Figure 2. Examples of population dynamics of the prey (black) and of the predator (grey) when spatial heterogeneity is maximal (α = 1).

Metacommunities have two patches (M = 2), one poor patch (left column), where prey carrying capacity (K₁) is kept constant, and one enriched patch (right column), where prey carrying capacity (K₂ =  K₁+E) is increased. A. Low dispersal (d_N = 0.001) and low enrichment (K₂ = 30). B. High dispersal (d_N = 1000) and low enrichment (K₂ = 30). C. High dispersal (d_N = 1000) and high enrichment (K₂ = 40). These three cases correspond to the three points labeled respectively A, B and C on the panels of the Figure 3. Other parameters values: r = 10, K₁ = 18.3, e = 0.1, a = 5, t_h = 0.01, m = 1, d_P =  d_N.
