Urban parks are important for biodiversity conservation in urban ecosystems. Many natural and anthropogenic factors are associated with bird diversity in urban parks. However, so far no studies have compared the relative roles of these factors in shaping bird taxonomic, phylogenetic and functional diversity in urban parks in whole China. In this study, we linked anthropogenic variables (NDVI, population density, park area) and natural variables...
