    Allozyme variation in bank vole, Myodes glareolus (Mammalia: Rodentia) in Northern Anatolia
    (PERGAMON-ELSEVIER SCIENCE LTD, 2013) Colak, Reyhan; Kandemir, Irfan; Karacan, Gul Olgun; Kankilic, Teoman; Colak, Ercument; Yigit, Nuri; Ozkurt, Sakir Onder
    A total of 94 specimens from 16 populations of Myodes glareolus, collected between 2004 and 2007, from different altitudinal distributions were analyzed, using 16 enzyme systems. We found that 10 out of 22 loci (Idh-2, alpha-Gpdh, Me, Pgm, Pgd, Mdh-s, Ada, Est-1, Ldh-1, and Ldh-2) were polymorphic. Group 1 included population from altitudes ranging from 27 to 605 m above sea level (ASL), and Group 2 were from altitudes ranging from 1003 to 1288 m ASL. The summaries of the genetic parameters also displayed differences between the 2 groups. The possible reasons of such fragmentation between M. glareolus populations were discussed.

    Genetic variations of Turkish bank vole, Myodes glareolus (Mammalia: Rodentia) inferred from mtDNA
    (TAYLOR & FRANCIS LTD, 2016) Colak, Reyhan; Karacan, Gul Olgun; Kandemir, Irfan; Colak, Ercument; Kankilic, Teoman; Yigit, Nuri; Michaux, Johan
    The bank vole, Myodes glareolus, lives in deciduous forests throughout the Palearctic region. In Turkey, this species is distributed only in northern Anatolia (the Black Sea region) where these forests exist. This study reveals genetic differentiation among bank vole populations based on two regions of mitochondrial DNA (cytochrome b and D-loop). Populations in northern Anatolia are divided into two genetic lineages (the "eastern" and "western Black Sea" lineages) by the Kizilirmak Valley. While the western Black Sea lineage is close to the Balkan lineage, in accordance with their geographical proximities, surprisingly, the Uludag lineage, also situated in Western Turkey appears related to the eastern Black Sea population. The divergence time analyses suggest a separation between the Balkan and Turkish groups around 0.26 Mya, whereas the split between the eastern and western Black sea lineages appeared a little bit later (0.20 Mya). Our results suggest that regional refuges existed for this species in Turkey and that small-scale habitat fragmentations led to genetic differentiations between Myodes populations.
