Figure 4. Spatial Structure of Coexistence.

For each of the three cases that allow for coexistence in the spatial game (see Figure 2A), a realization of the stochastic process was simulated on a cubic lattice of side length L = 100. The initial field is seeded using a product measure with probabilities 0.2 (R), 0.3 (F) and 0.5 (Q), respectively, and representative 2D cross sections (size: 100 × 100 elements) of the 3D systems are shown after reaching the stationary state. The size of individual lattice elements is not directly specified (see text), but expected to be of the order of 100 microns, as indicated by the bar in the figure. All remaining model parameters as follows. Case 1A α₁ = −0.2, α₂ = −0.1, α₃ = 0.45, β₁ = 0.5, β₂ = 0.1, β₃ = 0.6; Case 4A: α₁ = −0.1, α₂ = −0.5, α₃ = −0.3, β₁ = 0.6, β₂ = 0.3, β₃ = 0.4; Case 4B: α₁ = −0.6, α₂ = −0.6, α₃ = −0.4, β₁ = 0.6, β₂ = 0.2, β₃ = 0.4.
