Search for: [Description = "Analysis of dental characters of Chionomys supported by a comparison with biochemical and karyological criteria shows its isolation from Microtus \(sensu stricto\). Snow voles \(Chionomys\) consist of two lineages developed separately since the Lower Biharian. The first one has appeared and evolved in Europe \(Ch. nivalis lineage\) while the second is probably of the Near East or Caucasus origin \(Ch. roberti\-gud lineage\). Variation in dental characters of extant Ch. nivalis permit to reconstruct affinities between particular populations comparable in this respect with biochemical data. Fossil species traditionally included in the Chinomys group \(Microtus malei, M. nivaloides, M. nivalinus, M. ratticepoides\) seem to belong to Microtus sensu stricto."]
