Figure 2From: Dynamics of a stochastic non-autonomous predator-prey system with Beddington-DeAngelis functional responsePrey is weakly persistent in the mean, predator goes to extinction. Solutions of system (3) for α 2 (t)=0.4+0.04sint, β 2 (t)=0.8+0.04sint, with step size Δt=0.05>0. Prey and predator populations are represented by red line and blue line with a star, respectively.Back to article page
