Book Description
Animals and Environmental Fitness: Physiological and Biochemical Aspects of Adaptation and Ecology, Volume 2 contains the proceedings of the First Conference of the European Society for Comparative Physiology and Biochemistry held in Liège, Belgium, on August 27-31, 1979. The papers explore the physiology and biochemistry of animal adaptation and ecology and cover topics ranging from amino acid transport and metabolism during osmotic shock to the role of organic compounds in osmoregulation in plants and animals. This volume is comprised of 89 chapters and begins with an analysis of the transport and metabolism of amino acids under osmotic stress, followed by a discussion on cell volume regulation in isolated heart ventricles from the flounder, Platichthys flesus, perfused with anisosmotic media. Subsequent chapters focus on the effects of cholinergic drugs on the osmotic fragility of erythrocytes; strategies of osmoregulation in the fiddler crab Uca pugilator; ionic regulation in the African catfish Clarias mossambicus in water and air; and environmental and endocrine factors controlling osmotic water fluxes in gills of Sarotherodon (tilapia) mossambicus. The effect of seawater adaptation on the phosphatidyl-choline metabolism in the eel is also considered, along with evaporative water loss in anuran amphibians. This book will be of value to zoologists, physiologists, biologists, and biochemists.

Book Description
Animals and Environmental Fitness, Volume 1: Invited Lectures is a collection of papers that tackles ecological concerns. The materials of the book are organized according the main issue of their contents. The text first tackles the chemical factors of the environment, such as water and oxygen availability, ecomones, and pollutants. The other half of the book encompasses the physical factors of the environment that include light, pressure, and temperature. The text will be of great use to scientists who study the interaction between flora, fauna, and the total environment.

Book Description
This volume constitutes a series of invited chapters based on presentations given at an International Conference on the Sensory Biology of Aquatic Animals held June 24-28, 1985 at the Mote Marine Laboratory in Sarasota, Florida. The immediate purpose of the conference was to spark an exchange of ideas, concepts, and techniques among investigators concerned with the different sensory modalities employed by a wide variety of animal species in extracting information from the aquatic environment. By necessity, most investigators of sensory biology are specialists in one sensory system: different stimulus modalities require different methods of stimulus control and, generally, different animal models. Yet, it is clear that all sensory systems have principles in common, such as stimulus filtering by peripheral structures, tuning of receptor cells, signal-to-noise ratios, adaption and disadaptation, and effective dynamic range. Other features, such as hormonal and efferent neural control, circadian reorganization, and receptor recycling are known in some and not in other senses. The conference afforded an increased awareness of new discoveries in other sensory systems that has effectively inspired a fresh look by the various participants at their own area of specialization to see whether or not similar principles apply. This inspiration was found not only in theoretical issues, but equally in techniques and methods of approach. The myopy of sensory specialization was broken in one unexpected way by showing limitations of individual sense organs and their integration within each organism. For instance, studying vision, one generally chooses a visual animal as a model.

Book Description
Deserts, whether hot or cold, are considered to be one of the most difficult environments for living systems, lacking the essential free water which ac counts for approximately 60-70% of their body mass and more than 98% of their constituent atoms {Macfarlane 1978}. Amongst vertebrates, reptiles are usually thought of as the animals most adapted or suited to such environments because of their diurnal habit, based on a need for external heat, and their ability to survive far from obvious sources of water. This impression is rein forced when one examines the composition of vertebrate faunae characteristic of deserts and arid zones: reptiles predominate and they are often the only vertebrates to be found in hyper-arid areas, such as some parts of the Sahara {Monod 1973}. I recently had occasion to examine this assumption carefully, however, and was led inexorably to the conclusion that reptiles represent a particularly successful desert group, not because of their evolution of superior adaptations, but because of their possession of a basic suite of behavioural and physiologi cal characteristics that suit them uniquely to this very resource-limited environment {Bradshaw 1986a}. These fundamental reptilian characteristics are: 1. their low rates of metabolism, compared with birds and mammals, which result in extremely low rates of resource utilisation and lead to considerable economy in the handling of water 2.

Book Description
During the last 20 years two groups of investigators have concerned themselves with the problem of acid-base regulation at various body temperatures. Each group, in professional isolation, pursued a separate path. Surgeons and anesthe tists developed techniques and tools for hypothermic cardio-pulmonary by-pass operations and based their rationale for acid-base management on in vitro models of blood behavior. Physiologists and biochemists, on the other hand, endeavored to understand acid-base regulation in living organisms naturally subjected to changes in body temperature. Only in the last decade has there been an increasing awareness that each group could benefit from the other's experiences. With this goal in mind members of both groups were invited to present their views and observations in the hope of arriving at a better understanding of acid-base management during hypothermia and gaining a greater insight into the factors which control acid-base regulation during normothermia. This led to the presen tation of the present volume with the aim of providing the clinician with a survey of present theories and the resulting strategies for management of the hypother mic patient. Acknowledgment The editors express their great appreciation to Miss Augusta Dustan for her dedicated effort in the preparation and editing of the manuscripts. Contributors Heinz Becker, M. D.

Book Description
The purpose of NEURAL MECHANISM in TASTE is to emphasize physiological principles and reveal new insights of this most recent research. This book is aimed to reach scientists within the broad area of neurophysiology as well as those in other disciplines who have interests in sensory mechanisms. The focus is on two major themes--peripheral mechanisms and neural processing at the central level. Every chapter is written by an expert on the subject matter, including definitive updates on the status of each topic. This work is not only useful to researchers in taste, but also to basic and applied scientists in related fields (such as food technology), doctoral and postdoctoral students.
