Deterministic and stochastic trajectories of prey population and predator population with parameters in Table 1. Moreover, \(\sigma _{1} ^{2}=\sigma _{2}^{2}=0.005\) and \(\gamma _{1}(u)=\gamma _{2}(u)=0.05\). (a) Trajectories of prey population. (b) Trajectories of predator population. (Color figure online)
