DATA & FILE OVERVIEW Files File 1 Ecological Metrics.csv: This file contains both continuous and binary trait state variables for reproductive, trophic, and habitat traits in minnow species collected in the Bayou Pierre, Mississippi. File 2 Contemporary Samples.csv: This file documents fishes collected at 41 collection localities throughout the Bayou Pierre watershed, and includes latitude and longitude of collection localities. File 3 Paired Historic and Contemporary Samples.csv: This file documents paired samples through three time periods (1974-75, 1985-89, and 2019-20) at 12 sample localites in the Bayou Pierre. Sample locality numbers match those in File 2 Contemporary Samples.csv.

File 2 Contemporary Samples.csv Fishes were collected by single-pass seining (3mm mesh). We sampled reaches 30x wetted stream widths, bounded between 150 and 300m. We attempted to sample all microhabitats in proportion to their occurrences. All specimens which were small enough to fit into a 2-L sample jar were preserved, larger specimens were photographed for future verification of identification. All preserved specimens were accessioned into the University of Southern Mississippi Ichthyological Collections. The manuscript which utilizes these data focused on minnows (Cyprinidae + Leuciscidae), and this dataset has been filtered to those species. File 3 Paired Historic and Contemporary Samples.csv Historic samples were initially identified through queries of museum data at the University of Southern Mississippi and literature searches. For museum data, we examined field notes for evidence of fishes released in the field. We excluded museum samples which contained < 3 taxonomic families or < 6 species, or which made references to sampling methods other than seining. This filtering was conducted due to a known sampling effort occurring the 1980s and 1990s which used a different sampling methodology targeting the endemic Bayou Darter, and which were known to not be full community datasets. Samples from 1974/1975 were collected as part of an MS thesis project (Matthews, 1978). Specimens for this effort were largely not deposited in museum samples, and only total sums of individuals by species and sample locality were reported. The fish data we deposit here has been similarly summed by species and locality within a time period to provide data comparability. The manuscript which utilizes these data focused on minnows (Cyprinidae + Leuciscidae), and this dataset has been filtered to those species.
