Genotype likelihood (beagle file) and genotype (vcf) files of North Atlantic and Black Sea Harbour porpoises (Phocoena phocoena)

The Harbour porpoise (Phocoena phocoena) is a highly mobile cetacean species primarily occurring in coastal and shelf waters across the Northern hemisphere. It inhabits heterogeneous seascapes broadly varying in salinity and temperature. Here we produced 74 whole genomes at intermediate coverage to study Harbour porpoise’s evolutionary history and investigate the role of local adaptation in the diversification into subspecies and populations. We identified ~6 million high-quality SNPs sampled at 8 localities across the North Atlantic and adjacent waters, which we used for population structure, demographic, and genotype-environment association analyses. Our results suggest a genetic differentiation between three subspecies (P.p. relicta, P.p. phocoena, and the recently proposed P.p meridionalis), and three distinct populations within the subspecies P.p. phocoena: Atlantic, Belt Sea, and Proper Baltic Sea. Effective population size and Tajima’s D levels suggest a population contraction in..., , , # Genotype likelihood (beagle file) and genotype (vcf) files of North Atlantic and Black Sea Harbour porpoises (Phocoena phocoena)
