Data for RECONCILING ECOGEOGRAPHICAL RULES: RAINFALL AND TEMPERATURE PREDICT GLOBAL COLOUR VARIATION IN THE LARGEST BIRD RADIATION

File species.level.data.csv contains climatic/environmental variables (annual mean temperature, annual precipitation, percent tree cover, mean temperature of warmest quarter, precipitation of warmest quarter) obtained based on each passerine species breeding range and male and female plumage lightness. Species name (TipLabel) matches nomenclature at www.birdtree.org. Also provided are mid latitude for each species' range and taxonomic family.<br>File assemblage.level.data contains for each ~100x100km cell assemblage: average annual mean temperature, average annual precipitation, average percent tree cover, and average male and female passerine plumage lightness. Also included are each cells' mid latitude and longitude, its zoogeographic realm (terrestrial_realm) and number of species of passerines found in it (species_richness)

species.level.data.csv 文件包含基于每种雀形目鸟类（passerine）繁殖范围及雌雄羽色亮度提取得到的气候与环境变量，具体涵盖年平均气温、年降水量、树木覆盖率、最热季平均气温以及最热季降水量。该文件中的物种名称（TipLabel）与www.birdtree.org平台的命名规范保持一致。此外还提供了各物种分布范围的中纬度信息，以及其所属的分类学科别。<br>assemblage.level.data 文件为群落水平数据集，涵盖每个约100×100km栅格单元的相关统计指标：年平均气温均值、年降水量均值、树木覆盖率均值，以及雀形目鸟类雌雄羽色亮度的平均值。此外还包含各栅格单元的中纬度、中经度信息，其所属的陆地生物地理区（terrestrial_realm），以及该单元内记录的雀形目鸟类物种丰富度（species_richness）。
