摘要
The species composition of a biological community results from the interplay between evolutionary and ecological processes(Ricklefs 1987).It depends on the availability of species in the species pool of the region where the community is located,the dispersal ability of species in the regional species pool that allows them to reach the community and the degree to which the species that have reached the community can tolerate abiotic and biotic conditions in the locality(Willis et al.2010).However,evolutionary and ecological processes assembling species into biological communities have generally been studied in isolation from one another(Johnson and Stinchcombe 2007).In the face of widespread and various anthropogenic threats to biological communities worldwide,it is urgent to understand how evolutionary and ecological processes interplay to generate and maintain biodiversity patterns and species membership in biological communities across the globe.
