SPARTIAL HETEROGENEITY, FAST MIGRATION AND COEXISTENCE OF INTRAGUILD PREDATION DYNAMICS

Tóm tắt báo cáo

We investigate effects of spatial heterogeneous environment and fast migration of individuals on coexistence of the intraguild predation (IGP) dynamics. We present a two-patch model. We assume that on one patch two species complete for a common resource, and on the other patch one species can capture the other one for the maintenance. We also assume IGP individuals are able to migrate between two patches and the migration process acts on a fast time scale in comparison with demography, predation and competition processes. We show that under certain conditions the heterogeneous environment and fast migration can lead to coexistence of the two species.
