Polar bears are amazing creatures for many reasons. Their white coats and expressive faces make them a favorite of both children and adults. Ingenious hunters, they are the world’s largest land predator. They will also swim hundreds of miles to reach their favorite hunting grounds. The bears do all of this in one of the most difficult environments in the world: the Arctic. Unfortunately, the bears’ life may be getting even harder because of humans. Find out what is happening to the polar bears of the Hudson Bay, and what you can do to help.

A Little Less Arctic by Steven H. Ferguson,Lisa L. Loseto,Mark L. Mallory Pdf
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.

From bestselling author James Raffan comes an enlightening and original story about a polar bear’s precarious existence in the changing Arctic, reminiscent of John Vaillant’s The Golden Spruce. Nanurjuk, “the bear-spirited one,” is hunting for seals on Hudson Bay, where ice never lasts more than one season. For her and her young, everything is in flux. From the top of the world, Hudson Bay looks like an enormous paw print on the torso of the continent, and through a vast network of lakes and rivers, this bay connects to oceans across the globe. Here, at the heart of everything, walks Nanurjuk, or Nanu, one polar bear among the six thousand that traverse the 1.23 million square kilometers of ice and snow covering the bay. For millennia, Nanu’s ancestors have roamed this great expanse, living, evolving, and surviving alongside human beings in one of the most challenging and unforgiving habitats on earth. But that world is changing. In the Arctic’s lands and waters, oil has been extracted—and spilled. As global temperatures have risen, the sea ice that Nanu and her young need to hunt seal and fish has melted, forcing them to wait on land where the delicate balance between them and their two-legged neighbors has now shifted. This is the icescape that author and geographer James Raffan invites us to inhabit in Ice Walker. In precise and provocative prose, he brings readers inside Nanu’s world as she treks uncertainly around the heart of Hudson Bay, searching for nourishment for the children that grow inside her. She stops at nothing to protect her cubs from the dangers she can see—other bears, wolves, whales, human beings—and those she cannot. By focusing his lens on this bear family, Raffan closes the gap between humans and bears, showing us how, like the water of the Hudson Bay, our existence—and our future—is tied to Nanu’s. He asks us to consider what might be done about this fragile world before it is gone for good. Masterful, vivid, and haunting, Ice Walker is an utterly unique piece of creative nonfiction and a deeply affecting call to action.
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.

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.
This title presents a collection of photographs by acclaimed 'polar bear photographer' Steven Kazlowski. Featuring mostly never-before-published images, this simple yet evocative book explores the polar bear's Arctic home and life cycle.
