Population genetics meets phylogenetics: new insights into the relationships among members of the genus Euthynnus (family Scombridae)
Abstract Euthynnus (family Scombridae) is a genus of marine pelagic fish species with a worldwide distribution that comprises three allopatric species: E. alletteratus , E. affinis and E. lineatus . All of them targeted by artisanal and commercial fisheries. We analyzed 263 individuals from Atlantic...
