Canada has an important responsibility for the research, conservation, and management of
polar bears (Ursus maritimus Phipps, 1774) because the majority of polar bears in the world …

Arctic sea ice has changed dramatically, especially during the last decade and continued
declines in extent and thickness are expected for the decades to come. Some ice-associated …

Polar bears are susceptible to climate warming because of their dependence on sea ice,
which is declining rapidly. We present the first evidence for a genetically distinct and …

Populations of bears in Asia are vulnerable to extinction and effective monitoring is critical to
measure and direct conservation efforts. Population abundance (local density) or growth (λ) …

Satellite telemetry (ST) has played a critical role in the management and conservation of
polar bears (Ursus maritimus) over the last 50 years. ST data provide biological information …

This paper compares and contrasts the ecosystems of the Barents and Chukchi Seas.
Despite their similarity in a number of features, the Barents Sea supports a vast biomass of …

The Arctic is becoming warmer at a high rate, and contractions in the extent of sea ice are
currently changing the habitats of marine top-predators dependent on ice. Polar bears …

Recent observations suggest that polar bears (Ursus maritimus) are increasingly using land
habitats in some parts of their range, where they have minimal access to their preferred prey …

Animals that must hunt and kill for at least part of their living are inherently interesting to
many people and the role that carnivores play in biological communities attract interest from …

Remote sensing can be a valuable alternative or complement to traditional techniques for
monitoring wildlife populations, but often entails operational bottlenecks at the image …
