Global wolf range based on IUCN's 2023 assessment. [1] The wolf (Canis lupus; [b] pl.: wolves), also known as the gray wolf or grey wolf, is a canine native to Eurasia and North America. More than thirty subspecies of Canis lupus have been recognized, including the dog and dingo, though gray wolves, as popularly understood, only comprise ...
The Mexican wolf is the smallest of North America's gray wolves, [9] while also being one of the more colorful and visually-distinctive subspecies. It is similar to the Great Plains wolf (C. l. nubilus), albeit distinguishable by a smaller, narrower skull and darker, more variable pelage (which is typically a sandy- to yellowish-gray with "highlights" of blacks, browns and some whites).
Canis is a genus of the Caninae which includes multiple extant species, such as wolves, dogs, coyotes, and golden jackals. Species of this genus are distinguished by their moderate to large size, their massive, well-developed skulls and dentition, long legs, and comparatively short ears and tails. [3]
Canidae (/ ˈkænɪdiː /; [ 3 ] from Latin, canis, " dog ") is a biological family of dog-like carnivorans, colloquially referred to as dogs, and constitutes a clade. A member of this family is also called a canid (/ ˈkeɪnɪd /). [ 4 ] The family includes three subfamilies: the Caninae, and the extinct Borophaginae and Hesperocyoninae. [ 5 ]
There are 38 subspecies of Canis lupus listed in the taxonomic authority Mammal Species of the World (2005, 3rd edition). These subspecies were named over the past 250 years, and since their naming, a number of them have gone extinct. The nominate subspecies is the Eurasian wolf (Canis lupus lupus).
Great Plains wolf. The Great Plains wolf (Canis lupus nubilus), also known as the buffalo wolf or loafer, is a subspecies of gray wolf that once extended throughout the Great Plains, from southern Manitoba and Saskatchewan in Canada southward to northern Texas in the United States. [5] The subspecies was thought to be extinct in 1926, until ...
Today, the nomenclature is regulated by the nomenclature codes. There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, and species. In addition, domain (proposed by Carl Woese) is now widely used as a fundamental rank, although it is not mentioned in any of the nomenclature codes, and is a synonym for ...
The group found deficiencies in the previous study's selection of specimens and the findings drawn from the different techniques used. Therefore, the group argues that both the red wolf and the eastern wolf remain genetically distinct North American taxa. [74] This was rebutted by the authors of the earlier study. [122]
