sediment disturbance increased in the period between the surveys and plays a role in cyst distribution, A. tamarense cysts are still present in the seabed of the Lough. These cysts remain an important repository of inoculating cells for A. tamarense blooms that have not been removed by the recent anthropogenic activity in the Lough and therefore the requirement for monitoring remains. Comparisons between cyst counts per volume of wet sediment and per weight of dry sediment were carried out, and although the first is needed for ecological studies allowing a deeper analysis, it is also recommended that cyst counts per dry weight of sediment are always reported for wider comparative purposes.

Qualitative and quantitative reconstructions of surface water characteristics and recent hydrographical changes in the Trondheimsfjord, central Norway	CLIMATE OF THE PAST			English	Article							DINOFLAGELLATE CYST ASSEMBLAGES; NORTHERN NORTH-ATLANTIC; PLANKTONIC-FORAMINIFERA; HIGH-LATITUDES; SEA; SEDIMENTS; INDICATORS; PRODUCTIVITY; TEMPERATURE; PRESERVATION	In the present study we investigated dinocyst assemblages in the Trondheimsfjord over the last 25 to 50 yr from three well-dated multi-cores (Pb-210 and Cs-137) retrieved along the fjord axis. The downcore distribution of the dinocysts is discussed in view of changes in key hydrographic parameters of the surface waters (sea-surface temperatures (SSTs), sea-surface salinities (SSSs), and river discharges) monitored in the fjord. We examine the impact of the North Atlantic Oscillation pattern and of waste water supply from the local industry and agriculture on the fjord ecological state and thus dinocyst species diversity. Our results show that dinocyst production and diversity in the fjord is not evidently affected by human-induced eutrophication. Instead the assemblages appear to be mainly controlled by the NAO-related changes in nutrient availability and the physicochemical characteristics of the surface mixed layer. Still, discharges of major rivers have been modulated since 1985 by the implementation of hydropower plants, which certainly influences the amounts of nutrients supplied to the fjord. The impact, however, is variable according to the local geographical setting, and barely differentiated from natural changes in river run off. We ultimately test the use of the modern analogue technique (MAT) for the reconstruction of winter and summer SSTs and SSSs and annual primary productivity (PP) in this particular fjord setting. The reconstructed data are compared with time series of summer and winter SSTs and SSSs measured at 10m water depth, as well as with mean annual PPs along the Norwegian coast and in Scandinavian fjords. The reconstructions are generally in good agreement with the instrumental measurements and observations from other fjords. Major deviations can be attributed to peculiarities in the assemblages linked to the particular fjord setting and the related hydrological structure.

ENVIRONMENTAL-FACTORS; CRASSOSTREA-GIGAS; RESTING CYSTS; PSP TOXINS; DINOFLAGELLATE; RIVER; DINOPHYCEAE; ESTUARY; JAPAN; ACCUMULATION	A monitoring program for seasonal dynamics of A. tamarense and paralytic shellfish poisoning toxins (PSTs) in bivalves was carried out from April 2006 to March 2007 in Nanji Islands, East China Sea. Low abundances of A. tamarense (fewer than 4.0 x 10(2) cells L-1) were first observed on 15 April 2006. During middle May, blooms of A. tamarense were documented, with the mean density of 3.8 x 10(3) cells L-1 and 0.75 x 10(3) cells L-1, corresponding to surface and bottom water columns, respectively. Environmental conditions of temperature range 18-20 degrees C and salinity range 29.5-31 coincided with a high abundance of A. tamarense in the region, and the bloom collapse was likely to be a response to P limitation. Toxin concentrations in cultured Patinopecten yessoensis, Mytilus galloprovincialis and wild Mytilus coruscus during A. tamarense blooms ranged from 68.9 to 96.3 mu g STXeq per 100 g flesh. Toxin profiles were similar among bivalve shellfish samples, dominated by C1 and C2 in 51.4-64.6 mol% of toxins, with an average of 60.6 mol%, followed by GTX5, GTX1-GTX4, dcGTX2 and dcGTX3. However, from January to March 2007, lower toxin concentrations, 18.9-40.8 mu g STXeq per 100 g were found only in the wild Oyster sp., comprising GTX4, GTX5 and GTX1.

J	Kurokawa, T; Okamura, Y				Kurokawa, Tatsuki; Okamura, Yasushi			Mapping of sites facing aqueous environment of voltage-gated proton channel at resting state: A study with PEGylation protection	BIOCHIMICA ET BIOPHYSICA ACTA-BIOMEMBRANES			English	Article						Ion channel; Proton; Voltage; Membrane potential; Gating; pH	2 PORES; HV1; DOMAIN; DINOFLAGELLATE; COOPERATIVITY; MECHANISM; SENSOR; KV1.3	Hvi (also named, voltage-sensor only protein, VSOP) lacks an authentic pore domain, and its voltage sensor domain plays both roles in voltage sensing and proton permeation. The activities of a proton channel are intrinsic to protomers of Hvl, while Hvl is dimeric in biological membranes; cooperative gating is exerted by interaction between two protomers. As the signature pattern conserved among voltage-gated channels and voltage-sensing phosphatase, Hvl has multiple arginines intervened by two hydrophobic residues on the fourth transmembrane segment, 54. S4 moves upward relative to other helices upon depolarization, causing conformational change possibly leading to the formation of a proton-selective conduction pathway. However, detailed mechanisms of proton-selectivity and gating of fivl are unknown. Here we took an approach of PEGylation protection assay to define residues facing the aqueous environment of mouse Hvl (mHv1). Accessibilities of two maleimide molecules, N-ethylmaleimide (NEM) and 4-acetamido-4'-malehnidylstilbene-2,2'-disulfonic acid (AMS), were examined on cysteine introduced into individual sites. Only the first arginine on S4 (R1: R201) was inaccessible by NEM and AMS in mHvl. This is consistent with previous results of electrophysiology on the resting state channel, suggesting that the accessibility profile represents the resting state of mHvl. 0108, critical for proton selectivity, was accessible by AMS and NEM, suggesting that 0108 faces the vestibule. F146, a site critical for bloddng by a guanidiniumreagent, was accessible by NEM, suggesting that F146 also faces the inner vestibule. These findings suggest an inner vestibule lined by several residues on S2 including F146, D108 on S1, and the C-terminal half of S4. (C) 2013 Elsevier B.V. All rights reserved.

Here we report a new species, Alexandrium diversaporum nov. sp., isolated from spherical cysts found at two sites in Tasmania, Australia. This species differs in its morphology from all previously reported Alexandrium species, possessing a unique combination of morphological features: the presence of 2 size classes of thecal pores on the cell surface, a medium cell size, the size and shape of the 6 '', 1', 2'''' and Sp plates, the lack of a ventral pore, a lack of anterior and posterior connecting pores, and a lack of chain formation. We determined the relationship of the two strains to other species of Alexandrium based on an alignment of concatenated SSU-ITS1, 5.8S, ITS2 and partial LSU ribosomal RNA sequences, and found A. diversaporum to be a sister group to Alexandrium leei with high support. A. leei shares several morphological features, including the relative size and shapes of the 6 '', 1', 2'''' and Sp plates and the fact that some strains of A. leei have two size classes of thecal pores. We examined A. diversaporum strains for saxitoxin production and found them to be non-toxic. The species lacked sequences for the domain A4 of sxtA, as has been previously found for non-saxitoxin producing species of Alexandrium. (C) 2013 Elsevier B.V. All rights reserved.

The dynamics of these blooms have been studied since 2003, and a high degree of inter-annual variability in the cell densities has been observed. Two intense blooms, with maximum cell densities >500,000 cells L-1, were observed in the summers of 2004 and 2011. Annual cyst surveys during winter found that cyst densities decreased after the 2004 bloom, and by 2010 an average of ca. 40 cysts g dry wt sediment(-1) was recorded. The intensity of blooms was found to be independent of the cyst density measured the previous winter. The cyst input to the sediment during both intense and low density blooms was measured directly through the deployment of sediment traps in the North Channel. The data allowed an estimate of the proportion of the A. minutum vegetative cells that underwent successful encystment, which averaged at 2.5% across a range of cell densities spanning three orders of magnitude. Maturation times of fresh cysts were determined at 5, 10 and 15 degrees C. The maturation time at 15 degrees C was found to be approximately 5 months, a value which increased by two months for a 5 degrees decrease in temperature. A cyst dynamics model was constructed based on the field data to simulate the temporal variation of A. minutum cysts in the oxic layer of sediment. It revealed that a degree of resuspension is required to prevent cyst stocks from becoming exhausted in the thin oxic layer at the surface of the sediment. The model also demonstrated that the cysts supplied by periodic intense blooms, which occur with a frequency of every 7-8 years, are not in themselves enough to allow the population to persist over long time scales (decades). The cyst input from interim blooms of lower density is however enough to ensure the annual inoculation of the water column with A. minutum cells. (C) 2013 Elsevier B.V. All rights reserved.

Studies on woloszynskioid dinoflagellates VI: description of <i>Tovellia aveirensis</i> sp nov (Dinophyceae), a new species of Tovelliaceae with spiny cysts	EUROPEAN JOURNAL OF PHYCOLOGY			English	Article						cyst; dinoflagellates; LSU rDNA; phylogeny; taxonomy; Tovelliaceae; Tovellia aveirensis; ultrastructure	LAKE TOVEL; ELECTRON-MICROSCOPY; RDNA SEQUENCES; GEN. NOV.; LSU; ULTRASTRUCTURE; PHYLOGENY; EVOLUTION; GENERA; LIGHT	A new species of Tovellia, T. aveirensis, is described on the basis of light (LM) and scanning electron microscopy (SEM) of motile cells and resting cysts, complemented with transmission electron microscopy (TEM) of flagellate cells and phylogenetic analysis of partial sequences of the large subunit ribosomal rRNA gene. Both vegetative cells and several stages of a life cycle involving sexual reproduction and the production of resting cysts were examined in cultures established from a tank in the University of Aveiro campus. Vegetative cells were round and little compressed dorsoventrally; planozygotes were longer and had a proportionally larger epicone. Chloroplast lobes were shown by TEM to radiate from a central, branched pyrenoid, although this was difficult to ascertain in LM. The amphiesma of flagellate cells had mainly 5 or 6-sided vesicles with thin plates, arranged in 5-7 latitudinal series on the epicone, 3-5 on the hypocone. The cingulum had 2 rows of plates, the posterior row extending into the hypocone and crossed by a series of small projecting knobs along the lower edge of the cingulum. A line of narrow amphiesmal plates extended over the cell apex, from near the cingulum on the ventral side to the middle of the dorsal side of the epicone. Eight or 9 narrow amphiesmal plates lined each side of this apical line of plates (ALP). Resting cysts differed from any described before in having numerous long, tapering spines with branched tips distributed over most of the surface. Most mature cysts showed an equatorial constriction. Neither cysts nor motile cells were seen to accumulate red cytoplasmic bodies in any stage of the cultures. The phylogenetic analysis placed, with high statistical support, the new species within the genus Tovellia; it formed a clade, with moderate support, with T. sanguinea, a species notable for its reddening cells.

Usually A. ostenfeldii occurs in low background concentrations only, but in August of 2012 an exceptionally dense bloom of more than 1 million cells L-1 occurred in the brackish Ouwerkerkse Kreek in The Netherlands. The A. ostenfeldii bloom produced both saxitoxins and spirolides, and is held responsible for the death of a dog with a high saxitoxin stomach content. The Ouwerkerkse Kreek routinely discharges its water into the adjacent Oosterschelde estuary, and an immediate reduction of the bloom was required to avoid contamination of extensive shellfish grounds. Previously, treatment of infected waters with hydrogen peroxide (H2O2) successfully suppressed cyanobacterial blooms in lakes. Therefore, we adapted this treatment to eradicate the Alexandrium bloom using a three-step approach. First, we investigated the required H2O2 dosage in laboratory experiments with A. ostenfeldii. Second, we tested the method in a small, isolated canal adjacent to the Ouwerkerkse Kreek. Finally, we brought 50 mg L-1 of H2O2 into the entire creek system with a special device, called a water harrow, for optimal dispersal of the added H2O2. Concentrations of both vegetative cells and pellicle cysts declined by 99.8% within 48 h, and PSP toxin concentrations in the water were reduced below local regulatory levels of 15 mu g L-1. Zooplankton were strongly affected by the H2O2 treatment, but impacts on macroinvertebrates and fish were minimal. A key advantage of this method is that the added H2O2 decays to water and oxygen within a few days, which enables rapid recovery of the system after the treatment. This is the first successful field application of H2O2 to suppress a marine harmful algal bloom, although Alexandrium spp. reoccurred at lower concentrations in the following year. The results show that H2O2 treatment provides an effective emergency management option to mitigate toxic Alexandrium blooms, especially when immediate action is required. (C) 2013 Elsevier B.V.

Surface sediment dinoflagellate cysts from the Hudson Bay system and their relation to freshwater and nutrient cycling	MARINE MICROPALEONTOLOGY			English	Article						Dinoflagellate cysts; Hudson Bay; Sediment; Sea-ice; Biogenic silica; Nitrogen; Lignin	ORGANIC-WALLED MICROFOSSILS; PROCESS LENGTH VARIATION; NORTHERN NORTH-ATLANTIC; SEA-ICE; ARCTIC-OCEAN; MARINE-SEDIMENTS; CLIMATE-CHANGE; PROTOCERATIUM-RETICULATUM; PHYTOPLANKTON GROWTH; SCRIPPSIELLA-HANGOEI	Surface sediment samples from the Hudson Bay system were analysed in order to examine the role of key regulators of arctic marine productivity light and nutrients as affected by freshwater stratification and sea-ice cover on the spatial distribution and production of dinoflagellate cysts. Total cyst fluxes vary from 0.2 x 10(6) to 30.6 x 106 cysts m(-2) a(-1), with the highest values observed in eastern Hudson Bay. A total of 24 cyst taxa, representing 11 genera of five orders, were identified and distribution maps of the most common taxa have been produced. This is the first record of Echinidinium aculeatum, Echinidinium karaense, cf. Echinidinium delicatum, Islandinium brevispinosum, Selenopemphix quanta, cysts of Protoperidinium americanum, cysts of cf. Biecheleria sp. and Polarella glacialis in the Hudson Bay system. Dinoflagellate cyst assemblages show distinct spatial patterns revealing three compositional domains: eastern Hudson Bay, western-central Hudson Bay and Hudson Strait. The eastern domain is characterised by a dominance of autotrophic cysts of Pentapharsodinium dalei whereas the western-central domain is characterised by autotrophic Operculodinium centrocarpum with some contribution by heterotrophic Polykrikos sp. var. arctic morphotype and Polykrikos spp. Sites from Hudson Strait are distinguished by an overwhelming prevalence of heterotrophic Protoperidiniaceae cysts, mainly Islandinium minutum, and have the highest values of sedimentary biogenic silica, used as a proxy for diatom productivity. Sediment geochemical tracers are used as proxies for freshwater inputs (lignin and its biomarkers) and nitrate availability (nitrogen isotopes), and sea-ice concentrations derived from passive microwave data as a proxy for light availability. Sea-ice regulated length of the dark season has a negligible influence on the proportion and production of heterotrophic (dark-adapted) versus autotrophic (light-dependent) dinoflagellate cysts, perhaps due to the location of our study area on the southern fringe of the Arctic. Instead, cyst populations in Hudson Bay are primarily regulated by vertical stratification and nitrate availability, while in Hudson Strait the pivotal mechanism constitutes food availability.

They are fast-acting and highly toxic when administered in vivo in rodent bioassays, causing death by respiratory depression within minutes. Studies have revealed that some cyclic imine toxins cause their toxicity by antagonizing both muscle type and heteromeric and homomeric neuronal nicotinic acetylcholine receptors (nAChRs). Pinnatoxins E, F and G all display potent toxicity in in vivo bioassays, with symptoms of toxicity similar to other cyclic imine toxins. However, very little work has been done on the mechanism of action of these pinnatoxin isomers. Thus the aim of the current study was to investigate the rank order of potency and mechanism of action of pinnatoxins E, F and G. The effects of pinnatoxin E, F and G on in vitro rat hemidiaphragm preparations were investigated using twitch tension and electrophysiological techniques to determine the effects of these toxins on cholinergic transmission at the neuromuscular junction. Pinnatoxins E, F and G all produced concentration-dependent reductions in the nerve evoked twitch response of the rat hemidiaphragm, with IC50 values ranging from 11 to 53 nM and a rank order of potency of F > G > E. Only complete washout of pinnatoxin E was evident, with pinnatoxins F and G displaying slow and incomplete washout profiles. Pinnatoxins F and G also reduced the amplitudes of spontaneous miniature endplate potentials and evoked endplate potentials at the neuromuscular junction, without affecting miniature endplate potential frequency or the resting membrane potential of the muscle fibres. These results show that pinnatoxins E, F and G are all potent neuromuscular blocking agents and cause toxicity by acting as antagonists at muscle type nicotinic acetylcholine receptors.

However, previous studies revealed that there are morphological and genetic differences among Crypthedodinium cohnii-like strains, indicating the potential of undiscovered diversity of this dinoflagellate. Attempts of isolating heterotrophic marine dinoflagellate strains were made from submerged mangrove leaves and seaweed. A total of nine strains were established, cultured and maintained using seawater-based GTY medium for taxonomic identification and phylogenetic analyses based on SSU, ITS 1, 5.8S, ITS2 and LSU rDNA. Morphological observation revealed all strains shared similar morphology, e.g.: motile cells were delicately thin armored with single or double flagella surrounding the cingulum and protruding along the sulcus posteriorly, while non-motile cell stage (cyst) may retain more than two daughter cells inside the transparent and thick cell wall. Both cell stages varied in sizes and shapes even within the same clonal culture. Numerous lipid granules can be observed in the cytoplasm. Two types of cingulum encirclement were observed: partially or completely surrounding the cell body. All strains indicated close relatedness (>95% sequence similarity) with previously reported Cryphtecodinium cohnii strains, except for C. cohnii CAAE-CL2 (87.2-87.4% similarity) in SSU and C. cohnii CCMP316 (79.9-80.4% similarity) in ITS. Moreover, molecular phylogenetic tree grouped the Okinawan isolates into two genetically distinct clades with high similarity (>98%) among members of each clade in SSU and LSU but only shared 80.5% similarity in ITS rDNA. The results of this study showed evidences of undiscovered diversity in the heterotrophic dinoflagellates currently regarded as Crypthecodinium.

From 2008 to 2010 in the Forge River Estuary, NY, USA, P.hartmannii bloomed during summer and early fall, achieving densities exceeding 8,000 cellsmL(-1) and often dominating microphytoplankton communities. Large subunit (LSU) and small subunit (SSU) rDNA sequences demonstrated that NY isolates of P.hartmannii sequences were 99%-100% identical to P.hartmannii isolates from eastern US and Korea. In both the LSU and SSU rDNA phylogenies, the clades containing P.hartmannii sequences were distinct sister clades to those composed of Polykrikos schwartzii and P.kofoidii. In the LSU rDNA phylogeny, however, the clade composed of P.hartmannii and a sequence of the photosynthetic Polykrikos lebourae was well separated from the clade composed of 10 entries of Polykrikos schwartzii and P.kofoidii. In addition, a gap of similar to 180 bases was observed when the LSU rDNA sequences of P.hartmannii were aligned with P.schwartzii and P.kofoidii but was not observed in the alignment between P.hartmannii and P.lebourae. Using scanning electron microscopy, several morphological features previously not reported for P.hartmannii were observed: a ventral groove located in the sulcus, a deep arc-like apical concavity within the area of apical groove, scale-like vesicles, and a shallow, completely enclosed, loop-like apical groove. Resting cysts with arrow-like surface spines were produced heterothallically by crossing clonal isolates and germinated single gymnoid cells. Finally, filtered and unfiltered bloom water from the Forge River and clonal cultures of P.hartmannii exhibited acute ichthyotoxicity to juvenile sheepshead minnows (Cyprinodon variegates) and aeration did not mitigate this effect, suggesting P.hartmannii is an ichthyotoxic, harmful alga.

DINOPHYCEAE; GEN. NOV.; COASTS; AUSTRALIA; WATERS; OCEAN	During a phytoplankton survey, non-motile (cyst-like) cells were isolated and cultured from the tropical Mexican Pacific, which belong to the thecate dinoflagellate Vulcanodinium rugosum Nezan et Chomerat, recently described from the Mediterranean and recently identified as a source of pinnatoxins in Australia, New Zealand, and Japan. Motile cells and putative cysts were studied by light microscopy and scanning electron microscopy. The most characteristic features of the species agree with a previous description: (i) large and conspicuous apical pore, which extrudes mucilaginous material; (ii) polygonal and striated theca; (iii) ventral, sigmoid canal running from the apical pore to the anterior margin of the cingulum; (iv) three connected anterior intercalary plates; and (v) production of spherical cyst-like cells. The species is photosynthetic, containing many small greenish-brown chloroplasts. The tabulation of the species is Po, X, 4', 3a, 7 '', 6c, 5s?, 5''', 2''''. Organic cyst-like cells were nearly spherical to subspherical, solitary, or aggregations linked by mucilaginous material; they are considered to be a stage in the life cycle of the species. Vulcanodinium rugosum is a new record in the study area. The ecology and the geographical distribution of the species are also discussed.

Provenance of surface sediments along the southeastern Adriatic coast off Italy: An overview	ESTUARINE COASTAL AND SHELF SCIENCE			English	Article						geochemistry; organic matter; grain size; multi-proxy; West Adriatic current (WAC); Adriatic mud belt	WATER CORAL PROVINCE; ORGANIC-MATTER; IONIAN SEA; MEMBRANE-LIPIDS; GULF; SHELF; INDICATORS; PROXIES; MARINE; ORIGIN	Multi-proxy studies are necessary to understand sediment composition and related provenance on continental shelfs. Here it is shown that the spatial distribution of geochemical composition and grain size for surface sediments along the southeastern Italian coast is related to provenance and mechanisms influencing sediment pathways. A northern Adriatic/Italian provenance can be distinguished from a southern Apennine river source. This is done independent of grain size using the element ratios Ce/Ni and Zr/Cr. Furthermore, the origin of organic matter is determined using bulk carbon isotopes and the C/N ratio. Integrating these results with those from complementary studies on delta O-18 and delta C-13 of Globigerinoides ruber (white), the BIT index, stable isotopes of plant waxes and dinoflagellate cyst distribution from the same set of samples reveals that: Sediments from the northwestern Adriatic are transported as far southward as the Gallipoli shelf (eastern Gulf of Taranto) by the Western Adriatic Current (WAC) Along the WAC, there is a consistent southward decrease in Po river/northern Apennines provenance and a concomitant decrease in terrestrial (soil) organic matter (OM), whereas the percentage of marine OM increases. The provenance for Gallipoli shelf sediments is for similar to 80% attributed to Po River/northern Apennines sources and for similar to 20% to southern Italian sources. OM in the eastern Gulf of Taranto contains more marine OM than other areas within the WAC, whereas OM and sediments from the western part of the Gulf of Taranto have a more local, riverine provenance.

Sexual life stages and temperature dependent morphological changes allow cryptic occurrence of the Florida red tide dinoflagellate <i>Karenia brevis</i>	HARMFUL ALGAE			English	Article						Behavior; Bloom; Cryptic; Cyst; Dinoflagellate; Gamete; Karenia brevis; Mating; Morphology; Zygote	GYMNODINIUM-BREVE; CELL-CYCLE; MOLECULAR-DETECTION; DINOPHYCEAE; CYSTS; GULF; TAKAYAMA; BLOOMS; MICROCERATIUM; ASTERODINIUM	Karenia brevis, the Florida red tide dinoflagellate, has been studied extensively, but very little attention has been paid to its sexual life cycle. We found that the life cycle of K. brevis is heterothallic, most probably not resting cyst-producing, but with life stages of different morphology. The isogamous gametes were slightly smaller than vegetative cells and not as broad and flat. The late zygote was yellow-brown in appearance with a thicker wall and more rounded shape lacking carina. Pellicle cysts of these zygotes closely resembled the few earlier descriptions of "possible cysts" of the species. In addition, temperature-dependent, morphological changes and pellicle-cyst formation were observed. Cells placed in the cold (15 degrees C) formed spherical, thin-walled pellicle cysts that germinated into cells that were round in cross-section and longer than wide - so morphologically different from vegetative cells that they would not be correctly identified if encountered in field samples. Cells grown at 25 degrees C were wider and flatter than cells grown at 20 degrees C. Cells warmed from cold conditions became flat and wide within hours, returning to the typical shape. Also the morphological differences between sexual life stages were large enough to allow misidentification and cryptic occurrence of K. brevis. The cell shape of K. brevis was not fixed, but could vary from very wide and flat to elongate with rounded cross-section in the same culture of clonal cells and in the same cells within a short time (hours). In addition to the culture studies, sediment samples from a Karenia "hot spot" area were concentrated, and the dinoflagellate cyst fraction was investigated for resting cysts. Cysts were not found, and Karenia cells did not germinate from slurry cultures of the concentrated cyst fraction. (C) 2013 Elsevier B.V. All rights reserved.

(Dinoflagellata, Protoperidiniaceae) is established by incubating resting cysts from estuarine sediments off southern Vancouver Island, British Columbia, Canada, and San Pedro Harbor, California, USA. The cysts have a brown-coloured wall, and are characterized by a saphopylic archeopyle comprising three apical plates, the apical pore plate and canal plate; and acuminate processes typically arranged in linear clusters. We elucidate the phylogenetic relationship of P. fukuyoi through large and small subunit (LSU and SSU) rDNA sequences, and also report the SSU of the cyst-defined species Islandinium minutum (Harland & Reid) Head etal. 2001. Molecular phylogenetic analysis by SSU rDNA shows that both species are closely related to Protoperidinium americanum (Gran & Braarud 1935) Balech 1974. Large subunit rDNA phylogeny also supports a close relationship between P. fukuyoi and P. americanum. Three subgroups in total are further characterized within the Monovela group. The cyst of P. fukuyoi shows a wide geographical range along the coastal tropical to temperate areas of the North-east Pacific, its distribution reflecting optimal summer sea-surface temperatures of similar to 14-18 degrees C and salinities of 22-34psu.

Cells were small, spherical to slightly elongated, and had a projecting, nearly cylindrical, apical pore. The chloroplasts were yellowish-brown, arranged near the surface of the cell, and had up to four pyrenoids surrounded by starch sheaths. The cells had a peridinioid plate pattern with Kofoidian plate formula pp, cp, x, 3' (seldom 4'), 2a, 7 '', 6c, 5s (6s?), 5 ''', 2 ''''. A small extruded peduncle was observed by SEM in cells with intact membranes. A microtubular basket, made of about 46 microtubules disposed in four rows, was seen in the ventral area in connection with the cytoplasmic extension that made the peduncle. The flagellar apparatus was typical of a peridinioid with two roots associated with each of the basal bodies and a layered connective linking the proximal ends of roots 1 and 4. In dense cultures, this organism produced a round resting cyst with a thick wall covered by irregular calcified elements. Energy dispersive X-ray analysis (EDS) analysis of the cysts showed calcium as the most abundant element. A total of 3048 nucleotides of the nuclear ribosomal operon were sequenced and used in a phylogenetic analysis that placed this organism as a sister group to a clade of Scrippsiella species and the parasitic Duboscquodinium collinii. Theleodinium calcisporum gen. et sp. nov. is described for the first freshwater dinoflagellate reported to produce calcareous cysts.

Chlorine dioxide as a treatment for ballast water to control invasive species: Shipboard testing	MARINE POLLUTION BULLETIN			English	Article						Ballast water; Chlorine dioxide; ClO2; Invasive species; Shipping; Biocide	EURYTEMORA-AFFINIS COPEPODA; VIBRIO-CHOLERAE O1; DINOFLAGELLATE CYSTS; NATURAL-POPULATIONS; DIAPAUSE EGGS; SHIPS; ZOOPLANKTON; SEDIMENTS; EFFICACY; TIME	The efficacy of chlorine dioxide (ClO2) in eliminating organisms present in estuarine ballast water of a containership was determined under actual operating conditions by comparing the survival of planktonic communities present in waters of treated and control ballast tanks. Sampling was via ballast-tank hatches. The treatment (5 mg L-1 ClO2 without pre-filtration) delivered by a prototype ClO2-generating system was generally effective against planktonic assemblages, although bacterial communities rebounded after a few days. Regardless of temperature, ClO2 was very effective against phytoplankton; the effect was immediate, without resurgence. Some zooplankters in the >= 50-mu m fraction may survive the biocide, especially those able to find refuge within a protective coating (e.g., cysts, resting eggs, and shells) or in sediment. In order to boost efficacy, a pre-filtration step is recommended (now installed as standard equipment) to lower the intake of the >= 50-mu m fraction and lessen the challenge posed by this size class.

Disinfection of Ballast Water with Iron Activated Persulfate	ENVIRONMENTAL SCIENCE & TECHNOLOGY			English	Article							TOXIC DINOFLAGELLATE CYSTS; WASTE-WATER; OXIDATION; SHIPS; TRANSPORT; MECHANISM; KINETICS; TRICHLOROETHYLENE; BACILLARIOPHYCEAE; MICROORGANISMS	The treatment of ballast water carried onboard ships is critical to reduce the spread of nonindigenous aquatic organisms that potentially include noxious and harmful taxa. We tested the efficacy of persulfate (peroxydisulfate, S2O82-, PS) activated with zerovalent iron (Fe-0) as a chemical biocide against two taxa of marine phytoplankton grown in bench-scale, batch cultures: the diatom, Pseudonitzshia delicatissima and the green alga, Dunaliella tertiolecta. After testing a range of PS concentrations (0-4 mM activated PS) and exposure times (1-7 days), we determined that a dosage of 4 mM of activated PS was required to inactivate cells from both species, as indicated by reduced or halted growth and a reduction in photosynthetic performance. Longer exposure times were required to fully inactivate D. tertiolecta (7 days) compared to P. delicatissima (5 days). Under these conditions, no recovery was observed upon placing cells from the exposed cultures into fresh media lacking biocide. The results demonstrate that activated PS is an effective chemical biocide against species of marine phytoplankton. The lack of harmful byproducts produced during application makes PS an attractive alternative to other biocides currently in use for ballast water treatments and merits further testing at a larger scale.

Herein we established eight strains by incubating single cysts of Pentapharsodiniumdalei from the Chukchi Sea, Yellow Sea, and South China Sea. The six strains from the Chukchi Sea and Yellow Sea fit the description of P.dalei, and they share identical internal transcribed spacer region (ITS1, ITS2 and 5.8S rDNA) sequences. The two other strains (G96 and PDFC01) from the South China Sea are morphologically similar to P.dalei, but they possess a spine on the anterior sulcal plate and an additional Sm plate. These two strains were described as P.dalei var. aciculiferum. They share identical ITS sequences and differ from P.dalei strains PDCH01 (Yellow Sea) and SZN19 (Norway origin) at 20 and 26 positions (96.40% and 95.32% similarity) respectively. Maximum-likelihood and Bayesian inference resolved a well supported clade consisting of P.dalei and P.dalei var. aciculiferum. Our results reveal that cysts of P.dalei might comprise several morphologically, genetically, and ecologically different varieties.

This species was exposed to increasing concentrations of Cu2+ (9.93 x 10(-10)-1.00 x 10(-7) M) or Cd2+ (1.30 x 10(-8)-4.38 x 10(-7) M), to simulate polluted environments. The drastic effects were observed at pCu(2+) = 7.96 (Cu2+: 1.08 x 10(-8) M) and pCd(2+) = 7.28 (Cd2+: 5.19 x 10(-8) M), where cyst formation occurred. Lower levels of Cu2+ (pCu(2+) > 9.00) and Cd2+ (pCd(2+) > 7.28) had no effect on growth. However, when levels of Cu2+ and Cd2+ were beyond 10(-7) M, the growth was totally inhibited. The DOC released per cell (DOC/Cell) was different depending on the exposure time and the metal contamination, with higher DOC/Cell values in response to Cu2+ and Cd2+, comparatively to the control. Samples were also analyzed by 3D-fluorescence spectroscopy, using the Parallel Factor Analysis (PARAFAC) algorithm to characterize the FDOM. The PARAFAC analytical treatment revealed four components (C1, C2, C3 and C4) that could be associated with two contributions: one, related to the biological activity; the other, linked to the decomposition of organic matter. The C1 component combined a tryptophan peak and a characteristic humic substances response, and the C2 component was considered as a tryptophan protein fluorophore. The C3 and C4 components were associated to marine organic matter production. (C) 2013 Elsevier Ltd. All rights reserved.

Toxicity varies among morphologically similar species, and a precise identification is needed for early warning systems. Molecular techniques using ribosomal DNA sequences offer a means to identify and detect precisely the potentially toxic species. We designed molecular probes targeting the 18S rDNA at the family and genus levels for Dinophysis and Phalacroma and at the species level for Dinophysis acuminata, Dinophysis acuta, and Dinophysis norvegica, the most commonly occurring, potentially toxic species of these genera in Western European waters. Dot blot hybridizations with polymerase chain reaction (PCR)-amplified rDNA from 17 microalgae were used to demonstrate probe specificity. The probes were modified along with other published fluorescence in situ hybridization and PCR probes and tested for a microarray platform within the MIDTAL project (http://www.midtal.com). The microarray was applied to field samples from Norway and Spain and compared to microscopic cell counts. These probes may be useful for early warning systems and monitoring and can also be used in population dynamic studies to distinguish species and life cycle stages, such as cysts, and their distribution in time and space.

Twenty-one dinoflagellate cyst taxa were identified, with the assemblages dominated mainly by Spiniferites bulloideus, Operculodinium centrocarpum, and cyst of Alexandrium catenella/tamarense type. A high frequency of O. centrocarpum in the Yellow Sea was observed for the first time, and it is likely that this can be attributed to the dynamics of the Yellow Sea Cold Water Mass and the Changjiang (Yangtze) River runoff. Total cyst concentrations ranged from 23 to 48 442 cysts/g dry weight, and high cyst concentrations were recorded adjacent to the dumping site. This result suggests that anthropogenic activities such as ocean dumping stimulate the growth of dinoflagellates in the Yellow Sea, which in turn leads to high levels of dinoflagellate cyst production.

J	Warns, A; Hense, I; Kremp, A				Warns, Alexandra; Hense, Inga; Kremp, Anke			Encystment of a cold-water dinoflagellate - From in vitro to in silico	JOURNAL OF MARINE SYSTEMS			English	Article						Life cycle; Cyst formation; Seed population; Growth; Dinoflagellates	NORTHERN BALTIC SEA; SCRIPPSIELLA-HANGOEI; CYST FORMATION; RESTING CYSTS; POPULATION-DYNAMICS; SPRING-BLOOM; LIFE-CYCLE; CULTURE; GROWTH; DINOPHYCEAE	Blooms of dinoflagellates are frequently observed in coastal regions. The dynamics of these blooms are strongly affected by life cycle transitions. For example, many species form resting cysts at the end of the growth period that act as a seed population. Despite considerable efforts, one major process of the dinoflagellate life cycle - the encystment - is not fully understood. In this study, we reanalyse a published laboratory data set for the cold-water dinoflagellate Biecheleria baltica and develop a numerical model to study cyst formation. We find significant differences between cell counts and biomass, leading to different conclusions about the encystment process. To accurately reproduce the laboratory data, two mechanisms have to be taken into account in the model: a time lag in cyst formation and a reduction in the growth rate of vegetative cells as soon as cysts are formed. Using this model we are able to identify and formalise the functional dependence among growth, cyst formation, and environmental factors. Our model can serve as a prerequisite for dinoflagellate life cycle models to study the dynamics of bloom formations. (c) 2012 Elsevier B.V. All rights reserved.

Stress-related Responses in <i>Alexandrium tamarense</i> Cells Exposed to Environmental Changes	JOURNAL OF EUKARYOTIC MICROBIOLOGY			English	Article						Apoptosis; caspase-like enzymes; cell cycle; dinoflagellate; metacaspases; physico-chemical challenge; reactive oxygen species; temporary cyst	UNICELLULAR CHLOROPHYTE; TOXIC DINOFLAGELLATE; LEISHMANIA-MAJOR; KARENIA-BREVIS; DEATH; CASPASES; METACASPASES; APOPTOSIS; CYCLE; ADAPTATION	Organisms tend to be sensitive to drastic changes in environmental conditions. For unicellular microorganisms, variations in physico-chemical conditions are particularly challenging and may result in acclimation, entrance into quiescence, or death through necrotic or autocatalytic pathways. This study focuses on the thecate dinoflagellate Alexandrium tamarense. Cellular responses to oxidative, thermal, and nutrient stress were characterized using stress indicators, such as pigment content, efficiency of photosystem II or production of reactive oxygen species (ROS), as well as hallmarks of apoptosis including activity of caspase-like enzymes and expression of a metacaspase gene homolog. The formation of temporary cysts, a survival strategy of short-term quiescence, was also monitored. Cellular responses appeared to depend on multifactorial influences where type and intensity of stimulus as well as position in cell cycle may act in combination. Sequences of events observed implicate ROS production as a key determinant of stress-related pathways, playing potential roles in intracellular signaling, formation of temporary cysts, or cellular damage. Variations observed in caspase-like activities and metacaspase gene expression did not appear to be associated with programmed cell death pathways; our results suggest a wider range of functions for these proteases in phytoplankton cells, including roles in survival pathways and cell cycle progression.

When the host is absent, the species survives with a distinctive pair of twin resting cysts described as Pyrocystis margalefii. Based on live samples, the formation of the twin resting cysts is illustrated here for the first time. The gymnodinioid infective cells did not form overwintering cysts under unfavourable conditions. These are formed inside the secondary lunate sporangium.

By contrast, spring blooms occurred only twice (in 2000 and 2007). During these periods, sea surface temperatures (SST) and the wind patterns appear to impact the bloom occurrences much more than the apparent limiting resources such as inorganic nutrients. The analysis of SST and wind from April to June and September to November (from 2000 to 2007) indicates first that there has to be an initial wind stress in order to resuspend the cysts buried in the sediment. Blooms then occur after a period of weak winds (<4 m s(-1)) and of stable SST close to 20 degrees C (+/- 2 degrees C). Those conditions appear to be most favorable for germination of Alexandrium cysts and its ensuing vegetative growth. This period of stability (a few days to a few weeks) allows the development of the inoculum from the cyst's germination, its cohesion because of reduced hydrodynamics, and development of vegetative cells that are sensitive to agitation. Strong winds during 1-2 day periods can interrupt the bloom dynamics by dispersing (advection due to southeasterly winds) and/or eliminating (turbulence due to northwesterly winds) the vegetative cells. In the spring, under the same conditions of optimal SST, strong wind episodes dominate and those, as well as biological factors very likely lead to a lower occurrence of blooms relative to the fall situation.

We propose that biofouling on ships' hulls is a potentially important mechanism for microalgae dispersal worldwide. Biofouling samples, for phytoplankton composition analysis, were collected in Spanish Mediterranean ports from the hulls of ships that had completed oceanic journeys from other Mediterranean ports, and long journeys from the Atlantic and Indian Oceans. Samples representing the local population of phytoplankton either in the water column or attached to the biofouling of locally-based ship-hulls were used as controls. A broad variety of microalgae species (including toxic dinoflagellates), which were not present in the local phytoplankton populations were found on the biofouling film of the ships that had been on distant journeys. In spite of the presence of the antifouling paints containing toxic compounds, microalgae were able to rapidly adapt to these non-favourable conditions. Consequently, our study shows that ships' biofouling seems to be a powerful vector for microalgae dispersal at a global scale due to the capacity of microalgae to attach to the biofouling film and to cope by adaptation mechanisms with antifouling compounds.

In the acidification experiment, the dissolution of calcareous spines of S. trochoidea cysts was observed at less than pH 7.39, indicating that the morphological change of S. trochoidea cysts is caused by the low pH levels in acidic sediments of hypoxic zone. After being exposed to intense acidic environments, cysts of S. trochoidea without calcareous spines were able to germinate; however, they seem to be easily linked to degradation in the sediments. These results suggest that the survival of S. trochoidea cysts is being threatened by environmental conditions in the hypoxic zone of eutrophied area. (C) 2013 Elsevier B.V. All rights reserved.

NOV; ALEXANDRIUM DINOPHYCEAE; ELECTRON-MICROSCOPY; MOLECULAR EVIDENCE; MEDITERRANEAN SEA; GEN. NOV.; CYSTS	Four Gymnodinium species have previously been reported to produce microreticulate cysts. Worldwide, Gymnodinium catenatum strains are conservative in terms of larger subunit (LSU) rDNA and internal transcribed spacer region (ITS) sequences, but only limited information on the molecular sequences of other species is available. In the present study, we explored the diversity of Gymnodinium by incubating microreticulate cysts collected from the Yellow Sea off China. A total of 18 strains of Gymnodinium, from three species, were established. Two of these were identified as Gymnodinium catenatum and Gymnodinium microreticulatum, and the third was described as a new species, Gymnodinium inusitatum. Motile cells of G. inusitatum are similar to those of Gymnodinium trapeziforme, but they only share 82.52% similarity in LSU sequences. Cysts of G. inusitatum are polygonal in shape, with its microreticulate wall composed of approximately 14 concave sections. G. microreticulatum strains differ from each other at 69 positions (88.00% similarity) in terms of ITS sequences, whereas all G. catenatum strains share identical ITS sequences and belonged to the global populations. Phylogenetic analyses, based on LSU sequences, revealed that Gymnodinium species that produce microreticulate cysts are monophyletic. Nevertheless, the genus as a whole appears to be polyphyletic. Paralytic shellfish toxins (PSTs) were found in all G. catenatum strains tested (dominated by 11-hydroxysulfate benzoate analogs and N-sulfocarmaboyl analogs) but not in any of the G. microreticulatum and G. inusitatum strains. Our results support the premise that cyst morphology is taxonomically informative and is a potential feature for subdividing the genus Gymnodinium. (C) 2013 Elsevier B.V. All rights reserved.

Feeding, respiration, and excretion of the Black Sea <i>Noctiluca scintillans</i> MacCartney in summer	OCEANOLOGY			English	Article							ALEXANDRIUM-TAYLORI DINOPHYCEAE; DINOFLAGELLATE; POPULATION; DYNAMICS; PLANKTON	Studies were conducted at the end of June 2011 in the coastal region of the northeastern part of the Black Sea. The bulk of the Noctiluca scintillans population was observed in the thermocline and reached a density of 40000 ind./m(3). Analysis of digestive vacuoles content showed that Noctiluca could consume cells of Neoceratium tripos and N. furca, which had been considered inedible for Black Sea zooplankton, as well as temporary cysts of dinoflagellates, presumably of the toxic genus Alexandrium. The Noctiluca population consumed in total 10-30% of the abundance of temporary cysts, 2-29% of primary production, and 2-9% of potential Calanus euxinus egg production. For the first time, the excretion rates of ammonium nitrogen and mineral phosphorus were measured for N. scintillans. Our calculations showed that in summer, excretion by Noctiluca contributed from 4 to 18% and from 15 to 53% of phytoplankton total nitrogen and phosphorus requirements, respectively. The specific growth rate of Noctiluca (0.17-0.35) in summer, estimated from data on the daily food intake and respiration rate, was close to the values obtained in spring.	[Drits, A.

Hydrogen peroxide and nitric oxide trigger redox-related cyst formation in cultures of the dinoflagellate <i>Lingulodinium polyedrum</i>	HARMFUL ALGAE			English	Article						Carotenoid; Gonyaulax; Harmful algal blooms; Oxidative stress; Peridinin; Photosynthesis	NITRATE REDUCTASE-ACTIVITY; SUPEROXIDE-DISMUTASE; GONYAULAX-POLYEDRA; ALEXANDRIUM-MINUTUM; LIPID-PEROXIDATION; PRODUCTION PATHWAY; CHLOROPHYLL-A; ENCYSTMENT; PERIDININ; OXYGEN	The dinoflagellate Lingulodinium polyedrum is a toxin producer that shows the ability of turning to resting cysts as a survival strategy when exposed to environmental unfavorable conditions, such as nitrogen and phosphorus depletion, abrupt changes in temperature or light, and chemical or mechanical stress. Algal adaptation to all these conditions involves hydrogen peroxide (H2O2) and nitric oxide (NO center dot) as key redox signals for housekeeping cellular processes. Thus, we aim here to shed light on the role of H2O2 and NO center dot (from aqueous decomposition of sodium nitroprusside, SNP)- as prooxidant agents and putative redox signals for encystment of the dinoflagellate L. polyedrum. Harsh oxidative stress imposed by 500 mu M H2O2 treatment forced L. polyedrum cells to rapidly encyst, in less than 30 min, whereas slower cyst formation was observed upon lower H2O2 doses. L. polyedrum encystment was marked by a significant increase in the antioxidant carotenoid peridinin, although other photosynthetic pigments (chlorophyll a and beta-carotene) and light-harvesting complexes (peridinin complex protein, PCP) were all diminished in cyst forms. Although SOD activity (a frontline antioxidant enzyme) was severely inhibited by increasing doses of H2O2, a theoretical compensatory effect was provided by the dose-dependent increase of ascorbate peroxidase activity (APX), which resulted in significant lower levels of lipid peroxidation during cyst formation. Although SNP data cannot be fully compared to those found with H2O2 treatments, changes in APX activity and in biomarkers of lipid and protein oxidation matched the dose-responses found in H2O2 experiments, revealing similar biochemical and morphological responses against increasing oxidative conditions during cyst formation. Our data significantly contribute to a better understanding of the relationship between encystment, photosynthesis, and antioxidant responses triggered by H2O2 and NO center dot in L. polyedrum, a harmful diarrhetic shellfish poisoning toxin (DSPs) producer.

NOV; GEN. NOV.; DINOFLAGELLATE; ULTRASTRUCTURE; BACILLARIOPHYCEAE	The presence of Biecheleria cincta (= Woloszynskia cincta) in the Chinese coasts is reported for the first time. In scanning electron microscope, three to five series of vesicles and an elongated apical vesicle (EAV) were visible in the epicone, and both the hypocone and the cingulum had three series of vesicles each. Thin sections revealed that B. cincta possesses stalked pyrenoids and an unusual eyespot consisting of a stack of cisternae with brick-like materials (type E), thus supporting its transfer from Woloszynskia to Biecheleria. Spiny cysts formed spontaneously in culture, with an encystment rate of around 20%. Both large subunit ribosomal DNA (LSU rDNA) and internal transcribed spacer region (ITS) sequences in 12 strains from the Chinese coasts were determined. Phylogenetic analyses based on LSU rDNA and ITS sequences using Bayesian inference and maximum likelihood revealed two distinct ribotypes (referred to as ribotype A and B) in B. cincta. ITS region pairwise distances within B. cincta ranged from 0.024 to 0.072, suggesting the existence of a complex of cryptic species.

Our results show a two-phase productivity pattern within HS1 that progressed from an interval of low marine productivity between similar to 19 and 16 kyr BP to a phase with an abrupt and large productivity increase from similar to 16 to 15 kyr BP. The second phase is characterized by distinct heavy planktonic delta C-13 values and high concentrations of heterotrophic dinocysts in addition to a significant cooling signal based on the reconstructions of past sea surface temperatures (SSTs). We conclude that productivity variations within HS1 can be attributed to a substantial shift of West African atmospheric processes. Taken together our results indicate a significant intensification of the North East (NE) trade winds over West Africa leading to more intense upwelling during the last millennium of HS1 between similar to 16 and 15 kyr BP, thus leaving a strong imprint on the dinocyst assemblages and sea surface conditions. Therefore, the two-phase productivity pattern indicates a complex hydrographic setting suggesting that HS1 cannot be regarded as uniform as previously thought (C) 2013 Elsevier B.V.

Sediment samples (top 0-3 cm depth) were collected from the continental shelf of the eastern Bering Sea (17 stations) and the Chukchi Sea (13 stations) together with a long core sample (top 0-21 cm depth) from one station in the Chukchi Sea during 2009-2012. The cysts were enumerated using the primuline staining method. Species identification of the cysts was carried out with multiplex PCR assay and the plate morphology of vegetative cells germinated from cysts in the both areas. Alexandrium cysts were widely detected in the both areas, ranging from not detected (<1 cysts cm(-3)) to 835 cysts cm(-3) wet sediment in the eastern Bering Sea and from not detected (<1 cysts cm(-3)) to 10,600 cysts cm(-3) in the Chukchi Sea, and all isolated cysts were genetically and morphologically identified as the North American clade A. tamarense. Their cysts were mainly distributed in the shallow continental shelf where the water depth was less than 100 m in both areas. The cysts were detected from the deep layer (18-21 cm depth of sediment core) of the long core sample. The present study confirmed the abundant existence of A. tamarense with wide range of distribution in these areas. This fact suggests that A. tamarense vegetative cells have appeared in the water column in the both areas. Furthermore, these abundant cyst depositions indicate that this species originally distributed in the Arctic and subarctic regions and well adapted to the environments in the marginal ice zone.

In this study, we explored the diversity of Alexandrium along the coast of China by incubating resting cysts collected from 7 sites. A total of 231 strains of Alexandrium belonging to 7 morphospecies were found. Among them, Alexandrium andersonii, Alexandrium fraterculum, Alexandrium leei, Alexandrium pseudogonyaulax, and Alexandrium tamutum were recorded from the China Sea for the first time. Partial large subunit (LSU) and/or internal transcribed spacer region (ITS1, ITS2, and 5.8S rDNA) sequences revealed two ribotypes of Alexandrium andersonii, Alexandrium leei, and Alexandrium tamarense: Atama complex Group I and IV. Atama complex Group I was exclusively distributed in the Yellow Sea and the Bohai Sea, whereas Group IV was restricted to the East China Sea and South China Sea. Atama complex Group I produced mainly N-sulfocarbamoyl toxins (C1/C2, 61-79% of total toxins) and gonyautoxins (GTX1/4, 17-37%). Alexandrium ostenfeldii strain ASBH01 produced NEO and STX exclusively (65% and 35%, respectively). Our results support the premise that Atama complex Group I is endemic to the Asian Pacific and includes cold water species, whereas Atama complex Group IV tends to inhabit warmer waters.

Here we investigate the impact of elevated pCO(2) and lowered pH on growth and calcification in the common calcareous dinoflagellate Thoracosphaera heimii. We observe a substantial reduction in growth rate, calcification and cyst stability of T. heimii under elevated pCO(2). Furthermore, transcriptomic analyses reveal CO2 sensitive regulation of many genes, particularly those being associated to inorganic carbon acquisition and calcification. Stable carbon isotope fractionation for organic carbon production increased with increasing pCO(2) whereas it decreased for calcification, which suggests interdependence between both processes. We also found a strong effect of pCO(2) on the stable oxygen isotopic composition of calcite, in line with earlier observations concerning another T. heimii strain. The observed changes in stable oxygen and carbon isotope composition of T. heimii cysts may provide an ideal tool for reconstructing past seawater carbonate chemistry, and ultimately past pCO(2). Although the function of calcification in T. heimii remains unresolved, this trait likely plays an important role in the ecological and evolutionary success of this species. Acting on calcification as well as growth, ocean acidification may therefore impose a great threat for T. heimii.

Semisynthesis of Radio labeled Amino Acid and Lipid Brevetoxin Metabolites and Their Blood Elimination Kinetics in C57BL/6 Mice	CHEMICAL RESEARCH IN TOXICOLOGY			English	Article							TISSUE DISTRIBUTION; GREENSHELL MUSSELS; PERNA-CANALICULUS; PBTX-3; OYSTER; EXCRETION; BINDING; PLASMA; ESTERS	Brevetoxin B (BTX-B), produced by dinoflagellates of the species Karenia, is a highly reactive molecule, due in part to an alpha,beta-unsaturated aldehyde group at the terminal side chain, leading to the production of metabolites in shellfish by reduction, oxidation, and conjugation. We have investigated in mice the blood elimination of three common bioactive brevetoxin metabolites found in shellfish, which have been semisynthesized from BTX-B in radioactive forms. BTX-B was reduced at C42 to yield [H-3] dihydro-BTX-B. [H-3] S-desoxy-BTX-B2 (cysteine brevetoxin B) was semisynthesized from BTX-B by the conjugation of cysteine at the C50 olefinic group then [H-3] radiolabeled by C42 aldehyde reduction. [HC] N-Palmitoyl-S-desoxy-BTX-B2 was prepared using S-desoxy-BTX-B2 as the starting material with addition of the [C-14] radiolabeled fatty acid via cysteine amide linkage. The elimination of intravenously administered [H-3] S-desoxy-BTX-B2, [C-14] N-palmitoyl-S-desoxy-BTX-B2, or [H-3] dihydroBTX-B was measured in blood collected from C57BL/6 mice over a 48 h period. Each brevetwdn metabolite tested exhibited biexponential elimination kinetics and fit a two-compartment model of elimination that was applied to generate toxicokinetic parameters. The rate of transfer between the central compartment (i.e., blood) and the peripheral compartment (e.g., tissue) for each brevetoxin differed substantially, with dihydro-BTX-B exchanging rapidly with the peripheral compartment, S-desoxy-BTX-B2 eliminating rapidly from the central compartment, and N-palmitoyl-S-desoxy-BTX-B2 eliminating slowly from the central compartment. Toxicokinetic parameters were analyzed in the context of the unique structure of each brevetoxin metabolite resulting from a reduction, amino acid conjugation, or fatty acid addition to BTX-B.

Sieved sediments were incubated for 20 and 40days, and germinated vegetative cells were observed. Altogether, 97 taxa were recorded, of which 50 were diatoms and 35 dinoflagellates. Vegetative cells of cyanobacteria, chlorophytes, dictyophytes, euglenophytes, haptophytes, and raphidophytes were also observed. Centric diatoms such as Chaetoceros, Melosira, Skeletonema, and Thalassiosira dominated. Scrippsiella, Gymnodinium, and Alexandrium were common dinoflagellate taxa. Diatom spores germinated in samples from all seasons but were abundant in the autumn and winter samples. Low numbers of dinoflagellate cells germinated in the winter samples. The nanophytoplankton taxa, Gymnodinium corii and Chrysochromulina sp., which have not been recorded in the previous phytoplankton surveys, were abundant, suggesting either their new appearance in the water column or perhaps that they were overlooked in routine phytoplankton monitoring due to their small sizes. Vegetative cells of harmful or potentially harmful taxa were germinated, and some of them such as Amphidinium, Gambierdiscus, Ostreopsis, and Coolia have not previously been reported in the study area. Based on the results of the incubation of sediments from the two bays near the international ports, it is suggested that international shipping increases the risk of the introduction of new phytoplankton species and thus promotes the incidence of harmful algal blooms.

Living cysts provided for incubation experiments were collected from several places in Japan, including Omura Bay, West Japan and Lake Saroma in Hokkaido, North Japan. One hundred and four cysts were incubated and 18 motile cells were germinated from these cysts. To clarify their morphological characteristics both cysts and germinated thecate cells were observed, especially the archeopyle type, the number and shape of anterior intercalary plates, and the shape and development of apical and antapical horns. In order to provide molecular phylogenetic analysis, germinated cells from incubated cysts were examined for their LSU rDNA sequences. Results reveal that three morphologically different cysts produced three morphologically different thecate cells, which were previously known as Protoperidinium oblongum var. latidorsale, Protoperidinium oblongum var. inaequale, and Protoperidinium oblongum var. symmetricum. The molecular phylogenetic analysis demonstrated that the Oceania group in the genus Protoperidinium includes these three varieties as well as Protoperidinium divergens, Protoperidinium claudicans, and Protoperidinium steigingerae. This group is separated from Protoperidinium sensu strict, and the three plankton forms are phylogenetically separate and independent species. Based on these facts, two new species, Protoperidinium quadrioblongum Sarai, Kawami et Matsuoka, the new name for Protoperidinium oblongum var. symmetricum and Protoperidinium paraoblongum Sarai, Kawami et Matsuoka for Protoperidinium oblongum var. inaequale are described.

Results from the percentage analysis and statistical methods such as multivariate ordination analysis and end-member modelling, indicate the existence of three distinct environmental and oceanographic regions in the study area. Region I is located in western and eastern Indonesia and controlled by high SSTs and a low nutrient content of the surface waters. The Indonesian Throughflow (ITF) region (Region 2) is dominated by heterotrophic dinocyst species reflecting the region's high productivity. Region 3 is encompassing the area offshore north-west and west Australia which is characterised by the water masses of the Leeuwin Current, a saline and nutrient depleted southward current featuring energetic eddies.

The spatial patterns of cyst density in relation to sediment characteristics and hydrodynamics are still largely misunderstood. This study investigated the spatial distribution of resting cysts belonging to the Alexandrium tamarense species complex (Dinophyceae) in sediments of a Mediterranean coastal lagoon (Thau Lagoon, France). This lagoon, hosting shellfish farming, is regularly impacted by toxic Alexandrium catenella blooms. The average cyst density across the whole lagoon was rather low, <20 cysts g(-1) of dry sediment (DS). However, densities varied widely among sampled stations, with the highest density (similar to 440 cysts g(-1) DS) recorded in a shallow cove named Crique-de-l'Angle, which is the only area where dense blooms of A. catenella and A. tamarense have been recorded in the years preceding this survey. An analysis using spatial autoregressive models demonstrated that cyst densities were highly spatially autocorrelated (indicating that close stations tended to have more similar cyst densities) with accumulation sites. With respect to sediment characteristics (5 granulometric fractions <2 mm and biochemical components), the highest densities were found in silty sediments containing high proportions of water and organic matter. Nevertheless, the linkage between cyst density and sediment structure was not always verified; this reflected the influence of hydrodynamics on the sedimentation of cysts and sediment particles, and on the dispersal of cysts away from the bloom area by wind-induced currents, suggesting that hydrodynamics was responsible for the spatially autocorrelated distribution of cyst densities.

Here, we show that the generalist dinoflagellate parasitoid Parvilucifera sinerae (Perkinsozoa, Alveolata) is activated from dormancy, not only by Alexandrium minutum cells but also by culture filtrates. We unequivocally identified the algal metabolite dimethylsulphide (DMS) as the density-dependent cue of the presence of potential host. This allows the parasitoid to alternate between a sporangium-hosted dormant stage and a chemically-activated, free-living virulent stage. DMS-rich exudates of resistant dinoflagellates also induced parasitoid activation, which we interpret as an example of coevolutionary arms race between parasitoid and host. These results further expand the involvement of dimethylated sulphur compounds in marine chemical ecology, where they have been described as foraging cues and chemoattractants for mammals, turtles, birds, fish, invertebrates and plankton microbes.

However, a growing body of evidence suggests that marine protists, including several phytoplankton species, are in fact highly diverse and may quickly respond to changes in the environment. Predicting how future climate will impact phytoplankton populations is important, but this task has been challenged by a lack of time-series of ecophysiological parameters at time-scales relevant for climate studies (i.e. at least decadal). Here, we report on ecophysiological variability in a marine dinoflagellate over a 100-year period of well-documented environmental change, by using the sedimentary archive of living cysts from a Scandinavian fjord (Koljo Fjord, Sweden). During the past century, Koljo Fjord has experienced important changes in salinity linked to the North Atlantic Oscillation (NAO). We revived resting cysts of Pentapharsodinium dalei preserved in the fjord sediments and determined growth rates for 18 strains obtained from 3 sediment core layers at salinity 15 and 30, which represent extreme sea-surface conditions during periods of predominantly negative and positive NAO phases, respectively. Upper pH tolerance limits for growth were also tested. In general, P. dalei grew at a higher rate in salinity 30 than 15 for all layers, but there were significant differences among strains. When accounting for inter-strain variability, cyst age had no effect on growth performance or upper pH tolerance limits for this species, indicating a stable growth response over the 100-year period in spite of environmental fluctuations. Our findings give some support for the use of morphospecies in environmental studies, particularly at decadal to century scales. Furthermore, the high intra-specific variability found down to sediment layers dated as ca. 50 years-old indicates that cyst-beds of P. dalei are repositories of ecophysiological diversity.

In August 2008, a major bloom of A. tamarense developed in the SLE and caused major mortality of fish, seabirds and marine mammals notably in the vicinity of a marine park. Eleven months later, surface (0-5 cm) and deeper (5-10 cm) sediments were sampled to determine resting cysts concentrations, locate prospective cyst seedbeds and examine if these had changed following this major bloom. This information is thought to be important to understand inter-annual patterns in algal toxicity, cyst abundance being a good predictor of subsequent bloom magnitude in some regions. Surface cyst distribution was heterogeneous and it confirmed the location of the cyst seedbed previously reported on the north shore near the Manicouagan/aux-Outardes Rivers (>500 cysts cm(-3)). A zone of cyst accumulation was also observed on the south shore of the SLE (maximum of 1200 cysts cm(-3)), with higher concentrations relative to previous cyst mapping in the 1980s. A mismatch was observed between the zones with high surface cyst concentrations and those where the highest PSP toxins were detected (used as a proxy for vegetative cells in the water column). Cyst concentrations were negatively correlated with PSP levels from the same sites, suggesting that cysts were formed and deposited away from the major sites of toxicity. Deposition likely took place near the end of the bloom, once it had reached the eastern boundary of the SLE. PSP toxicity was worse near the peak of the bloom, which occurred westward of this region. This highlights the dynamic behaviour of local blooms, influenced by the estuarine and mesoscale circulation. Interestingly, the major bloom of August 2008 was not followed by particularly large cyst deposition or by any major bloom in 2009 in this region. Cyst viability was also examined, using Sytox Green, and found to be highest (nearly 100%) in the sites where cyst concentrations were maximum. Our results call for further investigation of the cyst mapping hypothesis in the St. Lawrence, where the local circulation seems to have an overriding influence on cyst deposition patterns.

Individual respiration rates were standardised to a mean copepod body mass and a temperature regime typical of the northern Benguela Current. These adjusted respiration rates revealed two different activity levels (active and resting) in copepodids C5 of Calanoides carinatus and females of Rhincalanus nasutus, which reduced their metabolism during dormancy by 82% and 62%, respectively. An allometric function (I-max) and an energy budget approach were performed to calculate ingestion rates. I-max generally overestimated the ingestion rates derived from the energy budget approach by >75%. We suggest that the energy budget approach is the more reliable approximation with a total calanoid copepod (mainly females) consumption of 78 mg C M-2 d(-1) in neritic regions and 21 mg C m(-2) d(-1) in oceanic regions. The two primarily herbivorous copepods C. carinatus (neritic) and Nannocalanus minor (oceanic) contributed 83% and 5%, respectively, to total consumption by calanoid copepods. Locally, C. carinatus can remove up to 90% of the diatom biomass daily. In contrast, the maximum daily removal of dinoflagellate biomass by N. minor was 9%. These estimates imply that C. carinatus is an important primary consumers in the neritic province of the northern Benguela system, while N. minor has little grazing impact on phytoplankton populations further offshore. Data on energy requirements and total consumption rates of dominant calanoid copepods of this study are essential for the development of realistic carbon budgets and food-web models for the northern Benguela upwelling system.

J	Casas-Monroy, O; Roy, S; Rochon, A				Casas-Monroy, Oscar; Roy, Suzanne; Rochon, Andre			Dinoflagellate cysts in ballast sediments: differences between Canada's east coast, west coast and the Great Lakes	AQUATIC CONSERVATION-MARINE AND FRESHWATER ECOSYSTEMS			English	Article						ballast sediment introductions; dinoflagellate cysts; non-indigenous species; Canadian coastal regions; ballast water exchange	EEMIAN HYDROGRAPHIC CONDITIONS; BIOLOGICAL INVASIONS; TANK SEDIMENTS; RESTING CYSTS; BALTIC SEA; NORTH-SEA; WATER; SHIPS; TRANSPORT; COCHLODINIUM	The abundances and diversity of dinoflagellate cysts (including non-indigenous or harmful species) in ballast sediments were examined for the east and west coasts and the Great Lakes, to assess the potential invasion risk for these organisms and to determine similarity across regions. In total, 147 ships were sampled, distributed among three categories: (1) transoceanic, with mandatory ballast water exchange (BWE); (2) coastal with BWE; and (3) coastal without BWE. Factors that could account for variability in results were examined including ship routes, BWE, ballast water age and sediment volume in ballast tanks. The pattern of potential invasion risk differs according to the region examined. The east coast had greater concentrations of viable cysts per tank, particularly for coastal ships (with a maximum close to 2x106 cysts per tank in coastal exchanged ships compared with 1x105 for the west coast). When considering viable cysts g-1 dry sediment, maximum concentrations were found in unexchanged coastal ships from the east coast (28 cysts g-1 compared with 5 for the west coast), but these ships contained less sediment, decreasing the overall abundance of cysts per tank. These results are in the lower range of values reported for Scotland or Australia, which reached a maximum of 2.3x104 cysts cm3 of sediment. Ballast water exchange had a different influence according to the region: on the east coast, the invasion risk was reduced by BWE while it had no significant effect in the other two regions. Ballast water age and sediment volume were also different among regions, but they were not clearly related with cyst concentrations in ballast tanks. Future management of ballast sediment should take into consideration these regional differences in order to reduce the introduction of dinoflagellate NIS that threaten the conservation of coastal habitats through reduction of native diversity.Copyright (c) 2012 John Wiley & Sons, Ltd.

J	Tillmann, U; Hoppenrath, M				Tillmann, Urban; Hoppenrath, Mona			Life Cycle of the Pseudocolonial Dinoflagellate Polykrikos kofoidii (Gymnodiniales, Dinoflagellata)	JOURNAL OF PHYCOLOGY			English	Article						cysts hatching; dinoflagellate; gamete; life cycle; nuclear cyclosis; Polykrikos kofoidii	SEXUAL REPRODUCTION; CATENATUM DINOPHYCEAE; CULTURE; MEIOSIS; MORPHOLOGY; NOCTILUCA; NOV; ENCYSTMENT; PHYLOGENY; EHRENBERG	The athecate, pseudocolonial polykrikoid dinoflag-ellates show a greater morphological complexity than many other dinoflagellate cells and contain not only elaborate extrusomes but sulci, cinguli, flagellar pairs, and nuclei in multiple copies. Among polykrikoids, Polykrikos kofoidii is a common species that plays an important role as a grazer of toxic planktonic algae but whose life cycle is poorly known. In this study, the main life cycle stages of P. kofoidii were examined and documented for the first time. The formation of gametes, 2-zooid-1-nucleus stages very different from vegetative cells, was observed and the process of gamete fusion, isogamy, was recorded. Karyogamy followed shortly after completed plasmogamy. A complex reorganization of furrows (cinguli and sulci) and flagella followed zygote formation, resulting in a 4-zooid zygote with one nucleus. The fate of zygotes under different nutritional conditions was also investigated; well-fed zygotes were able to reenter the vegetative cycle via meiotic divisions as indicated by nuclear cyclosis. However, nuclear cyclosis was preceded by a presumably mitotic division of the primary zygote nucleus which by definition would imply that P. kofoidii has a diplohaplontic life cycle. Nuclear cyclosis in germlings hatched from spiny resting cysts indicate that these cysts are of zygote origin (hypnozygotes). Hypnozygote formation, cyst hatching, the morphology of the germling (a 1-zooid cell), and its development into a normal pseudocolony are documented here for the first time. There is evidence that P. kofoidii has a system of complex heterothallism.

Sediment cores were taken from 10 stations in Alfacs Bay and from 6 stations in Fangar Bay. Sediment samples from the surface (the top 1 cm) and the subsurface profile (from 2 to 5 cm depth) in selected stations, were analyzed. Sixty-two morphotypes were recovered, some of which are new reports for the northwestern Mediterranean area. Few morphotypes dominated in terms of abundance and relative percentage (e.g. the Scrippsiella trochoidea complex was the dominant and most widely distributed morphotype in each bay, reaching maxima of 163 cysts cm(-3) wet sediment (ws) and 102 cysts cm(-3) ws in Alfacs and Fangar bays, respectively). The assemblage in Alfacs Bay was also characterized by the presence of Biecheleria cincta (maximum 116 cysts cm(-3) ws), whereas the occurrence of Pentapharsodinium tyrrhenicum (maximum 37 cysts cm(-3) ws) was greater in Fangar Bay. Twelve morphotypes belonging to potentially toxic or noxious species were detected, with the genus Alexandrium dominating. Among the harmful species, Gymnodinium litoralis and Vulcanodinium rugosum are reported for the first time from the study areas. Furthermore, cysts of the high biomass bloom-forming species Kryptoperidinium foliaceum are reported for the first time in the Mediterranean Sea. All the harmful species, with the exception of Alexandrium minutum, showed greatest abundances in subsurface samples. Profile analysis led to the description of a new cyst morphotype belonging to the Alexandrium genus (presumably A. insuetum). Our results provide information on the presence of harmful species in the studied bays, confirming the usefulness of cyst analysis in assessment of the potential risk of harmful blooms in aquaculture areas.

Dark survival in a warming world	PROCEEDINGS OF THE ROYAL SOCIETY B-BIOLOGICAL SCIENCES			English	Review						dark survival; Antarctic; winter; microalgae; phytoplankton	SEA-ICE ALGAE; MCMURDO SOUND; WEDDELL SEA; MARINE-PHYTOPLANKTON; ANTARCTIC LAKE; LIGHT; DIATOMS; WINTER; PHOTOSYNTHESIS; TEMPERATURE	Most algae regularly experience periods of darkness ranging from a few hours to a few days. During this time, they are unable to photosynthesize, and so must consume stored energy products. However, some organisms such as polar algae and some microalgal cysts and spores are exposed to darkness for months to years, and these must use alternative strategies to survive. Some taxa, such as dinoflagellates, form cysts and become dormant. Others use physiological methods or adopt mixotrophy. The longest documented survival of more than a century was for dinoflagellates buried in sediments in a Norwegian fjord. Seasonal changes in daylight hours are naturally unaffected by climate change. This means that polar microalgae will in the future need to survive the same period of seasonal darkness but at higher temperatures, and this will require a greater drawdown of stored energy. Recent experimental work has shown that both Arctic and Antarctic phytoplankton are able to survive increases of up to 6 degrees C in the dark.

Classification of Scrippsiella traditionally relied on cyst morphology because the plate pattern was rather conserved. A new species, S. enormis sp. nov. was obtained by incubating a noncalcified cyst from sediments collected in the East China Sea. The vegetative cells consisted of a conical-convex epitheca and a round hypotheca with the plate formula of po, x, 4', 3a, 7', 6c (5c+t), 5s, 5'''', 2''''. It differed from other Scrippsiella species by possessing an asymmetrical 1' and generating noncalcareous, spherical cysts with paratabulation. Phylogenetic analyses based on internal transcribed spacer (ITS) and 5.8S rDNA sequences revealed that S. enormis was nested within the Calciodinellum clade. In addition, two strains of S. cf. spinifera (strains SSFC02, SSFC03) were obtained by incubating calcareous cysts from sediments collected in the South China Sea. They shared identical ITS sequence and formed a sister clade of the S. trochoidea species complex, suggesting little phylogenetic significance of antapical spines in Scrippsiella.

Information of the biogeography of the Atama complex is limited in the Arctic Ocean. In the present study, we established 55 strains of the Atama complex by incubating ellipsoidal cysts collected from the Chukchi Sea. The vegetative cells are characterized by a prominent ventral pore, thereby fitting the description of A. tamarense morphotype. Large subunit (LSU) and/or internal transcribed spacer (ITS) region sequences of these strains were examined. Both sequences showed intragenomic polymorphism. The 708 bp of the LSU sequences from the strains differed from each other at 0-44 sites (0.0-6.2 %), and the ITS region sequences differed from one another at 0-28 sites (0.0-5.4 %). Phylogenetic analysis revealed that the Chukchi Sea strains were nested within Atama complex (Group I). Assessment of paralytic shellfish poisoning toxin production by four Chukchi Sea strains using high-performance liquid chromatography showed that total toxin per cell ranged from 9 to 41 fmol cell(-1). The toxin profile of the four strains from the Chukchi Sea is conserved, with the major toxins being N-sulfocarbamoyl toxin (C2), saxitoxin, and gonyautoxin-4. Our results support that dispersal of the Atama complex (Group I) from the Bering Sea to the Chukchi Sea might have occurred.

Life cycle transitions between bloom forming cells and resting cysts are assumed to regulate the bloom dynamics of this species. We investigate the seasonal cycle and succession of Biecheleria balticas life cycle stages using a numerical model with four different stages, vegetative cells, gametes, resting cysts and germinating cells. The transitions among the stages are functions of environmental conditions and endogenous factors. Coupled to a water column model, the model is able to represent the seasonal cycle of Biecheleria baltica with two blooms in spring. The first bloom can be explained by germination of resting cysts in winter, the second by growth of vegetative cells. Sensitivity experiments indicate that temperature is an important factor regulating the composition of Biecheleria baltica life cycle stages; increased or decreased temperature leads to fewer growing cells and more resting cysts during spring. Our newly developed life cycle model can be used to study in more detail cyst formation, cyst distribution and consequences for biogeochemical cycling in the past and future.

J	Brown, L; Bresnan, E; Summerbell, K; O'Neill, FG				Brown, Lyndsay; Bresnan, Eileen; Summerbell, Keith; O'Neill, Finbarr Gerard			The influence of demersal trawl fishing gears on the resuspension of dinoflagellate cysts	MARINE POLLUTION BULLETIN			English	Article						Sediment; Resuspension; Dinoflagellate cyst; Towed fishing gear	ALEXANDRIUM-TAMARENSE DINOPHYCEAE; RECENT MARINE-SEDIMENTS; SWEDISH WEST-COAST; RESTING CYSTS; BALTIC SEA; ENVIRONMENTAL-FACTORS; SCRIPPSIELLA-HANGOEI; SCOTTISH WATERS; SHORT-TERM; GERMINATION	To investigate the influence of towed demersal fishing gears on dinoflagellate cyst resuspension, towing trials with four gear components were carried out at three sites of differing sediment type in the Moray Firth, Scotland. Samples of sediment plumes were collected using plankton nets mounted on a towed sledge. Diversity of resuspended dinoflagellate cysts was similar at all sites and included Protoperidinium and Gonyaulax spp., Proroceratium reticulatum and unidentified 'round brown' cysts. Cyst concentrations per gram of resuspended sediment varied by gear component and sediment particle size distribution. Gear components with lower hydrodynamic drag generated wakes with smaller shear stresses, mobilising fewer larger sand particles, giving larger concentrations of cysts. Muddy sediments contained higher cyst concentrations which declined with increasing grain size. This study has shown that fishing gear and sediment type can influence the redistribution of dinoflagellate cysts and highlights the importance this may have in relation to dinoflagellate blooms.

The cyst abundance varied from 11 to 1218 cysts g(-1) dry sediment. Changes in the cyst assemblages from phototrophic to heterotrophic forms were observed from inner to outer harbour stations, and related to changes in environmental characteristics. Enhanced cyst production of potentially harmful dinoflagellate Protoceratium reticulatum was recorded in the inner harbour stations with higher nutrient concentrations. Protoperidinium cysts were the most diversified group, and were dominant in the outer harbour stations having improved water conditions and circulation. This study points out the potential use of dinoflagellate cyst populations in providing information on environmental conditions. (C) 2012 Elsevier Ltd. All rights reserved.

The average cyst concentrations of that species ranged from 4033 +/- 2647 to 220872 +/- 148 086 cysts g(-1) of dry sediments and the highest concentrations were found near ship terminals in Bedford Basin. Although this species is endemic to this region, our work strongly suggests that some of the cysts of A. tamarense species complex found in the port of Halifax were introduced through discharged ballast water and sediments.

Vacuolar crystal-like particles as well as collection sites within the prospective calcareous shell may play a crucial role during this process at the ultrastructural level. Using transmission electron microscopy, we investigated the ultrastructure of coccoid cells at an early developmental stage in fourteen calcareous dinophyte strains (corresponding to at least ten species of Calciodinellum, Calcigonellum, Leonella, Pernambugia, Scrippsiella, and Thoracosphaera). The shell of the coccoid cells consisted either of one (Leonella, Thoracosphaera) or two matrices (Scrippsiella and its relatives) of unknown element composition, whereas calcite is deposited in the only or the outer layer, respectively. We observed crystal-like particles in cytoplasmic vacuoles in cells of nine of the strains investigated and assume that they are widespread among calcareous dinophytes. However, similar structures are also found outside the Thoracosphaeraceae, and we postulate an evolutionarily old physiological pathway (possibly involved in detoxification) that later was specialized for calcification. We aim to contribute to a deeper knowledge of the biomineralization process in calcareous dinophytes.

The quality of modern microscopes and other laboratory equipment, coupled with enhanced computer capabilities, has extended the frontiers of research beyond what was thought possible even half a century ago. New research topics have emerged in accordance with today's scientific and socio-economic priorities. Here we describe six of these research areas that have the most potential to advance our knowledge of dinoflagellate ecology and systematics.

Diversity of dinoflagellate life cycles: facets and implications of complex strategies	BIOLOGICAL AND GEOLOGICAL PERSPECTIVES OF DINOFLAGELLATES	Micropaleaeontological Society Special Publications		English	Article; Book Chapter							GYMNODINIUM-CATENATUM DINOPHYCEAE; ALEXANDRIUM-MINUTUM; CYST FORMATION; SCRIPPSIELLA-HANGOEI; REPRODUCTIVE SUCCESS; SEXUAL REPRODUCTION; MATING-TYPE; ENCYSTMENT; BLOOM; PHYTOPLANKTON	The life cycle research of the past years has revealed an unexpectedly high diversity of reproduction and survival strategies. Dinoflagellate life cycles often seem to be plastic, i.e. different pathways and mechanisms may be complementary in one and the same species. The diversity of life cycle stages, strategies and regulation mechanisms will have implications for the understanding of ecological processes and functions. Versatility in reproduction and survival strategies will affect genetic diversity patterns and standing genetic variation which are important factors in adaptation to changing conditions and stability against environmental disturbance. Complex regulation mechanisms and multiple cues for life cycle transformations can lead to differences in the magnitude of cyst formation and sedimentation and thereby determine the fate of primary production. Life cycles are an important life history trait of dinofiagellates which, in their versatility and complexity, contribute to the functional diversity that structures and determines the functioning of aquatic systems.

Dinoflagellate life cycles, strategy and diversity: key foci for future research	BIOLOGICAL AND GEOLOGICAL PERSPECTIVES OF DINOFLAGELLATES	Micropaleaeontological Society Special Publications		English	Article; Book Chapter							SEXUAL REPRODUCTION; CYST FORMATION; GEOCHEMICAL SIGNIFICANCE; STEROL COMPOSITION; MOLECULAR EVIDENCE; SURFACE SEDIMENTS; ORGANIC-MATTER; DINOPHYCEAE; SCRIPPSIELLA; PRESERVATION	Within dinoflagellate research the fields of geology and biology come together in studies of the resting stage, the cyst. Studies of this stage and life-cycle transitions can tie together the geological fossil record of dinoflagellates and the ecology of living dinoflagellates. This review focuses on possible new research areas within ploidy shifts in dinoflagellate life cycles, the role of the cyst in benthic-pelagic coupling, the cyst as the link between the past and present, the role of cysts in long-term survival and preservation of cysts and cyst-wall chemistry.

This genus consists of c. 300 species (Hoppenrath et al. 2009), all of which are completely heterotrophic. Although several different classification schemes in the genus Protoperidinium Berg (formerly the genus Peridinium Ehrenberg) have been proposed by different scientists (e.g. Jorgensen 1912; Lebour 1925; Abe 1981), the genus has been treated as a well-established taxonomic unit even after the revision of the genus Peridinium by Balech (1974). Since the plate formula and the shape of each plate developed in Protoperidinium species are stable, the combination of plate topology and shape have been regarded as key features for subdivision within the genus and identification of species.

DINO 9 Workshop Report: Linking dinoflagellate life-cycle stages using single-cell isolation and molecular typing	BIOLOGICAL AND GEOLOGICAL PERSPECTIVES OF DINOFLAGELLATES	Micropaleaeontological Society Special Publications		English	Article; Book Chapter							PCR; DINOPHYCEAE; PROTISTS; PROTOPERIDINIUM; IDENTIFICATION; AMPLIFICATION; CYSTS; DNA	This workshop aimed to expose the participants to simple techniques for manipulation of single cells and cysts, with current and emerging DNA technologies to identify the genetic and taxonomic affinities of cyst/cell morphotypes and link different life-cycle stages of dinoflagellates. The workshop was attended by over 45 participants (from 23 countries), ranging from research (Masters and PhD) students through to senior researchers. The workshop kicked off with two short presentations from the workshop leaders. Dr Bolch described and demonstrated the practice of manual mouth pipetting (including a short video) using both stereo- and compound microscopes. Simple techniques to improve success rate of manual manipulations were covered as were ways of minimizing saltwater/media carry over with transfer of single cells to PCR tubes. Dr Percy presented a range of alternative manipulation methods (including video presentations) that avoid mouth pipetting, a practice that is increasingly banned in laboratories where work with human or infectious agents may be carried out in the same areas as lower-risk activities. Following the presentations, all participants practised the demonstrated methods with live dinoflagellate cells using simple mouth pipettes and other devices supplied by the presenters, using a range of equipment made available by the University of Liverpool laboratory and academic staff. Most participants experienced successful manipulation and transfer of single cells during the hour of practice. All participants considered the workshop valuable and that the very simple manipulations could be usefully implemented in their own laboratories for specific research questions and projects. A number of participants also decided to keep their piece of silicon tubing to manufacture a similar device on return to their lab. Toward the end of the workshop, a short presentation from Dr Bolch focused on how some current and emerging technologies (laser-microdissection, flow cytometry, pico-litre droplet manipulation) can be combined with molecular methods (multiple displacement amplification) to achieve both highly selective and automated high-throughput manipulation for molecular and genomic scale analysis of single bacteria through to phytoplankton protistan cells. The workshop presenters thank Dr David Montagnes and lab staff at the University of Liverpool for enthusiastic assistance and efforts to round up suitable equipment to run the workshop. Thanks also go to Dr Joe Taylor (University of Westminster) for his on-the-ground organization and logistics to ensure that the workshop would be a success. The workshop technical notes are reproduced below for a wider audience.

Samples from 8 stations revealed the presence of 24 species from the genera Protoperidinium, Zygabikodinium, Gonyaulax, Lingulodinium and Gyrodinium. Cyst abundance was comparatively high at northern stations and was well correlated with the fine-grained (silt-clay dominated) sediments. In contrast, low cyst abundance was recorded in sandy sediments at southern stations. Fourteen cyst-forming dinoflagellate species previously unrecorded in planktonic samples were detected in the sediments. The cyst abundance recorded here is low (29-331 cysts g(-1). dry sediment) as compared to sub-tropical and temperate regions, but it is on a par with tropical regions, including the west coast of India. Comparison of the cyst assemblage along the Indian coast revealed a smaller number of potentially harmful and red-tide-forming dinoflagellate species on the south-east coast (6 species) than on the west coast (10 species). Calcareous cysts of the genus Scrippsiella reported from the west coast and Visakhapatnam harbour (south-east coast) were not observed in this study although their planktonic cells have been reported.

Inactivation effect on microalgae by combined PEF and engine waste heat pretreatment was studied. Effect factors such as pulsed voltage, electrode gap, pulse width and preheating temperature were explored, and its mechanism of inactivate the microalgae was analyzed. The results show that at the same experimental parameters, the inlet temperature of PEF treatment stage keeps at 24 degrees C, the inactivation percentage is difficult to achieve 90% unless the electric field strength rises to 22 kV/cm. Once the PEF treatment sample is preheated to 48 degrees C, the inactivation percentage will be up to 99% as the electric field strenth is just 10 kV/cm.

A total of 28 types of identified cysts belonged to the following 11 genera: Alexandrium, Diplopsalis, Ensiculifera, Gonyaulax, Gyrodinium, Pentapharsodinium, Polykrikos, Preperidinium, Protocera- tium, Protoperidinium, and Scrippsiella. The morphology of dinoflagellate cysts from recent sediments of Russian seas, such as the shape, the size, and also the structure of the phragma, including the processes and the archeopyle, was described comprehensively for the first time. Cysts of the species Gonyaulax spinifera, Pentapharsodinium dalei, Protoceratium reticulatum, Protoperidinium americanum, P. conicoides, P. subinerme, Scrippsiella crystallina, and S. trochoidea were the most widespread. Those of the potentially toxic species Alexandrium tamarense were also widely distributed and prevailed in the studied area. Their concentration varied from 0 to 25 860 cells/cm(3); the maximum concentration was recorded in Pavel Bay, Koryak Okrug, and Kamchatka.	[Orlova, T. Yu; Morozova, T.

This behavior was studied, and quantitative measures of these motility patterns in two-dimensions were generated using motion-analysis software applied to video records of individual-cell movements. Behavior, swimming patterns, and growth were studied in two strains of A. fundyense and compared in encystment medium and growth medium. Vegetative cells swam straight, rotating around the apical axis until they hit something and then swam straight in a different direction. Gamete swimming behavior was slower and characterized by frequent direction changes and circular motion. Gametes contacted other cells frequently (>5 cell contacts min(-1) cell(-1)). Zygotes swam slowly when newly formed and later became nearly immobile; these cells continued to contact other cells and also surfaces. The results are in accordance with field observations of long swimming distances for vegetative cells, accumulation in thin layers of gametes, and sinking of developing resting cysts attached to marine snow for zygotes.

In confined basins, usually characterised by low hydrodynamic conditions and high productivity, cysts produced in the water column sink to the sediments where they may remain viable for many years, constituting a reservoir of potential biodiversity. Dinoflagellate species are capable of forming dormant cysts. The analysis of these resting forms leads to a better consideration of rare species in the water column and to improve knowledge of planktonic biodiversity. In this context, a study was conducted, through two field campaigns in 2010, touching the four commercial ports situated in the Gulf of Gabes namely the ports of Sfax, Skhira Gabes and Zarzis. Thus, the search for Dinophyceae rest forms was resulted in the identification of 37 cysts taxa that can be added to the list of plankton species, and from which 17 were not found in their active form. Furthermore, the surface sediments of the Sfax, Skhira, Gabes and Zarzis harbour areas were characterized, respectively, by the presence of 16, 18, 18 and 13 cysts taxa, belonging to the orders, Gymnodiniales, Prorocentrales, Gonyaulacales and Peridiniales. The two latters represented the most dominant groups. Among the non-indigenous species in the Mediterranean sea we identified in this work, 6 encysted forms including those of the five potentially toxic species Gymnodinium catenatum, Karenia selliformis, Alexandrium minutum and Protoceratium reticulatum. The two encysted forms of Gymnodinium cf impudicum and Ensiculifera cf carinata were reported for the first time in Gulf of Gabes. The highest density cyst was mainly observed in the Zarzis port area (660 cysts g(-1) DW sediment). It was generated by the alien species Scrippsiella trochoida.

In the San Jose, Yavaros, and El Colorado lagoons, the vegetative stage peaked at 63, 108, and 151 (x10(3) cells l(-1)), respectively. At San Jose, production of cysts peaked at 9.7x10(3) g(-1) of dry sediment mass as the bloom declined. Large diatoms predominated, with P. bahamense the most common dinoflagellate during the blooms. Abundance of P. bahamense at San Jose was positively correlated with salinity (r=0.50, p=0.0003), seawater temperature (r=0.44, p=0.005), silicates (r=0.45, p=0.003), and ammonium (r=0.32, p=0.005), and negatively correlated with dissolved oxygen (r=-0.34, p<0.0001). No such correlations were found at El Colorado and Yavaros. The environmental window that favors development of blooms is restricted to the summer and is influenced by seawater temperature, salinity, and relative concentrations of ammonium and phosphates that, in turn, depend on rainfall and runoff, which is greater on the eastern side of the Gulf where seawater quality is degraded.

The theca of A. saanichi is differentiated from related species by overall size, the asymmetry of the intercalary plates and the right-sulcal plate (S.d.) not touching the cingulum. We provide a key to differentiate all closely related species. A. saanichi can be readily distinguished from A. minutum by a distinctively large cyst with a broad 2a type archeopyle and regularly spaced processes with relatively broad bases and aculeate process tips. Molecular phylogenetic analyses of large and small subunit (LSU and SSU) rDNA sequences demonstrated a close affinity of this species to A. minutum; however, the relatively high level of sequence conservation in dinoflagellate rDNA sequences made these particular markers inadequate for distinguishing one species from the other. Sediment-trap data suggest that A. saanichi has a preference for cooler temperatures and lowered salinities. (C) 2012 Elsevier B.V. All rights reserved.

The toxic dinoflagellate <i>Cochlodinium polykrikoides</i> (Dinophyceae) produces resting cysts	HARMFUL ALGAE			English	Article						Bloom initiation; Bloom expansion; Cochlodinium polykrikoides; Encystment; Excystment; Germination; Harmful algal bloom (HAB); Resting cyst	HARMFUL ALGAL BLOOMS; DIURNAL VERTICAL MIGRATION; RED TIDE BLOOMS; LONG-ISLAND; UNARMORED DINOFLAGELLATE; GONYAULAX-TAMARENSIS; SURFACE SEDIMENTS; COASTAL WATERS; NEW-YORK; GYMNODINIALES	While harmful algal blooms (HABs) caused by the toxic dinoflagellate Cochlodinium polykrikoides have been known to science for more than a century, the past two decades have witnessed an extraordinary expansion of these events across Asia, North America, and even Europe. Although the production of resting cysts and subsequent transport via ships' ballast water or/and the transfer of shellfish stocks could facilitate this expansion, confirmative evidence for cyst production by C. polykrikoides is not available. Here, we provide visual confirmation of the production of resting cysts by C. polykrikoides in laboratory cultures isolated from North America. Evidence includes sexually mating cell pairs, planozygotes with two longitudinal flagella, formation of both pellicular (temporary) cysts and resting cysts, and a time series of the cyst germination process. Resting cyst germination occurred up to 1 month after cyst formation and 2-40% of resting cysts were successfully germinated in cultures maintained at 18-21 degrees C. Pellicular cysts with hyaline membranes were generally larger than resting cysts, displayed discernable cingulum and/or sulcus, and reverted to vegetative cells within 24 h to similar to 1 week of formation. A putative armored stage of C. polykrikoides was not observed during any life cycle stage in this study. This definitive evidence of resting cyst production by C polykrikoides provides a mechanism to account for the recurrence of annual blooms in given locales as well as the global expansion of C. polykrikoides blooms during the past two decades.

The establishment of algal strains collected at multiple localities is necessary for a rigorous study of taxonomy, morphology and evolution in these unicellular organisms. We collected sediment and water tow samples from more than 60 localities in coastal areas of the eastern Mediterranean Sea and documented 15 morphospecies of calcareous dinophytes. Internal transcribed spacer (ITS) barcoding identified numerous species of the Scrippsiella trochoidea species complex that were genetically distinct, but indistinguishable in gross morphology (i.e. with the same tabulation patterns of the motile theca and similar spiny coccoid stages). We assessed a possible minimal number of cryptic species using ITS ribotype networks that indicated the existence of at least 21 species within the Scrippsiella trochoidea species complex. Species diversity of calcareous dinophytes appears higher in the Mediterranean Sea than in other parts of the world's oceans such as the North Sea. Our data underline the importance of field work to record the diversity of calcareous dinophytes and other unicellular life forms.

However, the recognition of a eutrophication signal in dinocyst records is ambiguous. In addition, as few studies have focussed on the climate signal as recorded by dinocyst proxies over a moderately short time scale, a moderately short temporal record of dinocysts in sediments from two cores recovered in the Changjiang estuary, East China Sea was investigated. Total cyst concentrations and Paralytic Shellfish Poison (PSP) cyst concentrations increased with eutrophication, and total cyst concentrations, run-off from the Changjiang River and Oceanic Nino Index peaks co-occurred. Total cyst concentrations and PSP cyst concentrations may be a potential eutrophication signal in subtropical estuaries and the climate signal could be recorded in the cyst assemblages in estuaries within a moderately short time scale as the run-off from rivers and their nutrient load changed over time.

The majority of their coccoid stages are cryptotabulate or entirely atabulate, whereas relatively few forms exhibit at least some degree of tabulation more than the archeopyle. A survey of coastal surface sediment samples from the Mediterranean Sea resulted in the isolation and cultivation of several strains of calcareous dinophytes showing a prominent tabulation. We investigated the morphologies of the thecate and the coccoid cells and conducted phylogenetic analyses using Maximum Likelihood and Bayesian approaches. The coccoid cells showed a distinct reflection of the cingulum (and were thus cingulotabulate), whereas thecal morphology corresponded to the widely distributed and species-rich Scrippsiella. As inferred from molecular sequence data (including 81 new GenBank entries), the strains belonged to the Scrippsiella sensu lato clade of the Thoracosphaeraceae and represented two distinct species. Morphological details likewise indicated two distinct species with previously unknown coccoid cells that we describe here as new, namely S. bicarinata spec. nov. and S. kirschiae spec. nov. Cingulotabulation results from the fusion of processes representing the pre- and postcingular plate series in S. bicarinata, whereas the ridges represent sutures between the cingulum and the pre- and postcingular series in S. kirschiae, respectively. Bicarinate cingulotabulation appears homoplasious among calcareous dinophytes, which is further supported by a comparison to similar, but only distantly related fossil forms.

The average process length showed a significant inverse relation to annual seawater density: st annual?=?-0.8674 x average process length?+?1029.3 (R2?=?0.84), with a standard error of 0.78?kg?m-3. A sediment trap study from Effingham Inlet in British Columbia revealed the same relationship between average process length and local seawater density variations. In the BalticSkagerrak region, the average process length variation was related significantly to annual seawater density: st annual?=?3.5457 x average process length?-?993.28 (R2?=?0.86), with a standard error of 3.09?kg?m-3. These calibrations cannot be reconciled, which accentuates the regional character of the calibrations. This can be related to variations in molecular data (small subunit, long subunit and internal transcribed spacer sequences), which show the presence of several genotypes and the occurrence of pseudo-cryptic speciation within this species.

The naturally occurring radionuclide Pb-210 activity in the sediment samples were measured; and subsequently the sedimentation rates (SRs) and ages were modeled. The SRs ranged from 0.15 +/- 0.01 to 2.80 +/- 0.38 cm/yr and provided coverage of time period spanning between 21 and 145 yr. Cysts of potential harmful dinoflagellates (Gonyaulax spinifera, Lingulodinium polyedrum, Protoceratium reticulatum and Scrippsiella trochoidea) were observed to be present earlier than the 20th century. Among the four sediment cores, significant temporal variations in cyst abundance were observed in the sediment core, off Mangalore. Two of the cores from off Mangalore and Cannanore were dominated by autotrophic cyst assemblages (Gonyaulax membranacea and Gonyaulax spinifera) in the deeper sediment sections. However, the upper sediment sections were dominated by heterotrophic forms. Temporal shifts in cyst assemblages from autotrophic to heterotrophic dinoflagellates in the Mangalore core coincided with high deposition of shells; carbon analyses (delta C-13(org) and C-org:N ratio) revealed shifts in organic matter type from terrestrial to marine source. The terrigenous input in this region, influenced by the monsoonal variations, can thus affect dinoflagellate assemblage structure and lead to changes in ecosystem functioning. (c) 2012 Elsevier B.V.

Thirty-two dinoflagellate cyst taxa were identified in the sediment trap samples, and the dinoflagellate cyst assemblages were found to be dominated by cysts of Polykrikos kofoidii, Scrippsiella trochoidea, Protoperidinium spp., Polykrikos schwartzii, Gymnodinium catenatum and Ensiculifera carinata. The flux of dinoflagellate cysts ranged from 0.10 x 10(5) to 35.97 x 10(5) cysts m(-2) day(-1), and the highest flux occurred during summer, and was driven completely by the flux in the production of P. kofoidii and P. schwartzii cysts. The timing of the production of cysts of Polykrikos species seemed to be related to the appearance of G. catenatum as prey. The assemblages of dinoflagellate cysts in surface sediments from Gamak Bay, and their seasonal changes, were very similar to those in the sediment trap samples, which suggested that the monitoring of dinoflagellate cysts in sediment samples can provide information on the environmental conditions in Gamak Bay.

Chen et al. are described: B. alyeolata, B. spinosa and B. tarfayensis. The diagnosis of the genus Bosedinia is emended to include forms with an alveolate wall and/or hair-like spiny processes. The appearance in massive blooms across considerable section intervals closely related to and within oceanic anoxic event 2 (Cenomanian-Turonian) and anoxic event 3 (Coniacian-Santonian) suggests episodic salinity stratification as important aspect for enhanced organic carbon accumulation.

In this study we investigate the effects of different processing techniques on dinoflagellate cyst concentrations using well-mixed sediment samples from Saanich Inlet, British Columbia, Canada. At the onset of any dinoflagellate cyst investigation, we suggest following the recommendations of Maher (1981) to experimentally adjust the sample size to obtain a ratio close to similar to 2 of dinoflagellate cysts counted to Lycopodium spores counted, in order to obtain reproducible concentrations. Results further show that both oven-drying at similar to 45 degrees C and freeze-drying are viable, non-destructive techniques yielding reproducible results. Use of warm HCl (40-60 degrees C) for a short time (30 min) is harmless, whereas treatment with warm HF (40-60 degrees C) affects the reproducibility of the concentrations. Pre-sieving can result in loss of cysts and/or spike but this can be easily monitored by checking the residue. Perforated metal sieves show more consistent results than the Nitex nylon meshes. The use of 30 second sonication does not affect the reproducibility, and is advised to remove amorphous organic matter. Adding the Lycopodium spike at the end of preparation yields consistently lower concentrations, which were usually not reproducible, suggesting noticeable losses of Lycopodium spores during processing if the Lycopodium spores are added at the beginning. This method can be considered a viable alternative, but the discrepancy should be taken into account. (C) 2012 Elsevier B.V. All rights reserved.

PST profiles were significantly different between life stages; the two gonyautoxins GTX1 and 2 were present in vegetative and senescent cells, but disappeared from gametes and zygotes. Toxin-profile changes were shown to occur very quickly in both strains when pellicle cyst formation was induced by shaking (four minutes) followed by rinsing on a screen. These pellicle cysts produced from exponentially-growing, vegetative cells lost GTX1 and 2 completely. Rapid toxin epimerization of GTX1 to GTX4 and GTX2 to GTX3 is one possible explanation, although the biological advantage of this remains unclear. Another possible explanation is that during the mating phase of a bloom or when cells are disturbed, GTX1 and GTX2 are released into the surrounding water. It may be advantageous for a dinoflagellate bloom to be surrounded by free toxins in the water. (c) 2012 Elsevier B.V. All rights reserved.

The fluorescence intensity was strong enough to allow discrimination between positive and negative results by naked eye under a UV lamp, even in amplified samples from a single cell, by using the LAMP method. Unambiguous detection by naked eye was possible even in half the volume of LAMP cocktail recommended by the manufacturer, suggesting the potential to significantly reduce the cost of Alexandrium monitoring. Therefore, we can conclude that this method is one of the most convenient, sensitive, and cost-effective molecular tools for Alexandrium monitoring. (C) 2012 Elsevier B.V. All rights reserved.

This was based on surveys conducted in two seasons in pre- and post-monsoons, and on observations for both plankton and cyst assemblages. In the plankton samples, 57 and 26 dinoflagellate species were recorded, respectively, in the pre- and post-monsoons. Among the list from plankton and cyst samples, harmful species were found: red-tide species including Prorocentrum spp. and Alexandrium affine, and causative species of paralytic shellfish poisoning, e.g., Alexandrium tamiyavanichii and Gymnodinium catenatum, and of diarrhetic shellfish poisoning, e.g., Dinophysis spp. Therefore, although no incidences have been reported yet, attention must be paid to these harmful algal bloom (HAB) events in Myanmar where exploitation of fishery resources is drastically increasing. Other dinoflagellate compositions were also unique and may relate to the oceanographic system in this region. In the pre-monsoon, rather rare oceanic species of Ornithocercus spp. were found concurrently with neritic species, probably due to the extensive southwesterly current from the Indian Ocean. Throughout the seasons, diverse species of Protoperidinium were predominately recorded in both planktonic and sediment samples, indicating richness of prey organisms probably sustained by upwelling systems.

In this study, we examined 4 methods for extracting DNA from single resting cysts of A. tamarense and A. catenella to obtain more stable and better amplification success and to facilitate unambiguous detection using the LAMP method. Apart from comparing the 4 different DNA extraction methods, namely, (1) boiling in Tris-EDTA (TE) buffer, (2) heating at 65 degrees C in hexadecyltrimethylammonium bromide buffer, (3) boiling in 0.5% Chelex buffer, and (4) boiling in 5% Chelex buffer, we also examined the need for homogenization to crush the resting cysts before DNA extraction in each method. Homogenization of resting cysts was found to be essential for DNA extraction in all 4 methods. The detection time was significantly shorter in 5% Chelex buffer than in the other buffers and the amplification success was 100% (65/65), indicating the importance of DNA extraction and the effectiveness of 5% Chelex buffer in the Alexandrium LAMP.

Aerobic degradation of organic carbon inferred from dinoflagellate cyst decomposition in Southern Ocean sediments	QUATERNARY RESEARCH			English	Article						Organic-walled dinoflagellate cysts; Oxygen; Organic carbon; Degradation	EASTERN ATLANTIC SECTOR; OXYGEN EXPOSURE TIME; SURFACE SEDIMENTS; FALKLAND TROUGH; PRESERVATION; MATTER; SEA; WEDDELL; SCOTIA; MODEL	Organic carbon (OC) burial is an important process influencing atmospheric CO2 concentration and global climate change; therefore it is essential to obtain information on the factors determining its preservation. The Southern Ocean (SO) is believed to play an important role in sequestering CO2 from the atmosphere via burial of OC. Here we investigate the degradation of organic-walled dinoflagellate cysts (dinocysts) in two short cores from the SO to obtain information on the factors influencing OC preservation. On the basis of the calculated degradation index kt, we conclude that both cores are affected by species-selective aerobic degradation of dinocysts. Further, we calculate a degradation constant k using oxygen exposure time derived from the ages of our cores. The constant k displays a strong relationship with pore-water O-2, suggesting that decomposition of OC is dependent on both the bottom- and pore-water O-2 concentrations.

ENVIRONMENTAL SCIENCE & TECHNOLOGY			English	Article							HARMFUL ALGAL BLOOMS; BAHAMENSE VAR. COMPRESSUM; MANILA BAY	Some microplanktonic species, mostly dinoflagellates, causing Harmful Algal Blooms (HABs), produce toxins which may affect the environment and human health, thus causing important economic losses. The dinoflagellate Pyrodinium bahamense var. compressum is one of the main species causing harmful algal blooms along the tropical Pacific. Although it was first reported along the Mexican coast in the 1970s, here we report that a sedimentary record of Pyrodinium cysts from the Gulf of Tehuantepec in the tropical East Pacific (Mexico), which spans from the 1860s, showed the continuous occurrence of Pyrodinium cysts and that their presence has been declining in the last few decades. Although Pyrodinium HABs have been attributed to El Nino events in the tropical Indo-West Pacific, the record shows that most blooms in the tropical East Pacific appear in periods of low sea surface temperature and higher rainfall, as can be observed during rapid shifts from cold (La Nina) to warm (El Nino) conditions in that region. This mechanism offers new ways to better predict and facilitate early detection of Pyrodinium HABs worldwide.

The structures of three metabolites of the algal hepatotoxin okadaic acid produced by oxidation with human cytochrome P450	BIOORGANIC & MEDICINAL CHEMISTRY			English	Article						Okadaic acid; Dinoflagellate; Algal toxin; Xenobiotic metabolism; Cytochrome P450	ASSAY	Four metabolites of okadaic acid were generated by incubation with human recombinant cytochrome P450 3A4. The structures of two of the four metabolites have been determined by MS/MS experiments and 1D and 2D NMR methods using 94 and 133 mu g of each metabolite. The structure of a third metabolite was determined by oxidation to a metabolite of known structure. Like okadaic acid, the metabolites are inhibitors of protein phosphatase PP2A.

In this study, a cost-effective electrochemical disinfection reactor was developed to inactivate Escherichia coli, one of the IMO-regulated indicator microbes, in simulated ballast water. The complete inactivation of E. coli could be achieved within a very short time (150, 120, or 60 s) with an energy consumption as low as 0.0090, 0.0074 or 0.0035 kWh/m(3) for ballast water containing E. coli at concentrations of 10(8), 10(7) and 10(6) CFU/100 mL, respectively. Electrochemical chlorination was the major disinfection mechanism in chloride-abundant electrolytes, whereas oxidants such as ozone and free radicals contributed to 20% of the disinfection efficiency in chloride-free electrolytes. Moreover, a disinfection kinetics model was successfully developed to describe the inactivation of E. coli. (C) 2012 Elsevier Ltd. All rights reserved.	[Nanayakkara, K. G. Nadeeshani; Alam, A. K. M.

Asexual division took place in the motile stage by the sharing of theca (desmoschisis). High cell-size variability and differences in division capability were detected in the cultures. Thecal analyses and nuclear division patterns allowed characterization of the different phases of dividing cells obtained during an in situ cell-cycle sampling performed off Llavaneres beach (Northeast Spain). During the 45-h cycle, binucleated cells accounted for 2.6% of the population. Division was initiated with the onset of dusk and reached a maximum 3-4 h before dawn. No dividing cells were detected after 09:00 AM. Sexuality occurred both in cultures and in natural populations of O. cf. ovata. Mating gamete pairs were the only sexual stages that could be distinguished from vegetative stages. The differences between these pairs and dividing cells are described herein. None of the individually isolated gamete pairs underwent fusion nor encystment, instead, in most of them one member of the gamete pair divided. Rather than plasmogamy, there was evidence of nuclear migration from one gamete to the other. Pellicle cysts, thin-walled cysts, and thecate cysts were also identified and studied. These cysts, embedded in abundant mucilage in a bloom-derived incubated sample, were able to germinate for as long as 6 months after their formation. Our results suggest that they constitute the overwintering population that causes recurrent blooms of O. cf. ovata in some areas of the Mediterranean Sea. (C) 2012 Elsevier By. All rights reserved.

An Alexandrium Spp. Cyst Record from Sequim Bay, Washington State, USA, and its Relation to Past Climate Variability	JOURNAL OF PHYCOLOGY			English	Article						Alexandrium; climate change; dinoflagellate cysts; Puget Sound; sea surface temperature; Sequim Bay	HARMFUL ALGAL BLOOMS; PARALYTIC SHELLFISH; PUGET-SOUND; GEODUCK CLAMS; RESTING CYSTS; TOXINS; ACCUMULATION; DINOPHYCEAE; OSCILLATION; CATENELLA	Since the 1970s, Puget Sound, Washington State, USA, has experienced an increase in detections of paralytic shellfish toxins (PSTs) in shellfish due to blooms of the harmful dinoflagellate Alexandrium. Natural patterns of climate variability, such as the Pacific Decadal Oscillation (PDO), and changes in local environmental factors, such as sea surface temperature (SST) and air temperature, have been linked to the observed increase in PSTs. However, the lack of observations of PSTs in shellfish prior to the 1950s has inhibited statistical assessments of longer-term trends in climate and environmental conditions on Alexandrium blooms. After a bloom, Alexandrium cells can enter a dormant cyst stage, which settles on the seafloor and then becomes entrained into the sedimentary record. In this study, we created a record of Alexandrium spp. cysts from a sediment core obtained from Sequim Bay, Puget Sound. Cyst abundances ranged from 0 to 400 cysts . cm-3 and were detected down-core to a depth of 100 cm, indicating that Alexandrium has been present in Sequim Bay since at least the late 1800s. The cyst record allowed us to statistically examine relationships with available environmental parameters over the past century. Local air temperature and sea surface temperature were positively and significantly correlated with cyst abundances from the late 1800s to 2005; no significant relationship was found between PDO and cyst abundances. This finding suggests that local environmental variations more strongly influence Alexandrium population dynamics in Puget Sound when compared to large-scale changes.

Species in this genus are regular members of the epiphytic community in tropical seas but their geographic range have shown an apparent expansion towards temperate regions in recent years. This is the case of the Mediterranean Sea, where Ostreopsis cf. ovata is responsible for intense blooms in summer and autumn. With the aim of describing the growth performances of O. cf. ovata, we carried out a multifactorial experiment in which strains isolated from 3 locations along the Italian coast were grown at different combinations of temperature, daylength and irradiance encompassing different seasonal conditions. Temperature constiained growth of O. cf. ovata within a window of 18-30 degrees C, while best performances were recorded at 22 and 26 degrees C. Growth was maximum at 12 h daylength, whereas it was limited by photon flux density at short daylength (9 h) and often showed photosaturation at the longest daylength (15 h). Cells with anomalous shape were found during the exponential phase at the lowest and highest temperatures, while cells with a reduced size were produced at all conditions except 18 degrees C. Total toxin concentration varied between the different environmental conditions and between exponential and post-exponential growth phases without a clear pattern, whereas toxin composition was less variable. Our results suggest that O. cf. ovata is adapted to intermediate temperatures and daylength conditions such as those recorded in the natural environment at the beginning of summer and/or at the beginning of autumn, when this dinoflagellate builds up its biomass along the coast of the Mediterranean Sea. Photosaturation instead occurs at the highest temperature and irradiance conditions, thus supporting the observations of generally lower cell abundances in late July-August. (C) 2012 Elsevier B.V.

On the West coast of the Iberian Peninsula, toxic blooms have been reported since the mid-1970s. While the recent geographical spread of this species into Australasia has been attributed to human-mediated introduction, its origin in the Northeast Atlantic is still under debate. Gymnodinium catenatum forms a highly resistant resting stage (cyst) that can be preserved in coastal sediments, building-up an historical record of the species. Similar cyst types (termed microreticulate) are produced by other non-toxic Gymnodinium species that often co-occur with G. catenatum. We analysed the cyst record of microreticulate species in dated sediment cores from the West Iberian shelf covering the past ca. 150 years. Three distinct morphotypes were identified on the basis of cyst diameter and paracingulum reticulation. These were attributed to G. catenatum (35.6-53.3 mu m), G. nolleri (23.1-36.4 mu m), and G. microreticulatum (20.5-34.3 mu m). Our results indicate that G. catenatum is new to the NE Atlantic, where it appeared by 1,889 +/- A 10, expanding northwards along the West Iberian coast. The earliest record is from the southernmost sample, while in the central Portuguese shelf the species appears in sediments dated to 1,933 +/- A 3, and in the North, off Oporto, in 1,951 +/- A 4. On the basis of the cyst record and toxic bloom reports, we reconstruct the invasive pathway of G. catenatum in the NE Atlantic. Although human-mediated introduction cannot be discarded, the available evidence points towards natural range expansion, possibly from NW Africa.

Morphology and Phylogeny of <i>Scrippsiella trochoidea</i> (Dinophyceae) a potentially harmful bloom forming species isolated from the sediments of Iran's south coast	IRANIAN JOURNAL OF FISHERIES SCIENCES			English	Article						Cyst; Iran south coast; Molecular analysis; Morphology; Phylogeny; Scrippsiella trochoidea; Sediment; Vegetative cell	SP-NOV DINOPHYCEAE; CYST PRODUCTION; DINOFLAGELLATE; CALCIODINELLOIDEAE; IDENTIFICATION; PERIDINIALES; GULF	Phytoplankton cells and resting cysts of the species Scrippsiella trochoidea are regular and dominant components of the dinoflagellate flora of coastal marine waters and sediments around the world. This species is a common harmful bloom forming species in coastal waters. In this study, for the first time cyst of S. trochoidea were isolated from the sediments of southeast coast of Iran. Five strains from the germination of a single cyst belonged to S. trochoidea. In order to confirm identification of the species an excystment and encystment experiment, cyst and germinated cell morphology and plate pattern by light and electron microscopy (SEM) have been described. The nucleotide sequences of two highly diverse regions, the rDNA-ITS 1,2 and 5.8S-rDNA have been sequenced for all strains. Homologous sequences from GenBank with five Iranian strains were compared to find their phylogenetic relationship. Both NJ and MP phylogenetic and morphological analysis showed five strains of S. trochoidea from Iran were clustered with previously described S. trochoidea and Calciodinellum levantinum species, and its closest relationship was with Scrippsiella sp. strain with a 1.2-1.4% sequence divergence. Results indicate that molecular studies of rDNA if combined with morphological cyst and vegetative cells could be a valuable approach to identification and taxonomy of calciodinelloideae dinoflagellate.

In this study, in situ excystment and encystment were monitored during recurrent Alexandrium minutum blooms in Arenys de Mar harbor (NW Mediterranean Sea) from October 2005 to May 2008. In addition, the dynamics of vegetative cells in the water column and resting cysts in the sediments were assessed. Excystment occurred continuously during the period studied. The excystment fluxes and the estimated excystment percentages indicated a pattern of alternating reduced and active excystment periods. From July to November, excystment percentages were <0.1%, whereas from December to June the A. minutum population underwent active excystment, with excystment percentages of 0.3-45.7%. Periods of active excystment coincided with increases in irradiance and water temperature, conditions also favorable for bloom development. During vegetative cell blooms, resting cyst formation coincided with periods marked by vegetative cell abundances in the water column of >2 x 10(3) cells l(-1). Resting cyst fluxes were higher when the abundance of vegetative cells in the overlying water column was greater. The excystment and encystment processes overlapped for 2 months during the extended blooms, indicating that newly formed resting cysts had overcome the mandatory dormancy period and were capable of germinating within the same bloom in which they were produced. Resting cysts in the surface sediment were rapidly depleted during periods of active excystment, but their production, although involving only a small fraction of the vegetative population, more than compensated for their loss. These results are discussed with respect to the role of frequent life-stage switches in determining the population dynamics and the maintenance of A. minutum blooms. (C) 2012 Elsevier B.V.

Life-cycle stages of the toxic dinoflagellate Alexandrium fundyense were monitored both in the water column and in the sediments from the onset to the decline of a bloom in Northport Harbor (New York, USA). Moreover, excystment and encystment were investigated in situ through the deployment of emergence and sediment traps, respectively. The bloom, the largest ever recorded on the east coast of the US south of Massachusetts, persisted for 6 weeks between April and June 2008, and reached maximum vegetative cell abundances of 1.3 x 10(6) cells l(-1). Resting cysts in the surface sediments were quantified at the onset of the bloom, all of which germinated during the development of the bloom. Excystment of these resting cysts provided inoculum of vegetative cells for bloom development. In the water column, first detection of planozygotes occurred during the exponential phase of the bloom at vegetative cell abundances of similar to 10(4) cells l(-1). Nonmotile planozygotes and resting cysts were observed in the sediment traps before the first peak of vegetative cells, coinciding with the detection of planktonic planozygotes. The estimated encystment and planozygote percentages were relatively low, indicating that a small proportion of the vegetative cell population was involved in sexual reproduction. However, encystment was a crucial process for replenishing the cyst stock of the A. fundyense population in the sediments as cyst densities were low before the bloom but high after it. For the first time, formation of pellicle cysts in the field by A. fundyense was observed, which coincided with high vegetative cell abundances in the water column during the bloom.

The population. dynamics and spatial distribution of the species were studied in the Foglo archipelago, a bloom area in Aland, northern Baltic Sea. During a two-year survey, cell and toxin concentrations of A. ostenfeldii were recorded in summer phytoplankton communities and related to environmental parameters. The studies revealed that A. ostenfeldii blooms were restricted to a small area in a narrow sound, where cells of this species were detected from May to September in 2009 and 2010. A. ostenfeldii proliferated to bloom concentrations (1.7-2.1 x 10(5) cells L-1) only at water temperatures around 20 degrees C during warm periods in July and August. Abundance of A. ostenfeldii did not significantly correlate with dissolved inorganic nutrient concentrations (p = 0.4-0.6) but was related to high concentrations of resting cysts in the sediment (p < 0.001). The blooms were not monospecific but A. ostenfeldii was a part of a diverse productive phytoplankton community forming 30-60% of the total biomass during the abundance peaks. This study provides the first evidence of paralytic shellfish poisoning (PSP) toxins produced by dinoflagellate blooms in the Baltic Sea: PSP toxin dynamics correlated with the progression of the A. ostenfeldii bloom with toxin peaks mirroring the species abundance peaks. No other potentially toxic species were identified from the phytoplankton community. PSP toxin concentrations of up to 2.3 mu g L-1 measured in the A. ostenfeldii cell fraction suggest that blooms may have toxic effects on co-occurring biota. (C) 2011 Elsevier B.V.

Thirty-five dinoflagellate cyst taxa belonging to 15 genera and 3 unknown cysts were identified and quantified at 22 sampling sites. Autotrophic cysts (e.g., Spiniferites bentori var. truncata) and heterotrophic cysts (Brigantedinium sp.1 and Quinquecuspis concreta) dominated the sediment samples. The spatial distribution of cyst abundance showed a significant positive correlation with increased nutrients, but was negative to heavy metal pollution. The highest cyst abundance (with an average of 539 cysts g(-1) DW) occurred in Zone A, corresponding to nutrient enrichment caused by domestic sewage discharge. In contrast, the lowest cyst abundance (with an average of 131 cysts g-1 DW) occurred in Zone E. impacted heavily by the industrial pollution. The abundance of autotrophic cysts decreased dramatically in Zone E compared with heterotrophic cysts and showed a sensitivity to industrial pollution. How heavy metals affect physiological mechanisms in autotrophic and heterotrophic cysts differentially is in need of in-depth study. (C) 2011 Elsevier B.V. All rights reserved.

The ability of Alexandrium to colonize multiple habitats and to persist over large regions through time is testimony to the adaptability and resilience of this group of species. Three different families of toxins, as well as an as yet incompletely characterized suite of allelochemicals are produced among Alexandrium species. Nutritional strategies are equally diverse, including the ability to utilize a range of inorganic and organic nutrient sources, and feeding by ingestion of other organisms. Many Alexandrium species have complex life histories that include sexuality and often, but not always, cyst formation, which is characteristic of a meroplanktonic life strategy and offers considerable ecological advantages. Due to the public health and ecosystem impacts of Alexandrium blooms, the genus has been extensively studied, and there exists a broad knowledge base that ranges from taxonomy and phylogeny through genomics and toxin biosynthesis to bloom dynamics and modeling. Here we present a review of the genus Alexandrium, focusing on the major toxic and otherwise harmful species. (C) 2011 Elsevier B.V. All rights reserved.

The distribution of Chattonella species was confirmed in tropical, subtropical and temperate regions in the world accompanying mass mortalities of fishes in nature and in aquaculture. The fish-killing mechanisms are still unclear, but suffocation is the ultimate cause of fish death. Increasing evidence is pointing towards the generation of reactive oxygen species (ROS, e.g. superoxide), which are responsible for the gill tissue injury and mucus production that leads to death of fishes. A taxonomic revision was proposed based on morphology and genetic diversity that Chattonella antiqua and Chattonella ovata should be varieties of Chattonella marina possessing nomenclatural priority. Optimum temperatures for growth are 25 degrees C for C. antiqua and C. marina, 25-30 degrees C for C. ovata and 20-30 degrees C for Chattonelia subsalsa. Adequate ranges of salinity for growth were about 20-30 for Chattonella species. Chattonella cells generally divide once a day. Laboratory culture experiments with artificial synthetic medium demonstrated that C antiqua, C. marina and C ovata used only Fe chelated with EDTA for growth, although tested diatoms and dinoflagellates used rather many kinds of chelated Fe. A suitable concentration of humic acid supplied with iron also had enhancing effects on the growth of C. antiqua. Diel vertical migration was observed in Chattonella, and the cells reached 7.5 m deep at night in the case of C. antiqua demonstrated by a mesocosm experiment in the Seto Inland Sea. Chattonella species have diplontic life history and have haploid cyst stage in their life cycle. Encystment was observed through formation of pre-encystment small cells after the depletion of nitrogen, and the small cells sink to the sea bottom to complete cyst formation by attachment to the solid surface such as diatom frustules and sand grains. Newly formed cysts are in the state of spontaneous dormancy and they need cold temperature period of four months or longer for maturation (acquisition of germination ability). Cysts germinate in early summer and resultant vegetative cells play an important role as seed populations in blooming in the summer season. However, relatively small part of cyst populations actually germinate from bottom sediments, and success of red tide formation is dependent on the growth in water columns. Since red tides of Chattonella were observed when diatoms were scarce in seawater, diatoms appear to have a key for the predominance of Chattonella in water columns. Diatom resting stages in sediments need light for germination/rejuvenation, whereas Chattonella cysts can germinate even in the dark, implying the selective germination of Chattonella cysts at the sea bottom under calm oceanographic conditions which contribute to bloom formation of Chattonella. As a mechanism of red tide occurrences of Chattonella in coastal sea, "diatom resting hypothesis" was presented. Biological control using diatoms is proposed through the germination/rejuvenation of resting stages suspending from bottom sediments to euphotic layer by sediment perturbation with submarine tractors or fishing trawling gears. Since diatoms have much higher growth rates, and newly joined diatom vegetative cells grow faster and prevent occurrence of Chattonella red tides as a result. As another prevention strategy for Chattonella red tides, algicidal bacteria inhabiting in seaweed beds and seagrass beds are presented. Co-culture of fish and seaweeds in aquaculture areas, and the developments of seaweed- and seagrass-beds would be practical and ultimately environment-friendly strategies for the prevention of harmful red tides of Chattonella by virtue of natural algicidal bacteria supplied from seaweeds and leaves of seagrass.

Global toxicology, ecophysiology and population relationships of the chainforming PST dinoflagellate <i>Gymnodinium catenatum</i>	HARMFUL ALGAE			English	Review						Gymnodinium catenatum; Paralytic Shellfish Toxin profiles; Molecular Biogeography; Bloom Ecophysiology	SP-NOV DINOPHYCEAE; GULF-OF-CALIFORNIA; PARALYTIC SHELLFISH TOXINS; RECENT MARINE-SEDIMENTS; RED TIDE; MICRORETICULATE CYST; GRAHAM DINOPHYCEAE; BAHIA-CONCEPCION; BALLAST WATER; HIROSHIMA BAY	Increasing scientific awareness since the 1980s of the chain-forming dinoflagellate Gymnodinium catenatum has led to this species being reported with increased frequency in a globally increasing number of countries (23 at present). G. catenatum exhibits little molecular genetic variation in rDNA over its global range, in contrast to RAPD fingerprinting which points to high genetic variation within regional populations even between estuaries 50 km apart. All Australian and New Zealand strains possess a thymine nucleotide (T-gene) near the start of the 5.8S rRNA whereas all other global populations examined to date possess cytosine-nucleotide (C-gene), except for southern Japan which harbours both C-gene and T-gene strains. Together with cyst and plankton evidence this strongly suggests that both Australian and New Zealand populations have derived from southern Japan. Global dinoflagellate populations and cultures exhibit an extraordinary variation in PST profiles (STX and 21 analogues), but consistent regional patterns are evident with regard to the production of C1,2; C3,4; B1,2; and neoSTX analogues. PST profiles of cyst-derived cultures are deemed unrepresentative. Distinct ecophysiological differences exist between tropical (21-32 degrees C) and warm-temperate ecotypes (12-18 degrees C), but these appear unrelated to ITS genotypes and PST toxin phenotypes. On current evidence, cyst germination appears to play a minimal role in the bloom dynamics of this species, while seasonal and inter-annual bloom variations result from the physical constraints (temperature and light) on the growth of the dinoflagellates in the water column. G. catenatum exhibits a capacity to utilize many forms of nitrogen. Its chain formation and strong motility allow it to undergo retrieval migrations to exploit light and nutrient resource gradients in both stratified and mixed environments. Subtle strain-level variations in rnicronutrient (Se, humics) requirements and interaction with associated bacterial flora may provide a partial explanation for the contrasting inshore (Tasmanian), and offshore (Spain, Mexico) bloom patterns by the same species in different geographic regions.

COMPRESSUM; COASTAL WATERS; MANILA BAY; DINOPHYCEAE; PLATE; GULF; ALEXANDRIUM	It has been 40 years since the first recorded toxic bloom of Pyrodinium bahamense occurred in Papua New Guinea in 1972. Subsequently this species has increased in importance as a paralytic shellfish poisoning toxin (PSTs) producer in several regions of the world, especially in the Indo-west Pacific. P. bahamense is a thecate tropical/subtropical euryhaline dinoflagellate. Available data indicate that it forms blooms only in waters of 20 psu or higher salinity and at temperatures above 20 degrees C. It is monospecies with two varieties, namely var. compressum and var. bahamense. For many years it was widely accepted that only var. cornpressum is toxic and is limited to the tropical Pacific while var. bahamense is nontoxic and is limited to the tropical Atlantic. It is now known, however, that there are at least two locations where the varieties co-occur and it has also been proven that var. bahamense in Florida waters also produce PST. P. bahamense has a life cycle typical of many dinoflagellates. It has a heterothallic sexual cycle that produces a large spiny spherical resting cyst. The toxicity profile of P. bahamense is also very simple with most isolates producing only dc-STX, STX, neoSTX, B1 and B2 toxins. Further studies are needed in order to resolve the varietal status of the species and also to understand the environmental factors that determine its toxicity and bloom dynamics.

Comprehension of algal genetic differences and associated connectivity is fundamental to understand the geographical scale of adaptation and dispersal pathways of harmful microalgal species. In the present study, we combine A. minutum population genetic analyses based on microsatellites with indirect connectivity (C-i) estimations derived from a general circulation model of the Mediterranean sea. Our results show that four major clusters of genetically homogeneous groups can be identified, loosely corresponding to four regional seas: Adriatic, Ionian, Tyrrhenian and Catalan. Each of the four clusters included a small fraction of mixed and allochthonous genotypes from other Mediterranean areas, but the assignment to one of the four clusters was sufficiently robust as proved by the high ancestry coefficient values displayed by most of the individuals (>84%). The population structure of A. minutum on this scale can be explained by microalgal dispersion following the main regional circulation patterns over successive generations. We hypothesize that limited connectivity among the A. minutum populations results in low gene flow but not in the erosion of variability within the population, as indicated by the high gene diversity values. This study represents a first and new integrated approach, combining both genetic and numerical methods, to characterize and interpret the population structure of a toxic microalgal species. This approach of characterizing genetic population structure and connectivity at a regional scale holds promise for the control and management of the harmful algal bloom events in the Mediterranean Sea.

Generally, deposition took place below the CCD. The major part of the sedimentary succession displays no similarities with coeval deposits of the Northern Calcareous Alps, but can be readily correlated with the Rhenodanubian Group of the Penninic Basin (Rehbreingraben Formation, Lower Varicoloured Marlstone, Reiselsberg Formation, Seisenburg Formation, Kalkgraben Formation, Hallritz Formation). Only one outcrop containing glaucophane bearing sandstone cannot be integrated into the Rhenodanubian Group and might be an equivalent of the Branderfleck Formation of the Northern Calcareous Alps. In any case, the term "Walserberg Series" can be abandoned.

Investigating the roles of intrinsic and extrinsic factors in the blooms of <i>Pyrodinium bahamense</i> var. <i>compressum</i> using an individual-based model	18TH BIENNIAL ISEM CONFERENCE ON ECOLOGICAL MODELLING FOR GLOBAL CHANGE AND COUPLED HUMAN AND NATURAL SYSTEM	Procedia Environmental Sciences		English	Proceedings Paper	18th Biennial ISEM Conference on Ecological Modelling for Global Change and Coupled Human and Natural Systems	SEP 20-23, 2011	Beijing Normal Univ, Beijing, PEOPLES R CHINA	Int Soc Ecol Modelling	Beijing Normal Univ	harmful algal blooms; Pyrodinium; Philippines; biophysical model; individual based model	NITRATE UPTAKE; MANILA BAY; GROWTH; TEMPERATURE; DYNAMICS; MAINE; GULF; DINOFLAGELLATE; PHYTOPLANKTON; PHILIPPINES	Harmful algal blooms are a recurrent, expensive and at times fatal problem plaguing the Philippines. In particular, Sorsogon Bay in the Bicol region has experienced prolonged shellfish bans due to blooms by the Paralytic Shellfish Poisoning causative species Pyrodinium bahamense var. compressum (Pbc). In order to help explore and understand the population dynamics of Pbc in Sorsogon Bay in relation to environmental factors, an individual-based model has been developed. This model accounts for key life history processes (reproduction, mortality, encystment, excystment) in a spatially-explicit setting. Vegetative cells and resting cysts are separately represented. Movement is due to advection rates from a 3D hydrodynamic model, as well as sinking rates. Asexual reproduction (population growth) occurs in response to light, temperature, salinity and nutrient conditions where the cells are spatially situated. Encystment and excystment processes are also spatially-explicit based on intrinsic factors, and environmental factors. Grazing effects on blooms are also being explored in the model. Results from field studies in the past years indicate that Pbc blooms develop a few months after the onset of rains, relatively lower temperature, and stratification of the water column. Pronounced blooms are observed at a particular time of the year and in certain areas of the Bay. Bloom formation patterns in the model are compared with these field results. This model will be used to further investigate the conditions leading to blooms and their decline, specifically the roles of transport, stratification, nutrients, cyst dynamics, and grazing on Pbc blooms in Sorsogon Bay.

Recent Technologies for Ballast Water Treatment	OZONE-SCIENCE & ENGINEERING			English	Article						IMO; International Marine Organization (IMO); Ballast water; Bioinvasions; Treatment; disinfection	CRUMB RUBBER FILTRATION; DIAPAUSING EGGS; DINOFLAGELLATE CYSTS; OZONE TREATMENT; GREAT-LAKES; SHIPS; RISK; BIOCIDES; EXCHANGE; EFFICACY	Concern about ballast-mediated bioinvasions into freshwater, estuarine and marine habitats is not limited to biodiversity per se but extends to its broader socio-economic impacts on agriculture, forests, fisheries, aquaculture, and other human activities dependent on the stability of living resources in a particular ecosystem. As a result, invasive species pose almost incalculable economic, socio-cultural and human health security risks. The importance of biological invasions was brought into greater focus as several devastating introductions in many countries occurred and given the limitations of the IMO (International Marine Organization) Guidelines. Consequently the International Convention for the Control and Management of Ships' Ballast Water and Sediments was prepared and was adopted in a Diplomatic Conference in 2004. This Convention aimed to prevent, minimize and ultimately eliminate the risks to the environment, human health, property and resources arising from the transfer of harmful aquatic organisms and pathogens via ships' ballast waters. This article describes recent ballast water treatment studies from scientific and academic community since the last IMO Convention in 2004, and the treatment that received basic and final approval by IMO. We examined different methods available on scientific media to treat ballast water (lab-scale and field-scale tests) and we concluded that a standardization of ballast water treatment still to be done to ensure the IMO Standard.

Diatoms were characterised morphologically (SEM) and genetically (ITS and rbeL DNA fragments) using one intact cell or a clonal chain of cells as a DNA source. Concurrently we monitored the tank physico-chemical environment (temperature, chl a, oxygen, and mineral nutrient concentrations) daily to provide an environmental context for the diatoms that persisted throughout the crossing. Most diatoms perished in ballast tank waters (probably from hypoxia, darkness and pathogens) but a few persisted several days into the voyage and could have been a part of de-ballasted water inocula in the destination port of Vancouver had the voyage been shorter and ballast tank environment more hospitable. New diatoms were taken up onboard with oceanic water during mid-ocean ballast water exchange (including species tolerant of coastal environments, such as Chaetoceros peruvianus) and some of these also persisted for several clays. Taxa recovered from ballast tanks include diatoms considered non-native to other coastal Canadian waters (e.g.. Atlantic coast, such as Coscinodiscus wailesii, Odontella sinensis and Thalassiosira punctigera) and potentially toxigenic species (Pseudo-nitzschia pungens var. aveirensis). Our results illustrate limitations of the benefits of using mid-ocean exchange as a sole means of ballast water management.

Oxidations of organic matter present in the phosphoric acid 54% by the ozone: characterization of groups carbonyls upstream and downstream of the ozonation	MATERIAUX 2010	IOP Conference Series-Materials Science and Engineering		English	Proceedings Paper	National Conference on MATERIAUX	NOV 04-07, 2010	Mahdia, TUNISIA	Tunisian Mat Res Soc-Tu-MRS				This study was focused on the oxidation of organic matter in phosphoric acid 54% by ozone. In order to understand the mechanisms involved in this process, the identification of this matter upstream and downstream of the ozonation was necessary. For the identification, after an extraction by a mixture (dichloro-methanol), the organic phase was divided into two parts: the residue and the extract:-The residue was studied by infrared spectroscopy Fourier Transform (IR-TF). It contains Kerogene which is a mixture of saturated hydrocarbons with high molecular weights. The absorption bands of the FT-IR showed that the residue contains also quantities of amino that correspond to the remains of dinoflagellate cysts, which are abundant in sediments.-The extract has been the subject of a detailed study by, chromatography on silica column, IR-TF spectroscopy and CG-SM. The passage of this extract on a silica column yielded two fractions (saturated fraction and polar fraction). Both of these fractions were analyzed by CG-SM. The yield of the reduction of the organic matter content in the phosphoric acid 54% could not exceed 29%. Therefore, we can conclude that the reduction in the rate of organic matter remains limited by the fact that some compounds are inert towards ozone.

The use of dinoflagellate cysts to separate human-induced from natural variability in the trophic state of the Po River discharge plume over the last two centuries	MARINE POLLUTION BULLETIN			English	Article						Dinoflagellate cyst; Eutrophication; High temporal resolution; Po River; Mediterranean Sea	WESTERN ADRIATIC SEA; ENVIRONMENTAL-FACTORS; TOKYO-BAY; INCREASED EUTROPHICATION; LINGULODINIUM-POLYEDRUM; SPATIAL-DISTRIBUTION; SURFACE SEDIMENTS; COASTAL WATERS; ORGANIC-MATTER; YOKOHAMA-PORT	To obtain insight into the natural and/or human-induced changes in the trophic state of the distal portion of the Po River discharge plume over the last two centuries, high temporal resolution dinoflagellate cyst records were established at three sites. Cyst production rates appear to reflect the natural variability in the river's discharge, whereas cyst associations reflect the trophic state of the upper waters, which in turn can be related to agricultural development. The increased abundances of Lingulodinium machaerophorum and Stelladinium stellatum found as early as 1890 and 1920 correspond to the beginning of the industrial revolution in Italy and the first chemical production and dispersion of ammonia throughout Europe. After 1955, the increased abundances of these species and of Polykrikos schwartzii, Brigantedinium spp. and Pentapharsodinium dalei correspond to agriculturally induced alterations of the hypertrophic conditions. A slight improvement in water quality can be observed from 1987 onward. (C) 2011 Elsevier Ltd. All rights reserved.	[Zonneveld, Karin A.

Revision of the Family Duboscquellidae with Description of Euduboscquella crenulata n. gen., n. sp (Dinoflagellata, Syndinea), an Intracellular Parasite of the Ciliate Favella panamensis Kofoid & Campbell, 1929	JOURNAL OF EUKARYOTIC MICROBIOLOGY			English	Article						Dinoflagellate; parasitism; sexuality; taxonomy; tintinnid	REPRODUCTION	Recent recognition that tintinnids are infected by dinophycean as well as syndinean parasites prompts taxonomic revision of dinoflagellate species that parasitize these ciliates. Long overlooked features of the type species Duboscquella tintinnicola are used to emend the genus and family Duboscquellidae, resulting in both taxa being moved from the Syndinea to the Dinophyceae. Syndinean species previously classified as Duboscquella are relocated to Euduboscquella n. gen., with Euduboscquella crenulata n. sp. as the type. As an endoparasitic species, E. crenulata shares with its congeners processes associated with intracellular development and sporogenesis, but differs from closely related species in nuclear and cortical morphology of the trophont, including a distinctively grooved shield (episome) that imparts a crenulated appearance in optical section. In addition, E. crenulata produces three morphologically distinct spore types, two of which undergo syngamy to form a uninucleate zygote. The zygote undergoes successive division to produce four daughter cells of unequal size, but that resemble the nonmating spore type.	[Coats, D.

An exhaustive bibliographic revision, from 1940 to 2011, was done consulting specialized data analyses, conference meetings, specialized books and manuals. The number of researchers and institutions involved in HAB studies has increased significantly during the last decades, which is reflected in the number and quality of publications. However most of the existing HAB reports are based on sporadic sampling and short-term research programs. Monitoring programs and research activities have focused only in a few HAB species; many toxic and harmful microalgal species have not been considered. To date, there is no laboratory with the capacity and techniques to analyze all the phycotoxins detected in Mexican coasts. Also, many research areas have not been attended adequately in Mexico such as cyst studies, allelophaty, exotic species, effect of climate change, use of molecular tools and teledetection, socioeconomic analyses, and mitigation strategies among others. This review shows that there has been a significantly improvement in the study of HAB in Mexico. However studies are still addressed under an individual and disperse way and lack coordination. Greater achievements would be obtained if we concentrate and coordinate the efforts of researchers and institutions in order to optimize the available resources for HAB studies.

Production of pinnatoxins E, F and G by scrippsielloid dinoflagellates isolated from Franklin Harbour, South Australia	NEW ZEALAND JOURNAL OF MARINE AND FRESHWATER RESEARCH			English	Article						Peridiniales; scrippsielloid; pinnatoxin; toxicity; LC-MS; South Australia		A pinnatoxin producing dinoflagellate was isolated in cyst form from sediments from Franklin Harbour, South Australia, December 2009. One isolate (CAWD180) produced pinnatoxin G, E, F and A (87, 10, 41 and 1.3 pg/cell respectively; liquid chromatograph-mass spectrometer, LC-MS, analysis) and another (CAWD183) produced pinnatoxin G only (13 pg/cell). Australian strains were identical to pinnatoxin E and F producers isolated from Northland, New Zealand (2008), based on large subunit (LSU) rDNA and ITS spacer region sequence data. Cysts were capable of division and produced more toxin per cell than the excysted motile form. Crude extracts of mass cultures were tested for toxicity in mice by intraperitoneal (i.p.) injection, gavage and voluntary consumption, and toxicity ratios were 1.0: 1.8: 4.5 (CAWD180) and 1.0: 2.9: 7.8 (CAWD183). This is similar to the ratios for New Zealand isolates, but differs from other cyclic imines for which oral toxicity can be 10-1000-fold less than i.p. administration.

Dynamics of <i>Alexandrium fundyense</i> blooms and shellfish toxicity in the Nauset Marsh System of Cape Cod (Massachusetts, USA)	HARMFUL ALGAE			English	Article						Paralytic shellfish poisoning; Alexandrium fundyense; Dinoflagellate cysts; Bloom dynamics; Retention mechanism; Nauset Marsh System	DINOFLAGELLATE GONYAULAX-TAMARENSIS; PHYSICAL-BIOLOGICAL MODEL; RED TIDE DINOFLAGELLATE; CYST FORMATION; WESTERN GULF; POPULATION-DYNAMICS; RESTING CYSTS; MAINE; DINOPHYCEAE; BAY	Paralytic Shellfish Poisoning (PSP) toxins are annually recurrent along the Massachusetts coastline (USA), which includes many small embayments and salt ponds. Among these is the Nauset Marsh System (NMS), which has a long history of PSP toxicity. Little is known, however, about the bloom dynamics of the causative organism Alexandrium fundyense within that economically and socially important system. The overall goal of this work was to characterize the distribution and dynamics of A. fundyense blooms within the NMS and adjacent coastal waters by documenting the distribution and abundance of resting cysts and vegetative cells. Cysts were found predominantly in three drowned kettle holes or salt ponds at the distal ends of the NMS - Salt Pond, Mill Pond, and Town Cove. The central region of the NMS had a much lower concentration of cysts. Two types of A. fundyense blooms were observed. One originated entirely within the estuary, seeded by cysts in the three seedbeds. These blooms developed independently of each other and of the A. fundyense population observed in adjacent coastal waters outside the NMS. The temporal development of the blooms was different in the three salt ponds, with initiation differing by as much as 30 days. These differences do not appear to reflect the initial cyst abundances in these locations, and may simply result from higher cell retention and higher nutrient concentrations in Mill Pond, the first site to bloom. Germination of cysts accounted for a small percentage of the peak cell densities in the ponds, so population size was influenced more by the factors affecting growth than by cyst abundance. Subsurface cell aggregation (surface avoidance) limited advection of the vegetative A. fundyense cells out of the salt ponds through the shallow inlet channels. Thus, the upper reaches of the NMS are at the greatest risk for PSP since the highest cyst abundances and cell concentrations were found there. After these localized blooms in the salt ponds peaked and declined, a second, late season bloom occurred within the central portions of the NMS. The timing of this second bloom relative to those within the salt ponds and the coastal circulation patterns at that time strongly suggest that those cells originated from a regional A. fundyense bloom in the Gulf of Maine, delivered to the central marsh from coastal waters outside the NMS through Nauset Inlet. These results will guide policy decisions about water quality as well as shellfish monitoring and utilization within the NMS and highlight the potential for "surgical" closures of shellfish during PSP events, leaving some areas open for harvesting while others are closed.

We examined effects on physiology and gene expression patterns associated with growth and nutrient starvation in a toxic strain of A. minutum. Bloom-relevant factors, including growth rate, intracellular toxin content, allelochemical activity and nutrient status were investigated in A. minutum cultures grown under different environmental regimes. Allelochemical activity of A. minutum cultures, quantified with a cryptomonad Rhodomonas bioassay, increased with age but was independent of nutrient status. The phenotypic data were integrated and compared with gene expression in cell samples taken at selected points along the growth curve. We observed 489 genes consistently differentially expressed between exponentially growing and growth-limited cultures. The expression pattern of stationary-phase cultures was characterized by conspicuous down-regulation of translation-associated genes, up-regulation of sequences involved in intracellular signalling and some indications of increased activity of selfish genetic elements such as transposons. Treatment-specific patterns included five genes regulated in parallel in all nutrient-limited cultures. The conspicuous decrease in photosynthetic: performance identified in N-starved cultures was paralleled by down-regulation of chloroplast-associated genes. The particular gene expression patterns we identified as specifically linked with exponential growth, cessation of growth or nutrient limitation may be suitable biomarkers for indicating the beginning of growth limitation in field- or mesocosm studies.

The benthic foraminiferal record of the Medieval Warm Period and the recent warming in the Gullmar Fjord, Swedish west coast	MARINE MICROPALEONTOLOGY			English	Article						Medieval Warm Period; Recent warming; Positive NAO; Benthic foraminifera; Nonionella iridea	NORTH-ATLANTIC OSCILLATION; OXYGEN CONCENTRATIONS; CONTINENTAL-SHELF; BATHYMETRIC DISTRIBUTION; TEMPERATURE VARIABILITY; TEMPORAL VARIABILITY; SURFACE TEMPERATURES; DINOFLAGELLATE CYSTS; CLIMATE VARIATIONS; RESERVOIR AGES	A high-resolution study of benthic foraminiferal assemblages was performed on a ca. eight metre long sediment core from Gullmar Fjord on the west coast of Sweden. The results of Pb-210- and AMS C-14-datings show that the record includes the two warmest climatic episodes of the last 1500 years: the Medieval Warm Period (MWP) and the recent warming of the 20th century. Both periods are known to be anomalously warm and associated with positive NAO winter indices. Benthic foraminiferal successions of both periods are compared in order to find faunal similarities and common denominators corresponding to past climate changes. During the MWP, Adercotryma glomerata, Cassidulina laevigata and Nonionella iridea dominated the assemblages. Judging from dominance of species sensitive to hypoxia and the highest faunal diversity for the last ca. 2400 years, the foraminiferal record of the MWP suggests an absence of severe low oxygen events. At the same time, faunas and delta C-13 values both point to high primary productivity and/or increased input of terrestrial organic carbon into the fjord system during the Medieval Warm Period. Comparison of the MWP and recent warming revealed different trends in the faunal record. The thin-shelled foraminifer N. iridea was characteristic of the MWP, but became absent during the second half of the 20th century. The recent Skagerrak-Kattegat fauna was rare or absent during the MWP but established in Gullmar Fjord at the end of the Little Ice Age or in the early 1900s. Also, there are striking differences in the faunal diversity and absolute abundances of foraminifera between both periods. Changes in primary productivity, higher precipitation resulting in intensified land runoff, different oxygen regimes or even changes in the fjord's trophic status are discussed as possible causes of these faunal differences.

NOV; RECENT SEDIMENTS; COASTAL WATERS; LSU RDNA; PHYLOGENETIC ANALYSES; MICRORETICULATE CYST; MOLECULAR PHYLOGENY; POLYKRIKOS-KOFOIDII; ELECTRON-MICROSCOPY; PIGMENT COMPOSITION	Recurrent high-biomass blooms of a gymnodinioid species have been periodically recorded at different sites in the NW Mediterranean Sea (Catalan and Sardinian coast), causing intense discolorations of the water. In this study, several strains of the causative organism were isolated and subsequently studied with respect to the morphology of the vegetative cells and different life cycle stages, pigments profile, and molecular phylogeny. Based on phylogenetic analyses, the strains were placed within the Gymnodinium sensu strict clade. The species possessed a horseshoe-shaped apical groove running anticlockwise around the apex and the major accessory pigment was identified as peridinin. These characteristics place the organism within the Gymnodinium genus, as defined today, although some other characteristics, such as vesicular chambers in the nuclear envelope and a nuclear fibrous connective were not observed. Morphologically, the isolates highly resemble Gyrodinium vorax (Biecheler) but major differences with the latter suggest that they comprise a new species, Gymnodinium litoralis sp. nov. The resting cyst of this species is described herein from field samples of the Catalan and Sardinian coast; pellicle cysts were observed in field samples and also in cultures. This species recurrently produces high biomass blooms (>10(6) cell L-1) in summer along several beaches and coastal lagoons in the NW Mediterranean Sea (L'Estartit, La Muga River mouth, and Corru S'Ittiri). Knowledge about its geographic distribution is limited, since the precise identification of G. litoralis from the field or fixed samples can be difficult. Therefore we expect that molecular studies will reveal a much wider distribution of the species. (C) 2011 Elsevier B.V. All rights reserved.

Short term climate variability during "Roman Classical Period" in the eastern Mediterranean	QUATERNARY SCIENCE REVIEWS			English	Article						Climate; Roman Classical Period; Dinoflagellate cysts; North Atlantic Oscillation	WALLED DINOFLAGELLATE CYSTS; NORTH-ATLANTIC OSCILLATION; RADIOCARBON AGE CALIBRATION; SEA-SURFACE CONDITIONS; WESTERN ADRIATIC SEA; SAHARAN DUST; SELECTIVE PRESERVATION; LAST DEGLACIATION; COSMIC-RAYS; SEDIMENTS	To obtain insight into character and potential forcing of short-term climatic and oceanographic variability in the southern Italian region during the "Roman Classical Period" (60 BC-AD 200), climatic and environmental reconstructions based on a dinoflagelate cyst record from a well dated site in the Gulf of Taranto located at the distal end of the Po-river discharge plume have been established with high temporal resolution. Short-term fluctuations in accumulation rates of the Adriatic Surface Water species Lingulodinium machaerophorum, the freshwater algae Concentricystes and species resistant to aerobic degradation indicate that fluctuations in the trophic state of the upper waters are related to river discharge of northern and eastern Italian rivers which in turn are strongly related to precipitation in Italy. The dinoflagellate cyst association indicates that local sea surface temperatures which in this region are strongly linked to local air temperatures were slightly higher than today. We reconstruct that sea surface temperatures have been relatively high and stable between 60 BC-AD 90 and show a decreasing trend after AD 90. Fluctuations in temperature and river discharge rates have a strong cyclic character with main cyclicities of 7-8 and 11 years. We argue that these cycles are related to variations of the North Atlantic Oscillation climate mode. A strong correlation is observed with global variation in Delta C-14 anomalies suggesting that solar variability might be one of the major forcings of the regional climate. Apart from cyclic climate variability we observed a good correlation between non-cyclic temperature drops and global volcanic activity indicating that the latter forms an additional major forcing factor of the southern Italian climate during the Roman Classical Period.

Spatial distribution of benthic cysts of <i>Alexandrium catenella</i> in surface sediments of Puget Sound, Washington, USA	HARMFUL ALGAE			English	Article						Alexandrium; Dinoflagellate cysts; Harmful algae; Sediments	RESTING CYSTS; DINOFLAGELLATE CYSTS; FUNDYENSE POPULATIONS; GULF; DINOPHYCEAE; ACCUMULATION; CIRCULATION; ENCYSTMENT; DYNAMICS; GEORGIA	Alexandrium catenella cyst distribution and abundance in the surface sediments throughout Puget Sound, Washington, were mapped for the first time in 2005. Cyst density varied from 0 to >12,000 cysts cm(-3) surface sediment, with Quartermaster Harbor having the highest concentration of cysts. A higher resolution 2006 spatial survey of surface sediment cysts in two central Puget Sound bays, Quartermaster Harbor and Dyes Inlet, found cyst distribution to be patchy. Surface sediment properties were also determined for all samples. Given the diverse hydrographic conditions associated with the different basins in Puget Sound, no correlation was found between cyst abundance and grain size or total organic content (TOC) for the large scale Puget Sound wide survey, but cyst abundance was positively correlated with finer grained and higher TOC sediments within bays from the higher resolution survey. Sediment metal concentrations were also determined and cyst abundance was positively correlated only with Cd concentration. These results are consistent with previous studies in other locations.

Here we report the presence of A. ostenfeldii in the Bohai Sea, China, for the first time. The vegetative cells of A. ostenfeldii are characterized by a narrow first apical plate and a large ventral pore located on the anterior right side. Partial large subunit sequence comparison revealed that the Chinese strain differs from the Finnish strains at only three positions, and from A. peruvianum of Spain at five positions. Maximum parsimony analysis revealed that A. ostenfeldii from China and Finland and A. peruvianum from Spain grouped together. They were the nearest sister group to a clade with A. ostenfeldii from New Zealand, Europe, and North America. In culture, growth did not occur at temperatures below 9 degrees C and occurred at salinities between 7 and 27 psu. It took 10-20 days for newly formed cysts to mature at 20 degrees C. Lower temperature delayed germination, but the germination rate exceeded 90% at temperatures from 12 to 24 degrees C. No germination occurred below 9 degrees C after 1 month of incubation. The Chinese strain of A. ostenfeldii produced neither spirolides nor paralytic shellfish poisoning toxins.

J	Calado, AJ				Calado, Antonio Jose			On the identity of the freshwater dinoflagellate <i>Glenodinium edax</i>, with a discussion on the genera <i>Tyrannodinium</i> and <i>Katodinium</i>, and the description of <i>Opisthoaulax</i> gen. nov.	PHYCOLOGIA			English	Article						Dinophyceae; Freshwater; Glenodinium edax; Katodinium; Opisthoaulax gen. nov.; Taxonomy; Tyrannodinium	AMPHIDINIUM DINOPHYCEAE; FLAGELLAR APPARATUS; LAKE TOVEL; ULTRASTRUCTURE; PHYLOGENY	Within the context of the preparation of a flora for the identification of freshwater dinoflagellates, the identity of Glenodinium edax and the affinities of a group of phagotrophic species with a conspicuous eyespot not associated with plastids (eyespot type C) currently classified in Katodinium were re-evaluated. The original description and illustrations of the phagotrophic G. edax suggest affinity with the Pfiesteriaceae. Whereas the tabulation currently associated with G. edax is based on a probable misidentification, the similarity to Tyrannodinium berolinense suggests that the two names can be regarded as synonyms and T. edax comb. nov. is proposed. As presented in modern floras, Katodinium is artificially defined on the basis of the position of the cingulum at or below the posterior third of the cell, and includes widely different forms. The presence of an eyespot of type C in the phagotrophic Katodinium vorticella and related species combines with a general cell morphology reminiscent of Esoptrodinium gemma and the formation of Tovellia-like cysts to mark this group of species as belonging to the Tovelliaceae. The type species of Katodinium, K. nieuportense, is morphologically quite different from these species and does not display tovelliacean characters. None of the known genera of Tovelliaceae matches the characters of K. vorticella and its close relatives. Opisthoaulax gen. nov. is described and new combinations are proposed for K. vorticella and six other species.

This work has focused on germination of dinoflagellate cysts, but diatom resting stages were also observed. We record the longest known survival of dormant dinoflagellate cells. We individually isolated more than 1200 cysts of the three most abundant dinoflagellate taxa: Pentapharsodinium dalei, Lingulodinium polyedrum and Scrippsiella spp. Germination success decreased with core depth, and all successful germinations took place within the first 2 wk of incubation. Pentapharsodinium dalei had the highest germination success rate, with a maximum of up to 80% in 28-yr-old sediment, and could successfully germinate from core sediments dated to 1920 +/- 12. Scrippsiella spp. cysts with cell contents occurred down to c. 90-yr-old sediment and could germinate from down to ca. 40-yr-old sediments, with a maximum germination rate of 50-60% in recent sediments. Cysts of L. polyedrum germinated frequently down to 20 yr and rarely to c. 80 yr, with a maximum of 20-50% germination success in recent sediments. Cyst isolation under cooled conditions rather than at room temperature resulted in a significantly higher germination success in P. dalei, while no effect was observed for L. polyedrum. The time elapsed since slicing of the core affected survival of L. polyedrum cysts negatively, most likely due to the effect of oxygen. The long-term survival potential of benthic resting stages that we report here has important implications, as viable resting stages accumulated in bottom sediments can be transported back to the water column by, for example, bioturbation and human-mediated sediment dredging. Hence, the sediment may to a higher degree than previously considered play a role as seed bank. This is important in a changing climate and might have particularly severe impacts in the case of harmful species.

A total of 47 different types of cysts and a maximum abundance of 1076 cysts g(-1) dry sediment were recorded. Highest cyst abundance was recorded at coastal station Mangalore (801 cysts g dry sediment) and Kochi port (1076 cysts g-1 dry sediment). Lowest cyst abundance was observed at coastal stations from Kochi to Trivandrum. This difference may be attributed to the composition of sediment, since sandy stations had lower abundance and diversity of cysts. Heterotrophic dinoflagellate cysts, mainly Protoperidinium species, were the most diversified, predominating at most of the stations sampled. Cysts of potential Harmtul Algal Bloom (HAB) species capable of forming blooms were also detected in the sediment. Effect of the environmental settings of the study area such as upwelling, South West monsoon and anthropogenic pressures on the dynamics of these HAB species in Indian waters needs to be elucidated.

THE TOXIC DINOFLAGELLATE <i>GYMNODINIUM CATENATUM</i> (DINOPHYCEAE) REQUIRES MARINE BACTERIA FOR GROWTH	JOURNAL OF PHYCOLOGY			English	Article						antibiotic; axenic; bacteria; culture; dinoflagellate; growth; Gymnodinium catenatum; interaction; stimulation	PARALYTIC SHELLFISH TOXIN; ALEXANDRIUM-TAMARENSE; IRON UPTAKE; RED-TIDE; PHYTOPLANKTON; CULTURES; ALGAE; PURIFICATION; DIVERSITY; SAXITOXIN	Interactions with the bacterial community are increasingly considered to have a significant influence on marine phytoplankton populations. Here we used a simplified dinoflagellate-bacterium experimental culture model to conclusively demonstrate that the toxic dinoflagellate Gymnodinium catenatum H. W. Graham requires growth-stimulatory marine bacteria for postgermination survival and growth, from the point of resting cyst germination through to vegetative growth at bloom concentrations (10(3) cells mL(-1)). Cysts of G. catenatum were germinated and grown in unibacterial coculture with antibiotic-resistant or antibiotic-sensitive Marinobacter sp. DG879 or Brachybacterium sp., and with mixtures of these two bacteria. Addition of antibiotics to cultures grown with antibiotic-sensitive strains of bacteria resulted in death of the dinoflagellate culture, whereas cultures grown with antibiotic-resistant bacteria survived antibiotic addition and continued to grow beyond the 21 d experiment. Removal of either bacterial type from mixed-bacterial dinoflagellate cultures (using an antibiotic) resulted in cessation of dinoflagellate growth until bacterial concentration recovered to preaddition concentrations, suggesting that the bacterial growth factors are used for dinoflagellate growth or are labile. Examination of published reports of axenic dinoflagellate culture indicate that a requirement for bacteria is not universal among dinoflagellates, but rather that species may vary in their relative reliance on, and relationship with, the bacterial community. The experimental model approach described here solves a number of inherent and logical problems plaguing studies of algal-bacterium interactions and provides a flexible and tractable tool that can be extended to examine bacterial interactions with other phytoplankton species.

Many Syndiniales obligatorily kill their hosts to accomplish their life cycle. This is the case for Amoebophrya spp. infecting dinoflagellates. However, several dinoflagellate species known to be infected by these parasites produce diploid resting cysts as part of their life history. These resting cysts may survive several seasons in the sediment before germinating. How these parasites survive during the dormancy of their host remained an open question. We successfully established infections by Amoebophrya sp. in the red tide dinoflagellate Scrippsiella trochoidea. This host strain was homothallic and able to continuously produce typical calcified cysts covered by calcareous spines. Presence of the parasite significantly speeded up the host cyst production, and cysts produced were the only cells to resist infections. However, some of them were clearly infected, probably earlier in their formation. After 10 months, cysts produced in presence of the parasite were able to germinate and new infective cycles of the parasite were rapidly observed. Thus, a very novel relationship for protists is demonstrated, one in which parasite and host simultaneously enter dormancy, emerging months later to propagate both species. (C) 2011 Elsevier GmbH.

The strain studied, ACT03, was grown in an artificial seawater medium. The influence of temperature and that of salinity were analysed using 48 different combinations of 6 salinities (10-40 psu) and 8 temperatures (9-30 degrees C) under saturating irradiance (100 mu mol photons m(-2) s(-1)). ACT03 appeared to be an euryhaline strain that can survive at salinities as low as 10 psu and can grow at salinities up to 40 psu. This strain can grow between 15 and 30 degrees C. The highest growth rates (>0.4 day(-1)) were observed between 35 and 40 psu and 15 and 27 degrees C. The influence of irradiance on growth and cell pigment content was tested between 10 and 260 mu mol photons m(-2) s(-1) at 20 degrees C and 38 psu. The results revealed both a low compensation irradiance and that light saturation was reached at 90 mu mol photons m(-2) s(-1). Temperature had the greatest influence on growth. The ecophysiological characteristics reported here are consistent with the environmental conditions encountered in the Thau lagoon. A. catenella exhibited important adaptive capacities over the large range of tested physical factors. This flexibility helps us to explain its ability to bloom seasonally on the Mediterranean coast, where the physico-chemical environmental conditions are characterized by high seasonal variations.

Comparison with typical Peridinium, Peridiniopsis, Palatinus and Scrippsiella species revealed significant structural differences, congruent with phylogenetic hypotheses derived from partial LSU rDNA sequences. Chimonodinium gen. nov. is described as a new genus of peridinioids, characterized by the Kofoidian plate formula Po, cp, x, 4', 3a, 7 '', 6c, 5 s, 5''', 2 '''', the absence of pyrenoids, the presence of a microtubular basket with four or five overlapping rows of microtubules associated with a small peduncle, a pusular system with well-defined pusular tubes connected to the flagellar canals, and the production of non-calcareous cysts. Serial section examination of Scrippsiella trochoidea, here taken to represent typical Scrippsiella characters, revealed no peduncle and no associated microtubular strands. The molecular phylogeny placed C. lomnickii comb. nov. as a sister group to a clade composed of Thoracosphaera and the pfiesteriaceans. Whereas the lack of information on fine structure of the swimming stage of Thoracosphaera leaves its affinities unexplained, C. lomnickii shares with the pfiesteriaceans the presence of a microtubular basket and the unusual connection between two plates on the left side of the sulcus, involving extra-cytoplasmic fibres.

Ships visiting several ports in the provinces of Quebec, New Brunswick and Nova Scotia were sampled during three summers (2007, 2008, 2009). These ships included general cargo, bulk carriers and oil tankers, and they represented two major categories: ships undergoing continental and trans-oceanic voyages. Our results show that potentially viable dinoflagellate cysts are present in ballast sediments of all the categories of ships arriving to the East coast of Canada. The concentrations of all types of dinoflagellate cysts are higher in continental ships without ballast water exchange (BWE) than in ships with BWE, including trans-oceanic ships, which presented lower risk of introduction of non-indigenous species (NIS) of dinoflagellates. We identified 14 non-indigenous dinoflagellate cyst species not yet reported from Canadian coasts, including 4 potentially harmful/toxic species, representing a possibility of new introductions. These introductions of toxic NIS could represent a problem for marine Canadian ecosystems, with potentially disastrous effects on fish communities, aquaculture and human health. This potential risk may be facilitated with climate change.

A dinoflagellate producer of pinnatoxin G, isolated from sub-tropical Japanese waters	HARMFUL ALGAE			English	Article						Pinnatoxin G; Dinoflagellate; Peridiniales; Japan; Australasia	SHELLFISH POISON; DINOPHYCEAE	A thecate dinoflagellate (Peridiniales, Dinophyceae) was cultured from individual non-calcareous cysts, isolated from surface sediment samples collected in Okinawa, Japan. Two isolates (CAWD188 and CAWD190) from two different sampling sites, each cultured from an individual cyst, produced ca. 11.9 and 15 pg cell(-1) pinnatoxin G, respectively, as determined by liquid chromatography-mass spectrometric (LC-MS). No other pinnatoxins were detected. The motile cells and cysts appeared morphologically identical to those of pinnatoxins E and F producers isolated from New Zealand waters and pinnatoxins E, F, and G producers isolated from Australian waters. Motile and cysts cells measured an average of 25 mu m long x 21.3 mu m wide and 29 mu m long x 25.5 mu m wide, respectively. Analysis of the large subunit ribosomal DNA sequence data showed two well supported strains with slight differences between the Japanese and the Australasian isolates. (C) 2011 Elsevier B.V.

Logarithmically growing Gambierdiscus inocula were admixed (1:6, vol:vol) with ballast water, maintained in the dark at 22.6 degrees C, 24.6 degrees C, 26.8 degrees C and 29.0 degrees C and assessed for numerical abundance over six days. Calculated growth rates from the biomass time series showed no indication that ballast water negatively impacted Gambierdiscus viability; accompanying microscopic inspections supported this conclusion. Filtration of large volumes of collected ballast water failed to show the presence of any Gambierdiscus cells contained therein. Recovery and microscopic examination of the experimental inocula after 10 weeks in the dark, failed to show cyst development at any temperature regime. This examination of ballast water showed no evidence of cytotoxicity to Gambierdiscus spp. (C) 2011 Elsevier B.V. All rights reserved.	[Bienfang, P. K.; DeFelice, S.

First, batch cultures were grown in 450 mL flasks without aeration and under varying conditions of temperature (16 and 22 degrees C) and culture medium (L1, f/2 and L1 with addition of soil extract). Second, cultures were grown at 16 degrees C in 8 L aerated flat-bottomed vessels using L1 with soil extract as culture medium. Finally, continuous cultures in a photobioreactor were conducted at 18 degrees C in L1 with soil extract; pH was maintained at 8.5 and continuous stirring was applied. This study showed that A. ostenfeldii growth was significantly affected by temperature. At the end of the exponential phase, maximum cell concentration and cell diameter were significantly higher at 16 degrees C than at 22 C. In batch culture, maximum spirolide quota per cell (approx. 5 pg SPX 13-desMeC eq cell(-1)) was detected during lag phase for all conditions used. Spirolide quota per cell was negatively and significantly correlated to cell concentration according to the following equation: y = 4013.9x(-0.858). Temperature and culture medium affected the spirolide profile which was characterized by the dominance of 13,19-didesMeC (29-46%), followed by SPX-D (21-28%), 13-desMeC (21-23%), and 13-desMeD (17-21%). Stable growth of A. ostenfeldii was maintained in a photobioreactor over two months, with maximum cell concentration of 7 x 10(4) cells mL(-1). As in batch culture, maximum spirolide cell quota was found in lag phase and then decreased significantly throughout the exponential phase. Spirolide cell quota was negatively and significantly correlated to cell concentration according to the equation: y = 12,858x(-0.8986). In photobioreactor, spirolide profile was characterized by higher proportion of 13,19-didesMeC (60-87%) and lower proportions of SPX-D (3-12%) and 13-desMeD (1.6-10%) as compared to batch culture.

Thus far, eight different diatom viruses infecting the genera Rhizosolenia and Chaetoceros have been isolated and characterized to different extents. We report the isolation of a novel diatom virus (ClorDNAV), which causes the lysis of the bloom-forming species Chaetoceros lorenzianus, and show its physiological, morphological, and genomic characteristics. The free virion was estimated to be similar to 34 nm in diameter. The arrangement of virus particles appearing in cross-section was basically a random aggregation in the nucleus. Occasionally, distinctive formations such as a ring-like array composed of 9 or 10 spherical virions or a centipede-like array composed of rod-shaped particles were also observed. The latent period and the burst size were estimated to be <48 h and 2.2 x 10(4) infectious units per host cell, respectively. ClorDNAV harbors a covalently closed circular single-stranded DNA (ssDNA) genome (5,813 nucleotides [nt]) that includes a partially double-stranded DNA region (979 nt). At least three major open reading frames were identified; one showed a high similarity to putative replicase-related proteins of the other ssDNA diatom viruses, Chaetoceros salsugineum DNA virus (previously reported as CsNIV) and Chaetoceros tenuissimus DNA virus. ClorDNAV is the third member of the closed circular ssDNA diatom virus group, the genus Bacilladnavirus.

Diversity and Dynamics of a Widespread Bloom of the Toxic Dinoflagellate <i>Alexandrium fundyense</i>	PLOS ONE			English	Article							DIATOM DITYLUM-BRIGHTWELLII; POPULATION GENETIC-STRUCTURE; MICROSATELLITE MARKERS; GONYAULAX-TAMARENSIS; CYST FORMATION; SPRING BLOOM; BACILLARIOPHYCEAE; SOFTWARE; DIFFERENTIATION; DINOPHYCEAE	Historically, cosmopolitan phytoplankton species were presumed to represent largely unstructured populations. However, the recent development of molecular tools to examine genetic diversity have revealed differences in phytoplankton taxa across geographic scales and provided insight into the physiology and ecology of blooms. Here we describe the genetic analysis of an extensive bloom of the toxic dinoflagellate Alexandrium fundyense that occurred in the Gulf of Maine in 2005. This bloom was notable for its intensity and duration, covering hundreds of kilometers and persisting for almost two months. Genotypic analyses based on microsatellite marker data indicate that the open waters of the northeastern U.S. harbor a single regional population of A. fundyense comprising two genetically distinct sub-populations. These subpopulations were characteristic of early-and late-bloom samples and were derived from the northern and southern areas of the bloom, respectively. The temporal changes observed during this study provide clear evidence of succession during a continuous bloom and show that selection can act on the timescale of weeks to significantly alter the representation of genotypes within a population. The effects of selection on population composition and turnover would be magnified if sexual reproduction were likewise influenced by environmental conditions. We hypothesize that the combined effects of differential growth and reproduction rates serves to reduce gene flow between the sub-populations, reinforcing population structure while maintaining the diversity of the overall regional population.

Dinoflagellate cyst assemblages observed in the study area included many species commonly reported from other temperate regions. Among them, Polykrikos cysts were dominant, together with Brigantedinium spp. and Spiniferites spp. Based on cluster analysis, dinoflagellate cyst assemblages were divided into two main groups; group I, located in Yeoja Bay and group II, located in Gamak Bay and the offshore area of Yeoja Bay. Principal component analysis identified differences in salinity levels as the main environmental factors affecting the distributional characteristics of dinoflagellate cyst assemblages in the study area. Gamak Bay is a typical eutrophied area as result of extensive human activities around the bay, and heterotrophic cysts, including Polykrikos cysts, are remarkably abundant and likely to be a useful indicator for eutrophication in Gamak Bay.

Coupling SYBR-Green I and SYTOX-Green staining, FCM analysis and sorting, and microscopic observations permitted identification and characterization of five cellular states/forms of A. minutum: (1) vegetative cells, (2) pellicle cysts, (3) degraded cells, (4) empty theca, and (5) dead cells. Storage on ice resulted in the transformation of a portion of vegetative cells into dead cells, pellicle cysts, and "degraded" cells: however, centrifugation resulted mostly in pellicle cysts and a few degraded cells. After these thermal and mechanical treatments, control and stressed cultures were monitored for 14 days. Stressed A. minutum cultures appeared to grow at the same rates as control cultures during the first seven days. During the last week of monitoring, however, cell densities of stressed cultures reached their stationary phase earlier than control cultures, suggesting incomplete recovery. Additional experiment assessing kinetics of excystment indicated that it can occur less than 9 h following mechanical stress (centrifugation) and that 75% of the culture can excyst within 24 h. Upon 30 min of exposure to chemical stressors (saponine and H2O2), only vegetative cells, pellicle cysts, and dead cells were detected. For both chemicals, encystment was dose-dependent. Counts of pellicle cysts increased with increasing saponine or H2O2 concentration. Pellicle cysts were the most-predominant cell type at chemical treatments above 0.05 g L-1 saponine and above 0.015% H2O2. Occurrence of dead cells appeared to follow an all-or-none response as dead-cell percentage increased from 3% at 0.015% H2O2 to 81% at 0.03% H2O2 without pellicle cyst formation. Overall, encystment-excystment of A. minutum upon changes of environmental conditions can occur very rapidly but can be monitored using FCM and SYBR-Green I staining. (C) 2011 Elsevier B.V.

A preliminary study of the formation of a third category of cysts by a toxigenic dinoflagellate, <i>Alexandrium fundyense</i> in response to elevated concentrations of ammonium chloride	HARMFUL ALGAE			English	Article						Alexandrium fundyense; Cysts; Iron; Toxins	GONYAULAX-TAMARENSIS; LIFE-CYCLE; RED TIDE; MARINE MICROALGAE; RESTING CYSTS; IRON; DINOPHYCEAE; NITROGEN; ENCYSTMENT; DIATOM	Exposure of exponentially growing cells of a toxigenic dinoflagellate strain, Alexandrium fundyense, to ammonium chloride concentrations comparable to levels of ammonia observed in Bay of Fundy waters induced formation in a few days of large numbers of double-walled, circular cysts (termed forced cysts). The A. fundyense forced cysts were distinctly different from the asexual pellicle cysts, and the sexual resting cysts (hypnocysts) described by Anderson and Wall (1978). The circular shape of these forced cysts and their relatively rapid formation suggest that they were not products of fusion while their resistance to adverse conditions and, when returned to optimal conditions, their subsequent rapid germination to form viable cultures within 14 days, point to an important long-term survival role in response to rapidly changing nutritional and environmental circumstances as well as in the waxing and waning of local toxic dinoflagellate blooms. The relative ease of producing the forced cysts and their fairly rapid germination suggest that these cysts could be suitable vehicles for investigations of the physiology and biochemistry of encystment and excystment in the species producing them. Chemical analyses of forced cysts harvested from cultures of this A. fundyense strain showed large variabilities in selected storage products: iron ranged from 0.03 pg to 17.40 pg Fe/cyst corresponding to 0.04-61.25% of the cyst dry weight; nitrogen levels ranged from 109 pg to 3183 pg/cyst and phosphorus ranged from 0.55 pg to 5.70 pg/cyst. Total paralytic shellfish poisons for these A. fundyense cysts consisted of the same toxins apparent in the vegetative cells, i.e. C1C2 toxins, GTX 2/3, saxitoxin and neosaxitoxin, and ranged from 4.4 fmol to 333 fmol/fg cyst dry wt.

Dinoflagellate cyst assemblages reveal relatively stable pelagic productivity over the last two centuries. Similarly, geochemical (organic C, C-org : N) and isotopic (delta C-13(org), delta N-15) data reveal that organic matter fluxes to the seafloor have been relatively constant over the same period. In contrast, significant changes are recorded in the benthic foraminifer assemblages. A sediment surface peak in the abundance of Cassidulina laevigata and Brizalina subaenariensis is consistent with the recent record of oxygen depletion in the bottom water. A decrease in the relative abundance of Nonionellina labradorica, concomitant with a relatively higher occurrence of Oridorsalis umbonatus in the upper part of the core, reflects a significant warming of the bottom water. Changes in bottom-water properties are further constrained by a negative trend of the delta O-18 in Bulimina exilis carbonate shells over the last century, corresponding to a warming of about 2 degrees C. These results strongly suggest that the recent oxygen depletion in the bottom waters of the Gulf of St. Lawrence is due to changes in water masses that have led to increased bottom-water temperatures and, to some extent, a resultant increase in organic matter respiration rates.

Analysis of approximately 3500 spring bloom samples from the Baltic Sea monitoring programs revealed (i) that within the major basins the proportion of dinoflagellates varied from 0.1 (Kattegat) to.0.8 (central Baltic Proper), and (ii) substantial shifts (e. g. from 0.2 to 0.6 in the Gulf of Finland) in the dinoflagellate proportion over four decades. During a recent decade (1995-2004) the proportion of dinoflagellates increased relative to diatoms mostly in the northernmost basins (Gulf of Bothnia, from 0.1 to 0.4) and in the Gulf of Finland, (0.4 to 0.6) which are typically ice-covered areas. We hypothesize that in coastal areas a specific sequence of seasonal events, involving wintertime mixing and resuspension of benthic cysts, followed by proliferation in stratified thin layers under melting ice, favors successful seeding and accumulation of dense dinoflagellate populations over diatoms. This head-start of dinoflagellates by the onset of the spring bloom is decisive for successful competition with the faster growing diatoms. Massive cyst formation and spreading of cyst beds fuel the expanding and ever larger dinoflagellate blooms in the relatively shallow coastal waters. Shifts in the dominant spring bloom algal groups can have significant effects on major elemental fluxes and functioning of the Baltic Sea ecosystem, but also in the vast shelves and estuaries at high latitudes, where ice-associated cold-water dinoflagellates successfully compete with diatoms.

Our aim in this study is to compare the dinocyst signature between 50 and 25 ka BP with existing datasets of foraminiferal and geochemical proxies related to hydrological parameters. Quantitative reconstructions of sea-surface temperatures (SSTs) and salinities (SSS) based on dinocysts are performed for the first time in this area. The results are compared to SSTs derived from planktonic foraminifera and alkenone measurements, and to SSS calculated from planktonic delta O-18 and foraminiferal SST. Significant oscillations related to Dansgaard-Oeschger cycles are recorded in both cores. Dinocyst-derived hydrological parameters exhibit synchronous fluctuations and similar values to those derived from the other methods, in particular when considering quantitative reconstructions for February based on foraminifera and dinocysts. Our study shows that the influence of subpolar waters was felt during each Greenland Stadial (GS) off Portugal, and that the amplification of the Heinrich Stadial cooling in the Alboran Sea was related to the penetration of subpolar waters through the Strait of Gibraltar. During Greenland Interstadials (GI), we provide evidence for the occurrence of warm and nutrient-rich sea-surface waters in the Alboran Sea, probably due to gyre-induced upwelling. Finally, the difference between August and February dinocyst SST estimates suggests higher seasonal contrasts during GS compared to Cl at the two core sites. Additionally, precession appears to have an imprint on dinocyst-derived long-term seasonality record. However, this observation needs to be confirmed by longer records. (c) 2011 Elsevier B.V.

At least thirty-six dinoflagellate cyst types were identified, with the assemblages mainly dominated by Lingulodinium machaerophorum, Polykrikos kofoidii, Operculodinium centrocarpum, Gymnodinium cf. nolleri and Quinquecuspis concreta. Total cyst concentrations ranged from 41 to 3292 cystsg(-1) dry weight sediment. The majority of the cysts occurred in the inner and middle parts of the bay, where higher cyst concentrations were observed. According to the One Way Anova test, the difference between stations was significant statistically (p < 0.05). Two of the dinoflagellate cyst species have not been recorded previously as cysts or motile stages in Aegean marine waters; Gymnodinium cf. nolleri and Oblea acanthocysta. Alexandrium minutum and Alexandrium offine type cyst were observed at almost all stations although the cyst type of the Alexandrium catenella/tamarense complex was only found in the outer bay. These findings indicate potential seedbeds for initiation of future blooms and outbreaks of potentially toxic species in Izmir Bay. (c) 2011 Elsevier B.V. All rights reserved.

The effects of prolonged darkness on temperate and tropical marine phytoplankton, and their implications for ballast water risk management	MARINE POLLUTION BULLETIN			English	Article						Phytoplankton; Dark incubation; Ballast water; Risk assessment	MICROCYSTIS-AERUGINOSA; DINOFLAGELLATE CYSTS; SURVIVAL STRATEGIES; MEDITERRANEAN SEA; MIDOCEAN EXCHANGE; DIATOM MORTALITY; DOMOIC ACID; BALTIC SEA; TRANSPORT; BLOOM	Phytoplankton assemblages from tropical (Goa) and temperate (UK) locations were exposed to a 28 day dark period, followed by a period of re-exposure to light. During this time phytoplankton survival and changes in nutrient concentrations were mapped. The tropical plankton water samples showed high nutrient levels after the dark period which were utilised by cells during the re-exposure period. UK experiments looked at the effect of three different water types on population recovery after the 28 day dark period, and differences due to seasonal effects. The population growth observed during the re-exposure period in the tropical population was comparable to that of the temperate population. Water type affected recovery and of the three tested media fresh seawater promoted the highest levels of growth. Seasonality had a significant influence on species survival. Understanding the effects of all these factors can aid the development of effective risk assessments in ballast water management. (C) 2011 Elsevier Ltd. All rights reserved.	[Carney, K.

Temporal variation of caspase 3-like protein activity in cultures of the harmful dinoflagellates <i>Karenia brevis</i> and <i>Karenia mikimotoi</i>	JOURNAL OF PLANKTON RESEARCH			English	Article						caspase 3-like protein activity; cell death; harmful dinoflagellate; Karenia spp.	PROGRAMMED CELL-DEATH; RED TIDE DINOFLAGELLATE; HEAT-STRESS; PHYTOPLANKTON; APOPTOSIS; METACASPASES; INDUCTION; GROWTH; PHOTOSYNTHESIS; CYANOBACTERIUM	To better understand the role of caspase-like proteins in the cellular activities of harmful dinoflagellates, cultures of Karenia brevis and Karenia mikimotoi were monitored over a 56-day period. The cellular abundance, maximum photochemical efficiency of photosystem II (F-v/F-m), percentage of dead cells (revealed by SYTOX-labelling of nuclei of cells with a compromised membrane) and the variation in caspase 3-like protein activity were monitored every 7 days. During the cultures' late decline phase, DNA degradation was also confirmed in Karenia cells using a terminal deoxynucletidyl transferase-mediated dUTP nick end labelling assay. Karenia brevis reached its maximal cellular abundance after 3 weeks then declined to its lowest value on Day 56. In cells of K. brevis the caspase 3-like activity likely served some housekeeping functions as demonstrated by the constitutive level of activity observed throughout the whole experiment (similar to 3000-6664 RFU/h/mg protein). The increase in activity which occurred on Days 21 and 28 (similar to 38 000 RFU/h/mg protein on Day 28) coincided with the appearance cyst-like structures in the cultures and suggests a role in the encystment progression of K. brevis. For K. mikimotoi, the highest cellular abundance was reached on Day 42 after which it declined to reach its lowest value, along with the highest percentage of dead cells, on Day 56. The caspase 3-like protein activity (<1300 RFU/h/mg protein) was elevated at the beginning of the experiment (on Days 0, 7 and 14) and just before the decline in cellular abundance (on Days 35 and 42) and likely played some housekeeping functions as well as a role in the death of the cells. This study demonstrates the involvement of caspase 3-like protein activity in a variety of processes in cells of the harmful algae K. brevis and K. mikimotoi.

Analyses were performed on three sediment cores from Daya Bay, South China Sea covering the past hundred years. Changes in cyst assemblages as well as geochemical parameters including biogenic silica (BSi), organic carbon (OC) and total nitrogen (TN) reflected environmental change in the area. The clear increase in overall cyst concentration and the prominence of Scrippsiella cysts suggested an increase in cultural eutrophication which began in the 1970s and become evident since 1985. Large fluctuation in cyst assemblages and BSi in the upper 22 cm signaled the influence of construction and operation of nuclear power stations on phytoplankton community and environments, with an increase in the early stage of construction, a rapid decline in the late stage of construction and early operation, and then a sharp increase thereafter. High Alexandrium cyst abundance in shallowest sediments was consistent with high PSP levels and PSP events in the area, and the persistent toxicity suggests recurrent seeding from the rich cyst bed in these surface sediments.

Phytoplankton samples were analyzed in detail by light and scanning electron microscopy revealing the presence of resting cyst and motile cells of P. reticulatum. Oceanographic and phytoplankton data suggest that the bloom was initiated offshore by motile cells and germinated cysts during an upwelling pulse. These cells were advected into the bay when upwelling relaxed and grew without any relevant competitor. Phytoplankton net samples were found to contain yessotoxin as the only toxin in an estimated proportion of 0.2 and 0.4 pg cell(-1), thus confirming that P. reticulatum is a source of yessotoxin in northern Chilean waters and consequently that it poses a risk for human health and mollusk exploitation in the area.

Recent environmental DNA surveys based on clone libraries of rRNA genes confirm this observation and reveal a high diversity of eukaryotes present in deep-sea sediment samples. However, environmental clone-library surveys yield only a modest number of sequences with which to evaluate the diversity of abyssal eukaryotes. Methodology/Principal Findings: Here, we examined the richness of eukaryotic DNA in deep Arctic and Southern Ocean samples using massively parallel sequencing of the 18S ribosomal RNA (rRNA) V9 hypervariable region. In very small volumes of sediments, ranging from 0.35 to 0.7 g, we recovered up to 7,499 unique sequences per sample. By clustering sequences having up to 3 differences, we observed from 942 to 1756 Operational Taxonomic Units (OTUs) per sample. Taxonomic analyses of these OTUs showed that DNA of all major groups of eukaryotes is represented at the deep-sea floor. The dinoflagellates, cercozoans, ciliates, and euglenozoans predominate, contributing to 17%, 16%, 10%, and 8% of all assigned OTUs, respectively. Interestingly, many sequences represent photosynthetic taxa or are similar to those reported from the environmental surveys of surface waters. Moreover, each sample contained from 31 to 71 different metazoan OTUs despite the small sample volume collected. This indicates that a significant faction of the eukaryotic DNA sequences likely do not belong to living organisms, but represent either free, extracellular DNA or remains and resting stages of planktonic species. Conclusions/Significance: In view of our study, the deep-sea floor appears as a global DNA repository, which preserves genetic information about organisms living in the sediment, as well as in the water column above it. This information can be used for future monitoring of past and present environmental changes.

Their morphological taxonomy has been established over the last century. Here, we examined relationships within the genus Peridinium, including Peridinium bipes F. Stein sensu lato, based on a molecular phylogeny derived from nuclear rDNA sequences. Extensive rDNA analyses of nine selected Peridinium species showed that intraspecies genetic variation was considerably low, but interspecies genetic divergence was high (> 1.5% dissimilarity in the nearly complete 18S sequence; > 4.4% in the 28S rDNA D1/D2). The 18S and 28S rDNA Bayesian tree topologies showed that Peridinium species grouped according to their taxonomic positions and certain morphological characters (e.g., epithecal plate formula). Of these groups, the quinquecorne group (plate formula of 3', 2a, 7 ') diverged first, followed by the umbonatum group (4', 2a, 7 ') and polonicum group (4', 1a, 7 '). Peridinium species with a plate formula of 4', 3a, 7 ' diverged last. Thus, 18S and 28S rDNA D1/D2 sequences are informative about relationships among Peridinium species. Statistical analyses revealed that the 28S rDNA D1/D2 region had a significantly higher genetic divergence than the 18S rDNA region, suggesting that the former as DNA markers may be more suitable for sequence-based delimitation of Peridinium. The rDNA sequences had sufficient discriminative power to separate P. bipes f. occultaum (Er. Lindem.) M. Lefevre and P. bipes f. globosum Er. Lindem. into two distinct species, even though these taxa are morphologically only marginally discriminated by spines on antapical plates and the shape of red bodies during the generation of cysts. Our results suggest that 28S rDNA can be used for all Peridinium species to make species-level taxonomic distinctions, allowing improved taxonomic classification of Peridinium.

We then provide an overview of what is known regarding aspects of O. marina growth, indicate where information is needed and suggest ways in which this species can and cannot be used as a general model, in this respect. Little is known about the O. marina life cycle; it is even unknown if cells are haploid, diploid or polyploid, although there is one report that sex occurs by homothallic isogamy. There is considerable information on the cell cycle, which we briefly review and provide a guide to the literature for details. We briefly discuss and provide guidance to information on: (i) population cell size distributions; (ii) cannibalism; (iii) our first report of "mini-cells" in cultures (similar to 8 mu m) and their possible role in the life cycle; (iv) cysts, and their possible role in the life and cell cycles; (v) biotic influences on growth, such as food type and abundance, assimilation efficiency, prey stiochiometry, strain differences, population growth and starvation and nutritional shifts; (vi) abiotic factors that affect growth, such as temperature, salinity, pH, light and turbulence. We then reflect on the consequences of interactions between the above factors and review data on population growth of O. marina in the field and laboratory. Finally, we evaluate the use of O. marina as a model organism to examine cell and life cycles and ecological processes. Throughout the paper, we suggest areas that need evaluation.

Electroporation and lysis of marine microalga <i>Karenia brevis</i> for RNA extraction and amplification	JOURNAL OF THE ROYAL SOCIETY INTERFACE			English	Article						electroporation; dielectrophoresis; Karenia brevis; RNA extraction; RNA amplification; dinoflagellate cysts	CELL-LYSIS; SAMPLE PREPARATION; DIELECTROPHORESIS; DEVICE; CHIP; FLOW; DNA; QUANTIFICATION; PURIFICATION; MANIPULATION	We describe here a simple device for dielectrophoretic concentration of marine microalga Karenia brevis nonmotile cells, followed by electric field-mediated lysis for RNA extraction. The lysate was purified using magnetic beads and pure RNA extracted. RNA quality was assessed off-chip by nucleic acid sequence-based amplification and the optimum conditions for lysis were determined. This procedure will form part of an integrated microfluidic system that is being developed with sub-systems for performing cell concentration and lysis, RNA extraction/purification and real-time quantitative RNA detection. The integrated system and its components could be used for a large range of applications including in situ harmful algal bloom detection, transcriptomics and point-of-care diagnostics.	[Bahi, M.

Blooms are recurrent and usually occur each year in spring and/or autumn. Taxonomic diversity of resting cysts and vegetative cells has been studied through morphological examination and molecular typing of 558 clonal strains sampled in 2004 and 2007. Sequencing the nuclear rRNA fragment, including ITS1, the 5.8S rRNA gene, ITS2, and the D1/D2 28S rRNA genes, enabled two species to be determined, A. catenella and A. tamarense, which are difficult to distinguish morphologically (cryptic species). In order to carry out extensive and accurate molecular determinations, an original semi-multiplex PCR method, using new ribotype-specific primers targeting the 18S-28S rRNA ITS region, has been developed. The relative abundance of each species was then established in seawater in 2007 and in the sediment collected in 2004. The co-occurrence of A. catenella (Group IV), which is known as the main species responsible for toxic PSP events since 1998 and of A. tamarense (Group III) (non-toxic) that was not formally recognized by microscopic observation since 1995, was examined for several months.

In the present study we analyse 12 sediment samples from the China Sea to establish the existence of calcareous dinoflagellates in this area. A total of 11 calcareous dinoflagellate species were recorded, among them, three genera (Calciodinellum, Leonella, Posoniella) and seven species (Calciodinellum albatrosianum, C. levantinum, C. operosum, Leonella granifera, Posoniella tricarinelloides, Scrippsiella irregularis, and S. regalis) were reported from the China Sea for the first time. Cysts of S. irregularis and S. precaria are identical, with a mesoepicystal archeopyle, representing the loss of 2-4' and 1-3a paraplates; however, their thecal plates vary slightly and differ from each other in 78 positions of the internal transcribed spacer sequence. Scrippsiella trochoidea is dominant in coastal areas, whereas Calciodinellum albatrosianum is the most abundant offshore. Scrippsiella irregularis is distributed widely along the coast of China, whereas S. precaria is recorded only in northern China. Leonella granifera is the second most abundant species offshore, comprising 15-40% of the cyst assemblage.

Low P/N ratios seem to induce gamete expression because the percentage of planozygotes recorded in the absence of added phosphate (-P) was significantly higher than that obtained in the absence of added nitrogen (-N), or when the concentrations of both nitrogen and phosphate were 20 times lower (N/20 + P/20). 2. Salinity (S) and temperature (T) strongly affected both planozygote and cyst formation, as sexuality in the population increased significantly as salinity decreased and temperatures increased. S, T combinations that resulted in no significant cyst formation were, however, favorable for vegetative growth, ruling out the possibility of negative effects on cell physiology. 3. The initial cell density is thought to be important for sexual cyst formation by determining the chances of gamete contact. However, the inoculum concentrations tested did not explain either planozygote formation or the appearance of resting cysts.

Occurrence and germination of dinoflagellate cysts in surface sediments from the Red Sea off the coasts of Saudi Arabia	OCEANOLOGIA			English	Article						Cyst; Dinoflagellates; Red Sea; Saudi Arabia; Toxic species	ALEXANDRIUM-CATENELLA DINOPHYCEAE; RECENT MARINE-SEDIMENTS; SHIPS BALLAST WATER; RESTING CYSTS; ONAGAWA BAY; WEST-COAST; BLOOM; SCRIPPSIELLA; DYNAMICS; ASSEMBLAGES	The distribution and abundance of dinoflagellate cyst assemblages were investigated in surface sediments from south-western Red sea coasts of Saudi Arabia at six sites during March 2010. A total of 19 taxa of dinoflagellate cysts were identified from all sites. The sampling sites showed a similar cyst assemblage, but they differed in total cyst abundance (3 to 4083 cysts g(-1) dry weight). Cyst abundance was strongly correlated with sediment characteristics, the highest numbers being recorded in sediments with large contents of organic carbon, silt and clay. Cyst assemblages were dominated by cysts of potentially toxic species, including Cochlodinium polykrikos, Prorocentrum minimum, Dinophysis acuminata, Alexandrium catenella and Scrippsiella trochoidea. Most cysts germinated successfully at different rates at 15 and 25 degrees C. This study suggests that surface sediments from all Saudi Red Sea coasts should be monitored for the presence of dinoffagellate cysts to give ample warning of the presence and abundance of toxic species in a. given area.

J	Villac, MC; Kaczmarska, I				Villac, Maria Celia; Kaczmarska, Irena			Estimating propagule pressure and viability of diatoms detected in ballast tank sediments of ships arriving at Canadian ports	MARINE ECOLOGY PROGRESS SERIES			English	Article						Diatoms; Biological invasion; Ballast sediment; Propagule pressure; Phytoplankton viability	DINOFLAGELLATE CYSTS; BIOLOGICAL INVASIONS; MIDOCEAN EXCHANGE; GREAT-LAKES; CELL-DEATH; WATER; MARINE; PHYTOPLANKTON; TRANSPORT; COAST	This research uses the concept of propagule pressure (number of individuals introduced and number of introduction attempts) to investigate human-mediated bioinvasion patterns. We quantified diatoms in the sediments of ballast tanks of commercial ships arriving on both Canadian coasts during 2007 to 2009. Diatom cell concentrations varied from non-detected to 10(5) cells g(-1) wet weight (10(11) cells per tank). Although the lowest values were often found in tanks that underwent ballast water exchange, the highest concentrations (10(9) to 10(11) cells per tank) were detected in all voyage categories: transoceanic with ballast exchange (TOE), and intra-coastal with exchange (ICE) and without exchange (ICU). For the west coast, 36% of tanks carried detectable quantities of diatoms and there was no statistical difference between ship categories. For the east coast, 60% of tanks contained diatoms; ICU represented a bioinvasion pattern based on more frequent events with consistently lower cell concentrations, whereas ICE and TOE corresponded to less frequent events, though more variable in cell concentrations. Diversity reached 40 taxa per tank, including resting stages and cells that were supposedly growing vegetatively. New records may lead to introduction hypotheses that ought not to be accepted uncritically. Cell viability was tested using the vital stain fluorescein diacetate; parallel counts of protoplasm integrity and chlorophyll autofluorescence revealed that all 3 indicators gave results within the same order of magnitude. Inoculation of 0.2 to 0.5 ml of the slurry into culture media led to the growth of diatoms, even of taxa not initially detected. Within 7 d, cultured assemblages reached cell concentrations equivalent to 1.8 to 4.4 doublings of the original inoculation.

Cysts were isolated from sediment collected from southeast coast of Iran. Individual live cysts were incubated under optimal conditions for germination. Results showed that Protoperidinium oblongum cysts were pentagonal smooth walled and three cysts of this species were identified from Iranian sediment. The germinated cell of P. oblongum was colourless and elongated pentagonal in shape. P. claudican theca cell has a pointed antapical horn with a four sided apical plate. Protoperidinium sp. had dark brown pentagonal cyst. Its germinated cell differed from other Protoperidinium species. Two divergent distally antapical horns formed 90 between the horn and Posterio-lateral of main body edge, thus, comprising a unique species in the Protoperidinium genus. This kind of antapical horn has not been previously reported among Protoperidinium spp.	[Attaran-Fariman, G.] Chabahar Maritime Univ, Fac Marine Sci, Chabahar, Iran; [Khodami, S.] Iranian Fisheries Res Org, Tehran, Iran; [Bolch, C.

J	Odin, GS				Odin, Gilles Serge			Gilianelles: Late Cretaceous microproblematica from Europe and Central America	PALAEONTOLOGY			English	Article						Gilianelles; microproblematica; Upper Cretaceous; evolution; taxonomy; biological crisis	CAMPANIAN-MAASTRICHTIAN BOUNDARY; STRATOTYPE; FRANCE; CHALK	During the last two decades, a range of microfossils have been collected from strata of Late Cretaceous (Coniacian-Maastrichtian) age. The name gilianelles has been coined to accommodate these microproblematica. On the basis of many thousands of specimens, typical features of this group have now been assessed. Distinctive traits are calcareous unilocular, basically axially symmetrical test, in the size range 80-200 mu m, with a single-layered wall of radially arranged crystals, 15 mu m thick, the outer surface with a crochet-like nanostructure, a small-sized aperture (one tenth of test diameter), situated on the upper surface in vivo. Secondary criteria include modification of axial test symmetry into radial or bilateral symmetry, development of expansions, either spiny or laminar and presence of longitudinal and latitudinal ornament. To date, 60 taxa have been described from northern Spain to northern Germany and from Central America. Evolutionary patterns of gilianelles are diverse, with both short- and long-ranging forms, some of which comprise lineages that were affected by a marked crisis dated at about 73 Ma. This event is here illustrated by the tribe Coraliellini, of which a key taxon, Coraliella cognatio, is described as new. Previous interpretations of Gilianelles as dinoflagellate cysts are discussed and rejected.

Pilot Studies of Ozonation for Inactivation of Artemia salina Nauplii in Ballast Water	OZONE-SCIENCE & ENGINEERING			English	Article						Ozone; Total Residual Oxidants (TRO); Artemia salina Nauplii Inactivation; Ballast Water	BROMIDE-CONTAINING WATERS; DINOFLAGELLATE CYSTS; NATURAL-POPULATIONS; HYPOBROMOUS ACID; TREATMENT SYSTEM; MARINE PLANKTON; SHIPS; BROMATE; MICROORGANISMS; DEOXYGENATION	A pilot-plant study was conducted in the Republic of Croatia to determine the applicability of ozonation for inactivation of non-indigenous species and to provide necessary information regarding use of ozone as a ballast water treatment option. Nauplii of the brine shrimp Artemia salina were used as model organisms to investigate the efficacy of ozonation at three different ozone dosages (2.4, 3.7 and 10.9 mg L-1). Mortality of Artemia nauplii at 98.6%, was achieved after 3 h of exposure in ozone-treated water with the highest ozone dosage. Our results indicated that ozonation is a promising treatment for controlling non-indigenous and potentially invasive species; however, to draw more general conclusions, several species with higher level of resistance to ozone are required and will be studied in the future.

Para lytic shellfish toxins (PSTs) were measured in vegetative cells and pellicle cysts prior to feeding and directly after passage through the oyster alimentary canal and defecation as intact cells. Oysters fed with vegetative cells and those fed with pellicle cysts accumulated toxins. One experimental treatment tested for direct uptake of toxins from the water (oysters and A. fundyense cells were separated by a screen); PSTs were not accumulated from the water by the oysters. There were no significant changes in total, per-cell toxicity after passage through the oyster alimentary canal, suggesting limited transfer of toxins from intact cells to the oysters. However, there were statistically significant changes in the toxin composition of cells following gut passage. Vegetative cells and pellicle cysts from feces had increased amounts of saxitoxin (STX) and decreased amounts of gonyautoxin 4 (GTX4) per cell, compared to amounts prior to gut passage. Following gut passage, pellicle cysts showed better survival in the feces than vegetative cells, which is consistent with the view of pellicle-cyst formation as a successful survival strategy against adverse conditions.

Using catalyzed reporter deposition fluorescence in situ hybridization (CARD-FISH), we quantified bacterial attachment to the cells of the dinoflagellate Lingulodinium polyedrum in 39 surface samples collected during a natural bloom in summer 2005 off the coast of La Jolla, California, USA. Using a ribosomal RNA based tunable array with Luminex (R) bead technology, we also quantified the relative abundances of 11 particle-associated bacterial taxa during this time, including 8 members of the Bacteroidetes division. Bacterial colonization of dinoflagellate cells was generally low (mean < 2 bacteria alga(-1)) but increased during the days preceding bloom decline events. This indicates that physical associations, and thus potentially physiological interactions among bacteria and dinoflagellates, changed over the course of the algal bloom cycle. The 11 detected bacterial taxa exhibited diverse patterns of colonization over time, suggesting that they mediated different types of interactions with the dinoflagellates. Some bacterial types were only detected during the early bloom phase, others peaked in abundance during peaks in algal numbers, and still others peaked following bloom decline events. Our data linking the temporal succession of different bacterial colonizers to algal bloom dynamics exemplify the idea that microscale, species-specific interactions between bacteria and protists can result in large-scale ecosystem level changes that can impact phytoplankton community structure in the coastal ocean.

J	Lundgren, V; Granéli, E				Lundgren, Veronica; Graneli, Edna			Influence of altered light conditions and grazers on <i>Scrippsiella trochoidea</i> (Dinophyceae) cyst formation	AQUATIC MICROBIAL ECOLOGY			English	Article						Scrippsiella trochoidea; Cyst formation; Light intensity; Grazer density; Temporary cysts	DINOFLAGELLATE ALEXANDRIUM-OSTENFELDII; PHAEOCYSTIS-GLOBOSA PRYMNESIOPHYCEAE; COPEPOD ACARTIA-TONSA; EGG-PRODUCTION; LIFE-HISTORY; GONYAULAX-TAMARENSIS; TOXIN PRODUCTION; MARINE COPEPODS; TEMPERATURE; GROWTH	We investigated whether or not the presence of copepods and different light conditions induced cyst formation in dinoflagellates. Scrippsiella trochoidea was exposed to Acartia tonsa directly and indirectly (grazer filtrate), in high light and low light conditions. The ingestion, faecal production and egg production of A. tonsa were compared between diets of S. trochoidea vegetative cells and temporary cysts. We found no effect of direct or indirect exposure to A. tonsa on S. trochoidea cyst formation in either high light or low light conditions. Controls and A. tonsa treatments kept in light displayed around 20% temporary cysts, whereas controls and A. tonsa treatments in low light were shown to have 50 to 80% temporary cysts. Thus, low light conditions had a strong effect on temporary cyst formation. No hypnocysts were observed in any experiment, which is probably related to the longer incubation times needed for their observation. Feeding on diets dominated by temporary cysts compared to vegetative cells decreased ingestion by a factor of 2.7, while faecal and egg production decreased by a factor of 2.2 and 2.9, respectively, suggesting that induction of temporary cysts in response to A. tonsa could be a survival strategy. However, S. trochoidea does not possess any grazer-induced defence in terms of temporary cyst formation, as it did not produce temporary cysts when exposed to A. tonsa. Rather, induction of temporary cysts seems to be controlled by decreased light intensity, which is a favorable trait for this species when driven to water depths where light is scarce.

Analysis of Interactions of Brevetoxin-B and Human Serum Albumin by Liquid Chromatography/Mass Spectrometry	CHEMICAL RESEARCH IN TOXICOLOGY			English	Article							NUCLEOPHILIC TARGET; KARENIA-BREVIS; MARINE AEROSOL; HUMAN EXPOSURE; PROTEIN; CYSTEINE; ADDUCTS; BINDING; PLASMA; BLOOD	Brevetoxins are neurotoxins produced by marine dinoflagellates, primarily Karenia brevis, and can cause intoxication and even mortality of marine species, affect human health through the consumption of brevetoxin-contaminated shellfish, and effect respiratory irritation through aerosol exposure at coastal areas. Brevetoxin-A and brevetoxin-B, the major brevetoxins produced in algae, are metabolized to a series of amino acid and peptide-related derivatives in shellfish through the reactions of the amino acid residue cysteine with an alpha,beta-unsaturated aldehyde group. In this paper, covalent interactions between brevetoxin and proteins were investigated using brevetoxin-B and human serum albumin (HSA) as a model. It is demonstrated that both noncovalent and covalent interactions can occur between brevetoxin-B and HSA with in vitro experiments. Covalent adducts of brevetoxin-B and HSA were generated under physiological conditions and reduced with sodium borohydride based on the reaction conditions of single amino acid residues with brevetoxin-B. LC/MS analysis of toxin-treated HSA recognized the formation of the intact protein adducts with primarily one and two toxin molecules attached to one HSA molecule. HSA treated with/without brevetoxin-B was digested with trypsin, trypsin following chymotrypsin, and Pronase, respectively, for LC/MS analysis of adduction sites. Brevetoxin-B was found to react primarily with Cys(34) and His(3) and with His and Lys at other sites of HSA with variable reactivity and with Lys in general the least reactive.

Germination characteristics of <i>Alexandrium catenella</i> cysts from surface sediments in Quartermaster Harbor, Puget Sound, Washington, USA	HARMFUL ALGAE			English	Article						Alexandrium catenella; Dinoflagellate; Cyst; Puget sound; Germination; Mandatory dormancy	GENETIC-MARKERS; RESTING CYSTS; DINOPHYCEAE; IDENTIFICATION; EXCYSTMENT	The dinoflagellate Alexandrium catenella causes frequent outbreaks of paralytic shellfish toxins (PSTs) in Puget Sound, Washington; however, little is known about its basic biology and ecology. Most of what is known is inferred mainly from shellfish toxin records and recent work on cyst distribution and germination potential. We report on a year-long study of cyst dormancy and germination potential based on experiments using surface sediment collected from a shallow embayment, Quartermaster Harbor, in Puget Sound. Cyst abundance in Quartermaster Harbor was 1550-1750 cysts cm(-3) when sediment was collected in mid-October 2006. Germination experiments set up monthly had germination occur in all months when cysts were provided with adequate growth supporting conditions. Germination rates were highest in May and June when 100% germination occurred within 2 days. Longer incubation periods observed for the first two months of the study (November and December) may indicate a mandatory dormancy period of up to 5 months if the majority of cysts were deposited in the sediments following a late summer bloom that apparently occurred in Quartermaster Harbor in 2006 as indicated by Washington State Department of Health's toxin records. The data provide no evidence of an endogenous clock restricting germination to a specific annual timeframe for these shallow water cysts. This contrasts with the presence of a circannual endogenous clock, for deep water cysts of A. fundyense in the Gulf of Maine. The significance of these results is that germination of the A. catenella Puget Sound population appears to be primarily regulated by physiological requirements. However, once physiological requirements are met cysts can germinate rapidly, often within 24 h, when provided with adequate environmental conditions. (C) 2010 Elsevier B.V. All rights reserved.

A species can alternate in its life cycle between four distinct major phases: growth, sex, quiescence and cell death. This implies that the population of a phytoplankton species found in any particular water sample will contain cells that undergo different fates, have strong differentiation in physiology and have different functional roles even if they are genetically identical. The factors regulating transitions among the different phases are still largely unknown but have direct impacts on the ecological distribution of species and on their biogeochemical function. Focused research efforts in recent years have begun to reveal emerging patterns in the variability of phytoplankton life cycle traits. This research has relied both on careful observations in culture and at sea and on making use of new genomics- and transcriptomics-based tools. The study of phytoplankton in the context of their life cycle characteristics opens up new opportunities to address fundamental questions about the physiology and cell biology of these important organisms and creates a new evolutionary and ecological framework for defining phytoplankton functional groups.

The success of dinoflagellates in the spring phytoplankton community has remained poorly understood, as they are expected to be inferior competitors due to their low growth rates and nutrient uptake capacities under nutrient-replete spring conditions. To prevail in the phytoplankton community, dinoflagellates must either be favored by specific environmental settings or possess adaptations, such as allelopathy, to compensate for their competitive disadvantage. Using batch cultures, we studied the allelopathic effects of 3 dominant vernal dinoflagellates-Biecheleria baltica, Gymnodinium corollarium and Scrippsiella hangoei-on 5 typical spring bloom diatoms and 1 cryptophyte. We also tested the effects of the dinoflagellates on each other. Three of the 5 diatoms-Melosira arctica, Skeletonema marinoi and Thalassiosira baltica-were significantly inhibited by cell-free filtrates or live cells of all dinoflagellates. Chaetoceros cf. wighamii and Diatoma tenuis were suppressed by G. corollarium, and D. tenuis was also suppressed by live cells of S. hangoei. In contrast, the cryptophyte Rhodomonas sp. was stimulated by all dinoflagellate species. The effects of dinoflagellate filtrates on other dinoflagellate species were mostly positive, but co-culturing tended to inhibit the growth of the respective target dinoflagellates. As some of the major players of the diatom spring bloom can be suppressed by co-occurring dinoflagellates in culture, we conclude that allelopathy may be one mechanism by which vernal dinoflagellates frequently outcompete diatoms and form intense spring blooms.

Biogeographic distribution of diversity and size-structure of organic-walled dinoflagellate cysts	MARINE ECOLOGY PROGRESS SERIES			English	Article						Dinoflagellate cysts; Biogeography; Diversity; Size	SURFACE SEDIMENTS; CELL-SIZE; MARINE-PHYTOPLANKTON; ALGAL BLOOMS; OCEAN; SEA; PATTERNS; TEMPERATURE; GROWTH; ISLANDINIUM	Global biogeographic patterns and environmental correlates of diversity and size structure of extant marine organic dinoflagellate cysts were determined. Dinoflagellate cyst diversity, like that of many other terrestrial and marine groups, is lowest at the poles and higher at lower latitudes. Temperature is responsible for much of the positive correlation between dinoflagellate cyst diversity and latitude. In contrast, the most obvious correlate with the median size of dinoflagellate cysts is the depth of the water column, especially in warm-water regions, perhaps due to changes in mixing regime and the advantages associated with the lower sinking rates and lower nutrient requirements of smaller species in offshore waters. The unique biogeographic pattern in dinoflagellate cyst diversity may reflect the unique physiological features of dinoflagellates: preference for warm, stable water columns, slower inherent growth rates, and their ability to act as mixotrophs or heterotrophs. Dinoflagellates tend to be 'gleaners', slow-growers adapted to oligotrophic conditions and less sensitive to inorganic nutrient supply, as compared to inorganic resource 'opportunists' with high growth rates, such as diatoms. These ecophysiological differences between dinoflagellates and other functional groups, such as diatoms and coccolithophores, may account for the major differences in the biogeographic and latitudinal diversity gradients between these groups.

A small subset of the phytoplankton may be harmful to human health or to human use of the ecosystem. The species that cause harm are now widely referred to as 'Harmful Algae' with the term 'Harmful Algal Bloom' (HAB) commonly being used to describe their occurrence and effects. In terms of human health, the most important consequence is the production, by some species, of biotoxins. Typically, biotoxin-producing phytoplankton species exist at relatively low densities (c. few hundred or thousand of cells per litre) with the toxins becoming concentrated in the flesh of organisms (particularly bivalve molluscs) that filter feed on phytoplankton. In most cases, there are no adverse effects to these primary consumers, but this concentrating mechanism creates a risk to health if the shellfish are consumed by humans. In this review, we provide an overview of the mechanisms through which marine phytoplankton may cause harm to humans in terms of heath, and the negative effects on the use of ecosystem services. Subsequently, we consider HAB issues in the area we are most familiar with: UK coastal waters. Finally, the methodologies used to safeguard human health from HAB-generated syndromes are discussed.

As one of the most abundant species assigned to calcareous dinophytes (Thoracosphaeraceae, Dinophyceae), Scrippsiella trochoidea is cosmopolitan in distribution, but its taxonomic identity is presently unclear. We collected, isolated and cultivated Scrippsiella trochoidea (strain GeoB*185) from the type locality in the Kiel Fjord (Baltic Sea, Germany). We barcoded the species of the Thoracosphaeraceae based on ITS sequences (including 22 new sequences) and investigated the morphology of strain GeoB*185 by using light, fluorescence and electron microscopy. Numerous distinct lineages that had previously been determined as Scrippsiella trochoidea constituted a species complex rather than a single species. This species complex subsequently comprised three primary clades, for which the strain GeoB*185 was assigned to one of them. We designate an epitype for Scrippsiella trochoidea, which has been prepared from the culture collected in the Kiel Fjord. The unambiguous links between a scientific species name, its protologue, genetic characterization and spatial distribution bear particular importance for character-poor, unicellular organisms such as the dinophytes.

J	Mikkelsen, DM; Witkowski, A				Mikkelsen, Ditte Marie; Witkowski, Anzdrej			Melting sea ice for taxonomic analysis: a comparison of four melting procedures	POLAR RESEARCH			English	Article						Buffer; diatoms; direct melt; flagellates; osmotic stress; sea ice	BALTIC SEA; SALINITIES	The influence of four melting procedures on the taxonomic composition of the sea-ice algal community in Kobbefjord, south-west Greenland, was investigated in April 2008. Direct melting (at 4 and 20 degrees C) was compared with melting in buffering seawater (with salinities of 10 and 30). The sea-ice algal community consisted of diatoms, cysts and several flagellate groups. Direct melting at 20 degrees C differed significantly from one or more of the other melting procedures regarding the flagellate groups chrysophytes, chlorophytes, dinoflagellates and unidentified flagellates, whereas diatom, cyst and cryptophyte abundance was similar, regardless of the melting procedure. Apart from chrysophytes, the three other melting procedures (direct melting at 4 degrees C and buffered in seawater with salinities of 10 and 30) were not statistically different. It is recommended that direct melting at 20 degrees C is avoided, whereas the three slow melting procedures are all comparable. This will enable the future comparison of data from a wide geographic and historical range, thereby increasing our knowledge of sympagic algal communities.

J	Rossi, S; Fiorillo, I				Rossi, Sergio; Fiorillo, Ida			Biochemical features of a <i>Protoceratium reticulatum</i> red tide in Chipana Bay (Northern Chile) in summer conditions	SCIENTIA MARINA			English	Article						Protoceratium reticulatum; red tide; available food; dinoflagellate; fatty acids; upwelling system	DINOFLAGELLATE ALEXANDRIUM-TAMARENSE; FATTY-ACID-COMPOSITION; HARMFUL ALGAL BLOOMS; EL-LOA RIVER; TROPHIC MARKERS; UPWELLING SITE; PHYTOPLANKTON; FOOD; BIOMARKERS; COMMUNITY	Protoceratium reticulatum is considered a potential toxic dinoflagellate. This paper describes a high-frequency monitoring study performed at Chipana Bay (northern Chile), sampling over 48 hours in a near-bottom shallow coastal area to quantify the biochemical features of a red tide dominated by this microscopic algae. This area belongs to the Humboldt Current upwelling system, and is considered highly productive for artisanal fisheries. Total chlorophyll a, total lipids, particulate organic carbon and nitrogen, fatty acids and major phytoplankton group concentration (i.e. dinoflagellates, diatoms, ciliates and cysts) were studied in 7-hour intervals in February 2007. Our results indicate a high concentration of potential available food in the form of lipids ranging from 50 to 300 mu g L-1 for benthic suspension feeders, i.e. bivalves. The dominance of P. reticulation (60-80% of the total cell concentration per litre, ranging from 55x10(3) to 384x10(3) cells L-1) can be considered as a possible interference for harvesting in this productive area, although the toxicity of this algae was not proved in the present study. The main dinoflagellate fatty acid markers [18:0, 18:4(n-3), 20:5(n-3), and 22:6(n-3)] showed high proportions (%) during the short time cycle and in at least two cases [the 18:4 (n-3) and 22:6 (n-3) fatty acids] a highly significant relationship with dinoflagellate concentration (cells L-1). The topographical and benthic structure (mainly kelp forest) of the zone helps to retain particles and nutrients that may in part explain the high productivity and food availability, but the presence of recurrent red tides in this coastal area-if they prove to be toxic-is argued to be a major problem for local fisheries.

J	Figueroa, RI; Garcés, E; Camp, J				Isabel Figueroa, Rosa; Garces, Esther; Camp, Jordi			Reproductive plasticity and local adaptation in the host-parasite system formed by the toxic <i>Alexandrium minutum</i> and the dinoflagellate parasite <i>Parvilucifera sinerae</i>	HARMFUL ALGAE			English	Article						Alexandrium minutum; Cyst formation; Dinoflagellates; Local adaptation; Parvilucifera; Plastic response; Sexuality	SEXUAL REPRODUCTION; DINOPHYCEAE; COEVOLUTION; COMPATIBILITY; AVAILABILITY; POPULATIONS; STRATEGIES; EVOLUTION; INFECTION; FREQUENCY	A parasite threat stimulates adaptive shifts in the life-history strategy (sexual recombination rate) of the toxic bloom-forming dinoflagellate Alexandrium minutum Halim. This microalgae divides asexually when clonal but can also form mobile zygotes (planozygotes) when compatible clones are crossed. Planozygotes usually form resistant dormant stages (resting cysts) although they can also divide. In this study, asexual and sexual cultures were infected with the parasite Parvilucifera sinerae (Perkinsozoa) and the resulting clones classified as susceptible (S), low susceptible (LS), or resistant (R) to the infection. R and LS clones were never of Mediterranean origin, pointing to local adaptation of the parasite. (S x S) crosses were infected faster than either of the parental clones growing asexually. By contrast, (S x R) crosses were resistant to the parasite and produced no resting cysts, even when planozygotes were formed. Therefore, in infected cultures, the planozygotes mainly divided instead of encysting, thus increasing the rate at which recombinant progeny formed. This strategy against infection seems to combine the benefits of quickly producing asexual offspring and increasing recombination. As the susceptibility of the crosses was dependent on parental sexual compatibility, and cultures established by the division of (R x S) planozygotes (F1 offspring) also formed R or LS cultures, resistance may be regulated by several genes or through maternal effects.

Sampling was carried out along 18 transects (2 stations each) during May-June 2007. The identification and counting of raphidophyte cysts were carried out under the inverted microscope and molecular analyses were applied to sediment samples to confirm species-specific identification. Raphidophyte cysts were recorded in almost all stations with maximum abundance of 9 +/- 5 and 12 +/- 3 cysts g(-1) dw for cysts of F. japonica and undetermined Raphidophyceae, respectively. Cyst formation was induced in F. japonica monoclonal cultures under different conditions: shadow-optimal temperature and dark-low temperature treatment; both experiments were performed at two salinity values (30 and 35). Cyst formation (preliminary cysts) was observed in both experiments, although with different encystment rates. However, only a further permanence in the dark at 15 degrees C in microplates led to the formation of mature cysts, probably supported by the possibility to adhere to solid surfaces. Before pre-cyst formation, vegetative cells showed a cytoplasmatic "brown body". (C) 2010 Elsevier B.V. All rights reserved.

(Phylum Dinoflagellata), an Ectoparasite of the Ciliate <i>Tintinnopsis cylindrica</i> Daday 1887, and Its Relationship to <i>Duboscquodinium collini</i> Grasse 1952	JOURNAL OF EUKARYOTIC MICROBIOLOGY			English	Article						Ciliate; dinoflagellate; parasite; taxonomy; tintinnids	SP-NOV DINOPHYCEAE; LAKE TOVEL; PARASITE; FISH; GEN.; DUBOSCQUELLA; REPRODUCTION; PHYLOGENY; OCELLATUM; LETHAL	The dinoflagellate Tintinnophagus acutus n. g., n. sp., an ectoparasite of the ciliate Tintinnopsis cylindrica Daday, superficially resembles Duboscquodinium collini Grasse, a parasite of Eutintinnus fraknoii Daday. Dinospores of T. acutus are small transparent cells having a sharply pointed episome, conspicuous eyespot, posteriorly positioned nucleus with condensed chromosomes, and rigid form that may be supported by delicate thecal plates. Dinospores attach to the host via a feeding tube, losing their flagella, sulcus, and girdle to become spherical or ovoid cells. The trophont of T. acutus feeds on the host for several days, increasing dramatically in size before undergoing sporogenesis. Successive generations of daughter sporocytes are encompassed in an outer membrane or cyst wall, a feature not evident in trophonts. Tintinnophagus acutus differs from D. collini in host species, absence of a second membrane surrounding pre-sporogenic stages, and failure to differentiate into a gonocyte and a trophocyte at the first sporogenic division. Phylogenetic analyses based on small subunit (SSU) ribosomal DNA (rDNA) sequences placed T. acutus and D. collini in the class Dinophyceae, with T. acutus aligned loosely with Pfiesteria piscicida and related species, including Amyloodinium ocellatum, a parasite of fish, and Paulsenella vonstoschii, a parasite of diatoms. Dubosquodinium collini nested in a clade composed of several Scrippsiella species and Peridinium polonicum. Tree construction using longer rDNA sequences (i.e. SSU through partial large subunit) strengthened the placement of T. acutus and D. collini within the Dinophyceae.	[Coats, D.

The formation of resting stages will provide a refuge from unfavourable conditions in the water column, and their successive accumulation in the benthos will constitute a genetic reservoir for future planktonic populations. We have determined the genetic structure of a common bloom-forming diatom, Skeletonema marinoi, in the sediment and the plankton during spring, summer and autumn two subsequent years (2007-2009) in Gullmar Fjord on the Swedish west coast. Eight polymorphic microsatellite loci were used to assess the level of genetic differentiation and the respective gene diversity of the two different habitats. We also determined the degree of genetic differentiation between the seed banks inside the fjord and the open sea. The results indicate that Gullmar Fjord has one dominant endogenous population of S. marinoi, which is genetically differentiated from the open sea population. The fjord population is encountered in the plankton and in the sediment. Shifts from the dominant population can happen, and in our study, two genetically differentiated plankton populations, displaying reduced genetic diversity, occurred in September 2007 and 2008. Based on our results, we suggest that sill fjords maintain local long-lived and well-adapted protist populations, which continuously shift between the planktonic and benthic habitats. Intermittently, short-lived and mainly asexually reproducing populations can replace the dominant population in the water column, without influencing the genetic structure of the benthic seed bank.

In laboratory culture, the optimum temperature for growth of the species is ca. 27 degrees C. Since the species cannot survive in water of temperatures of less than 10 degrees C, it was considered to over-winter in some certain regions as a motile form or resting cyst, and expand its distribution after the temperature increases to a level tolerable for growth. To determine the over-wintering regions and migration pattern of C. polykrikoides, occurrences of the motile cells were surveyed in the coastal and offshore areas of western Kyushu, Japan and south coast of the Korean Peninsula from April 2006 to August 2008. Cells of C. polykrikoides were found at 14 sites during the investigated period. Motile cells occurred throughout the year in Usuka Bay, Hirado of West Japan. From offshore regions of the Goto Islands and off Shin-Nagasaki Fishing Port, motile cells of C. polykrikoides were first detected from late May, and continuously occurred until February in Nama Bay of the Kami-Goto Islands. This first appearance was before red tides of C. polykrikoides reported at coastal areas in western Kyushu. In Korea, this species was first observed in May and disappeared after October in 2007. These occurrence patterns imply that Usuka Bay in Hirado is one of the over-wintering regions in western Kyushu, and also this species is possibly transported into the northern part of the East China Sea by the Tsushima Warm Current every year.

Statistical treatments were performed on 95 surface sediment samples from sites located along the south-western Mexican coast (14.76 degrees N to 24.75 degrees N). Redundancy analysis (RDA) illustrates that the principal parameters correlated with the regional cyst distribution are the distance to the coast and the productivity in the upper water column, which is closely related to upwelling intensity. Empirical observations coupled with RDA provide insight into the spatial coverage of some cyst taxa produced by dinoflagellate species potentially responsible for harmful algal blooms along the coast They also allow the recognition of four zones of assemblages, which are linked to the upwelling intensity and the productivity and characterize La Paz Bay, the south-western Mexican margin (from 15.95 degrees N to 23.11 degrees N), the northern part of the Gulf of Tehuantepec and the southern part of the Gulf of Tehuantepec.

Using cultures of F. duplocampanaeforme isolated from Masan Bay, we investigated feeding, digestion, and prey specificity of this mixotroph. F. duplocampanaeforme fed exclusively on Dinophysis spp. when offered a variety of prey including dinoflagellates, a raphidophyte, a cryptophyte, a ciliate, and diatoms separately. In addition, F. duplocampanaeforme had allelopathic effects on other organisms, including cell immobilization/motility decrease (in Dinophysis acuminata, D. caudata, D. fortii, D. infundibulus, Gonyaulax polygramma, Heterocapsa triquetra, and Prorocentrum triestinum), breaking of cell chains (in Cochlodinium polykrikoides), cell death (in Prorocentrum minimum), and temporary cyst formation (in Scrippsiella trochoidea). F. duplocampanaeforme engulfed whole Dinophysis cells through the sulcus. About 1 h after ingestion, F. duplocampanaeforme became immobile and shed all thecal plates. The ecdysal cyst persisted for similar to 7 h, during which the ingested prey was gradually digested. These observations suggest that F. duplocampanaeforme may play an important role in the Dinophysis population dynamics in the field.

J	Hattenrath, TK; Anderson, DM; Gobler, CJ				Hattenrath, Theresa K.; Anderson, Donald M.; Gobler, Christopher J.			The influence of anthropogenic nitrogen loading and meteorological conditions on the dynamics and toxicity of <i>Alexandrium fundyense</i> blooms in a New York (USA) estuary	HARMFUL ALGAE			English	Article						Alexandrium; Anthropogenic nitrogen loading; delta N-15; Toxin; Climate	HARMFUL ALGAL BLOOMS; PHYSICAL-BIOLOGICAL MODEL; RED TIDE DINOFLAGELLATE; GONYAULAX-TAMARENSIS; WESTERN GULF; AUREOCOCCUS-ANOPHAGEFFERENS; PHYTOPLANKTON COMMUNITIES; UNITED-STATES; NEW-ENGLAND; MAINE	The goal of this two-year study was to explore the role of nutrients and climatic conditions in promoting reoccurring Alexandrium fundyense blooms in the Northport-Huntington Bay complex, NY, USA. A bloom in 2007 was short and small (3 weeks, 10(3) cells L-1 maximal density) compared to 2008 when the A. fundyense bloom, which persisted for 6 weeks, achieved cell densities >10(6) cells L-1 and water column saxitoxin concentrations >2.4 x 10(4) pmol STX eq. L-1. During the 2008 bloom, both deployed mussels (used as indicator species) and wild soft shell clams became highly toxic (1400 and 600 mu g STX eq./100 g shellfish tissue, respectively) resulting in the closure of shellfish beds. The densities of benthic A. fundyense cysts at the onset of this bloom were four orders of magnitude lower than levels needed to account for observed cell densities, indicating in situ growth of vegetative cells was responsible for elevated bloom densities. Experimental enrichment of bloom water with nitrogenous compounds, particularly ammonium, significantly increased A. fundyense densities and particulate saxitoxin concentrations relative to unamended control treatments. The delta N-15 signatures (12-23 parts per thousand) of particulate organic matter (POM) during blooms were similar to those of sewage (10-30 parts per thousand) and both toxin and A. fundyense densities were significantly correlated with POM delta N-15 (p < 0.001). These findings suggest A. fundyense growth was supported by a source of wastewater such as the sewage treatment plant which discharges into Northport Harbor. Warmer than average atmospheric temperatures in the late winter and spring of 2008 and a cooler May contributed to an extended period of water column temperatures optimal for A. fundyense growth (12-20 degrees C), and thus may have also contributed toward the larger and longer bloom in 2008. Together this evidence suggests sewage-derived N loading and above average spring temperatures can promote intense and toxic A. fundyense blooms in estuaries. (C) 2010 Elsevier B.V.

Organic-walled dinoflagellate cyst production, composition and flux from 1996 to 1998 in the central Strait of Georgia (BC, Canada): A sediment trap study	MARINE MICROPALEONTOLOGY			English	Article						Dinoflagellate cysts; Sediment trap; Strait of Georgia; El Nino; Coastal and estuarine systems; Phytoplankton; Dinoflagellates; Biogenic silica	SEA-SURFACE CONDITIONS; RECENT MARINE-SEDIMENTS; JUAN-DE-FUCA; BRITISH-COLUMBIA; ENVIRONMENTAL-FACTORS; SPATIAL-DISTRIBUTION; ESTUARINE SEDIMENTS; NORTH-ATLANTIC; PACIFIC-OCEAN; PRESERVATION	Bi-weekly fluxes of dinoflagellate cysts and assemblage composition were recorded from March 1996 to January 1999 in the central part of the Strait of Georgia (BC, Canada). The study period captured the 1997-98 El Nino event, which was characterized locally by increased Fraser River discharge resulting from earlier than usual snowmelt in 1997 and warmer sea-surface temperatures in 1998. Thirty dinoflagellate cyst taxa were identified in the sediment trap samples. The dinoflagellate cyst flux varied from similar to 600 to 336,200 cysts m(-2) day(-1), with an average of 20,000 cysts m(-2) day(-1). In general, dinoflagellate cyst flux and species composition reflected seasonal variation of water conditions in the Strait of Georgia. Throughout the study period, assemblages were dominated by cysts produced by heterotrophic dinoflagellates, such as Protoperidineaceae (Brigantedinium spp., Quinquecuspis concreta, and Protoperidinium americanum). The greatest abundance of cysts of the potentially toxic Alexandrium spp. was recorded in the spring of 1996. Our results demonstrate that cysts produced by heterotrophic dinoflagellates peak in June each year, during or following diatom blooms, as indicated by biogenic silica flux. Cysts produced by autotrophic taxa were most abundant during August-September. The total annual dinoflagellate cyst flux was lower in 1997 and 1998 than in 1996, mostly due to the bloom of Alexandrium spp. in 1996. Warmer sea-surface temperature and the early spring of 1998 had a positive effect on the production of both autotrophic and heterotrophic dinoflagellates as reflected in the cyst fluxes. Cyst assemblages from sediment trap samples were consistent with a cyst assemblage recovered from a core sample at the same site. (C) 2010 Elsevier B.V. All rights reserved.

OCEAN CLIMATE CHANGE, PHYTOPLANKTON COMMUNITY RESPONSES, AND HARMFUL ALGAL BLOOMS: A FORMIDABLE PREDICTIVE CHALLENGE	JOURNAL OF PHYCOLOGY			English	Review						adaptation; algal blooms; climate change; continuous plankton recorder; ENSO; NAO; ocean acidification; range expansion	NORTH-ATLANTIC OSCILLATION; DINOFLAGELLATE CYSTS; RED TIDES; GYMNODINIUM-CATENATUM; SEDIMENTARY RECORD; POSITIVE FEEDBACK; ATMOSPHERIC CO2; FUTURE; PLANKTON; PACIFIC	Prediction of the impact of global climate change on marine HABs is fraught with difficulties. However, we can learn important lessons from the fossil record of dinoflagellate cysts; long-term monitoring programs, such as the Continuous Plankton Recorder surveys; and short-term phytoplankton community responses to El Nino Southern Oscillation (ENSO) and North Atlantic Oscillation (NAO) episodes. Increasing temperature, enhanced surface stratification, alteration of ocean currents, intensification or weakening of local nutrient upwelling, stimulation of photosynthesis by elevated CO2, reduced calcification through ocean acidification ("the other CO2 problem"), and heavy precipitation and storm events causing changes in land runoff and micronutrient availability may all produce contradictory species- or even strain-specific responses. Complex factor interactions exist, and simulated ecophysiological laboratory experiments rarely allow for sufficient acclimation and rarely take into account physiological plasticity and genetic strain diversity. We can expect: (i) range expansion of warm-water species at the expense of cold-water species, which are driven poleward; (ii) species-specific changes in the abundance and seasonal window of growth of HAB taxa; (iii) earlier timing of peak production of some phytoplankton; and (iv) secondary effects for marine food webs, notably when individual zooplankton and fish grazers are differentially impacted ("match-mismatch") by climate change. Some species of harmful algae (e.g., toxic dinoflagellates benefitting from land runoff and/or water column stratification, tropical benthic dinoflagellates responding to increased water temperatures and coral reef disturbance) may become more successful, while others may diminish in areas currently impacted. Our limited understanding of marine ecosystem responses to multifactorial physicochemical climate drivers as well as our poor knowledge of the potential of marine microalgae to adapt genetically and phenotypically to the unprecedented pace of current climate change are emphasized. The greatest problems for human society will be caused by being unprepared for significant range expansions or the increase of algal biotoxin problems in currently poorly monitored areas, thus calling for increased vigilance in seafood-biotoxin and HAB monitoring programs. Changes in phytoplankton communities provide a sensitive early warning for climate-driven perturbations to marine ecosystems.

Dinoflagellate blooms in upwelling systems: Seeding, variability, and contrasts with diatom bloom behaviour	PROGRESS IN OCEANOGRAPHY			English	Review							SHORT-TERM VARIABILITY; HARMFUL ALGAL BLOOMS; MARINE PLANKTONIC DIATOM; GYMNODINIUM-CATENATUM; RED TIDE; RESTING SPORES; ANCHOR STATION; CHAETOCEROS-PSEUDOCURVISETUS; ENVIRONMENTAL-CONTROL; PHYTOPLANKTON BLOOMS	The influence of diatom bloom behaviour, dinoflagellate life cycles, propagule type and upwelling bloom cycles on the seeding of dinoflagellate blooms in eastern boundary current upwelling systems is evaluated. Winter-spring diatom bloom behaviour is contrasted with upwelling bloom behaviour because their phenology impacts dinoflagellate blooms. The winter-spring diatom bloom is usually sustained, whereas the classical upwelling diatom bloom occurs as a series of separate, recurrent mini-blooms intercalated by upwelling-relaxation periods, during which dinoflagellates often bloom. Four sequential wind-regulated phases characterize upwelling cycles, with each phase having different effects on diatom and dinoflagellate bloom behaviour: bloom "spin up", bloom maximum, bloom "spin down", and upwelling relaxation. The spin up - bloom maximum is the period of heightened diatom growth; the spin down - upwelling-relaxation phases are the periods when dinoflagellates often bloom. The duration, intensity and ratio of the upwelling and relaxation periods making up upwelling cycles determine the potential for dinoflagellate blooms to develop within a given upwelling cycle and prior to the subsequent "spin up" of upwelling that favours diatom blooms. Upwelling diatoms and meroplanktonic dinoflagellates have three types of propagules available to seed blooms: vegetative cells, resting cells and resting cysts. However, most upwelling dinoflagellates are holoplanktonic, which indicates that the capacity to form resting cysts is not an absolute requirement for growth and survival in upwelling systems. The long-term (decadal) gaps in bloom behaviour of Gymnodinium catenatum and Lingulodinium polyedrum, and the unpredictable bloom behaviour of dinoflagellates generally, are examined from the perspective of seeding strategies. Mismatches between observed and expected in situ bloom behaviour and resting cyst dynamics are common among upwelling dinoflagellates. This disassociation suggests unrecognized upwelling system factors that fall within the physical-chemical-biological domain are more important than life cycle in selecting dinoflagellates species having the survival-seeding strategies and ecophysiological adaptations required for growth in physically robust upwelling systems. It is conjectured that diatom life cycles, as a group, are geared towards exploiting seeding opportunities, whereas dinoflagellates have evolved life-cycle behaviour more attuned to survival. The role of ecological dormancy and ecological release from bloom inhibition underlying dinoflagellate bloom irregularity is considered. The expectation that the dinoflagellate species selected to bloom from among the common upwelling flora would be the same in all eastern boundary upwelling systems is not realized.

R. Loeblich III, a widely distributed calcareous cyst-producing dinoflagellate. In this study, three strains (ST-1, ST-D6 and ST-K) of S. trochoidea isolated from the East Asian waters were studied, together with other geographical strains, to resolve their phylogenetic relationships. For the three East Asian isolates, two highly diverse regions of nuclear-encoded ribosomal DNA (rDNA), the 5.8S rDNA and its flanking internal transcribed spacers 1 and 2, and the 5' portion of the large-subunit rDNA (encompassing the "D1" and "D2" domains) were sequenced. Homologous sequences from other geographical isolates were selected from the GenBank database and the phylogenetic relationships were inferred from the molecular data of these strains. Strains of S. trochoidea were found to cluster into three major clades (STR1, STR2 and STR3), as reported in previous studies. Two of the three strains ST-1 and ST-K, were grouped in clade STR2, the other strain, ST-D6, belonged to clade STR3. The intraspecific diversity of S. trochoidea in East Asian waters makes it necessary to carry out phylogenetic investigations in combination with data of biogeography, population dynamics, and life cycle on the ecophysiology of a region.

J	Cavalier-Smith, T				Cavalier-Smith, Thomas			Origin of the cell nucleus, mitosis and sex: roles of intracellular coevolution	BIOLOGY DIRECT			English	Article							POLO-LIKE KINASE; BACTERIAL-DNA SEGREGATION; HORIZONTAL GENE-TRANSFER; MESSENGER-RNA DECAY; CENTRIOLE DUPLICATION; DINOFLAGELLATE CHROMOSOMES; TRYPANOSOMA-BRUCEI; PROTEIN-KINASES; EVOLUTIONARY RELATIONSHIPS; PHYLOGENETIC ANALYSIS	Background: The transition from prokaryotes to eukaryotes was the most radical change in cell organisation since life began, with the largest ever burst of gene duplication and novelty. According to the coevolutionary theory of eukaryote origins, the fundamental innovations were the concerted origins of the endomembrane system and cytoskeleton, subsequently recruited to form the cell nucleus and coevolving mitotic apparatus, with numerous genetic eukaryotic novelties inevitable consequences of this compartmentation and novel DNA segregation mechanism. Physical and mutational mechanisms of origin of the nucleus are seldom considered beyond the longstanding assumption that it involved wrapping pre-existing endomembranes around chromatin. Discussions on the origin of sex typically overlook its association with protozoan entry into dormant walled cysts and the likely simultaneous coevolutionary, not sequential, origin of mitosis and meiosis. Results: I elucidate nuclear and mitotic coevolution, explaining the origins of dicer and small centromeric RNAs for positionally controlling centromeric heterochromatin, and how 27 major features of the cell nucleus evolved in four logical stages, making both mechanisms and selective advantages explicit: two initial stages (origin of 30 nm chromatin fibres, enabling DNA compaction; and firmer attachment of endomembranes to heterochromatin) protected DNA and nascent RNA from shearing by novel molecular motors mediating vesicle transport, division, and cytoplasmic motility. Then octagonal nuclear pore complexes (NPCs) arguably evolved from COPII coated vesicle proteins trapped in clumps by Ran GTPase-mediated cisternal fusion that generated the fenestrated nuclear envelope, preventing lethal complete cisternal fusion, and allowing passive protein and RNA exchange. Finally, plugging NPC lumens by an FG-nucleoporin meshwork and adopting karyopherins for nucleocytoplasmic exchange conferred compartmentation advantages. These successive changes took place in naked growing cells, probably as indirect consequences of the origin of phagotrophy. The first eukaryote had 1-2 cilia and also walled resting cysts; I outline how encystation may have promoted the origin of meiotic sex. I also explain why many alternative ideas are inadequate. Conclusion: Nuclear pore complexes are evolutionary chimaeras of endomembrane-and mitosis-related chromatin-associated proteins. The keys to understanding eukaryogenesis are a proper phylogenetic context and understanding organelle coevolution: how innovations in one cell component caused repercussions on others.

Sediment cores were taken from twelve stations. Twenty-eight dinoflagellate cyst types, representing nine genera, were identified. The most common cysts were those of Lingulodinium machaerophorum, Polykrikos kofoidii, Quinquecuspis concreta and Dubridinium caperatum. Potentially toxic species were widely distributed in the study area. This finding is also important to know the seed-bank areas in the Bay of Izmir.

J	Bravo, I; Figueroa, RI; Garcés, E; Fraga, S; Massanet, A				Bravo, Isabel; Figueroa, Rosa Isabel; Garces, Esther; Fraga, Santiago; Massanet, Ana			The intricacies of dinoflagellate pellicle cysts: The example of <i>Alexandrium minutum</i> cysts from a bloom-recurrent area (Bay of Baiona, NW Spain)	DEEP-SEA RESEARCH PART II-TOPICAL STUDIES IN OCEANOGRAPHY			English	Article						Alexandrium minutum; Ecdysal cysts; Galician rias; Pellicle cysts; Spain; Temporary cysts	RED-TIDE DINOFLAGELLATE; GYMNODINIUM-CATENATUM DINOPHYCEAE; GONYAULAX-POLYEDRA STEIN; OYSTER CRASSOSTREA-GIGAS; LIFE-CYCLE; TOXIC DINOFLAGELLATE; TAYLORI DINOPHYCEAE; SEXUAL REPRODUCTION; HETEROCAPSA-CIRCULARISQUAMA; LINGULODINIUM-POLYEDRUM	The terms "temporary", "pellicle", and "ecdysal" cyst have been employed arbitrarily in the literature of the dinoflagellate life cycle to describe a non-motile and single-layered-wall stage with no mandatory dormancy period, of asexual or sexual origin. These three terms have been used more or less synonymously, but more specific definitions, taking into account morphological and physiological aspects and their roles in dinoflagellate population dynamics, are still needed. To clarify the current terminology, we examine and discuss the usages and foundations of those terms, The background for this discussion is Provided by a comparison of the morphology and germination times of three different types of Alexandrium minutum cysts collected during a seasonal bloom in the Bay of Baiona (NW Spain). The double-walled cysts were similar to the resting cysts reported for this species, but other, thin-walled and thecate cysts were also observed. These latter cyst types needed between 1 and 17 days to germinate and were therefore considered as short-term cysts, in contrast to the 1.5-month dormancy period of resting (hypnozygotic) cysts. Our results showed that the temporal distribution of these short-term cysts during the bloom period followed a pattern very similar to that of vegetative cells. However, resting cysts were only detected at the end of the bloom. In the context of our present knowledge regarding the dormancy and quiescence of dinoflagellate cysts, "temporary" is a very misleading and uncertain term and must be rejected. The term "ecdysal" has been used in reference to thin-walled cysts when ecdysis has been proven; however, ecdysis is not unique to this type of cysts as thick-walled zygotic cysts can be formed thorough ecdysis of a thecate planozygote. In conclusion, based on our current understanding of cysts, the term "pellicle" more appropriately describes single-layered-wall stages. (C) 2009 Elsevier Ltd. All rights reserved.

Outbreeding lethality between toxic Group I and nontoxic Group III <i>Alexandrium tamarense</i> spp. isolates: Predominance of heterotypic encystment and implications for mating interactions and biogeography	DEEP-SEA RESEARCH PART II-TOPICAL STUDIES IN OCEANOGRAPHY			English	Article						Dinoflagellates; Hybridization; Biogeography; Harmful algal blooms; Genotypes; UK; Northern Ireland; Belfast Lough	DINOFLAGELLATE GONYAULAX-TAMARENSIS; CYST FORMATION; SEXUAL REPRODUCTION; GENETIC-MARKERS; RESTING CYSTS; DINOPHYCEAE; IDENTIFICATION; PACIFIC; STRAIN; EXCYSTMENT	We report the zygotic encystment of geographically dispersed isolates in the dinoflagellate species complex Alexandrium tamarense, in particular, successful mating of toxic Group I and nontoxic Group III isolates. However, hypnozygotes produced in Group I/III co-cultures complete no more than three divisions after germinating. Previous reports have Suggested a mate recognition mechanism whereby hypnozygotes produced in co-cultures could arise from either homotypic (inbred) or heterotypic (outbred) gamete pairs. To determine the extent to which each occurs, a nested PCR assay was developed to determine parentage of individual hypnozygotes. The vast majority of hypnozygotes from pairwise Group I/III co-cultures were outbred, so that inviability was a result of hybridization, not inbreeding. These findings support the assertion that complete speciation underlies the phylogenetic structure of the Alexandrium tamarense species complex. Additionally, the ribosomal DNA (rDNA) copy numbers of both hybrid and single ribotype hypnozygotes were reduced substantially from those of haploid motile cells. The destruction of rDNA loci may be crucial for the successful mating of genetically distant conjugants and appears integral to the process of encystment. The inviability of Group I/III hybrids is important for public health because the presence of hybrid cysts may indicate ongoing displacement of a nontoxic population by a toxic one (or vice versa). Hybrid inviability also suggests a bloom control strategy whereby persistent, toxic Group I blooms could be mitigated by introduction of nontoxic Group III cells. The potential for hybridization in nature was investigated by applying the nested PCR assay to hypnozygotes from Belfast Lough, Northern Ireland, a region where Group I and M populations co-occur. Two hybrid cysts were identified in 14 successful assays, demonstrating that Group I and III populations do interbreed in that region. However, an analysis of mating data collected over an 18-year period indicated a leaky pre-mating barrier between ribosomal species (including Groups I and III). Whether the observed selectivity inhibits hybridization in nature is dependent on its mechanism. If the point of selectivity is the induction of gametogenesis, dissimilar ribotypes could interbreed freely, promoting displacement in cases where hybridization is lethal. If instead, selectivity occurs during the adhesion of gamete pairs, it could enable stable coexistence of A. tamarense species. In either case, hybrid inviability may impose a significant obstacle to range expansion. The nested PCR assay developed here is a valuable tool for investigation of interspecies hybridization and its consequences for the global biogeography of these important organisms.

J	Figueroa, RI; Rengefors, K; Bravo, I; Bensch, S				Isabel Figueroa, Rosa; Rengefors, Karin; Bravo, Isabel; Bensch, Staffan			From homothally to heterothally: Mating preferences and genetic variation within clones of the dinoflagellate <i>Gymnodinium catenatum</i>	DEEP-SEA RESEARCH PART II-TOPICAL STUDIES IN OCEANOGRAPHY			English	Article						Dinophyceae; Encystment; Gymnodinium catenatum; AFLPs; Sexual compatibility; Life cycle; Mating; Intraclonal genetic variation	LIFE-CYCLE; GONYAULAX-TAMARENSIS; SEXUAL REPRODUCTION; DINOPHYCEAE; AFLP; DNA; RAPD; EVOLUTION; MUTATION; STRAINS	The chain-forming dinoflagellate Gymnodinium catenatum Graham is responsible for outbreaks of paralytic shellfish poisoning (PSP), a human health threat in coastal waters. Sexuality in this species is of great importance in its bloom dynamics, and has been shown to be very complex but lacks an explanation. For this reason, we tested if unreported homothallic behavior and rapid genetic changes may clarify the sexual system of this alga. To achieve this objective, 12 clonal strains collected from the Spanish coast were analyzed for the presence of sexual reproduction. Mating affinity results, self-compatibility studies, and genetic fingerprinting (amplified fragment length polymorphism, AFLP) analysis on clonal strains, showed three facts not previously described for this species: (i) That there is a continuous mating system within G. catenatum, with either self-compatible strains (homothallic), or strains that needed to be outcrossed (heterothallic), and with a range of differences in cyst production among the crosses. (ii) There was intraclonal genetic variation, i.e. genetic variation within an asexual lineage. Moreover, the variability among homothallic clones was smaller than among the heterothallic ones. (iii) Sibling strains (the two strains established by the germination of one cyst) increased their intra- and inter-sexual compatibility with time. To summarize, we have found that G. catenatum's sexual system is much more complex than previously described, including complex homothallic/heterothallic behaviors. Additionally, high rates of genetic variability may arise in clonal strains, although explanations for the mechanisms responsible are still lacking. (C) 2009 Elsevier Ltd. All rights reserved.

Insight into the factors that determine the distribution and abundance of resting cysts is essential to understanding the dynamics of the vegetative phase. In investigations carried out between January 2005 and January 2008 in Arenys de Mar harbor (northwestern Mediterranean Sea), the spatial and temporal distribution patterns of A. minutum resting cysts and of the sediments were studied during different bloom stages of the vegetative population. Maximum cyst abundance was recorded mainly in the innermost part of the harbor while the lowest abundance always occurred near the harbor entrance, consistent with the distribution of silt-clay sediment fractions. The tendency of cysts in sediments to increase after bloom periods was clearly associated with new cyst formation, while cyst abundance decreased during non-bloom periods. Exceptions to this trend were observed in stations dominated by the deposition of coarse sediments. High correlation between the presence of cysts and clays during non-bloom periods indicates that cysts behave as passive sediment particles and are influenced by the same hydrodynamic processes as clays. In Arenys de Mar, the main physical forcing affecting sediment resuspension is the seiche, which was studied using in situ measurements and numerical models to interpret the observed distribution patterns. During non-bloom periods, cyst losses were smaller when the seiche was more active and at the station where the seiche-induced current was larger. Thus, seiche-forced resuspension appears to reduce cyst losses by reallocating cysts back to the sediment surface such that their burial in the sediment is avoided. The observed vertical profiles of the cysts were consistent with this process. (C) 2009 Elsevier Ltd. All rights reserved.

Considerable differences in their bloom dynamics were observed. G. catenatum blooms occurred in autumn and winter, following the pattern previously reported in the literature: they began off-shore and were advected to the Galician rias when a relaxation of the coastal upwelling occurred. On the other hand, A. minutum blooms developed inside embayments in spring and summer during the upwelling season and were associated with water stability and stratification. Both the vegetative population and the cyst distribution of A. minutum were related to less saline water from freshwater river outputs, which support a saline-gradient relationship postulated herein for this species. Dinoflagellates may produce both long-term double-walled cysts (resting) and short-term pellicle cysts. Resting cyst deposition and distribution in sediments showed that seeding occurred during the blooms of both species. However, the relationship between the cyst distribution in the sediments in Baiona Bay and the intensity and occurrence of C. catenatum blooms, suggests that the latter are not directly related to resting cyst germination. Moreover, the results presented in the present study point to other difference between the two species, such as the detection of pellicle cysts only for A. minutum. Finally, we discuss how the life cycle strategies of these two species may help to explain the different mechanisms of bloom formation reported herein. (C) 2009 Elsevier Ltd. All rights reserved.

The life cycle of these dinoflagellates involves a relatively short period of vegetative growth in early spring (2-3 months), followed by encystment during the first part of May, and a resting period in the form of benthic cysts. The bloom intensity of the Woloszynskia/Scrippsiella complex in the Baltic Sea is spatially variable, with peak abundances in the central and eastern Gulf of Finland, while the species are rare in the Gulf of Riga. During a field survey in late May 2004, we investigated the abundance and distribution of benthic cysts of P. catenata and Woloszynskia spp. ill surface (5 cm) sediments around the Estonian coast. The broad distribution patterns of benthic cysts reflected the overall knowledge of basin-wide planktonic phase distribution of the species. On a finer scale, sediment properties (percent of clay, organic matter content) demarked the accumulation regions of the cysts. Woloszynskia cyst abundances in the surface 5 cm sediment were Lip to 3.2 x 10(6) cysts cm(-2) and Peridiniella cyst abundances were approximately an order of magnitude less, up to 0.3 x 10(6) cysts cm(-2).

Thirty-four cyst morphotypes were recognized belonging to 24 taxa identified at least at the genus level. Cyst abundance in surface sediments ranged from 43 to 828 cysts g(-1) dry weight, with the highest numbers recorded at the most restricted station. Germination experiments allowed confirmation of species identification determined by cyst analysis and provided clonal Cultures of Alexandrium minutum and Gymnodinium nolleri, two of the bloom-forming species in the area. This represents the first record of G. nolleri for the Mediterranean Sea. (C) 2009 Elsevier Ltd. All rights reserved.

Sediment cores were taken from seven stations (December 2006 and August 2007) in Arenys and from eight (October 2006) and ten (May 2007) stations in Olbia. Of the 42 morphotypes found in the sediments collected at the two sites, 27 were identified at the species level, representing 10 genera. The most common cysts were those of Scrippsiella trochoidea, Scrippsiella sp. 2, Gymnodiniales type 1, and Scrippsiella precaria. A number of the morphotypes had not been previously described in the literature. Total cyst abundances varied substantially between the two surveys, with an increased total density in Arenys and a decrease in Olbia. However, at the latter site, a higher abundance of cysts was recorded at more confined sampling stations. Calcareous Peridiniales, belonging to the genus Scrippsiella, dominated the cyst assemblages of both sites, while at some stations higher numbers of Gymnodiniales (Olbia) and Gonyaulacales (Arenys) were determined. Cysts of the toxic species Alexandrium minutum and A. catenella/tamarense were also detected. A. minutum was present at both sites whereas A. catenella/tamarense was found only in Olbia. Peridinium quinquecorne was recovered in the sediments of both sites. In Olbia, cysts of this species were present at high densities and were detected even in deep sediments. Species such as Pentapharsodinium cf. tyrrhenicum, Scrippsiella crystallina, S. lachrymosa, S. precaria, S. trochoidea, Protoperidinium avellanum, P. claudicans, P. compressum, P. conicum, P. cf. minutum, P. oblongum, P pentagonum, P. subinerme, and Zygabikodinium lenticulatum were not detected as motile stages in the study areas. The results of this study, the first on dinoflagellate cyst assemblages at these two sites, further our knowledge of cyst diversity and confirm the importance of embayments and hydrographically confined areas as reservoirs for planktonic dinoflagellates.

A quantitative real-time PCR assay for the identification and enumeration of <i>Alexandrium</i> cysts in marine sediments	DEEP-SEA RESEARCH PART II-TOPICAL STUDIES IN OCEANOGRAPHY			English	Article						Quantitative PCR; Ribosomal; Toxic dinoflagellate; Saxitoxins; Algal blooms; Red tides	LIVING DINOFLAGELLATE CYSTS; HARMFUL ALGAL BLOOMS; FUNDYENSE BLOOMS; UNITED-STATES; GULF; QUANTIFICATION; TAMARENSE; MAINE; DNA; DINOPHYCEAE	Harmful algal blooms (HABs) are a global problem that affects both human and ecosystem health. One of the most serious and widespread HAB poisoning syndromes is paralytic shellfish poisoning, commonly caused by Alexandrium spp. dinoflagellates. Like many toxic dinoflagellates, Alexandrium produces resistant resting cysts as part of its life cycle. These cysts play a key role in bloom initiation and decline, as well as dispersal and colonization of new areas. Information on cyst numbers and identity is essential for understanding and predicting blooms, yet comprehensive cyst surveys are extremely time- and labor-intensive. Here we describe the development and validation of a quantitative real-time PCR (qPCR) technique for the enumeration of cysts of A. tamarense of the toxic North American/Group I ribotype. The method uses a cloned fragment of the large subunit ribosomal RNA gene as a standard for cyst quantification, with an experimentally determined conversion factor of 28,402 +/- 6152 LSU ribosomal gene copies per cyst. Tests of DNA extraction and PCR efficiency show that mechanical breakage is required for adequate cyst lysis, and that it was necessary to dilute Our DNA extracts 50-fold in order to abolish PCR inhibition from compounds co-extracted from the sediment. The resulting assay shows a linear response over 6 orders of magnitude and can reliably quantify >= 10 cysts/cm(3) sediment. For method validation, 129 natural sediment samples were split and analyzed in parallel, using both the qPCR and primulin-staining techniques. Overall, there is a significant correlation (p < 0.001) between the cyst abundances determined by the two methods, although the qPCR counts tend to be lower than the primulin values. This underestimation is less Pronounced in those samples collected from the top 1 cm of sediment, and more pronounced in those derived from the next 1-3 cm of the core. These differences may be due to the condition of the cysts in the different layers, as the top I cm contains more recent cysts while those in the next 1-3 cm may have been in the sediments for many years. Comparison of the cyst densities obtained by both methods shows that a majority (56.6%) of the values are within a two-fold range of each other and almost all of the samples (96.9%) are within an order of magnitude. Thus, the qPCR method described here represents a promising alternative to primulin-staining for the identification and enumeration of cysts. The qPCR method has a higher throughput, enabling the extraction and assay of 24 samples in the time required to process and count 8-10 samples by primulin-staining. Both methods require prior expertise, either in taxonomy or molecular biology. Fewer person-hours per sample are required for qPCR, but primulin-staining has lower reagent costs. The qPCR method might be more desirable for large-scale cyst mapping, where large numbers of samples are generated and a higher sample analysis rate is necessary. While the qPCR and primulin-staining methods generate similar data, the choice of counting method may be most influenced by the practical issue of the different relative costs of labor and materials between the two methods.

Oligonucleotide primers were designed based on the ITS-5.8S and LSU ribosomal gene sequences. The specificity and sensitivity of the PCR assay were assessed using genomic DNA from clonal cultures, plasmid copy number of cloned target sequences, as well as from sediment samples. Qualitative PCR determinations of different cysts in sediment and sediment trap samples were compared to taxonomic examinations by light microscopy. This molecular methodology permitted a fast and specific detection of target cysts in sediment samples. We also detected dinoflagellate and raphidophyte cysts at concentrations not detectable by microscopic methods or that are difficult to identify. The results given by molecular and microscopic methods were comparable. However, higher values of positive detection for target cysts were obtained by PCR than with microscopy. Some taxa were detected in 100% of the samples using PCR, while others were only found in 10% of the samples. The data obtained in this study showed that the PCR-based method is a valid tool for cyst identification in marine sediments. (C) 2009 Elsevier Ltd. All rights reserved.

The use of flow cytometry for species identification and life-cycle studies in dinoflagellates	DEEP-SEA RESEARCH PART II-TOPICAL STUDIES IN OCEANOGRAPHY			English	Article						Alexandrium; DNA content; Flow cytometry; Karlodinium; Sexuality	DNA-CONTENT; CYST FORMATION; SCRIPPSIELLA-HANGOEI; RESTING CYSTS; CELL-CYCLE; DINOPHYCEAE; BLOOM; POPULATIONS; SEXUALITY; DIATOM	The difficulties encountered in attempts to differentiate between dinoflagellate species of the genera Alexandrium and Karlodinium using morphological characteristics are well-known. For this reason, species of these genera were analyzed by flow cytometry to determine whether haploid DNA content served as a valid criterion for species identification. The DNA content of species often confused with each other due to their overlapping size and geographical Occurrence, such as Alexandrium ostenfeldii and the complexes Alexandrium catenella, Alexandrium tamarense, Alexandrium minutum and Alexandrium tamutum, and Karlodinium veneficum and Karlodinium armiger were analyzed. These species differed greatly in DNA content, which provided a means of distinguishing among them. The only cases of DNA overlap involved A. ostenfeldii with Alexandrium peruvianum, and A. catenella with A. tamarense, two groups not yet clearly established either morphologically or genetically. Variability in intraspecies DNA content was observed only in the species K. veneficum. Significant differences between the two A. tamarense strains analyzed were not detected, and the haploid DNA content (63 pg cell(-1)) was very different from the one reported previously for this species (103.5 pg cell(-1)), suggesting cryptic speciation within this group. Flow-cytometric analysis of field samples identified K. veneficum as the causative species of a bloom, suggesting this method as a tool to readily identify species responsible for natural blooms. Additionally, after clonal cultures had been established, cytometric analyses Corroborated the variability in the haploid DNA content of this species, (C) 2009 Elsevier Ltd. All rights reserved.

NOV; TEMPERATURE; PHYTOPLANKTON; ENCYSTMENT; NITROGEN	In Lake Tovel, an oligotrophic and weakly stratified lake, the dinoflagellate Borghiella dodgei Moestrup, Hansen et Daugbjerg, showed a peculiar spatial-temporal pattern with highest abundances in the bottom of the shallow side bay (4 m) along with remarkable abundance variations from year to year. We investigated B. dodgei's growth in laboratory cultures and related results to their implication for bloom formation. B. dodgei was cultivated under different temperature, nutrient and light conditions. Growth rates, cell biovolume, cyst formation and pigment and mycosporine-like amino acids (MAAs) concentrations were determined. Experiments showed that this alga (i) had higher growth rates at low temperatures (< 7A degrees C) and high irradiance levels (similar to 250 mu mol m(-2) s(-1)), (ii) produced higher yields with organic supplements such as peptone, (iii) did not grow in the dark even with organic supplements, (iv) survived for long periods without a light source, (v) synthesised MAAs, (vi) showed an increase in cell volume with nutrient shortage and increasing temperatures (> 7A degrees C) and (vii) had high encystment rates with temperatures > 7A degrees C. These laboratory fingerprints allowed us to construct a theoretical model defining the species' niche. Borghiella needed a mixture of low temperatures, high irradiance levels and sufficient quantities of dissolved organic nitrogen to form blooms. Such a strict combination was probably a transient situation and occurred in oligotrophic Lake Tovel only in early summers followed by heavy spring rains.

Strong annual variation in cyst production characterizes the region. Cyst production of generally all investigated species, including Alexandrium pseudogonyaulax (Biecheler) T. Horig. ex T. Kita et Fukuyo (cyst genus Impagidinium) and Gonyaulax spinifera (Clap. et J. Lachm.) Diesing (cyst genus Nematosphaeropsis) was enhanced with increasing upper water nutrient and trace-element concentrations. Cyst production of Lingulodinium polyedrum (F. Stein) J. D. Dodge was the highest at the transition between upwelling and upwelling-relaxation. Cyst production of Protoperidinium americanum (Gran et Braarud) Balech, Protoperidinium monospinum (Paulsen) K. A. F. Zonn. et B. Dale, and Protoperidinium stellatum (D. Wall) Balech, and heterotrophic dinoflagellates forming Brigantedinium spp. and Echinidinium aculeatum Zonn., increased most pronouncedly during upwelling episodes. Production of Protoperidinium conicum (Gran) Balech and Protoperidinium pentagonum (Gran) Balech cysts and total diatom valves were related, providing evidence of a predator-prey relationship. The export cyst-flux of E. aculeatum, P. americanum, P. monospinum, and P. stellatum was strongly linked to the flux of total diatom valves and CaCO3, whereas the export production of Echinidinium granulatum Zonn. and Protoperidinium subinerme (Paulsen) A. R. Loebl. correlated with total organic carbon, suggesting potential consumption of diatoms, prymnesiophytes, and organic matter, respectively. Sinking velocities were at least 274 m . d(-1), which is in range of the diatom- and coccolith-based phytoplankton aggregates and "slower" fecal pellets. Species-selective degradation did not occur in the water column, but on the ocean floor.	[Zonneveld, Karin A.

Organic-walled dinoflagellate cysts as indicators of oceanographic conditions and terrigenous input in the NW African upwelling region	REVIEW OF PALAEOBOTANY AND PALYNOLOGY			English	Article						organic-walled dinocysts; accumulation rates; aeolian dust; river discharge; upwelling; Cape Ghir; Cape Yubi; Cape Blanc	SEA-SURFACE CONDITIONS; CANARY ISLAND REGION; GYMNODINIUM-CATENATUM; EASTERN BOUNDARY; NORTHWEST AFRICA; INTERANNUAL VARIABILITY; PRODUCTIVITY GRADIENT; MARINE-PHYTOPLANKTON; SPATIAL-DISTRIBUTION; POLYKRIKOS-KOFOIDII	In order to examine the spatial distribution of organic-walled dinoflagellate cysts (dinocysts) in recent sediments related to environmental conditions in the water column, thirty-two surface sediment samples from the NW African upwelling region (20-32 degrees N) were investigated. Relative abundances of the dinocyst species show distinct regional differences allowing the separation of four hydrographic regimes. (1) In the area off Cape Ghir, which is characterized by most seasonal upwelling and river discharge, Lingulodinium machaerophorum strongly dominates the associations which are additionally characterized by cysts of Gymnodinium nolleri, cysts of Polykrikos kofoidii and cysts of Polykrikos schwartzii. (2) Off Cape Yubi, a region with increasing perennial upwelling, L. machaerophorum, Brigantedinium spp., species of the genus Impagidinium and cysts of Protoperidinium stellatum occur in highest relative abundances. (3) In coastal samples between Cape Ghir and Cape Yubi, Gymnodinium catenatum, species of the genus Impagidinium, Nematosphaeropsis labyrinthus, Operculodinium centrocarpum, cysts of P. stellatum and Selenopemphix nephroides determine the species composition. (4) Off Cape Blanc, where upwelling prevails perennially, and at offshore sites, heterotrophic dinocyst species show highest relative abundances. A Redundancy Analysis reveals fluvial mud, sea-surface temperature and the depth of the mixed layer in boreal spring (spring) as the most important parameters relating to the dinocyst species association. Dinocyst accumulation rates were calculated for a subset of samples using well-constrained sedimentation rates. Highest accumulation rates with up to almost 80,000 cysts cm(-2) ka(-1) were found off Cape Ghir and Cape Yubi reflecting their eutrophic upwelling filaments. A Redundancy Analysis gives evidence that primary productivity and the input of fluvial mud are mostly related to the dinocyst association. By means of accumulation rate data, quantitative cyst production of individual species can be considered independently from the rest of the association, allowing autecological interpretations. We show that a combined interpretation of relative abundances and accumulation rates of dinocysts can lead to a better understanding of the productivity conditions off NW Africa.

Bioassay methods for detection of <i>N</i>-palmitoylbrevetoxin-B2 (BTX-B4)	TOXICON			English	Article						Brevetoxin; BTX-B2; N-palmitoylbrevetoxin-B2 (BTX-B4); Bioassay; Metabolism; Fatty acid conjugate; Neurotoxic shellfish poisoning	OYSTER CRASSOSTREA-VIRGINICA; RED-TIDE DINOFLAGELLATE; SENSITIVE SODIUM-CHANNELS; PTYCHODISCUS-BREVIS; NEW-ZEALAND; BREVETOXIN METABOLISM; CONTROLLED EXPOSURES; GREENSHELL MUSSELS; KARENIA-BREVIS; GYMNODINIUM	Brevetoxins (BTXs) are a class of cyclic polyether toxins produced by the dinoflagellate Karenia brevis. These substances are subject to extensive conjugative metabolism in shellfish. BTX-B forms a conjugate with cysteine and is oxidized and reduced to yield BTXB2, which is further modified by fatty acid addition via cysteine amide linkage to give biologically active brevetoxin metabolites. In this study, we evaluated the commonly used in vitro (ELISA, radioimmunoassay, receptor binding assay and N2A cytotoxicity assay) and in vivo mouse brevetoxin bioassays for the detection of the brevetoxin fatty acid conjugate N-palmitoylBTX-B2, and compared the results to those for dihydroBTX-B and BTX-B2. The receptor binding assay for N-palmitoylBTX-B2 showed comparable sensitivity to that for dihydroBTX-B, and an 11-fold higher sensitivity than for BTX-B2. Although the ELISA showed similarly high sensitivity to dihydroBTX-B and BTX-B2, with EC50 values of ca. 0.26 ng/ml, it was 23 times less sensitive to N-palmitoylBTX-B2. On the other hand, the N2A cytotoxicity assay was highly sensitive to N-palmitoylBTX-B2, with an EC50 of 0.15 ng/ml, but was 12- and 40-fold less sensitive to dihydroBTX-B and BTX-B2, respectively. The relative sensitivity of the N2A cytotoxicity assay for each of these metabolites paralleled that of the mouse bioassay (relative LD50 values 1:20:30 for N-palmitoylBTX-B2:dihydroBTX-B:BTX-B2). We conclude that the most sensitive bioassay for dihydroBTX-B and BTX-B2 is the ELISA, whereas the N2A cytotoxicity assay is most sensitive for N-palmitoylBTX-B2. Published by Elsevier Ltd.

Marine ecosystems are specially affected by introduced species of toxin-producing microalgae. Ships ballast water has been considered the major vector in dispersion of phytoplankton. However, most ships do not use ballast water. Alternatively, we propose that the biofouling recovering the underwater body of ships is the main cause of microalgal dispersion. Antifouling paints (containing tributyltin, TBT or other toxics) are used to coat the bottoms of ships to prevent biofouling. After sampling biofouling recovering the underwater body of ships we demonstrate that numerous coastal, oceanic and toxin-producing microalgae species proliferates attached on bottoms of ships directly on TBT antifouling paint. These microalgae species should be resistant variants because antifouling paints rapidly destroy sensitive wild type microalgae. Consequently, the key to explain microalgae species transport via ships biofouling is know the mechanisms that allow to these species to survive long time attached to antifouling paint. A fluctuation analysis demonstrate that genetic adaptation by rare spontaneous mutation, which occurs by chance prior to antifouling exposure is the mechanism allowing adaptation of microalgae to antifoulig paints and their dispersion in the ships biofouling. Around 3 TBT-resistant mutants per each 10(-4) wild type sensitive cells occurs in microalgal population. This assures a rapid colonization of ships bottoms to travel long-distances.

Previous studies at selected Scottish sites have shown diversity within the genus Alexandrium. In order to examine the distribution, diversity and toxicity of Alexandrium populations around the Scottish coast, historic cyst and cell data were compiled and cultures established from sediment and water samples. Historic data showed high cell densities of Alexandrium in Shetland, Orkney, the Western Isles and mainland east coast. Low abundances of Alexandrium cysts were observed along the west coast. Four species of Alexandrium (A. tamarense, A. ostenfeldii, A. minutum and A. tamutum) were established in laboratory culture and identified using morphological criteria. Sequencing of LSU rDNA from isolates of A. ostenfeldii, A. minutum and A. tamutum confirmed their identification and showed them to be similar to other European strains. Alexandrium tamarense, identified by morphological criteria, was observed to have a widespread distribution around the coast. Both toxin-and non toxin-producing strains of this species were isolated, suggesting the presence of A. tamarense Groups I and III. Alexandrium ostenfeldii was isolated from the east coast and Shetland Isles and was observed to produce both spirolide and PSP toxins. Alexandrium tamutum was identified from cultures isolated from Shetland and Orkney, the most northerly observation of this species to date. PSP toxins were not detected in isolates of A. minutum from the east coast and Orkney or of A. tamutum under the culture conditions used. This study has highlighted the diversity of Alexandrium in Scottish waters and reveals the requirement for temporal and regional studies on a species level in order to understand the variation in cell densities and PSP toxicity that is observed on an annual and decadal scale.

Re-classification of <i>Pheopolykrikos hartmannii</i> as <i>Polykrikos</i> (Dinophyceae) based partly on the ultrastructure of complex extrusomes	EUROPEAN JOURNAL OF PROTISTOLOGY			English	Article						Chloroplast; Dinoflagellate; Peridinin; Polykrikoids; Taeniocyst-nematocyst complex; Ultrastructure	GYMNODINIUM-SENSU-STRICTO; FLAGELLAR APPARATUS; DINOFLAGELLATE POLYKRIKOS; MORPHOLOGY; PHYLOGENY; SCHWARTZII; KOFOIDII; CYST; NOV; SSU	Athecate, pseudocolony-forming dinoflagellates have been classified within two genera of polykrikoids, Polykrikos and Pheopolykrikos, and different views about the boundaries and composition of these genera have been expressed in the literature. The photosynthetic polykrikoid Pheopolykrikos hartmannii, for instance, was originally described within Polykrikos and is now known to branch closely with several Polykrikos species in molecular phylogenetic analyses of ribosomal gene sequences. In this study, we report the first ultrastructural data for this species and demonstrate that Ph. hartmannii has all of the features that characterize the genus Polykrikos, including the synapomorphic "taeniocystnematocyst complex". We also demonstrate that the ultrastructure of the chloroplasts in Ph. hartmannii conforms to the usual peridinin-containing chloroplasts of most photosynthetic dinoflagellates, which improves inferences about the origin(s) and evolution of photosynthesis within the genus. After taking into account all of the ultrastructural data on polykrikoids presented here and in the literature, this species is re-classified to its original status as Polykrikos hartmannii.

The motile cell of the heterotrophic dinoflagellate Protoperidinium crassipes contains cholesterol, 4,24-dimethylcholestan-3-ol, dinosterol, dinostanol, and 4-tetramethylcholestan-3-ol as major free sterols. The dinosterol concentrations of heterotrophic dinoflagellates are about 4-12 times higher than those of autotrophic species, suggesting that the heterotrophic dinoflagellate is an important source of dinosterol in some sediments. 4-Tetramethylcholestan-3-ol has not been reported in cultured samples of other heterotrophic dinoflagellates. The difference in 4-methyl sterol composition in heterotrophic dinoflagellates may be related to the feeds used during the culture experiment. The resting cyst of P. umbonatum var. inaequale contains 4-methylcholestan-3-ol, 4,24-dimethylcholestan-3-ol, dinosterol, dinostanol, and C-31 Delta(5.22)-sterol as major free sterols. The C-31 Delta(5.22)-sterol has not been reported in cultured samples of motile cells from dinoflagellates. This compound might be produced during the resting stage, and thus may serve as a potential biomarker for the resting cysts of dinoflagellates.

This species has been monitored in water column samples, but its spatial distribution in sediments is poorly understood. To address this area, geographic distribution of C. polykrikoides and morphologically similar species Gymnodinium impudicum in surface sediments of Korea was investigated using species-specific real-time PCR probes targeting the internal transcribed spacer 2 rRNA gene. PCR-inhibitory substances in sediment samples were removed by dilution of DNA extracts from the field samples for preventing false-negative detection. G. impudicum was widely distributed in sediments from East, South, and Yellow Seas. C. polykrikoides was prevalent in sediments from South Sea whereas it was not detected in sediments from East and Yellow Seas. These results indicate that these dinoflagellates may persist in surface sediment likely in the form of cyst and their "seed beds" may exist in sediments of South Sea where blooms of C. polykrikoides occur annually.

Distribution patterns of recent organic-walled dinoflagellate cysts in relation to environmental parameters in the Mediterranean Sea	PALYNOLOGY			English	Article						Mediterranean Sea; dinoflagellate cysts; temperature; productivity; preservation; eutrophication	BENGUELA UPWELLING REGION; NORTHERN NORTH-ATLANTIC; RECENT MARINE-SEDIMENTS; SURFACE SEDIMENTS; ADRIATIC SEA; SPATIAL-DISTRIBUTION; SEASONAL OCCURRENCE; WEST-COAST; NILE CONE; ASSEMBLAGES	To determine the relationship between the spatial dinoflagellate cyst distribution and oceanic environmental conditions, 34 surface sediments from the Eastern and Western Mediterranean Sea have been investigated for their dinoflagellate cyst content. Multivariate ordination analyses identified sea-surface temperature, chlorophyll-a, nitrate concentration, salinity, and bottom oxygen concentration as the main factors affecting dinoflagellate cyst distribution in the region. Based on the relative abundance data, two associations can be distinguished that can be linked with major oceanographic settings. (1) An offshore eastern Mediterranean regime where surface sediments are characterized by oligotrophic, warm, saline surface water, and high oxygen bottom water concentrations (Impagidinium species, Nematosphaeropsis labyrinthus, Pyxidinopsis reticulata and Operculodinium israelianum). Based on the absolute abundance, temperature is positively related to the cyst accumulation of Operculodinium israelianum. Temperature does not form a causal factor influencing the accumulation rate of the other species in this association. Impagidinium species and Nematosphaeropsis labyrinthus show a positive relationship between cyst accumulation and nitrate availability in the upper waters. (2) Species of association 2 have highest relative abundances in the Western Mediterranean Sea, Strait of Sicily/NW Ionian Sea, and/or the distal ends of the Po/Nile/ Rhone River plumes. At these stations, surface waters are characterized by (relative to the other regime) higher productivity associated with lower sea-surface temperature, salinity, and lower bottom water oxygen concentrations (Selenopemphix nephroides, Echinidinium spp., Selenopemphix quanta, Quinquecuspis concreta, Brigantedinium spp. and Lingulodinium machaerophorum). Based on both the absolute and relative abundances, Selenopemphix nephroides is suggested to be a suitable indicator to trace changes in the trophic state of the upper waters. The distribution of Lingulodinium machaerophorum is related to the presence of river-influenced surface waters, notably the Nile River. We suggest that this species might form a suitable marker to trace past variations in river discharge, notably from the Nile.

J	Gómez, F; Moreira, D; López-García, P				Gomez, Fernando; Moreira, David; Lopez-Garcia, Purificacion			<i>Neoceratium</i> gen. nov., a New Genus for All Marine Species Currently Assigned to <i>Ceratium</i> (Dinophyceae)	PROTIST			English	Article						alveolate evolution; Dinoflagellata; Neoceratium gen. nov.; new combination; resting cyst; SSU rDNA phylogeny	FINE-STRUCTURE; DINOFLAGELLATE; IDENTIFICATION; PROTISTS; PLANKTON; HISTORY; SAMPLES; TREES; PCR	The dinoflagellate genus Ceratium contains marine and freshwater species. Freshwater species possess six cingular plates, thick plates in the concave ventral area and usually develop a third hypothecal horn. The marine Ceratium species (>62 species) possess five cingular plates and thin plates in the concave ventral area; a third hypothecal horn is atypical. Resting cysts, a common feature in the freshwater species, are unreported in marine species. We illustrate for the first time resting cysts in marine Ceratium species (C. furca and C. candelabrum). We obtained small subunit ribosomal RNA gene (SSU rDNA) sequences of 23 Ceratium species (more than one third of the total marine species described so far), with representatives of the four acknowledged subgenera. Phylogenetic analyses including the type species, the freshwater C. hirundinella, showed that the four available sequences of freshwater species formed a strongly supported subclade, very distant from the marine cluster. Our data support the splitting of Ceratium sensu lato into two genera. Ceratium sensu stricto should be reserved for fresh water species possessing six cingular plates (three cingular plates in dorsal view). The new genus name, Neoceratium gen. nov. should be applied to the marine species of Ceratium sensula to that possess five cingular plates (two cingular plates in dorsal view).

With a MW of 2680, it is one of the largest nonpolymeric natural products ever found. Its complex structure has been elucidated and total synthesis has been achieved. With an LD50 Of 25 ng/kg for rabbits (the most sensitive species), it is one of the most lethal marine toxins. It binds to the Na,K-ATPase specifically with a K-D of 20 pM. It has a unique action on the Na,K-ATPase, converting the pump into an ion channel and resulting in K+ efflux, Na+ influx and membrane depolarization. As a result palytoxin causes a wide spectrum of secondary pharmacological actions. By acting like a key to unlock the internal structure of the Na,K-ATPase, palytoxin holds promise as a useful tool for investigation of the pump molecule. (C) 2009 Elsevier Ltd.

It has been shown that G. baicalense var. minor Ant. is a life stage of G. baicalense, whose species size is smaller than it is given in the diagnosis. Morphology of the living vegetative cells of G. baicalense is close to that of G. wigrense Wolosz. These species share ecological features. The vegetative cells form endogenous resting cysts. The sexual reproduction takes place in the period of the mass development of the species. The author believes that it is a relict species, which formed in the Ice age.

However, parallel RNA-based surveys are required in order to verify whether the species detected are in fact metabolically active in such extreme environments. The Black Sea is the World's largest anoxic basin but remains undersampled with respect to molecular eukaryotic diversity studies. Here, we report the distribution of active eukaryotes (18S rRNA-based survey) along a vertical nutrient and redox gradient in the water column and surface sediments of the Black Sea. A wide variety of eukaryotes were active in suboxic deep waters. Notably, certain species were active but escaped detection during a parallel 18S rDNA survey. The 18S rDNA survey from surface sediments yielded taxa of pelagic origin but none of these were identified from the water column at the time of sampling. Our data also indicate that gene transcripts do not always provide unequivocal proof that active microorganisms are indigenous to a specific position in an environmental gradient, because certain zoo- and phytoplankton species were still viable with detectable 18S rRNA in up to 300-year-old sulfidic sediments that underlie similar to 830 in of sulfidic waters.

T.; Matsuoka, Kazumi			<i>Protoperidinium tricingulatum</i> sp nov (Dinophyceae), a new motile form of a round, brown, and spiny dinoflagellate cyst	PHYCOLOGICAL RESEARCH			English	Article						cyst; Echinidinium; heterotrophic dinoflagellate; Islandinium; Protoperidinium tricingulatum sp; nov	SURFACE SEDIMENTS; ULTRASTRUCTURE; PERIDINIALES; PRODUCTIVITY; INDICATORS; OCEAN; GULF	P>A small, broadly ovoidal and heterotrophic dinoflagellate containing round, brownish, and spiny cyst was found in the water column of Huibertsplaat in the Wadden Sea off the coast of the Netherlands. This dinoflagellate had these conspicuous morphological characters: a five-sided first apical plate (1'), only three cingular plates, and an extremely small first antapical plate. Based on these morphological features, Protoperidinium tricingulatum Kawami, vanWezel, Koeman et Matsuoka is described as a new species. The flagellar pore of P. tricingulatum is covered with a small fin, which rises from the left side of the right sulcal plate to the large V-shaped posterior sulcal plate. This feature suggests that P. tricingulatum is assigned to the Abe's Monovela Group. The cyst stage of P. tricingulatum was positively linked to the vegetative stage by comparison of the ribosomal 5.8S rDNA, internal transcribed spacers (ITS1 and ITS2). Living cysts of P. tricingulatum are round, brownish, and covered with many slender spines bearing capitate or cauliforate distal ends. The cyst also possesses a theropylic archeopyle formed by a slit corresponding to parasutures between three apical and two apical intercaraly plates. These morphological characters indicate that this species is morphologically related to two dinoflagellate cyst-genera Islandinium and Echinidinium.

Our results show that, in nutrient-enriched environments, diatoms are particularly benefited from the nutrients supplied and, as a consequence, heterotrophic dinoflagellates that feed on the diatoms can be more abundant than autotrophic dinoflagellates. In short-core sediment records, a marked shift in autotrophic-heterotrophic dinoflagellate cyst compositions occurred at a depth of approximately 9-10 cm corresponding to the timing of the 1970s industrialization around Gwangyang Bay. This tentatively indicates that diatom and dinoflagellate communities here have undergone a considerable change mainly due to increased nutrient loadings from both domestic sewage effluent and industrial pollution. Our study suggests a possible potential use of dinoflagellate cysts in providing retrospective information on the long-term effects of coastal eutrophication.

Here, we present new observations regarding their life cycle based on coastal plankton samples and incubations and analyze their molecular phylogeny using the small subunit ribosomal RNA gene (SSU rDNA) as a marker. In contrast to the typical stages already documented for its life cycle, we observed that D. pseudolunula dinospores may exceptionally differentiate inside a globular cyst. Despite its parasitic life style, the cysts and dinospores of D. pseudolunula contain chlorophyll a. We obtained the first SSU rDNA sequences for the genera Chytriodinium (the type C roseum and C affine) and Dissodinium (D. pseudolunula). Classical taxonomical schemes have ascribed these genera to the order Blastodiniales. However, our SSU rDNA-based phylogenetic analysis shows that these ectoparasites form a clade in the Gymnodinium sensu stricto group, unarmored dinokaryotic dinoflagellates of the order Gymnodiniales. They branch in a subgroup composed of warnowiids, polykrikoids, the type of Gymnodinium, G. fuscum and G. aureolum. Although Chytriodinium and Dissodinium appear to be relatives based on SSU rDNA phylogeny, feeding and host specificity, their life cycles are substantially different. Based on these data we consider that the type of life cycle is a poor criterion for classification at the family level. We suggest that the morphology of the infective cell is probably the most reliable phenotypic characteristic to determine the systematic position of parasitic dinoflagellates. (C) 2009 Elsevier GmbH.

An integrated water/sediment approach to study plankton (a case study in the southern Adriatic Sea)	JOURNAL OF MARINE SYSTEMS			English	Article						Resting stages; Cyst bank; Plankton; South Adriatic	VERTICAL-DISTRIBUTION; RESTING EGGS; SEDIMENTS	In marine coastal areas many planktonic species produce resting stages (cysts) that sink to the bottom. Integrated sampling from both the water column (to collect active stages). and sediments (to collect cysts), could be useful to achieve more complete information about plankton composition. In the framework of the "INTERREG II Albania-Italy Project" an oceanographic survey was carried out aboard the r/v "Italica" from 20 to 31 October 2000. The survey interested the northern Albanian coast (Gulf of Drin) and the northern Apulian coast (Gulf of Manfredonia) on the opposite sides of the South Adriatic Sea. The plankton was collected from 14 stations. A total of 188 categories were recognized in plankton samples. Among those categories, 130 species were recognized (87 of phytoplankton, 43 of microzooplankton), and only 53 (40.8%) resulted common to both the Adriatic sides. A total of 69 cyst morphotypes were recognized in sediment samples; 38 of them were classified at the level of species. A statistical analysis of the microzooplankton species abundance showed a segregation of the two areas better than that obtained with the phytoplankton. Cyst distribution in the sediments showed a good gulf-segregation too. In addition, they allowed us to find complementary information, particularly for dinoflagellates. The most abundant species in the water column were not equally dominant as resting stages in the sediments. Sediment sampling allowed further information about the composition of the plankton communities, and suggested us to search for a new method to enhance the yield of less abundant cysts.

The diatom <i>Chaetoceros</i> in ships' ballast waters - survivorship of stowaways	ACTA BOTANICA CROATICA			English	Article	20th International Diatom Symposium	SEP 07-13, 2008	Dubrovnik, CROATIA	Croatian Botan Soc, Univ Zagreb, Fac Sci, Algol Grp		Diatom; Chaetoceros; phytoplankton; non-indigenous species; ballast water; resting stage; spore; ultrastructure	RESTING SPORES; DINOFLAGELLATE CYSTS; SEDIMENTS; TRANSPORT; SURVIVAL; BACILLARIOPHYCEAE; GERMINATION; COAST; SEA; BAY	Ship ballast water discharged by vessels into the receiving port is recognised today as all important vector for the spread of non-indigenous species and facilitates the introduction of potential invasive species. Here, we report on 18 species (of about 30 identified), both vegetative cells and spores, of the diatom genus Chaetoceros Ehrenberg found in ballast water collected from ships arriving at Canadian ports on the West Coast (WC), East Coast (EC) and the Great Lakes (GL). We found live, vegetative Chaetoceros cells (one of the most abundant taxa) in 49% of the 57 ballast water samples. The highest density of viable spores enumerated in our counts was 414 cells L(-1). In 62% of 52 samples examined Using scanning electron microscopy (SEM), Chaetoceros spores were found, though fewer live, identifiable spores were found Using light microscopy. Three reportedly harmful species, C. convolutus, C. danicus, C. debilis were encountered in WC samples, and additionally, C. cf. hispidus, a species not yet reported from Canada. C. ceratosporus and C. cf. subsecundus, to date reported only from the EC of the USA, now have been transported to the port of Vancouver, British Columbia. Our findings contribute to the assessment of the effectiveness of ballast water treatment via water exchange, and serve to evaluate the diversity of diatom vegetative cells and spores transported in ballast water tanks.

The capacity of herbivorous zooplankton, such as Calanus, to biosynthesize and store large amounts of lipids during the short and intense spring bloom is a fundamental adaptation which facilitates the large production in these ecosystems. These energy-rich lipids are rapidly transferred through the food chain to Arctic seals. The fatty acids and stable isotopes from harp seal (Phoca groenlandica) and hooded seal (Cystophora cristata) off East Greenland as well as their potential prey, were analysed. The results were used to describe the lipid dynamics and energy transfer in parts of the East Greenland ecosystem. Even if the two seal species showed considerable overlap in diet and occurred at relatively similar trophic levels, the fatty acid profiles indicated that the bases of the food chains of harp and hooded seals were different. The fatty acids of harp seals originate from diatom-based food chain, whereas the fatty acids of hooded seals originate from dinoflagellate and the prymnesiophyte Phaeocystis pouchetii-based food chain. Stable isotope analyses showed that both species are true carnivores on the top of their food chains, with hooded seal being slightly higher on the food chain than harp seal. (C) 2008 Elsevier Ltd.

In laboratory-produced cysts, the dormancy period was estimated to be less than 2 weeks. A vernalization period was not required prior to germination. However, after 1 month of dark-storage at 6 degrees C, excystment was obtained 2-3 days from re-exposure to favourable conditions thereby suggesting that germination was sychronized. Germination patterns and germling cell viability in laboratory-produced cysts were similar to those exhibited in natural cysts. The following conditions optimized germination: temperature between 14 and 26 degrees C, salinity between 30 and 38 psu and light exposure for >1 h at 100 mu moles photons m(-2)s(-1). Similar conditions prevailed at the commencement of and during Alexandrium blooms in Thau lagoon, suggesting that cysts may germinate shortly after being recruited from sediment re-suspensions. Accordingly, cyst bank germinations contribute to the initial seeding of blooms, and subsequently germinations of newly formed cysts can help to maintain blooms.In cyst banks, the high germination capabilities seem, however, to be counter-balanced by the low viability of cyst progeny, as estimated from the realized seeding ratio.

Investigation of the 2006 <i>Alexandrium fundyense</i> bloom in the Gulf of Maine: In-situ observations and numerical modeling	CONTINENTAL SHELF RESEARCH			English	Article						Harmful algal bloom; Coastal circulation; Gulf of Maine; Bio-physical interaction	FLORIDA SHELF CIRCULATION; PHYSICAL-BIOLOGICAL MODEL; TEMPERATURE BUDGET; COASTAL CURRENT; WESTERN GULF; DINOFLAGELLATE; MECHANISMS; TRANSITION; SURFACE	In-situ observations and a coupled bio-physical model were used to study the germination, initiation, and development of the Gulf of Maine (GOM) Alexandrium fundyense bloom in 2006 Hydrographic measurements and comparisons with GOM climatology indicate that 2006 was a year with normal coastal water temperature. salinity. current and river runoff conditions. A. fundyense cyst abundance in bottom sediments preceding the 2006 bloom was at a moderate level compared to other recent annual cyst survey data We used the coupled bio-physical model to hindcast coastal circulation and A fundyense cell concentrations. Field data including water temperature. salinity, velocity time series and Surface A fundyense cell concentration maps were applied to gauge the model's fidelity The coupled model is capable of reproducing the hydrodynamics and the temporal and spatial distributions of A fundyense cell concentration reasonably well. Model hindcast solutions were further used to diagnose physical and biological factors controlling the bloom dynamics Surface wind fields modulated the bloom's horizontal and vertical distribution. The initial cyst distribution was found to be the dominant factor affecting the severity and the interannual variability of the A. fundyense bloom Initial cyst abundance for the 2006 bloom was about 50% of that prior to the 2005 bloom As the result, the time-averaged gulf-wide cell concentration in 2006 was also only about 60% of that in 2005 In addition, weaker alongshore currents and episodic upwelling-favorable winds in 2006 reduced the spatial extent of the bloom as compared with 2005.

J	Murik, O; Kaplan, A				Murik, Omer; Kaplan, Aaron			Paradoxically, prior acquisition of antioxidant activity enhances oxidative stress-induced cell death	ENVIRONMENTAL MICROBIOLOGY			English	Article							CHLAMYDOMONAS-REINHARDTII; ASCORBATE PEROXIDASE; PERIDINIUM-GATUNENSE; ARABIDOPSIS-THALIANA; GENE-EXPRESSION; PLANTS; DINOFLAGELLATE; PHOTOSYNTHESIS; METACASPASES; METABOLISM	P>Oxidative stress has been implicated in the induction of programmed cell death in a wide variety of organisms. Acquiring antioxidant capacity is thought to enhance the viability of cells challenged by a subsequent oxidative stress. Counter-intuitively, we show that in two phytoplankton species, Chlamydomonas reinhardtii and Peridinium gatunense, representing the green and red plastid lineages, oxidative stress induced cell death in cultures that already possessed high antioxidant activity but not in cells that exhibited low activity. Cell death of low antioxidant possessing cultures was markedly enhanced by the addition of dehydroascorbate, a product of ascorbate peroxidase (APX), but not of ascorbate or reduced glutathione, and was preceded by increased metacaspase expression and activity. These data suggested that the level of APX and its products, strongly upregulated by oxidative stress, serves as a possible surveillance signal, reporting that the cells already experienced an earlier oxidative stress. Our data presents a novel role of APX in antioxidant activity and response to oxidative stress in photosynthetic microorganisms. Elimination of cysts production by phytoplankton cells that were already damaged by oxidative stress (indicated by the rise in oxidized proteins) as the inoculum for the following year's population may be the evolutionary trigger for this phenomenon.

PHYCOLOGICAL RESEARCH			English	Article						Baldinia; Biecheleria; Borghiella; Borghiellaceae; freshwater dinoflagellates; molecular phylogeny; ultrastructure	LAKE TOVEL; COMB. NOV; ULTRASTRUCTURE; DINOPHYCEAE; PHYLOGENY	P>The well known freshwater dinoflagellate Woloszynskia pseudopalustris is transferred to the new genus Biecheleria, based on the very unusual structure of the eyespot (comprising a stack of cisternae), the apical apparatus of a single elongate amphiesma vesicle, the structure of the resting cyst, and molecular data. Biecheleria is phylogenetically related to Symbiodinium and Polarella of the family Suessiaceae. This family, which extends back to the Jurassic, is redefined with the eyespot (Type E sensu Moestrup and Daugbjerg) and apical apparatus as diagnostic features, unknown elsewhere in the dinoflagellates. Biecheleria also comprises the brackish water species Biecheleria baltica sp. nov. (presently identified as Woloszynskia halophila) and the marine species Biecheleria natalensis (syn. Gymnodinium natalense). Gymnodinium halophilum described in 1952 by B. Biecheler but apparently not subsequently refound, is transferred to Biecheleria. The Suessiaceae further includes the marine species Protodinium simplex, described by Lohmann in 1908 but shortly afterwards (1921) transferred to Gymnodinium by Kofoid and Swezy and subsequently known as Gymnodinium simplex. It only distantly related to Gymnodinium. A new family, the Borghiellaceae, is proposed for the sister group to the Suessiaceae, based on eyespot structure (Type B of Moestrup and Daugbjerg), the morphology of the apical apparatus (if present), and molecular data. It presently comprises the genera Baldinia and Borghiella. Cells of Biecheleria pseudopalustris and B. baltica contain a microtubular strand (msp) associated with vesicles containing opaque material. Such structures are known in other dinoflagellates to serve as a peduncle, indicating that the two species may be mixotrophic.

PHYCOLOGICAL RESEARCH			English	Article						dinoflagellates; phylogeny; phytoplankton; taxonomy; ultrastructure; woloszynskioids	FLAGELLAR APPARATUS; LAKE TOVEL; COMB. NOV; DINOPHYCEAE; PHYLOGENY; POLYKRIKOS; LIGHT	P>An isolate of the very small marine dinoflagellate Biecheleriopsis adriatica gen. et sp. nov. (12-15 mu m long) has been examined by light, scanning and transmission electron microscopy, combined with partial sequencing of nuclear-encoded large subunit rRNA. Biecheleriopsis is a genus of thin-walled dinoflagellates, related to Biecheleria and the taxonomic group of Polarella, Protodinium and Symbiodinium, the latter comprising mainly symbionts of marine invertebrates. The mixotrophic Biecheleriopsis adriatica is characterized by: (i) a special type of apical furrow apparatus; (ii) an eyespot of Type E sensu Moestrup and Daugbjerg; (iii) an unusual type of pyrenoid; and (iv) a spiny resting cyst. Thin sections showed the presence a fibrous connection between the flagellar apparatus and a finger-like extension of the nucleus ('rhizoplast'). It forms a physical connection between the flagella and the nucleus. This unusual structure has previously been considered to characterize the 'true' gymnodinioids, represented by Gymnodinium sensu Daugbjerg et al. and related forms. However, the apical furrow apparatus and the nuclear envelope of Biecheleriopsis are woloszynskioid rather than gymnodinioid. The related genus Biecheleria lacks a rhizoplast, and it also lacks a 51-base pair fragment of domain D2 of the large subunit rRNA, which is present in other woloszynskioids. A physical connection between the flagellar apparatus and the nucleus mediated by a fibrous structure is known in other groups of protists, for example, the 'rhizoplast' of many heterokont flagellates, some green algal flagellates, etc. The phylogenetic significance of a rhizoplast in two groups of dinoflagellates that are only distantly related is presently difficult to assess.

Transcriptional Profiling of <i>Saccharomyces cerevisiae</i> Upon Exposure to Saxitoxin	ENVIRONMENTAL SCIENCE & TECHNOLOGY			English	Article							MOLECULAR CHARACTERIZATION; SULFUR ASSIMILATION; COPPER; IRON; YEAST; GENES; EXPRESSION; IDENTIFICATION; HOMEOSTASIS; METABOLISM	Saxitoxin is a potent neurotoxin produced by several species of dinoflagellates and cyanobacteria. The molecular target of saxitoxin in higher eukaryotes is the voltage-gated sodium channel; however, its target in lower eukaryotic organisms remains unknown. The goal of this study was to obtain the transcriptional fingerprint of the model lower eukaryote Saccharomyces cerevisiae upon exposure to saxitoxin to identify potential genes suitable for biomarker development Microarray analyses identified multiple genes associated with copper and iron homeostasis and sulfur metabolism as significantly differentially expressed upon exposure to saxitoxin; these results were verified with quantitative reverse-transcriptase PCR (qRT-PCR). Additionally, the qRT-PCR assays were used to generate expression profiles in a subset of the differentially regulated genes across multiple exposure times and concentrations, the results of which demonstrated that overall, genes tended to respond in a consistent manner to the toxin. In general, the genes encoding the metallothioneins CUP1 and CRS5 were induced following exposure to saxitoxin, while those encoding the ferric/cupric reductase FRE1 and the copper uptake transporter CTR1 were repressed. The gene encoding the multicopper ferroxidase FET3, part of the high-affinity iron uptake system, was also induced in all treatments, along with the STR3 gene, which codes for the cystathionine beta-lyase found in the methionine biosynthetic pathway.

NOV; PHYLOGENETIC ANALYSIS; ELECTRON-MICROSCOPY; FUSCUM DINOPHYCEAE; AUSTRALIAN WATERS; RDNA SEQUENCES; ULTRASTRUCTURE	A naked dinoflagellate with a unique arrangement of chloroplasts in the center of the cell was isolated from the northern Baltic proper during a spring dinoflagellate bloom (March 2005). Morphological, ultrastructural, and molecular analyses revealed this dinoflagellate to be undescribed and belonging to the genus Gymnodinium F. Stein. Gymnodinium corollarium A. M. Sundstrom, Kremp et Daugbjerg sp. nov. possesses features typical of Gymnodinium sensu stricto, such as nuclear chambers and an apical groove running in a counterclockwise direction around the apex. Phylogenetic analyses based on partial nuclear-encoded LSU rDNA sequences place the species in close proximity to G. aureolum, but significant genetic distance, together with distinct morphological features, such as the position of chloroplasts, clearly justifies separation from this species. Temperature and salinity experiments revealed a preference of G. corollarium for low salinities and temperatures, confirming it to be a cold-water species well adapted to the brackish water conditions in the Baltic Sea. At nitrogen-deplete conditions, G. corollarium cultures produced small, slightly oval cysts resembling a previously unidentified cyst type commonly found in sediment trap samples collected from the northern and central open Baltic Sea. Based on LSU rDNA comparison, these cysts were assigned to G. corollarium. The cysts have been observed in many parts of the Baltic Sea, indicating the ecologic versatility of the species and its importance for the Baltic ecosystem.

Dinoflagellate cyst production on the southern Namaqua shelf of the Benguela upwelling system	JOURNAL OF PLANKTON RESEARCH			English	Article							SURFACE SEDIMENTS; WEST-COAST; RED TIDE; BAY; SCRIPPSIELLA; AFRICA; BLOOMS; EUTROPHICATION; LINGULODINIUM; DINOPHYCEAE	To study dinoflagellate cyst production in the southern Benguela, a sediment trap was deployed for a period of 3.5 years at a single station located downstream of the Cape Columbine upwelling cell on the southern Namaqua shelf. The cyst assemblage of surface sediments below the trap was also investigated. Twenty-nine different cyst types were recorded of which 25 were from the sediment trap, and 22 from the surface sediments. The flux of cysts followed a clear seasonal trend with an initial peak in spring followed by a major peak in autumn; with a mean flux for the entire period of deployment of 1.4 x 10(6) cysts m(-2) day(-1). Of the cysts recovered from the trap, those of heterotrophic dinoflagellates were six times more abundant than those of autotrophic dinoflagellates. The study also revealed the presence of cysts of species previously unrecorded in the plankton of the southern Benguela, specifically the toxic dinoflagellate Lingulodinium polyedrum.

All the taxa are illustrated with photomicrographs and descriptions of the resting and vegetative stages are given, including synonymy, size variation, distribution in Mexico, and global distribution, when known. As a result of cyst germination assays, the previously unknown cyst-theca relationship of P. globosum was described. We also confirmed the presence of the vegetative stage of P. denticulatum in the Gulf of California and heterospory in G. spinifera from Bahia Concepcion. Cultures of G. spinifera and P. globosum were successfully established.

Understanding Causes and Impacts of the Dinoflagellate, <i>Cochlodinium polykrikoides</i>, Blooms in the Chesapeake Bay	ESTUARIES AND COASTS			English	Article						Cochlodinium polykrikoides; Nitrogen uptake; Chesapeake Bay; Fish mortality	NITROGEN; GYMNODINIALES; DINOPHYCEAE; MORTALITY; CYSTS; PRODUCTIVITY; MIXOTROPHY; SALINITY; DYNAMICS; REGIONS	During August and September 2007, the lower Chesapeake Bay and its tributaries experienced a massive bloom of Cochlodinium polykrikoides Margalef (> 10(4) cells per milliliter) that persisted for over a month, was extremely patchy, and at times penetrated into the Atlantic Ocean. The onset of the bloom coincided with a period of intense rainfall and stormwater runoff after a protracted summer drought period. Genetic evidence showed this species to be distinct from many Asian strains but similar to other North American strains. Populations dominated by C. polykrikoides took up a variety of nitrogenous compounds to support their growth and were able to mobilize additional sources of organic nutrients through peptide hydrolysis. Bioassays determined that C. polykrikoides exerted a lethal affect on juvenile fish and shellfish, causing 100% mortality of juvenile fish (Cyprinodon variegates) in less than 24 h and 20% mortality in juvenile American oysters (similar to 21 mm; Crassostrea virginica) within 72 h.

We tested the effect of increasing temperature while providing nutrient-replete conditions as well as the effect of ambient nutrient (N, P) deficiency. The results revealed different encystment cues and patterns in the three species. While depletion of ambient nitrogen and subsequent internal N stress were the primary factors behind cyst production of G. corollarium, higher temperature led to substantial encystment of S. hangoei and W. halophila without a direct link to cellular nutrient physiology. In W. halophila, N limitation induced a transition of the population to small cells presumably representing gametes, but this process was not followed by cyst formation. Phosphorus stress was not directly linked to cyst formation in any of the species. Our data indicate that both reliable token cues (such as temperature) and ultimate causes (for example, nutrient depletion) for encystment are likely involved in the cyst-formation process. Such duality might provide an explanation for multiple triggers inducing encystment in laboratory settings and the lack of evidence for a direct relationship between nutrient depletion and cyst formation in the field.

J	Smith, BC; Persson, A; Wikfors, GH				Smith, Barry C.; Persson, Agneta; Wikfors, Gary H.			A particle separator used to concentrate Dinoflagellate cysts from sediment	LIMNOLOGY AND OCEANOGRAPHY-METHODS			English	Article							RESTING CYSTS	A device has been developed to separate and collect large numbers of dinoflagellate cysts from sediment samples of several liters volume. The apparatus consists of a 152.5 x 44.5 x 38-cm fiberglass tank with a 20-mu m screen inserted diagonally across the long dimension, creating an inclined plane as the bottom of a settling tank. A peristaltic pump delivers resuspended bottom material to the top of the deep end of the tank. The particles settle according to mass and friction as the water moves to a drain near the top center of the shallow end of the screen. The desired particles can be vacuumed from specific areas of the screen and further refined with a final sieving step. More than 16 L marine mud were processed in this apparatus at one time. In a reference sediment sample collected from beneath New Haven Harbor (Connecticut, USA), cyst recovery was 25% for living cysts. The sediment in the uppermost part of the sorter had approximately 376 times more cysts/mL than the sediment originally added. The cyst fraction (particles 20-100 mu m) contained ten times more cysts in the uppermost part of the sorter than at the middle or lower ends. Cysts within the cyst-rich zone of the separator settled differently depending upon species, size, and morphology.

Proteins related to green algal striated fiber assemblin are present in stramenopiles and alveolates	PROTOPLASMA			English	Article						Assemblin; Alveolates; Flagellar apparatus; Phytophthora; Oomycetes; Striated fiber; Stramenopiles; Thalassiosira	MICROTUBULE-ASSOCIATED FIBERS; SEGMENTED COILED-COIL; PHYTOPHTHORA-CINNAMOMI; FLAGELLAR APPARATUS; 2-NM FILAMENTS; SF-ASSEMBLIN; PREDICTION; CENTRIN; SPORES; FORMS	In green algae, striated fiber assemblin (SFA) is the major protein of the striated microtubule-associated fibers that are structural elements in the flagellar basal apparatus. Using Basic Local Alignment Search Tool (BLAST) searches of recently established databases, SFA-like sequences were detected in the genomes not only of green algal species but also of a range of other protists. These included species in two alveolate subgroups, the ciliates (Tetrahymena thermophila, Paramecium tetraurelia) and the dinoflagellates (Perkinsus marinus), and two stramenopile subgroups, the oomycetes (Phytophthora sojae, Phytophthora ramorum, Phytophthora infestans) and the diatoms (Thalassiosira pseudonana, Phaeodactylum tricornutum). Together with earlier identification of SFA-like sequences in the apicomplexans, these results indicate that homologs of SFA are present across the alveolates and stramenopiles. Antibodies raised against SFA from the green alga, Spermatozopsis similis, react in immunofluorescence assays with the two basal bodies and an anteriorly directed striated fiber in the flagellar apparatus of biflagellate Phytophthora zoospores.

Dynamics of potentially harmful microalgae in a confined Mediterranean Gulf-Assessing the risk of bloom formation	HARMFUL ALGAE			English	Article						Abundance-occupancy; Heterocapsa; Karlodinium; Scrippsiella; Toxic microalgae	ALGAL BLOOMS; DOMOIC ACID; PHYTOPLANKTON; EUTROPHICATION; DINOPHYCEAE; CALIFORNIA; CERATIUM; SEA	The population dynamics of potentially harmful microalgae was investigated in the semi-enclosed shallow Gulf of Kalloni, Greece (Aegean Sea, Eastern Mediterranean), during a 2-year period from August 2004 to March 2006. A total of 21 potentially harmful microalgae (bloom-forming and/or toxic) were identified including 3 diatoms and 18 dinoflagellates. The densities of each species were analyzed in time and space and in relation to environmental parameters. Some species such as Alexandrium insuetum, Heterocapsa circularisquama, Karlodinium veneficum, Scrippsiella trochoidea, and Ceratium spp. developed high cell concentrations, particularly during a Pseudo-nitzschia calliantha winter bloom. Other species such as Dinophysis caudata, Ostreopsis ovata, Prorocentrurn minimum, and Protoperidinium crassipes were rare or appeared in small numbers. Densities of the most abundant species were closely associated with freshwater nutrient-rich inputs during winter, being negatively correlated with temperature and salinity and positively correlated with nitrogen. The spatial distribution of the abundant species exhibited a marked increase towards the inner part of the gulf, close to the main freshwater inputs, whereas some species were mainly concentrated in the dilute surface layer (1 m depth). Examination of the abundance-occupancy relationship revealed that the species more prone to bloom are those with wide spatial distribution and frequent presence throughout the year such as the diatom P. calliantha. Although blooms of cyst-forming species are rarer, an increased risk can be foreseen under favorable resource supply and environmental conditions during winter. (C) 2009 Elsevier B.V.

Synthetic hybrid molecules of caffeine and eudistomin D from tunicates Eudistoma sp. were found to show better potency as adenosine receptor ligands than caffeine, and one of them exhibits potent activity for adenosine receptors tested, especially for A(3) subtype. Potent cytotoxic polyene macrolides from a tunicate Cystodytes sp. were found to be potent osteoclast inhibitors and to inhibit vacuolar type H+-ATPase (V-ATPase) of both mammalian and yeast cells. Amphidinolactones A and B are new macrolides from a dinoflagellate Amphidinium sp., and a potent cytotoxic macrolide from another strain was found to target actin cytoskeleton. Theonezolide A, a long-chain polyketide from a sponge Theonella sp., induces a drastic shape change in platelets by reorganization of microtubules. The stereochemistry of many chiral centers in theonezolide A was elucidated by spectral data and chemical means. Metachromins L-Q are new sesquiterpenoid quinones with an amino acid residue, while nakijiquinones E and F were the first dimeric sesquiterpenoid quinones possessing a 3-aminobenzoate moiety. Halichonadin E is the first hetero-dimeric sesquiterpenoid with eudesmane and aromadendrane skeletons linked through a urea fragment isolated from a sponge Halichondria sp. Pyrinadine A and nakinadine A are novel bis-pyridine alkaloids from sponges, while nagelamides are new bromopyrrole alkaloids from a sponge Agelas sp.

Multivariate analysis of the dinoflagellate cyst relative abundances and environmental parameters of the water column shows that sea-surface temperature, salinity, marine productivity and bottom water oxygen are the factors that relate significantly to the distribution patterns of individual species in the region. The composition of cyst assemblages and dinoflagellate cyst concentrations allows the identification of four hydrographic regimes; 1) the northern regime between 17 and 14 degrees N characterized by high productivity associated with seasonal coastal upwelling, 2) the southern regime between 12 and 6 degrees N associated with high-nutrient waters influenced by river discharge 3) the intermediate regime between 14 and 12 degrees N influenced mainly by seasonal coastal upwelling additionally associated with fluvial input of terrestrial nutrients and 4) the offshore regime characterized by low chlorophyll-a concentrations in upper waters and high bottom water oxygen concentrations. Our data show that cysts of Polykrikos kofoidii, Selenopemphix quanta, Dubridinium spp., Echinidinium species, cysts of Protoperidinium monospinum and Spiniferites pachydermus are the best proxies to reconstruct the boundary between the NE trade winds and the monsoon winds in the subtropical eastern Atlantic Ocean. The association of Bitectatodinium spongium, Lejeunecysta oliva, Quinquecuspis concreta, Selenopemphix nephroides, Trinovantedinium applanatum can be used to reconstruct past river outflow variations within this region.

Sexual reproduction was by conjugation of isogametes, and plasmogamy was completed in 25-60 min after the conjugation started and produced a planozygote with one transverse and two longitudinal flagella, then a cyst was formed. Cysts were round or elliptical. The cyst size was 37.5-50.0 mu m in diameter. The surface of cysts was smooth, and there was no paratabulation. Encystment through sexual reproduction was observed in two of 28 pairs, which included seven self-crossings, by use of seven nonaxenic clonal strains. No planozygote formation or encystment was found in any of the self-crossings, indicating that this species is heterothallic. Successful excystment was observed when the cysts, which had been preserved at 10 degrees C in the dark for 3 mo, were incubated under light conditions at 25 degrees C, thus showing that this species has a similar life cycle as reported in A. tamarensel catenella tamiyavanichii.

However, it is unknown whether the binucleate condition is permanent or not and how the diatom nucleus behaves during the life history processes. In this sense, it is also unknown if there is a sexual cycle or a resting stage during the life history of this species, two key aspects necessary to understand the life history strategy of this dinoflagellate. To answer these questions, life history and cell cycle studies were performed with the following results: (i) Kryptoperidinium foliaceum has a sexual cycle and in the dinoflagellate strains studied, the binucleate condition is permanent. Sexuality in the host was confirmed by the presence of fusing gamete pairs and planozygotes in clonal cultures (revealing homothallism), but signs of meiosis in the endosymbiont were not observed. The endosymbiont nucleus likely fuses first, because fusing gamete pairs were found to have two dinoflagellate nuclei but only one endosymbiont nucleus. After complete gamete fusion, the planozygotes had apparently normal endosymbiont and dinoflagellate nuclei. (ii) Asexual division studies using flow cytometry showed that the S phase in the endosymbiont (diatom) nucleus starts 6 - 8h later than in the host nucleus, but there was no evidence of mitosis in the former. (iii) Sexual and asexual cysts were formed in culture. Neither cysts from natural samples nor those formed in culture exhibited a dormancy period before germination. (C) 2009 Elsevier GmbH.

BIOGEOGRAPHIC ANALYSIS OF THE GLOBALLY DISTRIBUTED HARMFUL ALGAL BLOOM SPECIES <i>ALEXANDRIUM MINUTUM</i> (DINOPHYCEAE) BASED ON rRNA GENE SEQUENCES AND MICROSATELLITE MARKERS	JOURNAL OF PHYCOLOGY			English	Article						A; lusitanicum; A; minutum; biogeography; genotype; harmful algal blooms; LSU rRNA; microsatellites; phylogeny	COASTAL WATERS; TAMARENSE DINOPHYCEAE; DINOFLAGELLATE CYSTS; COMPLEX DINOPHYCEAE; TOXIN PRODUCTION; MUTATION-RATES; NEW-ZEALAND; RED TIDE; PHYLOGENY; DNA	The toxic dinoflagellate Alexandrium minutum Halim is one of three species that comprise the "minutum" species complex. This complex is notable due to its role in the etiology of paralytic shellfish poisoning (PSP). Recent increases in PSP incidence and the geographic expansion of toxin-producing Alexandrium dinoflagellates have prompted the intensive examination of genetic relationships among globally distributed strains to address questions regarding their present distribution and reasons for their apparent increase. The biogeography of A. minutum was studied using large subunit ribosomal DNA gene (LSU rRNA) and internal transcribed spacer (ITS) sequences and genotypic data from 12 microsatellite loci. rRNA gene and ITS sequencing data distinguished between two clades, herein termed the "Global" and the "Pacific"; however, little to no resolution was seen within each clade. Genotypic data from 12 microsatellite loci provided additional information regarding genetic relationships within the Global clade, but it was not possible to amplify DNA from the Pacific clade using these markers. With the exception of isolates from Italy and Spain, strains generally clustered according to origin, revealing geographic structuring within the Global clade. Additionally, no evidence supported the separation of A. lusitanicum and A. minutum as different species. With the use of microsatellites, it is now possible to initiate studies on the origin, history, and genetic heterogeneity of A. minutum that were not previously possible using only rRNA gene sequence data. This study demonstrates the power of combining a marker with intermediate resolution (rRNA sequences) with finer-scale markers (microsatellites) to examine intraspecies variability among globally distributed isolates and represents the first effort to employ this technique in A. minutum.

CONSUMPTION OF <i>SCRIPPSIELLA LACHRYMOSA</i> RESTING CYSTS BY THE EASTERN OYSTER (<i>CRASSOSTREA VIRGINICA</i>)	JOURNAL OF SHELLFISH RESEARCH			English	Article						Scrippsiella lachrymose; Crassostrea virginica; dinoflagellate; cyst; oyster; grazing	CALCAREOUS DINOFLAGELLATE CYSTS; POPULATION-DYNAMICS; MARINE-SEDIMENTS; HARMFUL ALGAE; DINOPHYCEAE; TROCHOIDEA; AUSTRALIA; PASSAGE; EVENTS; GUT	Scrippsiella spp. resting cysts, unlike many other dinoflagellate cysts. Possess an outer layer of calcite beneath which is a thin sporopollenin wall. This feature may affect cyst survival through the digestive tract of benthic organisms, when they consume the cysts. The extent of digestibility is related to the degree to which grazing by benthic organisms could influence a benthic cyst population. To test consumption and digestion of a representative Scrippsiella cyst by one benthic grazer, the eastern oyster (Crassostrea virginica) was fed culture-produced resting cysts or the dinoflagellate Scrippsiella lachrymosa under controlled conditions. Cyst recovery from no-oyster, control containers was 97%; therefore, digestive destruction of cysts could be quantified as the difference between cysts added to experimental containers containing oysters and the number of intact cysts recovered after a period of oyster feeding. In each treatment, 18% of the cysts were destroyed after being ingested at a cell density of 43.4 cysts/mL and 11% were digested at a higher cell density (263,2 cysts/mL). Cysts were observed to become rounded and turn yellow after first losing the outer, calcareous wall as a first step in digestion. In fecal-pellet samples, contents from broken cysts could be found as well as intact cysts and rounded yellow cysts. Viability of ingested cysts was not evaluated, but it seems that Scrippsiella cysts are relatively resistant to digestion by oysters.

The longitudinal furrows on the hypocone of P. kofoidii differentiate it from P. schwartzii. Differences in surface ornamentations on the cysts of P. schwartzii and P. kofoidii were considered as important morphological features to differentiate these two species. Many researchers accepted that the cyst of P. schwartzii was characterized by reticulate ornaments and P kofoidii by separate, rod-like processes. However, encystment/excystment experiments carried out in previous studies clarified that the P. kofoidii cyst has coarse reticulate ornaments, not rod-like processes. Further subsequent observations on these relationships have indicated that rod-like processes develop not on cysts of P kofoidii but on cysts of P. schwartzii. In combination with morphological observations, phylogenetic analyses of the small subunit and large subunit rDNA sequences, directly collected from vegetative cells and living cysts of P. kofoidii and P. schwartzii confirmed these findings on the cyst motile relationships and thus the criteria for the identification of cysts required revision. Furthermore morphologically intermediate forms, which sometimes occur, are identical to the cysts of P. schwartzii based on the molecular data of a single cell PCR technique for living cysts.

Environmental factors influencing the variability of <i>Lingulodinium polyedrum</i>? and <i>Scrippsiella trochoidea</i> (Dinophyceae) cyst production	CIENCIAS MARINAS			English	Article						Baja California; cysts; dinoflagellates; Lingulodinium; Scrippsiella	WALLED DINOFLAGELLATE CYSTS; BENGUELA UPWELLING SYSTEM; GULF-OF-CALIFORNIA; TODOS-SANTOS BAY; SURFACE SEDIMENTS; BAJA-CALIFORNIA; GONYAULAX-TAMARENSIS; POPULATION-DYNAMICS; MEXICO; TEMPERATURE	This study analyzes the temporal variability of the abundance of Lingulodinium polyedrum and Scrippsiella trochoidea resting cysts in surface sediments, as well as the temporary cysts and vegetative cells of L. polyedrum in the upper water column of Todos Santos Bay (Baja California, Mexico). Samples were collected monthly from January 2002 to June 2005 at four sites. Multidimensional scaling analysis and analysis of similarities revealed that resting cysts are distributed heterogeneously according to the sedimentary environment. Surface water temperature, inorganic dissolved phosphate, and the abundance of temporary cysts were the main factors influencing the abundance of L, polyedrum resting cysts, while the variability of temporary cysts was explained by the abundance of planktonic cells. Scrippsiella trochoidea resting cysts showed no statistical relationship with the environmental factors considered. Local runoff during the rainy season and sewage from the city of Ensenada contribute to the eutrophication of the bay. This is an important factor for future blooms since inorganic dissolved nitrate + nitrite and daylight hours during the spring-summer season are not limiting factors for dinoflagellate growth. After the dinoflagellate blooms, there was massive cyst production of both species, and the new cysts settled oil the surface sediments. Surface water temperatures between 17 degrees C and 22.5 degrees C during spring-summer appear to trigger excystment in these species.	[Pena-Manjarrez, J.

The term calcispheres is inconsistently used, the morphological and taxonomical concepts are mostly ill-defined and a formal definition is lacking. To resolve this issue, we propose, in analogy with the erection of the Acritarcha for organic microfossils of unknown origin, a new group called Calcitarcha, including all calcareous microfossils with a central cavity for which the biological affinities remain unknown.

J	Kamikawa, R; Nishimura, H; Sako, Y				Kamikawa, Ryoma; Nishimura, Hiroshi; Sako, Yoshihiko			Analysis of the mitochondrial genome, transcripts, and electron transport activity in the dinoflagellate <i>Alexandrium catenella</i> (Gonyaulacales, Dinophyceae)	PHYCOLOGICAL RESEARCH			English	Article						Alexandrium; dinoflagellate; electron transporter; mitochondria; rRNA fragmentation	TOXIC DINOFLAGELLATE; MESSENGER-RNAS; GENES; ORGANIZATION; OXIDASE; COMPLEX; SYSTEM; CYSTS	The mitochondrial (mt) genomes of dinoflagellates are not completely sequenced due to frequent recombination events resulting in a shortage of information about the dinoflagellate mt genome. To obtain a large amount of information, we characterized 14 polymerase chain reaction (PCR) fragments of more than 27 kb of the mt genome of the toxic dinoflagellate Alexandrium catenella Whedon et Kofoid (Balech) using the cob and cox1 genes, the only identified functional mt genes of A. catenella excluding rRNA fragments. The mt PCR clones encode multiple copies of cytochrome b (cob) and cytochrome c oxidase subunit 1 (cox1) bearing several types of 5' or 3' sequences, and two rRNA fragments showing sequence similarity with a large subunit (LSU) rRNA D fragment and LSU RNA2 of apicomplexa. Each mt PCR clone showed different gene arrangements and intergenic sequences suggesting multiple contexts in the mt genome of A. catenella and frequent homologous recombinations. Reverse transcription PCR analysis suggested some types of the multiple copies of cob and cox1 genes are likely non-transcriptional. Further, A. catenella mt mRNAs lacked in-frame termination codons and a canonical initiation codon, excluding an 'atg' codon in cob mRNA. However, we successfully detected the activity of the electron transport proteins suggesting mt translation requires no canonical initiation and termination codons.

Morphological peculiarities of <i>Fragilidium mexicanum</i> Balech, 1988 (Dinophyta) from the Far-Eastern Seas of Russia	RUSSIAN JOURNAL OF MARINE BIOLOGY			English	Article						dinoflagellates; morphology; Fragilidium mexicanum; Fragilidium subglobosum; Fragilidium cysts; Sea of Japan; Sea of Okhotsk	DINOFLAGELLATE; CYSTS; COAST	The vegetative cells of Fragilidium mexicanum Balech are recorded from the Far Eastern seas of Russia (Sea of Japan and Sea of Okhotsk) for the first time. Morphological study of both cultured and wild cells of F. mexicanum showed that the shape of the cell and the first (1aEuro(3)) and second (2aEuro(3)) precingular plates, the direction of the slot in plate 1aEuro(3), and the shape of the anterior sulcul plate (S.a.) vary greatly. These features bear similarity to those of F. mexicanum, as well as a closely related species, F. subglobosum. The most conservative characters distinguishing the two species are the shape and size of the first and seventh postcingular plates and the shape of the posterior sulcal plate.	[Selina, M.

J	Blanco, EP; Lewis, J; Aldridge, J				Blanco, Eva Perez; Lewis, Jane; Aldridge, John			The germination characteristics of <i>Alexandrium minutum</i> (Dinophyceae), a toxic dinoflagellate from the Fal estuary (UK)	HARMFUL ALGAE			English	Article						Alexandrium; Cysts; Dinoflagellate; Excystment; Germination	GONYAULAX-TAMARENSIS; RESTING CYSTS; LIFE-CYCLE; SCRIPPSIELLA; EXCYSTMENT	The germination characteristics of Alexandrium minutum cysts from the Fal estuary were studied at different conditions of temperature (4-24 degrees C) and salinity (15-35 parts per thousand) and in the dark and low light intensity (2 mu mol(-2) s(-1)). Sediment sub-samples were directly cultured and processed at the end of the experiment for counts of non-germinated cysts. A decrease in the number of cysts was interpreted as germination that was calculated by comparison of the number of cysts over time with that of initial counts. The 50% germination time (time at which 50% of the total initial number of cysts had germinated) was calculated for each condition. A minutum did not germinate in the dark but it germinated under all other conditions studied. Highest germination occurred at salinities of 30 psu and 35 psu and temperatures from 8 degrees C to 24 degrees C (germination rate-expressed as the inverse of the 50% germination time: 1.1-1.2). Lowest germination occurred at 15 psu and 4 degrees C and 24 degrees C (germination rate: 3.9-3.8). However, little variation in germination rates occurred across the conditions studied. As these conditions represent those likely in the estuary it is probable that A. minutum cysts on the surface of the sediments represent a constant source of cells to the water column and sediment disturbance (revealing buried cysts) could rapidly inoculate the water column with vegetative cells. This data was used to develop a model for Alexandrium germination from coastal sediments. (C) 2008 Elsevier B.V. All rights reserved.

J	Persson, A; Smith, BC				Persson, Agneta; Smith, Barry C.			Grazing on a natural assemblage of ciliate and dinoflagellate cysts by the eastern oyster <i>Crassostrea virginica</i>	AQUATIC BIOLOGY			English	Article						Dinoflagellate; Cyst; Crassostrea virginica; Oyster; Grazing; Digesting	RESTING CYSTS; SCRIPPSIELLA-LACHRYMOSA; GLOBAL DIVERSITY; SEDIMENTS; GULF; GERMINATION; CILIOPHORA; MORPHOLOGY; DYNAMICS; PROTOZOA	A natural dinoflagellate- and ciliate-cyst community from anoxic sediment collected from New Haven, Long Island Sound, was concentrated with a particle sorter and fed to oysters Crassostrea virginica. The total number of cysts and the species composition of cysts in beakers containing live oysters were measured before and after feeding by the oysters. The oysters significantly reduced the numbers of both dinoflagellate and ciliate cysts. Both empty cyst walls and filled (live) cysts were consumed. The oysters decreased the number of total cysts to less than half compared to control beakers containing empty oyster shells. Results from the experiment show that natural assemblages of cysts in sediment are degraded by the feeding activities of oysters. If toxic cysts were present in natural sediments resuspended from the bottom, digestion of resting cysts could lead to toxin accumulation in oysters. There was no major shift in species composition of cysts; cysts known as fossilizable were destroyed, as well as cysts not known to be very resistant or preservable.

In a comparative approach, the 2 strains of A. tamarense, similar in their cellular paralytic shellfish toxin (PST) content, were selected because of their fundamentally different lytic potencies. The Alex2 strain clearly affected all target algae while the Alex5 strain had no negative effect on the growth of any of the target species during the study period, even though cell concentrations of Alex5 became very high (2 x 10(4) cells ml(-1)). As both strains contained comparable amounts of PST, this confirmed previous suggestions that so far unidentified compounds are causing the negative effects on other algae. Sensitivity of the tested algae to Alex2 differed considerably. The growth of some species was affected at very low Alex2 cell concentrations (< 10(2) cells ml(-1)), while the growth of other algae was not affected until cell concentrations exceeded 10(3) cells ml(-1). While a complete dieoff was the ultimate fate for almost all target species when grown in mixed culture with Alex2, Scrippsiella trochoidea formed temporary cysts, the number of which remained constant during the course of the experiment. The pH in the mixed cultures increased as the cultures grew dense. This had a substantial effect on Alex5 in the mixed cultures, in which Alex5 eventually died off because the target species have a higher tolerance to high pH. pH values did not determine the outcome of the experiments with Alex2 because the adverse effects of Alex2 on the growth of the other algae was evident before pH values became too high. Lytic extracellular compounds, which are produced by the large majority of A. tamarense strains tested so far, clearly have the potential to benefit this dinoflagellate by reducing competitor growth rates.

Quantitative real-time PCR was employed for detection and quantification of cells in natural sediments and of germinated vegetative cells in the water column. Temperature, salinity, and dissolved nutrient concentrations were examined in field mesocosm experiments to identify physicochemical factors associated with germination, while the effects of temperature and light on germination were examined in laboratory experiments. We detected and monitored a wide range of cyst abundances of H. akashiwo (from 164 to 2820 cysts cm 3 wet sediment) and C. subsalsa cysts (from 2 to 135 Cysts cm(-3) wet sediment) in environmental sediments. Germinated H. akashiwo cells were detected in situ after temperatures reached 15 degrees C. However, in laboratory studies, H. akashiwo germination occurred at even lower temperatures (10 degrees C), which was considerably lower than typical germination temperatures from similar Japanese strains. In contrast, a temperature of 20 degrees C stimulated C. subsalsa germination in both field and laboratory studies, although germination still occurred at low temperatures (10 degrees C). The presence or absence of light did not affect the germination of C. subsalsa. The low quantities of detected vegetative cells from cyst germination for both H. akashiwo and C. subsalsa suggest the inoculation of a small number of vegetative cells into the water column during the spring and early summer months.

Historical records of coastal eutrophication-induced hypoxia	BIOGEOSCIENCES			English	Review							SEA BENTHIC FORAMINIFERA; GULF-OF-MEXICO; WALLED DINOFLAGELLATE CYSTS; OXYGEN MINIMUM ZONE; SANTA-BARBARA BASIN; ORGANIC-CARBON FLUX; CENTRAL BALTIC SEA; LONG-TERM CHANGES; CHESAPEAKE BAY; MISSISSIPPI RIVER	Under certain conditions, sediment cores from coastal settings subject to hypoxia can yield records of environmental changes over time scales ranging from decades to millennia, sometimes with a resolution of as little as a few years. A variety of biological and geochemical indicators (proxies) derived from such cores have been used to reconstruct the development of eutrophication and hypoxic conditions over time. Those based on (1) the preserved remains of benthic organisms (mainly foraminiferans and ostracods), (2) sedimentary features (e.g. laminations) and (3) sediment chemistry and mineralogy (e.g. presence of sulphides and redox-sensitive trace elements) reflect conditions at or close to the seafloor. Those based on (4) the preserved remains of planktonic organisms (mainly diatoms and dinoflagellates), (5) pigments and lipid biomarkers derived from prokaryotes and eukaryotes and (6) organic C, N and their stable isotope ratios reflect conditions in the water column. However, the interpretation of these indicators is not straightforward. A central difficulty concerns the fact that hypoxia is strongly correlated with, and often induced by, organic enrichment caused by eutrophication, making it difficult to separate the effects of these phenomena in sediment records. The problem is compounded by the enhanced preservation in anoxic and hypoxic sediments of organic microfossils and biomarkers indicating eutrophication. The use of hypoxia-specific proxies, such as the trace metals molybdenum and rhenium and the bacterial biomarker isorenieratene, together with multi-proxy approaches, may provide a way forward. All proxies of bottom-water hypoxia are basically qualitative; their quantification presents a major challenge to which there is currently no satisfactory solution. Finally, it is important to separate the effects of natural ecosystem variability from anthropogenic effects. Despite these problems, in the absence of historical data for dissolved oxygen concentrations, the analysis of sediment cores can provide plausible reconstructions of the temporal development of human-induced hypoxia, and associated eutrophication, in vulnerable coastal environments.

J	Tardio, M; Ellegaard, M; Lundholm, N; Sangiorgi, F; Di Giuseppe, G				Tardio, Massimiliano; Ellegaard, Marianne; Lundholm, Nina; Sangiorgi, Francesca; Di Giuseppe, Graziano			A hypocystal archeopyle in a freshwater dinoflagellate from the Peridinium umbonatum group (Dinophyceae) from Lake Nero di Cornisello, South Eastern Alps, Italy	EUROPEAN JOURNAL OF PHYCOLOGY			English	Article						cyst; dinoflagellate; hypocystal archeopyle; lakes; Peridinium inconspicuum; Peridinium umbonatum; South Eastern Alps	SEXUAL REPRODUCTION; CYST FORMATION; PHYLOGENY; STEIN	This study presents the first record of a living dinoflagellate cyst with a hypocystal, antapical archeopyle. It is also the first detailed account of the archeopyle of a living freshwater cyst from the genus Peridinium. The cysts were isolated from sediment traps deployed in Lake Nero di Cornisello, a low-alkalinity high mountain lake of the Adamello mountain range (2233 m above sea level, South Eastern Alps, Italy). The archeopyle is large, clearly hypocystal, polygonal, and slightly peanut-shaped. The species producing this cyst belongs to the Peridinium umbonatum group and is described based on scanning electron microscopy and light microscopy. Partial sequences of SSU rDNA were obtained and compared with previously published sequences from the P. umbonatum group. The taxonomic position of the species is discussed.

GERMINATION OF RESTING STAGES OF DIATOMS AND DINOFLAGELLATES IN MARINE SEDIMENTS FROM TWO UPWELLING AREAS OF CHILE	GAYANA BOTANICA			Spanish	Article						Diatoms; dinoflagellates; resting stages; cultures; sediments; Chile	NORTHERN BALTIC SEA; FRAGILARIOID DIATOMS; BACILLARIOPHYCEAE; VARIABILITY; SURVIVAL; PRODUCTIVITY; SPORES; WATERS; OXYGEN; EXPORT	With the aim to assess germination of diatom and dinoflagellates resting spores we Cultured under laboratory conditions surface sediments collected in the Mejillones Bay (23 degrees S) and off Concepcion (36 degrees S), Chile. These sediments were cultured in the laboratory with a 12:12 h L/D cycle, light intensity of 140 mu mol m(2) s(-1), at room temperature, and with a salinity of 35.4 units. The main diatom species in the sediments were Skeletonema japonicum and Chaetoceros spores. Dinoflagellate cysts were represented by the genera Diplopsalis, Scrippsiella, and Woloszynskia and the species Protoperidinium avellanum and P. leonis. After 20 days of culturing, germination and growth was recorded for S. japonicum and several of the Chaetoceros species, although their abundance was low. The diatoms with abundant growth were Stauroneis legleri, Pseudostaurosira trainorii, Pseudostaurosira sp. 1, Pseudostaurosira sp. 2, and Navicula pseudoreinhardtii. The dinoflagellate Woloszynskia sp. also germinated and grew abundantly in the culture. This study includes a brief description of the cultured species and some aspects of their ecology. In addition, we discuss the possible causes for low levels of germination in planktonic diatoms, finding low dissolved oxygen concentrations in the bottom waters to be one of the main factors that presumably affected the survival of resting spores in the sediment.

This paper reports exceptionally high cell concentrations (10(5) to 10(6) cells L-1) of the species found during bioluminescent blooms in 2003 and 2004 in a shallow embayment of the Aland archipelago at the SW coast of Finland. Clonal cultures were established for morphological, molecular, toxicological and ecophysiological investigations to characterize the Finnish populations and compare them to other global A. ostenfeldii isolates. The Finnish isolates exhibited typical morphological features of A. ostenfeldii such as large size, a prominent ventral pore and an orthogonally bent first apical plate. However, unambiguous differentiation from closely related Alexandrium peruvianum was difficult due to considerable variation of sulcal anterior plate shapes. The Finnish strains were genetically distinct from other isolates of the species, but phylogenetic analyses revealed a close relationship to isolates from southern England and an A. peruvianum morphotype from the Spanish Mediterranean. Together these isolates formed a distinct clade which was separated from a clade containing other Northern European, North American and New Zealand populations. Toxin analyses confirmed the presence of the PSP toxins GTX2, GTX3 and STX in both Finnish isolates with GTX3 being the dominant toxin. Total relative PSP toxin contents were moderate, ranging from approximately 6 to 15 fmol cell(-1) at local salinities of 5 and 10 psu, respectively. Spirolides were not detected. Salinity tolerance experiments showed that the Finnish isolates were well adapted to grow at the low salinities of the Baltic Sea. With a salinity range of approximately 6 to 2025 psu, Baltic populations are physiologically distinct from their marine relatives. Vigorous production of different cyst types in the cultures suggest that cysts may play a crucial role in the survival and retainment of A. ostenfeldii populations in the Baltic Sea.

Wayne			Sexual and Asexual Processes in <i>Protoperidinium steidingerae</i> Balech (Dinophyceae), with Observations on Life-History Stages of <i>Protoperidinium depressum</i> (Bailey) Balech (Dinophyceae)	JOURNAL OF EUKARYOTIC MICROBIOLOGY			English	Article						Eleutheroschisis; gamete; heterotrophic dinoflagellate; hypnozygote; nuclear cyclosis; planomeiocyte; planozygote	HETEROTROPHIC DINOFLAGELLATE; GRAZING RATES; GROWTH; REPRODUCTION; PHYLOGENY; CYCLE; RDNA	A suite of morphological, histological, and molecular techniques was used to reveal for the first time division, sexuality, mandatory dormancy period of hypnozygotes, and identity of life-history stages of any Protoperidinium spp. In both Protoperidinium steidingerae and Protoperidinium depressum, asexual division occurred by eleutheroschisis within a temporary cyst, yielding two daughter cells. Daughter cells were initially round and one-half to two-thirds the size of parent cells then rapidly increased in size, forming horns before separating. Gamete production and fusion was constitutive in clonal and non-clonal cultures, indicating that both species may be homothallic. Gametes were isogamous, approximately half the size and lacking the pink pigmentation of the vegetative cells, and were never observed to feed. Gamete fusion resulted in a planozygote with two longitudinal flagella. Planozygotes of P. steidingerae formed hypnozygotes. The fate of planozygotes of P. depressum is unknown. Hypnozygotes of P. steidingerae had a mandatory dormancy period of ca. 70 days. Germination resulted in planomeiocytes with two longitudinal flagella. Nuclear cyclosis occurred in the planozygotes of P. depressum, but in the planomeiocytes of P. steidingerae. The plate tabulation and gross morphology of gametes of P. steidingerae and P. depressum differed markedly from those of vegetative cells. Thus, misidentification of morphologically distinct life-history stages and incomplete examination of thecal plate morphology in field specimens has likely led to taxonomic confusion of Protoperidinium spp. in previous studies.

Seasonal and interannual variation in the phytoplankton community in the north east of Scotland	JOURNAL OF SEA RESEARCH			English	Article; Proceedings Paper	Workshop on Time Series Data Relevant to Eutrophication and Ecological Quality Indicators	SEP 11-14, 2006	Tisvildeleje, DENMARK			Time series; Phytoplankton; Diatoms; Dinoflagellates; Spring bloom; Chaetoceros; Skeletonema	NE ATLANTIC-OCEAN; NARRAGANSETT BAY; CLIMATE-CHANGE; RESTING STAGES; SEA WATER; LONG-TERM; VARIABILITY; PATTERNS; DIATOM; ECOSYSTEMS	In 1997 a monitoring site was established 5 km offshore from Stonehaven (56 degrees 57.8' N, 02 degrees 06.2'W) in the north east of Scotland to examine the effects of physical and chemical parameters on the plankton community in this region. Analysis of the first 10 years of data show that, in common with trends in the NE Atlantic, there was an increasing trend in temperature and salinity at the site. Nutrients were typical of unimpacted waters in this region, with nitrate being the main limiting nutrient over the summer months. The phytoplankton community composition showed strong seasonality with low phytoplankton biomass in the winter, diatoms dominating in spring and early summer and dinoflagellates appearing in mid to late summer. Two different regimes were recognised: from 1997-2000 and 2005-2006, where the chlorophyll concentration peaked in the early part of the year (mid month values ranging from 2.6-4.1 mu l(-1)) and a period from 2001-2004 where chlorophyll mid month values did not exceed 2.5 mu g l(-1). A decreasing trend in the abundance of dinoflagellates, including members of the genus Ceratium, was observed from 2003-2006. In addition, from 1997-2001, the diatom genus Chaetoceros was the dominant species in the spring bloom, but post 2001 Skeletonema spp. became more abundant. The study highlights the variability that exists in time series data and emphasises the need for long term time series to determine the long term trends and impacts of the phytoplankton community on the marine ecosystem.

There is a dearth of the multi-decadal time series data from plankton needed to document eutrophication. and the cysts may provide an alternative source of information. Two different eutrophication signals have been described so far from cyst records: 1) from the Oslofjord, comprising a marked increase in total cyst concentrations (interpreted as probably reflecting increased phytoplankton productivity). with Lingulodinium polyedrum cysts accounting for most of the increase (interpreted as a species particularly benefiting from added nutrients from cultural eutrophication in late summer when nutrients otherwise may be limiting); and 2) the heterotroph signal, from several other Norwegian fjords and Tokyo Bay, Japan, involving both cases of increased cyst concentrations and others with no particular increase, but with a marked proportional increase in cysts of heterotrophic species (interpreted as reflecting increased diatoms and possibly other prey for the heterotrophic dinoflagellates and/or more unfavourable conditions for autotrophs, e.g. from shading). These signals should be used critically, and there is a particular need to distinguish between eutrophication signals and climate signals that may be co-occurring at a given time. Work by various authors has generally supported the concept of these cyst-based signals since they were first published, including both further records from cored sediments from other parts of the world and studies relating cyst distributions in surface sediments to gradients of pollution and nutrients from sewage discharge. Recent, unpublished work by Dale and Saetre, linked cyst signals in cored sediments to the timing of collapse of local fisheries at different times within the past fifty years in four fjord systems along the Norwegian Skagerrak coast (supporting earlier postulations by fisheries biologists that eutrophication was a possible cause). They also link these local eutrophication events to regional variation in the NAO, thought to have caused pulses of nutrient loading within the Skagerrak from increased transport of relatively nutrient rich North Sea water into the system. This may represent a major breakthrough in understanding the relationship between climatic variation and coastal eutrophication. Some concluding remarks are added in an attempt to show how these cyst signals: 1) suggest interesting comparisons with the ecological classification of bloom dinoflagellates by Smayda and Reynolds [Smayda, T.J., Reynolds, C.S., 2003. Strategies of marine dinoflagellate survival and some rules of assembly. J. Sea Res. 49, 95-106.]: and 2) have helped to identify important questions regarding the extent to which climate variation influences coastal eutrophication. Addressing these questions represents an urgent challenge to marine science. (C) 2008 Elsevier B.V. All rights reserved.

They can be divided into five major assemblage types, the distribution of which can clearly be linked to the overlying water masses. Notably, a very clear distinction between sites influenced by Atlantic water and Arctic water, respectively, is seen in the change in dominance from O. centrocarpum s.l. to I. minutum and is strongly related to sea-surface temperature. More subtle hydrographical features are also recorded in the assemblages, as can be seen from the spatially coherent distribution of the Atlantic assemblages, which allows discrimination between the Norwegian Coastal Current zone, the Norwegian Atlantic Current zone and two regions of modified Norwegian Atlantic Current waters. Here sea-surface temperature does not seem to be the primary parameter controlling the distribution of the assemblages. Multivariate analyses suggest that the assemblages are associated with the stratification and productivity annual cycles. Cysts of P. dalei seem to favour stratified environments, while O. centrocarpum s.l. might be more adapted to unstable conditions. Cysts of P dalei are also associated with early spring stratification and productivity, whereas other species such as S. ramosus are related to late spring/summer productivity and stratification.

Svalbard is an important locality representing the distal influence of an attenuated North Atlantic Current, and crucial to the understanding of the thermohaline circulation in the North Atlantic. The study presents the first modern report of dinoflagellate cysts from this region making use of many recent taxonomic advances. Dinocysts are associated with waters of particular abiotic and biotic properties (temperature, salinity and nutrient content). On the basis of the dinocyst assemblages recovered from the sediments, several surface water types are recognized including those influenced by warm, saline Atlantic Water (AW) and those, where such influence is restricted.

The cysts are spherical and pale brown in color. The cyst wall has two layers: a thick endophragm with granulate surface, and a thin periphragm. Three complete and incomplete parasutures appear on the surface of the endocyst. The archeopyle formed on the endocyst is basically saphopylic and compound with some combination of complete and incomplete parasutures. The cyst of Protoperidinium parthenopes closely resembles the cyst of Protoperidinium americanum (Gran & Braarud 1935) Balech 1974, but differs in the shape of the periphragm, the cyst diameter, and in the archeopyle.

This paper examines whether photosynthetic algal and bacterial pigments stored in the lake sediment can be used to identify different lake typologies and population dynamics of primary producers. We focus on a multivariate numerical analysis relating the relative abundance of marker pigments of algae, cyanobacteria and phototrophic sulphur bacteria to a set of physical and chemical factors (both natural and anthropogenic) determining the environmental conditions in mountain lakes. Redundancy Analysis (RDA), including partial RDA, of carotenoid assemblages constrained by environmental variables suggests that the main differences between lake districts are caused by geographic position (e.g. longitude), catchment characteristics (e.g. % carbonate rocks) and chemical variables (e.g. Mg, NO3). Other variables such as temperature and phosphorus play a minor role, probably because of the short length of the gradient covered by these cold and mostly oligotrophic lakes. Pigment composition varies primarily in response to catchment geology and pollution (i.e. acidification from long range transport) gradients. Purple sulphur photosynthetic bacteria (okenone) and cyanobacteria (echinenone, canthaxanthin, scytonemin) are replaced by siliceous algae (fucoxanthin and diatoxanthin), cryptophytes (alloxanthin) and dinoflagellates (diadinoxanthin). With respect to site classification, the pigment ordination shows a clear distinction between the more pristine lakes (in the Pyrenees) and the more polluted sites (in the Tatra Mountains and Central Southern Alps) or those with water higher in solute content (the Julian Alps and Greenland).

Pico- and nanoalgae were counted by flow cytometry whereas photosynthetic and heterotrophic protists >= 4 mu m were identified and counted by inverted microscopy. Protists were always present in sea ice and surface water samples throughout the study period. The most abundant protists in sea ice and surface waters were cells <4 mu m. They were less abundant in sea ice (418-3051 x 10(3) cells L(-1)) than in surface waters (1393-5373 x 10(3) cells L(-1)). In contrast, larger protists (>= 4 mu m) were more abundant in sea ice (59-821 x 10(3) cells L(-1)) than in surface waters (22-256 x 10(3) cells L(-1)). These results suggest a selective incorporation of larger cells into sea ice. The >= 4 mu m protist assemblage was composed of a total number of 73 taxa, including 12 centric diatom species, 7 pennate diatoms, 11 dinoflagellates and 16 flagellates. The taxonomic composition in the early stage of ice formation (i.e., new ice) was very similar to that observed in surface waters and was composed of a mixed population of nanoflagellates (Prasinophyceae and Prymnesiophyceae), diatoms (mainly Chaetoceros species) and dinoflagellates. In older stages of sea ice (i.e., young ice and thin first-year ice), the taxonomic composition became markedly different from that of the surface waters. These older ice samples contained relatively fewer Prasinophyceae and more unidentified nanoflagellates than the younger ice. Diatom resting spores and dinoflagellate cysts were generally more abundant in sea ice than in surface waters. However, further studies are needed to determine the importance of this winter survival strategy in Arctic sea ice. This study clearly shows the selective incorporation of large cells (>= 4 mu m) in newly formed sea ice and the change in the taxonomic composition of protists between sea ice and surface waters as the fall season progresses.

Cupric glutamate had an excellent ability to inhibit the growth of Alexandrium sp. LC3, but the inhibition efficiency did not increase with higher cupric glutamate concentration. The studies on the inhibition ofAlexandrium sp. LC3 by cupric sulfate or cupric glutamate showed that cupric glutamate had a higher inhibition rate than cupric sulfate (P < 0.05). HDTMAB could significantly enhance the inhibition by cupric glutamate (P < 0.05). Ultrastructural changes of Alexandrium sp. LC3 under cupric sulfate, cupric glutamate, and cupric glutamate-HDTMAB combined treatment were studied with TEM. Under these stresses, the integrity of the cell plasma membranes (cell plasma membrane, chloroplast and mitochondria membranes) was destroyed. The degree of damage under cupric glutamate-HDTMAB combined treatment was more severe than under the other stresses. These results indicated that mechanistically cupric glutamate inhibits algal growth by destroying the cell membranes, and that HDTMAB promotes this process, which induced mass extravasation of intracellular components and more copper ion entry into the plasma.

J	Escalera, L; Reguera, B				Escalera, Laura; Reguera, Beatriz			PLANOZYGOTE DIVISION AND OTHER OBSERVATIONS ON THE SEXUAL CYCLE OF SEVERAL SPECIES OF <i>DINOPHYSIS</i> (DINOPHYCEAE, DINOPHYSIALES)	JOURNAL OF PHYCOLOGY			English	Article						Dinophysis; harmful algal blooms; planozygote division; sexual cycle	LIFE-CYCLE; DINOFLAGELLATE; CULTURE; REPRODUCTION; ACUMINATA	A life-cycle model has been proposed for Dinophysis, but several transitions between stages of this cycle needed more detailed description. In this study, the steps from mating gamete pairs, cell fusion, nuclear fusion, and the fate of planozygotes were tracked and described from incubations of different sexual-cycle stages of D. acuminata Clap. et J. Lachm., D. cf. ovum F. Schutt, and D. acuta Ehrenb. There were several pathways for depauperating division and formation of small and intermediate cells; observed mating tubes that connect mating gamete pairs were more delicate than the feeding tube described in D. acuminata; nuclear fusion occurs following cell fusion. Planozygotes were able to divide and produce several vegetative cells 2-3 weeks after incubation. New pathways were added to the revised sexual life-cycle model of Dinophysis spp. It is hypothesized that planozygotes are the main diploid sexual stage that may be involved in overwintering and seeding strategies. The importance of planozygote division, without further maturation into a resting cyst, as an adaptive strategy for holoplanktonic organisms is discussed.

The new species appeared during spring with densities up to 1.48 x 10(7) cells L(-1) in some tributaries and gullies of Three Gorge Reservoir and Lake Donghu, China, forming red tides. Peridiniopsis niei is a cyst-producing freshwater dinoflagellate that belongs to the group Penardii. The plate tabulation is po+x+4 '+0a+6 ''+5c+5s+5 '''+2 '''' and the plate pattern is symmetric. The cells of P. niei are pentagonal in ventral view, the epitheca is larger than the hypotheca, making up about 2/3 the length of the cell. Plate 3 ' is hexangular. The closest species to P. niei is P. penardii (Lemmermann) Bourrelly, but cells of the former are pentagonal, very compressed dorsoventrally, and the hypotheca is truncated with one transparent, robust spine on each antapical plate.

This species is morphologically, behaviourally, and genetically (18S rDNA sequence) different from Parvilucifera infectans, until now the only species of the genus Parvilucifera to be genetically analyzed. Sequence analysis of the 18S ribosomal DNA supported P. sinerae as a new species placed within the Perkinsozoa and close to P. infectans. Data on the seasonal occurrence of P. sinerae, its infective rates in natural and laboratory cultures, and intra-species strain-specific resistance are presented. Life-cycle studies in field samples showed that the dinoflagellate resting zygote (resting cyst) was resistant to infection, but the mobile zygote (planozygote) or pellicle stage (temporary cyst) became infected. The effects of light and salinity levels on the growth of P. sinerae were examined, and the results showed that low salinity levels promote both sporangial germination and higher rates of infection. Our findings on this newly described parasite point to a complex host-parasite interaction and provide valuable information that leads to a reconsideration of the biological strategy to control dinoflagellate blooms by means of intentional parasitic infections.

Oxygen profiles at the sediment-water interface and inorganic nutrients in the near bottom water were determined once a week. In the additions of P. taeniata and W halophila the sediment quickly became anoxic. and subsequently there was a flux of > 1 mmol PO43- m(-2) d(-1) out of the sediment in these treatments. The majority of the released P came from P stored in the sediment and not from the organic phosphorus added. The result was very different for the S. hangoei addition. This species underwent a life cycle change to form temporary cysts. During this process there was a net uptake of nutrients. After the formation of cysts the concentration of inorganic nutrient was similar to that of the control. Cysts generally survive for long periods in the sediment (months to years) before germinating, but can also be permanently buried in the sediment. The novel idea presented here is that the phytoplankton composition may directly affect sediment processes such as oxygen consumption and phosphorus release, through species-specific life cycle changes and yields of resting stages produced prior to sedimentation. This can be an important aspect of nutrient cycling in eutrophic waters, like the Baltic Sea, where there is large year-to-year difference in the amount of resting stages settling at the sea floor, mainly due to differences in abundance of diatoms and dinoflagellates during the spring bloom. If yields of resting stages change, e.g. due to changes in the phytoplankton community, it may lead to alterations in the biogeochemical cycling of nutrients. (C) 2008 Elsevier Ltd.

A total of 24 cyst types were recorded, of which 12 and five were identified at the species and genus levels, respectively. Dinoflagellate cysts were recorded from all sampling sites, but they differed in total abundance (15-270 cysts ml(-1)) and diversity index (H' 0.88-2.40). Heterotrophic dinoflagellate cysts assigned to heterotrophic species were the most abundant trophic form, with 418 cysts ml(-1), representing 55% of the total cyst abundance. Cluster analysis based on the abundance of dinoflagellate cyst species indicated that sampling sites were segregated into three groups likely to be related to the proportion of autotrophic vs. heterotrophic species cysts and the total abundance of cysts at each site. Distinctive cyst species composition differences among sampling sites may allow inferences about local nutrient and feeding dynamics within the water column.

Six morphospecies were characterised: A. tamarense, A. minutum, A. ostenfeldii, A. peruvianum, A tamutum and A andersoni. Both PSP toxin producing and nontoxic strains of A. tamarense and A. minutum were observed. The average toxicities of toxic strains for both cultured species were respectively 11.3 (8.6 S.D.) and 2.3 (0.5 S.D.) pg STX equiv. cell(-1). Alexandrium ostenfeldii and A. peruvianum did not synthesise PSP toxins but HPLC-MS analysis of two strains showed distinct spirolide profiles. A cyst-derived culture of A. peruvianum from Lough Swilly mainly produced spirolides 13 desmethyl-C and 13 desmethyl-D whereas one of A. ostenfeldii, from Bantry Bay, produced spirolides C and D. Species identification was confirmed through the analyses of SSU, ITS1-5.8S-ITS2 and LSU rDNA genes. Some nucleotide variability was observed among clones of toxic strains of A. tamarense, which all clustered within the North American clade. However, rDNA sequencing did not allow discrimination between the toxic and non-toxic forms of A. minutum. Phylogenetic analysis also permitted the differentiation of A. ostenfeldii from A. peruvianum. Resting cysts of PSP toxin producing Alexandrium species were found in Cork Harbour and Belfast Lough, locations where shellfish contamination events have occurred in the past, highlighting the potential for the initiation of harmful blooms from cyst beds. The finding of supposedly non-toxic and biotoxin-producing Alexandrium species near aquaculture production sites will necessitate the use of reliable discriminative methods in phytoplankton monitoring.

Dinoflagellate blooms in stratified waters, vertical migration of vegetative cells, and the accumulation of populations within thin layers are well-documented phenomena in nature. We propose a conceptual model that places these phenomena in a functional, ecological context: vegetative cells of a dinoflagellate population display vertical migration, but at the end of the bloom, environmental or internal cues shift the cell cycle to gamete formation. Then the vertical migrations cease, and cells accumulate in a layer at the pycnocline where gametes fuse to form zygotes, which then sink to the sediment as resting cysts. We support this conceptual model with experimental and environmental evidence. (C) 2008 Elsevier B.V. All rights reserved.

Debora			Microsatellite genotyping of single cells of the dinoflagellate species <i>Lingulodinium polyedrum</i> (Dinophyceae):: A novel approach for marine microbial population genetic studies	JOURNAL OF PHYCOLOGY			English	Article						dinoflagellate; genetic diversity; Lingulodinium polyedrum; microsatellites; phytoplankton; single-cell PCR	PCR AMPLIFICATION; SPRING BLOOM; GENOME SIZE; MARKERS; DIVERSITY; DNA; CYSTS; LOCI; DIFFERENTIATION; EXTRACTION	In recent years, two new approaches have been introduced in genetic studies of phytoplankton species. One is the application of highly polymorphic microsatellite markers, which allow detailed population genetic studies; the other is the development of methods that enable the direct genetic characterization of single cells as an alternative to clonal cultures. The aim of this study was to combine these two approaches in a method that would allow microsatellite genotyping of single phytoplankton cells, providing a novel tool for high-resolution population genetic studies. The dinoflagellate species Lingulodinium polyedrum (F. Stein) J. D. Dodge was selected as a model organism to develop this novel approach. The method we describe here is based on several key developments: (i) a simple and efficient DNA extraction method for single cells, (ii) the characterization of microsatellite markers for L. polyedrum, (iii) a protocol for the species identification of single cells through the analysis of partial rRNA gene sequences, and (iv) a two-step multiplex PCR protocol for the simultaneous amplification of microsatellite markers and partial rRNA gene sequences from single cells. Our protocol allowed the amplification of up to six microsatellite loci together with either the complete ITS1-5.8S-ITS2 region or a partial 18S region of the ribosomal gene of L. polyedrum from single motile cells and resting cysts. This article describes and evaluates the developed approach and discusses its significance for population genetic studies of L. polyedrum and other phytoplankton species.

J	González, C; Dupont, LM; Mertens, K; Wefer, G				Gonzalez, Catalina; Dupont, Lydie M.; Mertens, Kenneth; Wefer, Gerold			Reconstructing marine productivity of the Cariaco Basin during marine isotope stages 3 and 4 using organic-walled dinoflagellate cysts	PALEOCEANOGRAPHY			English	Article							INTERTROPICAL CONVERGENCE ZONE; RAPID CLIMATE CHANGES; NORTH-ATLANTIC; TROPICAL ATLANTIC; VEGETATION RESPONSE; SURFACE SEDIMENTS; CARIBBEAN SEA; EL-NINO; VARIABILITY; CYCLE	An organic-walled dinoflagellate cyst analysis was carried out on sediment core MD03-2622, retrieved from the Cariaco Basin. The core comprises the 73-30 ka interval. Down core changes in cyst abundance, accumulation rate, and composition of cyst assemblages were used to identify climatic and oceanographic changes at orbital and millennial time scales in this near-equatorial seasonal upwelling area. Throughout the sequence, dinoflagellate cyst assemblages were dominated by heterotrophic dinocysts (mainly Brigantedinium spp.), with the exception of four autotrophic-dominated (mainly Spiniferites ramosus) intervals around 58, 53, 46, and 37 ka. At orbital time scales, changes in the dinoflagellate productivity seem to follow low-latitude insolation, with the highest productivities coinciding with maximum February insolation (47-38 ka). At millennial scales, cyst accumulation rates appeared to coincide with Dansgaard-Oeschger (D-O) variability, with significant increments occurring during warm interstadials. The opposite was true during stadials. Short periods of high nutrient availability and stratified conditions followed Heinrich events H4, H5, H5a, and H6 and concurred with enhanced river runoff. Spectral analyses confirm the existence of these and other higher-frequency periodicities and support the idea of a tightly coupled terrestrial/marine and tropical/high-latitude climate system during the last glacial period.

During the life cycle of this species, two kinds of cysts are produced: resting cysts, which are long-lasting and double-walled, and temporary cysts, which are short-lasting and thin-walled. In addition, short-lasting, but resting-like cysts can also be formed. Although it is crucial to identify sexual events in a dinoflagellate population, sexual and asexual cysts are morphologically very similar in this species. Therefore, we studied the complete life cycle and the nature of the cyst-like stages formed after individual isolation of specimens and crossing of clonal cultures established from germination of wild resting cysts. Asexual division in A. peruvianum takes place either in the motile stage by sharing of the theca (desmoschisis), or inside a vegetative cyst (temporary cyst), from which two, or at times four or six naked daughter cells can originate. The daughter cells completely synthesize new cell walls (eleutheroschisis). Sexuality was confirmed by the presence of fusing gamete pairs and longitudinally biflagellated planozygotes after out-crossing of compatible clonal strains. However, the clonal cultures had low levels of self-compatibility, since a flow cytometry analysis showed that synchronized self-crosses produced few zygotes (< 5%). After isolation of individual cells, it was proved that the fate of the planozygotes depended on the nutritional status of the isolation media. Most of the planozygotes isolated to replete medium (L1) divided, whereas in medium lacking nitrates (L-N) or phosphates (L-P) they formed temporary, thin-walled cysts. Temporary cysts formed in L1 were always uninucleated and gave rise to one cell, while those formed in L-N or L-P produced 1-6 small cells. In addition, resting cysts were formed in culture, but never after individual planozygote isolation. Resting cysts were uninucleated and needed maturation time before entering dormancy. The resting cysts were considered sexual products, since longitudinally biflagellate germlings were liberated after germination in all cases studied. Mature resting cysts (52.3 +/- 3.0 mu m) had a dormancy period of 1-3 months, whereas temporary asexual cysts (32.5 +/- 5.4 mu m) germinated in less than 7 days. (c) 2008 Elsevier B.V.

Comparative analysis of two algicidal bacteria active against the red tide dinoflagellate <i>Karenia brevis</i>	HARMFUL ALGAE			English	Article						algicidal bacteria; cyst formation; Cytophaga; dinoflagellate; Flavobacteriaceae; harmful algal bloom; Karenia brevis	MARINE BACTERIUM; FAMILY FLAVOBACTERIACEAE; HARMFUL MICROALGAE; GYMNODINIUM-BREVE; SP-NOV.; GROWTH; SEA; JAPAN; PHYTOPLANKTON; COMMUNITIES	The red tide dinoflagellate Karenia brevis blooms annually along the eastern Gulf of Mexico, USA, and is often linked to significant economic losses through massive fish kills, shellfish harvest closures, and the potential threat to humans of neurotoxic shellfish poisonings as well as exposure to aerosolized toxin. As part of an effort to enhance the strategies employed to manage and mitigate these events and their adverse effects, several approaches are being investigated for controlling blooms. Previous studies have established the presence of algicidal bacteria lethal to K. brevis in these waters, and we aim to characterize bacterial-algal interactions, evaluate their role as natural regulators of K. brevis blooms, and ultimately assess possible management applications. Herein, the algicidal activity of a newly isolated Cytophaga/Flavobacterium/Bacteroidetes (CFB)-bacterium, strain S03, and a previously described CFB-bacterium, strain 41-DBG2, was evaluated against various harmful algal bloom (HAB) and non-HAB species (23 total), including multiple clones of K. brevis, to evaluate algal target specificity. Strains S03 and 41-DBG2, which employ direct and indirect modes of algicidal lysis, respectively, killed similar to 20% and similar to 40% of the bacteria-containing isolates tested. Interestingly, no bacteria-free algal cultures were resistant to algicidal attack, whereas susceptibility varied occasionally among bacteria-containing isolates of a single algal taxon originating from either the same or different geographic location. The dynamics of K. brevis culture death appeared to differ according to whether the algicidal bacterium did or did not require direct contact with algal cells, with the former most rapidly affecting K. brevis morphology and causing cell lysis. Both bacterial strains promoted the formation of a small number of cyst-like structures in the K. brevis cultures, possibly analogous to temporary cysts formed by other dinoflagellates exposed to certain types of stress. Results were also consistent with earlier work demonstrating that bacterial assemblages from certain cultures can confer resistance to attack by algicidal bacteria, again indicating the complexity and importance of microbial interactions, and the need to consider carefully the potential for using such bacteria in management activities.

This is the first report of the auxosporulation by T. australis in situ. Resting spores were also observed in the sediment even before new spore formation, suggesting that T. australis can overwinter in the sediment. Heterotrophic dinoflagellates ingested and digested vegetative cells and auxospores but did not digest resting spores, suggesting a high tolerance of resting spores to grazing by heterotrophic dinoflagellates. We discuss the possible life history and overwintering strategy that T. australis uses in an Antarctic coastal area to cope with the unpredictable timing of sea ice growth and decay.

Historic 2005 toxic bloom of <i>Alexandrium fundyense</i> in the western Gulf of Maine:: 2.: Coupled biophysical numerical modeling	JOURNAL OF GEOPHYSICAL RESEARCH-OCEANS			English	Article							PHYSICAL-BIOLOGICAL MODEL; RED TIDE DINOFLAGELLATE; VERTICAL MIGRATION; HUMIC SUBSTANCES; OCEANIC MODEL; CIRCULATION; SURFACE; POPULATIONS; MECHANISMS; COORDINATE	A coupled physical/biological modeling system was used to hindcast a massive Alexandrium fundyense bloom that occurred in the western Gulf of Maine in 2005 and to investigate the relative importance of factors governing the bloom's initiation and development. The coupled system consists of a state-of-the-art, free-surface primitive equation Regional Ocean Modeling System (ROMS) tailored for the Gulf of Maine (GOM) using a multinested configuration, and a population dynamics model for A. fundyense. The system was forced by realistic momentum and buoyancy fluxes, tides, river runoff, observed A. fundyense benthic cyst abundance, and climatological nutrient fields. Extensive comparisons were made between simulated ( both physical and biological) fields and in situ observations, revealing that the hindcast model is capable of reproducing the temporal evolution and spatial distribution of the 2005 bloom. Sensitivity experiments were then performed to distinguish the roles of three major factors hypothesized to contribute to the bloom: (1) the high abundance of cysts in western GOM sediments; (2) strong ` northeaster' storms with prevailing downwelling- favorable winds; and (3) a large amount of fresh water input due to abundant rainfall and heavy snowmelt. Model results suggest the following. (1) The high abundance of cysts in western GOM was the primary factor of the 2005 bloom. (2) Wind- forcing was an important regulator, as episodic bursts of northeast winds caused onshore advection of offshore populations. These downwelling favorable winds accelerated the alongshore flow, resulting in transport of high cell concentrations into Massachusetts Bay. A large regional bloom would still have happened, however, even with normal or typical winds for that period. (3) Anomalously high river runoff in 2005 resulted in stronger buoyant plumes/currents, which facilitated the transport of cell population to the western GOM. While affecting nearshore cell abundance in Massachusetts Bay, the buoyant plumes were confined near to the coast, and had limited impact on the gulf- wide bloom distribution.

Forty-three species are represented by vegetative cells and three species only by cysts (P. oblongum, P. cf. stellatum and P. subinerme). Descriptions with an emphasis on the first apical and the second intercalary plates and synonymy are given for each species. Cell size variation, the mean and the standard deviation of three or four measurements are given for most species. The hypothecal pore in the first postcingular plate, a stable taxonomic feature, was observed only in P. solidicorne, P. pellucidum, P. ovum, P. sp. E meta-hexa and P. cf. hirobis; the position of the pore is also a conservative characteristic. Twenty-five species are provided with affinities and taxonomic, nomenclatural or biogeographic comments. A dichotomous key for identification of all the species found is presented, and species are illustrated with light microscope photographs. A new combination is proposed: Protoperidinium persicum (J. Schill.) Okolodkov comb. nov. Fifteen species are new records for the Gulf of Mexico, and about 25 species for the state of Veracruz.

Spatio-temporal variability in fatty acid trophic biomarkers in stomach contents and muscle of Iberian sardine (<i>Sardina pilchardus</i>) and its relationship with spawning	MARINE BIOLOGY			English	Article							GALICIA NW SPAIN; NORTHEASTERN ATLANTIC; SPECIES VARIABILITY; LIPID-COMPOSITION; EGG-PRODUCTION; TELEOST FISH; PLANKTON; INVERTEBRATES; SEASON; GULF	Temporal variation in the fatty acid (FA) composition of stomach contents of Iberian sardines was compared to the relative contribution to dietary carbon made by different prey types for fish from two areas off Portugal. The effect of the FA content of the diet on sardine muscle FA composition was also studied, aiming at (1) analysing if FA biomarkers can be used as a complementary technique for the study of sardine diet and (2) to relate spatial and temporal variations of prey FA content with sardine condition and reproduction. Significant spatial differences in the FA composition of sardine diet occurred with concentrations of n-3 polyunsaturated FA, namely eicosapentaenoic acid [EPA, 20:5n-3] and linolenic acid 18:3n-3, being significantly higher in the diet of sardines from the west coast, whilst the diet of sardines from the south coast was richer in monounsaturated fatty acids (MUFA), namely the carnivory biomarker oleic acid 18:1n-9. These results are in agreement with the higher contribution made by diatoms and dinoflagellates to the diet of sardines off the west coast. Spatial variation in sardine dietary FA was also detected in their muscle composition, specifically for EPA, and the eicosapentaenoic/docosahexaenoic acid and (n-3)/(n-6) ratios, which were higher in sardines from the west coast. No difference in FA composition was detected between sexes, and the seasonal variability in sardine total FA concentration was primarily related to the seasonality of spawning. Sardines accumulate high concentrations of FAs during the resting stage of reproduction when the feeding intensity is similar or lower to that observed during the spawning season. Additionally, sardines show a high selective retention of MUFA and polyunsaturated FA (PUFA) throughout the year except at the beginning of the spawning season, when these FAs are largely invested in the formation of the gonads. Therefore, temporal and regional differences of prey environments are strong enough to be reflected in fish body composition, namely on the accumulation of essential FAs, which can have a strong impact on reproduction success for this species.

Organic-walled dinoflagellate cysts and benthic foraminifera in coastal sediments of the last century from the Gulf of Tehuantepec, South Pacific Coast of Mexico	MARINE MICROPALEONTOLOGY			English	Article						dinoflagellate cysts; Pb-210; Cs-137; benthic foraminifera; Pacific coast; eutrophication; upwelling; Gulf of Tehuantepec	SEA-SURFACE CONDITIONS; ESTUARINE SEDIMENTS; BRITISH-COLUMBIA; NORTH-ATLANTIC; HIGH-LATITUDES; OXYGEN; EUTROPHICATION; INDICATORS; OCEAN; ASSEMBLAGES	Qualitative and quantitative analysis of recent organic-walled dinoflagellate cysts (dinocysts) was performed on surface sediment samples and a core from the continental shelf of the Gulf of Tehuantepec, Mexico, in order to document the spatial distribution of dinocyst assemblages in relation to upwelling and primary productivity, and to assess the environmental history of the last century. The analyses of surface sediment samples show a close relation between dinocyst assemblages and productivity on a regional scale. Polysphaeridium zoharyi and heterotrophic taxa (notably Brigantedinium spp.) dominate in the high productivity zone, whereas Spiniferites delicatus and other phototrophic taxa are more abundant in the lower productivity zone. Sediment in an eighteen cm long gravity core (dated using Pb-210 and Cs-137) provided a record of the last century at annual to decadal resolution, thus yielding a unique opportunity to examine variations in dinocyst assemblages associated with environmental changes. Cyst concentrations in the core range between 477 and 2300 cysts g(-1), giving cyst fluxes between 68 and 494 Cysts cm(-2) yr(-1). Twenty-three phototrophic and heterotrophic cyst taxa were identified. Brigantedinium spp., P zoharyi and Bitectatodinium spongium are dominant, and are associated with the seasonal upwelling that characterizes the area. Cysts of potentially toxic species such as P. zoharyi (the cyst of Pyrodinium bahamense var. compressum and/or bahamense) occur throughout the core. Despite slight variations in relative abundances of the taxa in the assemblages, there is no evidence for eutrophication following industrial development of the adjacent coastal zone. Core samples were also analyzed for benthic foraminiferal content in order to determine possible effects of high, upwelling-induced productivity on bottom water oxygenation. The benthic foraminiferal assemblages are dominated by Hanzawaia concentrica (over 50%), with less abundant Uvigerina excellens, Cancris spp, Planulina ornata, Quinqueloculina lamarckiana, Epistominella sandiegoensis, Nonionella basispinata, Cassidulina modeloensis and Textularia foliacea. The benthic foraminiferal assemblages are characteristic of oxygen concentrations above 1 ml l(-1), indicating that possible changes in productivity did not significantly affect bottom water oxygen concentrations over the last 100 years.

J	Solignac, S; de Vernal, A; Giraudeau, J				Solignac, Sandrine; de Vernal, Anne; Giraudeau, Jacques			Comparison of coccolith and dinocyst assemblages in the northern North Atlantic: How well do they relate with surface hydrography?	MARINE MICROPALEONTOLOGY			English	Article						dinoflagellate cyst; coccolith; North Atlantic; distribution; hydrography; multivariate analysis	NORWEGIAN-GREENLAND SEA; SCALE PHYSICAL CONTROLS; DINOFLAGELLATE CYSTS; NORDIC SEAS; PHYTOPLANKTON GROWTH; LIVING COMMUNITIES; HIGH-LATITUDES; IRMINGER SEA; CIRCULATION; PRODUCTIVITY	Coccolith and dinoflagellate cyst (or dinocyst) population counts were compiled from existing Surface sediment databases as well as new counts in order to establish an 87-sample database for which assemblages of both microfossil groups are known. This database allowed a direct comparison of the distribution of coccolith and dinocyst assemblages in the subtropical to subpolar North Atlantic. In addition, the relationship between these assemblages and sea Surface environmental parameters was addressed, in order to identify possible differences in the ecology of the two plankton groups. The comparison highlights all excellent correspondence between dinocyst assemblages, coccolith assemblages and the distribution of the Surface water masses represented in Our database, notably in the subtropical and temperate domains. In the subpolar domain, coccolith assemblages arc much less diversified than dinocyst assemblages in terms of species. As a result, the discrimination between the subpolar water masses based oil coccolith assemblages is not as clear as in the subtropical/temperate regions, whereas dinocyst assemblages show a distribution pattern closely related with surface hydrography. Canonical correspondence analyses performed oil coccolith and dinocyst assemblages show that sea surface temperature is the primary environmental parameter influencing the distribution of both groups. Dinocyst assemblages also seem to respond to the distance to the coast, and may therefore bring additional information compared with coccolith assemblages. Other significant environmental factors include sea surface salinity and productivity, but their relative importance changes depending on the inclusion of samples from extreme environmental settings in the database. Results suggest that the complexity of the interrelationships between the various environmental parameters makes it difficult to adequately bring to light all the different environments and their associated coccolith/dinocyst assemblages in multivariate analyses. However, each surface water mass represented ill Our database is characterized by a unique combination of environmental parameters as well as by distinct associations of coccolith and dinocyst assemblages, thus showing that these microfossil groups closely relate to sea Surface conditions, including temperature, salinity and productivity.

Here, we review the information currently available on this topic. After discussing organic matter degradation in general, an overview on the effects of different laboratory treatments on the dinoflagellate cyst association is given. Hereafter, the rates and amount of species-selective degradation in modern and fossil natural environments are discussed. it appears that the availability of oxygen in the sediments is the most important diagenetic variable. Some of the modern dinoflagellate cyst species survive thousands of years in well oxygenated sediments and are as such among the most refractory types of organic matter. Most (but not all) of these refractory species are phototrophic gonyaulacoids. However, the refractory cysts form only a part of the modern gonyaulacoid or phototrophic cyst producing taxa. The modem species most vulnerable to degradation are often produced by heterotrophic peridinioids. Again, these Vulnerable species form only a part of the heterotrophic species and species with a peridinioid plate configuration. To get insight in the intrinsic properties of the cysts bringing about the selective preservation, we continue with reviewing the understanding of algal cell walls and dinoflagellate cyst walls at the molecular level. The review documents that cysts of Mesozoic age have different preservation characteristics than Late Cenozoic to Modern species. We propose that over long periods, taphonomic processes on a molecular level substantially change the cyst wall macromolecular structure and herewith cyst degradability. Having described the impact of selective preservation on the dinoflagellate cyst assemblages, we continue summarising the methods presently available for the recognition of and correction for this diagenetic overprint. Subsequently, we take advantage of the selective preservation by using it for reconstructing past export production. Since the rates of dinoflagellate cyst degradation are strongly related to the bottom water oxygen concentration, this opens the way for a new proxy to reconstruct deep-ocean oxygen concentrations. The importance of the rate of deep-ocean ventilation within the marine global carbon cycle and its relationship with climate change, make this use of selective dinoflagellate cyst preservation an important though unexpected application.

The interrelation study between the occurrence of the blooms and specific external conditions at the study sites demonstrated that different factors are required for the bloom of each Alexandrium species. Concentrations higher than 105 cells 1(-1) of A. catenella were only detected in Tarragona harbour. These blooms were associated with water surface temperature between 21 and 25 degrees C and salinities of around 34 psu or higher than 37 psu. A. minutum appeared widely spread along the Catalan coast, though the most intensive and recurrent blooms of this species were observed in Arenys de Mar harbour. Concentrations of millions of cells per litre of A. minutum were associated with water temperatures below 14 degrees C and salinities of around 34-36 psu. A. minutum cell densities showed a positive significant correlation with NO3 but a negative correlation with NH4. On the other hand, A. catenella blooms dominated when both NO3 and NH4 levels were high. The prevailing inorganic nitrogen form (NO3 vs. NH4) could explain why these two species rarely coincide in the same harbours. Accumulation of cysts in the sediment was found to be an important potential factor for the recurrence of these spocies. The 4.3 x 10(3) A. catenella Cysts cm(-3) of wet sediment in Tarragona harbour and the 3.02 x 10(3) A. minutum Cysts cm(-3) of wet sediment in Vilanova harbour were the highest concentrations observed from the cyst study. Confined waters such as harbours play an important role as reservoirs for the accumulation of cysts and vegetative cells, which contributes to the expansion of these dinoflagellates in the region.

At least 17 dinoflagellate cyst species, including those of the toxic species, Pyrodinium bahamense var. compressum, were identified. P. bahamense may have been present in the area since at least the 1920s. Total cyst density has increased beginning about 1988 to 1998 coinciding with records of P. bahamense blooms in the area. Heterotrophs have always dominated the cysts assemblage. These changes in the dinoflagellate record and the P. bahamense blooms in recent years may have been induced by the interplay of warmer temperatures, high rainfall leading to higher river discharge and less turbulent waters due to passage of few tropical cyclones.

Toxic species post an additional treat of intoxication when consumed either in seafood or directly swallowed. Rapid and accurate identification of the HAB species is critical for minimizing or controlling the damage. We report the use of protein/peptide mass fingerprint profiles obtained with matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry (MS) for the identification of dinoflagellates, common causative agents of HABs. The method is simple, fast and reproducible. The peptide mass fingerprint spectral patterns are unique for different dinoflagellate species and are easily distinguishable by visual inspection. In addition to the whole mass spectra, several specific biomarkers were identified from the mass spectra of different species. These biomarker ions and the mass spectral patterns form an unambiguous basis for species discrimination. (C) 2007 Elsevier B.V. All rights reserved.

We incubated G. instriatum in modified whole SWM-3 culture medium and in ver- sions of modified SWM-3 from which NO(3)(-), PO(4)(3-), NO(3)(-) + PO(4)(3-), or Si had been omitted and observed encystment. Percentage encystment was high in the media without N and without P, while the percentage encystment in the medium lacking both N and P was highest. Moreover, to investigate N or P concentration which induced the encystment, Gyrodinium instriatum was also incubated in media with different concentrations of inorganic N and P; the concentrations of NO(2)(-) + NO(3)(-) and PO(4)(3-) were measured over time. The precursors of cysts appeared within 2 or 3 days of a decrease in NO(2)(-) + NO(3)(-) or PO(4)(3-) concentration to values lower than 1 mu M or 0.2 mu M, respectively. When cysts produced in the laboratory were incubated, we observed excystment after 8-37 days, without a mandatory period of darkness or low temperature. We incubated cysts collected from nature at different temperatures or in the dark or light and observed excystments. Natural cysts excysted at temperatures from 10 to 30 degrees C, in both light and dark, but excystment was delayed at low temperatures. These studies indicate that G. instriatum encysts in low N or P concentration and excysts over a wide temperature range, regardless of light conditions, after short dormancy periods.

Urea is preferentially used as a nitrogen source by some cyanobacteria and dinoflagellates, many of which are neutrally or positively buoyant. Biological pumps to the deep sea are classically leaky, and the inefficient burial of new biomass makes the estimation of a net loss of carbon from the atmosphere questionable at best. The potential for growth of toxic dinoflagellates is also high, as many grow well on urea and some even increase their toxicity when grown on urea. Many toxic dinoflagellates form cysts which can settle to the sediment and germinate in subsequent years, forming new blooms even without further fertilization. If large-scale blooms do occur, it is likely that they will contribute to hypoxia in the bottom waters upon decomposition. Lastly, urea production requires fossil fuel usage, further limiting the potential for net carbon sequestration. The environmental and economic impacts are potentially great and need to be rigorously assessed. (C) 2008 Elsevier Ltd. All rights reserved.

As a consequence, the life cycle of these algae has been extensively studied, but the dormancy phase (cyst) in the sediment record is little known. In the intertidal zone, bioturbation, an important biological process resulting from the activities of benthic fauna, significantly influences the movement of particles in the sediments. Laboratory experiments have allowed comparing and quantifying the movements of fluorescent microspheres resulting from the activity of two polychaetes annelidae, Nereis virens and Nephtys caeca. The particles, which simulate 45 mu m diameter dinoflagellate cysts, are deposited in flat aquaria at the surface or deep in the sediment. Photographs of the aquaria were taken at regular intervals, to observe, in a non-destructive manner, the movement of the particles and to calculate, using adapted software, the optical reworking coefficient (ORC) over time. A difference appears between the movements of the particles generated by both species of polychaetes. Nereis virens create "permanent" galleries that carry the microspheres deeply in the sediment during the digging, bioirrigation and feeding, and Nephtys caeca homogenize the particles in the first centimetres of sediment during its erratic movements. The study shows that the bioturbation generated by these organisms can modify the distribution of the 45 mu m diameter dinoflagellate cysts in the sedimentary column, burying them or raising them back to the water-sediment interface.

To differentiate C. polykrikoides from C. convolutum, the shape and the position of the nucleus are useful characters. C. polykrikoides also differs from C. fulvescens in being smaller in size, possessing many rod-shaped chloroplasts and having the sulcus running just below the cingulum on the dorsal surface. Careful observation of the ichnotype of C. catenatum suggests that C. catenatum sensu Kofoid and Swezy collected from off La Jolla, CA, USA, is not identical to C. catenatum sensu Okamura and is probably a different species, in having no chloroplasts and a nucleus positioned at the center of the cell. In addition, C. polykrikoides has many morphological features in common with C. catenatum sensu Okamura except for slightly elongate cells and is probably a junior synonym of this species.

J	Tomas, CR; Smayda, TJ				Tomas, Carmelo R.; Smayda, Theodore J.			Red tide blooms of <i>Cochlodinium polykrikoides</i> in a coastal cove	HARMFUL ALGAE			English	Article						Cochlodinium polykrikoides; harmful bloom; Narragansett Bay region	DINOFLAGELLATE; GROWTH; DINOPHYCEAE; GYMNODINIALES; WATERS; CYCLE	Successive blooms of the dinoflagellate Cochlodinium polykrikoides occurred in Pettaquamscutt Cove, RI, persisting from September through December 1980 and again from April through October 1981. Cell densities varied from <100 cells L-1 at the onset of the bloom and reached a maximum density exceeding 3.4 x 10(6) cells L-1 during the summer of 1981. The bloom was mainly restricted to the mid to inner region of this shallow cove with greatest concentrations localized in surface waters of the southwestern region during summer/fall periods of both years. Highly motile cells consisting of single, double and multiple cell zooids were found as chains of 4 and 8 cells restricted to the late August/September periods. The highest cell densities occurred during periods when annual temperatures were between 19 and 28 degrees C and salinities between 25 and 30. A major nutrient source for the cove was Crying Brook, located at the innermost region at the head of the cove. Inorganic nitrogen (NH3 and NO2 + NO3) from the brook was continually detectable throughout the study with maximum values of 57.5 and 82.5 mu mol L-1, respectively. Phosphate (PO4-P) was always present in the source waters and rarely <0.5 mu mol L-1; silicate always exceeded 30 mu mol L-1 with maximum concentrations reaching 226 mu mol L-1. Chlorophyll a and ATP concentfations during the blooms varied directly with cell densities. Maximum Chi a levels were 218 mg m(-3) and ATP-carbon was >20 g C m(-3). Primary production by the dinoflagellate-dominated community during the bloom varied between 4.3 and 0.07 g C m(-3) d(-1). Percent carbon turnover calculated from primary production values and ATP-carbon varied from 6 to 129% d(-1). The dinotlagellates dominated the entire summer period; other flagellates and diatoms were present in lesser amounts. A combination of low washout rate due to the cove dynamics, active growth, and life cycles involving cysts allowed C. polykrikoides to maintain recurrent bloom populations in this area.

We used stratigraphically well-documented first occurrences of particular archeopyle types to constrain relaxed Bayesian molecular clocks applied to nuclear rRNA sequences of 18 representatives of the three main clades. By comparing divergence estimates obtained in differently calibrated clocks with first stratigraphic occurrences of taxa not themselves used as constraints, we identified plausible divergence times for several subclades of calcareous dinoflagellates. The initial diversification of extant calcareous dinoflagellates probably took place in the Late Jurassic, with the three main clades all established by the Cretaceous. The two mesoepicystal operculum types observed in calcareous dinoflagellates probably evolved independently from simple apical archeopyles. Based on our taxon sample, the K/T boundary had relatively little effect on the diversity of the group, with several lineages dating to before 65 mya (million years ago). The first stratigraphic occurrences of key taxa, such as Thoracosphaera and Calciodinellum (not themselves used as constraints), are in agreement with the molecular time estimates. Conflicts that involve "Calciodinellum" levantinum, Leonella, Pentapharsodinium, Pernambugia, and the Scrippsiella trochoidea species complex may be due to inaccurate assignment of fossils because of high morphological homoplasy and insufficient knowledge of the extant diversity of calcareous dinoflagellates.

Identification of Scrippsiella species requires information on cyst morphology because the plate pattern of the flagellated cell is conserved. Cysts from sediments of the East China Sea were identified based on traits from both the cysts and the thecal patterns of germinated cells. Calcareous cysts belonged predominantly to S. trochoidea (F. Stein) A. R. Loebl., S. rotunda J. Lewis, and S. precaria Montresor et Zingone. The former two species also produced smooth and noncalcified cysts in the field. A new species, S. donghaienis H. Gu sp. nov, was obtained from six noncalcified cysts with organic spines. These cysts are spherical, full of pale white and greenish granules with a mesoepicystal archeopyle. The vegetative cells consist of a conical epitheca and a round hypotheca with a plate formula of po, x, 4', 3a, 7 '', 6c (5c + t), 6 s, 5''', 2'''' and are morphologically indistinguishable from S. trochoidea. Results of internal transcribed spacer (ITS) sequence comparisons revealed that S. donghaienis was distinct from the S. trochoidea complex and appeared nested within the Calciodinellum/Calcigonellum clade. Culture experiments showed that the presence of a red body in the cyst and the shape of the archeopyle were constant within cell lines from one generation to the next, while the morphological features of the cyst wall, such as calcification and spine shape, appeared to be phenotypically plastic.

Two stations (D1 and D2) were sampled on June 24, and D2 was resampled 6 days later; chlorophyll-a concentration had decreased by about one half. LAC MODIS-Chla images were obtained and showed the spread of the bloom on the day after sampling. The phytoplankton community consisted primarily of dinoflagellate temporary cysts, mainly at the surface and at 5 m in station D1. Two Pseudo-nitzschia species (P. australis, P. seriata) were also very abundant. Samples from the bloom had a specific phytoplankton absorption coefficient (a*(ph)(lambda)) lower than the rest of the samples. Values varied from 0.0186 to 0.0455 m(2) mg(-1) for a*(ph)(440) and from 0.0092 to 0.0294 m(2) mg(-1) for a*(ph) (675), with ratios a*(ph)(440): a*(ph)(675) ranging from 0.99 to 2.20. These low ratios were associated with the combined effect of packaging, and with the relatively high ratios of fucoxanthin, peridinin, diadinoxanthin and chlorophyll-c2 to TChla. Samples from the surface and 5 m depth at station D1 had higher ratios of Perid:TChla (0.12-0.32) than the rest of the samples, suggesting that cysts have similar Perid:TChla as free-living dinoflagellates. An unusual absorption spectrum with a broad maximum around 480-500 nm was associated with the high proportion of cysts and diatoms. The slope of the spectra between 443 and 488 nm was a good index to differentiate bloom samples containing high proportions of dinoflagellate temporary cysts. Further investigation of the absorption properties of dinoflagellate cysts is needed in order to detect these waters by remote sensing. Although much work is still necessary to understand and explain the bio-optical properties of a bloom, the present study is the first assessment off the Baja California coast to simultaneously consider aspects such as absorption properties, pigment composition and to include a spatial evaluation of the extension of a bloom with satellite images.

Since the South West Monsoon (SWM) is the main source of climatic variation, observations were made during two consecutive post-monsoon periods (2001 and 2002) and the intervening pre-monsoon period (2002). The pre-monsoon period supported a more diverse dinoflagellate community in the water column compared to both post-monsoon periods. Heterotrophic dinoflagellates were abundant in the water column as well as sediment. A seasonal cycling between vegetative and resting cysts of autotrophic and heterotrophic dinoflagellates governed by the environmental characteristics of the study area was observed. Temperature, salinity and suspended particulate matter were the main factors affecting dinoflagellate community structure in both the water column and sediment. The dominant dinoflagellates in the water column differed during both post-monsoon periods that followed two dissimilar monsoon events. Prorocentroids and gonyaulacoids dominated the water column subsequent to the 2001 SWM, whereas dinophysoids and unidentified tiny dinoflagellates dominated during the next post-monsoon period. The 2001 SWM started in May, peaked during June-July and reduced gradually to end in October. The 2002 SWM was erratic; it started late (in June) and ended earlier (in September). These observations highlight the potential of the SWM to influence the community structure of dinoflagellates in tropical waters and points to the importance of long-term studies to discern robust variations in dinoflagellate communities in response to fluctuating monsoon regimes.

Isolation of tissue layers in hermatypic corals by <i>N</i>-acetylcysteine:: morphological and proteomic examinations	CORAL REEFS			English	Article						epidermis; gastrodermis; proteomics; endosymbiosis; Symbiodinium	ACETYL-L-CYSTEINE; MUCOLYTIC AGENT; HYDRA; REDUCTION; SYMBIOSIS; ENDODERM; MESOGLEA; PROTEIN	Corals are diploblastic in body pattern and include two tissue layers, the epidermis and gastrodermis, interconnected by an acellular matrix mesoglea. During development, cells in these tissue layers differentiate morphologically and functionally. In most hermatypic corals, the gastrodermis further develops an ability to associate with microalgae dinoflagellates. This endosymbiosis occurs inside specific host gastrodermal cells, and its mechanism still remains unclear notwithstanding decades of research. The delay in progress is partly due to the difficulty in separating the gastrodermis and its symbionts from the epidermis for detailed cellular and biochemical investigations. The present study reports a simple method to separate these two tissue layers in hermatypic corals using the reducing agent, N-acetylcysteine (NAC). Efficient tissue and proteomic isolations are demonstrated by microscopy and two-dimensional SDS polyacrylamide gel electrophoresis (2D SDS-PAGE). The NAC treatment was able to separate tissue layers without inducing protein degradation. Furthermore, the sensitivity of protein detection greatly increases in the isolated tissue layers. The application of the present technique provides future research on endosymbiosis and coral development with a tool for higher accuracy and sensitivity.

Morphological variation and phylogenetic analysis of the dinoflagellate <i>Gymnodinium aureolum</i> from a tributary of Chesapeake Bay	JOURNAL OF EUKARYOTIC MICROBIOLOGY			English	Article						Chesapeake Bay; dinoflagellate; Gymnodinium aureolum; Gymnodinium maguelonnense; LSU rDNA sequence; morphological variation	SP-NOV GYMNODINIALES; GYRODINIUM-AUREOLUM; DINOPHYCEAE; ULTRASTRUCTURE; KARENIA; GENERA; INFERENCE; TASMANIA; MRBAYES; CYSTS	Cultures of four strains of the dinoflagellate Gymnodinium aureolum (Hulburt) G. Hansen were established from the Elizabeth River, a tidal tributary of the Chesapeake Bay, USA. Light microscopy, scanning electron microscopy, nuclear-encoded large sub-unit rDNA sequencing, and culturing observations were conducted to further characterize this species. Observations of morphology included: a multiple structured apical groove; a peduncle located between the emerging points of the two flagella; pentagonal and hexagonal vesicles on the amphiesma; production and germination of resting cysts; variation in the location of the nucleus within the center of the cell; a longitudinal ventral concavity; and considerable variation in cell width/length and overall cell size. A fish bioassay using juvenile sheepshead minnows detected no ichthyotoxicity from any of the strains over a 48-h period. Molecular analysis confirmed the dinoflagellate was conspecific with G. aureolum strains from around the world, and formed a cluster along with several other Gymnodinium species. Morphological evidence suggests that further research is necessary to examine the relationship between G. aureolum and a possibly closely related species Gymnodinium maguelonnense.

They are particularly diverse in the marine plankton where some cause "red tides" and other harmful blooms. More than 2,000 extant species have been described, only half of which are photosynthetic. They include autotrophs, mixotrophs and grazers. They are biochemically diverse, varying in photosynthetic pigments and toxin production ability. Some are important sources of bioluminescence in the ocean. They can host intracellular symbionts or be endosymbionts themselves. Most of the photosynthetic "zooxanthellae" of invertebrate hosts are mutualistic dinoflagellate symbionts, including all those essential to reef-building corals. Roughly 5% are parasitic on aquatic organisms. The fossil record, consisting of more than 2,500 species, shows a rapid radiation of cysts, starting in the Triassic, peaking in the Cretaceous, and declining throughout the Cenozoic. Marine species with a benthic, dormant cyst stage are confined to the continental shelf and fossil cysts can be used as markers of ancient coastlines. Northern and southern hemispheres contain virtually identical communities within similar latitudes, separated by a belt of circumtropical species. A few endemics are present in tropical and polar waters. Some benthic dinoflagellates are exclusively tropical, including a distinct phycophilic community, some of which are responsible for ciguatera fish poisoning. In lakes chemical and grazing effects can be important. Predatory dinoflagellates co-occur with their prey, often diatoms.	[Taylor, F. J.

The parasite possessed a combination of features described for perkinsids and syndineans, and also possessed novel characters associated with its parasitic life cycle. Reniform zoospores, about 4 mu m long, possessed a transverse flagellum, alveoli, a refractile body, a mitochondrion with tubular cristae, a syndinean-like nucleus with condensed chromatin, micronemes, bipartite trichocysts with square profiles (absent in perkinsids) and oblong microbodies. Like Parvilucifera, the zoospores also possessed a shorter posterior flagellum, a heteromorphic pair of central microtubules in the anterior axoneme and a reduced pseudoconoid positioned directly above an orthogonal pair of basal bodies. Early developmental stages consisted of a sporangium about 5-15 mu m in diam that contained spherical bodies and amorphous spaces. The undifferentiated sporangium increased to about 20-25 mu m in diam before being enveloped by a wall with a convoluted mid-layer. The sporangium differentiated into an unordered mass of zoospores that escaped from the cyst through a pronounced germ tube about 4-5 mu m in diam and 10-15 mu m long. Weakly developed germ tubes have been described in Perkinsus but are absent altogether in Parvilucifera and syndineans. Comparison of these data with other myzozoans led us to classify the parasite as Parvilucifera prorocentri sp. nov., Myzozoa. Although we were hesitant to erect a new genus name in the absence of molecular sequence data, our ultrastructural data strongly indicated that this parasite is most closely related to perkinsids and syndineans, and represents an intriguing candidate for the cellular identity of a major subclade of Group I alveolates.

To understand the whole picture regarding the ecology of this species, it is essential to clarify its overwintering mechanisms. In this study, the population dynamics of H. circularisquama were investigated from February 2004 to November 2005, and overwintering cells were identified for the first time in water columns of Uranouchi Inlet, Kochi Prefecture, Japan. Heterocapsa circularisquama cells were detected by the indirect fluorescent antibody technique using monoclonal antibodies that specifically recognize and react to this species. Vegetative cells were almost always detected from the first observation in February 2004 to November 2005 with temperatures of 10.5-30.6 degrees C. During the period from winter to spring, this species survived in areas with a temperature higher than 10 degrees C. The overwintering cells of H. circularisquama were isolated in March 2004, and identification was made via observation of the morphology and body scales of the cultured cells. These overwintering cells were identified as H. circularisquama and reacted to the monoclonal antibody. These results indicate that H. circularisquama can overwinter and survive throughout the year in a vegetative cell state in Uranouchi Inlet.

To investigate the effects and practicability of this HAB mitigation method, field experiments were carried out during a Cochlodinium bloom near Miruk Island, South Korea, in August 2002. Field experiments examined the effects of sophorolipid and yellow clay on Cochlodinium bloom mitigation and on marine plankton such as bacteriaplankton, heterotrophic protists, and zooplankton. A mixture of 5 mg l(-1) sophorolipid and 1 g l(-1) yellow clay was sprayed directly on the sea surface and its effect was compared with that of 10 g l(-1) of yellow clay applied under similar conditions. The sophorolipid-yellow clay mixture more efficiently mitigated the Cochlodinium bloom (95% removal efficiency after 30 min) than yellow clay alone (79% after 30 min). Further, no variation in bacterial abundance occurred 30 min after spraying the sophorolipid-yellow clay mixture. After 30 min, heterotrophic protist abundance at the surface decreased 21 and 41 %, respectively, following the sophorolipid-yellow clay mixture and yellow clay treatments. Zooplankton decreased by 38% 15 min after spraying the mixture and 67% 30 min after spraying the yellow clay. These results indicate that the mixture of sophorolipid and yellow clay had a less adverse effect on bacteriaplankton, heterotrophic protists, and zooplankton than the yellow clay, suggesting that the sophorolipid-yellow clay mixture can mitigate HABs efficiently with fewer negative effects on the pelagic ecosystem.

A first coupled physical-biological model of A. tamarense blooms was developed for this system in order to explore the interactions between cyst germination, cellular growth and water circulation and to identify the effect of physical processes on bloom development and transport across the estuary. The simulated summer (1998) was characterized by an A. tamarense red tide with concentrations reaching 2.3 x 10(6) cells L-1 along the south shore of the LSLE. The biological model was built with previously observed A. tamarense cyst distribution, cyst germination rate and timing, and A. tamarense growth limitation by temperature and salinity. The coupled model successfully reproduced the timing of the A. tamarense bloom in 1998, its coincidence with the combined plumes from the Manicouagan and Aux-Outardes (M-O) rivers on the north shore of the estuary, and the temporal variations in the north-south gradients in cell concentrations. The simulation results reveal that the interaction between cyst germination and the estuarine circulation generates a preferential inoculation of the surface waters of the M-O river plume with newly germinated cells which could partly explain the coincidence of the blooms with the freshwater plume. Furthermore, the results suggest that the spatio-temporal evolution of the bloom is dominated by alternating periods of retention and advection of the M-O plume: east or northeast winds favor the retention of the plume close to the north shore while west or north-west winds result in its advection toward the south shore. The response of the simulated freshwater plume to fluctuating wind forcing controls the delivery of the A. tamarense bloom from the northern part of the estuary to the south shore. In addition, our results suggest that a long residence time of the M-O plume and associated A. tamarense population in the LSLE during the summer 1998 contributed to the development of the red tide. We thus hypothesize that the wind-driven dynamics of the M-O plume could partly determine the success of A. tamarense blooms in the LSLE by influencing the residence time of the blooms and water column stability, which in turn affects A. tamarense vertical migrations and growth.

Indeed, shellfish containing toxic algal cells can induce both primary contaminations in safe areas ( initially free from toxic microalgae), and secondary contaminations of other shellfish growing in the same area via the faeces of the imported animals. To mitigate this problem, shellfish need to be placed in a separate holding tank and their intestinal content purged. For a deeper understanding of the risks associated with transferring contaminated shellfish, oysters ( Crassostrea gigas) and mussels ( Mytilus edulis) were purposely fed either Alexandrium minutum or A. catenella ( Dinophyceae) or Pseudo- nitzschia calliantha ( Bacillariophyceae) toxic algae for 2 h. They were then transferred into individual tanks where they were continuously fed with a non- toxic alga, Tetraselmis suecica. Biodeposit production, faeces composition, and filtration rates were monitored for the shellfish over a 6- h period. The effect of temperature differences and different initial toxic algae concentrations were compared. This study revealed a relationship between temperature and cell lysis in the oyster digestive tract. It also indicated that toxic algae concentration did not seem to influence gut passage time in oysters, while a significant effect was observed in mussels, and confirmed the existence of a difference between oyster and mussel feeding patterns.

By coupling field and laboratory experiments, the present study is the first to analyze the dynamics of vegetative cells and sexual stages during a bloom of G. catenatum. In natural samples, the sexual stages of G. catenatum were associated with several different cellular behaviors and morphologies. This confirmed laboratory evidence for the reversibility of the species' sexual processes and for the ability of zygotes to either bypass or shorten the route to resting-cyst formation. Moreover, chains of up to 4 viable cysts with differing morphologies occurred and these have never been reported previously for this species. At least two of the cysts had reticulated surfaces, a feature related to sexual reproduction in previous studies; this observations suggests the involvement of sexual processes in mechanisms that cannot be explained by any known life cycle route depicted for this species. Morphological variability and abundance of the sexual stages during the bloom indicated the complexity of the G. catenatum sexual cycle and the important role of sexual reproduction in the ecological succession of this species. However, the lack of a dormancy period in the sexual resting stage (evidenced by the large number of germinated cysts in sediments sampled 3 mo after the bloom) indicated that the advection of offshore populations shoreward, rather than 'seed beds', is the main mechanism explaining G. catenatum bloom formation in the Galician rias.

In mid-January local residents reported bioluminescence in the Sea. Starting in February, large rafts of long-lasting foam, also bioluminescent, were observed as well. Microscopy investigations on water and sediment samples collected in March showed the marine dinoflagellate, Alexandrium margalefii, and the prymnesiophyte, Prymnesium sp., both previously unreported in the Salton Sea, to be abundant. Bioluminescence and foam production continued through March. Other dinoflagellate species, recorded during earlier studies, were rare or not detected during these blooms. Despite the fact that many Alexandrium species are known paralytic shellfish poison (PSP) producers, preliminary saxitoxin tests on this population of A. margalefii were negative. Previous reports on A. margalefii do not mention bioluminescence. It appears that the foam was caused by the Prymnesium sp. bloom, probably via protein-rich exudates and lysis of other algal cells, and its glow was due to entrained A. margalefii. This is the first report of A. margalefii in U.S. waters and the first report of it in a lake.

The presence of the genus Gambierdiscus in Crete since 2003 constituted the earliest record of this genus in the Mediterranean Sea. The epiphytic dinoflagellate community comprised the genera Gambierdiscus, Ostreopsis, Coolia, Prorocentrum, Amphidinium and the non- photosynthetic benthic species Sinophysis canaliculata. The last species was also recorded for the first time in the Mediterranean Sea in the present study. Furthermore, diatoms of the genera Coscinodiscus, Licmophora and Striatella were observed as well. Sinophysis canaliculata cells fitted in the earlier descriptions of the species bearing the characteristic hole on the left lateral hypothecal plate. Gambierdiscus cells from both field samples and cultures were round to ellipsoid in shape ( dorsoventral diameter / transdiameter ratio, DV/ W: 1.02 +/- 0.06) and anterior- posteriorly compressed ( AP < 45 mu m), while field specimens ( DV: 57.12- 76.16 mu m, W: 52.36- 78.54 Im) were found to be smaller than those grown in culture conditions ( DV: 69.02- 84.49 mu m, W: 69.02- 85.68 mu m). Specific discriminative characteristics of Gambierdiscus specimens examined in this study, such as the thecal surface pattern and the posterior plate ( 1p), fitted well with those of the " G. toxicus type"; nevertheless, our specimens were not assigned to a species due to inconsistencies revealed lately regarding the identity of the type species.

The Eastern mudsnail, <i>Ilyanassa obsoleta</i>, actively forages for, consumes, and digests cysts of the dinoflagellate, <i>Scrippsiella lachrymosa</i>	MALACOLOGIA			English	Article						deposit feeding; dinoflagellate resting stages; cyst ecology	DEPOSIT-FEEDERS; RESTING CYSTS	The Eastern mudsnail, Ilyanassa obsoleta, was attracted to, consumed, and digested resting cysts of the dinoflagellate Scrippsiella lachrymosa when cysts were presented in grazing experiments. Twenty snails were observed individually for one hour in petri dishes divided into four parts wherein cysts were present in one quadrant, sediment particles of the same size range were in another quadrant, and two quadrants were free of particles. Actively foraging snails were nearly twice as likely to be found in quadrants containing S. lachrymosa cysts as in the other quadrants until cysts were consumed. Microscope observations of fecal pellets from snails feeding on cysts revealed digestive destruction of the cysts. These findings indicate that deposit-feeding grazers can actively seek dinoflagellate cysts as a food item, thereby influencing distribution of cysts and subsequent germination of dinoflagellate vegetative cells.

Potential transport of harmful algae via relocation of bivalve molluscs	MARINE ECOLOGY PROGRESS SERIES			English	Article						bivalve mollusc; harmful algal bloom; toxic algae; transport; clam s; scallop; oyster	OYSTER CRASSOSTREA-GIGAS; ALEXANDRIUM-CATENELLA; GUT PASSAGE; DINOFLAGELLATE CYSTS; MYTILUS-EDULIS; DINOPHYCEAE; BLOOMS; INGESTION; VIABILITY; VIRGINICA	Aquaculture and restoration activities with bivalve molluscs often involve moving individuals from one body of water to another. Our study tests the hypothesis that harmful algae ingested by source populations of shellfish can be introduced into new environments by means of these shellfish relocations. Cultures of several harmful algal strains, including Prorocentrum minimum, Alexandrium fundyense, Heterosigma akashiwo, Aureococcus anophagefferens, Karenia mikimotoi and Alexandrium monflatum, were fed to various species of bivalve molluscs, Crassostrea virginica, Argopecten irradians irradians, Mercenaria mercenaria, Mytilus edulis, Mya arenaria, Venerupis philippinarum and Perna viridis, to assess the ability of the algal cells to pass intact though the digestive tracts of the shellfish and subsequently multiply in number. Ten individuals of each shellfish species were exposed for 2 d to it simulated harmful algal bloom at a natural bloom concentration. The shellfish were removed after exposure, and maintained for 2 further days in ultra-filtered seawater. Biodeposits (feces) were collected after 24 and 48 additional hours, and observed under light microscopy for the presence or absence of intact, potentially viable algal cells or temporary cysts. Subsamples of biodeposits were transferred into both algal culture medium and filtered seawater and monitored for algal growth. Intact cells of most harmful algal species tested were seen in biodeposits. Generally, harmful algae from the biodeposits collected in the first 24 h after transfer re-established growing populations, but algae could less often be recovered from the biodeposits collected after 48 h. These data provide evidence that transplanted bivalve molluscs may be vectors for the transport of harmful algae and that a short holding period in water without algae may mitigate this risk. Further, preliminary results indicate that emersion may also serve to mitigate the risk of transport.

Microplankton composition off NW Iberia at the end of the upwelling season: source areas of harmful dinoflagellate blooms	MARINE ECOLOGY PROGRESS SERIES			English	Article						harmful dinoflagellates; coastal upwelling; Iberian poleward current; subsurface chlorophyll maximum; NW Iberia; rias baixas	RIA-DE-VIGO; POLEWARD CURRENT; RED TIDES; SPAIN; SYSTEM; COAST; GULF; FLOW; CIRCULATION; ATLANTIC	The Rias Baixas of Galicia are 4 bays on the NW Iberia Peninsula that experience harmful dinoflagellate blooms toward the end of the upwelling season, in late summer to early autumn. In order to identify the source areas of initial bloom populations, we studied the hydrographic regime and the microplankton composition in the NW Iberian margin at the end of summer 1991. Three distinctive oceanographic features were recognised as possible sources of initial populations: (1) the onset of a northward stream, the Iberian Poleward Current (IPC), which can transport seed populations to the region; (2) a subsurface chlorophyll maximum (SCM); and (3) weak upwelling at the coast, which can promote the growth of dinoflagellates. While the SCM held populations of the small dinoflagellates Heterocapsa niei and Prorocentrum minimum, larger dinoflagellates Prorocentrum micans, Dinophysis acuminata, Gymnodinium catenatum and the raphidophycean Heterosigma akashiwo, which habitually form blooms in the Rias Baixas, were only found in upwelled coastal waters, mostly off the Rias. These species occurred with a microplankton assemblage composed of other large dinoflagellates and diatoms, which is characteristic of the final summer upwelling events in the Rias. It is hypothesised that the Rias Baixas can be both the source and the target of harmful dinoflagellate blooms. Summer upwelling, through cyst resuspension and subsequent germination in the nearby stratified waters, would provide the initial populations. Downwelling, which promotes the accumulation of dinoflagellates in the interior of the Rias, would ensure blooms and hence replenish the sediments with new cysts.	[Crespo, B. G.; Teixeira, I.

Italy, and on <i>B-tenuissima</i> comb. nov (syn. <i>Woloszynskia tenuissima</i>)	PHYCOLOGIA			English	Article						freshwater; dinoflagellates; ultrastructure; taxonomy; phylogeny	FLAGELLAR APPARATUS; DINOPHYCEAE; DNA; ARCHITECTURE; MORPHOLOGY; POLARELLA; NETWORK; GROWTH; LIGHT	Using ultrastructure and nuclear-encoded large subunit (LSU) rDNA sequences, the woloszynskioid dinoflagellates have been shown recently to form a polyphyletic assemblage. The first group comprises the family Tovelliaceae, with the genera Tovellia and Jadwigia. The present manuscript describes the second group, comprising Borghiella dodgei gen. et sp. nov. from the Italian Alps. The new genus differs in a number of ultrastructural features, of which the most important are the structure of the eyespot (type B sensu Moestrup & Daugbjerg) and the structure of the apical part of the cell. The resting cyst is smooth, in contrast to the cysts of other woloszynskioids such as Tovellia and some species of Woloszynskia. The new species has been previously confused with Tovellia sanguinea, which was responsible for colouring the water of Lake Tovel, in the Italian Alps, blood-red up to 1964. However, B. dodgei may form brown, never truly red blooms as in the case of T. sanguinea. The transverse flagellum of Borghiella carries, in addition to thin hairs found also in other dinoflagellates, a row of shorter, thicker hairs resembling the curly hairs on the homologous, anterior flagellum of the perkinsid Parvilucifera but apparently not observed in any other dinoflagellates. Woloszynskia tenuissima, a well-known cold-water dinoflagellate, has been re-examined using material isolated from Greenland. Based on partial LSU rDNA sequencing it is shown to be related to R dodgei (sequence divergence only 1.1%) and is transferred to this genus as B. tenuissima comb. nov. We agree with the observations of von Stosch that the cysts of this species are spherical and smooth, in contrast to what was mentioned in the original description by Woloszynska.

A universal driver of macroevolutionary change in the size of marine phytoplankton over the Cenozoic	PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA			English	Article						cell size; climate change; dinoflagellates; evolution; food webs	GROWTH-RATES; FOOD WEBS; BODY-SIZE; FEEDING-BEHAVIOR; EVOLUTION; PLANKTON; CLIMATE; ZOOPLANKTON; ASSEMBLAGES; DIATOMS	The size structure of phytoplankton assemblages strongly influences energy transfer through the food web and carbon cycling in the ocean. We determined the macroevolutionary trajectory in the median size of dinoflagellate cysts to compare with the macroevolutionary size change in other plankton groups. We found the median size of the dinoflagellate cysts generally decreases through the Cenozoic. Diatoms exhibit an extremely similar pattern in their median size over time, even though species diversity of the two groups has opposing trends, indicating that the macroevolutionary size change is an active response to selection pressure rather than a passive response to changes in diversity. The changes in the median size of dinoflagellate cysts are highly correlated with both deep ocean temperatures and the thermal gradient between the surface and deep waters, indicating the magnitude and frequency of nutrient availability may have acted as a selective factor in the macroevolution of cell size in the plankton. Our results suggest that climate, because it affects stratification in the ocean, is a universal abiotic driver that has been responsible for macroevolutionary changes in the size structure of marine planktonic communities over the past 65 million years of Earth's history.

Phylogenetic analysis of 16S rRNA revealed that 2 of these strains are most closely related to previously identified algicidal bacteria, indicating potentially similar mechanisms of interaction. Long-term (2 wk) co-incubations of algae and bacteria under a 12:12 h light:dark cycle resulted in decreased algal cell abundances (compared to bacteria-free controls) followed by temporary cyst formation. Short-term incubations in continuous light resulted in no apparent effects of the bacteria over 2 d, but incubations in continuous darkness resulted in algal ecdysis after 24 h followed by significant decreases in total algal cell abundances after 52 h compared to controls without algicidal bacteria. We also showed that ecdysis resulted in the removal of bacteria attached to the surface of the algal cells, demonstrating a potentially direct benefit to the algae if the bacteria are harmful. We further suggest that negative interactions of bacteria on phytoplankton may be enhanced in the absence of light.	[Mayali, Xavier; Franks, Peter J.

Microbial community diversity in the phycosphere of natural populations of the toxic alga, <i>Alexandrium fundyense</i>	ENVIRONMENTAL MICROBIOLOGY			English	Article							CYST FORMATION; HIROSHIMA BAY; PHYLOGENETIC DIVERSITY; SEQUENCE-ANALYSIS; NORTH-ATLANTIC; MARINE WATERS; WESTERN GULF; BACTERIA; BLOOM; DIMETHYLSULFONIOPROPIONATE	The dinoflagellate Alexandrium fundyense is the major causative organism of paralytic shellfish poisoning in the Gulf of Maine. While laboratory studies have shown that A. fundyense population dynamics can be affected dramatically by co-occurring bacteria, little is known about these interactions in nature. Because A. fundyense is typically a minor Gulf of Maine phytoplankton community member, analyses of the bulk community cannot be used to address bacterium-A. fundyense associations. Therefore, an immunomagnetic bead method was used to selectively capture A. fundyense cells, and the bacteria attached to them, from complex natural samples. Bulk particle-associated and free-living bacterial communities were collected simultaneously. DNA was extracted from all sample types and subjected to 16S rRNA gene fragment amplification, denaturing gradient gel electrophoresis (DGGE) and sequence analysis. Ordination analysis of DGGE profiles confirmed that A. fundyense-associated bacteria community profiles were distinct from bulk bacterial community profiles, indicating selection of specific phylotypes in the A. fundyense phycosphere. Phylogenetic analyses confirmed that Alexandrium-associates were distinct from bulk particle-associated bacteria and that they included a greater prevalence and broader diversity of Gammaproteobacteria than previously thought to be associated with toxic algae. Phylogenetic groups known to be associated with dinoflagellates were also found, including members of the families Alteromonadaceae, Pseudoalteromonadaceae, Rhodobacteraceae and Flavobacteraceae.

Blooms of the toxic dinoflagellate <i>Alexandrium fundyense</i> in the western Gulf of Maine in 1993 and 1994:: A comparative modeling study	CONTINENTAL SHELF RESEARCH			English	Article						red tides; algal blooms; harmful algal blooms; modeling; paralytic shellfish poisoning	GONYAULAX-TAMARENSIS; MARINE-PHYTOPLANKTON; COASTAL CURRENT; INTERANNUAL VARIABILITY; GROWTH; CIRCULATION; TRANSPORT; SALINITY; DYNAMICS; OCEAN	Blooms of the toxic dinoflagellate Alexandrium fundyense commonly occur in the western Gulf of Maine but the amount of toxin observed in coastal shellfish is highly variable. In this study, a coupled physical-biological model is used to investigate the dynamics underlying the observed A. fundyense abundance and shellfish toxicity in 1993 (a high toxicity year) and 1994 (low toxicity year). The physical model simulates the spring circulation, while the biological model estimates the germination and population dynamics of A. fundyense based on laboratory and field data. The model captures the large-scale aspects of the initiation and development of A. fundyense blooms during both years, but small-scale patchiness and the dynamics of bloom termination remain problematic. In both cases, the germination of resting cysts accounts for the magnitude of A. fundyense populations early in the spring. Simulations with low net A. fundyense growth rates capture the mean observed concentration during the bloom peak, which is of similar magnitude during both years. There is little evidence that large-scale changes in biological dynamics between 1993 and 1994 were a primary driver of the differences in shellfish toxicity. Results instead suggest that the persistent southwesterly flow of the western Maine Coastal Current led to A. fundyense populations of similar alongshore extent by late May of both years. This period coincides with peak cell abundance in the region. Variations in wind forcing (downwelling favorable in 1993, upwelling favorable in 1994) and subsequent cell transport (inshore in 1993, offshore in 1994) in early June then provides a plausible explanation for the dramatic mid-June differences in shellfish toxicity throughout the western Gulf of Maine.

Such kinds of cysts were collected in the East China Sea and were allowed to germinate. The cyst of Ensiculifera sp. is spherical with a diameter of 22 mu m. The cyst consists of two layers and is full of greenish granules, with a bright red body inside. The cyst wall is covered with short organic spines (2 mu m long). The cell of Ensiculifera sp. comprises a conical epitheca and a rounded hypotheca, with the dimension of 17.7 mu m long and 12.5 mu m wide on the average. The plate pattern is po, x, 4', 3a, 7 '', 5c, 4s, 5'''P, 2''''. The cysts of Fragilidium mexicanum Balech are spherical with the diameter ranging from 54-60 mu m. They are full of pale white granules and brown protoplasm, with a bright yellow body present. The archeopyle is spherical. The cells of F mexicanum are 45.3 mu m long and 42.8 mu m wide, with the plate formula of po, 5', 7 '', 10c, 7s, 7''' 2'''', 1P. The cyst of Fragilidium sp. is also spherical with a diameter of 45 mu m, which is similar to that of F. mexicanum except that the yellow body is not present. The cells of Fragilidium sp. are 41.6 pin long and 35.3 mu m wide with the plate formula of po, 5', 7 '', 7''', 2'''', 1P. The Internal Transcribed Spacers (ITS) of Ensiculifera sp. and the small subunit (18S) rDNA of Fragilidium spp. were amplified and sequenced. Their phylogenetic positions agree with the morphological taxonomy.

Ruiz			The dinoflagellate <i>Alexandrium minutum</i> in Cape Town harbour (South Africa):: Bloom characteristics, phylogenetic analysis and toxin composition	HARMFUL ALGAE			English	Article						Alexandrium minutum; harbour bloom; phylogenetics; cysts; toxins	ISOTOPE-DILUTION MODELS; ENVIRONMENTAL-FACTORS; GONYAULAX-TAMARENSIS; CYST PRODUCTION; DINOPHYCEAE; NITROGEN; PHOSPHORUS; AMMONIUM; GROWTH; ENCYSTMENT	A novel bloom of Alexandrium minutum occurred in an inner basin of the Cape Town harbour from November 2003 to February 2004. Cellular concentrations reached a maximum of 1.4 x 10(8) cells l(-1) during the mid-December period with corresponding chlorophyll a concentrations of 243 mg m(-3). Primary productivity measurements conducted during the latter part of the bloom revealed a maximum assimilation number of 11.17 mg C mg Chl a(-1) h(-1) during the middle of the day. Productivity during this post-peak period was sustained largely by the reduced nitrogen species NH4 and urea (96%) as measured using N-15 tracer techniques. The large subunit ribosomal DNA sequence of A. minutum isolates from Cape Town harbour was identical to conspecifics collected in Western Europe and in Australia. The composition of tetrahydropurine neurotoxins associated with paralytic shellfish poisoning (PSP) was limited to gonyautoxins (GTX1-GTX4). This profile combined with evidence of a low toxin cell quota (1.5 fmol GTX cell(-1)) supports a close association of this taxon with other members of the A. minutum species complex, particularly from Europe. Toxin analysis from black mussels collected during this bloom indicated that the accumulated PSP toxins originated from A. minutum and not from Alexandrium catenella as is most often the case along the South African coast.

Towards an optimal sampling strategy for <i>Alexandrium catenella</i> (Dinophyceae) benthic resting cysts	HARMFUL ALGAE			English	Article						Alexandrium catenella; toxic dinoflagellate; resting cyst; optimum sample size; spatial distribution; vertical profiles	DINOFLAGELLATE CYSTS; SURFACE SEDIMENTS; DISPERSION STATISTICS; ENVIRONMENTAL-FACTORS; MARINE-SEDIMENTS; WEST-COAST; BAY; BLOOM; GERMINATION; DYNAMICS	The study proposes methodological developments to optimize sampling strategy of resting cysts of Alexandrium catenella to estimate their abundance with a predefined error. This work also aims to provide information on spatial distribution of resting cysts in sediments. The distribution mode of A. catenella resting cysts related to the abundance variability was studied through sediment cores sampling on four different spatial scales and using Ludox CLX gradient density method. The quantification method underestimates by a factor of 2 the resting cysts abundance in one gram of sediment. Application of Taylor's power law allowed us to define a compromise between sampling effort and abundance estimation error. In the case of A. catenella resting cysts from Thau lagoon, the optimal sampling strategy consists of sampling 10 stations on a surface of 2 km(2) for a given coefficient of variability (C) of 15%, sampling 3 sediment cores at each station (C = 30%) and counting only one replicate by core (C = 18%). Results related to the application of Taylor's power law are closely dependent on resting cyst density and aggregation in a given sediment. In our area, A. catenella resting cysts are mainly observed in the upper 3 cm of sediment. Horizontally, their heterogeneity is lower on 10 cm(2) surface and tends to stabilize itself beyond a surface of 10 m(2). Each author has to carry out this pre-sampling effort for his own resting cysts-fonning species, in his own area, in order to increase accuracy of resting cyst mapping. (C) 2007 Elsevier B.V.

F.; Schmidt, Martin			Assessing environmental control on dinoflagellate cyst distribution in surface sediments of the Benguela upwelling region (eastern South Atlantic)	LIMNOLOGY AND OCEANOGRAPHY			English	Article							ORGANIC-MATTER; RED TIDE; DEEP-SEA; PRESERVATION; OCEAN; PRODUCTIVITY; SYSTEM; NORTH; ASSEMBLAGES; POPULATIONS	Organic-walled dinoflagellate cyst assemblages in surface sediments of the Benguela Current Upwelling System (eastern South Atlantic) show geographic patterns that cannot entirely originate from cyst production or transport. Aimed at answering how far these variations are due to taphonomic control, this study investigated a possible correlation with the changes in bottom-water oxygen concentrations typifying this region. Based on 36 samples, multivariate statistics were used to analyze community variability with respect to bottom-water oxygen concentration, temperature, salinity, nutrient content, chlorophyll a (Chl a) concentration, the organic carbon content of surface sediments, and a measure of water column stratification. Determined relationships to salinity, nutrient supply, nutrition, and environmental steadiness point out the requirements for dinoflagellate cyst production, while cross-shelf transport processes could have introduced variability prior to burial of cysts in surface sediments. The offshore decrease in the relative abundance of protoperidinacean cyst types was consistent with their lower preservation potential under oxygenated conditions and coincided with a change in assemblage composition toward oxidation resistant species. On elimination of covariation, bottom-water oxygenation was significantly related to this pattern and determined together with seasonal salinity, Chl a, and annual phosphate concentration, the parameter combination best explaining community variability. These results suggest that postdepositional degradation of peridinioid dinoflagellate cysts would partly explain the onshore-offshore gradient in species distributions and could be responsible for more variability in assemblage compositions than is presently acknowledged.

Morphology and phylogeny of <i>Gymnodinium trapeziforme</i> sp nov (Dinophyceae):: a new dinoflagellate from the southeast coast of Iran that forms microreticulate resting cysts	PHYCOLOGIA			English	Article						dinollagellate; gymnodinium; systematics; taxonomy; DNA; LSU-rDNA; microreticulate; resting cyst; Iran; Oman sea	RECENT MARINE-SEDIMENTS; CATENATUM-LIKE CYSTS; COMB. NOV; ULTRASTRUCTURE; TASMANIA; REPRODUCTION; AUREOLUM; WATERS; BASIN; SEA	A new gymnodinioid dinoflagellate, Gymnodinium trapeziforme sp. nov. is described from laboratory cultures established by germination of microreticulate resting cysts collected along the southeast coast of Iran bordering the northern Oman Sea. The vegetative cells are small, biconical to ovoid, with a horseshoe-shaped apical groove that encircles the apex in an anticlockwise direction. Cells have a large tear-shaped nucleus positioned in the right side of the cell that extends from the epicone to the hypocone. Cells of G. trapeziforme can be clearly differentiated from the three other microreticulate cyst-forming gymnodinioids, Gymnodinium catenatum, Gymnodinium nolleri, and Gymnodinium microreticulatum by the shape and position of the nucleus. Cultures established from resting cysts do not produce detectable saxitoxin. The resting cysts of G. trapeziforme are unique in being cubic-trapezoidal in shape with a cyst wall colour that is pale purple-brown, most similar in colour to cysts of G. microreticulatum Botch & Hallegraeff. Comparisons of partial large subunit ribosomal RNA gene sequences demonstrate that G. trapeziforme is allied with, but distinct from (> 12.4%, sequence divergence) the other microreticulate cyst-forming gymnodinioid species.

Intrinsic potency of synthetically prepared brevetoxin cysteine metabolites BTX-B2 and desoxyBTX-B2	TOXICON			English	Article						brevetoxin; marine toxins; Karenia brevis; neurotoxic shellfish poisoning; voltage-gated sodium channel; cytotoxicity assay; radioimmunoassay; receptor-binding assay	OYSTER CRASSOSTREA-VIRGINICA; SENSITIVE SODIUM-CHANNELS; KARENIA-BREVIS CULTURES; RED-TIDE; PTYCHODISCUS-BREVIS; NEW-ZEALAND; AUSTROVENUS-STUTCHBURYI; CONTROLLED EXPOSURES; GREENSHELL MUSSELS; PERNA-CANALICULUS	In mammals and shellfish, brevetoxins produced by the dinoflagellate Karenia brevis are rapidly metabolized to cysteine conjugates. These metabolites identified by mass spectrometry are produced in abundance in mammals and are potentially major bioactive products for intoxication. They are also abundant metabolites in shellfish where they are, in contrast to mammals, retained for prolonged periods, posing a potential threat to shellfish consumers. In this work, we analyze the intrinsic potency of the semi-synthetic cysteine brevetoxin sulfoxide (BTX-B2) and the cysteine brevetoxin (desoxyBTX-B2), each confirmed for purity by LC-MS and NMR techniques, on receptor site 5 of the voltage-gated sodium channels (VGSCs) in brain, heart and skeletal muscle. We show that both brevetoxin conjugates compete with the tritiated reduced parent brevetoxin ([H-3]PbTx-3) in rat brain membrane preparations and in HEK cells expressing skeletal muscle or cardiac VGSC, albeit, with 8-16-fold lower affinity than the PbTx-3. On neuroblastoma cell assays we show a 3-fold reduction in cytotoxic potency for BTX-B2 relative to PbTx-3, and an 8-fold reduction for desoxyBTX-B2. In conclusion, the major transformation product of brevetoxin observed in diverse species through cysteine adduction and oxidation leads to metabolites with reduced potency on brain, skeletal muscle and heart cells.

Effect of biotic and abiotic factors on in vitro proliferation, encystment, and excystment of <i>Pfiesteria piscicida</i>	APPLIED AND ENVIRONMENTAL MICROBIOLOGY			English	Article							DINOFLAGELLATE HETEROCAPSA-CIRCULARISQUAMA; PHOSPHORUS-LIMITED CULTURES; TOXIC DINOFLAGELLATE; GONYAULAX-TAMARENSIS; CYST GERMINATION; GROWTH-RATES; LIFE-CYCLE; ENVIRONMENTAL EXPOSURE; FORMING DINOFLAGELLATE; ICHTHYOCIDAL ACTIVITY	Pfiesteria spp. are mixotrophic armored dinoflagellates populating the Atlantic coastal waters of the United States. They have been a focus of intense research due to their reported association with several fish mortality events. We have now used a clonal culture of Pfiesteria piscicida and several new environmental isolates to describe growth characteristics, feeding, and factors contributing to the encystment and germination of the organism in both laboratory and environmental samples. We also discuss applied methods of detection of the different morphological forms of Pfiesteria in environmental samples. In summary, Pfiesteria, when grown with its algal prey, Rhodomonas sp., presents a typical growth curve with lag, exponential, and stationary phases, followed by encystment. The doubling time in exponential phase is about 12. h. The profiles of proliferation under a standard light cycle and in the dark were similar, although the peak cell densities were markedly lower when cells were grown in the dark. The addition of urea, chicken manure, and soil extracts did not enhance Pfiesteria proliferation, but crude unfiltered spent aquarium water did. Under conditions of food deprivation or cold (4 degrees C), Pfiesteria readily formed harvestable cysts that were further analyzed by PCR and scanning electron microscopy. The germination of Pfiesteria cysts in environmental sediment was enhanced by the presence of live fish: dinospores could be detected 13 to 15 days earlier and reached 5- to 10-times-higher peak cell densities with live fish than with artificial seawater or f/2 medium alone. The addition of ammonia, urea, nitrate, phosphate, or surprisingly, spent fish aquarium water had no effect.

J	Ki, JS; Han, MS				ki, Jang-Seu; Han, Myung-Soo			Rapid molecular identification of the harmful freshwater dinoflagellate <i>Peridinium</i> in various life stages using genus-specific single-cell PCR	JOURNAL OF APPLIED PHYCOLOGY			English	Article						dinoflagellate cyst; planozygote; rDNA	DINOPHYCEAE; CYSTS	Cysts of the freshwater dinoflagellate Peridinium are typically different from vegetative cells in shape and remain largely undescribed. Molecular discrimination of such cysts would be useful to a number of research disciplines. A reliable method for the amplification of ribosomal DNA (rDNA) from Peridinium at different life stages is described. This genotyping strategy relies on whole cell PCR using Peridinium-specific primers designed from available 18S rDNA sequences. Here, we demonstrate the effectiveness of Peridinium-specific PCR for the rapid molecular identification of Peridinium cells in various life stages such as vegetative, planozygote, hypnozygote and cyst.

Palatability and fatality of the dinoflagellate <i>Prorocentrum lima</i> to <i>Artemia salina</i>	JOURNAL OF APPLIED PHYCOLOGY			English	Article						artemia; cell-free culture medium; nauplii survivorship; Prorocentrum lima	GRAZING RESPONSES; COPEPODS; TOXICITY; ZOOPLANKTON; DINOPHYCEAE; SURVIVAL; MEDIA; ACID; FISH	Prorocentrum lima is a toxic alga that produces both intra-cellular and extra-cellular toxins, including okadaic acid (OA) and dinophysistoxins (DTXs). Nauplii of the brine shrimp Artemia salina were exposed to both the cell and cell-free culture medium of P. lima in order to test the hypotheses that the extra-cellular medium is toxic to brine shrimp and that the P. lima cell is palatable but fatal to it. Artemia cysts incubated in the cell-free medium hatched, but mortalities were recorded for nauplii that hatched in, and metanuaplii exposed to, test solutions (autoclaved filtered seawater + cell-free medium) that contained at least 50% of the cell-free medium. Animals exposed to cells of P. lima readily fed on the cells. Some, especially among the Day 1 nauplii, ingested only one cell before dying, while others ingested more than one cell, up to six cells in the case of Day 3 nauplii, before dying. Day 3 nauplii were readily and heavily impacted by the P. lima cells. Survival analysis was used to evaluate survivorship of Day 1 to Day 3 nauplii exposed to cells of P. lima. Estimates were made of tD50s for the different age groups. Comparisons of the tD50s showed that the tD50s for Day 1 and Day 2 nauplii did not vary significantly, but they each varied significantly from the tD50 for the Day 3 nauplii. The possible ecological implications of the findings are discussed.

Due to the importance of discriminating between HAB-forming species, we compared the undescribed life-cycle pattern of Alexandrium tamutum Montresor, Beran et U. John and of its toxic relative Alexandrium minutum Halim. Sexual stages, asexual and sexual division, mating type, and nuclear morphology were studied in both species. Sexual cysts are known to be morphologically identical. However, the relative size of the U-shaped nucleus may be used to differentiate between the cysts of these species since DNA packaging in the resting cysts was lower in A. tamutum than in A. minutum, species in which the planozygote nucleus was reduced to half its volume prior to encystment. The dormancy period of the cysts was < 20 d for A. tamutum, but longer than 1 month for A. minutum. In both species, cyst appearance needed to be explained by the existence of more than two sexual types (+/-), which indicates a complex heterothallic mating type. However, planozygotes of both species may divide instead of encysting. This characteristic was used for nutritional and heritage studies. Isolated planozygotes of both species encysted in larger percentages in medium deficient in both nitrates and phosphates (L/15) than in medium without phosphates added (L-P), a medium in which most planozygotes neither divide nor encyst. Parental strains of A. minutum with and without the ventral pore formed planozygotes and, later, offspring with the ventral pore, although apparently smaller than usual. A synchronization-flow cytometry method for discriminating diploids formed by sexual fusion (planozygotes) from cells with 2C DNA content resulting from self-duplication of DNA (dividing cells) was described. The results indicated that the maximum percentage of A. minutum planozygotes (20%) was achieved only 3 to 5 d after crossing the parental strains, and that light might not be needed for the sexual fusion and formation of planozygotes.

J	Novichkova, EA; Polyakova, EI				Novichkova, E. A.; Polyakova, E. I.			Dinoflagellate cysts in the surface sediments of the White Sea	OCEANOLOGY			English	Article							ARCTIC-OCEAN; ASSEMBLAGES; INDICATORS; NUTRIENTS; ATLANTIC; LAPTEV; WATER	Dinoflagellate cysts were studied in 42 samples from the surface sediments of the White Sea. The total concentration of dinocysts varies from single cysts to 25000 cyst/g of dry sediments, which reflects the biological productivity in the White Sea waters and the regional particular features of the sedimentation processes. The highest concentrations are observed in silts; they are related to the regions of propagation of the highly productive Barents Sea waters in the White Sea. Generally, the spatial distribution of dinocysts species in the surface sediments corresponds to the distribution of the major types of water masses in the White Sea. The cysts of the relatively warm-water species (Operculodinium centrocarpum, Spiniferites sp.) of North Atlantic origin that dominate in the sediments indicate an intensive intrusion of the Barents Sea water masses to the White Sea along with hydrological dwelling conditions in the White Sea favorable for the development of these species during their vegetation period. The cold-water dinocyst assemblage (Islandinium minutum, Polykrikos sp.) is rather strictly confined to the inner parts of shallow-water bays, firstly, those adjacent to the Onega and Severnaya Dvina river mouths.

Larval <i>Crassostrea</i> bivalve and <i>Artemia</i> brine shrimp bioassays to assess toxicity and micropredation by the heterotrophic dinoflagellates <i>Cryptoperidiniopsis brodyi</i> and <i>Pfiesteria piscicida</i> from Australian waters	JOURNAL OF PLANKTON RESEARCH			English	Article							ESTUARINE DINOFLAGELLATE; LIFE-CYCLE; PROTOGONYAULAX-TAMARENSIS; INVERTEBRATE LARVAE; ATLANTIC MENHADEN; FISH BIOASSAY; DINOPHYCEAE; BEHAVIOR; SHUMWAYAE; PREY	The capability of the heterotrophic Australian marine dinoflagellates Cryptoperidiniopsis brodyi and Pfiesteria piscicida to impact on larval Pacific oyster (Crassostrea gigas) and brine shrimp) (Artemia salina) nauplii was investigated. An attractant response of the heterotrophs toward actively swarming Artemia was not observed and no mortality occurred. In contrast, the dinoflagellates became active and exhibited attacking) behavior toward planktonic oyster larvae (below 1 mm size) within a few seconds. The oyster larvae survived 2500 cells mL(-1) for 2 days, but mortality increased to 82-88% by day 12. Aqueous dinoflagellate cell extracts collected from. the bioassay that induced oyster kills were tested in a further larval bivalve bioassay but no mortality was observed. Oyster over 2 mm in size survived the physical attack by the heterotrophs and remained alive during the bioassay period. Changes in zoospore and cyst abundances in the presence of oyster larvae were also documented. More actively swarming zoospores and 2.5-fold higher cell numbers were produced in the presence of oysters compared to control cultures. These results indicate that mortalities of the planktonic larvae can be induced by micro-predatory feeding behavior of C. brodyi and P. piscicida.

Morphogenetic and toxin composition variability of <i>Alexandrium tamarense</i> (Dinophyceae) from the east coast of Russia	PHYCOLOGIA			English	Article						Alexandrium tamarense; distribution; far eastern seas of Russia; LSU rRNA; morphology; PSP; toxicity	DINOFLAGELLATE PROTOGONYAULAX-TAMARENSIS; NORTH-AMERICAN; SPECIES COMPLEX; RED TIDE; POPULATIONS; GONYAULAX; WATERS; MORPHOLOGY; STRAINS	Twenty-seven clones were established from elongate Alexandrium sp. cysts collected in six regions along the Russian Pacific coast. All isolates were identified as Alexandrium tamarense via detailed epifluoresence microscopy of thecal plates. Morphological differences of both cultured and wild cells from the study regions mainly occurred in the shape of the cell (length/width ratio), degree of development of the sulcal list, and the shape of the posterior sulcal (S.p.) and second antapical (2) plates. Cells were divided into two cell types: 'short' (isodiametrical or wide) and 'tall'. Each cell type exhibits specific features of tabulation, mainly the shape of the S.p. and 2 plates and was dominant in each particular region of the study. The short type, with a wide S.p. and reduced length in the dorsoventral 2 plates, was characteristic of A. tamarense from Primorye and southern Sakhalin Island. The tall cells, i.e., with cell length exceeding width, and having and elongate S.p. and dorsoventrally elongate 2 plates, prevailed in Avachinskaya Guba Inlet and in the Bering Sea. The differences reported here between the two types are within the range of morphological variability of A. tamarense sensu Balech, 1995. The D1-D2 fragment of the large subunit nuclear ribosomal DNA was analyzed for 24 clones. Alexandrium tamarense from the Russian Pacific coast compose three genetically distinct populations that correspond to the Japanese temperate Asian, eastern North American, and western North American ribotypes of the 'tamarensis' complex. The presence and distribution of eastern and western North American ribotypes along the Russian Pacific coast suggest that dispersion to the temperate Asian region occurred long ago via natural cur-rents and processes, and not through human-mediated introductions, as has been proposed. No strict correlation was observed between different morphological types of cells and ribotypes. High-performance liquid chromatography toxin analyses showed that all isolates were toxic and demonstrated variability in toxin content and composition among different populations. These data document the significant and previously uncharacterized risk of shellfish contamination with paralytic shellfish poisoning toxins from blooms of A. tamarense in Russian marine waters.

Comparative morphological analyses and sequencing of the rDNA-ITS and 5.8S rDNA show that the new species, Scrippsiella irregularis sp. nov., is allied to but distinct from Scrippsiella precaria and S. ramonii. Vegetative cells of the new species are similar in size, shape, and plate tabulation to S. precaria; however, the cingulum is equatorially placed, the nucleus is in the hypocone, and the second anterior intercalary plate is larger and rounded rather than diamond-shaped. The resting cysts isolated from sediments and produced in laboratory cultures are spherical to ovoid with numerous pointed to slightly capitate calcareous processes.

Phytoplankton and bacterial assemblages in ballast water of US military ships as a function of port of origin, voyage time, and ocean exchange practices	HARMFUL ALGAE			English	Review						bacteria; ballast water exchange; harmful algae; phytoplankton; ship; transport	RIBOSOMAL-RNA GENES; 18S RDNA SEQUENCES; PCR AMPLIFICATION; PFIESTERIA-PISCICIDA; DINOFLAGELLATE CYSTS; MARINE COMMUNITIES; PSEUDOMONAS-PUTIDA; ESCHERICHIA-COLI; GLOBAL TRANSPORT; RAPID DETECTION	We characterized the physical/chemical conditions and the algal and bacterial assemblages in ballast water from 62 ballast tanks aboard 28 ships operated by the U.S. Military Sealift Command and the Maritime Administration, sampled at 9 ports on the U.S. West Coast and 4 ports on the U.S. East Coast. The ballast tank waters had been held for 2-176 days, and 90% of the tanks had undergone ballast exchange with open ocean waters. Phytoplankton abundance was highly variable (grand mean for all tanks, 3.21 x 10(4) viable cells m(-3); median, 7.9 x 10(3) cells m(-3)) and was unrelated to physical/chemical parameters, except for a positive relationship between centric diatom abundance and nitrate concentration. A total of 100 phytoplankton species were identified from the ballast tanks, including 23 potentially harmful taxa (e.g. Chaetoceros concavicornis, Dinophysis acuminata, Gambierdiscus toxicus, Heterosigma akashiwo, Karlodinium veneficum, Prorocentrunt minimum, Pseudo-nitzschia multiseries). Assemblages were dominated by chain-forming diatoms and dinoflagellates, and viable organisms comprised about half of the total cells. Species richness was higher in ballast tanks with coastal water, and in tanks containing Atlantic or Pacific Ocean source waters rather than Indian Ocean water. Total and viable phytoplankton numbers decreased with age of water in the tanks. Diversity also generally decreased with water age, and tanks with ballast water age >33 days did not produce culturable phytoplankton. Abundance was significantly higher in tanks with recently added coastal water than in tanks without coastal sources, but highly variable in waters held less than 30 days. Bacterial abundance was significantly lower in ballast tanks with Atlantic than Pacific Ocean source water, but otherwise was surprisingly consistent among ballast tanks (overall mean across all tanks, 3.13 +/- 1.27 x 10(11) cells m(-3); median, 2.79 x 10(11) cells m(-3)) and was unrelated to vessel type, exchange status, age of water, environmental conditions measured, or phytoplankton abundance. At least one of four pathogenic eubacteria (Listeria monocytogenes, Escherichia coli, Mycobacterium spp., Pseudomonas aeruginosa) was detected in 48% of the ballast tanks, but toxigenic strains of Vibrio cholerae were not detected. For ships with tanks of similar ballasting history, the largest source of variation in phytoplankton and bacteria abundance was among ships; for ships with tanks of differing ballasting histories, and for all ships/tanks considered collectively, the largest source of variation was within ships. Significant differences in phytoplankton abundance, but not bacterial abundance, sometimes occurred between paired tanks with similar ballasting history; hence, for regulatory purposes phytoplankton abundance cannot be estimated from single tanks only. Most tanks (94%) had adequate records to determine the source locations and age of the ballast water and, as mentioned, 90% had had ballast exchange with open-ocean waters. Although additional data are needed from sediments that can accumulate at the bottom of ballast tanks, the data from this water-column study indicate that in general, U.S. Department of Defense (DoD) ships are well managed to minimize the risk for introduction of harmful microbiota. Nevertheless, abundances of viable phytoplankton with maximum dimension >50 Rm exceeded proposed International Maritime Organization standards in 47% of the ballast tanks sampled. The data sugget that further treatment technologies and/or alternative management strategies will be necessary to enable DoD vessels to comply with proposed standards. (C) 2007 Elsevier B.V.

Dynamics and short-term survival of toxic cyanobacteria species in ballast water from NOBOB vessels transiting the Great Lakes - implications for HAB invasions	HARMFUL ALGAE			English	Article						ballast-water; molecular probes; viability; toxic cyanobacteria	REAL-TIME PCR; 16S RIBOSOMAL-RNA; PFIESTERIA-PISCICIDA; DINOFLAGELLATE CYSTS; CENTRAL CALIFORNIA; DNA EXTRACTION; SHIPS; TRANSPORT; MICROCYSTIS; BLOOM	We measured the presence, viability and potential toxicity of cyanobacteria in ships' ballast tanks during three domestic voyages through the North American Great Lakes. Using molecular methods, the toxin-producing forms of Microcystis and Anabaena were monitored in ballast water after ships' ballast tanks were filled at their first port of call, and at subsequent ports as ships transited the Great Lakes. Microcystis was detected in ballast water at intermediate and final ports of call in all three experiments, but the presence of Anabaena was more variable, suggesting low abundance or patchy distribution in ballast tanks. Both species were detected in ballast water up to I I days old. Detection of the microcystin synthetase gene, incyE, in ballast tanks indicated entrained cells were capable of producing microcystin, and further analyses of RNA indicated the toxin was being expressed by Microcystis, even after I I days in dark transit. These data demonstrate within-basin transport and delivery of planktonic harmful algal bloom (HAB) species to distant ports in the world's largest freshwater reservoir, with potential implications for drinking water quality. These implications are discussed with respect to management of microbial invasions and the fate of introduced phytoplankton in their receiving environment. (C) 2007 Elsevier B.V. All rights reserved.

Efficacy of three commercially available ballast water biocides against vegetative microalgae, dinoflagellate cysts and bacteria	HARMFUL ALGAE			English	Article						bacteria; ballast water treatment; chemical biocides; dinollagellate cysts	VIBRIO-CHOLERAE; SHIPS; TRANSPORT; VIABILITY; SURVIVAL	One proposed solution to the problem of ball ast-mediated aquatic invasions involves chemically treating ballast water to kill key target organisms. Here, we examine the efficacy of three commercially available ballast water biocides using vegetative microalgae, dinoflagellate resting cysts and bacteria as test organisms. Chemicals tested were the ballast water biocides SeaKleen (R) and Peraclean (R) Ocean, and the chlorine dioxide biocide Vibre (R). Results demonstrate that the applicability of each of the three chemical biocides as a routine ballast water treatment is limited by factors such as cost, biological effectiveness and possible residual toxicity of the discharged ballast water (assessed on the basis of impact on motility of vegetative marine microalgae). Of the three biocides tested, Peraclean (R) Ocean appears to hold the most potential; however its effectiveness in shipboard trials is yet to be proven. Peraclean (R) Ocean was biodegradable within 2-6 weeks (initial concentration of 200 ppm), could effectively inactivate resting cysts of the marine dinoflagellates Gymnodinium catenatuni, Alexandrium catenella and Protoceratium reticulatum at 400 ppm, could control bacterial growth of Escherichia coli, Staphylococcus aureus, Listeria innocua and Vibrio alginolyticus at 125-250 ppm, and could eliminate vegetative dinoflagellate cells at a concentration of 100 ppm. SeaKleen (R) eliminated vegetative microalgae at 2 ppm and could control resting cysts of the dinoflagellates G. catenatum and P. reticulatum at a concentration of 6 and 10 ppm, respectively, when exposed for a period of 2 weeks. SeaKleen (R) did not inactivate resting cysts of A. catenella at a concentration of 10 ppm and was found to degrade at a rate that could result in the discharge of residual toxic water into the marine environment. Together with the poor bactericidal properties of SeaKleen (R) (100-200 ppm required), this may limit the use of this biocide as a routine treatment option. Vibrex (R) is not a suitable ballast water treatment option due to the need for hydrochloric acid as an activator, however it was found to be the most effective against bacteria (complete inhibition at 15 ppm) indicating that onboard chlorine dioxide generators may provide an effective bacterial treatment option. The performance of these biocides was adversely influenced by a variety of factors including low water temperatures (6 degrees C compared to 17 degrees C, light versus dark conditions, and the presence of humus-rich seawater and ballast water sediments.

Reflections on the ballast water dispersal - harmful algal bloom paradigm	HARMFUL ALGAE			English	Review						ballast water; harmful algal blooms	DINOFLAGELLATE GYMNODINIUM-CATENATUM; ALEXANDRIUM-TAMARENSE DINOPHYCEAE; LONG-TERM PERSPECTIVE; MARINE-PHYTOPLANKTON; NORTH-ATLANTIC; BROWN TIDE; ECOLOGY; CYST; RAPHIDOPHYCEAE; CATENELLA	The ballast water dispersal-HAB paradigm, increasingly invoked circumstantially to explain puzzling and unaccountable HAB species outbreaks when lacking the multiple tests of confirmation recommended by Bolch and de Salas (2007), is evaluated. The types and examples of natural dispersions and taxon cycles are compared to exotic species bloom behavior linked to ballast water vectoring. The regional spreading, bloom behavior and disjunct distributions of the brown tide pelagophyte Aureococcus anophagefferens and the toxic dinoflagellate Gymnodinium cetenatum, attributed to ballast water vectoring, are used as representative examples to evaluate the general application of the ballast water-HAB paradigm and associated interpretative problems. Human-aided emigration has a seeding and colonization ecology that differs from bloom ecology. For self-sustaining blooms to occur, these two ecologies must be accommodated by habitat growth conditions. The three stages that a non-native species must pass through (pioneering, persistence, community entry) to achieve colonization, community maintenance, and to bloom, and the niche-related factors and role of habitat disturbance are discussed. The relevance of cryptic occurrences, cyst deposits, dormancy periods and bloom rhythms of HAB species to their blooms attributed to ballast water-assisted introductions is also sketched. The different forms of HAB species rarity, their impact on the ballast water dispersal-HAB paradigm, and the dispersion and blooms of specialist and generalist HAB species are discussed. The remarkable novel and, often, monospecific blooms of dinoflagellate HAB species are being paralleled by similar eruptive bloom behavior cutting across phylogenetic lines, and being found also in raphidophytes, haptophytes, diatoms, silicoflagellates, etc. These blooms cannot be explained only as seeding events. An ecological release of 'old barriers' appears to be occurring generally at coastal bloom sites, i.e. something significant is happening ecologically and embedded within the ballast water-HAB paradigm. There may be a relationship between Life Form type [Smayda, T.J., Reynolds, C.S., 2001. Community assembly in marine phytoplankton: application of recent models to harmful dinoflagellate blooms. J. Plankton Res. 23, 447-461] and mode of expatriation; HAB dinoflagellate species commonly reported to produce ballast water-assisted toxic blooms invariably are members of cyst-producing Life Forms IV, V, VI. Ballast water vectoring of Life Forms I, II, III is rarely reported, even though many produce cysts, and where their novel introductions do occur they are more likely to be ichthyotoxic, and vectored in shellfish stock consignments. The relevance of, and need to distinguish between morphospecies and their geographic/ribotype clades are discussed based on the Alexandrium tamarense/catenella/fundyense complex. Morphospecies-level ballast water dispersions are probably minor compared to the dispersal of the different ribotypes (toxic/non-toxic clades) making up HAB morphospecies; the redistribution and admixture of genotypes should be the focus. Ballast water-assisted expatriations impact the global occurrence of HABs through the direct transfer of previously absent species or introduction of genetic strains from the donor habitat that are ecologically favored over resident strains. The hybridization of species may be of potentially greater impact, resulting from the (1) mating of individuals from the donor and recipient habitats, or (2) through the interbreeding of strains introduced from to different donor sites into the recipient site, and whose progeny have greater ecological fitness than indigenous strains. Exceptional ecological changes of some sort appear to be occurring globally which, in combination with the genetically altered ecophysiological behavior of HAB species linked to ballast water dispersion and admixture, underpins the global HAB phenomenon. The impact of ballast water and shellfish transplantation on HABs and phytoplankton community ecology, generally, is considerably greater than the current focus on HAB species distributions, vectoring, and blooms. The methodological, investigative and conceptual potential of the ballast water-HAB paradigm should be exploited by developing a GEOHAB type intiative to advance quantification of global HAB ecology.

In Mexico a number of human fatalities and important economic losses have occurred in the last 30 years because of these events. There are about 70 species of planktonic and non-planktonic microalgae considered harmful in Mexican coasts. The most important toxin-producing species are the dinoflagellates Gymnodinium catenatuni and Pyrodinium bahamense var. compressum, in the Mexican Pacific, and Karenia brevis in the Gulf of Mexico, and consequently the poisonings documented in Mexico are Paralytic Shellfish Poisoning (PSP) and Neurotoxic Shellfish Poisoning (NSP). Although there is evidence that Amnesic Shellfish Poisoning (ASP), Diarrhetic Shellfish Poisoning (DSP) and Ciguatera Fish Poisoning (CFP) also occur in Mexico, these problems are reported less frequently. The type of phytoplankton and epiphytic microalgae, their toxins and harmful effects as well as current methodology used to study these phenomena are presented in this paper. As an experienced group of workers, we include descriptions of monitoring and mitigation programs, our proposals for collaborative projects and perspectives on future research.

In this study, we assessed the clearance rates of five species of bivalve mollusc-the northern bay scallop Argopecten irradians irradians, the eastern oyster Crassostrea virginica, the northern quahog Mercenaria mercennaria, the softshell clarn Mya arenaria, and the blue mussel Mytilus edulis-exposed for one hour to each of three harmful-algal strains: Prorocentrum minimum. Alexandrium fundyense, and Heterosigma akashiwo. Clearance rates of harmful-algal cells were compared with clearance rates of a benign microalga, Rhodomonas sp., and to a Mix of each harmful alga with Rhodomonas sp. Qualitative observations of valve closure and production of biodeposits were also assessed during the exposure experiments. Feces and pseudofeces were collected and observed with light and fluorescence microscopy for the presence or absence of intact, potentially-viable algal cells or temporary cysts. Results increase our understanding of the high variation between the different bivalve/harmful alga pairs. Responses of bivalve species to the different harmful algae were species-specific. but ill most cases indicated a preferential retention of harmful algal cells, probably based upon different characteristics of the algae. Each shellfish species also reacted differently to the harmful-algal exposures; several remained open; whereas, others, such as oysters exposed to the toxic raphiclophyte Heterosigma akashiwo, closed shells partially or totally. Similarly, production of feces and pseudofeces varied appreciably between the different bivalve/alga pairs; with the exception of softshell clams Mya arenaria, intact cells of most harmful-algal species tested were seen in biodeposits of the other four bivalve species. These results extend our understanding of the high species specificity in the interactions between harmful algae and bivalve molluscs and confirm that generalizations about feeding responses of bivalves to harmful algae cannot easily be made. In most cases. however. there was at least some ingestion of the harmful algae leading to exposure of soft tissues to the algal cells.

J	Rintala, JM; Spilling, K; Blomster, J				Rintala, Janne-Markus; Spilling, Kristian; Blomster, Jaanika			Temporary cyst enables long-term dark survival of <i>Scrippsiella hangoei</i> (Dinophyceae)	MARINE BIOLOGY			English	Article							RED-TIDE DINOFLAGELLATE; ALEXANDRIUM-TAYLORI DINOPHYCEAE; SEA-ICE; HETEROCAPSA-CIRCULARISQUAMA; GONYAULAX-EXCAVATA; LIFE-HISTORY; BALTIC SEA; DYNAMICS; RATES; NOV	We examined the dark survival strategy of the cold-water dinoflagellate Scrippsiella hangoei from the Baltic Sea. Cultures of S. hangoei were placed in dark and light and we followed the morphological developmentand, determined respiration rate and activity of extracellular leucine aminopeptidase (LAP). S. hangoei had LAP activity in the light, but not in the dark, suggesting that the degradation and use of organic substrates is not part of the dark survival strategy. After prolonged time in darkness (> 5 days), S. hangoei started to shed flagella and theca, and produced a previously undescribed temporary cyst. The transformation from vegetative cell into the temporary cyst initially increased respiration rate tenfold, but after the transformation the respiration rate decreased to almost undetectable levels. The presented temporary cyst enables survival through long periods in dark by reducing the respiration rate.

Two parasites were sampled from different localities. They are morphologically similar to each other and both resemble D. aspida. Nevertheless, two distinct sequences (7.6% divergence) were obtained from them. Phylogenetic trees inferred from maximum likelihood and maximum parsimony revealed that these two Duboscquella spp. sequences are enclosed in an environmental clade named Marine Alveolate Group 1. This clade consists of a large number of picoplanktonic organisms known only from environmental samples from various parts of the ocean worldwide, and which therefore lack clear characterization and identification. Here, we provide morphological and genetic characterization of these two Duboscquella genotypes included in this enigmatic clade. Duboscquella spp. produce a large number of small flagellated spores as dispersal agents and the presence of such small cells partially explains why the organisms related to these parasites have been detected within environmental genetic libraries, built from picoplanktonic size fractions of environmental samples. The huge diversity of the Marine Alveolate Group I and the finding that parasites from different marine protists belong to this lineage suggest that parasitism is a widespread and ecologically relevant phenomenon in the marine environment.

Pathology of <i>Hematodinium</i> infections in snow crabs (<i>Chionoecetes opilio</i>) from Newfoundland, Canada	JOURNAL OF INVERTEBRATE PATHOLOGY			English	Article						bitter crab disease; bitter crab syndrome; sporulation; gills; hepatopancreas; fishery; disease; crab	LOBSTER NEPHROPS-NORVEGICUS; PARASITIC DINOFLAGELLATE; NORWAY LOBSTER; CALLINECTES-SAPIDUS; BLUE CRABS; DISEASE; PEREZI; PREVALENCE; MORTALITY; SP.	Bitter crab disease (BCD) of snow crabs, Chionoecetes opilio, is caused by a parasitic dinoflagellate, Hematodinium sp. The disease has shown an alarming increase in prevalence in the commercial fishery in eastern and northeastern areas of Newfoundland and Labrador since it was first recorded there in the early 1990s. We documented histopathological alterations to the tissues in snow crabs with heavy infections of Honatodinium sp. and during sporulation of the parasite. Pressure necrosis was evident in the spongy connective tissues of the hepatopancreas and the blood vessels in most organs. In heavy infections, little remained of the spongy connective tissues around the hepatopancreas. Damage to the gills varied; in some cases it was severe, particularly during sporulation, involving apparent thinning of the cuticle, loss of epithelial cells, and fusion of the membranous layers of adjacent gill lamellae. Affected lamellae exhibited varying degrees of distention with a loss of trabecular cells, heitiocyte infiltrations, and swelling or "clubbing" along the distal margins. Large numbers of zoospores were located along the distal margins of affected lamellae suggesting that sporulation may cause a lysis or bursting of the thin lamellar cuticle, releasing spores. Pressure necrosis, due to the build up of high densities of parasites, was the primary histopathological alteration in most tissues. Hematodinium infections in the snow crab are chronic, long-term infections that end in host death, during sporulation of the parasite. (c) 2007 Elsevier Inc. All rights reserved.

J	Tillmann, U; John, U; Cembella, A				Tillmann, Urban; John, Uwe; Cembella, Allan			On the allelochemical potency of the marine dinoflagellate <i>Alexandrium ostenfeldii</i> against heterotrophic and autotrophic protists	JOURNAL OF PLANKTON RESEARCH			English	Article							PRYMNESIUM-PARVUM; CYST FORMATION; LIFE-HISTORY; FOOD UPTAKE; PHYTOPLANKTON; GROWTH; DINOPHYCEAE; ALLELOPATHY; HAPTOPHYTE; TAMARENSE	Three strains of the marine dinoflagellate Alexandrium ostenfeldii of different geographic origin were tested for their short-term deleterious effects on a diversity of marine protists. All A. ostenfeldii strains were capable of eliciting an apparent allelochernical response, but the various protistan target species were differentially affected. Protists that were negatively affected by exposure to cells of A. ostenfeldii and associated extracellular metabolites comprised both autotrophs (Rhodomonas sp., Dunaliella salina, Thalassiosira weissflogii) and heterotrophs (Oxyrrhis marina, Amphidinium crassum, Rimostrombidium caudatum). Observed effects included immobilisation (e.g. of O. marina), morphological changes (e.g. in D. salina) and/or aberrant behaviour (e.g. of R. caudatum), mainly as preliminary stages of cell lysis. Immobilization and lytic effects against O. marina were strongly dependent on A. ostenfeldii cell concentrations. Effects also differed substantially among strains and different batch cultures of the same strain. Values of EC50, defined as the A. ostenfeldii cell concentration causing lysis of 50% of O. marina cells, ranged from 0.3 to 1.9 x 10(3) mL(-1), depending on the A. ostenfeldii strain. The autotrophic dinoflagellate Scrippsiella trchoidea reacted to exposure to A. ostenfeldii cells by formation of temporay (ecdysal) cysts, whereas, in contrast, the flagellates Emaliania huxleyi and Prymnesium parvum and the ciliate Strombidium sp. were relatively refractory or even unaffected. As long as cells did not lyse, the fluorescence field of target autotrophs, estimated by pulse-amplitude modulation fluorometry, did not significantly change during the first 3 h of incubation, suggesting that allelochemicals produced by A. ostenfeldii caused no shortterm negative effects oil the photosynthetic apparatus. Overall, the allelochemical responses of target species showed no obvious relationship to cell quota or extracellular concentrations of either toxic inacrog,clic innues (spirolides) or letralydropurine neuroloxins (saxitoxill and analogues) produced by various strains of A. ostenfeldii. Instead, the poteng of A. osteifieldii, eliciting immobilization and lytic speries-specific responses in potential piedato?s and competitors, is consistent with the existence of all alleloclienzical meckam m unrelated to the bioactiviy of known phycoloxins of the genus A lexandrium.

The assemblages are taxonomically diverse, change over short stratigraphical intervals and are largely facies independent across marine basins. Affinities of this informal group of fossils to modern biota are poorly recognized or unknown, with the exception of only a few taxa. Morphological studies by use of transmitted light microscopy, geochemical analyses and other lines of evidence, suggest that some Precambrian acritarchs are related to algae (including prasinophytes, chlorophytes, and perhaps also dinoflagellates). Limitations in magnification and resolution using transmitted light microscopy may be relevant when assessing relationships to modern taxa. Scanning electron microscopy reveals details of morphology, microstructure and wall surface microelements, whereas transmission electron microscopy provides high-resolution images of the cell wall ultrastructure. In the light of previous ultrastructural studies it can be concluded that the division of acritarchs into leiospheres (unornamented) and acanthomorphs (ornamented) is entirely artificial and has no phylogenetic meaning. Examination of Gyalosphaeridium pulchrum using transmission electron microscopy reveals a vesicle wall with four distinct layers. This multilayered wall ultrastructure is broadly shared by a range of morphologically diverse acritarchs as well as some extant microalgae. The chemically resistant biopolymers forming the comparatively thick cell, together with the overall morphology support the interpretation of the microfossil as being in the resting stage in the life cycle. The set of features, morphological and ultrastructural, suggests closer relationship to green algae than dinoflagellates.

For accuracy it is essential to know how environmental parameters such as salinity, temperature and light influence dinoflagellate cyst production and morphology. Here the effect of variation in these parameters on production and morphology of Tuberculodinium vancampoae (the resting stage of Pyrophacus steinii) is detailed. Encystment of T vancampoae has been observed in all studied culture-experiments although only a few cysts are being formed at the limits of the temperature and salinity ranges (16.5 degrees C, 34.8 degrees C and 20, 45 psu) with highest cyst production at 27 degrees C and 35 psu. Temperature clearly affects cyst morphology; cysts formed in cultures grown at 16.5 degrees C and 34.8 degrees C possess small, flattened processes. These cysts are not completely absent in cultures grown at intermediate temperatures but form only a minor part of the association. In previous studies, salinity has been found to influence the cyst morphology of several dinoflagellate species but this seems not to be the case for T vancampoae. In this study there was no morphological variation related to salinity. High cyst production was observed in cultures grown under moderate to strong illumination but variation in illumination did not lead to morphological change. Our findings correspond to field observations where T. vancampoae has been observed in surface sediments of the sub-tropical to tropical regions characterised by mean sea surface temperatures between 12.7 degrees C and 29.5 degrees C, and sea surface salinities between 16.9 and 36.6 psu. In contrast to previous suggestions, T vancampoae appears to be heterothallic rather than homothallic. (c) 2006 Elsevier B.V. All rights reserved.

Monthly variations in cyst abundance and germination were tracked, and the effects of environmental factors (water temperature, pH, light and nutrients) on cyst germination were measured in the laboratory under ambient field conditions. During the bloom period, the cyst abundance of P. bipes in sediment samples fluctuated from 4 to 427 cells g(-1) (wet weight), and did not show season-dependent variation. During the same period, the number of vegetative cells of P. bipes in water samples varied from 0 to 9.79 x 10(2) ml(-1). Laboratory experiments revealed a maximum germination rate at 15.6 degrees C, and effective germination was observed at the naturally occurring pH values of 6 to 8, but not at pH 9. Cysts obtained from samples collected at higher temperatures (over 15 degrees C) germinated more quickly than those seeded at lower temperatures, while cysts collected in fall and early winter had a higher cumulative excystment rate than those collected in spring and summer, suggesting that cysts deposited at higher temperatures may act as a seed population for the winter blooms. These findings collectively indicate that germination of R bipes was mainly affected by water temperature and light intensity, and not nutrient levels and pH, and further show that the bloom of P. bipes observed in Juam Reservoir was likely promoted by the presence of sufficient nutrients, relatively high excystment rates and active growth occurring under low temperature conditions.

Responses of marine planktonic protists to amino acids:: feeding inhibition and swimming behavior in the ciliate <i>Favella</i> sp.	AQUATIC MICROBIAL ECOLOGY			English	Article						chemical ecology; signaling; ingestion; swimming behavior; ciliate; dinoflagellate	LIQUID-CHROMATOGRAPHIC DETERMINATION; DISSOLVED FREE; CHEMOSENSORY RESPONSES; CHEMICAL IDENTITY; SEA; DIMETHYLSULFONIOPROPIONATE; CHEMORECEPTION; PHYTOPLANKTON; PARAMECIUM; CHEMOTAXIS	Feeding rates of the tintinnid Favella sp. on the dinoflagellate Heterocapsa triquetra were inhibited by a number of dissolved free amino acids (DFAAs), with inhibition inversely proportional to the size of the amino acid side chain. The most inhibitory compounds (valine, cysteine, proline, alanine, and serine) reduced feeding to < 20 % of the control rate at a concentration of 20 mu M. Inhibition was dose-dependent, with a threshold of ca. 200 nM for proline, and did not depend on ciliate feeding history (well-fed versus starved). Inhibition occurred rapidly (<5 min after exposure) and was partially reversible upon removal of DFAAs. Detailed analysis of swimming did not reveal consistent changes in Favella sp. behavior upon exposure to inhibitory amino acids. In contrast to Favella sp., the heterotrophic dinoflagellate Gyrodinium dominans showed no feeding response to 20 mu M DFAAs, while the tintinnid Coxliella sp. exhibited reduced feeding (to approximately 50 % of control rates) in response to a subset of the amino acids active in Favella sp. Our findings, along with the prevalence of some inhibitory compounds at nM concentrations in natural waters, point to a signaling function for these amino acids. Feeding deterrence in Favella sp. is, however, contrary to the typical attractant or stimulatory role of DFAAs, which has been documented for organisms ranging from bacteria to metazoans. The information content of the signal remains unclear but may be related to detection of prey quality during suspension feeding by Favella sp.

J	Touzet, N; Franco, JM; Raine, R				Touzet, Nicolas; Franco, Jose M.; Raine, Robin			Characterization of nontoxic and toxin-producing strains of <i>Alexandrium minutum</i> (Dinophyceae) in Irish coastal waters	APPLIED AND ENVIRONMENTAL MICROBIOLOGY			English	Article							PARALYTIC SHELLFISH TOXINS; SP-NOV DINOPHYCEAE; GYMNODINIUM-CATENATUM; CATENELLA DINOPHYCEAE; PHYLOGENETIC ANALYSIS; SPECIES COMPLEX; RIBOSOMAL DNA; DINOFLAGELLATE; TAMARENSE; PHYTOPLANKTON	A comparative analysis of the morphology, toxin composition, and ribosomal DNA (rDNA) sequences was performed on a suite of clonal cultures of the potentially toxic dinoflagellate Alexandrium minutum Halim. These were established from resting cysts or vegetative cells isolated from sediment and water samples taken from the south and west coasts of Ireland. Results revealed that strains were indistinguishable, both morphologically and through the sequencing of the D1-D2 domain of the large subunit and the ITS1-5.8S-ITS2 regions of the rDNA. High-performance liquid chromatography fluorescence detection analysis, however, showed that only strains derived from retentive inlets on the southern Irish coast synthesized paralytic shellfish poisoning (PSP) toxins (GTX2 and GTX3), whereas all strains of A. minutum isolated from the west coast were nontoxic. Toxin analysis of net hauls, taken when A. minutum vegetative cells were in the water column, revealed no PSP toxins in samples from Killary Harbor (western coast), whereas GTX2 and GTX3 were detected in samples from Cork Harbor (southern coast). These results confirm the identity of A. minutum as the most probable causative organism for historical occurrences of contamination of shellfish with PSP toxins in Cork Harbor. Finally, random amplification of polymorphic DNA was carried out to determine the degree of polymorphism among strains. The analysis showed that all toxic strains from Cork Harbor clustered together and that a separate cluster grouped all nontoxic strains from the western coast.

After three rounds of subtractive PCR using cDNAs synthesized from mRNA of different matingtype cells, amplified PCR products were subcloned into a plasmid vector for construction of subtractive libraries. The dependence on mating type for different levels of accumulated mRNA in randomly selected library clones was confirmed by cDNA membrane array, amplified cDNA Southern blot and RNA dot blot analyses using DIG-labelled probes. One gene, AT4-3, showed a strong and mating-type-specific signal. As a result of sequencing of the complete nucleotide sequence of AT4-3, it was predicted that this gene encodes a protein with 131 amino acid residues. BLAST homology searches of nucleotide and deduced amino acid sequences showed no similarity to any known genes or proteins. The predicted amino acid sequence of AT4-3 has a presumptive N-terminal signal peptide for extracellular secretion, an N-linked glycosylation site and eight cysteine residues in half of the C-terminus. Although the function of this gene is unknown, these results provide the first evidence of intracellular variation between cells of different mating types in dinoflagellates.

J	Tang, YZ; Dobbs, FC				Tang, Ying Zhong; Dobbs, Fred C.			Green autofluorescence in dinoflagellates, diatoms, and other microalgae and its implications for vital staining and morphological studies	APPLIED AND ENVIRONMENTAL MICROBIOLOGY			English	Article							FLOW-CYTOMETRY; GYMNODINIUM-SANGUINEUM; AMPHIDINIUM-CARTERAE; CHESAPEAKE BAY; AMOEBOPHRYA SP; PHYTOPLANKTON; CYSTS; MAINE; CELLS; GULF	Green autofluorescence (GAF) has been described in the short flagellum of golden and brown algae, the stigma of Euglenophyceae, and cytoplasm of different life stages of dinoflagellates and is considered by some researchers a valuable taxonomic feature for dinoflagellates. In addition, green fluorescence staining has been widely proposed or adopted to measure cell viability (or physiological state) in areas such as apoptosis of phytoplankton, pollutant stresses on algae, metabolic activity of algae, and testing treatment technologies for ships' ballast water. This paper reports our epifluorescence microscopic observations and quantitative spectrometric measurements of GAIT in a broad phylogenetic range of microalgae. Our results demonstrate GAIT is a common feature of dinoflagellates, diatoms, green algae, cyanobacteria, and raphidophytes, occurs in the cytoplasm and particularly in eyespots, accumulation bodies, spines, and aerotopes, and is caused by molecules other than chlorophyll. GAF intensity increased with time after cell death or fixation and with excitation by blue or UV light and was affected by pH. GAF of microalgae may be only of limited value in taxonomy. It can be strong enough to interfere with the results of green fluorescence staining, particularly when stained samples are observed microscopically. GAF is useful, however, for microscopic study of algal morphology, especially to visualize cellular components such as eyespots, nucleus, aerotopes, spines, and chloroplasts. Furthermore, GAF can be used to visualize and enumerate dinoflagellate cysts in marine and estuarine sediments in the context of anticipating and monitoring harmful algal blooms and in tracking potentially harmful dinoflagellates transported in ships' ballast tanks.

This new device - the plankton emergence trap chamber (PET Chamber) - made of a clear acrylic plastic, consists of a top cylinder and a base plate attached to a bottom cylinder. After plugging the bottom cylinder with sediment collected from in situ sea bottom and filling the top cylinder with filtered seawater, the PET Chamber attached to a platform specially made for submerging the chambers is placed on the seafloor. An adequate area of the lateral side of the top cylinder is opened and covered by a plankton net (10 mu m mesh) to allow a water exchange between the inside and outside the cylinder. Thus, the PET Chamber can replicate in situ environments, such as temperature, irradiance and dissolved oxygen. Using the PET Chamber, we have succeeded in collecting germinating cells and estimating the germination flux (cells m(-2) day(-1)) of two dinoflagellates, Alexandrium catenella and Scrippsiella spp., in Ago Bay, Japan. Mircoscopic observations on the samples collected from July to October 2003 revealed fluxes of 124-2022 and 622-3732 cells m(-2) day(-1) in A. catenella and Scrippsiella spp., respectively. The data indicate that the new device can detect variations in the number of germinating cells of dinoflagellates. Its sampling ability, coupled with simplicity in deployment and retrieval procedures, can allow one to monitor the in situ emergence from/on the surface sediments of various organisms, that possess resting stages during their life histories, in various coastal waters.

It is necessary to identify A. tamarense and A. catenella cysts and to monitor their distribution in sediment in order to minimize the damages caused by PSP to the economy and food quality because cysts are the seed population for blooms caused by motile vegetative cells. In this study, we developed an efficient DNA extraction method from the natural cysts present in marine sediments after they were size fractionated with a plankton net (mesh size of 20-150 mu m). The 10-3000 cysts were added to the sediments collected from the Ariake Sea, and for which the primuline-staining method did not reveal any cysts. DNA was then extracted from each sample, and linear standard curves for A. tamarense and A. catenella cysts were obtained from the correlation between the Ct values by real-time PCR and the log of the initial densities of cysts. We monitored the A. tamarense and A. catenella cyst densities in the environmental samples. This assay was demonstrated to be a powerful tool for the identification, detection, and quantification of the cysts of the toxic dinoflagellates. (C) 2007 Elsevier B.V. All rights reserved.

J	Zonneveld, KAF; Bockelmann, F; Holzwarth, U				Zonneveld, Karin A. F.; Bockelmann, Frank; Holzwarth, Ulrike			Selective preservation of organic-walled dinoflagellate cysts as a tool to quantify past net primary production and bottom water oxygen concentrations	MARINE GEOLOGY			English	Article						dinoflagellate cysts; early diagenesis; organic matter; preservation; oxygen	BENGUELA UPWELLING SYSTEM; DIEL VERTICAL MIGRATION; SHORT-TERM VARIABILITY; SURFACE SEDIMENTS; ATMOSPHERIC CO2; ANCHOR STATION; PHYTOPLANKTON; OCEAN; NORTH; SCRIPPSIELLA	To understand the role of the ocean within the global carbon cycle, detailed information is required on key-processes within the marine carbon cycle; bio-production in the upper ocean, export of the produced material to the deep ocean and the storage of carbon in oceanic sediments. Quantification of these processes requires the separation of signals of net primary production and the rate of organic matter decay as reflected in fossil sediments. This study examines the large differences in degradation rates of organic-walled dinoflagellate cyst species to separate these degradation and productivity signals. For this, accumulation rates of cyst species known to be resistant (R-cysts) or sensitive (S-cysts) to aerobic degradation of 62 sites are compared to mean annual chlorophyll-a, sea-surface temperature, sea-surface salinity, nitrate and phosphate concentrations of the upper waters and deepwater oxygen concentrations. Furthermore, the degradation of sensitive cysts, as expressed by the degradation constant k and reaction time t, has been related to bottom water [O-2]. The studied sediments were taken from the Arabian Sea, north-western African Margin (North Atlantic), western-equatorial Atlantic Ocean/Caraibic, south-western African margin (South Atlantic) and Southern Ocean (Atlantic sector). Significant relationships are observed between (a) accumulation rates of R-cysts and upper water chlorophyll-a concentrations, (b) accumulation rates of S-cysts and bottom water [O-2] and (c) degradation rates of S-cysts (kt) and bottom water [O-2]. Relationships that are extremely weak or are clearly insignificant on all confidence intervals are between (1) S-cyst accumulation rates and chlorophyll-a concentrations, sea-surface temperature (SST), sea-surface salinity (SSS), phosphate concentrations (P) and nitrate concentrations (N), (2) between R-cyst accumulation rates and bottom water [O-2], SST, SSS, P and N, and between (3) kt and water depth. Co-variance is present between the parameters N and P, N, P and chlorophyll-a, oxygen and water depth.

Naphthoquinones as broad spectrum biocides for treatment of ship's ballast water: Toxicity to phytoplankton and bacteria	WATER RESEARCH			English	Article						ballast water; naphthoquinones; phytoplankton; bacteria; menadione	CYTOTOXICITY	Current UN International Maritime Organization legislation mandates the phased introduction of ballast water treatment technologies capable of complying with rigorous standards related to removal of waterborne organisms. Doubts concerning mechanical treatments at very high ballasting rates have renewed interest in chemical treatment for very large vessels. High removal rates for biota require broad spectrum biocides that are safe to transport and handle and pose no corrosion problems for ships' structure. The current study focuses on the naphthoquinone group of compounds and extends a previously reported set of screening bioassays with an investigation of the toxicity of four naphthoquinones to select protists and prokaryotes, representative of typical ballast water organisms. Vegetative dinoflagellate cysts exposed to 2.0 mg/L of the naphthoquinones juglone, plumbagin, menadione and naphthazarin showed varying degrees of chloroplast destruction, with menadione demonstrating the most potency. Laboratory and mesocosm exposures of various phytoplankton genera to menadione showed toxicity at 1.0 mg/L. Juglone demonstrated the most bactericidal activity as judged by a Deltatox assay (Vibrio fischeri) and by acridine orange counts of natural bacterial populations. (c) 2007 Elsevier Ltd.

However, the mechanisms leading to the coordinated collapse of phytoplankton blooms are poorly understood. We showed that the collapse of the annual bloom of Peridinium gatunense, an abundant dinoflagellate in Lake Kinneret, Israel, is initiated by CO2 limitation followed by oxidative stress that triggers a PCD-like cascade. We provide evidences that a protease excreted by senescing P. gatunense cells sensitizes younger cells to oxidative stress and may consequently trigger synchronized cell death of the population. Ageing of the P. gatunense cultures was characterized by a remarkable rise in DNA fragmentation and enhanced sensitivity to H2O2. Exposure of logarithmic phase (young) cultures to conditioning media from stationary phase (old) cells sensitized them to H2O2 and led to premature massive cell death. We detected the induction of specific extracellular protease activity, leupeptin-sensitive, in ageing cultures and in lake waters during the succession of the P. gatunense bloom. Partial purification of the conditioned media revealed that this protease activity is responsible for the higher susceptibility of young cells to oxidative stress. Inhibition of the protease activity lowered the sensitivity to oxidative stress, whereas application of papain to logarithmic phase P. gatunense cultures mimicked the effect of the spent media and enhanced cell death. We propose a novel mechanistic framework by which a population of unicellular phytoplankton orchestrates a coordinated response to stress, thereby determine the fate of its individuals.

Here we present the genetic analysis of Alexandrium tamarense (Lebour) Balech populations from 10 sites along the Japanese and Korean coasts. We used nine microsatellite loci, which varied widely in number of alleles and gene diversity across populations. The analysis revealed that Nei's genetic distance correlated significantly with geographic distance in pair-wise comparisons, and that there was genetic differentiation in about half of 45 pair-wise populations. These results clearly indicate genetic isolation among populations according to geographic distance and restricted gene flow via natural dispersal through tidal currents among the populations. On the other hand, high P-values in Fisher's combined test were detected in five pair-wise populations, suggesting similar genetic structure and a close genetic relationship between the populations. These findings suggest that the genetic structure of Japanese A. tamarense populations has been disturbed, possibly by human-assisted dispersal, which has resulted in gene flow between geographically separated populations.

J	Tang, YZ; Dobbs, FC				Tang, Ying Zhong; Dobbs, Fred C.			Green autofluorescence of dinoflagellate cysts can be used instead of primuline staining for cyst visualization and enumeration in sediments	JOURNAL OF PHYCOLOGY			English	Article						dinoflagellate cyst; green autofluorescence; Gymnodinium catenatum; primuline staining; Scrippsiella trochoidea	RESTING CYSTS; ALEXANDRIUM; GULF; DINOPHYCEAE; GERMINATION; ABUNDANCE	Primuline staining is widely used to visualize and enumerate dinoflagellate cysts in marine sediments. In staining cysts of Gymnodinium catenatum H. W. Graham, Scrippsiella trochoidea (F. Stein) A. R. Loebl., and cysts from estuarine sediments, we found their green fluorescence after primuline treatment to be seemingly no different from the green autofluorescence (GAF) inherent in vegetative cells and cysts of dinoflagellates fixed in formaldehyde. Although primuline subsequently proved to enhance green fluorescence of both species quantitatively, we nonetheless recommend taking advantage of dinoflagellates' GAF to detect and count their cysts in sediments. Doing so will reduce the time, chemical consumption, and possible loss of cells involved in the primuline-staining procedure.

J	Wang, ZH; Qi, YZ; Yang, YF				Wang, Zhao-Hui; Qi, Yu-Zao; Yang, Yu-Feng			Cyst formation:: an important mechanism for the termination of <i>Scrippsiella trochoidea</i> (Dinophyceae) bloom	JOURNAL OF PLANKTON RESEARCH			English	Article							NORTHERN BALTIC SEA; SOUTH CHINA SEA; RESTING CYSTS; DINOFLAGELLATE CYSTS; SPRING-BLOOM; POPULATION-DYNAMICS; SURFACE SEDIMENTS; ONAGAWA BAY; DAYA BAY; GERMINATION	A sediment trap study was conducted at Daya Bay, South China Sea, to investigate the relationships between encystment and population dynamics of Scrippsiella trochoidea from December 1999 to January 2001. A dense bloom of S. trochoidea occurred during the study period from August to September 2000, with the maximum cell number of 3.18 x 10(4) cells mL(-1). Two morphotypes of cysts, one with a thick calcareous wall (calcified cyst) and another without the obvious calcareous cover (non-calcified cyst), were observed during this investigation. The morphological and excystment characteristics of these two cyst types were studied as well. Mass encystments of S. trochoidea, with the maximum of 3.05 x 10(5) cysts m(-2) d(-1) for calcified cyst, and 1.54 x 10(7) cysts m(-2) d(-1) for non-calcified cyst, coincided with the maximum abundance of the vegetative cells. Encystment caused the transfer of a total of 2.24-4.49 x 10(8) cells m(-2) vegetative cells from the water column to the sea bottom during the bloom and resulted in a considerable loss of the bloom population. High assemblages of cysts of S. trochoidea were detected in the surface sediments as well. This rich 'seed bed' in the surface sediments caused by the high efficiency of encystment after blooms acting as a benthic reservoir for future vegetative population, together with the short dormant period (15-26 days) and high germination rate (50-90%), may explain the repeated occurrence of S. trochoidea blooms in Daya Bay.

Natural bacterioplankton assemblage composition during blooms of <i>Alexandrium</i> spp. (Dinophyceae) in NW Mediterranean coastal waters	AQUATIC MICROBIAL ECOLOGY			English	Article						FISH; dinoflagellates; HAB; Alexandrium; Roseobacter; Alteromonas	PARALYTIC SHELLFISH TOXINS; PELAGIC MARINE-BACTERIA; OLIGONUCLEOTIDE PROBES; PHYLOGENETIC DIVERSITY; COMMUNITY COMPOSITION; DINOFLAGELLATE BLOOM; FUNCTIONAL DIVERSITY; POPULATION-DYNAMICS; ALGICIDAL BACTERIA; CYST FORMATION	We characterised the spatial and temporal variation in the bacterioplankton assemblage composition during bloom events of different Alexandrium species (Dinophyceae) in the littoral of the NW Mediterranean Sea by means of catalysed reporter deposition fluorescence in situ hybridisation with oligonucleotide probes (CARD-FISH). We studied several Alexandrium blooms through their seasonal development (at La Fosca beach) or in their spatial variability (in Arenys Harbour and Olbia Bay), and we complemented these observations by describing the composition of the bacterial assemblage associated with cultures of Alexandrium species isolated from the same sites. Our studies on natural bacterioplankton assemblages identified the Bacteroidetes lineage and the Alphaproteobacteria as the dominating components during the studied blooms of Alexandrium. Alphaproteobacteria dominated in the La Fosca and Olbia blooms, while bacteria belonging to the Bacteroidetes were abundant in the development phase of the La Fosca beach bloom and in the winter Arenys bloom. Gammaproteobacteria contributed in low proportions without significant changes through the different bloom phases at La Fosca beach and in Olbia Bay, but were more abundant in Arenys Harbour. While the absolute bacterial abundances in the spatial study of Olbia Bay covaried with the Alexandrium densities, there were no spatial changes in the bacterioplankton assemblage composition. Alteromonas-like organisms were never an important fraction of the assemblage, but Roseobacter dominated Alphaproteobacteria in Arenys Harbour. Furthermore, the bacterioplankton assemblages associated with Alexandrium spp. cultures were very different from the natural bacterial assemblages during blooms of the same species. We conclude that the presence of a given harmful algal bloom species during a bloom will not always necessarily be accompanied by the same bacterial assemblage structure, and studies done with dinoflagellate cultures may only reflect the bacteria capable of growing under laboratory conditions, with little resemblance to what occurs under natural conditions.

C. gigas produced faeces and pseudofaeces containing intact and viable temporary pellicular cysts of these two Paralytic toxin producing species. When incubated in favourable conditions, these pellicular cysts were able to germinate at high rates (between 74 and 94%) and the resulting vegetative cells divided with growth rates close to the non-ingested cells (control). The toxin profile of the vegetative cells originated from the germinated temporary cysts was analyzed by liquid chromatography/ fluorescence detection. Total toxin content of newly germinated cells was lower than that of cultured cells. Besides, cell contents of C2, B1, B2 and dcGTX3 toxins featured some changes. Our results suggest that the increased spreading of toxic dinoflagellates through the transfer of shellfish from contaminated towards pristine coastal areas cannot be ruled out. We also suggest that pellicular cysts and newly germinated cells could represent a potential way for the transfer of paralytic toxins toward the higher trophic levels.

Modulation of ecdysal cyst and toxin dynamics of two <i>Alexandrium</i> (Dinophyceae) species under small-scale turbulence	BIOGEOSCIENCES			English	Article							POPULATION-GROWTH; NET GROWTH; DINOFLAGELLATE; PLANKTON; PHYTOPLANKTON; ENVIRONMENTS; CATENELLA; COMMUNITY; MODELS; RATES	Some dinoflagellate species have shown different physiological responses to certain turbulent conditions. Here we investigate how two levels of turbulent kinetic energy dissipation rates (epsilon = 0.4 and 27 cm(2) s(-3)) affect the PSP toxins and ecdysal cyst dynamics of two bloom forming species, Alexandrium minutum and A. catenella. The most striking responses were observed at the high epsilon generated by an orbital shaker. In the cultures of the two species shaken for more than 4 days, the cellular GTX(1+4) toxin contents were significantly lower than in the still control cultures. In A. minutum this trend was also observed in the C(1+2) toxin content. For the two species, inhibition of ecdysal cyst production occurred during the period of exposure of the cultures to stirring (4 or more days) at any time during their growth curve. Recovery of cyst abundances was always observed when turbulence stopped. When shaking persisted for more than 4 days, the net growth rate significantly decreased in A. minutum (from 0.25 +/- 0.01 day(-1) to 0.19 +/- 0.02 day(-1)) and the final cell numbers were lower (ca. 55.4%) than in the still control cultures. In A. catenella, the net growth rate was not markedly modified by turbulence although under long exposure to shaking, the cultures entered earlier in the stationary phase and the final cell numbers were significantly lower (ca. 23%) than in the control flasks. The described responses were not observed in the experiments performed at the low turbulence intensities with an orbital grid system, where the population development was favoured. In those conditions, cells appeared to escape from the zone of the influence of the grids and concentrated in calmer thin layers either at the top or at the bottom of the containers. This ecophysiological study provides new evidences about the sensitivity to high levels of small-scale turbulence by two life cycle related processes, toxin production and encystment, in dinoflagellates. This can contribute to the understanding of the dynamics of those organisms in nature.

Eighty-eight diatom taxa representing 48 genera, many of which have been rarely observed, and 14 dinoflagellate cyst genera with 20 taxa were identified in Rookery Bay. All taxa are briefly annotated and documented by light micrographs. The most common diatom taxa in the surface sediment sample are Amphicocconeis disculoides, Chaetoceros resting spores, Cyclotella litoralis, Cyinatosira belgica, Neodelphineis pelagica, Paralia sulcata, and Pleurosigina rhombeum. The most abundant dinoflagellate cyst taxa in the surface sample include Brigantedinium spp., Lingulodinium machaerophorum, Polyspheridium zoharyi, Spiniferites bentorii, and Spiniferites ramosus.

An alternative life-cycle with the production of vegetative calcareous cells as the dominant life-cycle stage was reported for the oceanic calcareous dinoflagellate Thoracosphaera heimii, and earlier observations suggested that other oceanic calcareous dinoflagellates might have similar life-cycles. In order to test this hypothesis, we investigated the life-cycle of three oceanic calcareous dinoflagellates, Thoracosphaera heimii, Leonella granifera and Calciodinellum levantinum in culture and determined relative ploidy levels with confocal laser scanning microscopy. Whereas C. levantinum forms calcareous resting cysts within the diploid sexual life-cycle phase, T. heimii and L. granifera form vegetative calcareous cells within the haploid asexual phase. By comparison with recently published molecular phylogenies, we conclude that C. levantinum is part of a group of mainly neritic species, from which oceanic species evolved repeatedly. The life-cycle of C. levantinum is basically identical to that of its neritic relatives. A reduced dormancy period is interpreted as an adaptation to the oceanic environment. By contrast, T. heimii and L. granifera are part of a clade of dinoflagellates in which the haploid vegetative life- cycle phase has diversified and enabled their members to access new habitats. While the primary calcification during the diploid phase was lost in this group, calcification was regained secondarily in the haploid vegetative life- cycle phase in T. heimii and L. granifera. Therefore the vegetative calcareous cells are not homologous with the calcareous resting cysts formed in other calcareous dinoflagellates, which may also be expressed in different biomineralization modes.

However, little is known about the life cycle of the species, except for the planktonic vegetative stage; therefore, the aim of this paper was to elucidate the life cycle of C polykrikoides. Its life cycle has two morphologically different stages: an armored and an unarmored vegetative stage. Armored vegetative cells were found in seawater samples collected in late-November and developed into four-cell chained, unarmored vegetative cells under laboratory culture. In samples collected in late-May, both the armored and unarmored types (vegetative swimming stage) occurred; the former easily developed into an unarmored vegetative cell type, suggesting that the armoured-unarmored transition occurs as early as May. A presumptive resting cyst, round but folded at one side, was produced from armored type cells in laboratory conditions. It was also collected from natural bottom sediments, which suggests it is the dormant resting cyst of C. polykrikoides. (c) 2006 Elsevier B.V. All rights reserved.

In mid-January local residents reported bioluminescence in the Sea. Starting in February, large rafts of long-lasting foam, also bioluminescent, were observed as well. Microscopy investigations on water and sediment samples collected in March showed the marine dinoflagellate, Alexandrium margalefii, and the prymnesiophyte, Prymnesium sp., both previously unreported in the Salton Sea, to be abundant. Bioluminescence and foam production continued through March. Other dinoflagellate species, recorded during earlier studies, were rare or not detected during these blooms. Despite the fact that many Alexandrium species are known paralytic shellfish poison (PSP) producers, preliminary saxitoxin tests on this population of A. margalefii were negative. Previous reports on A. margalefii do not mention bioluminescence. It appears that the foam was caused by the Prymnesium sp. bloom, probably via protein-rich exudates and lysis of other algal cells, and its glow was due to entrained A. margalefii. This is the first report of A. margalefii in U.S. waters and the first report of it in a lake.

J	Lucas-Clark, J				Lucas-Clark, Joyce			<i>Litosphaeridium</i> too:: Two new dinoflagellate cyst species from the Cretaceous of California	PALYNOLOGY			English	Article						dinoflagellate cysts; taxonomy; Cretaceous; California	FRANCISCAN	The 'Middle' Cretaceous of the Northern California Coast Ranges has yielded unusually well-preserved specimens of Litosphaeridium, some of which (Litosphaeridium arundum, Litosphaeridium bacar, Litosphaeridium conispinum, and Litosphaeridium siphoniphorum subsp. glabrum) have been analyzed in detail previously. Two other species, which were discovered later, are Litosphaeridium adnatum sp. nov. and Litosphaeridium gaponoffiae sp. nov. Litospheridium adnatum sp. nov. is most similar to Litosphaeridium siphoniphorum, but has an adnate operculum, sulcal processes, a more elongate central body, and less of the central body is covered by processes. The other, Litosphaeridium gaponoffiae sp. nov., is most similar to Litosphaeridium arundum and Litospheridium fucosum, but has goblet-shaped processes, a free operculum, a more spherical central body, and its cingular processes are not reduced as they are in Litospheridium arundum. The two species are from the late Albian based on the associated dinoflagellate cysts.

Protists in the marine ice of the Amery Ice Shelf, East Antarctica	POLAR BIOLOGY			English	Article							SOUTHERN-OCEAN SEDIMENTS; WATER-COLUMN ASSEMBLAGES; MAJOR DIATOM TAXA; SEA-ICE; SURFACE SEDIMENTS; MASS-BALANCE; WEDDELL SEA; BENEATH; PHYTOPLANKTON; BIOGEOGRAPHY	Samples of marine ice were collected from the Amery Ice Shelf, a large embayed ice shelf in East Antarctica, during the Austral summer of 2001-2002. The samples came from a site -90 km from the iceberg calving front of the shelf, where the ice is 479 m thick and the lower 203 m is composed of accreted marine ice. Protists identified within the marine ice layer of the Amery Ice Shelf include diatoms, chrysophytes, silicoflagellates and dinoflagellates. The numerical dominance of sea ice indicator diatoms such as Fragilariopsis curta, Fragilariopsis cylindrus, Fragilariopsis rhombica and Chaetoceros resting spores, and the presence of cold open water diatoms such as Fragilariopsis kerguelensis and species of Thalassiosira suggest the protist composition of the Amery marine ice is attributable to seeding from melting pack and/or fast ice protist communities in the highly productive waters of Prydz Bay to the north.

J	Persson, A; Smith, BC; Wikfors, GH; Quilliam, M				Persson, Agneta; Smith, Barry C.; Wikfors, Gary H.; Quilliam, Michael			Grazing on toxic <i>Alexandrium fundyense</i> resting cysts and vegetative cells by the eastern oyster (<i>Crassostrea virginica</i>)	HARMFUL ALGAE			English	Article						Alexandrium fundyense; Crassostrea virginica; cyst; dinoflagellate; grazing; oyster; PSP; toxic	DINOFLAGELLATE GONYAULAX-TAMARENSIS	In laboratory experiments, oysters (Crassostrea virginica) were fed Alexandrium fundyense (strain C13501) vegetative cells or resting cysts (from strains CB501 and GMT25) produced from laboratory cultures. The toxicity per cyst was 1.7 pg STXequiv/cyst and for vegetative cells 3.9 pg STXequiv/cell. The toxic, resting cysts and vegetative cells were removed from suspension in the experimental containers within about 4 It. Oysters fed toxic vegetative cells digested 72% of cells ingested, and 28% survived gut passage by forming temporary cysts. Toxin levels of oysters fed vegetative cells averaged 27 mu g STXequiv/100 g meat. Resting cysts added to the experimental containers adhered to the walls so that only 40% of the cysts added were available to the oysters during the experiment. Of the cysts that were ingested, approximately 59% were digested, and oysters accumulated toxins (an average of 1.2 mu g STXequiv/100 g meat), showing that consumption of resting cysts can cause toxicity in oysters. Direct consumption of resting cysts, thus, may explain shellfish toxicity in areas without known blooms, but with toxic resting cysts in the sediment. These results suggest a possible role of toxic cysts in mediating time-lags between surface blooms and appearance of toxicity in benthic grazers, and the possible role of benthic grazers in controlling seed populations, except in anoxic areas, which can serve as cyst "refuges" from grazing mortality.

Other epiphytic dinoflagellates of the genera Prorocentrum and Amphidinium and diatoms were accompanying species in this epiphytic community. Morphometric features, plate formula and thecal ornamentation were used for species identification. O. ovata cells were smaller in dorsoventral (DV) diameter and width (W) (26.18-61.88 mu m and 13.09-47.60 mu m, respectively) in comparison with O. cf. siamensis (35.70-65.45 mu m and 23.80-49.98 mu m, respectively). In contrast, the anterioposterior (AP) diameter of O. cf. siamensis was smaller (14.28-26.18 mu m) resulting in DV/AP approximate to 3, whereas the above ratio for O. ovata was less than 2 (AP ranging between 14.28-35.70 mu m). Moreover, the theca of O. ovata cells was ornamented with scattered pores, which fluctuated in a wider range (0.07-0.32 mu m) than those of O. cf. siamensis (0.23-0.29 mu m). Coolia monotis cells were almost round with average DV diameter 26.88 mu m, AP 25.66 mu m and width 26.76 mu m. Small and large cells were recorded in both field and culture populations of Ostreopsis spp. and C. monotis, while hyaline cysts were observed for O. ovata. The presence of O. ovata and O. cf. siamensis exhibited a clear seasonal pattern dominating (maximum abundance up to 4.05 x 10(5) cells gr(-1) fwm) the period from midsummer to late autumn in years 2003 and 2004, while C. monotis was found also in winter and spring months.

Temperature as a factor regulating growth and toxin content in the dinofiagellate <i>Alexandrium catenella</i>	HARMFUL ALGAE			English	Article						Alexandrium catenella; dinoflagellate; temperature; growth rates; toxin content; PSP; HABs	CYST FORMATION; DINOFLAGELLATE; DINOPHYCEAE; POPULATION; TAMARENSE	Controlled laboratory culture of Alexandrium catenella was used to determine the effects of a range of temperatures between 10 and 16 degrees C on the growth and saxitoxin content of this dinoflagellate, using strain ACC02 isolated from seawater at Aysen, XI Region, Southern Chile. Cell cultures were made using L1 culture medium at 30 parts per thousand salinity, and a photon flux density of 59.53 mu mol m(2) s(-1). The results showed that the duration of the exponential growth phase was determined by the experimental temperature, with maximum cell concentrations obtained at 12 degrees C; significantly lower cell concentrations and growth rates were obtained at 16 degrees C. Cell dry weight and chlorophyll a values followed cell growth trends. The toxicity of A. catenella was variable at all the experimental temperatures, with a tendency towards having an inverse relation to temperature, with the highest values occurring at 10 degrees C and the lowest at 16 degrees C. The optimal range of temperature for the growth of the Chilean strain of A. catenella differed from rates reported for this species isolated at other latitudes, and was correlated with natural temperature conditions predominant in the environment from which it was isolated. The inverse relation of toxicity with temperature in the laboratory was broadly reflected in observations on the toxicity of this dinoflagellate in the field, and coincided with results from the literature.

Here, we used TEM to investigate the mechanism of cellular fusion during the sexual life cycle in Dinophysis fortii Pavillard. We observed that fusion always occurred between a normal-sized cell and a small cell following attachment of their ventral margins. After cell attachment, the small cell moved toward the epitheca of the normal-sized cell, and the cingular and sulcal lists of the small cell shrunk or were almost lost. The epitheca of the normal-sized cell then opened between the cingulum plates and the upper cingular list, after which the small cell was gradually engulfed. This is the first ultrastructural observation in a dinoflagellate of a larger cell opening its epitheca to engulf the smaller gamete. In another case, the normal-sized cell did not open the epitheca, the cell wall of the attached small cell underwent extensive extracellular digestion, and the cytoplasm appeared to flow into the normal-sized cell via the periflagellar area. Inflow of the nucleus was not observed in this case, suggesting that it represented a failure of sexual fusion. In both cases, membranous separations between the cytoplasm of the two cells were not observed. At the beginning of the fusion process, the nucleus of the small cell was substantially deformed. The plano-zygote, formed upon completion of sexual fusion, sometimes had two longitudinal flagella, but was identical to a normal vegetative cell in its cellular shape, as already mentioned by previous authors.

The benthic resting cyst: A key actor in harmful dinoflagellate blooms - A review	VIE ET MILIEU-LIFE AND ENVIRONMENT			English	Review						seeding; bioturbation; maturation; distribution mode; density; sediment; germination; recruitment; suspended cyst; geographic strain	ALEXANDRIUM-TAMARENSE DINOPHYCEAE; GONYAULAX-TAMARENSIS; SURFACE SEDIMENTS; ALGAL BLOOMS; TOXIC DINOFLAGELLATE; ENVIRONMENTAL-FACTORS; SCRIPPSIELLA-HANGOEI; MARINE-SEDIMENTS; LIFE-HISTORY; INLAND SEA	Resting cysts (RC) constitute a coupling between benthic and pelagic stages and influence the bloom development in a number of bloom forming dinoflagellate species. Encystment capability coupled with high vegetative cell density (> one million cells 1(-1)) contribute to the formation of an accumulation zone: '' the cyst bank '', which is directly linked to the success of bloom initiation and its recurrence. The survival time of benthic RCs (few weeks to their viability which could be negatively affected by predation, and their mandaseveral years), mandatory dormancy period (few days to several months) are variable and influence the seeding potential of the population significantly. Excystment rate, mainly controlled by temperature and oxygen level, and the germling cells' viability determine the inoculum size. Many biological processes in RCs have been shown to be controlled by endogenous and environmental factors, and vary between species and within the same species as a function of geographic strains.

We have re-examined the cyst-motile relationship of P. thulesense by cyst incubation and thecal plate analysis together with a molecular phylogenetic study based on small subunit (SSU) rDNA sequences. Five isolates of P. thulesense, including motile cells and cysts, and three Protoperidinium and three diplopsalid species were examined by using the single cell PCR method. The thecal plate arrangement of the motile cells isolated from field samples and those germinated from cysts were identical. The plate formula was: Po, X, 3 ', 3a, 7 '', 3c+t, 4s, 5 ''', 2 ''''. The cysts of P. thulesense were round and brown with a theropylic archeopyle, and rather similar to the diplopsalid species, Diplopsalis lenticula, D. lebourae, Gotoius abei and others. SSU rDNA sequence analysis reveals P. thulesense is closely related to the subgenus Protoperidinium, especially species of the section Conica, and distant from the diplopsalid species. The phylogenetic and taxonomic significances of Protoperidinium and diplopsalid round brown cysts with a theropylic archeopyle are discussed.

The nuclear development of the cells during the sexual cycle and the effect of different external nitrate and phosphate levels were studied. Nuclear fusion of gametes occurred 6-12 h after the complete cytoplasmic fusion. The U-shaped nuclei fused through the end of one nucleus and the mid-area of the other. The mobile and biflagellated zygote had a large, U-shaped nucleus and may follow three different fates: direct division, short-term encystment (ecdysal), and long-term encystment (resting). Ecdysal cysts may divide in > 24-96 h into two, four, six, or eight cells before germinating. Meiosis presumably occurred in three locations: in the planozygote, within the ecdysal cyst, and in the planomeiocyte (germling) liberated either from ecdysal or resting cysts. The effects of nutrients on these routes were studied in individually isolated sexual stages. (1) Direct divisions occurred mainly under replete conditions (L1), whereas no direct planozygote divisions were recorded in media with no phosphate added (L-P). (2) Short-term encystment was larger in media lacking phosphate (L-P and L/30) than in medium with no nitrate added (L-N) or under replete conditions (L1). (3) Long-term encystment was only observed in medium with no nitrate added (L-N). The long-lived resting cyst, not previously described for this species, had a clear double wall, an irregular shape, a flat morphology, and a middle orange spot. No cysts germinated in 1-2 months, whereas 86% of the cysts germinated 2-3 months after being formed. A flow cytometry analysis showed that sexual induction and zygote formation were very fast and highly common processes, zygotes being nearly half of the population at days 3 and 5 after the induction of sexuality in the cultures.

Rapid flow cytometric method for the assessment of toxic dinoflagellate cyst viability	MARINE ENVIRONMENTAL RESEARCH			English	Article						ballast water; dinoflagellate cyst; alexandrium catenella; flow cytometry; viability	SHIPS BALLAST WATER; SYTOX GREEN; MARINE; TRANSPORT; BIOASSAY; SPORES	The inadvertent transfer and dispersal of non-indigenous marine species via shipping ballast water is of increasing environmental concern. Despite a major global effort to develop new ballast water treatment technologies, their acceptance has been hampered by the lack of suitable indicator species for assessing treatment effectiveness. Resistant dinoflagellate cysts are one proposed test organism, however their use has been limited due to difficulties in assessing their viability after treatment. The paper describes the development of a rapid method to determine the viability of cysts of the dinoflagellate Alexandrium catenella using staining with SYTOX (R) Green and flow-cytometric analysis. The viability of A. catenella cysts was inversely proportional to their ability to take up the stain. There was excellent agreement between cysts measured as viable/non-viable using flow cytometry and cyst viability determined in standard long-term germination tests. Advantages of the flow-cytometric method include high test precision and rapid testing times of < 2 days, compared to > 4 weeks using existing germination methods.

J	Thibodeau, B; de Vernal, A; Mucci, A				Thibodeau, Benoit; de Vernal, Anne; Mucci, Alfonso			Recent eutrophication and consequent hypoxia in the bottom waters of the Lower St. Lawrence Estuary: Micropaleontological and geochemical evidence	MARINE GEOLOGY			English	Article						Lower St. Lawrence Estuary; eutrophication; hypoxia; dinoflagellate cysts; benthic foraminifera; geochemistry	BENTHIC FORAMINIFERAL ASSEMBLAGE; SURFACE OCEAN PRODUCTIVITY; DINOFLAGELLATE CYSTS; CHESAPEAKE BAY; CONTINENTAL-SHELF; MODERN SEDIMENTS; ORGANIC-MATTER; ATLANTIC; MARINE; OXYGEN	Micropaleontological and gechemical analyses were carried out on two sediment box cores (AH00-2220 and CR02-23) recovered in the Lower St. Lawrence Estuary (LSLE) in order to document recent temporal variations of primary productivity and carbon fluxes to the bottom waters. These reveal a ten-fold increase in the accumulation rate of dinoflagellate cysts and benthic foraminifera in the sediment over the last four decades which can be interpreted as a recent increase in pelagic and benthic production. Furthermore, the appearance of the benthic foraminiferal species Brizalina subaenariensis and Bulimina exilis, which are tolerant of low oxygen concentrations and high organic,fluxes, in the upper 20 cm of the cores, may reflect significant changes in bottom water conditions over the last 40 yrs. Variations in the microfossil abundances in core AH00-2220 are strongly correlated with an increase in organic carbon (OC) content (from 1.1 to 1.6%) and to a shift in the isotopic signature of the latter (delta C-13(ORG) from -24.8 to -24.0 parts per thousand). Similarly, a concomitant decrease in the C-ORG:N ratio (from 15 to 12), an increase in organic carbon content (from 1.3 to 1.9%) and an increase in delta C-13(ORG) (from -24.5 to -23.5 parts per thousand) were observed in core CR02-23, all of which suggest an enhanced accumulation of marine over terrestrial OC in the LSLE. Our results imply that a significant increase in marine productivity in the LSLE occurred since the 1960's. (c) 2006 Elsevier B.V. All rights reserved.

The taxonomy and growth of a <i>Crypthecodinium</i> species (Dinophyceae) isolated from a brackish-water fish aquarium	AFRICAN JOURNAL OF MARINE SCIENCE			English	Article; Proceedings Paper	11th International Conference on Harmful Algae	NOV 15-19, 2004	Cape Town, SOUTH AFRICA			Crypthecodinium; dinoflagellate; phylogeny; small sub-unit rDNA; taxonomy; theca	ALGA PORPHYRIDIUM SP; CELL-CYCLE; COHNII; COMPLEX; MEMBERS	An unidentified heterotrophic dinoflagellate found growing in abundance in a brackish-water fish aquarium was isolated and serially cultivated using a fish cell line as the food source. Prominent characteristics of this dinoflagellate included a cingulum that did not fully encircle the motile cell, cell division in non-motile cysts, and a theca composed of thin but structured plates. Morphological analysis of flagellate cells by scanning electron microscopy revealed a Kofoid thecal plate tabulation of 4', 4a, 4", 'X', 5 or 6c, ?s, 5"', 1p, 1'''', most consistent with the original description of Crypthecodinium setense Biecheler. This Crypthecodinium species exhibited a high maximum division rate (3.2 divisions day(-1)) and cell yield (> 10(6) cells ml(-1)) when fed cultured fish cells. Small sub-unit rDNA phylogenetic analyses supported relatedness with a previously studied Crypthecodinium-like dinoflagellate, but a significant difference in aligned gene sequences was found. This study provides the first clear demonstration of the plate tabulation of a Crypthecodinium species since the original description over 60 years ago, allowing the original morphological conception of Crypthecodinium to be linked with molecular phylogenetic information.

Historical cyst record as evidence for the recent introduction of the dinoflagellate <i>Gymnodinium catenatum</i> in the north-eastern Atlantic	AFRICAN JOURNAL OF MARINE SCIENCE			English	Article; Proceedings Paper	11th International Conference on Harmful Algae	NOV 15-19, 2004	Cape Town, SOUTH AFRICA			ballast water introduction; cysts; eutrophication; Gymnodinium catenatum		The geographical origin of the warm-temperate paralytic shellfish poison producer Gymnodinium catenatum Graham is still under debate. It was first reported in the north-eastern Atlantic in 1976, from the Galician rias (North-West Iberia). Since then, and until 1995, recurrent blooms were recorded, with north-south progression of the affected areas, eventually affecting the whole West and South Atlantic coasts of Iberia and the Moroccan coast. This study presents results obtained from cyst analyses of a (210)Pb-dated box core and a (14)C-dated piston core, collected off Iberia, covering the last 2 000 years. They indicate that G catenatum is not endemic to the area but has been introduced around the beginning of the last century, coinciding with another major environmental change, possibly related to cultural eutrophication.

Cysts of <i>Alexandrium catenella</i> on the west coast of South Africa:: distribution and characteristics of germination	AFRICAN JOURNAL OF MARINE SCIENCE			English	Article; Proceedings Paper	11th International Conference on Harmful Algae	NOV 15-19, 2004	Cape Town, SOUTH AFRICA			Alexandrium catenella; cysts; southern Benguela	GONYAULAX-TAMARENSIS; RESTING CYSTS; DINOPHYCEAE; SCRIPPSIELLA; TEMPERATURE; DARKNESS	Cysts of the toxic dinoflagellate Alexandrium catenella (Whedon and Kofoid) Balech were found in the sediments of the southern Namaqua shelf, on the west coast of South Africa, with a maximum recorded abundance of 238 cysts ml(-1) wet sediment. Experimental results indicate a short dormancy period of 15-18 days, suggesting that the cyst population does not necessarily serve as an overwintering strategy, but may rather permit rapid cycling between benthic and planktonic stages. Cysts were isolated monthly from sediments and incubated in the laboratory. Cyst germination ranged between 20% and 88% and did not show a clear seasonal pattern. The rate of germination was examined as a function of temperature and light. Cysts germinated within the temperature range 4 degrees-22 degrees C, but germination was highest at 10 degrees C under both light and dark conditions. Although cysts germinated in the dark, germination in the light was higher and required a shorter period of incubation.

Cysts of potentially harmful dinoflagellates, with emphasis on the genus <i>Alexandrium</i>, in Sepetiba Bay (Brazil) during a port survey of GloBallast	AFRICAN JOURNAL OF MARINE SCIENCE			English	Article; Proceedings Paper	11th International Conference on Harmful Algae	NOV 15-19, 2004	Cape Town, SOUTH AFRICA			Alexandrium; ballast water; dinoflagellate cysts; Sepetiba Bay	TRANSPORT	Sepetiba Bay in south-eastern Brazil has been selected as a pilot demonstration site within the Global Ballast Water Management Programme (GloBallast; IMO/PNUD/ GEF). As part of the port baseline survey, a series of 43 sediment cores was taken in triplicate in the bay in November 2001, by SCUBA divers, using PVC tubes. The top 60mm of each core was processed for dinoflagellate cyst analysis. Cysts of the potentially toxic Alexandrium cf. minutum were identified in 41% of the samples, but the highest density (22 cysts cm(-3)) was found in the port area, at the Iron Ore Terminal. Other Alexandrium-type cysts were observed in 37% of the samples and their highest density (26 cysts cm(-3)) was also associated with the port area. These results indicate that the northern area of the bay is unsuitable for the intake by ships of ballast water. This investigation highlights the importance of cyst surveys to the management of ballasting and deballasting in port areas.

Detection of <i>Pfiesteria</i> spp. by PCR in surface sediments collected from Chesapeake Bay tributaries (Maryland)	HARMFUL ALGAE			English	Article						PCR; Pfiesteria; sediment; Chesapeake Bay	PISCICIDA; DNA; AMPLIFICATION; POLYMERASE; DISCOVERY; IMPACTS; ASSAYS; GENE	In 1997 blooms of Pfiesteria piscicida occurred in association with fish kills and human health problems in tributaries of the Chesapeake Bay (Maryland) and the scientific and media response resulted in large economic losses in seafood sales and tourism. These events prompted the Maryland Department of Natural Resources (MDNR) to begin monitoring for Pfiesteria spp. in water column samples. Real-time PCR assays targeted to the 18S rRNA gene were developed by our laboratories and utilized in conjunction with traditional microscopy and fish kill bioassays for detection of these organisms in estuarine water samples. This monitoring strategy aided in determining temporal and spatial distribution of motile forms of Pfiesteria spp. (i.e. zoospores), but did not assess resting stages of the dinoflagellates' life cycle. To address this area, a 3-year study was designed using real-time PCR assays for analysis of surface sediment samples collected from several Chesapeake Bay tributaries. These samples were tested with the real-time PCR assays previously developed by our laboratories. The data reported herein suggest a strong positive association between presence of Pfiesteria spp. in the sediment and water column, based on long-term water column monitoring data. P. piscicida is detected more commonly in Maryland's estuarine waters than Pfiesteria shumwayae and sediment 'cyst beds' may exist for these organisms. (c) 2006 Published by Elsevier B.V.

In this study, molecular methods were used to investigate the distributions of benthic stages (cysts) of P piscicida in sediment cores from the Delaware Inland Bays. Cores from 35 sites were partitioned into nephloid and anoxic layers and analyzed for P piscicida by nested amplification of the 18S rDNA gene using P. piscicida-specific primers. The presence of inhibitory substances in the PCR reaction was evaluated by inclusion of an exogenous control DNA in the extraction buffer, thus eliminating samples that may yield false-negative results. Our results indicate a patchy distribution of R piscicida in sediments of the Delaware Inland Bays, with distinct differences between each of the three bays. Overall, P. piscicida was found more frequently in sediments from Rehoboth Bay compared to Indian River and Little Assawoman Bays. These differences suggest (i) that populations of P. piscicida may be more widely distributed in Rehoboth Bay, (ii) that populations of P. piscicida may have been introduced to Rehoboth Bay at an earlier time, (iii) that past blooms of P. piscicida in Rehoboth Bay estuaries may have seeded the sediments with higher numbers of cysts, and/or (iv) that Rehoboth Bay sediments may be more resistant to clearing due to storm turbulence.

In separate trials with larvae of A. irradians, C. virginica, and M. mercenaria, an aggressive predatory response of three strains of algal- and fish-fed P. shumwayae was observed (exception, algal-fed strain 1024C). Larval mortality resulted primarily from damage inflicted by physical attack of the flagellated cells, and secondarily from Pfiesteria toxin, as demonstrated in larval C virginica exposed to P shumwayae with versus without direct physical contact. Survival of adult shellfish and grazing activity depended upon the species and the cell density, strain, and nutritional history of P. shumwayae. No mortality of the four shellfish species was noted after 24 h of exposure to algal- or fish-fed P. shumwayae (strains 1024C, 1048C, and CCMP2089) in separate trials at <= 5 x 10(3) cells ml(-1), whereas higher densities of fish-fed, but not algal-fed, populations (> 7-8 x 10(3) cells ml(-1)) induced low (<= 15%) but significant mortality. Adults of all four shellfish species sustained > 90% mortality when exposed to fish-fed strain 270A1 (8 x 10(3) cells ml(-1)). In contrast, adult M. mercenaria and P viridis exposed to a similar density of fish-fed strain 2172C sustained < 15% mortality, and there was no mortality of A. irradians and C. virginica exposed to that strain. In mouse bioassays with tissue homogenates (adductor muscle, mantle, and whole animals) of A. irradians and M. mercenaria that had been exposed to R shumwayae (three strains, separate trials), mice experienced several minutes of disorientation followed by recovery. Mice injected with tissue extracts from control animals fed cryptomonads showed no response. Grazing rates of adult shellfish on P. shumwayae (mean cell length +/- 1 standard error [S.E.], 9 +/- 1 mu m) generally were significantly lower when fed fish-fed (toxic) populations than when fed populations that previously had been maintained on algal prey, and grazing rates were highest with the nontoxic cryptomonad, Storeatula major (cell length 7 +/- 1 mu m). Abundant cysts of P. shumwayae were found in fecal strands of all shellfish species tested, and <= 45% of the feces produced viable flagellated cells when placed into favorable culture conditions. These findings were supported by a field study wherein fecal strands collected from field-collected adult shellfish (C virginica, M. mercenaria, and ribbed mussels, Geukensia demissa) were confirmed to contain cysts of P. shumwayae, and these cysts produced fish-killing flagellated populations in standardized fish bioassays. Thus, predatory feeding by flagellated cells of R shumwayae can adversely affect survival of larval bivalve molluscs, and grazing can be depressed when adult shellfish are fed P. shumwayae. The data suggest that R shumwayae could affect recruitment of larval shellfish in estuaries and aquaculture facilities; shellfish can be adversely affected via reduced filtration rates; and adult shellfish may be vectors of toxic P shumwayae when shellfish are transported from one geographic location to another.

Resting cysts of the toxigenic dinofiagellate genus <i>Alexandrium</i> in recent sediments from the Western Mediterranean coast, including the first description of cysts of <i>A-kutnerae</i> and <i>A-peruvianum</i>	EUROPEAN JOURNAL OF PHYCOLOGY			English	Article						Alexandrium; dinoflagellate cysts; Mediterranean sea	GONYAULAX-EXCAVATA; DINOPHYCEAE; MINUTUM; CATENELLA; TAMARENSIS; MORPHOLOGY; SEQUENCE; STRAIN; BLOOMS; WATERS	Cyst studies carried out in 2002-2003 on Mediterranean Sea sediment from seven different sites along the Catalan and Balearic coasts (Western Mediterranean) revealed a higher diversity of Alexandrium species in the region than was previously known. The cysts of eight species of the toxigenic, marine dinoflagellate genus Alexandrium are described, and some, such as A. kutnerae, A. margalefi, A. peruvianum and A. pseudogoniaulax, are reported from the area for the first time. This is also the first record of resting cysts of A. taylori in Mediterranean sediment, and the first description known to date of resting cysts for A. kutnerae and A. peruvianum. All the cysts were characterized by a smooth wall except for the paratabulated cyst of A. pseudogoniaulax, and most of them had a prominent yellow/orange accumulation body. Nevertheless, we have also detected an unparatabulated cyst of A. pseudogoniaulax, both from the sediment and in cultures. The cyst of A. kutnerae had a roughly cylindrical shape with rounded ends which makes it impossible to distinguish from resting cysts of A. tamarense and A. catenella, while the flattened round cysts of A. peruvianum were very similar to those of A. taylori. The cyst concentration data revealed A. catenella and A. minutum to be the most abundant cysts in the region, and they were detected in semi-enclosed waters, such as harbours. This highlights the importance of water exchange in the accumulation of cyst beds of these species, which has already been reported in the region by other authors for A. minutum. This paper contributes to the biogeographic distribution of some Alexandrium species, such as A. kutneare, A. margalefi, A. peruvianum and A. pseudogoniaulax, which have been reported only infrequently in a global context.

Strains were cultivated in GSe at 20 degrees C +/- 1 degrees C, 150 mu mol photons(.)m(-2.)s(-1) (12:12 light:dark cycle), and harvested during different growth phases. Growth rates were higher than in previous studies, varying between 0.70 and 0.82 day(-1). The highest cell yields were reached at 16 and 19 days, with maximum densities between 1090 and 3393 cells(.)mL(-1). Bahia de La Paz (BAPAZ) and Bahia de Mazatlan (BAMAZ) were the most toxic (101 pg STXeq.cell(-1)), whereas strains from Bahia Concepcion (BACO) were the least toxic (13 pg STXeq(.)cell(-1)). A strain isolated from cyst germination was one of the least toxic strains. No significant changes in toxin content with culture age were observed (0.2 and 0.6 pmol paralytic shellfish poisoning.cell(-1)). All strains contained neosaxitoxin (NEOSTX), decarbamoyl-saxitoxin (dcSTX), decarbamoyl-gonyautoxin-2,-3, (dcGTX2-3), N-sulfo-carbamoylsaxitoxin (B1), N-sulfo-carbamoylneosaxitoxin (B2), and N-sulfo-carbamoylgonyautoxin-2,-3 (C1-2). Bahia Concepcion strains had the highest content of C1; BAPAZ and BAMAZ strains had a higher percentage of NEOSTX. Differences in toxin composition with culture age were observed only in BAMAZ and BAPAZ strains. Cultures with a higher percentage of long chains had more NEOSTX, while those with a higher proportion of short chains had a lower content of NEOSTX. Gulf of California strains are characterized by a high proportion of NEOSTX, and seem to have evolved particular physiological responses to their environment that are reflected in the toxin profile, suggesting different populations.

Therefore, sediments from ships' ballast water tanks and four Finnish ports were sampled for dinoflagellate cysts and other phytoplankton. Untreated sediments were incubated at 10 degrees C and 20 degrees C in the local 6 psu salinity for 1, 4 and 7 days, and vegetative cells were examined with light and scanning electron microscope. Sediments were inhabited by various dinoflagellates, diatoms, chlorophytes, cyanophytes and small flagellates. Germinated dinoflagellates were found in 90% of ballast tanks and in all ports. Gymnodiniales spp. and Heterocapsa rotundata formed a major proportion of the proliferating dinoflagellate cells. One species, Peridinium quinquecorne, not previously reported from the Baltic Sea, was identified with SEM. The study emphasises that ships are potential transport vehicles for dinoflagellate cysts even in the low salinity Finnish waters, and small-sized dinoflagellates should be focused upon in ballast water studies.

The abundance of cysts of the bloom-forming dinoflagellate Peridinium gatunense in the sediments of Lake Kinneret and the effects of environmental conditions on encystment were studied in relation to bloom dynamics. Peak cyst formation coincided with the highest growth rate of the population, prior to bloom peak. 2. Peridinium cysts were counted in water and sediment corer samples from 2000 to 2003 and in archived sediment trap samples collected during 1993-94. The cyst data were examined in relation to ambient temperature and nutrient records, and revealed no direct correlation. 3. In laboratory encystment experiments with Peridinium cells collected from the lake, 0.2-3% of the vegetative cells encysted. Temperature, light and cell density had no significant effect on the percentage of encystment. 4. Cysts were always present in the lake sediments but their abundance in 'non Peridinium' years was much lower than after a massive bloom. Vegetative cells were always present in the water column after the collapse of the annual dinoflagellate bloom, potentially serving as the inoculum for the next bloom. We propose that the hardy cysts serve as an emergency 'gene bank' to initiate population build up following catastrophic die outs.

J	Spilling, K; Kremp, A; Tamelander, T				Spilling, Kristian; Kremp, Anke; Tamelander, Tobias			Vertical distribution and cyst production of <i>Peridiniella catenata</i> (Dinophyceae) during a spring bloom in the Baltic Sea	JOURNAL OF PLANKTON RESEARCH			English	Article							PLANKTONIC FOOD-WEB; SCRIPPSIELLA-HANGOEI; MIGRATION; PHYTOPLANKTON; MICROORGANISMS; SEDIMENTATION; GERMINATION; DYNAMICS; SIZE	Vertical distribution and cyst production of the chain-forming, spring dinoflagellate Peridiniella catenata were studied throughout the spring season of 2000 in the coastal Guy of Finland. Numbers of cells were monitored in the water column, and cyst sedimentation was recorded using multiple sediment traps moored at three discrete depths. At the onset of the spring bloom, most of the population was situated in the euphotic zone. When the bloom progressed, the population was more evenly dispersed throughout the water column. Coinciding with the decline of the spring bloom, after nitrogen depletion, a general reduction of cell size of P. catenata and a break-up of chains were observed. Resting cysts started to appear shortly after the peak of the bloom, in sedimentation traps moored at 30 and 40 in depth. Cysts were only retrieved from the uppermost sediment trap on three of the six sampling occasions, constituting only a small proportion of all cysts produced by P. catenata during spring. Our results suggest that cyst production of this vertically migrating organism takes place to a large extent in deep water layers and emphasizes the necessity of whole water column monitoring in studies aiming to understand in situ life-cycle transformations of vertically migrating dinoflagellates.

Most of the factors that have been investigated can be categorised as external (e.g. N/P-ratio, temperature), whereas internal factors on the generation of cyanobacteria blooms through their distinctive life cycle have not yet been sufficiently considered. To fill this gap and to investigate the dynamics of cyanobacteria life cycles, a numerical model has been developed. The model assumes that the life cycle is governed by the internal energy and nitrogen quotas of the cells, and discriminates four different stages: vegetative cells, vegetative cells with heterocysts, akinetes and recruiting cells (including germinates). The seasonal succession of life stages is simulated in a one-dimensional framework, and a typical bloom is successfully simulated with a set of plausible parameters. Observed interannual variations in the relative proportions of different life cycle stages can be explained as the direct result of life cycle dynamics. The results show that life cycle simulations are feasible and can be used to test hypotheses and to determine sensitivities regarding the role of cyanobacteria life cycles in marine and limnic environments. Our study indicates that prediction of cyanobacteria blooms has to be based on a detailed knowledge of all stages of the life cycle.

ENVIRONMENTAL MICROBIOLOGY			English	Article							EGGS; APICOMPLEXA; PHYLOGENIES; PILCHARDUS; ALGORITHM; MODEL	Phenotypic scrutiny on the life cycle of lcthyodinium chabelardi (Perkinsoide chabelardi n. gen.) based on ultrastructural techniques, and molecular phylogenetic analysis of RNA gene sequences, were carried out in order to elucidate the taxonomic position of this parasite. The absence of plastid, presence of trichocysts, and chromosomes or chromatin condensed and low in number, suggested that this protozoan could be considered a dinoflagellate syndinial parasite. However, the life cycle, schizogonic divisions and structure of schizonts inside the host, the nuclei without the typical dinoflagellate appearance, presence of rhoptrias-like structures, a possible pseudoconoid, and the biflagellated spore, resembled those of the genus Perkinsus. Phylogenetic analysis of genes transcribing for the RNA forming the small subunit and the large subunit suggests that this parasite has an ambiguous evolutionary position within the group formed by dinoflagellates, perkinsids and syndinials. Because of differences with dinoflagellates and similarities with perkinsids, we propose to change the generic name to P chabelardi n. gen. High stationary infection prevalence on Sardina pilchardus eggs was observed. This protozoan parasite caused the death of all the infected sardine eggs, and therefore a high impact in the recruitment of this fishery in the Atlantic coast is expected.

However the study of dinoflagellate chromosomes is not amendable because of the unusually higher number of chromosomes and problems in sample preparation. The species of Pyrocystis spend most of their life cycle as vegetative cyst forms and have been used as experimental organisms for bioluminescence and circadian rhythms. Here, we documented the content of DNA in different life stages and the chromosome karyology in a marine non-motile dinoflagellate Pyrocystis lunula, through light and fluorescent microscopy, serial ultra-thin sectioning, and three dimension (3D) modeling. The DNA content doubles during DNA synthesis and in the end of the cell division two separate daughter cells have the approximately same fluorescent values for the mother cells. Using serial ultra-thin sectioning and 3D modeling, we report the first ultrastructural karyogram. The cells chosen were at the end of karyokinesis. A total of 98 chromosomes were counted and assigned to 49 pairs. In this species, DNA synthesis appears to occur before, or during asexual division and P. lunula lives a diplontic life cycle.

This paper reports on the effects of temperature, nitrogen, and phosphorus on the percentage of encystment of the dinoflagellate Peridinum cinctum Stein. The phosphorus content of the medium affected encystment only at the highest temperature applied (22 degrees C). Nitrogen content and temperature were the most important factors controlling the encystment.

SP.	This review summarizes data on the biogeography and dispersal of bacteria, microfungi and selected protists, such as dinoflagellates, chrysophytes, testate amoebae, and ciliates. Furthermore, it introduces the restricted distribution and dispersal of mosses, ferns and macrofungi as arguments into the discussion on the postulated cosmopolitism and ubiquity of protists. Estimation of diversity and distribution of micro-organisms is greatly disturbed by undersampling, the scarcity of taxonomists, and the frequency of misidentifications. Thus, probably more than 50% of the actual diversity has not yet been described in many protist groups. Notwithstanding, it has been shown that a restricted geographic distribution of micro-organisms occurs in limnetic, marine, terrestrial, and fossil ecosystems. Similar as, in cryptogams and macrofungi about, 30% of the extant supragenefic taxa, described and undescribed, might be morphological and/or genetic and/or molecular endemics. At the present state of knowledge, micro-organism endemicity can be proved/disproved mainly by flagship species, excluding sites (e.g., university ponds) prone to be contaminated by invaders. In future, genetic and molecular data will be increasingly helpful. The wide distribution of many micro-organisms has been attributed to their small size and their astronomical numbers. However, this interpretation is flawed by data from macrofungi, mosses and ferns, many of which occupy distinct areas, in spite of their minute and abundant means of dispersal (spores). Thus, I suggest historic events (split of Pangaea etc.), limited cyst viability and, especially, time as major factors for dispersal and provinciality of micro-organisms. Furthermore, the true number of species and their distribution can hardly be estimated by theories and statistics but require reliable investigations on the number of morphospecies in representative ecosystems. Generally, the doubts on Beijerinck's famous metaphor "in micro-organisms everything is everywhere" can be focussed on a simple question: If the world is teeming with cosmopolitan unicells, where is everybody?

J	Gayoso, AM; Fulco, VK				Gayoso, AM; Fulco, VK			Occurrence patterns of <i>Alexandrium tamarense</i> (Lebour) Balech populations in the Golfo Nuevo (Patagonia, Argentina), with observations on ventral pore occurrence in natural and cultured cells	HARMFUL ALGAE			English	Article						Alexandrium; Argentina; harmful algae blooms; Patagonia	DINOFLAGELLATE; PHYTOPLANKTON; WATERS; SEA	Phytoplankton composition and abundance in the Golfo Nuevo, Argentina, have been studied from 1995 to 2001 along with water-temperature, salinity, nutrient and chlorophyll a concentrations. The pattern of seasonal phytoplankton distribution has shown recurrent blooms of Alexandrium tamarense during late winter and spring characterized by strong interannual fluctuations in magnitude. During October and December 2000, a large number of dead penguins (Spheniscus magellanicus) and other marine birds were found along the shore of Chubut. Coincident with those episodes of bird mortality, a bloom of A. tamarense occurred from October through December 2000. The spatial distribution of A. tamarense was patchy and the population density increased near the coast (maximum 22 x 10 3 cells L-1 in the surface layer). A. tamarense cysts were observed in bottom sediments, and increased in abundance from coastal stations (0-5 cysts cm(-3) of sediment) to the offshore, deeper areas (100300 cysts cm(-3)). Multiple regression analysis Suggests that variations in irradiance may be the major source of temporal variability of A. tamarense in Golfo Nuevo. The relationship of A. tainarense cell abundance and that of the dominant phytoplankton species during the spring was investigated using Pearson correlation. A. tamarense cell abundance was significantly correlated with cell abundances of the dinoflagellates Scrippsiello trochoidea and Prorocentrum micons and negatively correlated with phytoflagellates. The morphological variability of A. tainarense from field populations and in clones grown under different conditions was examined. There was great variability in the presence/absence of the ventral pore (an important character used to distinguish species of Alexandrium). (c) 2005 Published by Elsevier B.V.

The objectives were to determine whether the parental identity influenced the physiological and morphological aspects of the cyst offspring, and to describe and compare nuclear development and cell division of encysting and non-encysting zygotes. Variables characteristic of each parental cross (difference in growth rates among parents, cyst production (CP), and genetic distance (GD) among parents assessed via an amplified fragment length analysis analysis) were studied to seek for possible relationships of the parental crosses with some characteristics of the cyst offspring (cyst size, length of dormancy period, germination success, and germling viability (V)). A principal component analysis using these variables showed three main results: (1) the dormancy period of cysts responded to a simple pattern of inheritance, (2) the larger the GD between parents, the smaller the CP, and progeny V, and (3) the size of cysts was influenced by both CP and the parental strain identity. A stable inheritance of the short dormancy period (14.6 +/- 5.5 days), dominant over medium (31.0 +/- 8.5 days) and long periods (52.7 +/- 9.2 days), was confirmed through two subsequent generations of cysts. The regulation of the sexual processes by a multiple loci system is discussed based on the pattern of inheritance of the dormancy period and the number of sexual recombination events recorded within cultures with self-CP capability. Fusion of the gamete nuclei happened 0-48 h after the total cytoplasmic fusion. The nucleus of the zygote was bilobed and had thick and distinct chromosomes. Similar processes of nuclear and cell division occurred in the non-encysting or encysting planozygote, and were characterized by the loss of the chromosomal structure, an apparent increase of the DNA content, and the formation of thinner chromosomes.

In culture this species formed round, smooth cysts when strains were mixed, indicating heterothallic sexuality and hypnozygote production. However, cysts of the same morphology were also formed in clonal strains exposed to slightly elevated temperature. To better understand the role of cysts in the life cycle of S. hangoei, cyst formation and dormancy were examined in culture experiments and the cellular DNA content of flagellate cells and cysts was compared in clonal and mixed strains using flow cytometry. S. hangoei exhibited a high rate of cyst formation in culture. Cysts produced in both clonal and mixed strain cultures were thick-walled and underwent a dormancy period of 4 months before germinating. The S. hangoei flagellate cell population DNA distributions consisted of 1C, intermediate, and 2C DNA, indicative of respective eukaryotic cell cycle phases G1, S, and G2M. The majority (> 95%) of cysts had a measured DNA content equivalent to the lower 1C DNA value, indicating a haploid nuclear phase and an asexual mode of cyst formation. A small percentage (< 5%) of cysts produced in the mixed strain culture had 2C DNA, and thus could have been diploid zygotes. These findings represent the first measurements of dinoflagellate resting cyst DNA content, and provide the first quantitative evidence for dinoflagellate asexual resting cysts. Asexual resting cysts may be a more common feature of dinoflagellate life cycles than previously thought.
