American red squirrel

Poxvirus infection in an American red squirrel (Tamiasciurus hudsonicus) from northwestern Canada.

The North American red squirrel (Tamiasciurus hudsonicus) is a small (<250 g) tree squirrel found in conifer forests throughout northern North America and the Rocky Mountains of the western United States (Steele, 1998).

Recently, Jung and Slough (2012) reported an isabelline-colored American Red Squirrel (Tamiasciurus hudsonicus), and we are aware of 2 mammalian taxa that are named after their "washed out" coloration: the pale-colored Meridional Serotine Bat (Eptesicus isabellinus) found near the Strait of Gibraltar, and a sandy-colored subspecies of Brown Bear (Ursus arctos isabellinus) found in central Asia.

Michigan State University, is studying how North American red squirrel (Tamiasciurus hudsonicus) mothers are adaptively modifying offspring phenotype via hormone-mediated maternal effects;

We used telemetry, direct observation, and long-term mark-recapture (9 yr) to study breeding dispersal in the North American red squirrel (Tamiasciurus hudsonicus) at Kluane, Yukon, Canada.

Mean size of home ranges for Mount Graham red squirrels exceed 3.0 ha in unburned forest, surpassing the largest home ranges reported for North American red squirrels (Froehlich and Smith, 1990; Kreighbaum and Van Pelt, 1996; Koprowski et al., 2008; Zugmeyer and Koprowski, 2009).
