Information on connectivity and genetic structure of marine organisms remains sparse in frontier ecosystems such as the Arctic Ocean. Filling these knowledge gaps becomes increasingly urgent, as the Arctic is undergoing rapid physical, ecological and socio-economic changes. The abundant and widely distributed polar cod (Boreogadus saida) is highly adapted to Arctic waters, and its larvae and juveniles live in close association with sea ice. ...

Temperatures in the Arctic are rising three times faster than the global average, resulting in a rapid decline in sea-ice, and lengthening of the ice-free season. As sea ice retreats, fishing grounds that were previously not accessible will inevitable open up and shipping activities in the Arctic will increase together with the potential of accidental oil spills into the marine ecosystem. Environmental changes, together with increased ...

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 Arctic marine food web warrants a better understanding of its population structure and connectivity. In this study, the genetic population structure of 171 ...
