Coevolutionary dynamics of phenotypic diversity and contingent cooperation
Fig 5
Cooperation level, the optimal phenotypic diversity of cooperative strain as a function of θ and β, respectively.
The overall cooperation level decreases with θ. So does the optimal diversity. Even when cooperation is disfavored, the optimal diversity of all cooperative strains still exists. Quite differently, there exists an optimal selection intensity at which the overall cooperation level arrives at the highest and, correspondingly the optimum of diversity level is maximized. Parameters: N = 20, b = 1, c = 0.3. In panels A and B β = 0.1. In panels C and D θ = 0.1.
