Pheromones and other kinds of chemical communication underlie the behavior of all animals. Building on the strengths of the first edition, widely recognized as the leading text in the subject, this is a comprehensive overview of how pheromones work. Extensively revised and expanded to cover advances made over the last ten years, the book offers a thorough exploration of the evolutionary and behavioral contexts of chemical communication along with a detailed introduction to the molecular and neural basis of signal perception through olfaction. At a time of ever increasing specialization, Wyatt offers a unique synthesis, integrating examples across the animal kingdom. A final chapter critically considers human pheromones and the importance of olfaction to human biology. Its breadth of coverage and readability make the book an unrivaled resource for students and researchers in a range of fields from chemistry, genetics, genomics, molecular biology and neuroscience to ecology, evolution and behavior.

In the thirty years since its discovery by Terje Lomo and Tim Bliss, Long Term Potentiation (LTP) has become one of the most extensively studied topics in contemporary neuroscience. In LTP the strength of synapses between neurons is potentiated following brief but intense activation. LTP is thought to play a central role in learning and memory, though the exact nature of its role is less clear. In spite of years of research, there are many questions about LTP regarding its functional relevance that remain unanswered - for example, is it a model of memory formation, or is the actual neural mechanism used by the brain to store information? This volume presents a state of the art account of LTP. It begins with lively accounts, by the scientists most closely involved, of the discovery of LTP and of the experiments that established its basic properties and induction mechanisms. Later contributions contain reviews and new research that cover the range of molecular, cellular, physiological and behavioural approaches to the study of LTP. Provocative, accessible, and authoritative, this book makes it clear why LTP continues in equal measure to puzzle and beguile neuroscientists today. Advance praise for Long Term Potentiation: "This book provides a definitive overview of the development of ideas about synaptic plasticity and about the wide range of current research in this fascinating field." Colin Blakemore, University of Oxford

Cold is the single most important enemy of life, and this book, first published in 1985, discusses the responses of living organisms to low temperatures. Subfreezing temperatures in particular affect the properties of water, which is essential to life, and the book describes the physics and chemistry of water in the context of physiology. Injury from cooling and the way in which organisms respond and survive, as well as the mechanism of cold hardening in micro-organisms, insects and plants are discussed. The laboratory exploitation of low temperatures to preserve life and to protect labile materials against freeze damage is also considered.

In the last decade, research on the previously dormant field of camouflage has advanced rapidly, with numerous studies challenging traditional concepts, investigating previously untested theories and incorporating a greater appreciation of the visual and cognitive systems of the observer. Using studies of both real animals and artificial systems, this book synthesises the current state of play in camouflage research and understanding. It introduces the different types of camouflage and how they work, including background matching, disruptive coloration and obliterative shading. It also demonstrates the methodologies used to study them and discusses how camouflage relates to other subjects, particularly with regard to what it can tell us about visual perception. The mixture of primary research and reviews shows students and researchers where the field currently stands and where exciting and important problems remain to be solved, illustrating how the study of camouflage is likely to progress in the future.

The Oxford Animal Biology Series is an innovative new series of supplementary undergraduate texts in comparative animal biology. Topics within each book are addressed using examples from throughout the animal kingdom, looking for parallels that transcend taxonomy. Further reading sections will guide the student into the literature at greater depth. The series will be international in scope, both in terms of the species used as examples and in references to scientific work. Energy for Animal Life, the first book in the series, is about how animals get energy, and how they use it, a central topic in our understanding of animal biology. Life depends on energy, and much of the activity of animals is devoted to getting the food which is their energy source. It encompasses the food chain, from solar radiation and photosynthesis to food sources for herbiviores and for carnivores, and compares the merits of different designs of digestive system, and of different strategies for finding and choosing food. Of course, animal energy isn't simply a question of feeding, and several chapters in turn look at energy use. The energy costs of motion - of running, swimming, and flight - are discussed in one chapter, and the energetic demands of growth and reproduction in another. A chapter on body temperature shows how the processes of life go faster at higher temperatures, and discusses how animals regulate their temperature. A final chapter draws all of these aspects of energy use together, and considers the energy budgets of several different animals, assessing the different energy gains and costs of their everyday activities in the wild. The book is truly comparative, drawing on examples from a wide range of animal species, and lots of practical information on relevant experiments is included. The style is very accessible, and suitable as supplementary reading for first and second year undergraduates taking a degree course in biological sciences.

This book covers hot topics in the nutrition and metabolism of terrestrial and aquatic animals, including the interorgan transport and utilization of water, minerals, amino acids, glucose, and fructose; the development of alternatives to in-feed antibiotics for animals (e.g., swine and poultry); and metabolic disorders (or diseases) resulting from nutrient deficiencies. It enables readers to understand the crucial roles of nutrients in the nutrition, growth, development, and health of animals. Such knowledge has important implications for humans. Readers will also learn from well-written chapters about the use of new genome-editing biotechnologies to generate animals (e.g., cows and swine) as bioreactors that can produce large amounts of pharmaceutical proteins and other molecules to improve the health and well-being of humans and other animals, as well as the growth and productivity of farm animals. Furthermore, the book provides useful information on the use of animals (e.g., cattle, swine, sheep, chickens, and fish) as models in biomedical research to prevent and treat human diseases, develop infant formulas, and improve the cardiovascular and metabolic health of offspring with prenatal growth restriction. Editor of this book is an internationally recognized expert in nutrition and metabolisms. He has about 40 years of experience with research and teaching at world-class universities in the subject matters. He has published more than 660 papers in peer-reviewed journals, 90 chapters in books, and authored two text/reference books, with a very high H-index of 127 and more than 66,000 citations in Google Scholar. This publication is a useful reference for nutrition and biomedical professionals, as well as undergraduate and graduate students in animal science, aquaculture, zoology, wildlife, veterinary medicine, biology, biochemistry, food science, nutrition, pharmacology, physiology, toxicology, and other related disciplines. In addition, all chapters provide general and specific references to nutrition and metabolism for researchers and practitioners in animal agriculture (including aquaculture), dietitians, animal and human medicines, and for government policy makers.

This book is the result of more than 20 years of experience in working with near-infrared spectroscopy for raw milk analysis. The totality of this work presents extensive possibilities for milk spectral measurements that can be carried out in dairy. Moving beyond the standard milk components such as fat, protein, or lactose, this book presents near-infrared spectroscopy as a method that can also be used in disease diagnostics. The measurements and experimental results presented here are all based on the utilization of usually neglected near-infrared regions-regions with strong absorbance of water. The author has found the water - light interaction discussed to be an immensely rich source of information, not only on milk composition but also on the physiological status of the animals involved. A special section of the book is dedicated to exploration of potential interfering factors that may influence the analysis and contribute to the robustness of the models. The research described in this book served as a basis for the development of the novel discipline aquaphotomics and is of interest to anyone working in this field.

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.

Of interest to researchers, clinicians, and advanced students in neuroscience, psychology, and neurology, the text also has important implications for researchers in biomedical engineering and robotics.

This comprehensive textbook provides detailed information on calving management in dairy and beef cattle. Enriched with diverse learning opportunities, it conveys the fundamentals of reproductive anatomy and physiology, parturition, birth complications and various obstetrical manoeuvres, as well as dam and calf care. In order to promote best practices in this specialized subject, the book covers all significant points from conception to calving and the perinatal period. Clear chapter structures, a wealth of illustrations and videos, obstetrical case studies, and question-and-answer lists round out the reading experience, making the book a unique source of information on how to support mother cows and obtain viable offspring. In addition, readers can download the free Springer Nature Flashcards App and benefit from 77 digital study questions to test their knowledge. Calving is a significant event in terms of providing care and nutrition for mother cows and calves. The reproductive health status in cattle farms is crucial to immediately initiate lactation and new conception. Assistance by technical personnel, dystocia and stillbirth occurrences can reach ca. 50%, 14% and 6% of parturitions, respectively. Hence, zootechnical and veterinary management of calving is of great importance for animal welfare. This textbook makes a valuable contribution to teaching and everyday practice in cattle medicine and obstetrics. Veterinary students, residents, practitioners and technical personnel will discover it to be a rich learning and reference resource.

Bioenergetics is the name given to the collection of disciplines within biochemistry and physiology that aims at a description and understanding of the function of living systems. These functions include the exchange, metabolism and accumulation of matter, as well as their related energy transformations. The authors present an accessible textbook, providing the reader with the fundamental principles of the subject and how these can then be applied to practical problems. This textbook is ideal for graduate students and researchers in biochemistry, physiology and chemistry. The book should also be of interest to workers in the applied life sciences.

Although most often considered in terms of the generation of action potentials, there are several other electrical, metabolic and ionic correlates of neuronal activity. This book draws together in a single volume, ten different facets of the activity of nerve cells. There are chapters on the monitoring of extracellular unit activity, intracellular voltage and current clamping, patch clamping, video imaging, in vivo voltammetry, intracerebral dialysis, antibody micro- and ion-selective electrodes. The techniques described range from the well-established to the experimental. In each case the chapters include up-to-date information, methodological tips and detailed protocols allowing the reader to follow each method in a stepwise fashion. The wide range of techniques in the book should be of interest to neuroscientists, whether concerned with traditional or novel indices on neuronal function.

Throughout history, hearing and sound perception have been typically framed in the context of how sound conveys information and how that information influences the listener. "Hear Where We Are" inverts this premise and examines how humans and other hearing animals use sound to establish acoustical relationships with their surroundings. This simple inversion reveals a panoply of possibilities by which we can re-evaluate how hearing animals use, produce, and perceive sound. Nuance in vocalizations become signals of enticement or boundary setting; silence becomes a field ripe in auditory possibilities; predator/prey relationships are infused with acoustic deception, and sounds that have been considered territorial cues become the fabric of cooperative acoustical communities. This inversion also expands the context of sound perception into a larger perspective that centers on biological adaptation within acoustic habitats. Here, the rapid synchronized flight patterns of flocking birds and the tight maneuvering of schooling fish becomes an acoustic engagement. Likewise, when stridulating crickets synchronize their summer evening chirrups, it has more to do with the 'cricket community' monitoring their collective boundaries rather than individual crickets establishing 'personal' territory or breeding fitness. In "Hear Where We Are" the author continuously challenges many of the bio-acoustic orthodoxies, reframing the entire inquiry into sound perception and communication. By moving beyond our common assumptions, many of the mysteries of acoustical behavior become revealed, exposing a fresh and fertile panorama of acoustical experience and adaptation.

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.

Dental Functional Morphology offers an alternative to the received wisdom that teeth merely crush, cut, shear or grind food and shows how teeth adapt to diet. Providing an analysis of tooth action based on an understanding of how food particles break, it shows how tooth form from the earliest mammals to modern-day humans can be understood using very basic considerations about fracture. It outlines the theoretical basis step by step, explaining the factors governing tooth shape and size and provides an allometric analysis that will revolutionize attitudes to the evolution of the human face and the impact of cooked foods on our dentition. In addition, the basis of the mechanics behind the fracture of different types of food, and methods of measurement are given in an easy-to-use appendix. It will be an important sourcebook for physical anthropologists, dental and food scientists, palaeontologists and those interested in feeding ecology.

The axolotl, or Mexican salamander, is used in a wide range of biological research, from the study of the regulation of gene expression to pattern formation, neurobiology, and regeneration. This volume offers a short yet comprehensive survey of basic developmental research utilizing the animal, along with practical information for rearing and maintaining the axolotl in a laboratory environment. The book will serve as a useful reference for developmental biologists.

However well the anatomy of the gastro-intestinal tracts of a wide range of mammals is described and quantified, there can be no real explanation of observed patterns without consideration of the mechanical and chemical properties of the food consumed, and of the digestive stages involved in its processing. This book aims to integrate findings from the many different types of investigations of mammalian digestive systems into a coherent whole. Using the themes of food, form and function, researchers discuss models of digestive processes, linking this with evolutionary aspects of food utilisation. Macroscopic and ultrastructural studies of the gastro-intestinal tract are also presented, as are physiological, ecological and biochemical aspects of the digestion of different food types. The book ends with an integrative chapter, bringing together the themes running through the earlier sections.

Animal Eyes provides a comparative account of all known types of eye in the animal kingdom, outlining their structure and function with an emphasis on the nature of the optical systems and the physical principles involved in image formation. A universal theme throughout the book is the evolution and taxonomic distribution of each type of eye, and the roles of different eye types in the behaviour and ecology of the animals that possess them. In comparing the specific capabilities of eyes, it considers the factors that lead to good resolution of detail and the ability to function under a wide range of light conditions. This new edition is fully updated throughout, incorporating more than a decade of new discoveries and research.

Exactly how modern humans evolved is a subject of intense debate. This book deals with the evolution of modern humans from an archaic ancestor and the differentiation of modern populations from each other. The first section of the book investigates whether modern populations arose from regional archaic hominid groups that were already different from each other, and argues that in fact, most lines of evidence support a single, recent origin of modern humans in Africa. Dr Lahr then goes on to examine ways in which this diversification could have occurred, given what we know from fossils, archaeological remains and the relationships of existing populations today. This book will be a must for all those interested in human evolution.

Smooth muscles line many internal organs and, in general, are involved in moving fluids and slurry around the body. They are controlled by the action of hormones, by nervous stimulation, and can be influenced by drugs. This 1997 book provides a review of our understanding of smooth muscle and integrates molecular, cellular and physiological information with tissue and anatomical studies. Well-known researchers have written chapters giving detailed reviews of our current knowledge of the biochemistry, pharmacology, physiology and anatomy of smooth muscle. In particular, they cover the seven most important areas of smooth muscle function including morphology, electrophysiology, mechanisms of electromechanical and pharmacomechanical coupling, calcium homeostasis, signal transduction, mechanics of contraction, and the contractile proteins. All those interested in muscular contraction will find this book worthwhile, whether they are biochemists, physiologists, or cell biologists.

Skin colour is perhaps the most decisive and abused physical characteristic of humankind. This book presents a multidisciplinary overview of how and why human populations vary so markedly in their skin colour. The biological aspects of the pigment cell and its production of melanin are reviewed. The functions of melanin in the skin, brain, eye and ear are considered, and the common clinical abnormalities of pigmentation, such as albinism, are described and illustrated. Detailed reflectance data from worldwide surveys of skin colour are also presented. The historical and contemporary background of the phenomenon is explored in relation to the so-called 'colour problem' in society. Finally, the possible evolutionary forces which shape human pigmentation are assessed. This fascinating account will be of interest to graduate students and researchers of biological anthropology, anatomy, physiology and dermatology, as well as medical practitioners.

There is often confusion over the meaning and usage of terms such as efficiency, economy, effectiveness, optimization, and perfection in biology. This book defines and discusses these concepts within a broad evolutionary perspective and considers how evolutionary pressures can affect the economy and efficiency of animals. Chapters consider biomaterials, skeletal systems, muscular function, aquatic and terrestrial locomotion, and cardiovascular systems. The result is a book of interest to all biologists, particularly those working in the field of comparative physiology and evolutionary biology.

This volume provides a thought-provoking perspective on the empirical and analytic study of body form and composition. The techniques used for measuring body components such as fat, water, lean tissue, bone mass and bone density are evaluated against potential 'gold standards'. The nature of regional differences, developmental changes, pathological abnormalities, and the impact of heredity and environment in shaping body composition are discussed in the context of human evolution. All those concerned with biological anthropology, both clinicians and researchers, will find this book of great interest.
