Local selection across a latitudinal gradient shapes nucleotide diversity in balsam poplar, Populus balsamifera L.

Abstract excerpt

Molecular studies of adaptive evolution often focus on detecting selective sweeps driven by positive selection on a species-wide scale; however, much adaptation is local, particularly of ecologically important traits. Here, we look for evidence of range-wide and local adaptation at candidate genes for adaptive phenology in balsam poplar, Populus balsamifera, a widespread forest tree whose range extends across...
