Book Description
To humans, cold has a distinctly positive quality. 'Frostbite', 'a nip in the air', 'biting cold', all express the concept of cold as an entity which attacks the body, numbing and damaging it in the process. Probably the richness of descriptive English in this area stems from the early experiences of a group of essentially tropical apes, making their living on a cold and windswept island group half way between the Equator and the Arctic. During a scientific education we soon learn that there is no such thing as cold, only an absence of heat. Cold does not invade us; heat simply deserts. Later still we come to appreciate that temperature is a reflection of kinetic energy, and that the quantity of kinetic energy in a system is determined by the speed of molecular movement. Despite this realization, it is difficult to abandon the sensible prejudices of palaeolithic Homo sapiens shivering in his huts and caves. For example; appreciating that a polar bear is probably as comfortable when swimming from ice floe to ice floe as we are when swimming in the summer Mediterranean is not easy; understanding the thermal sensa tions of a 'cold-blooded' earthworm virtually impossible. We must always be wary of an anthropocentric attitude when considering the effects of cold on other species.

Book Description
Temperature is one facet in the mosaic of physical and biotic factors that describes the niche of an animal. Ofthe physical factors it is ecologically the most important. for it is a factor that is all-pervasive and one that. in most environments. lacks spatial or temporal constancy. Evolution has produced a wide variety of adaptive strategies and tactics to exploit or deal with this variable environmental factor. The ease with which temperature can be measured. and controlled experimentally. together with its widespread influence on the affairs of animals. has understandably led to a large. dispersed literature. In spite of this no recent book provides a comprehensive treatment of the biology of animals in relation to temperature. Our intention in writing this book was to fill that gap. We hope we have provided a modern statement with a critical synthesis of this diverse field. which will be suitable and stimulating for both advanced undergraduate and post graduate students of biology. This book is emphatically not intended as a monographical review. as thermal biology is such a diverse. developed discipline that it could not be encompassed within the confines of a book of this size.

Book Description
The new and updated edition of this accessible text provides a comprehensive overview of the comparative physiology of animals within an environmental context. Includes two brand new chapters on Nerves and Muscles and the Endocrine System. Discusses both comparative systems physiology and environmental physiology. Analyses and integrates problems and adaptations for each kind of environment: marine, seashore and estuary, freshwater, terrestrial and parasitic. Examines mechanisms and responses beyond physiology. Applies an evolutionary perspective to the analysis of environmental adaptation. Provides modern molecular biology insights into the mechanistic basis of adaptation, and takes the level of analysis beyond the cell to the membrane, enzyme and gene. Incorporates more varied material from a wide range of animal types, with less of a focus purely on terrestrial reptiles, birds and mammals and rather more about the spectacularly successful strategies of invertebrates.

Book Description
If you think that watching all the nature programs on television qualifies you as an expert on the subject, think again! Do you really know what makes animals tick? Here are the answers, portrayed in stunning, awe-inspiring action sequences and explained in fascinating, in-depth prose. Thematically arranged by behavior trait, Animal Life explores and explains every aspect of animal behavior, including courtship rituals and sex lives, family relationships and defense mechanisms, hunting techniques and feeding habits. Side panels explore some of the field research on animal behavior and explain important conservation issues. The introductory chapters on the Animal Kingdom and on animal anatomy help explain how different animals have evolved and adapted to their environments, adaptations that may be relevant to particular behaviors. Destined to be the ultimate authority on animal behavior, this book also looks at key behavioral concepts such as how animals learn to behave and the role of instinct in the learning process.

Book Description
How do dolphins catch fish in murky water? Why do moths drink from puddles? How do birds' eggs breathe? How do animals work? In this revised and updated edition of the acclaimed text Animal Physiology, the answers are revealed. In clear and stimulating style, Knut Schmidt-Nielsen introduces and develops the fundamental principles of animal physiology according to major environmental features - oxygen, food and energy, temperature, and water. The structure of the book is unchanged from the previous edition, but every chapter has been updated to take into account recent developments, with numerous new references and figures. Animal Physiology is suitable as a text for undergraduate and beginning graduate courses in physiology. As with previous editions, students, teachers as well as researchers will find this book a valuable and enjoyable companion to course work and research.
