Genetic and phenotypic divergence between low- and high-altitude populations of two recently diverged cinnamon teal subspecies.

Abstract excerpt

Spatial variation in the environment can lead to divergent selection between populations occupying different parts of a species' range, and ultimately lead to population divergence. The colonization of new areas can thus facilitate divergence in beneficial traits, yet with little differentiation at neutral genetic markers. We investigated genetic and phenotypic patterns of divergence between low- and...
