Figure 3From: Persistence and extinction for stochastic delay differential model of prey predator system with hunting cooperation in predatorsNumerical simulations of the solutions for system (17) and the corresponding deterministic system (2), when \(\mathcal {R}_{0}^{s}<1\) with \(a=0.19\), \(\mu=0.8\), \(\alpha=0.1\), \(c=0.8\), \(K=1\), \(\delta=0.59\), \(r=1\), \(\sigma_{1}=0.001\), \(\sigma_{2}=0.023\), and \(\tau _{1}=\tau_{2}=0.1\). Predator population goes to extinction at \(t=70\) for the deterministic system; while extinction occurs at \(t=20\) with the stochastic modelBack to article page
