High gene flow in polar cod (<scp> Boreogadus saida </scp>) from <scp>West‐Svalbard</scp> and the Eurasian Basin
Abstract The current and projected environmental change of the Arctic Ocean contrasts sharply with the limited knowledge of its genetic biodiversity. Polar cod Boreogadus saida (Lepechin, 1774) is an abundant circumpolar marine fish and ecological key species. The central role of polar cod in the Ar...
