(Color online) (a) Spatiotemporal pattern of the predator in one-dimensional space for multiple PP model with time-varying migration. (b) Time series of the predator in the 50th subsystem. The maximum environmental carrying capacity K 2 i = 10 and K 2 i − 1 = 5 with i = 1 , 2 , … , 50 , other parameters ε = 0.82 and σ₁ = σ₂ = 0.5.
