Dynamical Behavior of a Stochastic Delayed One-Predator and Two-Mutualistic-Prey Model with Markovian Switching and Different Functional Responses

Figure 5

The subgraphs (a), (b), (c), and (d) denote the discrete point distribution of two subsystems and the overall system in , , , and , respectively. The blue, green, and red areas represent the overall system (5), subsystem (64), and subsystem (65), respectively. The green area which means stochastic permanence is far away from the origin while most points of the red area which means extinction lie in the origin. Under the control of Markov chain, the blue area also keeps away from the origin and means stochastic permanence in Case of Example 1.
