Gray Wolf

Tuesday, 27 December 2016

The gray wolf is the largest extant member of the Canidae, excepting certain large breeds of domestic dog. Gray wolf weight and size can vary greatly worldwide, tending to increase proportionally with latitude as predicted by Bergmann’s Rule,[9] with the large wolves of Alaska and Canada sometimes weighing 3–6 times more than their Middle Eastern and South Asian cousins. On average, adult wolves measure 105–160 cm (41–63 in) in length and 80–85 cm (32–34 in) in shoulder height. The tail measures 29–50 cm (11–20 in) in length. The ears are 90–110 millimetres (3.5–4.3 in) in height, and the hind feet are 220–250 millimetres (8.7–9.8 in). The mean body mass of the extant gray wolf is 40 kg (88 lb), with the smallest specimen recorded at 12 kg (26 lb) and the largest at 80 kg (176 lb). Gray wolf weight varies geographically; on average, European wolves may weigh 38.5 kilograms (85 lb), North American wolves 36 kilograms (79 lb) and Indian and Arabian wolves 25 kilograms (55 lb). Females in any given wolf population typically weigh 5–10 lbs less than males. Wolves weighing over 54 kg (120 lbs) are uncommon, though exceptionally large individuals have been recorded in Alaska, Canada, and the forests of western Russia. The heaviest recorded gray wolf in North America was killed on 70 Mile River in east-central Alaska on July 12, 1939 and weighed 79.4 kilograms (175 lb).

Coywolf

Saturday, 24 December 2016

Coywolf (sometimes called woyote) is an informal term for a canid hybrid descended from coyotes and one of three other North American Canis species, the gray, eastern and red wolf. Coyotes are closely related to eastern and red wolves, having diverged 150,000–300,000 years ago and evolved side by side in North America, thus facilitating hybridization. In contrast, hybrids between coyotes and gray wolves, which are Eurasian in origin and diverged from coyotes 1–2 million years ago, are extremely rare. Such hybridization in the wild has only been confirmed in isolated gray wolf populations in the southern USA, while several specimens were produced in captivity via artificial insemination from sperm extracted from northwestern gray wolves introduced to female western coyotes

The Wolf in Switzerland

Wednesday, 5 November 2014

For many years the word wolf put fear in the hearts of people. It has been described as savage, evil, diabolical, and ravenous. But this is far from the truth. Wolves are very social animals with a very complex social hierarchy. A pack of wolves will consist of mothers, fathers, pups, aunts, uncles, and grandparents. The entire pack claims responsibility for each pup, should the parents be out hunting or even killed, the pups will be adopted by another mother. Wolves were once numerous throughout Switzerland, but due to fear of this misunderstood animal, they have been hunted to the point where they have become totally extinct in Switzerland. But now, the wolf is back…
