  • Snow voles, genus Chionomys, of Turkey
    Kryštufek, Boris, 1954-
    Three species of snow vole are known from Turkey. The true snow vole, Chionomys nivalis, has been recorded from 20 localities and is widespread in Anatolia. However, Robert's vole, C. roberti, and ... the Gudaur vole, C. gud, are restricted to the eastern Pontic Mts. where they are known from 11 and 4 localities, respectively. It is suggested that snow vole distributions were shaped by the degree to which individual species are associated with rocky environments (nivalis = gud > roberti) and by their dependence on mesic conditions (roberti > gud > nivalis). Robert's vole is the most distinct in both morphology and habitat selection. The snow vole and Gudaur vole are sympatric at three localities, although the former populates dryer habitats. These species are well differentiated morphologically, the snow vole having a deeper skull and larger bullae ; when in sympatry, the tail of the Gudar vole is longer. No interpopulation variation was observed in external and cranial characters in Robert's and Gudaur voles. On the other hand, the true snow vole is highly variable, although the pattern of geographic variation found in dental characters does not correspond with that derived from cranial data.
