Character displacement is the term used to describe an evolutionary change that occurs when two similar species inhabit the same environment. Under such conditions, natural selection favors a divergence in the characters--morphology, ecology, behavior,...

Character displacement refers to the phenomenon where differences among similar species whose distributions overlap geographically are accentuated in regions where the species co-occur but are minimized or lost where the species’ distributions do not...

Realistic models for ecological character displacement should incorporate population genetics. In Slatkin's pioneering model (Slatkin 1980), the genetics of the quantitative character determining the competitive interactions are modeled by assuming that the character is normally distributed in each generation. Only the mean and the...

The four different assemblages of marsupial dasyuroid carnivores in Australia, comprising four species on the island of Tasmania and three different two-species assemblages on the mainland of Australia, present an ideal opportunity to test the theories of competitively based morphological character displacement. With males...
