Adaptation at the edge: Patterns of local adaptation and genetic variation during a contemporary range expansion.

Abstract excerpt

During range expansion, differences can evolve between populations at the core and expanding edge of a range. Theory and experiments often focus on range expansions across uniform environments, but in nature, many range expansions occur over environmental gradients that present novel selection pressures. We study phenotypic evolution at the core and edge of a range expansion across a gradient, and the expression...
