Wolf Hybrids
Wolf Hybrids By Claudine Wilkins and Jessica Rock, Founders of Animal Law Source™ DEFINITION By definition, the wolf-dog hybrid is a cross between a domestic dog (Canis familiaris) and a wild Wolf (Canis Lupus). Wolves are the evolutionary ancestor of dogs. Dogs evolved from wolves through thousands of years of adaptation, living and being selectively bred and domesticated by humans. Because dogs and wolves are evolutionarily connected, dogs and wolves can breed together. Although this cross breeding can occur naturally, it is a rare occurrence in the wild due to the territorial and aggressive nature of wolves. Recently, the breeding of a dog with a wolf has become an accepted new phenomenon because wolf-hybrids are considered to be exotic and prestigious to own. To circumvent the prohibition against keeping wolves as pets, enterprising people have gone underground and are breeding and selling wolf-dog hybrids in their backyards. Consequently, an increase in the number of hybrids are being possessed without the minimum public safeguards required for the common domestic dog. TRAITS OF DOGS AND WOLVES Since wolf hybrids are a genetic mixture of wolves and dogs, they can seem to be similar on the surface. However, even though both may appear to be physically similar, there are many behavioral differences between wolves and dogs. Wolves raised in the wild appear to fear humans and will avoid contact whenever possible. Wolves raised in captivity are not as fearful of humans. This suggests that such fear may be learned rather than inherited. Dogs, on the other hand, socialize quite readily with humans, often preferring human company to that of other dogs. -

It was outside the scope of this study to conduct a complete analysis of all potential factors in the disappearance. In north Greenland, a small population of up to 32 wolves during optimal years continues to exist, and dispersers reach north-east Greenland occasionally.

(M.A., Applied Geography) Predictive ecological modeling of grey wolf (Canis lupus) movement using agent-based modeling and GIS Thesis directed by Associate Professor Steve Jennings, Emeritus ABSTRACT There is a wide-spread loss of large predators being witnessed across ecosystems globally. The large, apex predators are either displaced from habitat destruction, or killed directly by anthropogenic disturbances. We need apex predators for tri-trophic cascades, mesopredator control, and to promote biodiversity in ecosystems. Previous ecology research highlights how a tri-trophic cascade, or a series of dynamic interactions between predator, prey, and vegetation, is vital for allowing the ecosystem to be resilient and sustainable to disturbances. Technology equips us with new methods of exploring ecosystem functions, animal behavior, and how changing landscapes affect animal movement. By constructing an ABM for grey wolves in North America, we experimented with different predator efficiencies to test how grey wolves could possibly recolonize Moffat County, Colorado. Results from the ABM showed patterns of wolf occupation along low-elevation, river valleys, the wolves did not impact or disrupt prey population demographics, and wolves were able to recolonize the region despite the different predator efficiencies. -
Red Wolf Brochure
U.S. Fish & Wildlife Service Endangered Red Wolves The U.S. Fish and Wildlife Service is reintroducing red wolves to prevent extinction of the species and to restore the ecosystems in which red wolves once occurred, as mandated by the Endangered Species Act of 1973. According to the Act, endangered and threatened species are of aesthetic, ecological, educational, historical, recreational, and scientific value to the nation and its people. On the Edge of Extinction The red wolf historically roamed as a top predator throughout the southeastern U.S. but today is one of the most endangered animals in the world. Aggressive predator control programs and clearing of forested habitat combined to cause impacts that brought the red wolf to the brink of extinction. By 1970, the entire population of red wolves was believed to be fewer than 100 animals confined to a small area of coastal Texas and Louisiana. In 1980, the red wolf was officially declared extinct in the wild, while only a small number of red wolves remained in captivity. During the 1970’s, the U.S. Fish and Wildlife Service established criteria which helped distinguish the red wolf species from other canids. From 1974 to 1980, the Service applied these criteria to find that only 17 red wolves were still living. Based on additional Greg Koch breeding studies, only 14 of these wolves were selected as founders to begin the red wolf captive breeding population. The captive breeding program is coordinated for the Service by the Point Defiance Zoo & Aquarium in Tacoma, Washington, with goals of conserving red wolf genetic diversity and providing red wolves for restoration to the wild. -

Today, people can purchase these garments in many stores all over the world. 20 5 Changing Colors with the Seasons The fur of some Arctic animals changes from the woodland colors of the fall to pure white like winter snow. If they kept their woodland colors, these Arctic animals would stand out in the white snow and they would be unprotected. So, their fur must change to white. As a result, the animals can hide in the snow from their enemies and search safely for food. -
Long-Term Trends in Food Habits of the Raccoon Dog, Nyctereutes Viverrinus, in the Imperial Palace, Tokyo
Bull. Natl. Mus. Nat. Sci., Ser.

A total of 95 taxa (including 58 taxa identi- fied as genera or species) of plant seeds were detected from 163 collected feces in 164 weekly sur- veys. Among them, eight taxa were selected as the food resources for the raccoon dogs in the Imperial Palace. The intakes of these taxa showed seasonal succession, i.e. Aphananthe aspera in January, Idesia polycarpa in February, Rubus hirsutus from May to July, Cerasus spp. in May and June, Morus spp. in June, Machilus thunbergii in July and August, Aphananthe aspera from Sep- tember to December until the following January, and also Ficus erecta in September and Celtis sinensis in December. In March and April, plant harvest is rather poor, and therefore raccoon dogs feed on the inside endosperm of Ginkgo biloba and family Fagaceae to supply the insufficient nutrients as observed by broken seed coats from feces.
