This book offers the most comprehensive and readable review of their biology, ecology, behaviour, and conservation. With gripping photographs by Lynch, a pre-eminent wildlife photographer, and the personal stories of Derocher, this book is as stunning to look at as it is fascinating to read. It weaves together their remarkable experiences with the latest research to tell the amazing story of these Arctic predators, tracing the animals back to their evolutionary roots and looking ahead to the effect of climate change on their world. Through informative and engaging language, Derocher carefully explains the sea ice ecosystem that is essential to the survival of polar bears. He addresses the threat of global warming to the Arctic-home to polar bears for tens of thousands of years-and describes in impressive detail their feeding habits, distribution, den ecology, and reproduction. Lynch's vivid photographs capture all this and more as they chronicle the wide range of polar bear behaviour, from family rituals to ferocious predatory practices.
