| Abstract: | In this paper we study the stability for equilibrium points of equations in two-population dynamics. We discuss two predator-prey-patch models. Model 1 is described by an differential equation. Model 2 is described by an integral differential equation, we obtain the conditions for the stability of their equilibrium points. The results show that the overall population stability despite local extinction is realizable. |
