Population genomics reveals repeated signals of adaptive divergence in the Atlantic salmon of north‐eastern Europe
Abstract Our ability to examine genetic variation across entire genomes has enabled many studies searching for the genetic basis of local adaptation. These studies have identified numerous loci as candidates for differential local selection; however, relatively few have examined the overlap among ca...
