Book Description
"During spring 1976-79 we marked and recaptured polar bears in northern Labrador. Thirty-seven polar bears were captured and individually tagged. Most were found along the interface between the coastal landfast ice and the drifting pack ice, especially around the mouths of bays. The mark and recapture data indicated a low population (60-90 bears) in the area. Fifty to 80% fewer polar bears and tracks were seen per 100 km of potential habitat surveyed than recorded for other areas of the Arctic. This also indicates a smaller population"--Abstract.

Book Description
These proceedings provide an overview of the ongoing research and management activities on polar bears in the circumpolar arctic. Together with the previous 12 proceedings, they provide an historic record of international efforts in protecting polar bears from over-harvest and document more recent concerns of threats arising from increased human activities in both the Arctic and in regions far beyond the realm of polar bears. More proactive management is needed to address limitations in the knowledge of population dynamics. New information indicates that the greatest future challenges to polar bear conservation may be ecological change in the Arctic due to climate change and pollution. The complex, global nature of the issues requires international cooperation and development of diverse, new approaches to address them.
