| predation and the maintenance of color polymorphism in a habitat specialist squamate. | multiple studies have addressed the mechanisms maintaining polymorphism within a population. however, several examples exist where species inhabiting diverse habitats exhibit local population-specific polymorphism. numerous explanations have been proposed for the maintenance of geographic variation in color patterns. for example, spatial variation in patterns of selection or limited gene flow can cause entire populations to become fixed for a single morph, resulting in separate populations of th ... | 2012 | 22295080 |
