Population structure of Atlantic salmon ( Salmo salar L.): a range‐wide perspective from microsatellite DNA variation
Abstract Atlantic salmon ( n = 1682) from 27 anadromous river populations and two nonanadromous strains ranging from south‐central Maine, USA to northern Spain were genotyped at 12 microsatellite DNA loci. This suite of moderate to highly polymorphic loci revealed 266 alleles (5–37/locus) range‐wide...
