Fish data

The file “Fish data” contains 3 Excel spreadsheets, i.e. “Raw data,” “Community data,” and “Species data.” The Raw data spreadsheet shows the abundance, measured as number of individuals, and the abundance rank for all species (BioDataTaxonName) across 761 fish samples, listed by their sample identification. The fish samples were collected from 399 distinct stream localities, listed by their station identification. The Community data spreadsheet contains relevant information for the fish samples, including latitude, longitude, date of collection, species richness, evenness, total abundance (number of individuals), statistics of the Poisson lognormal fit to the sample species abundance distribution (parameters mu and sigma, gof (goodness of fit), and p (proportion of species revealed by the sample)), statistics of the square root fit to the sample rank-abundance distribution (intercept a0, slope a, and their standard errors and 95% confidence intervals), ln Tolerant:Intolerant ratio, and abundance and richness of the three fish tolerance groups (tolerant, intolerant, and moderate). Environmental data were available for a subset of 732 samples. The Species data spreadsheet lists the 460 fish species (BioDataTaxonName) encountered in this study with tolerance group designation whenever known and occurrence across 1005 stream localities.
