Nutrition spans a wide range of mechanisms from acquisition of food to digestion, absorption and retention of energy substrates, water and other nutrients. Nutritional principles have been applied to improving individual health, athletic performance and longevity of humans and of their companion animals, and to maximizing agricultural efficiency by manipulating reproduction or growth of tissues such as muscle, hair or milk in livestock. Comparative nutrition borrows from these tra- tional approaches by applying similar techniques to studies of ecology and physiology of wildlife. Comparative approaches to nutrition integrate several levels of organization because the acquisition and flow of energy and nutrients connect individuals to populations, populations to communities, and communities to ecosystems. Integrative Wildlife Nutrition connects behavioral, morphological and biochemical traits of animals to the life history of species and thus the dynamics of populations. An integrated approach to nutrition provides a practical framework for understanding the interactions between food resources and wildlife popu- tions and for managing the harvest of abundant species and the conservation of threatened populations. This book is for students and professionals in animal physiology and ecology, conservation biology and wildlife management. It is based on our lectures, dem- strations and practical classes taught in the USA, Canada and Australia over the last three decades. Instructors can use Integrative Wildlife Nutrition as a text in wildlife and conservation biology programs, and as a reference source for related courses in wildlife ecology.
Rodents are the predominant experimental animals found in life-sciences research laboratories. The body temperature of a rodent is markedly affected by surgical, chemical or environmental manipulation. Because temperature regulation is controlled essentially by a 'holistic' regulatory system, meaning that its responses affect the activities of all other psychological and behavioural processes, it is clear that researchers working with rodents must be familiar with thermoregulatory physiology. With the help of extensive data tables and figures, this book explains the key facets of rodent thermal physiology, including neurological control and gender and intraspecies variations. There is a novel chapter on the effects of trauma, toxic chemicals and other factors. The book should therefore find use in government, academic or industrial laboratories whose researchers are working with rodents.
In this unique book, Sir Donald Harrison draws on his wide-ranging experience as a surgeon and comparative anatomist to produce an authoritative and detailed account of the anatomy and physiology of the mammalian larynx. His investigation of the larynx has involved the study of over 1400 specimens of mammalian larynges from around the world, as well as using data from his own clinical experiences. The comparative morphology of the larynx is discussed from a developmental and functional perspective and the involvement of the larynx in respiration, locomotion and vocalisation is highlighted. Throughout the book the relationship of structure to function is drawn out and the clinical relevance of features of the human larynx is emphasised. This book will be an invaluable reference for all researchers and clinicians involved in laryngology as well as for anatomists, zoologists and anaesthesiologists.
During the last two decades, major advances have been made in mammalian genetics. New methods in molecular and cytogenetics, and in biotechnology have been developed. Many of these have been applied to investigating the genetics of sheep and to improving the production of wool, meat and milk. This book is a comprehensive reference work on sheep genetics. All relevant topics have been included, from fundamental genetic structure to the genetics of various production and other traits, to transgenic sheep and genetic conservation. Chapters have been specially commissioned for the volume and written by internationally recognized experts from Europe, USA, Australia and New Zealand. The book will be invaluable to advanced students and research workers in animal genetics, breeding and biotechnology.
Comparative Physiology: Primitive Mammals attempts to dispel the widely held notion that 'primitive' animals are less advanced or less complex than the 'non-primitive'. The term 'primitive', or more accurately 'conservative', refers to the fact that these animals have retained many of the characteristics of their evolutionary ancestors. Because they have been able to adapt to a variety of environmental conditions, these so-called primitive animals should be considered highly successful evolutionary solutions. The papers contained in this volume are the result of the Fourth International Conference on Comparative Physiology held at Crans-sur-Sierre in 1978. The conference, which was sponsored by the Interunion Commission on Comparative Physiology representing the International Unions of Biological Sciences, Physiological Sciences, and Pure and Applied Biophysics, brought together scientists from various fields to discuss the widely scattered information on primitive mammals from the perspective of comparative physiology.
In the natural world colour is obvious and its importance in advertising the presence of flowers to pollinators and in camouflage is well known. In most cases the property of colour is due to the presence in the tissues of natural pigments. But these pigments are of much greater importance than merely to give colour, e.g. the fundamental light-harvesting molecules of photosynthesis, the light-detecting molecules of vision and haemoglobin in the blood. This book describes the structures and properties of the main groups of natural pigments, their distribution in Nature, their biosynthesis and functions and their associated chemistry and biology. Industrial applications, and medical significance and uses, of certain groups of pigments are outlined and some ecological aspects of colour and pigmentation are touched upon. The book was written as a textbook for advanced undergraduates and graduate students and concentrates on the main features of each class of pigments and on general principles.
The analysis of the circulation of the blood is one of the most important areas of fluid mechanics research, with far-reaching medical and physiological implications.
The extraordinary ability of dolphins to echolocate has fascinated scientists and the public since its discovery in the late 1950's. This is the first book to summarize modern research in this area, and presents a broad synthesis of this very interdisciplinary subject. The author is an internationally-recognized expert on dolphin sonar and is thus in a unique position to bring together research on the physiological, mathematical and engineering aspects of the subject. Of interest to auditory researchers, electrical engineers, acoustical physicists, and mammalian physiologists.
Aquatic organisms swim in a variety of ways, from jet propulsion to ciliary action: they swim at a wide range of speeds and span a vast size range, from bacteria to protists, to the largest whales. One of the most fascinating aspects of aquatic locomotion is the remarkable sets of adaptations that have been evolved for different purposes. This volume brings together research on a wide range of swimming organisms, with an emphasis on the biomechanics, physiology and hydrodynamics of swimming in or on water. Several chapters deal with different aspects of fish swimming, from the use of different 'gaits' to the operation of the locomotor muscles. All chapters are by recognized authorities in their different fields, and all are accessible to biologists interested in aquatic locomotion.
Amphibians are the extant descendants of the first vertebrate class to successfully colonize terrestrial environments; hence they occupy a unique position between fish and reptiles. Amphibian skin provides essentially no resistance to evaporative water loss, and consequently daily water turnover rates are an order of magnitude greater than in other terrestrial vertebrate groups. This has led to a suite of physiological, morphological and behavioural adaptations that have allowed a successful terrestrial existence in spite of this apparently spendthrift water retention strategy. Ecological and Environmental Physiology of Amphibians provides a synthesis of current research on the comparative physiology of amphibians with a particular emphasis on water balance. It adopts a strong environmental perspective and includes a wealth of information on ecology, phylogeny and development. As with other books in the Ecological and Environmental Physiology Series, the emphasis in this book is on the unique physiological characteristics of the amphibians, although the latest experimental techniques and future research directions are also considered. This accessible text is suitable for both graduate students and researchers in the fields of amphibian comparative physiology and physiological ecology, including specialist courses in amphibian ecology. It will also be of value and use to the many professional herpetologists requiring a concise overview of the topic.
This book provides a comprehensive account of the proteins involved in blood coagulation, fibrinolysis and the complement system. A major section of the book is devoted to each of these three systems, with separate chapters dealing in detail with structural aspects and different functional processes. Topics covered in the blood coagulation section include the activation of factors IX and X and prothrombin, and the formation and stabilisation of fibrin. The fibrinolysis section includes the activation of plasminogen, the degradation of fibrin and the regulation of fibrinolysis. The complement system itself is covered in chapters dealing with classical activation, alternative activation, the lytic complex and the regulatory processes involved. In addition, one section deals with special topics, including the kinin system, signal peptides, haemostasis, and the evolution of protein structure. This volume will be of use to researchers and advanced students in the fields of haematology, immunology and clinical chemistry.
The aim of this book is to provide experimental protocols covering many aspects of glycobiology, glycotechnology, and chemistry: biochemistry, molecular and cellular biology, genetics, physiology, and medicine. The protocols are all self-contained descriptions of the equipment and reagents needed, followed by details of the experimental procedure. In the post-genomic era, glycobiology is coming of age because more than half of proteins are glycosylated and the importance of sugar chains in various fields of life science research cannot be disregarded. Many scientists had not entered this area because glycobiology and glycoscience used to be considered difficult fields. This book, therefore, is presented much like a cookbook which can help scientists in fields other than glycobiology and glycoscience carry out research more easily.
In this monograph the authors have emphasized a number of important concepts in mammalian kidney development. Emphasis has been put on methodology so that the reader can understand how certain results or conclusions were reached and what the optimal methods for reliable results to be obtained are. In addition, as well as descriptions of the morphology there is information on the genetic basis of the structural development. In addition much attention has been paid to how nephron number may be altered by changes in the environment of the developing kidney and to the consequences for the remaining nephron gene expression and kidney function when total nephron number is altered. The consequences for the health of the adult, upon the formation of an adult kidney with altered nephron number and (potentially) gene expression, can be quite serious. The epigenetic mechanisms by which such changes can occur are introduced as a very fertile field for future investigation.
This book gives a concise account of the physiology and form of the fish circulatory system. The emphasis is primarily on function, but details of structure have been included. Following a revision of ideas on hemodynamics, attention is focused on the heart as the primary pump in the fish circulatory system. The fine structure and the electrical and ionic events of cardiac myocytes are described and the major events of the cardiac cycle are outlined. The structure of the peripheral vessels then follow and attention is devoted to the circulation in certain special areas such as the gills, the renal portal system, and the secondary blood system. There are also chapters devoted to the blood and the hemopoetic tissues and an account is given of the different types of retial systems that concentrate oxygen or heat in various parts of the body. Following a description of the autonomic nervous system, the circulatory responses to exercise and hypoxia are described. The book concludes with a discussion on the circulation of hagfish and how it illuminates our understanding of the functional and structural evolution of the circulatory system.
The maintenance of a stable acid-base status within biological tissue is a fundamental homeostatic process in all organisms, necessary to preserve the metabolic function of proteins and other macromolecules. The study of acid-base regulation has advanced enormously over recent decades due to the development of increasingly accurate and sensitive techniques for measuring acid-base variables. This volume brings together contributions from leading comparative physiologists working on factors affecting the acid-base status of the internal fluids of animals and plants. The result is a broad-ranging, authoritative and accessible review of the most recent and exciting discoveries in this area, together with a critical look at current techniques and tools.
Environmental temperature varies in time and space on timescales ranging from a few hours to long-term climate change. Organisms are therefore continually challenged to regulate and maintain functional capacities as their thermal environment changes. This volume brings together many of the leading workers in thermal biology, with backgrounds spanning the disciplines of molecular biology, cell biology, physiology, zoology, ecology and evolutionary biology, to discuss the responses of a wide range of species to temperature change at all scales of organization, ranging through the molecular, cellular, organismal, population and ecosystem levels. The volume provides an important and comprehensive contribution to the study of temperature adaptation, which, given the concern about global climate change, will provide much to interest a wide range of biologists.
From a human viewpoint, the cold waters of deep sea and polar marine regions present an inhospitable and harsh environment for life. The study of organisms which have exploited this seemingly hostile ecological niche has revealed intriguing physiological adaptations. This volume summarizes the information on the adaptations exhibited by representatives of the main groups of polar animals, including marine invertebrates, fish, mammals and birds, at scales ranging from the whole organism through to the underlying molecular adaptational mechanisms. Unique in its breadth of coverage, this volume will provide an important resource for all those concerned specifically with how animals have adapted to life in extreme conditions, as well as being of general interest to all marine biologists.
The cestodes, or tapeworms, are a group of parasitic worms many species of which cause serious, often fatal, diseases in man and domestic animals throughout the world. This book is an updated and expanded version of Professor Smyth's The Physiology of Cestodes (1969). The text has now been entirely rewritten, taking into account advances in investigative techniques such as immunocytochemistry, in vitro culture and scanning electron microscopy, which have immensely increased our understanding of these organisms. The biochemical coverage now includes the spectacular advances in molecular biology that have occured. The book also shows how cestodes are increasingly being recognized as valuable models for investigating fundamental biological phenomena such as membrane transport and asexual/sexual differentiation. Students of medicine, veterinary medicine, parasitology and zoology will find this book invaluable. Its high research content and extensive references also make it an essential reference book for researchers in these fields.
Bird flight has always intrigued mankind. This book provides an up
to date account of our existing knowledge on the subject, as well
as offering new insights and challenging some established views.
Primate dentitions vary widely both between genera and between species within a genus. This book is a comparative dental anatomy of the teeth of living non-human primates that brings together information from many disciplines to present the most useful and comprehensive database possible in one consolidated text. The core of the book consists of comparative morphological and metrical descriptions with analyses, reference tables and illustrations of the permanent dentitions of 85 living primate species to establish a baseline for future investigations. The book also includes information on dental microstructure and its importance in understanding taxonomic relationships between species, data on deciduous dentitions, prenatal dental development and ontogenetic processes, and material to aid age estimation and life history studies. Primate Dentition will be an important reference work for researchers in primatology, dental and physical anthropology, comparative anatomy and dentistry as well as vertebrate paleontology and veterinary science.
Respiration represents the major area of ignorance in our understanding of the global carbon cycle. In spite of its obvious ecological and biogeochemical importance, most oceanographic and limnological textbooks invariably deal with respiration only superficially and as an extension of production and other processes. The objective of this book is to fill this gap and to provide the first comprehensive review of respiration in the major aquatic systems of the biosphere. The introductory chapters review the general importance of respiration in aquatic systems, and deal with respiration within four key biological components of aquatic systems: bacteria, algae, heterotrophic protists, and zooplankton. The aim of this first part is to provide the backbone for the analysis and interpretation of ecosystem-level respiration in a variety of aquatic environments. The central chapters of the book review respiration in major aquatic ecosystems including freshwater wetlands, lakes and rivers, estuaries, coastal and open ocean and pelagic ecosystems, as well as respiration in suboxic environments. For each major ecosystem, the corresponding chapter provides a synthesis of methods used to assess respiration, outlines the existing information and data on respiration, discusses its regulation and link to biotic and abiotic factors, and finally provides regional and global estimates of the magnitude of respiration. The final chapter provides a general synthesis of the information and data provided in the different sections, and further attempts to place aquatic respiration within the context of the global carbon budget.
Wild animals survive in a variety of complex environments; they are exposed to predictable and unpredictable changes in their particular environment on a daily or seasonal basis. However, we live in a time when almost all natural environments are undergoing relatively rapid change, and many of these changes, such as the pollution of air and water, removal of natural food sources, environment fragmentation, and climate change, are the result of human activity. Animal Physiology: an environmental perspective shows how an understanding of the physiology of animals in their natural habitats helps us to understand not only how and why animals evolved the way they did, but how we can act to protect at least some of them from the extreme effects of the changes affecting their environments. Part One sets the foundation for the topics covered in the remainder of the book by introducing a range of fundamental processes that are essential to life. It considers the diversity of habitats on Earth in which animals live, and examines animal groups and their evolutionary relationships. It then explores the different feeding strategies used by animals to obtain the energy they require to carry out all the essential functions of life, and how animals convert the chemical energy in food molecules into the energy they need to power all body functions. Finally, it explores the general properties of animal cells, and how animals maintain a suitable internal environment in which their cells are protected from external influences. We then examine those fundamental principles governing the main exchanges between the cells within animals, and between an animal and its environment. Parts two to four of the book explore how different organ systems - respiratory and circulatory systems, excretory organs and endocrine systems - enable animals to interact with their environment, and how environmental temperature profoundly affects the physiology of animals. Part five considers how the sensory and nervous systems provide animals with information on their internal as well as their external environment, and how they, together with the endocrine system, are involved in the control and co-ordination of muscles, reproduction, salt and water balance, and the cardio-respiratory systems.

Examples are collected from a wide range of vertebrates living in deserts, cold climates and oceans. The book is an introduction to ecophysiology for advanced students, as well as researchers in ecology, biodiversity and conservation.
Comprising well over half of all known animal species, insects are the most successful organisms on the planet. Indeed, it is no exaggeration to say that one cannot study agriculture, biology, and the environment, without a basic understanding of entomology. Furthermore, insects are indispensable to advances in molecular biology and genetics, and their ongoing decline in many parts of the world has stimulated much research in the crucial roles they play in global ecosystems. However, the sheer diversity of insects can be a challenge to every newcomer to entomology. Most entomology textbooks tend to focus on insect biology, leaving readers with only a superficial idea of insect diversity and evolution, while others delve into too much detail that will deter the novice. In contrast, Essential Entomology has a clear taxonomic structure that provides readers with the necessary framework to understand the diversity, life history, and taxonomy of insects in a new light. This fully revised edition provides the most up-to-date guide to insects and includes all the major developments in molecular biology and palaeontology of the last 20 years. This textbook is an essential read for undergraduate and graduate students taking courses in entomology, agriculture, and forestry. It will also appeal to a broad academic audience of ecologists, conservationists, natural resource managers, as well as to the far more numerous general readers who are interested in wildlife, nature, and the environment. With these diverse audiences in mind, the straightforward and accessible style of the first edition has been maintained, technical jargon has been kept to a minimum, and sufficient background information is provided to enable the reader to follow the text with ease.
Insects are the most ecologically important multicellular heterotrophs in terrestrial systems. They play critical roles in ecological food webs, remain devastating agricultural and medical pests, and represent the most diverse group of eukaryotes in terms of species numbers. Their dominant role among terrestrial heterotrophs arises from a number of key physiological traits, and in particular by the developmental and evolutionary plasticity of these traits. Ecological and Environmental Physiology of Insects presents a current and comprehensive overview of how the key physiological traits of insects respond to environmental variation. It forges conceptual links from molecular biology through organismal function to population and community ecology. As with other books in the Series, the emphasis is on the unique physiological characteristics of the insects, but with applications to questions of broad relevance in physiological ecology. As an aid to new researchers on insects, it also includes introductory chapters on the basics and techniques of insect physiology ecology. |
