West Virginia stream fish diversity indices

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&nbsp;'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. , , # West Virginia stream fish diversity indices Dataset DOI: [10.5061/dryad.z08kprrsc](10.5061/dryad.z08kprrsc) ## 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 <br /> NA values indicate that there were not enough species (< 3) to calculate the index. **References** Brosse, S., Charpin, N., Su, G., Toussaint, A., Herrera-R, G.

FISHMORPH: A global ..., ,本数据集针对西弗吉尼亚州全域的溪流鱼类群落，计算得到三类多样性指数：物种丰富度（species richness）、功能丰富度（functional richness）与功能分歧度（functional divergence）。所有指数均通过R语言的'FD'包计算完成。研究结合各性状的生态显著性，从FishMorph数据库（FishMorph Database）中选取6项形态学性状用于多样性指数的计算，具体包括：眼部垂直位置、眼部相对位置、口裂位置、胸鳍大小、身体延长度以及尾柄压缩度（caudal peduncle throttling）。 # 西弗吉尼亚州溪流鱼类多样性指数 数据集DOI：[10.5061/dryad.z08kprrsc](10.5061/dryad.z08kprrsc) ## 数据与文件结构说明 本数据集涵盖西弗吉尼亚州溪流鱼类群落的物种丰富度（字段名NumberSpecies）、功能丰富度（字段名FRic）、功能分歧度（字段名FDiv）以及空间位置（经度与纬度），所有指标均通过R语言的'fd'包结合FishMorph数据库的性状计算得到（Brosse等，2021；Laliberté等，2014）。 ### 文件与变量说明 #### 文件：Fish_Diversity_Indices.csv **描述：** 鱼类多样性指数 ##### 变量说明 * NumberSpecies：物种丰富度 * FRic：功能丰富度 * FDiv：功能分歧度 * POR_LON_DD：样地经度 * POR_LAT_DD：样地纬度 <br /> 缺失值（NA）代表样地内物种数量不足3个，无法计算对应指数。 **参考文献** Brosse, S., Charpin, N., Su, G., Toussaint, A., Herrera-R, G.
