Data from: Decade-long bird trends in China: Stable species richness but increasing biotic homogenization حسب Jiekun He (20964269)

"…Bird communities in regions with pronounced precipitation seasonality and lower elevation exhibited larger increases in species and functional richness, whereas those at higher elevations and topographic heterogeneity showed greater biotic turnover through time. Our results reveal asynchronous changes in taxonomic and functional diversity, and decoupled trends in alpha and beta diversity, implying that stable species richness at the local scale may mask broader-scale trends in functional diversity and biotic homogenization. …"
