Commentary
In conclusion, the economic system has created a greater need for conservation than ever existed when immediate ecosystems regulated human populations and human endeavour in the north. Reasons include an expansion of what are considered resources, a shift from renewable (wildlife) to non-renewable (mineral) resources, and an increase in the importance of northern activities which extends well beyond the north. Thus, conservation has required the …
Altitudinal Movements and Summer Habitat Preferences of Woodland Caribou in the Kluane Ranges, Yukon Territory
The altitudinal movements, preferred topography and plant communities of 150 to 200 woodland caribou (Rangifer tarandus caribou) were recorded for two summers. Nine subalpine or alpine tundra communities constituting their major summer range were quantitatively described. Caribou calved in shrub communities between 1300 and 1450 m, moving upward as the summer progressed. Stags and associated juveniles preferred higher elevations than did other gr…
Food Habits of Wolves in Kluane National Park
The food habits of wolves (Canis lupus) were studied at two different den-sites in Kluane National Park in the southwest of the Yukon Territory, in 1972 and 1973, as part of an assessment of predator-prey dynamics in that newly-designated reserve. No published data exist on the diets of wolves in northern British Columbia or the Yukon Territory; the closest available information concerns the wolf populations of Alaska
Significance of Brooding to the Energy Demands of Alaskan Rock Ptarmigan Chicks
Rock ptarmigan (Lagopus mutus) chicks are brooded periodically during the first few days of life; longer in cold and rainy weather. Computed minimum foraging time in adverse weather conditions is 96 minutes/24 hours. Crop analysis and calorimetry of the 6 major food items show that a full crop may contain up to 0.47 kcals. Energy requirements were calculated for both an 18-gram chick and a 30-gram chick. The 18-gram chick required between 34 and …
