Neovison
''Neogale'' is a genus of mustelid native to the Americas, ranging from Alaska south to Bolivia. Members of this genus are known as New World weasels. Taxonomy Members in this genus were formerly classified into the genera '' Mustela'' and '' Neovison'', but many studies had previously recovered several American species of ''Mustela'', as well as both species within ''Neovison'', to comprise a monophyletic clade distinct from all other members of Mustelinae. A 2021 study found this clade to have diverged from ''Mustela'' during the Late Miocene, between 11.8 - 13.4 million years ago, with all members within the clade being more closely related to one another than to any of the other species in ''Mustela'', and gave it the name ''Neogale'', originally coined by John Edward Gray John Edward Gray, FRS (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frede ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Mink
The American mink (''Neogale vison'') is a semiaquatic species of mustelid native to North America, though human intervention has expanded its range to many parts of Europe, Asia and South America. Because of range expansion, the American mink is classed as a least-concern species by the IUCN. The American mink was formerly thought to be the only extant member of the genus ''Neovison'' following the extinction of the sea mink (''N. macrodon''), but recent studies, followed by taxonomic authorities, have reclassified it and the sea mink within the genus ''Neogale'', which also contains a few New World weasel species. The American mink is a carnivore that feeds on rodents, fish, crustaceans, frogs, and birds. In its introduced range in Europe it has been classified as an invasive species linked to declines in European mink, Pyrenean desman, and water vole populations. It is the animal most frequently farmed for its fur, exceeding the silver fox, sable, marten, and skunk in econo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Mink
The sea mink (''Neogale macrodon'') is a recently extinct species of mink that lived on the eastern coast of North America around the Gulf of Maine on the New England seaboard. It was most closely related to the American mink (''Neogale vison''), with continuing debate about whether or not the sea mink should be considered a subspecies of the American mink (as ''Neogale vison macrodon'') or a species of its own. The main justification for a separate species designation is the size difference between the two minks, but other distinctions have been made, such as its redder fur. The only known remains are bone fragments unearthed in Native American shell middens. Its actual size is speculative, based largely on tooth remains. The sea mink was first described in 1903, after its extinction; information regarding its external appearance and habits stem from speculation and from accounts made by fur traders and Native Americans. It may have exhibited behavior similar to the American m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Weasel
Weasels are mammals of the genus ''Mustela'' of the family Mustelidae. The genus ''Mustela'' includes the least weasels, polecats, stoats, ferrets and European mink. Members of this genus are small, active predators, with long and slender bodies and short legs. The family Mustelidae, or mustelids (which also includes badgers, otters, and wolverines), is often referred to as the "weasel family". In the UK, the term "weasel" usually refers to the smallest species, the least weasel (''M. nivalis''), the smallest carnivoran species. Least weasels vary in length from , females being smaller than the males, and usually have red or brown upper coats and white bellies; some populations of some species moult to a wholly white coat in winter. They have long, slender bodies, which enable them to follow their prey into burrows. Their tails may be from long. Weasels feed on small mammals and have from time to time been considered vermin because some species took poultry from far ...

Neogale Frenata
The long-tailed weasel (''Neogale frenata''), also known as the bridled weasel, masked ermine, or big stoat, is a species of mustelid distributed from southern Canada throughout all the United States and Mexico, southward through all of Central America and into northern South America. It is distinct from the short-tailed weasel (''Mustela erminea''), also known as a "stoat", a close relation in the genus '' Mustela'' that originated in Eurasia and crossed into North America some half million years ago; the two species are visually similar, especially the black tail tip. Taxonomy Originally described in the genus '' Mustela'', a 2021 study reclassified it into the genus ''Neogale'' along with 2 other former ''Mustela'' species, as well as the two species formerly classified in ''Neovison''. Evolution The long-tailed weasel is the product of a process begun 5–7 million years ago, when northern forests were replaced by open grassland, thus prompting an explosive evolution of s ...

Amazon Weasel
The Amazon weasel (''Neogale africana''), also known as the tropical weasel, is a species of weasel native to South America. It was first identified from a museum specimen mislabelled as coming from Africa, hence the scientific name. Taxonomy Originally described in the genus '' Mustela'', a 2021 study reclassified it into the genus '' Neogale'' along with 2 other former ''Mustela'' species, as well as the two species formerly classified in ''Neovison''. Description The largest of the three species of South American weasel, Amazon weasels measure in total length, including a tail long. They have a typical body form for weasels, with a long, slender, torso and short legs and ears. They have short fur which varies from reddish to dark brown on the upper body, and is pale orange-tan on the underparts. A stripe of fur the same colour as that on the upper body runs down the centre of the chest and throat. The whiskers are short and the soles of the feet almost hairless. Females ha ...

Colombian Weasel
The Colombian weasel (''Neogale felipei''), also known as Don Felipe's weasel, is a very rare species of weasel only known with certainty from the departments of Huila and Cauca in Colombia and nearby northern Ecuador (where it is only known from a single specimen). Both its scientific and alternative common name honours the mammalogist Philip "Don Felipe" Hershkovitz. It appears to be largely restricted to riparian habitats at an altitude of . There is extensive deforestation within its limited distribution within the northern Andes of Colombia and Ecuador, and with less than 10 known specimens, it is probably the rarest carnivoran in South America.Novak, R. M. 1999. ''Walker's Mammals of the World''. 6th edition. Johns Hopkins University Press, Baltimore. It is considered vulnerable by the IUCN. It is the second-smallest living carnivoran on average, being only slightly larger than the least weasel (''Mustela nivalis'') and slightly smaller than the stoat or ermine (''M. ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.
