Distributional and demographic consequences of Pleistocene glaciations for a marine demersal fish
The Pleistocene glaciations were the most significant historical event during the evolutionary lifespan of most extant species. However, little is known about the consequences of the ice ages on the distribution and demography of marine animals of the Northeastern Atlantic. Because of reduced levels...
