Long-Term Control of Peary Caribou Numbers by Unpredictable, Exceptionally Severe Snow or Ice Conditions in a Non-equilibrium Grazing System
The number of Peary caribou (Rangifer tarandus pearyi) on the Queen Elizabeth Islands, Canadian High Arctic, is at an all-time known low. Yet some populations are still hunted, and there is no adequate monitoring program in place to determine the consequences. We evaluate information from the Peary caribou population on the south-central Queen Elizabeth Islands as a standard for an accurate and realistic assessment of what controls Peary caribou …
Near-Total Loss of Caribou on South-Central Canadian Arctic Islands and the Role of Seasonal Migration in their Demise
Caribou (Rangifer tarandus) on the south-central Canadian Arctic Islands (Prince of Wales, Somerset, and Russell islands) declined by 98% sometime between 1980 and 1995—a near-total loss of a known genetically distinctive group of Arctic Island caribou. In contrast, caribou on the adjacent Boothia Peninsula seemingly increased by 38% from 1985 to 1995, while experiencing heavy annual hunting pressure. Our evaluation leads us to three primary conc…
A Near-Total Decline in Caribou on Prince of Wales, Somerset, and Russell Islands, Canadian Arctic
The number of caribou (Rangifer tarandus) on Prince of Wales, Somerset, and Russell islands in the south-central Canadian Arctic declined by 98% in 15 years, from an estimated 6048 (16% calves) in 1980 to an estimated 100 (0% calves) in 1995. Those estimates were obtained by systematic aerial surveys that used the same design and methods and comparable survey coverage. We do not have the data needed to determine the rate of decrease between 1980 …
Nonrandom Distribution of Antlers Cast by Peary Caribou Bulls, Melville Island, Northwest Territories
An aerial survey was carried out in July 1987 to determine the pattern of distribution of antlers cast by Peary caribou (Rangifer tarandus pearyi) bulls on north-central and northeastern Melville Island, Northwest Territories, Canada. Four transect lines were flown parallel to the coastal shorelines of Hecla and Griper Bay and adjacent Sabine Bay at distances of about 0.8, 2.4, 5.0, and 10.0 km inland. A four-person survey crew was used in a Bell…
Food Habits of Glaucous Gulls in the Beaufort Sea
During 1973 and 1974, 1877 regurgitated pellets were collected from 15 glaucous gull colonies on inland lakes, river deltas, and coastal reaches of the Beaufort Sea west and east of Tuktoyaktuk, N.W.T. The pellets contained chiefly small rodents, fish, eggs and young of geese and gulls, isopods, berries and grass, and blue mussels. The relative importance of these foods varied among the colonies, both within and between seasons. Predation on youn…
Nursing by Muskox Calves before, during, and after Helicopter Overflights
Nursing bouts by 15 muskox (Ovibos moschatus) calves were measured to evaluate potential use of nursing behaviour as an indicator of muskox responses to helicopters. The muskox calves nursed 225 times during 313 hours of observation: 63% under undisturbed conditions; 12% when helicopter overflights took place; and 25% following those overflights. During exposure to the helicopter, the calf moved to the cow and then sometimes took the opportunity …
