Olympic Shrew
French: Musaraigne de Rohwer / German: RohwerSpitzmaus / Spanish: Musarana de Olympic
Other common names: Rohwer's Shrew
Taxonomy. Sorex rohwer: R. L.. Rausch, Feagin & V. R. Rausch, 2007 ,
“ Olympic Peninsula , Washington State , near Quilcene , Penny Creek , at lat. 47°51’ N, long. 122°57W.” GoogleMaps
Sorex rohweri was only recently described as a distinct species from S. cinereus (which it was originally misidentified as) and is in the S. cinereus group and subgenus Ofisorex. S. rohweri seems to represent a basal lineage in the S. cinereus group (¢.870.000 years ago) and probably diverged early in the evolutionary history of the group. Monotypic.
Distribution. SW Canada (SW British Columbia) and NW USA (W Washington and NW Oregon). View Figure
Descriptive notes. Head-body 47-69 mm, tail 37-49 mm, hindfoot 10-13 mm. No specific data are available for body weight. The Olympic Shrew is small to mediumsized and externally similar to the Masked Shrew ( S. cinereus ). Dorsum is dark brown, and venter is slightly lighter. Tail averages 78% (63-100%) of head-body length and is uniformly dark brown. Teeth are pigmented dark red and are typically paler than in the Masked Shrew and Vagrant Shrew ( S. vagrans ). Upper incisors of the Olympic Shrew have wider interdenticular space (being more V-shaped) than in the Masked Shrew. There are five unicuspids, gradually getting slightly smaller from first to fourth, with fifth being minute compared with the other four.
Habitat. Primarily lowland mature stands in temperate moist forests from sea level up to elevations of ¢.700 m. Olympic Shrews are also occasionally found in areas in which forests have been cleared or degraded.
Food and Feeding. No information.
Breeding. No information.
Activity patterns. No information.
Movements, Home range and Social organization. No information.
Status and Conservation. Classified as Least Concern on The IUCN Red List. The Olympic Shrew has a relatively wide distribution and can be found in disturbed habitats, indicating that it is tolerant of human activity. Very little is known of its ecology.
