Abstract
Diversity indices (species richness, functional richness, and functional divergence) calculated for stream fish communities across the state of West Virginia. Indices were calculated using the 'FD' package in R. Six morphological traits from the FishMorph database were chosen to calculate the diversity indices based on their ecological significance: vertical eye position, relative eye position, oral gape position, pectoral fin size, body elongation, and caudal peduncle throttling.

Description of the data and file structure
This data includes measures of Species Richness (NumberSpecies), Functional Richness (FRic), Functional Divergence (FDiv), and spatial locations (Longitude and Latitude) of stream fish communities in West Virginia, calculated using the 'fd' package in R and traits the FishMorph database (Brosse et al. 2021, Laliberté et al. 2014).
Files and variables
File: Fish_Diversity_Indices.csv
Description: Fish Diversity Indices
Variables
- NumberSpecies: Species Richness
- FRic: Functional Richness
- FDiv: Functional Divergence
- POR_LON_DD: Site Longitude
- POR_LAT_DD: Site Latitude
NA values indicate that there were not enough species (< 3) to calculate the index.
