摘要：Determining the relative importance of ecological processes regulating the biogeographic patterns of marine species, especially with respect to alpha- and beta-diversity in multi-habitat communities, is a central goal in marine ecology. We explored the relative contribution of spatial (stochastic processes) and environmental factors (deterministic processes) to the biogeographic patterns of the alpha- and beta-diversity of mangrove mollusks. A total of 16 mangrove areas were sampled in southeast coast China from 18 degrees N to 28 degrees N latitude. The highest mean alpha-diversity was found at 20 degrees N and that of beta-diversity was at 21 degrees N. Both spatial and environmental factors had significant effects on the alpha- and beta-diversity patterns. The environments had greater effects than the spaces on shaping the alpha-diversity pattern, while the spaces were relatively more important in governing the beta-diversity patterns than the environments. Our results suggest that the alpha-diversity pattern was mainly controlled by deterministic processes (environmental filtering), while beta-diversity was primarily shaped by stochastic processes (dispersal-related), although both processes had significant impacts on alpha- and beta-diversity patterns. Identifying the ecological variables and mechanisms that drive variations in alpha- and beta-diversity may help guide the conservation for biodiversity in endangered mangrove ecosystems under anthropogenic and global changes.
