The Dynamical Analysis of a Prey-Predator Model with a Refuge-Stage Structure Prey Population

We proposed and analyzed a mathematical model dealing with two species of prey-predator system.It is assumed that the prey is a stage structure population consisting of two compartments known as immature prey and mature prey.It has a refuge capability as a defensive property against the jeep liberty fender flare predation.The existence, uniqueness, and boundedness of the solution of the proposed model are discussed.All the feasible equilibrium points are determined.

The local and global stability analysis of them are investigated.The occurrence of local bifurcation (such as saddle node, transcritical, and pitchfork) near each storm pourers of the equilibrium points is studied.Finally, numerical simulations are given to support the analytic results.
