Figure 4From: Investigation on dynamics of an impulsive predator–prey system with generalized Holling type IV functional response and anti-predator behaviorThe numerical simulation demonstrates the occurrence of a stable positive periodic solution of the impulsive system in Eq. (7). Here, the parameter values and the initial condition are exactly the same as used in Fig. 2 except \(T=2.7>T_{\max }=2.47\): (a) the time series simulation of the prey density \(x(t)\); (b) the time series simulation of the predator density \(y(t)\); (c) the trajectory simulation plotted on the xy-planeBack to article page
