Title: On competition of species with different diffusion strategies

Abstract: Evolutionary survival and extinction of species are strongly influenced by their intrinsic properties (such as the growth rate and the carrying capacity) and a smart choice of a dispersal strategy. We study the interaction between two species choosing different types of movement in a heterogeneous environment, where in addition intrinsic growth rates and carrying capacities can be different. We also consider the case when the choice of dispersal strategies guarantees coexistence, and compare different diffusion strategies. Generally, higher diffusion coefficients are detrimental while higher growth rates, as well as lower resources sharing, are beneficial for population survival.
