The Latin lupus is a Sabine loanword.
Europe[ edit ] Linnaeus gave the black wolves of Europe the binomial name Canis lycaon, under the assumption that the species was distinct from grey and white coloured wolves. Cuvier and other naturalists largely followed his example. They also occurred in the mountains of Friuli Italy and around Kotor Montenegro.
Black wolves were also reported in Siberia as the Vekvoturian Mountain-wolf. These wolves were completely black and were bigger than the more common grey variety. Their pelts were considered exotic enough to be sold for 3—4 times the price established for more common colour morphs. Asia[ edit ] Black wolves were occasionally reported in Asia.
The "Derboun" of the Arabian mountains and southern Syria was a small black wolf which apparently was considered by the Arabs to be more closely related to dogs, as they freely ate its flesh like any other game, unlike with regular wolves which had an unpleasant odour.
Small populations inhabit Ladakh. He stated that they were "perfectly black", except the females which were described as having a white spot on the breast. Bartram also described a "black wolf-dog of the Florida Indians " which was identical to the local wolves, save for the fact that it could barkand could be trusted around horses.
A chieftain accepting a gift of black wolf fur was seen as an act of reconciliation. They apparently produced a foul odour. Such crosses in the wild have been reported and the wolf in captivity crosses readily with dogs.
Some years ago at Circle, Alaska, a wolf hung around the settlement for some time and some of the dogs were seen with it. The people thought that the wolf was a female attracted to the dogs during the breeding period.
However, considerable variability is probably inherent in the species, enough perhaps to account for the variations noted in the park and in skins examined. The amount of crossing with dogs has probably not been sufficient to alter much the genetic composition of the wolf population.
Barsh, a professor of genetics and pediatrics at the Stanford University School of Medicine used molecular genetic techniques to analyze DNA sequences from wolves, half of them black, in Yellowstone National Parkwhich covers parts of WyomingMontana and Idaho.
It was discovered that a gene mutation responsible for the protein beta-defensin 3known as the K locusis responsible for the black coat color in dogs.
Barsh and his colleagues concluded that the mutation arose in dogs 12, toyears ago, with a preferred date of 46, years ago after comparing large sections of wolf, dog and coyote genomes. Wayne, a canine evolutionary biologist, stated that he believed that dogs were the first to have the mutation.
He further stated that even if it originally arose in Eurasian wolves, it was passed on to dogs who, soon after their arrival, brought it to the New World and then passed it to wolves and coyotes.
These scientists argue that the melanistic Indian wolf "challenges the hypothesis of complete disappearance of the gene responsible for the black coat colour from the gene pool of the Old World wolves" and "may indicate the recent re-introduction of the gene from dogs to Indian wolves through hybridisation, or recurrence of an independent mutation in Indian wolves.
Dr Barsh ruled out camouflageas wolves have few natural predators, and there is no evidence that a black coat color leads to any increase in hunting success rates. Barsh observed that beta-defensin is involved in providing immunity to viral and bacterial skin infectionswhich might be more common in forested, warmer environments.Le Coyote (Canis latrans), du nahuatl coyotl (prononcé [k w a j ɔ t ɬ] Écouter) est une espèce de canidés du genre Canis originaire d'Amérique du initiativeblog.com est plus petit que son parent proche, le loup gris (C.

The Ethiopian, or Abyssinian, wolf (C. simensis) inhabits the highlands of Ethiopia; until recently it was considered a jackal.
Yellowstone National Park ensures the long-term viability of wolves in Greater Yellowstone and provides a place for research on how wolves may affect many aspects of the ecosystem.
Introduction. The gray wolf (Canis lupus) is a native species that was likely extirpated from California in the s. The gray wolf is now returning to California on its own by dispersal of individuals from populations in other states. The California Department of Fish and Wildlife (CDFW) is working to monitor this recovering endangered species.
