Harriers are a world-wide group of birds of prey whose mating systems, population dynamics, and evolution are well-studied. This is the first book to synthesise and analyse the masses of data on the behavioural ecology of harriers. It offers an intriguing comparison of breeding systems among harriers in the northern and southern hemispheres, and includes a new phylogeny of the harriers, based on the most recent DNA findings. It is illustrated throughout with original line drawings of these impressive birds.

Game theory has revolutionized the study of animal behavior. The fundamental principle of evolutionary game theory--that the strategy adopted by one individual depends on the strategies exhibited by others--has proven a powerful tool in uncovering the forces shaping otherwise mysterious behaviors. In this volume, the first since 1982 devoted to evolutionary game theory, leading researchers describe applications of the theory to diverse types of behavior, providing an overview of recent discoveries and a synthesis of current research. The volume begins with a clear introduction to game theory and its explanatory scope. This is followed by a series of chapters on the use of game theory to understand a range of behaviors: social foraging, cooperation, animal contests, communication, reproductive skew and nepotism within groups, sibling rivalry, alternative life-histories, habitat selection, trophic-level interactions, learning, and human social behavior. In addition, the volume includes a discussion of the relations among game theory, optimality, and quantitative genetics, and an assessment of the overall utility of game theory to the study of social behavior. Presented in a manner accessible to anyone interested in animal behavior but not necessarily trained in the mathematics of game theory, the book is intended for a wide audience of undergraduates, graduate students, and professional biologists pursuing the evolutionary analysis of animal behavior.

In The Handicap Principle, Amotz and Avishag Zahavi offer a unifying theory that brilliantly explains many previously baffling aspects of animal signalling and holds up a mirror in which ordinary human behaviours take on surprising new significance.

Our understanding of the way in which animals know how, when, and where to orient and navigate around their environment has grown considerably over the last decade. Movement can vary from displacement in the immediate environment to the long-distance migration of salmon or swallows. How animals find their way around is both immensely variable and controversial - what cues they use and how their senses are involved, how much they remember, to what extent they rely on instinctive information or learning. Behaviour, ecology, and neurophysiology are all implicated and have been investigated in a wide range of organisms by researchers all over the world. Individual authors, all eminent specialists within their fields, have been asked to present reviews of the material in which they are most familiar and to speculate about future directions in the field.

Obligatory brood parasites are birds that reproduce by laying their eggs in the nests of other species. This book discusses the ecological and evolutionary aspects of this remarkable behavioural adaptation.

In pairs, male and female birds appear to work as a team, competing for food, defending nests, and protecting predators, but in fact, because each individual strives to maximize its own reproductive potential, conflicts can occur if one finds a better partner. So while some birds choose one mate for life, others have many partners. In this book, fourteen classic studies of bird behavior are brought together to compare the different partnership patterns from ecological and evolutionary perspectives. Particular attention is paid to the availability of mates, the selection process and the consequences of choosing one mate over another. By comparing between and within species, each chapter outlines the features that influence a pair's reproductive performance and how this interacts with ecological and environmental constraints. Introductory and concluding chapters review the latest thinking on this fascinating subject. The book is aimed at students and researchers in behavioral ecology but can also foster new insights for bird watchers and ornithologists.

This book is a personal history and apology, written by one of this century's most distinguished small mammal ecologists, for a life in science spent working on problems for which no final dramatic conclusion was reached. Included along the way are some important anedcotes and history about Charles Elton and the pioneering work at the Bureau of Animal Population at Oxford University, from which much of modern population ecology has grown, and insights on the philosophy and practice of science.

This book is about the genetics and behaviour of individuals within colonies of social insects - bees, wasps, ants, and termites. Colonial living is characterized by division of labour and finely coordinated organization, by reproductive function being limited to certain individuals, by cooperative brood care, and by the presence of non-reproductive workers. Within a colony, however, may events are the result of conflicts between individuals seeking to maximize their own interests. Crozier and Pamilo's contribution is to analyse the genetic bases of the patterns of reproduction and resource allocation found in social insect colonies. This is done more comprehensively and with greater depth and insight than in any previous study, and is a significant step forward in the fields of population genetics and social evolution. This book is intended for researchers and advanced students in population genetics, ecology, evolution, animal behaviour, and entomology.

Population dynamics and animal behaviour are two subjects which have developed almost independently, despite widespread acceptance of the idea that they must be related. This book provides a novel framework for combining these two subjects and then shows how to consider a range of conservation issues. It is aimed at students and researchers in animal behaviour, population ecology, and conservation biology.

This book brings together the results from one of the most significant long-term studies of birds in the late twentieth century, testing our understanding of evolution in natural populations. Combining genetics, behaviour, ecology, and a landmark data set, it will be essential reading for everyone with an interest in evolutionary ecology. The Lesser Snow Goose is a migratory Arctic breeder which occurs in two genetically distinct forms. Most have white plumage, but some are dark, allowing rapid scoring and study of a highly visible heritable trait. Initial chapters describe the natural history, recent evolutionary history, and current patterns of gene flow in the species. A subsequent chapter presents a detailed demographic model integrating both fecundity and survival components of fitness, which is used as an analytical framework throughout later chapters. Two chapters detail the effects of annual and age-specific variation in fitness components. The authors then focus on the microevolutionary status of the population, using data gathered over 26 years on 40,000 individually marked adult geese, 45,000 nests, and 110,000 goslings at one colony in northern Manitoba. The heart of the book analyses the working of natural selection on plumage colour, seasonal timing of breeding, clutch size, egg size, and body size, using the components of fitness approach to quantifying selection in stages throughout the animal life cycle. The results are an important advance in understanding the evolutionary process in vertebrates.

The main theme of Sexual Selection and the Barn Swallow is that sexual selection is important and affects many aspects of animal life such as mating behaviour, parental care, host-parasite interactions, and migration strategies. Birds with extravagant feather ornaments are the standard example of sexual selection. Here the selective advantages of a long tail are investigated for a common bird, the barn swallow, in the context of sexual selection theory. This study constitutes a major empirical test of the theoretical predictions and will be of especial interest to students of behavioural and evolutionary ecology.

At first sight just a small brown bird, the dunnock's unobtrusive appearance belies its extraordinary behaviour and mating patterns. In this book Nick Davies gives a full account of the mating systems of the dunnock or hedge sparrow, Prunella modularis, which include pairs, a male with two females, two males with one female, and several males with several females. Detailed observations, elegant field experiments, and DNA fingerprinting are combined to show how this variable social organization from selfish individuals competing to maximize their own reproductive success. Further experiments reveal how the cuckoo may thwart the dunnock's parental efforts. David Quinn's exquisite drawings provide a visual summary of the birds' behaviour. All students of ecology, evolution, and animal behaviour will want to be familiar with this work, which addresses the wider issues of the influence of ecology on mating systems and the evolutionary significance of conflict within and between species. This is the third volume in the Oxford Series in Ecology and Evolution, and the first in this series to tackly behavioural ecology. Nick Davies is a Lecturer in Zoology at the University of Cambridge and co-editor with J. R. Krebs of the leading text in the field, Behavioural ecology: an evolutionary approach.

This book explores the role of aggression in primate social systems and its implications for human behavior. Many people look to primate studies to see if and how we might be able to predict violent behavior in humans, or ultimately to control war. Of particular interest in the study of primate aggression are questions such as: how do primates use aggression to maintain social organization; what are the costs of aggression; why do some primates avoid aggressive behavior altogether. Students and researchers in primatology, behavioral biology, anthropology, and psychology will read with interest as the editors and contributors to this book address these and other basic research questions about aggression. They bring new information to the topic as well as an integrated view of aggression that combines important evolutionary considerations with developmental, sociological and cultural perspectives.

Discover this remarkable account of twenty-one years in remote Kenya with a troop of Savannah baboons from the New York Times bestselling author of Behave. 'One of the best scientist-writers of our time' Oliver Sacks Brooklyn-born Robert Sapolsky grew up wishing he could live in the primate diorama in the Museum of Natural History. At school he wrote fan letters to primatologists and even taught himself Swahili, all with the hope of one day joining his primate brethren in Africa. But when, at the age of twenty-one, Sapolky's dream finally comes true he discovers that the African bush bears little resemblance to the tranquillity of a museum. This is the story of the next twenty-one years as Sapolsky slowly infiltrates and befriends a troop of Savannah baboons. Alone in the middle of the Serengeti with no electricity, running water or telephone, and surviving countless scams, culinary atrocities and a surreal kidnapping, Sapolsky becomes ever more enamoured with his adopted baboon troop - unique and compelling characters in their own right - and he returns to them summer after summer, until tragedy finally prevails. 'A Primate's Memoir is the closest the baboon is likely to come - and it's plenty close enough - to having its own Iliad' New York Times Review of Books Exhilarating, hilarious and poignant, A Primate's Memoir is a uniquely honest window into the coming-of-age of one of our greatest scientific minds.

While there have been controversial attempts to link conclusions from sociobiological studies of animal populations to humans, few behavioral scientists or anthropologists have made serious progress. In this work, Austin Hughes presents a unique and well-defined theoretical approach to human social behavior that is rooted in evolutionary biology and sociobiology, and which is additionally viewed as a direct continuation of the structural-functional tradition in anthropological research. Using mathematical and statistical techniques, Hughes applies the principles of kin selection theory--which states that natural selection can favor social acts that increase the fitness of both individuals and their relatives--to anthropological data. Among the topics covered are the subdivision of kin groups, selection of leaders in traditional societies, patronage systems, and the correspondence between social and biological kinship. The author concludes that patterns of concentration of relatedness are more important than average relatedness for predicting social behavior. He also shows that social interactions can often be predicted on the basis of common genetic interest in dependent offspring. The result is a major contribution to the field of behavioral biology.

From the shell wars of hermit crabs to little blue penguins spying on potential rivals, power struggles in the animal kingdom are as diverse as they are fascinating, and this book illuminates their surprising range and connections. The quest for power in animals is so much richer, so much more nuanced than who wins what knock-down, drag-out fight. Indeed, power struggles among animals often look more like an opera than a boxing match. Tracing the path to power for over thirty different species on six continents, writer and behavioral ecologist Lee Alan Dugatkin takes us on a journey around the globe, shepherded by leading researchers who have discovered that in everything from hyenas to dolphins, bonobos to field mice, cichlid fish to cuttlefish, copperhead snakes to ravens, and meerkats to mongooses, power revolves around spying, deception, manipulation, forming alliances, breaking up alliances, complex assessments of potential opponents, building social networks, and more. Power pervades every aspect of the social life of animals: what they eat, where they eat, where they live, who they mate with, how many offspring they produce, who they join forces with, and who they work to depose. In some species, power can even change an animal's sex. Nor are humans invulnerable to this magnificently intricate melodrama: Dugatkin's tales of the researchers studying power in animals are full of unexpected pitfalls, twists and turns, serendipity, and the pure joy of scientific discovery.

Wolves are charismatic emblems of wilderness. Dogs, which descended from wolves, are models of urbanity. Do free-ranging dogs revert to pack living or are their societies only reminiscent of a wolfish heritage? Focusing on behavioral ecology, this is the first book to assess societies of both gray wolves and domestic dogs living as urban strays and in the feral state. It provides a comprehensive review of wolf genetics, particularly of New World wolves and their mixture of wolf, coyote and dog genomes. Spotte draws on the latest scientific findings across the specialized fields of genetics, sensory biology, reproductive physiology, space use, foraging ecology and socialization. This interdisciplinary approach provides a solid foundation for a startling and original comparison of the social lives of wolves and free-ranging dogs. Supplementary material, including a full glossary of terms, is available online at www.cambridge.org/9781107015197.

When Charles Darwin first proposed Sexual Selection Theory, he suggested two mechanisms: competition among males and choice by females. Although their importance is long established and extremely well understood, their mirror images have remained largely underappreciated; males also choose, and females also compete. The combination of male mate choice (MMC) and female competition (FC) may be one of the most overlooked yet important and intriguing phenomena in modern sexual selection theory. This novel text reviews our current understanding of MMC and FC, highlighting the important connections between them. It places both concepts in the context of related fields such as female choice, mating systems, and sexual selection theory more broadly. A truly holistic approach is provided which takes all the relevant elements into consideration, especially the relative roles of MMC and FC, female ornamentation, their evolutionary consequences, and their genetic basis. Considering male mate choice and female competition in this way as effectively two sides of the same coin creates a powerful paradigm for a more complete understanding of sexual selection. Male Choice, Female Competition, and Female Ornaments in Sexual Selection is suitable for both graduate students and researchers interested in sexual selection from an evolutionary, psychological, and anthropological perspective. It will also appeal to a broader audience of behavioural ecologists and evolutionary psychologists.

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.

Would you ask a honeybee to point at a screen and recognise a facial expression? Or ask an elephant to climb a tree? While humans and non-human species may inhabit the same world, it's likely that our perceptual worlds differ significantly. Emphasising Uexkull's concept of 'umwelt', this volume offers practical advice on how animal cognition can be successfully tested while avoiding anthropomorphic conclusions. The chapters describe the capabilities of a range of animals - from ants, to lizards to chimpanzees - revealing how to successfully investigate animal cognition across a variety of taxa. The book features contributions from leading cognition researchers, each offering a series of examples and practical tips drawn from their own experience. Together, the authors synthesise information on current field and laboratory methods, providing researchers and graduate students with methodological advice on how to formulate research questions, design experiments and adapt studies to different taxa.

Strategies and Tactics of Behavioral Research and Practice focuses on the most effective methods for measuring and evaluating changes in behavior. The authors provide the rationale for different procedures for measuring behavior and designing within-subject comparisons between control and intervention conditions. The text explains the strengths and weaknesses of methodological alternatives for every topic so that behavioral researchers and practitioners can make the best decisions in each situation. This classic text has been extensively revised to be more accessible and practical. Not only does it feature much more discussion of how research methods are relevant to today's practitioners, it also includes additional examples based on field research and service delivery scenarios. With expanded coverage on creating experimental designs, as well as new chapters on behavioral assessment, the statistical analysis of data, and ethical issues associated with research methods, this book provides a strong foundation for direct behavioral measurement, within-subject research design, and interpretation of behavioral interventions. Enriched with more pedagogical features, including key terms, tables summarizing important points, figures to help readers visualize text, and updated examples and suggested readings, this book is an invaluable resource for students taking courses in research methods. This book is appropriate for researchers and practitioners in behavior analysis, psychology, education, social work, and other social and health science programs that address questions about behavior in research or practice settings.

Ask anyone who has owned a pet and they'll assure you that, yes, animals have personalities. And science is beginning to agree. Researchers have demonstrated that both domesticated and non domesticated animals - from invertebrates to monkeys and apes - behave in consistently different ways, meeting the criteria for what many define as personality. But why the differences, and how are personalities shaped by genes and environment? How did they evolve? The essays in "Animal Personalities" reveal that there is much to learn from our furred and feathered friends. The study of animal personality is one of the fastest-growing areas of research in behavioral and evolutionary biology. Here Claudio Carere and Dario Maestripieri, along with a host of scholars from fields as diverse as ecology, genetics, endocrinology, neuroscience, and psychology, provide a comprehensive overview of the current research on animal personality. Grouped into thematic sections, chapters approach the topic with empirical and theoretical material and show that to fully understand why personality exists, we must consider the evolutionary processes that give rise to personality, the ecological correlates of personality differences, and the physiological mechanisms underlying personality variation.

Essential Ornithology provides the reader with a concise but comprehensive introduction to the biology of birds, one of the most widely studied taxonomic groups.
