Effects of the density-dependent dispersal on population dynamics

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.
