Book Description
Sea otters and polar bears are carnivorous marine mammals that still resemble their terrestrial ancestors. Compared with Cetacea (whales and dolphins), Sirenia (dugongs and manatees), and Pinnipedia (seals, sea lions, and walrus), they are less adapted for an aquatic life and the most recently evolved among marine mammals. Sea otters are amphibious but seldom come ashore, and polar bears primarily occur on sea ice or along the shore. When at sea, both species spend most of their time swimming at the surface or making short, shallow dives when foraging or pursuing prey. Indeed, polar bears rarely pursue seals in water. Nevertheless, polar bears are powerful swimmers and will stalk seals from the water. As with many other large carnivores, they are solitary hunters. Although sea otters are gregarious and form aggregations at sea called rafts, they are primarily asocial. Except during mating, the principal interaction among sea otters occurs between a female and offspring during the six-month dependency period. In large carnivores (e.g., wolves and lions) that feed on ungulates, sociality and cooperation are favored because of the need to capture large prey and defend carcasses. Polar bears, which are the largest terrestrial carnivore, are solitary hunters of seals and are neither gregarious nor social. Males and females briefly associate during courtship and mating. During this time, males aggressively compete for females. At other times, males generally avoid each other except for aggregations of males that form while summering on land, and females with cubs avoid males, which are known for infanticide. As with sea otters, the interaction of polar bears outside of mating occurs between a female and her offspring during the 2-3 year dependency period. This interaction is critically important when altricial cubs are born in the winter den. This book provides new insight into the ethology and behavioral ecology of sea otters and polar bears. Each chapter reviews the discoveries of previous studies and integrates recent research using new techniques and technology. The authors also address historic and current anthropogenic challenges for their survival as climate change alters entire marine ecosystems.

Book Description
Do you like polar bears? Do you want polar bears to be around in 50 years? Do you think that climate change is the only major threat to polar bear survival? Do you believe that polar bears are adequately protected today? Would you like to contribute to saving polar bears today and in the future? If your answer to any of those questions is yes, you need to read this book. "This book is an eye-opener and should kick off extensive debates."Dr. Thor S. Larsen, professor emeritus, Member of the IUCN Polar Bear Specialist Group 1968-1985. "In this impassioned book Morten raises very important, provocative questions that are not being addressed by the international environmental groups." Art Wolfe, Award-winning conservation photographer. In this book, the author analyses the current status of the polar bear. And he punctures the myth that polar bears are well protected and managed today. While most people think that global warming is the overhanging threat to polar bear survival, the author documents that it is actually the continuation of an unsustainable hunting pressure that is driving the species towards extinction. Across 228 pages, interspersed with beautiful photographs, Morten Joergensen demonstrates how there are probably fewer polar bears than most authorities claim, how hunting is the greatest manageable threat to the species, how current protection measures are insufficient, how the animal has been commercialized and how lack of courage and honesty is allowing this scenario to continue. The book also contains a long string of realistic and very urgent recommendations for action - to save polar bears before they are gone forever.

Book Description
“A moving story of abandonment, love, and survival against the odds.”—Dr. Jane Goodall The heartbreaking and ultimately hopeful story of an abandoned polar bear cub named Nora and the humans working tirelessly to save her and her species, whose uncertain future in the accelerating climate crisis is closely tied to our own Six days after giving birth, a polar bear named Aurora got up and walked away from her den at the Columbus Zoo, leaving her tiny squealing cub to fend for herself. Hours later, Aurora still hadn’t returned. The cub was furless and blind, and with her temperature dropping dangerously, the zookeepers entrusted with her care felt they had no choice: They would have to raise one of the most dangerous predators in the world by hand. Over the next few weeks, a group of veterinarians and zookeepers worked around the clock to save the cub, whom they called Nora. Humans rarely get as close to a polar bear as Nora’s keepers got to their fuzzy charge. But the two species have long been intertwined. Three decades before Nora’s birth, her father, Nanuq, was orphaned when an Inupiat hunter killed his mother, leaving Nanuq to be sent to a zoo. That hunter, Gene Agnaboogok, now faces some of the same threats as the wild bears near his Alaskan village of Wales, on the westernmost tip of the North American continent. As sea ice diminishes and temperatures creep up year after year, Agnaboogok and the polar bears—and everyone and everything else living in the far north—are being forced to adapt. Not all of them will succeed. Sweeping and tender, The Loneliest Polar Bear explores the fraught relationship humans have with the natural world, the exploitative and sinister causes of the environmental mess we find ourselves in, and how the fate of polar bears is not theirs alone.

Book Description
Prime Arctic predator and nomad of the sea ice and tundra, the polar bear endures as a source of wonder, terror, and fascination. Humans have seen it as spirit guide and fanged enemy, as trade good and moral metaphor, as food source and symbol of ecological crisis. Eight thousand years of artifacts attest to its charisma, and to the fraught relationships between our two species. In the White Bear, we acknowledge the magic of wildness: it is both genuinely itself and a screen for our imagination. Ice Bear traces and illuminates this intertwined history. From Inuit shamans to Jean Harlow lounging on a bearskin rug, from the cubs trained to pull sleds toward the North Pole to cuddly superstar Knut, it all comes to life in these pages. With meticulous research and more than 160 illustrations, the author brings into focus this powerful and elusive animal. Doing so, he delves into the stories we tell about Nature—and about ourselves—hoping for a future in which such tales still matter.

Book Description
- Spectacular photographs of the polar bear: the largest carnivore to walk the earth today - Captures polar bears at play, hunting, sleeping, fighting and feeding - Follows the bears across the Arctic, from settlements to forests, pack-ice to tundra ...this is a glorious and luxurious book, surely one of the finest collections of polar bear photography published in recent times" - BBC Wildlife A 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 bears' innate curiosity shines through, as they peer through windows and rear up on their hind legs to study the camera. As well as trekking across miles of dazzling snow, they forage in forests and towns - leading to a striking series of photographs that document the relationship between bear, man and environment. Accompanying these images are a series of essays, poems and even a quiz, from the minds of Michel Rawicki and his contributors: Hubert Reeves, astrophysicist, and Remy Marion, author of several books about the polar regions. They explain the challenges encountered by polar bears in the modern age, and explore the future of a species threatened by climate change and pollution.
