The currently accepted scientific name for Abert's squirrel is Sciurus aberti Woodhouse, 1853. [4] Woodhouse had initially described the species as Sciurus dorsalis in 1852, but this name turned out to be preoccupied by Sciurus dorsalis Gray, 1849 (now a subspecies of variegated squirrel S. variegatoides), and thus the present species was renamed.
Additionally, the paper suggests moving Andean squirrel back to subtribe Microsciurina, the dwarf squirrels, and assigns it to the newly described genus Leptosciurus. The paper's findings agree with prior assessments to synonymize Richmond's squirrel into Red-tailed squirrel and reassigns the Red-tailed squirrel into the previously monotypic ...
The Kaibab squirrel is an example of evolution occurring through geographic isolation, but not because of the canyon. [2] Compared to the Kaibab squirrel, the Abert's squirrel, with its several subspecies, has a much broader distribution and is found on the South Rim of the Grand Canyon. The difference between North Rim and South Rim Abert's ...
Sciurini (/ s ɪ ˈ j uː r ɪ n iː /) is a tribe that includes about forty species of squirrels, [2] mostly from the Americas. It includes five living genera—the American dwarf squirrels, Microsciurus; the Bornean Rheithrosciurus; the widespread American and Eurasian tree squirrels of the genus Sciurus, which includes some of the best known squirrel species; the Central American ...

The Arizona gray squirrel has had no recent expansion or reduction in the size of their range in New Mexico, though there has been some population decline. This is due to habitat loss and the introduction of Abert’s squirrel, which has in some cases outcompeted the Arizona gray squirrel for resources. [6]
As its name suggests, its fur is predominantly reddish brown, but there is a naturally occurring gray morph known as the "silver" fox. The red fox is by far the most widespread and abundant species of fox , found in almost every single habitat in the Northern Hemisphere, from the coastal marshes of United States, to the alpine tundras of ...
Squirrels are generally small animals, ranging in size from the African pygmy squirrel and least pygmy squirrel at 10–14 cm (3.9–5.5 in) in total length and just 12–26 g (0.42–0.92 oz) in weight, [8] [9] to the Bhutan giant flying squirrel at up to 1.27 m (4 ft 2 in) in total length, [10] and several marmot species, which can weigh 8 kg ...
