Latitudinal variation in speciation mechanisms in frogs.

Evolution; international journal of organic evolution - 1 Feb 2010

Hua Xia, Wiens John J

Abstract excerpt

Speciation often has a strong geographical and environmental component, but the ecological factors that potentially underlie allopatric and parapatric speciation remain understudied. Two ecological mechanisms by which speciation may occur on geographic scales are allopatric speciation through niche conservatism and parapatric or allopatric speciation through niche divergence. A previous study on salamanders found...
