I investigated the historical basis for variation in regional species diversity. I used a molecular phylogenetic analysis within a single genus of birds (the Old World leaf warblers, genus Phylloscopus) in conjunction with ecological studies in Europe, the Himalayas, and Japan to evaluate the importance of historical events in shaping the present constellation of morphology and behavior in the three different regions. The relatively depauperate assemblages have different histories. In Japan, there was invasion of several lineages, which have more closely related species elsewhere in Asia, whereas in Europe there was also limited in situ speciation. Much of the structure of peripheral communities is attributable to invasions from species-rich Asia, with little in situ morphological diversification. Within the Phylloscopus there are several phylogenetic clades with nonoverlapping size distributions. Major ecological and morphological shifts occurred early in the history of diversification within the group, and rarely since.
我研究了区域物种多样性变化的历史基础。我在一个鸟类单属（旧大陆柳莺属，Phylloscopus）内进行了分子系统发育分析，并结合在欧洲、喜马拉雅地区和日本的生态学研究，以评估历史事件在塑造这三个不同地区当前形态和行为组合方面的重要性。相对物种贫乏的群落有着不同的历史。在日本，有几个谱系的入侵，这些谱系在亚洲其他地方有亲缘关系更近的物种，而在欧洲也有有限的原地物种形成。周边群落的许多结构归因于来自物种丰富的亚洲的入侵，原地形态多样化很少。在柳莺属内有几个系统发育分支，其大小分布不重叠。主要的生态和形态转变发生在该类群多样化历史的早期，此后很少发生。
