Rich Dynamics of a Predator-Prey System with Different Kinds of Functional Responses

Figure 8

Phase portrait diagram of the predator-prey system (19) with Beddington–DeAngelis-type response function at the coexisting singular point (green filled circle) with initial values . Black line is the predator isocline, and the red curve is the prey isocline. (a); (b), and rest of the parameters are specified as , , , , , , and .
