Our paper on sea-level driven coastal refugia published in Proceedings of the Royal Society. Here’s a brief, lay summary of our findings.

The last glaciation shaped the genetics of terrestrial species through isolation of populations in ice-free refuges. We demonstrate that glacial-age refuges formed along sub-tropical coasts far from ice, and that these refuges shaped the genetics of coastal marine species too. Continental glaciers remove water from the ocean, lowering sea level and dramatically altering the distribution of coastal habitats. Continental shelves steepen towards their edges, consequently habitats that require shallow slopes, such as estuaries, become rare and isolated during glacially-driven low sea level. These habitats become more widespread and genetically interconnected during interglacials–recapitulating glacial refuge dynamics known from terrestrial species.
