Phylogeographic Estimates of Colonization of The Deep Atlantic by The Protobranch Bivalve Nucula Atacellana
Abstract The Pleistocene and post-Pleistocene evolutionary history of many North Atlantic intertidal invertebrate species is well known, but the evolutionary history of the deep North Atlantic fauna is poorly understood, specifically whether colonization of the deep North Atlantic paralleled the pat...
