Wolverines will take on animals much bigger than themselves, fighting wolves, reindeer, moose, even bears. They spray a nasty-smelling liquid on trees and bushes to mark their territory. And, like skunks, wolverines can use stink power as a weapon, unleashing the smell when they feel threatened or really cranky.

Adult wolverines have no natural predators, though they do come into conflict with and may be killed by other large predators over territory and food. The worlds total wolverine population is unknown.
The animal exhibits a low population density and requires a very large home range. The range of a male wolverine can be more than kilometres squared square miles while encompassing the ranges of several females with smaller home ranges of roughly — kilometres squared 50 — square miles. Male wolverines use scent glands to mark their territories, however, they share them with several females and are believed to be polygamous. This requirement for large territories brings wolverines into conflict with human development.
Wolverine mating season is in the summer, however, the actual implantation of the embryo blastocyst in the uterus is stayed until early winter, delaying the development of the fetus. Females give birth to a litter of 2 — 4 young in the spring after a gestation period of 30 — 50 days. Kits sometimes live with their mother until they reach their own reproductive age at about 2 years old.
Females will often not produce young if food is scarce. Kits develop very quickly, reaching adult size within their first year. The life span of a wolverine may reach anywhere from 7 to 13 years. Hunting and trapping further reduce their numbers, causing wolverines to disappear from large parts of their former range.
