Aug 16, 2019 · A scanning electron microscope reveals the smoothness of the middle parts of wolverine guard hairs. Images: Boris Pavlin , Carinthia University of Applied Sciences, 2012. Sadly, there is still no clear understanding of why wolverine fur is so effective – or, to be precise, why it’s so easy to brush frost off before it becomes a problem.

The wolverine is a medium sized animal (14-44 lbs.) with males being slightly larger than females. Wolverines are dark brown with two yellowish stripes running down the sides of the body from the shoulders to the base of the tail. Some animals possess lighter areas on the chest, which can be used to distinguish individual animals. Their heads are l...
Wolverines have dense, heavy skulls that are wedge-shaped. The rostrum is short, and the dorsal portion of the skull has prominent sagittal, and occipital crests. The sagittal crest often overhangs the posterior portion of the skull, especially in older males. Wolverines have a barrel shaped condylar process on the mandible that fits tightly into t...
Wolverines tracks are found in circumboreal areas of the world. In the Continental United States, wolverines are found in the Rocky and Cascade mountain ranges of the west. Wolverines inhabit both forested and open habitats such as alpine tundra and subalpine parkland. In Washington, wolverines primarily use high elevation mixed montane and mixed s...
Wolverines were extirpated in Washington in the early 1900’s due to overharvesting for the fur trade. In the 1990’s wolverines were detected in the Cascade Mountain Range. The animals that have recolonized the Cascades are genetically related to animals in the Coast range of British Columbia.
Wolverines are typically solitary except for females with young. Recent studies however are beginning to point towards more complicated intraspecific social relationships. Male wolverines have been documented interacting positively with their offspring, including male offspring, from previous years into the sub-adult life stage.
Wolverines are polygamous with one male doing most of the breeding over a large area during the April-August breeding season. Females dig natal dens underneath logs and rock piles in rugged subalpine and alpine areas away from human infrastructure. Dens consist of a tunnel system with typically 2 kits born in a chamber at ground level. Den sites ha...
Wolverine kits are typically born Jan-April. Kits first leave their natal den after the first period of warmer weather (several days of above freezing temperatures). The kits are then typically moved to a maternal den site. The kits are weaned at 7-8 weeks and typically disperse at 13 months, although the kits may remain in the mother’s territory f...
Wolverines have very large home ranges that they typically cover over a period of several weeks often in figure 8 patterns. Male wolverines have home ranges in Washington that can approach as much as 3,000 square kilometers during the breeding season. Females have smaller home ranges, and females with young kits have the smallest home range of all....
Wolverines are carnivores that both hunt and scavenge. Wolverine have an excellent sense of smell that helps them locate carcasses; and their aggressiveness towards other predators enables them to push other carnivores off carcasses and kills. Wolverines, despite their masterful ability to scavenge, are also very capable hunters. Ungulates are hunt...
In one study in the North Cascades of Washington, multiple radio collared animals died as the result of interaction with other carnivores, likely cougars. Gray wolves will also occasionally kill wolverines. Intraspecific mortality is also known. Males will kill the offspring of other males, and the dominant animal within a home range may kill dispe...
Feb 28, 2022 · Wolverine is considered by Arctic Inuit to be the most effective hood ruff, but wolf, coyote or fox also work well. Research suggests that the uneven length of natural fur hairs disrupts air currents that can rob heat from around the face. Whatever the reason, a fur-trimmed hood is a “must” in cold temperatures; it really works. #2: Après ski.

The long guard hairs provide a long full ruff that traps a lot of air, providing a very warm pocket around your face. The hair is thick and strong with few breakages, which makes a durable long-lasting ruff. One downfall a wolf has is its under-fur which is long and thick.
Sep 4, 2023 · The outer layer is made up of long, coarse guard hairs that repel water and snow, preventing them from reaching the inner layer. The inner layer, on the other hand, is dense and soft, trapping air close to the wolverine’s body and creating a warm layer of insulation.
