Allozyme variation in bank vole, Myodes glareolus (Mammalia: Rodentia) in Northern Anatolia

Abstract 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 , α-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.
