[Genetic Structure of the Common Shrew Sorex araneus L. 1758 (Mammalia, Lipotyphla) in Continuous and Fragmented Areas].

In this work the genetic variability of the common shrew populations Sorex araneus L. in Eastern Europe was studied via sequencing of the mitochondrial gene cyt b. A total of 82 sequences of the mitochondrial gene cyt b with a length of 953 basepairs were analyzed, including five chromosome races in a continuous area of the species in forest zone and two races in fragmented area in the steppe zone.
