Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA RODENTIA CRICETIDAE

Scientific Name: Arvicola scherman
Species Authority: (Shaw, 1801)
Taxonomic Notes: Linnaeus' amphibius and terrestris, both proposed in 1758 on the same page, are now considered conspecific by most researchers. As shown by Corbet (1978), amphibius has a priority over terrestris, based on Blasius (1857) as the first reviser. Recently, this species was split into A. amphibius and A. scherman (Panteleyev 2001, Wilson and Reeder 2005). Arvicola amphibius is larger, with shaggy pelage and ortodont incisors, and is associated with aquatic environment; A. scherman is smaller, with softer pelage, more reduced plantar and palmar tubercles, and the upper incisors strongly projecting forwards and has fossorial habits (Panteleyev 2001). Mitochondrial phylogeny based on sequences of 800 to 1,200 BP of the mitochondrial cytochrome b gene suggests taxonomy of A. amphibius group to be more complex: three main groups were distinguished within A. amphibius: (1) strictly fossorial water voles from the mountain regions of Europe, (2) aquatic and transitional populations living south of the Alps, and (3) a heterogeneous group of the remaining aquatic populations (Wust Saucy 1998).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Amori, G., Hutterer, R., Kryštufek, B., Yigit, N., Mitsain, G. & Muñoz, L.J.P
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Temple, H. (Global Mammal Assessment Team)
Justification:
Arvicola scherman has a wide distribution, and is considered a pest in parts of the range. Not under serious threat at present and therefore Least Concern.

Geographic Range [top]

Range Description: There is much confusion between A. amphibius and A. scherman and the distribution of both taxa should be considered tentative. A. scherman occurs mainly in mountainous areas in southern and central Europe (Saucy 1999, Panteleyev 2001, Wilson and Reeder 2005). In the French Alps it occurs to 2,400 m (Reichstein 1982).

Population [top]

Population: Pronounced cyclic population fluctuations occur every 5-8 years, with densities ranging between 0 and 1,000 individuals per hectare (Saucy 1999). At high densities it becomes an agricultural pest. A main pest in orchards (e.g., in Slovenia (B. Krystufek pers comm. 2007).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: Mainly restricted to the uplands, where constructs extensive underground burrows in grasslands (including pastures) or, less frequently, in woodlands. Predominantly herbivorous, feeding on vegetation in the summer and on roots, bulbs and tubers in the winter (Saucy 1999). The species lives in complex burrows that are usually not deeper than 1 m.
Systems: Terrestrial

Threats [top]

Major Threat(s): No threats known.

Conservation Actions: Occurs in some protected areas. No specific measures in place.
