Aim. To infer cold-water corals' post-glacial phylogeography and assess the role of Mediterranean Sea glacial refugia as origins for the recolonisation of the northeastern Atlantic Ocean. Location. Northeastern Atlantic Ocean and Mediterranean Sea. Taxon. Lophelia pertusa, Madrepora oculata. Methods. We sampled cold-water corals using remotely operated vehicles and one sediment core for coral and sediment dating. We characterized spatial genetic patterns (microsatellites and a nuclear gene fragment) using networks, clustering and measures of genetic differentiation. Results. Inferences from microsatellite and sequence data were congruent, and showed a contrast between the two cold-water coral species. Populations of L. pertusa present a dominant pioneer haplotype, local haplotype radiations and a majority of endemic variation in lower latitudes. M. oculata populations are differentiated across the northeastern Atlantic and genetic lineages are poorly admixed even among neighbouring sites. Conclusions. Our study shows contrasting post-glacial colonisation pathways for two key habitat-forming species in the deep-sea. The cold-water coral L. pertusa has likely undertaken a long-range (post-glacial) recolonisation of the northeastern Atlantic directly from refugia located along southern Europe (Mediterranean Sea or Gulf of Cadiz).
