ABSTRACT

Biotic populations are usually distributed heterogeneously in their habitat, and the distribution itself is often patchy, due to the patchiness of the habitat which arises from a variety of mechanisms and processes under various conditions including deforestation in the case of a forest habitat. It would thus seem natural to study the population dynamics of a single species by including diffusional effects, in a patchy habitat. Many investigators [40, 41, 44, 55] have shown that in a homogeneous habitat, the diffusion, increases the stability of a system. But these may not always be true if the habitat is patchy [47, 54, 57, 162].
