One of the main goals of functional biogeography is to examine distribution patterns of trait diversity, and islands provide excellent study cases for this emerging field. We tested the hypothesis that multiple dispersals from a common mainland pool would promote functional similarity among island systems when environmental conditions are similar, but also novel phenotypic traits related to colonization history and exploitation of new habitats.

叶片功能性状和岛屿定植：亚热带岛屿作为广泛植物谱系中性状多样性的熔炉

功能生物地理学的主要目标之一是检查性状多样性的分布模式，而岛屿为这一新兴领域提供了很好的研究案例。我们测试了以下假设：当环境条件相似时，来自共同大陆池的多次扩散将促进岛屿系统之间的功能相似性，而且还提出了与殖民历史和新栖息地开发有关的新表型特征。
