"Animal Life at Low Temperature" is concerned with the behavioural, physiological and biochemical responses of animals to cold, including details of anatomical adaptations. It draws together the results of recent research into topics such as hibernation, antifreezes in fish, the evolution of warm-bloodedness and the importance of cold to evolution and extinction. The book opens with a chapter devoted to the basic concepts of the chemistry and physics of low temperature, the biochemistry of heat production and the categorization of animals such as ectotherms and endotherms. After describing current and past temperate and arctic environments the chapters go on to describe the behaviour, anatomy and physiology of animals exposed to cold conditions. Cryobiology is dealt with in detail including the functions of fish antifreezes, thermal hysteresis proteins and cryoprotective agents. There is a large section devoted to humans, essentially tropical apes that have successfully colonized cold regions of the world by behavioural and technological means. Finally the author addresses low temperature as an agent of evolutionary change including mutation and recombination rates. Supported by numerous assimilable examples, it should provide a sound grounding for both undergraduates and research workers.

This new book provides a highly readable account of the ways in which animals of all types cope with a cold environment - Nature; a readable, interesting and useful guide.... thoroughly referenced, well illustrated... the breadth of coverage in this section is appealing. Part Two describing Behaviour, Anatomy and Physiology was thorough and contains a well written section on the anatomy and physiology of endotherms. I was particularly impressed with the extensive section covering sleep, torpor and hibernation... the book as a whole is one which thermal physiologists and others interested in the field will find of great general utility - American Zoological; ...can be recommended to any biologist interested in animal life at low temperature, adn especially to those interested in animal behavior - Ethology

Part 1 Introductory material: basic concepts - temperature, water and low temperature, colligative properties of aqueous solutions, categories of body temperature control, zone of neutrality, critical temperatures, Newton's Law of Cooling, thermal conductance, windchill, cold acclimatization and adaptation, heat production; the cold environment - present conditions, palaeoclimatology, climatic zones, high latitude microhabitats. Part 2 Behaviour, anatomy and physiology: behavioural responses to low temperature - movement, basking, gregariousness, shelter; anatomy and physiology of endotherms - shape, size and climate, structural insulation (fur, fat and feathers), vascular arrangements to minimize heat loss, physiological insulation, thermogenesis; sleep, torpor and hibernation - in ectotherms, in endotherms, supercooled hibernation in endotherms, hibernation in bears. Part 3 Life at temperatures below 0 C: subzero survival in terrestrial animals - survival of insects and other terrestrial arthropods, freezing-tolerance in terrestrial vertebrates; subzero temperatures and marine ectotherms - supercooling in deep-water fish, heightened plasma osmolarity in cold-water fish, antifreezes in high-latitude fish, eggs of the capelin, freezing in intertidal invertebrates, freezing avoidance by intertidal invertebrates. Part 4: Man and cold - human morphology and cold, physiological/metabolic adaptations and responses, damage by cold, clothing, shelter, fire, cold and human diet, medical hypothermia, cold technology. Part 5 Cold and evolution: evolution and low temperature - general considerations, cold and the evolution of endothermy, cold and extinction.
