The effects of environmental gradient and dispersal distance (a) and the effect of the size of mating area (b), carrying capacity (c), the size (horizontal extension) of habitat [x axis] (d), the relative strength of female preference (e), mutation mode, and mutation rate (f) on probability of speciation on probabilities of speciation. G = 0.10 and d = 50 except (a), M = 100 except (b), K = 10 except (c), habitat size = 1000 × 1000 except (d), α = 8 except (e), μ = 0.00001 except and 5 sites mutation model except (d and f), Male nuptial color is controlled by 100 loci. a) M = 100; b) d = 50, G = 0.10, Each cell in (a) and each value in (b) is a mean of 10 replicate simulations. Parameter values used as background in exploration of individual parameter space are highlighted (open circle).
