Nontrivial Effect of Time-Varying Migration on the Three Species Prey-Predator System |
(Color online) The critical parameter εc as a function of σ1 for σ2 = 0.5 (a) and as a function of σ2 for σ1 = 0.8 (b). Other parameters in the two-system model with migration are fixed as K1 = 10, K2 = 5, rx = 0.55, ry = 0.71, h = 1.48, λ = 0.68, d = 0.485, and α = β = 0.02. |
