摘要：

In this paper, we consider the effect of diffusion on the species that live in changing patches environment. Different from the former studies [1-4], we pay attention to the more important situation in conservation biology that species live in a weak patches environment, in the sense that species in some of the isolated patches will be extinct without the contribution from other patches. We obtain an interesting result: the identical species can persist for some diffusion rates, and can also vanish for another set of restriction on diffusion rates. (C) 1998 Elsevier Science Ltd.
