Greater climate change adaptation potential in populations of Quercus macrocarpa at edges of latitudinal gradient.

Abstract excerpt

With current climate trajectories, tree populations will encounter novel selection pressures that risk local extinction if they are unable to acclimate or adapt. Within a reciprocal transplant experiment with Quercus macrocarpa L. established across a latitudinal gradient, we asked: (1) Is there genetic variation within populations? (2) Are there differences in the direction and strength of selection? (3) Do...
