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

Fig 2

Effects of varying modeling parameters on equilibrium states of local game-environment evolution in static global environments.

Panel (a) shows the combined influence of w and r_d on the stability of the boundary fixed point (1, α). Panel (b) and (c) show the detailed influence of group size N on the equilibrium states revealed by and ϵ*, respectively. Panel (d) presents the trends of the interior fixed point as θ changes (the dashed blue line indicates that the value of is out of parameter range [α, β]). Panel (e) and (f) show how the threshold of the relative feedback speed ϵ*, which is the minimum value leading to the interior stability, is affected by different parameters. Parameters: N = 4 in (a, d-f), α = 1.5, β = 3.5 in (a, c, e) and r_d = 0.8 in (f).
