The European snow vole or snow vole Chionomys nivalispreviously Arvicola nivalis and Microtus nivalis is a species of rodent in the family Cricetidae. The European snow vole is native to mountainous parts of southern and eastern Europe and southwestern Asia. Its habitat is rocky areas and screesmostly above the chionommys line. It is mainly a solitary animal and lives under boulders and in crevices and tunnels among rocks and scree. The European snow vole was first described by Martins in as Arvicola nivalis.
Gromov and Polyakov erected the genus Chionomys in and the name Chionomys nivalis is now accepted, although the exact affinities of the species are not fully established. All three species are present in the Caucasus and the Pontic Mountains in northeastern Turkey. The European snow vole has soft, long, dense fur that is pale grey tinged with brown. It nuvalis a rounded nose, black beady eyes, long whitish cuionomys and moderately large ears.
The comparatively long tail is whitish and clad in short, sparse hairs.
The head and body length is 4. Its voice is a squeak and its teeth can sometimes be heard chattering. Its presence in any location is due to the suitability of the microhabitat rather than the suitability of the temperature. However it is more often found at medium to high altitudes because there is less competition from other animals such as grasshoppersthe alpine marmot Marmota marmotathe ibex Capru spp.
When suitable petricolic soils occur in forests it is less likely to be plentiful because it faces competition from such mammals as the edible dormouse Glis glis and the garden dormouse Eliomys quercinus.
A study of the European snow vole concluded that it was a rock-dwelling specialist. The researchers showed that reproductive females and juveniles preferentially used the central parts of scree areas, especially in the vicinity of scree junipers Juniperus communiswhereas males and non-reproductive females were less discriminating and occupied rocky habitat in proportion to its availability. In the summer breeding season, female European snow voles have mutually exclusive territories and display considerable aggression towards other females of their own species when they meet near the territorial boundaries.
Males have rather larger, overlapping ranges, and are more socially tolerant. In the winter the territorial boundaries break down and individual males and females become nomadic and solitary. They are aggressive towards other members of their species that they may encounter. When a female meets another female they will often fight but when a male encounters another male, more investigative behaviour takes place.
However, if they do fight, it will be a more intense battle. Males encountering females show intermediate behaviours. These behaviours are probably related to the competition necessary to find chionomts food in the snow voles’ challenging environment, and is in contrast to some other vole species living in more temperate climates. Some of these live solitary lives during the summer and form communal groups in the winter. This vole is active by night as well as by day and in the summer it is quite easy to spot lying on rocks, especially on sunny days.
It digs tunnels with numerous exit holes among rocks and between tree roots. It does not hibernate in wintertime and may take shelter in mountain huts. Chionoms holds its tail in an upright position when running. It feeds on the green parts of plants, grasses, buds, shoots and roots, and may sometimes eat insects and their larvae. In the summer it gathers bits of grass and leaves, leaving them to dry in the sun before storing them in underground chambers for winter use as food.

The European snow vole is promiscuous in its mating habits with both males and females mating with multiple partners. There are usually two litters in a year, with litters of about four range two to seven young being born after a gestation period of three weeks. The young are altricialtheir eyes open after about thirteen days, they are weaned at eighteen days and become independent chionojys four weeks. They do not generally breed until the following year and may live for two to four years.
This is because, despite its rather fragmented range, it is common in some suitable habitats, its population trend seems stable and it does chinoomys seem to be facing any particular threats.
