Post‐glacial colonization routes coincide with a life‐history breakpoint along a latitudinal gradient
Abstract Although adaptive divergence along environmental gradients has repeatedly been demonstrated, the role of post‐glacial colonization routes in determining phenotypic variation along gradients has received little attention. Here, we used a hierarchical Q ST – F ST approach to separate the role...
