Effects of founding genetic variation on adaptation to a novel resource.

Evolution; international journal of organic evolution - 1 Sept 2011

Agashe Deepa, Falk Jay J, Bolnick Daniel I

Abstract excerpt

Population genetic theory predicts that adaptation in novel environments is enhanced by genetic variation for fitness. However, theory also predicts that under strong selection, demographic stochasticity can drive populations to extinction before they can adapt. We exposed wheat-adapted populations of the flour beetle (Tribolium castaneum) to a novel suboptimal corn resource, to test the effects of founding...
