Book Description
After travel through Alaska during the Second World War, in 1947 I went to Barrow with a very lively group of biologists. From their productive research developed the Arctic Research Laboratory. While we examined the rather surpris ingly modest metabolic rates of arctic warmblooded animals in cold, PER SCHO LANDER proposed and then carried out measurements of metabolism of some tropi cal animals in Panama. The differences could be formulated to show the basis of adaptation to arctic cold and to tropical warmth. Imagination and logic were required to formulate the comparison so that it could become a part of science, but the essential measurements were derived from animals and plants in their own arctic and tropical environments. Characteristics that adapt the forms of life to climatic conditions of various environments appear clear in the large dimensions of extremely differing climates. At the time of my arrival in Alaska many of the arctic Eskimos were still largely dependent on natural resources of their immediate and local environment, in which great seasonal changes in temperature and solar radiation appeared as dominant factors. The living environment on which they subsisted was also mar kedly affected by the changes of the seasons, in particular by the change in state of water to ice that terminated summer and by the melting that brought the late transition from winter to summer.

Book Description
Anthony Fiorillo has been exploring the Arctic since 1998. For him, like many others, the Arctic holds the romance of uncharted territory, extreme conditions, and the inevitable epic challenges that arise. For Fiorillo, however, the Arctic also holds the secrets of the history of life on Earth, and its fossils bring him back field season after field season in pursuit of improving human understanding of ancient history. His studies of the rocks and fossils of the Arctic shed light on a world that once was, and provide insight into what might be.

Book Description
Reptiles and birds have highly diverse hearing organs. Data on a huge amount of information concerning all aspects of structural, neurophysiological and anatomical aspects are reviewed as published up to mid-1988: in addition a good deal of yet unpublished data from the author's laboratory are included. The literature on hearing is scattered through a great variety of zoological, medical, psychological, psychoacoustical and bioengineering journals: this book condenses all important findings in one source.

Book Description
Snow has had an astonishing influence on the shape of the land and human history. Ruth Kirk writes perceptively of how animals and people survive in the snow; of glaciers, continental ice sheets, blizzards, and avalanches; and of the awesome hazards of Arctic and Antarctic exploration. She discusses both our battles against snow and our uses of it, showing its importance to agriculture, climate, and the future. Through scientific reports and interviews with experts in various fields--from Antarctic explorers to atmospheric physicists--Kirk surveys the scope of snow's influence.

Book Description
When survival is challenged by the cold, animals react by employing both behavioral and physiological solutions. Depending on the magni tude of the cold stress and the nature of the adjustment, simple avoidance or sophisticated capacity or resistance compensations may be used. Thus, migration, shelter seeking, metabolic and insulative compen sation, torpor, and freezing avoidance and tolerance are successful tac tics used by diverse groups of animals. To understand and appreciate the benefits of these tactics, it is necessary to examine not only the well being of the whole animal but also their basic underlying mechanisms. In ad dition, it is also of fundamental importance to grasp how seasonal cold affects the survivorship and reproductive success of populations when confronted by a general reduction in primary productivity and an elevated energy cost for maintenance (e. g. in endotherms). In this regard, a synthetic overview which integrates aspects of cell biology, biochem istry, physiology, neurobiology, behavior, and population biology should be a fruitful approach in providing a holistic understanding on how animals adapt to cold. The present volume is an attempt to achieve such an overview; its objective is to provide a depth and breadth of coverage that is essential to a full appreciation of animal adaptation to cold. It is the hope of the contributing authors that this book will serve as an effective reference text for all senior undergraduate and graduate students as well as research scientists with an interest in cold physiology.

Book Description
What are the health consequences of a transition from an active 'hunter-gatherer' lifestyle to that of sedentary modern living? In this book, the impact of 'modernization' is assessed in various populations in the circumpolar regions. The hazards of living in polar regions, and the adaptations shown culturally, behaviourally and physically by the indigenous peoples are examined and the effect of changes in habitual activity, diet, and general lifestyle due to more urban living patterns on the body composition, pulmonary function and susceptibility to disease discussed. The implications of this switch are important not only for all those concerned about the survival of indigenous communities around the world, but for all of us living in an increasingly sedentary, urban environment. Anthropologists, physiologists and those interested in population fitness will find this a comprehensive and valuable volume.

Book Description
"Rich detail and vivid anecdotes of adventure....A treasure trove of exotic fact and hard thinking." —New York Times Book Review For millennia, lions, tigers, and their man-eating kin have kept our dark, scary forests dark and scary, and their predatory majesty has been the stuff of folklore. But by the year 2150 big predators may only exist on the other side of glass barriers and chain-link fences. Their gradual disappearance is changing the very nature of our existence. We no longer occupy an intermediate position on the food chain; instead we survey it invulnerably from above—so far above that we are in danger of forgetting that we even belong to an ecosystem. Casting his expert eye over the rapidly diminishing areas of wilderness where predators still reign, the award-winning author of The Song of the Dodo and The Tangled Tree examines the fate of lions in India's Gir forest, of saltwater crocodiles in northern Australia, of brown bears in the mountains of Romania, and of Siberian tigers in the Russian Far East. In the poignant and troublesome ferocity of these embattled creatures, we recognize something primeval deep within us, something in danger of vanishing forever.
