The population-dispersal dynamics for predator–prey interactions and two competing species in a two patch environment are studied. It is assumed that both species are mobile and their dispersal between patches is directed to the higher fitness patch. It is proved that such dispersal, irrespectively of its speed, cannot destabilize a locally stable predator–prey population equilibrium that corresponds to no movement at all. In the case of two competing species, dispersal can destabilize population equilibrium.
