This volume presents ecological consequences and evolutionary mechanisms that may be associated with behavioral alterations in parasitized hosts. Alterations may result from natural selection favoring the host or parasite, or there may be side effects of physiological changes associated with symbiosis. This book summarizes the literature in this area, showing that reports of alteration may frequently be consistent with more than one evolutionary explanation and that rigorous tests are needed before the phenomenon can be understood and placed in a predictive framework. Such understanding is important, because these behavioral alterations have been shown to have the potential to affect the distribution of animals in nature and their interactions with predators and competitors, and the alterations may have implications for vector biology.

This text unifies conceptual and empirical advances in evolutionary ecology and provides a volume that can be used as a primary textbook or supplementary reading in an advanced undergraduate or graduate course. The focus is on current concepts in evolutionary ecology and the empirical study of these concepts. Chapters are written by prominent biologists who have made significant contributions to this field and both synthesize the current state of knowledge and identify areas for future investigation. It is divided into five major sections: an overview of the major topics in evolutionary biology for ecologists, and sections on life histories, behaviour, co-evolution, and adaptation to athropogenic change.

Insects that are the least bit social may gather in modest groups, like the dozen or so sawfly larvae feeding on a pine needle, or they may form huge masses, like a swarm of migratory locusts in Africa or a cloud of mayflies at the edge of a midwestern lake or river. Why these insects get together and what they get out of their associations are questions finely and fully considered in this learned and entertaining look at the group behavior and social lives of a wide array of bugs. The groups that Gilbert Waldbauer discusses here are not as complex or tightly organized as the better-known societies of termites, wasps, ants, and bees. Some, like the mayflies, come together merely because they emerge from the water in the same place at the same time. But others, like swarms of locusts, are loosely organized, the individual insects congregating to migrate together for distances of hundreds of miles. And yet others form a simple cooperative society, such as the colony of tent caterpillars that weaves a silken tent to house the whole group. Waldbauer tells us how individuals in these and other insect aggregations communicate (or don't), how they coordinate their efforts, how some congregate the better to mate, how some groups improve the temperature and humidity of their microenvironment, and how others safeguard themselves (or the future of their kind) by amassing in such vast numbers as to confound predators. As engaging and authoritative as Waldbauer's previous books, Millions of Monarchs, Bunches of Beetles will enlighten and delight those who know their insects well and those who wish to know them better.

The ability of species to migrate has interested ecologists for many years. Now that so many species and ecosystems face major environmental change, the ability of species to adapt to these changes by dispersing, migrating, or moving between different patches of habitat can be crucial to ensuring their survival. This book provides a timely and wide-ranging overview of the study of dispersal and incorporates much of the latest research. The causes, mechanisms, and consequences of dispersal at the individual, population, species and community levels are considered. The potential of new techniques and models for studying dispersal, drawn from molecular biology and demography, is also explored. Perspectives and insights are offered from the fields of evolution, conservation biology and genetics. Throughout the book, theoretical approaches are combined with empirical data, and care has been taken to include examples from as wide a range of species as possible.

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.

Urban Evolutionary Biology fills an important knowledge gap on wild organismal evolution in the urban environment, whilst offering a novel exploration of the fast-growing new field of evolutionary research. The growing rate of urbanization and the maturation of urban study systems worldwide means interest in the urban environment as an agent of evolutionary change is rapidly increasing. We are presently witnessing the emergence of a new field of research in evolutionary biology. Despite its rapid global expansion, the urban environment has until now been a largely neglected study site among evolutionary biologists. With its conspicuously altered ecological dynamics, it stands in stark contrast to the natural environments traditionally used as cornerstones for evolutionary ecology research. Urbanization can offer a great range of new opportunities to test for rapid evolutionary processes as a consequence of human activity, both because of replicate contexts for hypothesis testing, but also because cities are characterized by an array of easily quantifiable environmental axes of variation and thus testable agents of selection. Thanks to a wide possible breadth of inference (in terms of taxa) that may be studied, and a great variety of analytical methods, urban evolution has the potential to stand at a fascinating multi-disciplinary crossroad, enriching the field of evolutionary biology with emergent yet incredibly potent new research themes where the urban habitat is key. Urban Evolutionary Biology is an advanced textbook suitable for graduate level students as well as professional researchers studying the genetics, evolutionary biology, and ecology of urban environments. It is also highly relevant to urban ecologists and urban wildlife practitioners.

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.

Whether you have a vested interest in protecting your pets and livestock or are simply spellbound by wild predators, this is the book for you!

“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.
