Nonlinear eco-evolutionary games with global environmental fluctuations and local environmental feedbacks

Fig 6

Game-environment evolution under different sizes of group N and distribution ratio of the expected total payoffs of the cooperators and defectors θ.

Trajectories on x − r_c phase plane eventually evolve to x* = 0, or circulate along an interior closed orbit, which are distinguished by blue, pink and orange, respectively. Panels (a) and (b) correspond to N = 5 and 6 with θ = 0.5, r_d = 0.6, T = 2π and ϵ = 9, while panels (c) and (d) correspond to θ = 1 and 1.5 with N = 4, r_d = 1, T = 10π and ϵ = 6. In all panels, α = 1.5, β = 3.5.
