Analysis of an Impulsive One-Predator and Two-Prey System with Stage-Structure and Generalized Functional Response

Figure 3

The permanence of system (3) with initial values of , , , and , and other parameters are the same as those in Figure 1. Obviously, all these species can coexist and their densities go into a bounded region. (a) Time series of , , and , which indicate that the solution of (3) goes into a bounded region to be permanent. (b) Phase portrait of system (3), which implies a positive periodic solution.
