Figure 4.
Effect of varying extinction debts ε and ostracism strengths wmax on transient dynamics and stability, for two initial proportions of conformers q(0). Cases (U), (U/M) and (U/S) correspond to the ostracism functions defined in figure 2a, with similar initial conditions, namely H(0) = 0.5, B(0) = (1 − H(0)/ϕ(q))z and q(0) = 0.2 or q(0) = 0.6. (a) low extinction debt (ε = 0.1); (b) intermediate extinction debt (ε = 0.0025); (c) large extinction debt (ε = 0.0005); green dot: (stable) sustainable equilibrium; red dot: (stable) unsustainable equilibrium; blue dot: (stable) mixed equilibrium; transient trajectories are represented by the blue curves. See electronic supplementary material, table S1 for other parameter values.
