Glacial survival or late glacial colonization? Phylogeography of the root vole ( Microtus oeconomus) in north‐west Norway
Abstract Aim It has been proposed that the root vole subspecies, Microtus oeconomus finmarchicus , survived the last glacial period on islands on the north‐west coast of Norway. The Norwegian island of Andøya may have constituted the only site with permanent ice‐free conditions. Geological surveys a...
