摘要：We study the dynamics of two-species Lotka-Volterra competition patch models. The populations are supposed to live in a stream environment, where they are subject to both random dispersal and directed drift. We suppose that one species is a resident species and study the conditions on the parameters under which the other species can or cannot invade. We show that factors such as the magnitude of random dispersal rates and drift rates, the distribution of resources, and the convexity of the drift rates may significantly affect the competition outcomes of the species.
