Figure 2From: Analysis of a stochastic predator–prey system with fear effect and Lévy noisePopulation state diagram of system (1.2). (a) and (b) represent time evolution of the prey and predator populations respectively of system (1.2); the only difference from system (1.3) is that there is no Lévy noise. Compared with Fig. 1, we can find that Lévy noise promotes the survival of speciesBack to article page
