Abstract:
In this paper, the effect of diffusion on the permanence
and extinction in the polluted environment is studied
by a single population diffusive system in two patches.
Assume that the two patches are a protective patch and a
non-protective patch. We examine the effects of protective
patch and conclude that it is effective for the conservation
of a population facing polluted environment. The conditions
for the permanence and extinction of the population are obtained.
