Abstract excerpt

Brown trout (Salmo trutta) has adapted to a wide range of habitats and displays a variety of life-history strategies. Being facultatively anadromous, populations without migration barriers to the sea consist of both resident and anadromous individuals in different proportions. This affects genetic drift and the level of gene flow between populations, and therefore shapes the metapopulation structure. Here,...
