An assessment of the spatial scale of local adaptation in brown trout (Salmo trutta L.): footprints of selection at microsatellite DNA loci
Meier, K.; Hansen, M.M.; Bekkevold, Dorte; Skaala, Øystein; Mensberg, K-L.D. (Journal article; Peer reviewed, 2011-01-12)Local adaptation is considered a paradigm in studies of salmonid fish populations. Yet, little is known about the geographical scale of local adaptation. Is adaptive divergence primarily evident at the scale of regions or ... -
