Mitochondrial phylogeography and population history of pine martens Martes martes compared with polecats Mustela putorius.

摘要: The flora and fauna of Europe are linked by a common biogeographic history, most recently the Pleistocene glaciations that restricted range species to southern refugial populations. Changes in population size migration, as well selection, have all left signature on genetic differentiation. Thus, three paradigms postglacial recolonization been described, inferred from patterns DNA Yet some species, especially wide-ranging carnivores, exhibit little structuring between proposed refugia, although relatively few studied due difficulty obtaining samples. Therefore, we investigated mitochondrial variation pine martens, Martes martes, order understand extent which they were affected glacial cycles, compared results with an analysis sequences polecats, Mustela putorius. A general lack ancient lineages, mismatch distribution is consistent expanding population, evidence present-day M. martes Mu. putorius central northern colonized single European refugium following recent glaciation. There has also interspecific introgression sable zibellina Fennoscandia.
