Phylogeography of Harbour Porpoise (Phocoena phocoena) in the Eastern North Atlantic and in the Black Sea Explored by the Analyses of Nuclear and Mitochondrial DNA
Study of the genetic population structure and the demographic history of the harbour porpoise (Phocoena phocoena) has been nearly comprehensive throughout its distribution in North Atlantic, most studies using the mitochondrial control region as a genetic marker. Although these studies have shown po...

Study of the genetic population structure and the demographic history of the harbour porpoise (Phocoena phocoena) has been nearly comprehensive throughout its distribution in North Atlantic, most studies using the mitochondrial control region as a genetic marker.
