Tropical regions harbour over half of the world's mammals and birds, but how their communities have assembled over evolutionary timescales remains unclear. To compare eco-evolutionary assembly processes between tropical mammals and birds, we tested how hypotheses concerning niche conservatism, environmental stability, environmental heterogeneity and time-for-speciation relate to tropical vertebrate community phylogenetic and functional structure.

进化历史和环境变异结构当代热带脊椎动物群落

热带地区栖息着世界上一半以上的哺乳动物和鸟类，但它们的群落在进化时间尺度上如何聚集仍不清楚。为了比较热带哺乳动物和鸟类之间的生态进化组装过程，我们测试了有关生态位保守性、环境稳定性、环境异质性和物种形成时间的假设如何与热带脊椎动物群落系统发育和功能结构相关。
