A 2005 study compared the mitochondrial DNA sequences of modern wolves with those from 34 specimens dated between 1856 and 1915. The historic population was found to possess twice the genetic diversity of modern wolves, [ 5 ] [ 6 ] which suggests that the mDNA diversity of the wolves eradicated from the western U.S. was more than twice that of ...
The wolf (Canis lupus; [b] pl.: wolves), also known as the grey wolf or gray 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 grey wolves, as popularly understood, only comprise naturally-occurring wild subspecies.
Ordinary pet food is inadequate, as an adult wolf needs 1–2.5 kg (2–5 lbs) of meat daily along with bones, skin and fur to meet its nutritional requirements. Wolves may defend their food against people, and react violently to people trying to remove it. [2] The exercise needs of a wolf exceed the average dog's demand.
Caniformia is a suborder within the order Carnivora consisting of "dog-like" carnivorans. They include dogs (wolves, foxes, etc.), bears, raccoons, and mustelids. [1] The Pinnipedia (seals, walruses and sea lions) are also assigned to this group.
Single wolves or mated pairs typically have higher success rates in hunting than do large packs; single wolves have occasionally been observed to kill large prey such as moose, bison and muskoxen unaided. [1] [2] This contrasts with the commonly held belief that larger packs benefit from cooperative hunting to bring down large game. [2]
Their frequency varies with geographical location and historical period, but overall wolf attacks are rare. Wolves today tend to live mostly far from people or have developed the tendency and ability to avoid them. Experts categorize wolf attacks into various types, including rabies-infected, predatory, agonistic, and defensive.
The front footprints are 7–9 cm (2.8–3.5 in) long and 5.5–7 cm (2.2–2.8 in) wide, and those of the hind feet are 6.5–9 cm (2.6–3.5 in) long and 6.5–8.5 cm (2.6–3.3 in) wide. [24] One feature that differentiates the maned wolf's footprint from those of other South American canids is the proximal union of the third and fourth digits.
The Himalayan wolf (Canis lupus chanco) is a canine of debated taxonomy. [3] It is distinguished by its genetic markers, with mitochondrial DNA indicating that it is genetically basal to the Holarctic grey wolf, genetically the same wolf as the Tibetan and Mongolian wolf, [4] [5] [3] and has an association with the African wolf (Canis lupaster).
