Following the SINEs: A Taxonomic Revision of the Long-Tailed Shrew Complex, Sorex dispar and S. gaspensis
Taxonomists have debated whether the complex of long-tailed shrews adapted to talus slope formations in the Appalachian Mountain range in eastern North America should be considered 1 species ( Sorex dispar ) or 2 species ( S. dispar and S. gaspensis ). Recent analyses of mitochondrial DNA and morpho...

Taxonomists have debated whether the complex of long-tailed shrews adapted to talus slope formations in the Appalachian Mountain range in eastern North America should be considered 1 species ( Sorex dispar ) or 2 species ( S. dispar and S. gaspensis ). Recent analyses of mitochondrial DNA and morphological data have suggested that these 2 taxa should be considered conspecifics. To help resolve this debate, a combination of mitochondrial (cytochrome- b [ Cytb ] sequence data) and nuclear markers (inter–SINE fingerprinting [where SINE is short interspersed element]) markers was analyzed from specimens collected from across the range of this complex, including the zone of contact between these putative species.
