BBC – Research shows wolverine numbers are falling across North America. Their decline has been linked to less snow settling as a result of climate change. The study is the first to show a decline in the abundance of any land species due to vanishing snowpack. Details of the wolverine’s decline are published in Population Ecology. The wolverine lives in boreal forest across Scandinavia, northern Russia, northern China, Mongolia and North America, where it ranges mostly across six provinces of western Canada. This largest member of the weasel family eats carrion and food it hunts itself, including hares, marmots, smaller rodents and young or weakened ungulates. It has evolved for life on the snowpack, having thick fur and outsized feet that help it move across and hunt on snow.
