Yukon Deer Mouse
The Yukon deermouse or Yukon deer mouse (''Peromyscus arcticus'') is a species of rodent in the family Cricetidae. It is endemic to Yukon Territory in Canada. Taxonomy The species was first identified as ''Peromyscus arcticus'' in 1845 by Johann Andreas Wagner. In 1998, following extensive sampling of deermouse specimens throughout northern British Columbia, central Yukon, and northern southeast Alaska, Melanie Wike identified a unique lineage that did not associate with the western deer mouse (''P. sonoriensis'') (then thought to be North American deermouse, or ''P. maniculatus'') or northwestern deermouse (''P. keeni''), both of which also reach the northern limits of their range in the Yukon, and identified it with the previously-described ''P. arcticus''. Genetic studies in 2007 and 2019 further affirmed ''P. arcticus'' as a distinct species, and was later classified as such by the American Society of Mammalogists. Distribution The species ranges within Yukon from Sul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Andreas Wagner
Johann Andreas Wagner (21 March 1797 – 17 December 1861) was a German palaeontologist, zoologist and archaeologist who wrote several important works on palaeontology. Career Wagner was a professor at the University of Munich, and curator of the Zoologische Staatssammlung (State Zoology Collection). He was the author of ''Die Geographische Verbreitung der Säugethiere Dargestellt'' (1844–46). Wagner was a Christian creationist.

Endemic Fauna Of Yukon
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of Canada
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Sauropsida ...

Rodents Of North America
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 ...

Kluane National Park And Reserve
Kluane National Park and Reserve (; french: Parc national et réserve de parc national de Kluane) are two protected areas in the southwest corner of the territory of Yukon. The National Park Reserve was set aside in 1972 to become a national park, pending settlement of First Nations land claims. It covered an area of . When agreement was reached with the Champagne and Aishihik First Nations over an eastern portion of the Reserve, that part—about —became a national park in 1993, and is a unit of the national park system administered co-operatively with Parks Canada. The larger western section remains a Reserve, awaiting a final land claim settlement with the Kluane First Nation. The park borders B.C. to the south, while the Reserve borders both B.C. to the south, and the United States (Alaska) to the south and west. The Reserve includes the highest mountain in Canada, Mount Logan () of the Saint Elias Mountains. Mountains and glaciers, including Donjek Glacier, dominate t ...

Peromyscus Maniculatus
''Peromyscus maniculatus'' is a rodent native to eastern North America. It is most commonly called the eastern deer mouse; when formerly grouped with the western deer mouse (''P. sonoriensis''), it was referred to as the North American deermouse and is fairly widespread across most of North America east of the Mississippi River, with the major exception being the lowland southeastern United States. Like other ''Peromyscus'' species, it can be a vector and carrier of emerging infectious diseases such as hantaviruses and Lyme disease. It is closely related to ''Peromyscus leucopus'', the white-footed mouse. Overview The species in its former broad sense had 61 subspecies, but some of these now belong to ''P. sonoriensis''. They are all tiny mammals that are plentiful in number. The deer mouse is a small rodent that lives in eastern North America and is closely related to the white-footed mouse, ''Peromyscus leucopus''.The New Encyclopædia Britannica. 2007.

Western Deer Mouse
The western deermouse or western deer mouse (''Peromyscus sonoriensis'') is a rodent native to North America. It is widespread throughout the western half of the continent, mainly in areas west of the Mississippi River. Taxonomy It was formerly confused with the eastern deermouse (''P. maniculatus''), with both species being grouped under ''P. maniculatus'' as the North American deermouse. However, due to the significant morphological variation in the species, there was always long-standing confusion over the actual taxonomy of ''P. maniculatus''. A 2019 study found significant genetic divergence within the species and split it into two, with ''maniculatus'' representing the "eastern" group and ''sonoriensis'' representing the "western" group. Description ''P. sonoriensis'' is covered in soft fur that ranges from gray to brown, but all of a distinctive white underside and white feet. As with their close relative, ''P. maniculatus'', they have many subspecies, including a dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
