Factors affecting distribution and habitat selection of water shrews Neomys fodiens
… and associated habitat preferences of water shrews, a species of conservation concern, by comparing populations in central England freshwater habitats. Bait tube surveys were undertaken at 32 freshwater sites to establish water shrew presence, half of which were found to contain water shrews. …

The phylogeography of the short-tailed shrews (genus Blarina) of southeast Tennessee
… is key to deciphering their biogeography. Shrews of the genus Blarina are some of the most common and abundant mammals in this region. Two species are found in southeast Tennessee: Blarina brevicauda and Blarina carolinensis. To clarify their geographic ranges, Blarina vouchers were …

Ecological and Genetic Connectivity of Shrews (Sorex spp.) across Interstate-90 in the Washington Cascade Range
… project. The goal of my study was to investigate shrews – very small mammals with presumably low mobility and dispersal capacity – at sites on the eastern slopes of the Cascade Range where wildlife crossing structures will be built in the future. My main objectives were to verify shrew species …

MOLECULAR AND MORPHOLOGICAL CONSEQUENCES OF POST-GLACIAL CONTACT AMONG LINEAGES OF NORTHERN SHORT-TAILED SHREWS (Blarina brevicauda) IN EASTERN NORTH AMERICA
… are less well-documented. Northern short-tailed shrews (<em>Blarina brevicauda</em>) are restricted to eastern North America, yet they exhibit three different mitochondrial lineages that diverged when historical populations retracted and became isolated from one another. In this study, I …

The Ultrastructure of the Olfactory System in Two Species of Short-Tailed Shrews, <i>Blarina brevicauda</i> and <i>Blarina carolinensis</i>
… examined by light and electron microscopy. These shrews were live trapped in the vicinity of Norfolk, Virginia throughout all months of the year. Olfactory tissues were processed following standard transmission and scanning electron microscopy protocols. The olfactory system structures …

Small mammal communities on a reclaimed mountaintop mine/valley fill landscape in southern West Virginia
… (Microtus pinetorum), northern short-tailed shrews (Blarina brevicauda), and pygmy shrews (Sorex hoyi) were more common in forest treatments; Peromyscus, house mice (Mus musculus), southern bog lemmings ( Synaptomys cooperi), and masked shrews (S. cinereus) were more common in reclaimed …

Morphometric and genetic variation among populations of the southern short-tailed shrew, Blarina carolinensis, located along the Coastal Plain of Virginia
<p>The distribution of short-tailed shrews, Blarina carolinensis and B. brevicauda, demonstrates contiguous allopatry in peninsular situations in the Coastal Plain of Virginia, and in other areas. The distribution of these two species is unusual in that they do not exhibit syntopy except within a …

Small Mammals in Prairie Wetlands: Habitat Use and the Effects of Wetland Modifications
… followed by deer mice (Peromyscus spp.), masked shrews (Sorex cinereous), meadow jumping mice (Zapus hudsonius) and northern short-tailed shrews (Blarina brevicauda). Deer mine were more common in modified habitats within wetland basins than in undisturbed habitat. Modification of wetlands tended …

Habitat Associations and Demography of Small Mammals in 4 Forest Cover Types on Quantico Marine Corps Base, Virginia
… (Peromyscus leucopus), northern short-tailed shrews (Blarina brevicauda), eastern chipmunks (Tamias striatus), meadow voles (Microtus pennsylvanicus), and woodland voles (Microtus pinetorum), accounted for approximately 95% of the total number of individuals captured. Overall relative …

Influence of Vegetation On The Distribution of Small Mammals On A Waterfowl Production Area
… Jumping ice (Zapus hudsonius), masked shrews (Sorex cinerius), short tailed shrews (Blarins brevicauda), grasshopper mice (Omychomys leucogaster) and house mice (Mis musculus) were also taken. The bluegrass association had the highest number of small mammal captures and the reseeded …

Environmental Factors Affecting the Landscape-Scale Spatio-Temporal Distribution of Small Mammal Assemblages Across the Northern Great Plains of North America
… the spatiotemporal distributions of rodents and shrews (small mammals), particularly in heterogeneous landscapes. I used owl pellets as an alternative sampling method, from which the remains of 60,972 individuals were identified and quantified in samples collected across 4.3 million hectares over …

Effects of low level lead and cadmium on reproduction in Peromyscus leucopus and a study of lead concentration in small mammals from old orchards
… of contamination has been removed. Short-tailed shrews (Blarina brevicauda) trapped in an orchard with a history of lead arsenate use had higher whole body lead concentrations than individuals of the same species trapped in a control orchard. Within the treated orchard lead concentrations in pine …

The effects of a silvicultural sludge application on small mammal populations and the potential of Giardia contamination in a forest ecosystem
… Townsend chipmunk (Eutamias townsendii), shrews (Sorex spp.), and a few species caught occasionally, were sampled in control and treatment study sites from May 1990 to October 1991. Sludge application occurred in November 1990. There were no detectable differences in the abundances of deer …
