Patterns of species richness along elevation gradients vary with geographic and environmental factors but evidence for similar variation in functional and phylogenetic diversity remains scarce. Here, we provide the most comprehensive evaluation to date of elevational gradients in taxonomic, functional, and phylogenetic diversity of rodents – one of the most ecologically diverse groups of mammals – and test the effects of latitude and aridity on their variation for the first time.

潮湿和干旱山区啮齿动物的海拔多样性模式不同

沿海拔梯度的物种丰富度模式因地理和环境因素而异，但功能和系统发育多样性相似变化的证据仍然很少。在这里，我们提供了迄今为止最全面的啮齿动物分类学、功能和系统发育多样性的海拔梯度评估——啮齿动物是生态上最多样化的哺乳动物群体之一——并首次测试了纬度和干旱对其变异的影响。
