Circum-Arctic raw sequence dataset (RAD-sequencing) of Boreogadus saida

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. Through a reduced-representation sequencing approach, this study explored the spatial genetic structure of polar cod (Boreogadus saida) at a circum-Arctic scale. Genomic variation was partitioned into neutral and adaptive components to respectively investigate genetic connectivity and local adaptation.
