On 2 October 2007, we observed evidence of at least one brown bear (Ursus arctos) predating and caching broad whitefish (Coregonus nasus) at Pete’s Creek, a tributary of the Mackenzie River, Northwest Territories. While predation on whitefish by brown bears has been reported as traditional...
Wolf Reproduction in Response to Caribou Migration and Industrial Development on the Central Barrens of Mainland CanadaDownload
Reproductive success of mammals is greatly influenced by food availability. Where wolves (Canis lupus) prey on migratory barren-ground caribou (Rangifer tarandus), caribou migration patterns strongly influence food availability for wolves. However, industrial development in formerly undeveloped...
Lightning and fire characteristics within the Northwest Territories (NWT) jurisdiction of the Mackenzie Basin between 1994 and 1999 are examined using data from the lightning detection network operating in the NWT and from the national Large Fire Database maintained by the Canadian Forest...
Wolves (Canis lupus) on the Canadian barrens are intimately linked to migrating herds of barren-ground caribou (Rangifer tarandus). We deployed a Global Positioning System (GPS) radio collar on an adult female wolf to record her movements in response to changing caribou densities near her den...
We examined spatiotemporal variation in the physical, chemical, and biological characteristics of pristine streams that represent a range of conditions near Lac de Gras in the Barrenlands region of the Northwest Territories, Canada. Principal component analysis organized streams into four groups...
