Abstract
In this paper, we study the persistence and average persistence of a nonautonomous Kolmogorov type predator-prey system. Sufficient and necessary criteria for the persistence and average persistence are obtained, respectively. In addition, as a special case, we also discuss the equivalence of persistence of several kinds for almost periodic Kolmogorov type predator-prey system.
