- Title
Effects of Protection Zone and Nonlinear Growth on a Predator-Prey Model.

- Abstract
In this paper, we are concerned about a predator-prey model with a protection zone for the prey and nonlinear growth rate for the predator. Global bifurcation, uniqueness and stability of the positive steady-state solution are given as well as the related dynamical behavior. Our study shows that there exists a critical growth rate of the prey, which depends on the protection zone and its diffusion coefficient. If the protection zone is suitably small, then the prey cannot be saved effectively and it may become extinct as the death rate of the predator is small; whereas, if the protection zone is appropriately large, then the prey persists and may coexist with the predator even though the death rate of the predator is small. In addition, it is shown that the nonlinear growth enlarges the coexistence region of the prey and predator.
