Genetic structure and population dynamics of wreckfish (Polyprion americanus) in the North Atlantic
The wreckfish Polyprion americanus is a long-living pelagic fish with a demersal adult phase that shows an antitropical distribution along the Atlantic Ocean, the Indian Ocean and the Pacific Ocean. Previous genetic studies have suggested a significant differentiation between North Atlantic and Sout...
