[Ian Stirling; Dennis Andriashek; Wendy Calvert; Canadian Wildlife Service.] -- Mark and recapture data suggests a population size of Baffin Island (Inuktitut: ᕿᑭᖅᑖᓗᒃ, Qikiqtaaluk IPA: [qikiqtaːluk], French: Île de Baffin, Terre de Baffin), in the Canadian territory of Nunavut, is the largest island in Canada and the fifth-largest island in the area iskm 2 (, sq mi) and its population is ab ( census).

The mean age of both females and males increased over the study, litter production rate and natality declined and body length of adults decreased. Dynamics of body mass were suggestive of cyclical changes over time and variation in body mass of both adult females and Cited by:   A peer-reviewed paper published last year (Rode et al.

Loss of sea ice has had extensive individual and population-level impacts on polar bears (Ursus maritimus) across the Arctic because the species requires sea ice as a platform on which to hunt.

These impacts include declines in body condition, survival, and subpopulation size, and an increasing amount of time on land during summer in some areas.

This work aims to understand and quantify the. During the winter months in the Arctic regions, it is dark all day long, and the polar bear populations gather for the long winter months.

Until recently, the sea ice habitat of polar bears was understood to be variable, but environmental variability was considered to be cyclic or random, rather than progressive. Harvested populations were believed to be at levels where density effects were considered not significant. However, because we now understand that polar bear demography can also be influenced by progressive change in the.
