Blarina hylophaga (Sorciomorpha: Soricidae)

چکیده
Blarina hylophaga (Elliot, 1899) is a soricid commonly called Elliot’s short-tailed shrew. A short-legged, robust shrew with a long, pointed snout and a short tail; it is 1 of 4 species in the genus Blarina. It occurs throughout most of the Great Plains of the United States, where it inhabits moist, well-drained grassland and riparian areas with deep leaf litter. It is listed as a species of greatest conservation need in Iowa and at possible risk in Texas, which might be due to the limited knowledge of the species throughout its geographic range.

Distribution and Taxonomic Status of Blarina hylophaga Elliot (Insectivora: Soricidae)
Systematic relationships of southern populations of short-tailed shrews (genus Blarina) are assessed on the basis of univariate and multivariate statistics. Populations are separated into two phena; southwestern short-tailed shrews are significantly larger morphometrically than southeastern forms. The two phena apparently represent distinct species. The name Blarina hylophaga is available for s...
متن کاملSystematics of Isolated Populations of Short-tailed Shrews (soricidae: Blarina) in Texas
Two isolated and taxonomically unassigned populations of short-tailed shrews (Blarina) exist in Texas, 1 in the Lost Pines region including Bastrop County and 1 at Aransas National Wildlife Refuge on the Gulf Coast. Molecular and morphological methods were used to determine the systematic status of the 2 disjunct Texas populations. Multivariate analyses of size-influenced cranial measurements w...
متن کاملIdentification and characterization of the contact zone between short-tailed shrews (Blarina) in Iowa and Missouri
Short-tailed shrews (genus Blarina Gray, 1838) are characterized by divergent karyotypes and are genetically distinct. Blarina species are similar morphologically but, in most cases, can be distinguished morphometrically. Blarina distributions tend to be parapatric along well-defined contact zones; however, it has been suggested that the northern short-tailed shrew (Blarina brevicauda (Say, 182...
متن کاملAllozyme differentiation in five species of North American shrews (Soricidae: Mammalia)
Starch gel electrophoresis was used to investigate patterns of genetic variation in five species of shrews from southern Illinois, and western Kentucky and Tennessee. Four of the five species occur sympatrically. Twenty-eight presumptive loci were examined in the following species: pygmy shrew Sorex hoyi Baird, southeastern shrew Sorex longirostris, northern short-tailed shrew Blarina brevicaud...
