Tamias Urialis
''Tamias'' is a genus of chipmunks in the tribe Marmotini of the squirrel family. The genus includes a single living species, the eastern chipmunk (''Tamias striatus''). The genus name ''Tamias'' ( el, ταμίας) means "treasurer", "steward", or "housekeeper", which is a reference to the animals' role in plant dispersal through their habit of collecting and storing food for winter use. The genus ''Tamias'' was formerly divided into three subgenera that, in sum, included all chipmunk species: ''Tamias'', the eastern chipmunk and other fossil species; ''Eutamias'', of which the Siberian chipmunk (''E. sibiricus'') is the only living member; and '' Neotamias'', which includes the 23 remaining, mostly western, species. These classifications are subjective, and most taxonomies over the twentieth century have placed the chipmunks in a single genus. However, studies of mitochondrial DNA show that the divergence between each of the three chipmunk groups is comparable to the genet ...

Eastern Chipmunk
The eastern chipmunk (''Tamias striatus'') is a chipmunk species found in eastern North America. It is the only living member of the chipmunk genus ''Tamias''. Etymology The name "chipmunk" comes from the Ojibwe word ''ajidamoo'' (or possibly ''ajidamoonh'', the same word in the Ottawa dialect of Ojibwe), which translates literally as "one who descends trees headlong." First described by Mark Catesby in his 1743 ''The Natural History of Carolina, Florida, and the Bahama Islands'', the chipmunk was eventually classified as ''Sciurus striatus'' by Linnaeus, meaning "striped squirrel" in Latin. The scientific name was changed to ''Tamias striatus'', meaning "striped steward," by Johann Illiger in 1811. Description A small species, it reaches about in length including the tail, and a weight of . It has reddish-brown fur on its upper body and five dark brown stripes contrasting with light brown stripes along its back, ending in a dark tail. It has lighter fur on the lower part ...

Spermophilus
''Spermophilus'' is a genus of ground squirrels in the Sciuridae, squirrel family. As traditionally defined the genus was very species-rich, ranging through Europe, Asia and North America, but this arrangement was found to be paraphyletic to the certainly distinct prairie dogs, marmots, and antelope squirrels. As a consequence, all the former ''Spermophilus'' species of North America have been moved to other genera, leaving the European and Asian species as true ''Spermophilus'' (the only exceptions are two Asian ''Urocitellus''). Some species are sometimes called susliks (or sousliks). This name comes from Russian :ru:Суслики, суслик, ''suslik''. In some languages, a derivative of the name is in common usage, for example ''suseł'' in Polish. The scientific name of this genus means "seed-lovers" (gr. σπέρμα ''sperma'', genitive σπέρματος ''spermatos'' – seed; φίλος ''philos'' – friend, lover).

Rodent Genera
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 New Zealand, 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/richochetal (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. Rabbits, hares, and pikas, whose incisors ...

Tamias
''Tamias'' is a genus of chipmunks in the tribe Marmotini of the squirrel family. The genus includes a single living species, the eastern chipmunk (''Tamias striatus''). The genus name ''Tamias'' ( el, ταμίας) means "treasurer", "steward", or "housekeeper", which is a reference to the animals' role in plant dispersal through their habit of collecting and storing food for winter use. The genus ''Tamias'' was formerly divided into three subgenera that, in sum, included all chipmunk species: ''Tamias'', the eastern chipmunk and other fossil species; ''Eutamias'', of which the Siberian chipmunk (''E. sibiricus'') is the only living member; and ''Neotamias'', which includes the 23 remaining, mostly western, species. These classifications are subjective, and most taxonomies over the twentieth century have placed the chipmunks in a single genus. However, studies of mitochondrial DNA show that the divergence between each of the three chipmunk groups is comparable to the genetic di ...

Tamias Aristus
''Tamias aristus'' is an extinct species of chipmunk that lived during the late Pleistocene epoch. It was characterized from a fossilized skull found in a limestone quarry in Ladds, Bartow County, Georgia. The name is derived from the Greek aristos, meaning noblest. The fossil closely resembles the skull of ''Tamias striatus'', but all dimensions of the ''T. aristus'' skull are consistently 10-30% larger than the largest examples of ''T. striatus''. While it is suspected the two species are closely related, their relationship is unclear as ''T. striatus'' fossils have been found in the same Faunal assemblage, fossil assemblage and poor Stratigraphy, stratigraphic control in the area makes temporal relationships hard to identify.

Eurasia
Eurasia (, ) is the largest continental area on Earth, comprising all of Europe and Asia. Primarily in the Northern and Eastern Hemispheres, it spans from the British Isles and the Iberian Peninsula in the west to the Japanese archipelago and the Russian Far East to the east. The continental landmass is bordered by the Atlantic Ocean and Africa to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two continents is a historical social construct, as many of their borders are over land; thus, in some parts of the world, Eurasia is recognized as the largest of the six, five, or four continents on Earth. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on paleomagnetic data. Eurasia covers around , or around 36.2% of the Earth's total land area. It is also home to the largest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
