Topic: Vagrant Shrew


  
  Digimorph - Sorex monticolus (Dusky Shrew)
The dusky shrew, Sorex monticolus, is a small to medium sized member of the long-tailed shrew genus Sorex, found within the family Soricidae.
In general, shrews are tiny animals that resemble mice with the addition of a long, pointed snout.
Sorex monticolus is also known as the montane shrew, an appropriate name since it is normally restricted to the mountainous or boreal regions of a corridor stretching from northern Alaska to northern Mexico and extending from the Pacific Ocean east to the Rocky Mountains (Smith and Belk, 1996).

When, on a particular cold night, she happened upon a desert shrew family group (small and cantankerous, but vaguely allied), one male demanded she be taken in and, somehow or another, shrew and anteater ended in an informal marriage.
However, the mother seemed to be dying in childbirth of unknown complications (well, none the shrews could make out) and as soon as the baby was out and squalling, she was devoured and her unfortunate husband died of the sudden heart attacks shrews are so prone to.
Shrews are fast-paced as a rule and it's those rapid-fire, verging-on-emotional-explosion relationships that she's used to.

Shrews include the smallest mammals; the smallest shrews are under 2 in.
A belief that the shrew's bite is poisonous was dismissed for years as a folk tale, but has since been substantiated: the saliva of at least one species of shrew is lethal to mice and can cause considerable pain to humans.
The giant water shrew of Africa is not a true shrew but an insectivore related to the tenrec.

 Moles and Shrews Index
Shrews, the smallest mammals, are also important because they represent the most primitive mammals.
Shrews have a pointed snout, very small eyes, and small ears which typically are hidden in their fur.
Like shrews, their fur is short and almost like velvet which allows them to squeeze through the soil in their burrows in either direction with little resistance.

Shrews are active during the day and night but are rarely seen due to their small size and cryptic behavior.
In a study on population densities of vagrant shrews in western Washington, Newman (1976) calculated densities of 25.8 shrews/ha (10.1/ac) in the fall and winter, and 50.2 shrews/ha (20.32/ac) at the height of summer.
While the shrews found at Kesterson are not Buena Vista Lake shrews, we believe because of the elevated levels of selenium found in portions of the ecosystem, and in some wildlife inhabiting the Tulare Basin, selenium poisoning is a potential threat to the Buena Vista Lake shrew.

 Vagrant Shrew
The vagrant shrew is common to abundant in the Sierra Nevada and Cascades from the Oregon border to northern Inyo Co., and along the coast from the Oregon border to Monterey Bay.
Vagrant shrews can be found in California from sea level to 3750 m (12,000 ft).
In the Sierra Nevada, the vagrant shrew tends to occur at lower elevations than the dusky shrew and to show a weaker relationship to water (Ingles 1961, Spencer and Pettus 1966, Hennings and Hoffmann 1977, but see Hawes 1977).

Dwarf and Vagrant Shrews These 2 shrew species are expected to occur over most of Wyoming, but few observations have been recorded due to the difficulty of trapping shrews and their secretive nature.
Dwarf Shrew (Sorex nanus) (SSC3) Background The dwarf shrew inhabits a variety of habitats from alpine rubble above 4240 m (13,911 ft) in elevation to arid areas in which the predominant vegetation is shortgrass prairie, dry stubble fields or juniper woodlands.
Vagrant Shrew (Sorex vagrans) (SSC3) Background The vagrant shrew occurs in riparian shrub, moist meadow grasslands, bogs, and riparian or marsh habitats with moist soil in a variety of habitats types from sagebrush grassland and mixed shrubland to conifer forest.

The tree shrews are small, squirrel-like mammals native to the tropical forests of South-east Asia.
Although called tree shrews, they are not shrews (although they were previously classified in the Insectivora), and are not all arboreal.
Tree shrews were moved from Insectivora to the Primates order, because of certain internal similarities to the latter, and classified as a primitive prosimian.

Description: The water shrew is a mouse-sized insectivore with a moderately long pointed snout, and a long tail with a distinct keel formed of stiff hairs.
Although water shrews are widespread in mainland Britain, they have a rather localised occurrence, probably because of their preference for clean, clear sources of freshwater for foraging.
Water shrews are mainly found in the northern two-thirds of Wisconsin, north of the tension zone near streams, lakes and wetlands.

Habit: These shrews are active day and night and nests in structures of dry grass and leaves concealed in logs or stumps.
The Vagrant Shrew is sometimes observed using the runways of voles to hunt.
Additional Notes: The Vagrant Shrew does not get its name from having a large home range (which it does not), but from its activity level and the amount of time and energy it spends it hunting.

 Trowbridge's Shrew
Trowbridge's shrews are less tied to water in their distribution, and are more closely associated with the litter layer of mature forests, rather than forest openings and herbaceous layers.
Dalquest (1941) suggested that Trowbridge's shrews are outcompeted by vagrant shrews in wet areas in Washington.
Terry (1981) suggested that Trowbridge's shrews avoid moist areas because of their preference for burrowing and foraging in litter, and suggested that vagrant shrews are outcompeted in drier areas.

It is sometimes called the montane shrew, and once was thought to be the same species as the vagrant shrew.

 ANIMAL WEIGHTS AND THEIR FOOD AND WATER REQUIREMENTS
Smaller animals, like shrews, with higher metabolic rates, and higher surface to volume ratios, have higher water loss and therefore higher consumption rates than larger animals, unless their food has a very high water content.
This shrew consumes 3.3 times its own weight, 13 g, of small invertebrates, young mice and salamanders daily in the summer.

In order of decreasing abundance, the deer mouse, vagrant shrew, Trowbridge’s shrew, and creeping vole were the most abundant and widespread species.
The dusky shrew and the southern red-backed vole were infrequently captured in oak ecotones but were abundant in nearby secondgrowth Douglas-fir forest.
The combination of abundant vagrant shrews and few dusky shrews in oak ecotones suggest that soil food webs and organic matter accumulation differed between oak ecotones and Douglas-fir forest.
