Wolverines and their prey in southern Norway
Wolverines (Gulo gulo) recolonized the Snøhetta plateau in southern Norway in 1976–1979 after an absence of over 50 years. This is presently the southernmost part of the wolverine's distribution and the only area where it coexists with wild reindeer (Rangifer tarandus) in western Europe. Other,...

Wolverines (Gulo gulo) recolonized the Snøhetta plateau in southern Norway in 1976–1979 after an absence of over 50 years. This is presently the southernmost part of the wolverine's distribution and the only area where it coexists with wild reindeer (Rangifer tarandus) in western Europe. Other, larger predators in the Scandinavian ecosystem, the wolf (Canis lupus), lynx (Lynx lynx), and brown bear (Ursus arctos), have been absent from the area since the beginning of this century. We monitored wolverine numbers, reproduction, and diet during the denning period and studied the effects of abundance of different prey species on wolverine reproduction.
