Polar Bears
Presents an introduction to the polar bear, discussing its evolution, physical characteristics, life cycle, predatory behavior, habitat, and the threats to its existence from global warming.
Polar Bears
In addition to agenda and minutes of meeting, this contains: summary of Ursus maritimus population status; evaluation of polar bear in relation to 1996 IUCN Red List of Threatened Animals; resolutions; press release; national reports on research in Canada, Greenland, Norway, Russia, and Alaska.
Bears of the World
Bears have fascinated people since ancient times. The relationship between bears and humans dates back thousands of years, during which time we have also competed with bears for shelter and food. In modern times, bears have come under pressure through encroachment on their habitats, climate change, and illegal trade in their body parts, including the Asian bile bear market. The IUCN lists six bears as vulnerable or endangered, and even the least concern species, such as the brown bear, are at risk of extirpation in certain countries. The poaching and international trade of these most threatened populations are prohibited, but still ongoing. Covering all bears species worldwide, this beautifully illustrated volume brings together the contributions of 200 international bear experts on the ecology, conservation status, and management of the Ursidae family. It reveals the fascinating long history of interactions between humans and bears and the threats affecting these charismatic species.
Polar Bears
* Spectacular photographs of the polar bear: the largest carnivore to walk the earth today* Follows the bears across the Arctic, from settlements to forests, pack-ice to tundra* Contains a collection of evocative essays and poetry* Foreword by Hubert ReevesA symbol of strength, survival despite hardship and - more recently - the perils of global warming, the polar bear wears many different faces across the world. Polar Bears: A Life Under Threat is an uncompromising exploration of the animal behind the mythos. Rawicki's anthology transports us to the Arctic: the bears' home territory. His photographs depict playful cubs, hunting mothers and solitary adults on their yearly migration. The bear...
The World of the Polar Bear
Praise for the second edition: "Norbert's gift as a photographer is his great curiosity about the natural world. His magic is displayed in photographs that weave light, color and action into a tapestry that tells volumes about life in the Far North."-- National Geographic Magazine "Highly recommended."-- Library Journal (starred review) The polar bear is the largest terrestrial carnivore in the world, uniquely adapted to thrive in the harsh environment of the Far North. In The World of the Polar Bear, renowned nature photographer Norbert Rosing follows the polar bear through each season of the year. This timely third edition has been fully updated and features more than 20 terrific new photo...
Polar Bears
No animal is more symbolic of the Arctic than the Polar Bear. In the short space of 150,000 years, it has undergone behavioural and physiological changes to evolve from a Grizzly Bear into the most specialised predator of the Arctic sea ice. Yet, its survival is now threatened by global warming. Renowned Polar Bear scientist Ian Stirling compresses 40 years of research on these iconic mammals into a new and comprehensive natural history. In accessible language he explains their evolution, life history, behaviour, how they are researched, and the current threat to their very existence. He also explains why the Polar Bears of Hudson Bay have become so important to our understanding of the species, and how Churchill became the "Polar Bear Capital of the World". Maps, tables, graphs and the most diverse collection of Polar Bear photographs ever assembled in a single book provide greater insight into this unique mammal. Underlying it all is a call for immediate action, which can still save this magnificent hunter of the Arctic.
A Little Less Arctic
In Arctic Canada, Hudson Bay is a site of great exploration history, aboriginal culture, and a vast marine wilderness supporting large populations of marine mammals and birds. These include some of the most iconic Arctic animals like beluga, narwhal, bowhead whales, and polar bears. Due to the challenges of conducting field research in this region, some of the mysteries of where these animals move, and how they are able to survive in such seemingly inhospitable, ice-choked habitats are just now being unlocked. For example, are polar bears being replaced by killer whales? This new information could not be more salient, as the Hudson Bay Region is undergoing rapid environmental change due to global warming, as well as increased pressures from industrial development interests. A Little Less Arctic brings together some of the world’s leading Arctic scientists to present the current state of knowledge on the physical and biological characteristics of Hudson Bay.
Polar Bears
These proceedings provide an overview of the ongoing research and management activities on polar bears in the circumpolar arctic. Together with the previous 13 proceedings, they provide an historic record of international efforts in protecting, studying and managing polar bears. With recent documentation of how warmer arctic climate might affect the sea ice habitat of polar bears, the predictions of even warmer climate in the next decades, and documentation of effects on polar bears subpopulations, an evaluation of the red list status of polar bear subpopulations was followed by an increased conservation designation of vulnerable. In the complexity of possible interactions between climate change, local harvest, and in some areas high levels of pollutants, an increased level of international cooperation was advocated.

Arctic Sea Ice Decline
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 180. This volume addresses the rapid decline of Arctic sea ice, placing recent sea ice decline in the context of past observations, climate model simulations and projections, and simple models of the climate sensitivity of sea ice. Highlights of the work presented here include An appraisal of the role played by wind forcing in driving the decline; A reconstruction of Arctic sea ice conditions prior to human observations, based on proxy data from sediments; A modeling approach for assessing the impact of sea ice decline on polar bears, used as input to the U.S. Fish and Wildlife Service's decision ...
