報告摘要：Dispersal strategies, predation and competition are main determinants shaping the structure and functioning of ecological communities and maintaining the biodiversity. Most of existing models describing the predator-prey or completion dynamics employ the random dispersal strategy. However, biological species will more likely use non-random dispersal to optimize their ecological fitness in changing environments. Among other things, in this talk, we shall discuss how density-dependent dispersal (meaning that the dispersal of one species depends on the densities of other species), as a non-random dispersal strategy, may influence population dynamics in various ecological processes, and explore how it is selected to promote species coexistence and hence increase species richness and diversity.
