Abstract:
In this paper, we study the following delayed predator-prey model of prey dispersal in two-patch environments x1 (t) = x1 (t)[r1 (t) -a11 (t)x1 (t)- a13 (t)y(t)] +D(t)(x2 (t)-x1 (t )),x2 (t) = x2 (t)[r2 (t) -a22 (t)x2 (t)- a 23 (t)y(t)] +D(t)(x1 (t)-x2 (t )),y(t) = y(t)[-r3 (t)+ a31 (t)x1 (t -τ1) +a32 (t)x2 (t - τ1)- a33 (t)y(t -τ2)].By giving the detail analyzing of the right-hand side functional of the system, sufficient and necessary condition which guarantee the predator and the prey species to be permanent are obtained. Numeric simulations show the feasibility of main results. In additional to the above, sufficient condition on the permanence of the above system with predator density-independence are established. © 2009 Korean Society for Computational and Applied Mathematics.
