Allelic variation in a willow warbler genomic region is associated with climate clines
Local adaptation is an important process contributing to population differentiation which can occur in continuous or isolated populations connected by various amounts of gene flow. The willow warbler (Phylloscopus trochilus) is one of the most common songbirds in Fennoscandia. It has a continuous br...

The willow warbler (Phylloscopus trochilus) is one of the most common songbirds in Fennoscandia.

Local adaptation is an important process contributing to population differentiation which can occur in continuous or isolated populations connected by various amounts of gene flow.
