Understanding how biodiversity components are related under different environmental factors is a fundamental challenge for ecology studies, yet there is little knowledge of this interplay among the biotas, especially small mammals, in karst mountain areas. Here, we examine the elevation patterns of the taxonomic diversity (TD), phylogenetic diversity (PD) and functional diversity (FD) of small mammals in a karst mountain area, the Wuling Mountains, Southwest China, and compare these patterns between taxa (Rodentia and Eulipotyphla) and scales (broad- and narrow-range species). We also disentangle the impacts of the human influence index, net primary productivity (NPP), normalized difference vegetation index (NDVI), annual precipitation (AP), and annual mean temperature (AMT) on these three facets of biodiversity by using structural equation modeling. We recorded a total of 39 small mammal species, including 26 rodents and 13 species of the order Eulipotyphla. Our study shows that the fa...探明不同环境因子下各生物多样性组分间的关联机制，是生态学研究的核心难题之一，但目前学界对喀斯特山地生物群系（尤其是小型兽类）间的此类相互作用关系仍知之甚少。本研究以中国西南武陵山脉这一喀斯特山地为研究区域，剖析了小型兽类的分类多样性（taxonomic diversity, TD）、系统发育多样性（phylogenetic diversity, PD）与功能多样性（functional diversity, FD）的海拔分布格局，并对比了啮齿目（Rodentia）与真盲缺目（Eulipotyphla）两类类群，以及广布种与狭布种两个尺度下的格局差异。本研究同时借助结构方程模型，厘清了人类影响指数、净初级生产力（net primary productivity, NPP）、归一化植被指数（normalized difference vegetation index, NDVI）、年降水量（annual precipitation, AP）及年平均气温（annual mean temperature, AMT）对上述三类生物多样性维度的影响效应。本研究共记录到小型兽类39种，其中啮齿目26种、真盲缺目13种。本研究显示，该动物群（fauna）的
