Systematics of Short-Tailed Shrews (Genus Blarina) in Texas

Abstract
Geographic variation among populations of short-tailed shrews (genus Blarina) from Texas is reviewed herein using univariate and multivariate statistics. In terms of size, two phena (which are arranged into three subspecies) of short-tailed shrews occur in Texas. The smallest shrews (B. carolinensis minima) occur in the southern part of eastern Texas; the largest shrews are from the northern and central parts of eastern Texas (B. c. carolinensis) and from Aransas County in southern Texas (B. c. plumbea). The size relationships of the three subspecies are interpreted in light of the morphology and geographic distribution of Blarina in Texas during the Pleistocene.
