Abstract :
[en] The exact location of glacial refugia and the patterns of postglacial range expansion of European mammals are not yet completely elucidated. Therefore, further detailed studies covering a large part of the Western Palearctic region are still needed. In this order, we sequenced 972 bp of the mitochondrial DNA cytochrome b (mtDNA cyt b) from 124 yellow-necked fieldmice (Apodemus flavicollis) collected from 53 European localities. The aims of the study were to answer the following questions: Did the Mediterranean peninsulas act as the main refuge for yellow-necked fieldmouse or did the species also survive in more easterly refugia (the Caucasus or the southern Ural) and in Central Europe? What is the role of Turkey and Near East regions as Quaternary glacial refuges for this species and as a source for postglacial recolonisers of the Western Palearctic region? The results provide a clear picture of the impact of the quaternary glaciations on the genetic and geographic structure of the fieldmouse. This species survived the ice ages in two main refuges, the first one in the Italo-Balkan region; the second one in Turkey and the Near East regions. It is from the Balkan refuge that it recolonised all European regions at the end of the last glaciation. The Turkish and Near East populations are distinct from the European ones and they did not recolonise the Palearctic region probably because: (i) they were blocked by the Black Sea and the Caucasus, (ii) the long term presence of fieldmice populations in the Balkans prevented their expansion. These are genetically differentiated from the European and Russian ones and could be described as a particular subspecies. This result emphasises the importance of Turkey and the Near and Middle East regions as a refuge for Palearctic mammals.
