Historical gene flow constraints in a northeastern atlantic fish: phylogeography of the ballan wrasselabrus bergyltaacross its distribution range
The distribution and demographic patterns of marine organisms in the north Atlantic were largely shaped by climatic changes during the Pleistocene, when recurrent glacial maxima forced them to move south or to survive in northern peri-glacial refugia. These patterns were also influenced by biologica...
