Multiple paternity increases effective size of southern Atlantic salmon populations
Abstract Genetic analyses were performed on the progeny of Atlantic salmon ( Salmo salar L.) sampled in natural redds of three rivers flowing into the Bay of Biscay, the Nivelle, the Mandeo and the Sella. These rivers are at the southern limit of the European distribution of the species and their po...
