Canalization Versus Developmental Conversion in a Spatially Variable Environment

摘要: A model is presented for the evolution of developmental control in a spatially variable environment. Individuals are assumed to disperse at random into one two patches (one harsh and other benign) use three strategies production discrete morphological types. Two unconditional (develop as either stress-tolerant or nontolerant morph), third strategy depends on Invasion criteria used determine conditions under which each pure evolutionarily stable population expected contain some mixture these equilibrium. The results demonstrate that environmental development requires cost morphology, average probability making right choice greater than 50%. range patch frequencies over increases with these...
