Electroreception has become one of the most revealing areas in the study of the neural basis of behavior, and neurobiologists recognize it as a model sensory system for experimental study. Through studies of electroreception, researchers have gained extensive knowledge about a complete sensory system, from molecular biology to computation, communication, and behavior. The book Electroreception will examine the behavior, structure, and function of the electrosensory systems of fish and other vertebrates. As a comprehensive volume on the subject, the book will serve as both an introduction to the study of electroreception and a reference and review volume for researchers in related fields.

We live in a world in which inconsistency is the rule rather than the exception and this is particularly true with regard to rewards and frustrations. In some cases, rewards and frustrative nonrewards appear to occur randomly for what seems to be the same behavior; in others a sequence of rewards is suddenly followed by nonrewards, or there are large rewards followed by small rewards. Sometimes we are rewarded for responding quickly, other times for responding slowly. The important common factor in these and other cases is frustration, how we learn about it and how we respond to it. Without our awareness, our long-term dispositions are shaped from infancy and early childhood by inconsistency of reward and by our reactions to discrepancy, and they are marked by changes in arousal, suppression, persistence and regression. The explanatory domain of Frustration Theory includes an area of experimental research that has evolved over some forty years. Although most of the work is with animals, it constitutes an animal model of many of the myriad human manifestations of nonreward, thwarting of purpose, and reactions to physical and emotional insult that are regarded as frustrations. This book, by the originator of the theory and the first book to be devoted solely to Frustration Theory, gives a detailed account of the theory and its ramifications and it examines the relationship between frustration symptoms and the limbic system that is thought to be the region of the brain responsible for generating these symptoms.

Predation is considered one of the distinct phenomena related to the interrelationships between species on the Earth. In general, predation is widespread not only in wildlife but also in marine environments where big fishes eat small fishes and other organisms of the sea. This book considers predation in organisms and is aimed at the prevention of predation in wildlife and marine environments.

This book is a contribution to the history of ethology-not a definitive history, but the personal view of a major figure in that story. It is all the more welcome because such a grand theme as ethology calls for a range of perspectives. One reason is the overarching scope of the subject. Two great questions about life that constitute much of biology are "How does it work (structure and function)?" and "How did it get that way (evolu tion and ontogeny)?" Ethology addresses the antecedent of "it. " Of what are we trying to explain the mechanism and development? Surely behav ior, in all its wealth of detail, variation, causation, and control, is the main achievement of animal evolution, the essential consequence of animal structure and function, the raison d' etre of all the rest. Ethology thus spans between and overlaps with the ever-widening circles of ecol ogy over the eons and the ever-narrowing focus of physiology of the neurons. Another reason why the history of ethology needs perspectives is the recency of its acceptance. For such an obviously major aspect of animal biology, it is curious how short a time-less than three decades-has seen the excitement of an active field and a substantial fraternity of work ers, the addition of professors and courses to departments and curricula in biology (still far from universal}, and the normal complement of spe cial journals, symposia, and sessions at congresses."

This volume contains the proceedings of the conference of the same name held in July 2006 at the University of Chester in the United Kingdom. It includes all the latest research on chemical communication relevant to vertebrates, particularly focusing on new research since the last meeting in 2003. Topics covered include the chemical ecology, biochemistry, behavior, olfactory receptors, and the neurobiology of both the main olfactory and vomeronasal systems of vertebrates.

Although commonly believed that males are more promiscuous than females, new research has revealed that female infidelity is a common occurrence throughout the animal kingdom. Female Infidelity and Paternal Uncertainty is the first book to address how males deal with the consequences of female infidelity and the strategies they have evolved to try to avoid the possibility of raising an offspring they unknowingly did not sire. Each chapter deals with a specific evolved strategy developed to aid males in either limiting opportunities for their mate to be unfaithful or to 'correct' the by-products of infidelity should it occur. With sections including mate guarding, intra-vaginal tactics and paternity assessment, this book will appeal to researchers and graduate students in behavioral biology, evolutionary psychology, human sexuality, anthropology, sociology, reproductive health and medicine.

Behavioural observations from both the field and captivity indicate that same-sex sexual interactions are widespread throughout the animal kingdom, and occur quite frequently in certain non-human species. Proximate studies of these phenomena have yielded important insights into genetic, hormonal and neural correlates. In contrast, there has been a relative paucity of research on the evolutionary aspects. Homosexual Behaviour in Animals seeks to redress this imbalance by exploring animal same-sex sexual behaviour from an evolutionary perspective. Contributions focus on animals that routinely engage in homosexual behaviour and include birds, dolphin, deer, bison and cats, as well as monkeys and apes, such as macaques, gorillas and bonobos. A final chapter looks at human primates. This book will appeal to graduate students and researchers in evolutionary biology, biological anthropology, zoology, evolutionary psychology, animal behaviour and anyone interested in the current state of knowledge in this area of behavioural studies.

Most large herbivores require some type of management within their habitats. Some populations of large herbivores are at the brink of extinction, some are under discussion for reintroduction, whilst others already occur in dense populations causing conflicts with other land use. Large herbivores are the major drivers for forming the shape and function of terrestrial ecosystems. This 2006 book addresses the scientifically based action plans to manage both the large herbivore populations and their habitats worldwide. It covers the processes by which large herbivores not only affect their environment (e.g. grazing) but are affected by it (e.g. nutrient cycling) and the management strategies required. Also discussed are new modeling techniques, which help assess integration processes in a landscape context, as well as assessing the consequences of new developments in the processes of conservation. This book will be essential reading for all involved in the management of both large herbivores and natural resources.

This book covers a wide range of animals from flagellated microorganisms to marine mammals. It follows "Bio-mechanisms of Animals in Swimming and Flying" published in 2004 including 11 chapters. This time, the book includes 31 chapters on the latest researches into natural autonomous systems and locomotion in both flying and swimming organisms. The area of sports science such as analysis and simulation of human swimming is newly added. The computational frameworks for the modeling, simulation and optimization of animals in swimming and flying demonstrate an important role in the progress of interdisciplinary work in the fields of biology and engineering.

How do animals produce and process sounds for communication? How do their brains encode the large amounts of sensory information so rapidly and how do they use this to cope with their environment? These questions not only concern the evolution of sound communication systems but also aim to understand how arousal, motivation, emotion and behavioral contexts are vocally expressed and how important sound attributes are recognized and perceived. This book highlights auditory communication in several species from four perspectives: actual sound communication, audio-vocal adaptations, adaptations of sound processing and representation in higher auditory brain centers, and emotional and cognitive adaptations in signaling and processing. Broad in scope and geared towards graduate students and researchers within the fields of auditory communication and cognition, this book will appeal to auditory neurobiologists, speech, hearing and communication scientists and engineers, students of animal behavior and neuroethologists.

Gregory Bateson s contribution to 20th century thinking has appealed to scholars from a wide range of fields dealing in one way or another with aspects of communication and epistemology. A number of his insights were taken up and developed further in anthropology, psychology, evolutionary biology and communication theory. But the large, trans-disciplinary synthesis that, in his own mind, was his major contribution to science received little attention from the mainstream scientific communities.

This book represents a major attempt to revise this deficiency. Scholars from ecology, biochemistry, evolutionary biology, cognitive science, anthropology and philosophy discuss how Bateson's thinking might lead to a fruitful reframing of central problems in modern science. Most important perhaps, Bateson's bioanthropology is shown to play a key role in developing the set of ideas explored in the new field of biosemiotics. The idea that organismic life is indeed basically semiotic or communicative lies at the heart of the biosemiotic approach to the study of life.

The only book of its kind, this volume provides a key resource for the quickly-growing substratum of scholars in the biosciences, philosophy and medicine who are seeking an elegant new approach to exploring highly complex systems."

Animal welfare is attracting increasing interest worldwide, but particularly from those in developed countries, who now have the knowledge and resources to be able to improve the welfare of farm animals. The increased attention given to farm animal welfare in the West derives largely from the fact that the relentless pursuit of ?nancial reward and ef?ciency has led to the development of intensive animal production systems that disturb the conscience of many consumers. In developing countries, human survival is still a daily uncertainty, so that provision for animal welfare has to be balanced against human welfare. Welfare is usually provided for only if it supports the output of the animal, be it food, work, clothing, sport or companionship. In reality there are resources for all if they are properly husbanded in both developing and developed countries. The inequitable division of the world's riches creates physical and psychological poverty for humans and animals alike in many sectors of the world. Livestock are the world's biggest land user (FAO, 2002) and the population is increasing rapidly to meet the need of an expanding human population. Populations of farm animals managed by humans are therefore incre- ing worldwide, and in some regions there is a tendency to allocate fewer resources, such as labour, to each animal with potentially adverse consequences on the a- mals' welfare.

The domestic pig is perceived as an animal with intelligence and character and yet, in the industrialized world, the majority of people have had little or no contact with them. Pigs are subject to a wide range of environments from the tropics to the sub-arctic, ranging from small-scale, extensive systems to large-scale intensive systems. They may spend their whole life on one farm or may be subject to long-distance transport multiple times. Not surprisingly, many aspects of their life experiences can impact their welfare.

This book brings together a team of leading pig welfare research scientists to review the natural history of the pig, the welfare of pigs at different stages of life and to indicate what the future holds in terms of pig welfare. The text is aimed at researchers and teachers working in veterinary and animal science together with those working in the pig industry and for governmental and non-governmental animal welfare organizations.

Males and females often differ in developmental patterns, adult morphology, ecology and behaviour, and in many mammals males are often larger. Size dimorphism results in divergent nutritional and energetic requirements or reproductive strategies by the sexes, which in turn sometimes causes them to select different forage, use different habitats, and express differing social affinities. Such divergent life-styles often lead males and females to live large parts of their lives separately. Sexual segregation is widespread in animals. Males and females may share the same habitat, but at different times, for example, or they might use different habitats entirely. Why did sexual segregation evolve and what factors contribute to it? Sexual Segregation in Vertebrates explores these questions by looking at a wide range of vertebrates and is aimed as a synthesis of our current understanding and a guide for future research.

Elephants have captivated the human imagination for as long as they have roamed the earth, appearing in writings and cultures from thousands of years ago and still much discussed today. In Thirty-Three Ways of Looking at an Elephant, veteran scientific writer Dale Peterson has collected thirty-three essential writings about elephants from across history, with geographical perspectives ranging from Africa and Southeast Asia to Europe and the United States. An introductory headnote for each selection provides additional context and insights from Peterson's substantial knowledge of elephants and natural history. The first section of the anthology, "Cultural and Classical Elephants," explores the earliest mentions of elephants in African mythology, Hindu theology, and Aristotle and other ancient Greek texts. "Colonial and Industrial Elephants" finds elephants in the crosshairs of colonial exploitation in accounts pulled from memoirs commodifying African elephants as a source of ivory, novel targets for bloodsport, and occasional export for circuses and zoos. "Working and Performing Elephants" gives firsthand accounts of the often cruel training methods and treatment inflicted on elephants to achieve submission and obedience. As elephants became an object of scientific curiosity in the mid-twentieth century, wildlife biologists explored elephant families and kinship, behaviors around sex and love, language and self-awareness, and enhanced communications with sound and smell. The pieces featured in "Scientific and Social Elephants" give readers a glimpse into major discoveries in elephant behaviors. "Endangered Elephants" points to the future of the elephant, whose numbers continue to be ravaged by ivory poachers. Peterson concludes with a section on literary elephants and ends on a hopeful note with the 1967 essay "Dear Elephant, Sir," which argues for the moral imperative to save elephants as an act of redemption for their systematic abuse and mistreatment at human hands. Essential to our understanding of this beloved creature, Thirty-Three Ways of Looking at an Elephant is a must for any elephant lover or armchair environmentalist.

Dr. Dolittle-and many students of animal communication-are wrong: animals cannot use language. This fascinating book explains why. Can animals be taught a human language and use it to communicate? Or is human language unique to human beings, just as many complex behaviors of other species are uniquely theirs? This engrossing book explores communication and cognition in animals and humans from a linguistic point of view and asserts that animals are not capable of acquiring or using human language. Stephen R. Anderson explains what is meant by communication, the difference between communication and language, and the essential characteristics of language. Next he examines a variety of animal communication systems, including bee dances, frog vocalizations, bird songs, and alarm calls and other vocal, gestural, and olfactory communication among primates. Anderson then compares these to human language, including signed languages used by the deaf. Arguing that attempts to teach human languages or their equivalents to the great apes have not succeeded in demonstrating linguistic abilities in nonhuman species, he concludes that animal communication systems-intriguing and varied though they may be-do not include all the essential properties of human language. Animals can communicate, but they can't talk.

This innovative book challenges the perceived view, based largely on long observation of artificially-fed chimpanzees in Gombe and Mahale National Parks, Tanzania, of the typical social behaviour of chimpanzees as aggressive, dominance seeking, and fiercely territorial. In polar opposition, all reports from naturalistic (non-feeding) field studies are of non-aggressive chimpanzees living peacefully in non-hierarchical groups, on home ranges open to all. These reports have been ignored and downgraded by most of the scientific community. By utilising the data from these studies the author is able to construct a model of an egalitarian form of social organisation, based on a fluid role relationship of mutual dependence between many charismatic chimpanzees of both sexes and other more dependent members. This highly and necessarily positive mutual dependence system is characteristic of both (undisturbed) chimpanzees and (undisturbed) humans who live by the 'immediate-return' foraging system.

The hunger for sodium has been used as a model system in which to study how the brain produces motivated behaviour. In this account of the field Jay Schulkin draws together information across a range of disciplines and topics, ranging from the ecology of salt ingestion to the sodium molecule and the action of various hormones. The phenomenon of sodium hunger was discovered by Curt Richter, the great American psychobiologist, over 50 years ago. Its study has been of interest for some time: to naturalists, psychologists, endocrinologists, physiologists and neuroscientists. This book offers a systematic account of the behaviour of the sodium hungry animal, the endocrine and physiological mechanisms that act to maintain sodium balance and then act on the brain to promote the search for and the ingestion of salt. Finally, the book provides a description of a neural network that orchestrates the behaviour of salt seeking and salt ingestion. Graduate students and research workers in psychology, physiology and neuroscience will find valuable information in this review.

Plants provide insects with a range of specific foods, such as nectar, pollen and food bodies. In exchange, they may obtain various services from arthropods. The role of food rewards in the plant-pollinator mutualism has been broadly covered. This book, first published in 2005, addresses another category of food-mediated interactions, focusing on how plants employ foods to recruit arthropod 'bodyguards' as a protection against herbivores. Many arthropods with primarily carnivorous lifestyles require plant-provided food as an indispensable part of their diet. Only recently have we started to appreciate the implications of non-prey food for plant-herbivore-carnivore interactions. Insight into this aspect of multitrophic interactions is not only crucial to our understanding of the evolution and functioning of plant-insect interactions in natural ecosystems, it also has direct implications for the use of food plants and food supplements in biological control programs. This edited volume provides essential reading for all researchers interested in plant-insect interactions.

From the co-author of the New York Times bestseller When Elephants Weep comes a book that uses true stories backed by scientific research to explore the way young animals discover their worlds and learn how to survive.

How does a baby animal figure out how to get around in the world? How much of what animals know is instinctive, and how much must they learn?

In Becoming a Tiger, bestselling author Susan McCarthy addresses these intriguing matters, presenting fascinating and funny examples of animal behaviour in the laboratory and in the wild. McCarthy shows us how baby animals transform themselves from clueless kittens, clumsy cubs, or scrawny chicks into efficient predators, successful foragers, or deft nest-builders. From geese to mice, dolphins to orang-utans, bats to (of course) tigers, McCarthy's warm, amusing, and insightful examinations of animal life and developments provides a surprising window into the mental worlds of our fine fuzzy, furred, finned, and feathered friends.

oReaders will be fascinated by a close look at animal intelligence, learning, and family life.

When and where did the ancestors of modern birds evolve? What enabled them to survive the meteoric impact that wiped out the dinosaurs? How did these early birds spread across the globe and give rise to the 10,600-plus species we recognise today from the largest ratites to the smallest hummingbirds? Based on the latest scientific discoveries and enriched by personal observations, The Ascent of Birds sets out to answer these fundamental questions. The Ascent of Birds is divided into self-contained chapters, or stories, that collectively encompass the evolution of modern birds from their origins in Gondwana, over 100 million years ago, to the present day. The stories are arranged in chronological order, from tinamous to tanagers, and describe the many dispersal and speciation events that underpin the world's 10,600-plus species. Although each chapter is spearheaded by a named bird and focuses on a specific evolutionary mechanism, the narrative will often explore the relevance of such events and processes to evolution in general. The book starts with The Tinamou's Story, which explains the presence of flightless birds in South America, Africa, and Australasia, and dispels the cherished role of continental drift as an explanation for their biogeography. It also introduces the concept of neoteny, an evolutionary trick that enabled dinosaurs to become birds and humans to conquer the planet. The Vegavis's Story explores the evidence for a Cretaceous origin of modern birds and why they were able to survive the asteroid collision that saw the demise not only of dinosaurs but of up to three-quarters of all species. The Duck's Story switches to sex: why have so few species retained the ancestral copulatory organ? Or, put another way, why do most birds exhibit the paradoxical phenomenon of penis loss, despite all species requiring internal fertilisation? The Hoatzin's Story reveals unexpected oceanic rafting from Africa to South America: a stranger-than-fiction means of dispersal that is now thought to account for the presence of other South American vertebrates, including geckos and monkeys. The latest theories underpinning speciation are also explored. The Manakin's Story, for example, reveals how South America's extraordinarily rich avifauna has been shaped by past geological, oceanographic and climatic changes, while The Storm-Petrel's Story examines how species can evolve from an ancestral population despite inhabiting the same geographical area. The thorny issue of what constitutes a species is discussed in The Albatross's Story, while The Penguin's Story explores the effects of environment on phenotype in the case of the Emperor penguin, the harshest on the planet. Recent genomic advances have given scientists novel approaches to explore the distant past and have revealed many unexpected journeys, including the unique overland dispersal of an early suboscine from Asia to South America (The Sapayoa's Story) and the blackbird's ancestral sweepstake dispersals across the Atlantic (The Thrush's Story). Additional vignettes update more familiar concepts that encourage speciation: sexual selection (The Bird-of-Paradise's Story); extended phenotypes (The Bowerbird's Story); hybridisation (The Sparrow's Story); and 'great speciators' (The White-eye's Story). Finally, the book explores the raft of recent publications that help explain the evolution of cognitive skills (The Crow's Story); plumage colouration (The Starling's Story); and birdsong (The Finch's Story)

Shaping Primate Evolution is an edited collection of state-of-the-art papers about how biological form is described in primate biology, and the consequences of form for function and behavior. The contributors are highly regarded internationally recognized scholars in the field of quantitative primate evolutionary morphology. Each chapter elaborates upon the analysis of the form-function-behavior triad in a unique and compelling way. This book is distinctive not only in the diversity of the topics discussed, but also in the range of levels of biological organization that are addressed from cellular morphometrics to the evolution of primate ecology. The book is dedicated to Charles E. Oxnard, whose influential pioneering work on innovative metric and analytic techniques has gone hand-in-hand with meticulous comparative functional analyses of primate anatomy. Through the marriage of theory with analytical applications, this volume will be an important reference work for all those interested in primate functional morphology.

Cooperative breeders are species in which more than a pair of individuals assist in the production of young. Cooperative breeding is found in only a few hundred bird species world-wide, and understanding this often strikingly altruistic behaviour has remained an important challenge in behavioural ecology for over 30 years. This book highlights the theoretical, empirical and technical advances that have taken place in the field of cooperative breeding research since the publication of the seminal work Cooperative Breeding in Birds: Long-term Studies of Behavior and Ecology (1990, HB ISBN 0521 372984, PB ISBN 0521 378907). Organized conceptually, special attention is given to ways in which cooperative breeders have proved fertile subjects for testing modern advances to classic evolutionary problems including those of sexual selection, sex-ratio manipulation, life-history evolution, partitioning of reproduction and incest avoidance. It will be of interest to both students and researchers interested in behaviour and ecology.

Unlike most other large mammals, the Soay sheep population of Hirta in the St. Kilda archipelago show persistent oscillations, sometimes increasing or declining by more than 60% in a year. This study explores the causes of these oscillations and their consequences for selection on genetic and phenotypic variation within the population, drawing on studies over the past twenty years of the life-histories and reproductive careers of many sheep. It will be essential reading for vertebrate ecologists, demographers, evolutionary biologists and behavioral ecologists.

Why do birds often live in pairs and rear chicks together, whereas female mammals usually live in groups and rear their young without male help? Why do males sometimes live with a single mate when they are capable of fertilizing more than one female's eggs? Is male helping behavior important for monogamous partnerships? This book provides answers concerning the biological roots of social monogamy in animal groups as diverse as ungulates, carnivores, rodents, birds and primates (including humans) for students and researchers in behavioral ecology, evolutionary anthropology and zoology.
