Dispersal permanence of a periodic predator–prey system with Holling type-IV functional response

摘要

In this paper, we study the permanence of a class of periodic predator–prey system with Holling type-IV functional response where the prey disperses in patchy environment with two patches, and provide a sufficient and necessary condition to guarantee permanence of the system. Finally, two examples are presented to illustrate the application of our main results.
