Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA EULIPOTYPHLA SORICIDAE

Scientific Name: Neomys teres
Species Authority: Miller, 1908
Common Name(s):
English Transcaucasian Water Shrew
Synonym(s):
Neomys schelkovnikovi Satunin, 1913

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Kryštufek, B. & Bukhnikashvili, A.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Temple, H. (Global Mammal Assessment Team)
Justification:
The species is Least Concern because it is relatively widespread, can be common in suitable habitat, and although there are localized threats, this species is not declining at a rapid enough rate to qualify for a threatened category. However, the water shrew is declining in Georgia, and populations should be monitored.

Population [top]

Population: Common, in some areas abundant species in western part of the range. The species is generally declining in Georgia (GMA SW Asia Workshop 2005). In Turkey, there are few problems - the species varies in abundance by season and potentially year.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Inhabits riverbanks, prefers small rivers and brooks. Swims and dives very well. Makes nests in abandoned rodent burrows, between roots, or in brushwood; sometimes digs its own burrow. Solitary. Feeds on aquatic (invertebrates, molluscs, fish roe and fingerlings, tadpoles, froglings) and terrestrial (beetles, earthworms, sometimes young rodents) animals. The saliva of this species is poisonous; the water shrew paralyzes prey with its bite, and may store living (but immobilized) prey in its burrows. Prey storing is especially important during winter. The water shrew reproduces up to 3 times a year, with 5-9 young in each litter. Some females start reproducing during their first year. Longevity in nature is about 2 years, in captivity up to 4 years.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Overgrazing may have a negative impact on some populations. The species may also be locally disturbed by tree removal and erosion. These are not considered major threats at present.

Conservation Actions [top]

Conservation Actions: Found in protected areas. Due to its habitat specialization and relatively unknown biology, the species should be monitored.
