Animalia Chordata Mammalia Rodentia Sciuridae

Scientific Name: Marmota broweri
Species Authority: Hall & Gilmore, 1934
Common Name(s):
English Alaska Marmot
Taxonomic Notes: Marmota broweri was regarded as a synonym or subspecies of M. caligata, the hoary marmot of western North America, in the past, but Jones et al. (1992) and Hoffman et al. (in Wilson and Reeder 1993) and Thorington and Hoffmann (in Wilson and Reeder 2005) recognized M. broweri and M. caligata as distinct species.
