Description

Plant reproduction relies on transfer of pollen from anthers to stigmas, and the majority of flowering plants depend on biotic or abiotic agents for this transfer. A key metric for characterizing if pollen receipt is insufficient for reproduction is pollen limitation, which is assessed by pollen supplementation experiments. In a pollen supplementation experiment, fruit or seed production by flowers exposed to natural pollination is compared to that following hand pollination either by pollen supplementation (i.e. manual outcross pollen addition without bagging) or manual outcrossing of bagged flowers, which excludes natural pollination. The GloPL database brings together data from 2969 unique pollen supplementation experiments reported in 927 publications published from 1981 to 2015, allowing assessment of the strength and variability of pollen limitation in 1265 wild plant species across all biomes and geographic regions globally. The GloPL database will be updated and curated with the aim of enabling the continued study of pollen limitation in natural ecosystems and highlighting significant gaps in our understanding of pollen limitation.

Notes

GloPL, a global data base on pollen limitation of plant reproduction
The GloPL database brings together data from 2969 unique pollen supplementation experiments reported in 927 publications, allowing assessment of the strength and variability of pollen limitation in 1265 wild plant species across all biomes and geographic regions globally. A case is defined as a comparison of the reproductive output (proportion of flowers setting fruit, proportion seeds per ovule, seeds per fruit, seeds per flower, seeds per plant) of plants receiving hand pollination with those receiving natural pollination. When studies were replicated across sites and/or years at the same site, each unique site and year combination became one case in the dataset. We treated each year and population as a separate data case (i.e., row in the database), as were time periods within a season or multiple morphs (e.g., flower color, gender) within a population and different experimental treatments (e.g., nutrient addition, herbivore exclusion). For each case within the GloPL database, we provide plant taxonomic information and geographic coordinates. Detailed meta-data for each column is located in Table 2 of the Data Descriptor article.
