In this first comprehensive synthesis of the literature on food hoarding in animals, Stephen B. Vander Wall discusses how animals store food, how they use food and how this use affects individual fitness, why and how food hoarding evolved, how cached food is lost, mechanisms for protecting and recovering cached food, physiological and behavioral factors that influence hoarding, and the impact that hoarding animals have on plant populations and plant dispersal. He then provides detailed coverage of hoarding behavior across taxa--mammals, birds, and arthropods--to address issues in evolution, ecology, and behavior.
Drawings, photographs, and appendixes document complex and intrinsically interesting food-hoarding behaviors, and the bibliography of nearly 1,500 sources is itself an invaluable and unique reference.

Body fluid regulation is pivotal to human health and is served by extensive clinical and pre-clinical science. By combining modern advances with previous findings in the field, this book presents a comprehensive treatment of major experiments, theories, and new advances in the field of body fluid regulation, thirst, and drinking. It features the main integrative brain mechanisms for fluid regulation, the development of such systems, fluid balance during heat and exercise, aging and clinical disorders, and comparative aspects of fluid regulation. The volume focuses on mammalian thirst or drinking behaviour alongside relevant aspects of the physiology of fluid balance. The principal fluid compartments and their regulation by both intakes and losses are highlighted, using both human and animal studies to illustrate the main concepts.

Better known as the "predator-prey relationship," the consumer-resource relationship means the situation where a single species of organisms consumes for survival and reproduction. For example, Escherichia coli consumes glucose, cows consume grass, cheetahs consume baboons; these three very different situations, the first concerns the world of bacteria and the resource is a chemical species, the second concerns mammals and the resource is a plant, and in the final case the consumer and the resource are mammals, have in common the fact of consuming. In a chemostat, microorganisms generally consume (abiotic) minerals, but not always, bacteriophages consume bacteria that constitute a biotic resource. 'The Chemostat' book dealt only with the case of abiotic resources. Mathematically this amounts to replacing in the two equation system of the chemostat the decreasing function by a general increasing then decreasing function. This simple change has greatly enriched the theory. This book shows in this new framework the problem of competition for the same resource.

This book explores the relationship between cellular processes and animal behaviour. It does this by focusing on the domain of navigation, bringing together scientists from either side of the brain-behaviour divide in an attempt to explain the linkage between spatial behaviour and the underlying activity of neurons.

The Neurobiology of Spatial Behaviour is organised into two sections. Section one deals with the so-called 'higher' levels of description - studies of spatial behaviour and the brain areas that might underlie such behaviour. The section begins with insects, remarkably sophisticated navigators, and ends with humans, examining along the way issues such as whether animal brains contain maps and whether spatial and non-spatial information interact, and if so, how? Section two delves further into the brain and focuses on the mammalian representation of space and the role of place cells.

These issues have far wider ramifications that simply helping us to understand the process of navigation. This system might provide a model for how other forms of knowledge, beliefs and intentions are encoded in neurons. As such, the book will be of interest to an interdisciplinary audience, including ethologists, psychologists, behavioural neuroscientists, computational modelers, physiological neuroscientists and molecular biologists.

In 1953 a young female Japanese macaque called Imo began washing sweet potatoes before eating them, presumably to remove dirt and sand grains. Soon other monkeys had adopted this behaviour, and potato-washing gradually spread throughout the troop. When, three years after her first invention, Imo devised a second novel foraging behaviour, that of separating wheat from sand by throwing mixed handfuls into water and scooping out the floating grains, she was almost instantly heralded around the world as a 'monkey genius'. Imo is probably the most celebrated of animal innovators. In fact, many animals will invent new behaviour patterns, adjust established behaviours to a novel context, or respond to stresses in an appropriate and novel manner.

Innovation is an important component of behavioural flexibility, vital to the survival of individuals in species with generalist or opportunistic lifestyles, and potentially of critical importance to those endangered or threatened species forced to adjust to changed or impoverished environments. Innovation may also have played a central role in avian and primate brain evolution. Yet until recently animal innovation has been subject to almost complete neglect by behavioural biologists, psychologists, social learning researchers, and conservation-minded biologists.

This collection of stimulating and readable articles by leading scientific authorities is the first ever book on 'animal innovation', designed to put the topic of animal innovation on the map and heighten awareness of this developing field.

Originally published in 1988, this title explores and contrasts means and ends psychology with conventional psychology - that of stimuli and response. The author develops this comparison by exploring the general nature of psychological phenomena and clarifying many persistent doubts about psychology. She contrasts conventional psychology (stimuli and responses) involving reductionistic, organocentric, and mechanistic metatheory with alternative psychology (means and ends) that is autonomous, contextual, and evolutionary.

In social relationships-whether between mates, parents and offspring, or friends-we find much of life's meaning. But in these relationships, so critical to our well-being, might we also detect the workings, even directives, of biology? This book, a rare melding of human and animal research and theoretical and empirical science, ventures into the most interesting realms of behavioral biology to examine the intimate role of endocrinology in social relationships. The importance of hormones to reproductive behavior-from breeding cycles to male sexual display-is well known. What this book considers is the increasing evidence that hormones are just as important to social behavior. Peter Ellison and Peter Gray include the latest findings-both practical and theoretical-on the hormonal component of both casual interactions and fundamental bonds. The contributors, senior scholars and rising scientists whose work is shaping the field, go beyond the proximate mechanics of neuroendocrine physiology to integrate behavioral endocrinology with areas such as reproductive ecology and life history theory. Ranging broadly across taxa, from birds and rodents to primates, the volume pays particular attention to human endocrinology and social relationships, a focus largely missing from most works of behavioral endocrinology.

Ever since Darwin, science has enshrined competition as biology's brutal architect. But this revelatory new book argues that our narrow view of evolution has caused us to ignore the generosity and cooperation that exist around us, from the soil to the sky. In Sweet in Tooth and Claw, Kristin Ohlson explores the subtle ways in which nature is in constant collaboration to the betterment of all species. From the bear that discards the remainders of his salmon dinner on the forest ground, to the bright coral reefs of Cuba, she shows readers not only the connectivity lying beneath the surface in natural ecosystems, but why it's vital for humans to incorporate that understanding into our interactions with nature, and also with each other. Much of the damage that humans have done to our natural environment stems from our ignorance of these dense webs of connection. As we struggle to cope with the environmental hazards that our behaviour has unleashed, it's more important than ever to understand nature's billions of cooperative interactions. This way, we can stop disrupting them and instead rely on them to renew ecosystems. In reporting from the frontlines of scientific research, regenerative agriculture, and urban conservation, Ohlson shows that a shift from focusing on competition to collaboration can heal not only our relationships with the natural world, but also with each other.

Evolutionary change is usually incremental and continuous, but some increases in organizational complexity have been radical and divisive. Evolutionary biologists, who refer to such events as "major transitions", have not always appreciated that these advances were novel forms of pairwise commitment that subjugated previously independent agents. Inclusive fitness theory convincingly explains cooperation and conflict in societies of animals and free-living cells, but to deserve its eminent status it should also capture how major transitions originated: from prokaryote cells to eukaryote cells, via differentiated multicellularity, to colonies with specialized queen and worker castes. As yet, no attempt has been made to apply inclusive fitness principles to the origins of these events. Domains and Major Transitions of Social Evolution develops the idea that major evolutionary transitions involved new levels of informational closure that moved beyond looser partnerships. Early neo-Darwinians understood this principle, but later social gradient thinking obscured the discontinuity of life's fundamental organizational transitions. The author argues that the major transitions required maximal kinship in simple ancestors - not conflict reduction in already elaborate societies. Reviewing more than a century of literature, he makes testable predictions, proposing that open societies and closed organisms require very different inclusive fitness explanations. It appears that only human ancestors lived in societies that were already complex before our major cultural transition occurred. We should therefore not impose the trajectory of our own social history on the rest of nature. This thought-provoking text is suitable for graduate-level students taking courses in evolutionary biology, behavioural ecology, organismal developmental biology, and evolutionary genetics, as well as professional researchers in these fields. It will also appeal to a broader, interdisciplinary audience, including the social sciences and humanities.

Arthropods as pests in crops, vectors of diseases, pollinators, and natural enemies of pests are of huge economic importance. They affect livestock, human health and food supplies around the world. This unique book examines and reviews how light and colour can be used to enhance pest management in agricultural and medical applications by manipulating the optical responses of arthropods. Arthropods use optical cues to find food, oviposition sites and to navigate. Light also regulates their diurnal and seasonal activities. Plants use optical cues to attract or deter various species of arthropod. In this book, an international team of experts show how light can be used successfully to attract, arrest, confuse and deter arthropods as well as to disrupt their biological clocks. The book: Presents an up-to-date and thorough summary of what is known about how arthropods of agricultural and medical importance respond to visual cues. Describes techniques that use light to manipulate pests and beneficial insects and mites. Presents a broad discussion of the potential use of optical manipulation of arthropods to improve the health of plants, domestic animals and humans.

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.

One of the main tenets of evolutionary biology is that organisms behave so as to maximize the number of their genes that will be passed on to future generations. Parents often produce more offspring than they can rear in case special opportunities or calamities occur. This frequently leads to deprivations and even death of some offspring. This book is about the evolutionary diversity, importance, and consequences of such squeezes. The authors, experts in their field, review the theory, field experiments, and natural history of sibling rivalry across a broad sweep of organisms, in an accessible style that should appeal to both academics and natural historians. This book is intended for graduate students and researchers in evolutionary biology, animal behaviour, ecology, population biology, and in philosophy or social sciences as well as for ornithologists and natural historians.

Why is blood thicker than water'? Are we innately violent or pacific? Why are plants and animals sexual? Why do we grow old and die? Such questions have motivated the life-work of W.D. Hamilton, widely acknowledged as the most important theoretical biologist of the 20th century. His papers continue to exert an enormous influence and they are now being republished for the first time. This first volume contains all of Hamilton's publications prior to 1981, a set especially relevant to social behavior, kinship theory, sociobiology, and the notion of selfish genes'. Each paper is introduced by an autobiographical essay written especially for this collection. Accessible to non-specialists, this fascinating volume features several of the most read and famous papers of modern biology.

Evolution of Learning and Memory Mechanisms is an exploration of laboratory and field research on the many ways that evolution has influenced learning and memory processes, such as associative learning, social learning, and spatial, working, and episodic memory systems. This volume features research by both outstanding early-career scientists as well as familiar luminaries in the field. Learning and memory in a broad range of animals are explored, including numerous species of invertebrates (insects, worms, sea hares), as well as fish, amphibians, birds, rodents, bears, and human and nonhuman primates. Contributors discuss how the behavioral, cognitive, and neural mechanisms underlying learning and memory have been influenced by evolutionary pressures. They also draw connections between learning and memory and the specific selective factors that shaped their evolution. Evolution of Learning and Memory Mechanisms should be a valuable resource for those working in the areas of experimental and comparative psychology, comparative cognition, brain-behavior evolution, and animal behavior.

The hardback edition of this was the first book on insect flight since J W S Pringle's classic Insect Flight was published in 1957. Much has been written since on applied and ecological aspects of flight, but the question of the origin of wings and flight, their structural concomitants, and the related aerodynamical issues have been confined largely to armchair speculation in a scattered literature. This book is written by a leading authority on insect flight, and for the first time draws a coherent, empirically based picture of how insect flight may have evolved. Following excellent reviews the book is now being made available in paperback.

A beautifully written account of the symbiotic relationship between pine trees and jays; a cycle of dependency has progressed for several million years as birds have effectively planted the trees that sustain them by dispersing the seeds. This book covers a wide range of regions, focusing on the Rocky Mountains and the American Southwest, but also ranging from the Alps to Finland, and from Siberia to China. The book is written from the perspectives of evolution, ecology, and animal behaviour.

The field of nonverbal communication is a strategic site for demonstrating the inextricable interrelationship between nature and culture in human behaviour. This book, originally published in 1997, aims to explode the misconception that "biology" is something that automatically precludes or excludes "culture". Instead, it points to the necessary grounding of our social and cultural capabilities in biological givens and elucidates how biological factors are systematically co-opted for cultural purposes. The book presents a complex picture of human communicative ability as simultaneously biologically and socioculturally influenced, with some capacities apparently more biologically hard-wired than others: face recognition, imitation, emotional communication, and the capacity for language. It also suggests that the dividing line between nonverbal and linguistic communication is becoming much less clear-cut. The contributing authors are leading researchers in a variety of fields, writing here for a general audience. The book is divided into sections dealing with, respectively, human universals, evolutionary and developmental aspects of nonverbal behaviour within a sociocultural context, and finally, the multifaceted relationships between nonverbal communication and culture.

Originally published in 1978, this book is a collection of chapters based on the papers read at a conference in 1976 at Dalhousie University in Halifax, Nova Scotia. The title starts with an introductory essay in which a metatheoretical and philosophical approach to the problem of cognition in animals is discussed. The succeeding chapters are arranged, topically, from basic associative processes to higher mental operations. Problems derived from models of association are discussed; as well as work on attention, memory, and the processing of stimulus information; other deal with time, spatial, and serial organization of behaviour, and concept formation.

Our views on human nature are fundamental to the whole development, indeed the whole future, of human society. Originally published in 1974, Professor Thorpe believed that this was one of the most important and significant topics to which a biologist can address himself, and in this book he attempts a synthetic view of the nature of man and animal based on the five disciplines of physiology, ethology, genetics, psychology and philosophy. In a masterly survey of the natural order he shows the animal world as part of, yet distinct from, the inanimate world. He then treats aspects of the animal world which approach the human world in behaviour and capabilities, examining simple organisms, communications in vertebrates and invertebrates, innate behaviour versus acquired behaviour, and animal perception. In the second part of the book he deals with those aspects of human nature for which there is no analogy and which constitute man's uniqueness - his consciousness of his past, his awareness of his future and his desire to understand the meaning of his existence. The primary facts which demonstrate the importance of this book arise from the ever-growing power of man over his environment and his apparent inability to foresee and cope with the dangers of uncontrolled population growth on the one hand and the wildly irrational waste and degradation of the natural resources of the world on the other. Professor Thorpe believes that an immense responsibility lies with literate men of good will, particularly scientists, to convince man that he is the spearhead and custodian of a stupendous evolutionary process. Animal Nature and Human Nature integrates scientific fact with sound theological thought in an attempt to fulfil, in a manner previously impossible Pascal's injunction that: 'It is dangerous to show man too clearly how much he resembles the beast without at the same time showing him his greatness. It is also dangerous to allow him too clear a vision of his greatness without his baseness. It is even more dangerous to leave him in ignorance of both. But it is very profitable to show him both.'

What is a juvenile? Why do primates take so long to grow up? What forces shape the behavior of juvenile primates, and how do experiences during these early years influence life as an adult? Juvenile Primates is the first book to focus specifically on the primate juvenile period. Using a life-history approach, contributors to this volume consider the paradoxes inherent in the unusually long juvenile process exhibited by primates as they present new data on the challenges faced by juveniles across a broad range of species. Individual chapters focus on prosimians, Old and New World monkeys, apes, and humans, and topics include the development of sex differences, meeting needs for safety, establishing and maintaining social relationships, managing social conflict, and developing skills for adult life. The book concludes with a look at children and how cross-cultural differences in physical and behavioral development can be understood in terms of evolutionary theory. The result is a landmark in primate studies, one that shows how understanding juvenile development yields insight into entire life histories. The book will be of interest to anthropologists, biologists, primatologists, and psychologists.

Life is often a matter of gambles, pay-offs, and trade-offs, just like a game. This book takes readers on a tour through the games and computer simulations that are actually helping to advance knowledge in such fields as ecology, evolution, and animal behavior. Although the book deals with questions of vital importance, like sex and survival, it does so in the lively, entertaining spirit of game-playing. It starts with artificial life and self-replicating automata, a topic ideally suited for a computer-games approach. The book goes on to study pursuit games between predators and prey, and chaotic motion and its role in ecology. Games of chance and statistical paradoxes illuminate the randomness in molecular evolution, while some bizarre double games played by chromosomes help explain the laws of population genetics. Other topics include courtship, ownership, partnership, and brinksmanship--illustrated through the game of poker and computer tournaments. No other book explains so well why scientific observations and insights can be structured as the rules of a survival game, and what happens when they are assembled on a computer or in the mind and allowed to run their course. General readers as well as professionals and students in ecological, evolutionary, and behavioral studies will find this a fascinating and informative work.

Starting with concise species accounts for all the marmoset and tamarin monkeys, this important new book then goes on to review their geographical distributions and still-contested taxonomy, along with comparative reviews of vocalizations, scent-marking, mating systems, infant care and development, social organization, and behaviour and ecology in the wild. As several of these small primates are rare or threatened, these subjects are strongly relevant to their management in captivity as well as for understanding natural populations. This is the first volume for several years to review current knowledge of this family, which comprises 52 species and subspecies found from Panama to northeastern Paraguay to southern Brazil.

Societies develop as a result of the interactions of individuals as they compete and cooperate with one another in the evolutionary struggle to survive and reproduce successfully. Gorilla society is arranged according to these different and sometimes conflicting evolutionary goals of the sexes. In seeking to understand why gorilla society exists as it does, Alexander H. Harcourt and Kelly J. Stewart bring together extensive data on wild gorillas, collected over decades by numerous researchers working in diverse habitats across Africa, to illustrate how the social system of gorillas has evolved and endured.
"Gorilla Society "introduces recent theories explaining primate societies, describes gorilla life history, ecology, and social systems, and explores both sexes' evolutionary strategies of survival and reproduction. With a focus on the future, Harcourt and Stewart conclude with suggestions for future research and conservation. An exemplary work of socioecology from two of the world's best known gorilla biologists, "Gorilla Society" will be a landmark study on a par with the work of George Schaller--a synthesis of existing research on these remarkable animals and the societies in which they live.

The chimpanzee of all other living species is our closest relation, with whom we last shared a common ancestor about five million years ago. These African apes make and use a rich and varied kit of tools, and of the primates they are the only consistent and habitual tool-users and tool-makers. Chimpanzees meet the criteria of a culture as originally defined for human beings by socio-cultural anthropologists. They show sex differences in using tools to obtain and to process a variety of plant and animal foods. The technological gap between chimpanzees and human societies that live by foraging (hunter-gatherers) is surprisingly narrow at least for food-getting. Different communities of wild chimpanzees have different tool-kits and not all of this regional and local variation can be explained by the demands of the physical and biotic environments in which they live. Some differences are likely to be customs based on socially derived and symbolically encoded traditions. This book describes and analyzes the tool-use of humankind's nearest living relation. It focuses on field studies of these apes across Africa, comparing their customs to see if they can justifiably be termed cultural. It makes direct comparisons with the material culture of human foraging peoples. The book evaluates the chimpanzee as an evolutionary model, showing that chimpanzee behavior helps us to infer the origins of technology in human prehistory.

Far from being an abnormal or infrequent activity, cannibalism is a naturally occurring behavior with far-reaching implications for the ecology, life history, and evolution of many species. This book offers the first detailed review of the subject, covering the contextual and taxonomic diversity of cannibalism, and explaining its costs, benefits and taxonomic consequences for a broad distribution of species from lower eukaryotes to higher primates. The authors explore the different varieties of cannibalism, including infanticide, mating and courtship rituals, gerontophagy, oophagy, and competitive interactions. They also assess the ecological and evolutionary causes and effects of cannibalistic behavior, using the theoretical tools successfully applied to the study of foraging behavior, sociality, demography, and genetics. These findings will interest a broad audience of ecologists, evolutionary biologists, and students of animal behavior.
