Tamiasciurus Hudsonicus CT
Pine squirrels are squirrels of the genus ''Tamiasciurus'', in the Sciurini tribe, of the large family Sciuridae. Species This genus includes three species: *''Tamiasciurus douglasii'' — Douglas squirrel **''T. d. mearnsi'' — Mearns's squirrel *''Tamiasciurus fremonti'' — southwestern red squirrel **''T. f. grahamensis'' — Mount Graham red squirrel *''Tamiasciurus hudsonicus'' — American red squirrel All three species are native to North America.

Description Pine squirrels, ''Tamiasciurus'' species, are small tree squirrels with bushy tails. Along with members of the genus ''Sciurus'', they are members of the Sciurini tribe. The name ''Tamiasciurus'' comes from Greek wiktionary:ταμίας ''tamías'' ‘steward, dispenser’ and wiktionary:σκίουρος ''skíouros'' 'squirrel'.

Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Mount Graham Red Squirrel
The Mount Graham red squirrel (''Tamiasciurus fremonti grahamensis'') is an endangered subspecies of the southwestern red squirrel (''Tamiasciurus fremonti'') native to the Pinaleño Mountains of Arizona. It is smaller than most other subspecies of red squirrel, and also does not have the white-fringed tail that is common to the species. Its diet consists mainly of mixed seeds, conifer cones and air-dried fungi. It exhibits similar behavior to other squirrels in its species. Description Physical The Mount Graham red squirrel is a generally tiny squirrel weighing on average around and measuring about in length. The subspecies also has a tail. Unlike most other squirrels in its species, the squirrels do not have a white-fringed tail. Both females and males share similar markings and features and are typically grayish brown in color with rusty yellow or orange markings on their backside. During the winter season, the squirrels' ears are tufted with fur, and during the summer a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rodents Of Canada
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia ( ), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/ricochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Once included with rodents, rabbits, hares, and pikas, w ...

Red Squirrel
The red squirrel (''Sciurus vulgaris''), also called Eurasian red squirrel, is a species of tree squirrel in the genus ''Sciurus''. It is an arboreal and primarily herbivorous rodent and common throughout Eurasia. Taxonomy There have been over 40 described subspecies of the red squirrel, but the taxonomic status of some of these is uncertain. A study published in 1971 recognises 16 subspecies and has served as a basis for subsequent taxonomic work. Although the validity of some subspecies is labelled with uncertainty because of the large variation in red squirrels even within a single region, others are relatively distinctive and one of these, ''S. v. meridionalis'' of South Italy, was elevated to species status as the Calabrian black squirrel in 2017. At present, there are 23 recognized subspecies of the red squirrel. Genetic studies indicate that another, ''S. v. hoffmanni'' of Sierra Espuña in southeast Spain (below included in ''S. v. alpinus''), deserves recognition a ...

Sciurus
The genus ''Sciurus'' ( or ) contains most of the common, bushy-tailed squirrels in North America, Europe, Temperate zone, temperate Asia, Central America and South America. Species The number of species in the genus is subject to change. In 2005, Thorington & Hoffman- whose taxonomic interpretation is followed by the IUCN website- accepted 28 species in the genus: Genus ''Sciurus'' *Subgenus ''Sciurus'' **Allen's squirrel, ''Sciurus alleni'' **Arizona gray squirrel, ''Sciurus arizonensis'' **Mexican gray squirrel, ''Sciurus aureogaster'' **Eastern gray squirrel, ''Sciurus carolinensis'' **Collie's squirrel, ''Sciurus colliaei'' **Deppe's squirrel, ''Sciurus deppei'' **Japanese squirrel, ''Sciurus lis'' **Calabrian black squirrel, ''Sciurus meridionalis'' **Mexican fox squirrel, ''Sciurus nayaritensis'' **Fox squirrel, ''Sciurus niger'' **Peters's squirrel, ''Sciurus oculatus'' **Variegated squirrel, ''Sciurus variegatoides'' **Red squirrel, Eurasian red squirrel, ''Sciurus vul ...

Tree Squirrel
Tree squirrels are the members of the squirrel Family (biology), family (Sciuridae) commonly just referred to as "squirrels". They include more than 100 arboreal species native to all continents except Antarctica and Oceania. They do not form a single natural, or monophyly, monophyletic, group; they are variously related to others in the squirrel family, including ground squirrels, flying squirrels, marmots, and chipmunks. The defining characteristic used to determine which species of Sciuridae are tree squirrels is dependent on their habitat rather than their physiology. Tree squirrels live mostly among trees, as opposed to those that live in burrows in the ground or among rocks. An exception is the flying squirrel that also makes its home in trees, but has a physiological distinction separating it from its tree squirrel cousins: special flaps of skin called patagia, acting as glider wings, which allow gliding flight. The best-known genus of tree squirrels is ''Sciurus'', which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
