分离分布如何产生以及生物体多样化模式为何不同仍然是生物地理学中最引人注目的基本问题。我们对泛热带地钱属 Ceratolejeunea 进行了系统发育地理学分析,以确定其地理起源及其获得新热带-非洲分离的传播路线。此外,我们还调查了岛屿上的 Ceratolejeunea 是否存在地理结构,以及岛屿多样性是否是辐射或经常性迁徙的结果。
How disjunct distributions arise and why organisms differ in diversification patterns remain some of the most compelling fundamental questions in biogeography. We carry out phylogeographical analyses of the pantropical liverwort genus Ceratolejeunea to identify its geographical origin and the dispersal routes by which it gained its Neotropical‐African disjunction. Furthermore, we investigate whether there is geographical structure in Ceratolejeunea on islands and whether island diversity is a result of radiations or recurrent migration.
