Local adaptation and the evolution of phenotypic plasticity in Trinidadian guppies (Poecilia reticulata).

Abstract excerpt

Divergent selection pressures across environments can result in phenotypic differentiation that is due to local adaptation, phenotypic plasticity, or both. Trinidadian guppies exhibit local adaptation to the presence or absence of predators, but the degree to which predator-induced plasticity contributes to population differentiation is less clear. We conducted common garden experiments on guppies obtained from...
