摘要

Mammals play a crucial role in maintaining ecosystem stability. Understanding their diversity patterns and associated factors is fundamental to ecological and conservation biology research. However, large-scale spatial analyses on mammal diversity distribution remain scarce, particularly in relation to taxonomic characteristics, functional traits and phylogenetic structure. Here, we linked these three dimensions of mammal diversity with geographic gradients and examined their key drivers across mainland China. We compiled a camera trap dataset on terrestrial mammals in mainland China from 281 published articles (2012–2022), including 210 mammal species across 212 sites and accounting for 28.5% of all Chinese mammal species. Taxonomic and functional richness showed a decreasing pattern as latitude increased in China, while functional divergence exhibited a positive relationship with longitude. All three dimensions of mammal diversity, not only overall and conservation priority species richness, but also the traits and evolutionary heritage they represent, were significantly higher within protected areas. These diversity dimensions were also positively associated with terrain ruggedness, supporting the habitat heterogeneity hypothesis. Additionally, we found that larger areas were associated with greater taxonomic diversity. Our research provides a valuable reference for understanding mammal diversity patterns and highlights the importance of incorporating taxonomic, functional and phylogenetic information in biodiversity conservation.
