title: The snow vole (Chionomys nivalis) as an appropriate environmental bioindicator in alpine ecosystems.
abstract: The snow vole (Chionomys nivalis, Martins, 1842) is a common species in the Bulgarian high mountains. Its populations are distributed in different altitudes, regions, and keep stable population density. This is the reason the species has been tested as a bioindicator for environmental quality in alpine ecosystems. The cumulative environmental impact in snow vole populations was evaluated using cytogenetical, hematological, ecotoxicological, radiometrical, ecophysiological, and morphophysiological indices. Standard karyotype, chromosomal aberrations, and other diversions have been observed. These investigations reveal that the snow vole is one of the most appropriate species that can be used as a biomonitor for environmental assessment in mountain areas.
