Out of the Mediterranean? Post‐glacial colonization pathways varied among cold‐water coral species
Abstract Aim To infer cold‐water corals’ (CWC) post‐glacial phylogeography and assess the role of Mediterranean Sea glacial refugia as origins for the recolonization of the northeastern Atlantic Ocean. Location Northeastern Atlantic Ocean and Mediterranean Sea. Taxon Lophelia pertusa, Madrepora ocul...

In contrast, the stronger genetic differentiation of M. oculata populations mirrors the effects of long‐term isolation in multiple refugia. We suggest that the distinct and genetically divergent, refugial populations initiated the post‐glacial recolonization of the northeastern Atlantic margins, leading to a secondary contact in the northern range and reaching higher latitudes much later, in the late Holocene. This study highlights the need to disentangle the influences of present‐day dispersal and evolutionary processes on the distribution of genetic polymorphisms, to unravel the influence of past and future environmental changes on the connectivity of cosmopolitan deep‐sea ecosystems associated with CWC.
