Seasonal elevational patterns and the underlying mechanisms of avian diversity and community structure on the eastern slope of Mt. Gongga

This dataset contains bird survey data (Appedenix 2) and bird trait data (Appedenix 1) in the paper: “He et al. (2022) Seasonal elevational patterns and the underlying mechanisms of avian diversity and community structure on the eastern slope of Mt. Gongga. Diversity and Distributions”. Main results of the paper are that TD, PD and FD showed similar hump-shaped elevational patterns in both seasons. In the breeding season, TD, PD and FD for small-ranged species, were highly correlated with climatic factors (mean daily temperature, seasonal temperature range) and vegetation factors (enhanced vegetation index), while large-ranged species were correlated with spatial factors (mid-domain effect). In the non-breeding season, TD, PD and FD for all species groupings were positively correlated with climate factors. For small-ranged species in both seasons, community structure was more overdispersed at low and high elevations, and more clustered at middle elevations. For large-ranged species, com...本数据集包含发表于《多样性与分布（Diversity and Distributions）》的论文《何等（2022）贡嘎山东坡鸟类多样性与群落结构的季节海拔格局及潜在机制》中的鸟类调查数据（附录2，Appendix 2）与鸟类功能性状数据（附录1，Appendix 1）。该论文的主要研究结果显示：分类多样性（Taxonomic Diversity, TD）、系统发育多样性（Phylogenetic Diversity, PD）与功能多样性（Functional Diversity, FD）在两个季节均呈现相似的驼峰状海拔格局。繁殖季中，狭域物种的分类多样性、系统发育多样性与功能多样性与气候因子（日平均温度，mean daily temperature；温度季节变幅，seasonal temperature range）及植被因子（增强型植被指数，enhanced vegetation index）高度相关；而广域物种的上述多样性指标则与空间因子（中域效应，mid-domain effect）相关。非繁殖季中，所有物种类群的分类多样性、系统发育多样性与功能多样性均与气候因子呈正相关。对于两个季节的狭域物种而言，其群落在低海拔与高海拔地区呈现更显著的过度分散格局，而在中海拔地区则更为聚集。对于广域物种而言，群落……
