. The pelage is long and varies in color from almost blond to dark brown, with two distinctive yellowish stripes that run from the top of the neck to the rump. White patches on the throat, belly or limbs are common. The head is large, with a broad forehead, broad nose, and rounded ears. The limbs are relatively short and the tail is bushy. The feet are large, with well-developed claws. The skull is exceptionally robust and broad, with a well-developed sagittal crest. Dental formula: 13/3, C 1/1, P 4/4, M 1/2 = 38. The teeth are big and strong; the carnassials are very large.

Wolverines are found in mature conifer forests in the taiga and in the treeless tundra. They are inhabitants of remote northern areas where there are few humans. Wolverines make greater use of forested areas during winter, and greater use of tundra during summer. Altitudinal movements may also occur seasonally, with higher elevations being occupied during the summer and lower altitudes during the winter, probably because of snow accumulation and prey abundance. In central

from whitebark pine (Pinus albicaulis) in summer to lower elevation Douglas-fir (Pseudotsuga menziezii) and lodgepole pine (Pinus contorta) communities in winter. Wolverines also preferred northerly aspects, but avoided roads and ungulate winter range. In

, radio-telemetry revealed that Wolverines negatively responded to human disturbance within occupied habitat; males tended to avoid helicopter skiing areas. Habitat associations of females were more complex, but in the summer they avoided roads and recently logged areas. In the Columbia Mountains, where winter recreation is widespread, females prefer alpine and avalanche environments where Hoary Marmot (Marmota caligata) and Columbia Ground Squirrel prey are found in the summer. During the winter, females tend to avoid areas with helicopter and backcountry skiing, and prefer areas where Moose (Alces alces) can be found.

The diet includes the carcasses of large ungulates, such as Moose and Reindeer (Rangifer tarandus). In many areas, Wolverines are dependent on the ability of larger predators, especially Gray Wolves, to provide kills. In coastal areas, they also feed on the carcasses of whales and seals that wash ashore. Wolverines also prey opportunistically on deer, sheep, small mammals (rodents such as Marmota and Myodes, lagomorphs, and ground squirrels), birds, and eggs. Berries, nuts and fungus are occasionally eaten. Within two study areas in

, scat analysis revealed a diet that varied regionally and seasonally: Moose, Reindeer, and Hoary Marmots were abundant and common prey items within both study areas. Mountain Goats (Oreamnos americanus) and North American Porcupine (Erithizon dorsata) were more frequent prey items in the Columbia Mountains, while Snowshoe Hare (Lepus americanus) and American Beaver (Castor

) were more frequent prey items in the Omineca Mountains. Reindeer, Hoary Marmots, and North American Porcupines were found in significantly higher frequencies in the diet of reproductive females. Predation on ungulates (such as Reindeer)is facilitated when there is deep snow. Wolverines kill larger prey by a bite at the neck or throat. Small rodents may be chased, pounced upon, or dug out of the ground. Excess food is cached for later use and is covered with earth or snow, or sometimes wedged in the forks of trees. In

, cache sites were in stands of black spruce (Picea mariana) or mixed-wood of high complexity, dominated by conifers, and in which the trembling aspen (Populus tremuloides) and balsam poplar (Populus balsamifera) component consisted of mostly dead or dying trees. These sites offered relatively good visibility of the surrounding area; caches were never located in the very dense homogenous spruce stands. Cache sites were classified as “simple caches”, composed of a single feeding site and/or excavation, and “cache complexes”, involving one or more feeding “stations”, latrines, resting sites, and climbing trees that may have been used as avenues of escape from competitors or predators. The better used cache complexes were accessed by numerous well-used trails made by the Wolverines themselves. Caches contained the remains of Moose that were believed to have been killed by Wolves.

in a single year. Females often reproduce with the same male in subsequent breeding years, but sometimes change their partner, possibly as a consequence of a change in the territory-holding male in the area. Females are monoestrous and apparently give birth about every two years. Mating occurs from May to August. Ovulation is induced; implantation of the fertilized eggs into the uterus is delayed until the following November to March. Births occur from January to April, after a total gestation period of 215-270 days. Maternal dens are located in alpine, subalpine, taiga, or tundra habitat; reports of dens in low elevation, densely forested habitats are rare. Dens in

Red Listt. Wolverines are harvested for their pelt; although their fur is not used widely in commerce it is valued for parkas. Fur trapping has contributed to a decline in numbers and distribution of the Wolverine. Wolverines are also intensely hunted because they are considered a nuisance animal: they follow traplines and devour trapped furbearers, they break into cabins and food caches, they allegedly prey on domestic reindeer, and they attack sheep. Protection and recovery measures are needed to restore populations acrossits previously known range.
