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.

A fascinating examination of socially parasitic invaders, from butterflies to bacteria, that survive and thrive by exploiting the communication systems of ant colonies. Down below, on sidewalks, in fallen leaves, and across the forest floor, a covert invasion is taking place. Ant colonies, revered and studied for their complex collective behaviors, are being infiltrated by tiny organisms called myrmecophiles. Using incredibly sophisticated tactics, various species of butterflies, beetles, crickets, spiders, fungi, and bacteria insert themselves into ant colonies and decode the colonies' communication system. Once able to "speak the language," these outsiders can masquerade as ants. Suddenly colony members can no longer distinguish friend from foe. Pulitzer Prize-winning author and biologist Bert Hoelldobler and behavioral ecologist Christina L. Kwapich explore this remarkable phenomenon, showing how myrmecophiles manage their feat of code-breaking and go on to exploit colony resources. Some myrmecophiles slip themselves into their hosts' food sharing system, stealing liquid nutrition normally exchanged between ant nestmates. Other intruders use specialized organs and glandular secretions to entice ants or calm their aggression. Guiding readers through key experiments and observations, Hoelldobler and Kwapich reveal a universe of behavioral mechanisms by which myrmecophiles turn ants into unwilling servants. As The Guests of Ants makes clear, symbiosis in ant societies can sometimes be mutualistic, but, in most cases, these foreign intruders exhibit amazingly diverse modes of parasitism. Like other unwelcome guests, many of these myrmecophiles both disrupt and depend on their host, making for an uneasy coexistence that nonetheless plays an important role in the balance of nature.

“These cats are like emissaries from the raw landscapes out West, probing the rest of the nation, showing us where patches of wildness remain, and bring a fuller dimension of wildness to them. It’s as if they’re testing to find out just what folks have in mind when they say they want to preserve natural settings. How natural? How toothy?” -- From the Foreword During a time when most wild animals are experiencing decline in the face of development and climate change, the intrepid mountain lion -- also known as a puma, a cougar, and by many other names – has experienced reinvigoration as well as expansion of territory. What makes this cat, the fourth carnivore in the food chain -- just ahead of humans – so resilient and resourceful? And what can conservationists and wild life managers learn from them about the web of biodiversity that is in desperate need of protection? Their story is fascinating for the lessons it can afford the protection of all species in times of dire challenge and decline. With hands-on experience in both the Rocky Mountains and the wilds of Patagonia in South America, wildlife manager Jim Williams tracks the path of the puma, and in doing so, challenges readers to consider humans’ role in this journey as well as what commitment to nature and conservation means in this day and age.

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.

Practical Feline Behaviour contains all the relevant information that a veterinary nurse or technician needs to understand and handle the behaviour and welfare of house cats, and to offer safe and practical advice to clients. There have been ground-breaking advances in our understanding of feline behaviour in recent years and, to protect the welfare of cats, it is increasingly important that anyone involved with their care, especially those in a professional capacity, keep up to date with these developments. This approachable and down-to-earth text describes the internal and external influences on feline behaviour; on communication, learning, social behaviour, the relationship between behaviour and disease, and the cat - human relationship. It also provides practical advice on how the welfare of cats in our care may be protected and how behaviour problems should be addressed and how to avoid them. In this book Trudi Atkinson draws on her extensive experience as a veterinary nurse and a Certified Clinical Animal Behaviourist to provide a rapid reference and an intensely practical feline behaviour resource for owners, breeders, veterinary professionals, shelter and cattery workers and anyone involved in the care of our feline companions. - Practical, down to earth guide detailing all aspects of feline behaviour - Rapid reference for instant access to information - Written by a well-known animal behaviourist who has extensive experience in treating feline behaviour problems and in advising clients to protect the welfare of their cats - Includes a foreword by John Bradshaw, School of Veterinary Science at University of Bristol, UK

This volume had it's inception in a series of eight lectures delivered at Columbia University during the spring of 1905, and represents, in a much condensed form, the results of a decade of uninterrupted study of the Formicidae, and of the works that have been written on these insects.

The more we learn about bees, the more extraordinary they seem. They have five eyes and beat their wings at almost 200 cycles per second. And to communicate with each other bees do make sounds but also dance. This book, packed with over 30 figures, gives a fascinating insight into the extraordinary complex and highly organised world of bees. The author, K. Weiss, explains the critical role that bees and bee-keeping play for human society, and offers advice for those interested in raising bees.

Crustaceans are increasingly used as model organisms in all fields of biology, including neurobiology, developmental biology, animal physiology, evolutionary ecology, biogeography, and resource management. One reason for the increasing use of crustacean examples is the wide range of phenotypes found in this group and the diversity of environments they inhabit; few other taxa exhibit such a variety of body shapes and adaptations to particular habitats and environmental conditions. A good overview of their functional morphology is essential to understanding many aspects of their biology. This volume is the first in The Natural History of Crustacea series, a ten-volume series that will treat all aspects of crustacean biology, physiology, behavior, and evolution. The series updates and synthesizes a growing wealth of information on the natural history of this remarkable group. Functional Morphology and Diversity explores the functional morphology of crustaceans, which cover the main body parts and systems. The book brings together a group of internationally recognized-and up-and-coming-experts in fields related to systematics and morphology. Contributing authors study a range of crustacean taxa and topics, and thus the volume provides a compact overview of the great phenotypic diversity and their function found among crustaceans. The first broad treatment of Crustacea in decades, the book will be invaluable for researchers and students in this and related fields.

Humans have had a profound influence on the horse since its domestication in the late Neolithic period. Used for transport, labour, food and recreation, horses have become important in many facets of our society. Daniel Mills and Sue McDonnell have produced an exceptional account of our current knowledge of the development and management of the behaviour of the horse, from its wild roots. The Domestic Horse, first published in 2005, brings together, for the first time, an unrivalled collection of international scientific authors to write on the latest findings concerning the behaviour and welfare of this beautiful animal. Illustrated throughout, The Domestic Horse will appeal to animal scientists, those working with horses in a professional capacity and the owner/enthusiast. It also provides sound complementary reading for animal/equine science courses and veterinary students.

How similar are your choices, behaviours, and lifestyle to those of a parrot? We humans are not like other mammals. We look like them, but we don't act like them. In fact, many of our defining human traits: our longevity, intelligence, monogamy and childrearing, and learning and language, all deep parts of what it means to be human, are far more similar to birds than to our fellow mammals. These similarities originate not from shared ancestors but from parallel histories. Our evolutionary stories have pushed humans and birds to the same solutions. In this book, Antone Martinho-Truswell explores these similarities to argue that we can learn a great deal about ourselves by thinking of the human species as 'the bird without feathers'. This is also a book about convergent evolution - evolution that drives very different species to very similar outcomes and behaviours. The traits we share with birds but not mammals are the result of similar, specific pressures that demanded similar solutions - and exploring these similarities can help us understand both why we evolved to be the way we are, and also how very unusual some of our behaviours are in the animal kingdom, Drawing on a rich array of examples across the natural world, Martinho-Truswell also demonstrates the ways in which parrots are our biological mirror image; an evolutionary parallel to ourselves. In contemplating what we share with the birds, and especially the parrots, we understand how close nature came to creating another lineage of radical intelligence on Earth, and we also come to better understand ourselves.
