ESS sex ratios in GOOD habitats ( G ), POOR habitats ( P ) and in the whole population ( SR _tot ) as a function of female dispersal rate ( d _f ) in the model with total density-dependent regulation. (a): g = 0.3. (b): g = 0.7. Bars show maximal and minimal values in 20,000 generations at the equilibrium. Triangles: G, squares: P, and circles: SR _tot . Plain symbols: F = 1.4, open symbols: F = 2. Results are shown for simulations run with initial allele values of G₁,G₂,P₁ and P₂ = 0.5.
