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…
The Polar Bear Management Agreement for the Southern Beaufort Sea
Polar bears (Ursus maritimus) of the southern Beaufort Sea population, distributed from approximately Icy Cape, west of Point Barrow, Alaska, to Pearce Point, east of Paulatuk in Canada, are harvested by hunters from both countries. In Canada, quotas to control polar bear hunting have been in place, with periodic modifications, since 1968. In Alaska, passage of the United Sates Marine Mammal Protection Act (MMPA) of 1972 banned polar bear hunting…
Distribution, Characteristics, and Use of Earth Dens and Related Excavations by Polar Bears on the Western Hudson Bay Lowlands
Polar bears fasting on land along the western coast of Hudson Bay during the open water period, from late July through early November, excavate three different types of structures, which we termed pits, deep dens, and shallow dens. Pits were shallow excavations found on the tops of banks or beach ridges, whereas both deep and shallow dens were dug into frozen peat banks. Pits were used as temporary resting places. The function of shallow dens is …

Habitat preferences of polar bears in the western Canadian Arctic in late winter and spring
Between late March and May, from 1971 through 1979, we surveyed 74,332 km 2 of sea-ice habitatin the eastern Beaufort Sea and Amundsen Gulf in the western Canadian Arctic. We defined seven sea-ice habitat types and recorded sightings of polar bears and their tracks in each to determine their habitat preferences. 791 bears (including cubs) and 6454 sets of tracks were recorded. 42.3%, 39.7%, and 15.6% of the bears were seen on floe-edge, moving ic…
Underwater Vocalizations as a Tool for Studying the Distribution and Relative Abundance of Wintering Pinnipeds in the High Arctic
Recordings of the underwater vocalizations of ringed seals, bearded seals and walruses were made in the High Arctic between late March and late June 1980 and 1981, to evaluate the potential for using sub-ice vocalizations to study the distribution and relative abundance of wintering pinnipeds. Most of the calls made by these three species are identified and an initial lexicon is presented. Ringed seal vocalizations were more frequent in late Apri…
Evironmental threats to marine mammals in the Canadian Arctic
The Arctic Ocean is the home of three major groups of mammals that depend on the sea for survival and show varying degrees of adaptation for maritime life. Most fully adapted are the whales (Cetacea), which never leave the water, and the seals and walruses (Pinnipedia) that feed entirely at sea but emerge onto land or ice for pupping and basking. Less exclusively marine are two species of the order Carnivora—Polar Bears ( Ursus maritimus ), that …
