Baboon Perspectives on Early Human Ancestors brings together the most recent information on the behavior and ecology of Papio baboons and early hominins. Building on a long tradition and integrating recent developments, it discusses the ways that baboon behavior can enhance our understanding of our early ancestors. This approach augments interpretation of the archeological record and provides hypotheses for the gaps in the record and for the millions of years before the record began. Baboon behavior complements the widely used chimpanzee models, but also generates competing hypotheses. Among the many topics covered in the book are foraging and predator defense; multi-level societies and male-female relationships; social and ecological cognition; and communication and the roots of language.

A groundbreaking new perspective on collective behavior across biological systemsCollective behavior is everywhere in nature, from gene transcription and cancer cells to ant colonies and human societies. It operates without central control, using local interactions among participants to allow groups to adjust to changing conditions. The Ecology of Collective Behavior brings together ideas from evolutionary biology, network science, and dynamical systems to present an ecological approach to understanding how the interactions of individuals generate collective outcomes.Deborah Gordon argues that the starting point for explaining how collective behavior works in any natural system is to consider how it changes in relation to the changing world around it. She shows how feedback use—the means by which networks of interactions operate—and the organization of interaction networks evolve to reflect the stability and demands of the environment. Ant colonies function collectively, and the enormous diversity of species in different habitats provides opportunities to look for general ecological patterns. Through an in-depth comparison of ant species, Gordon identifies broad trends in how the diversity of collective behavior in many other collective systems reflects the dynamics of the environment.Shedding light on how individual actions give rise to group behavior, The Ecology of Collective Behavior explains the evolution of collective behavior through innovation in participant interactions, offering new insights into how collective responses function in changing conditions.

NAMED A TOP-TEN BEST BOOK OF 2023 BY SCIENTIFIC AMERICAN A “fascinating” exploration (Elizabeth Kolbert) of how ecosystems are sculpted and sustained by animals eating, pooping, and dying—and how these fundamental functions could help save us from climate catastrophe. If forests are the lungs of the planet, then animals migrating across oceans, streams, and mountains—eating, pooping, and dying along the way—are its heart and arteries, pumping nitrogen and phosphorus from deep-sea gorges up to mountain peaks, from the Arctic to the Caribbean. Without this conveyor belt of crucial, life-sustaining nutrients, the world would look very different. The dynamics that shape our physical world—atmospheric chemistry, geothermal forces, plate tectonics, and erosion through wind and rain—have been explored for decades. But the effects on local ecosystems of less glamorous forces—rotting carcasses and deposited feces—as well as their impact on the global climate cycle, have been largely overlooked. The simple truth is that pooping and peeing are daily rituals for almost all animals, the ellipses of ecology that flow through life. We eat, we poop, and we die. From the volcanoes of Iceland to the tropical waters of Hawaii, the great plains of the American heartland, and beyond, Eat, Poop, Die, “compulsively readable” (Shelby Van Pelt), takes readers on an exhilarating and enlightening global adventure, revealing the remarkable ways in which the most basic biological activities of animals make and remake the world—and how a deeper understanding of these cycles provides us with opportunities to undo the environmental damage humanity has wrought on the planet we call home.

Exploring Animal Behavior in Laboratory and Field, Second Edition provides a comprehensive manual on animal behavior lab activities. This new edition brings together basic research and methods, presenting applications and problem-solving techniques. It provides all the details to successfully run designed activities while also offering flexibility and ease in setup. The exercises in this volume address animal behavior at all levels, describing behavior, theory, application and communication. Each lab provides details on how to successfully run the activity while also offering flexibility to instructors. This is an important resource for students educators, researchers and practitioners who want to explore and study animal behavior. The field of animal behavior has changed dramatically in the past 15 - 20 years, including a greater use and availability of technology and statistical analysis. In addition, animal behavior has taken on a more applied role in the last decade, with a greater emphasis on conservation and applied behavior, hence the necessity for new resources on the topic. Offers an up-to-date representation of animal behavior Examines ethics and approvals for the study of vertebrate animals Includes contributions from a large field of expertise in the Animal Behavior Society Provides a flexible resource that can be used as a laboratory manual or in a flipped classroom setting

Carnivores include some of the most impressive, dangerous and mysterious animals in the world. Hans Kruuk has spent his life studying them against magnificent backdrops, from the Serengeti savannahs and Kalahari deserts to the Scottish Highlands, from the Galápagos Islands to the Far East. In each location he has used meticulous observation of animal behaviour to understand the ecology and natural history of wild carnivore populations, and ultimately to promote their conservation. This book describes the methods, challenges and rewards of the science of behavioural ecology. However, it essentially concerns the personal, rather than the scientific, side of that work, and above all the field experiences involved. With photographs and line drawings, it brings to life African safaris, the hyena in his bath, flights with vultures, dives with otters, attacks by a badger in Scotland and by feral dogs in Galápagos, gull-eating hedgehogs in Britain and the role of animals in African witchcraft. The author communicates his lifelong fascination with wildlife through these unique experiences and the insights they afforded him. Professor Kruuk is a leading authority on animal behaviour and the author of classic studies of hyaenas, otters and badgers, as well as a biography of his Oxford mentor Niko Tinbergen.

This stimulating and comprehensive collection brings together multiple perspectives on the topic of personality in nonhuman animals—linking historical perspectives, theoretical approaches, methods, and cutting-edge discoveries. Experts from various fields describe their findings on species ranging from dogs, cats, chimpanzees, and dolphins to sharks, snakes, and other reptiles. Chapters not only discuss the evolution of personality, but also describe potential applications within the areas of animal-human interactions, animal ethics and welfare, conservation science, and other areas. A key focus is the role of genetics and the environment in determining animal behavior and personality, including related traits, such as creativity and boredom. These chapters present the study of personality in nonhumans as a means by which we can better understand medical and psychological issues specific to our own species as well. Chapters include:· Exploring factor space (and other adventures) with the Hominoid Personality Questionnaire· The quantitative and molecular genetics of individual differences in animal personality· Personality, temperament and individuality in reptile behavior· What do we want to know about personality in marine mammals?· Individual differences in nonhuman animals: examining boredom, curiosity, and creativity· The interplay between animal personality and foraging ecology Taking significant steps in advancing the study of animal personality, Personality in Nonhuman Animals will engage personality psychologists, comparative psychologists, and behavior ecologists as well as conservationists, zookeepers, livestock managers, and all those interested in the brain and behavior of animals.

Animal Vigilance builds on the author's previous publication with Academic Press (Social Predation: How Group Living Benefits Predators and Prey) by developing several other themes including the development and mechanisms underlying vigilance, as well as developing more fully the evolution and function of vigilance. Animal vigilance has been at the forefront of research on animal behavior for many years, but no comprehensive review of this topic has existed. Students of animal behavior have focused on many aspects of animal vigilance, from models of its adaptive value to empirical research in the laboratory and in the field. The vast literature on vigilance is widely dispersed with often little contact between models and empirical work and between researchers focusing on different taxa such as birds and mammals. Animal Vigilance fills this gap in the available material. - Tackles vigilance from all angles, theoretical and empirical, while including the broadest range of species to underscore unifying themes - Discusses several newer developments in the area, such as vigilance copying and effect of food density - Highlights recent challenges to assumptions of traditional models of vigilance, such as the assumption that vigilance is independent among group members, which is reviewed during discussion of synchronization and coordination of vigilance in a group - Written by a top expert in animal vigilance

CURIOUS creatures of Animal Life have been objects of interest to mankind in all ages and countries; the universality of which may be traced to that feeling which'makes the whole world kin.'The Egyptian records bear testimony to a familiarity not only with the forms of a multitude of wild animals, but with their habits and geographical distribution.'The collections of living animals, now popularly known as Zoological Gardens, are of considerable antiquity. We read of such gardens in China as far back as 2,000 years; but they consisted chiefly of some favourite animals, such as stags, fish, and tortoises. The Greeks, under Pericles, introduced peacocks in large numbers from India. The Romans had their elephants; and the first giraffe in Rome, under Cæsar, was as great an event in the history of zoological gardens at its time as the arrival in 1849 of the Hippopotamus was in London. The first zoological garden of which we have any detailed account is that in the reign of the Chinese Emperor, Wen Wang, founded by him about 1150 A.D., and named by him'The Park of Intelligence;'it contained mammalia, birds, fish, and amphibia. The zoological gardens of former times served their masters occasionally as hunting-grounds. This was constantly the case in Persia; and in Germany, so late as 1576, the Emperor Maximilian II. kept such a park for different animals near his castle, Neugebah, in which he frequently chased.Alexander the Great possessed his zoological gardens. We find from Pliny that Alexander had given orders to the keepers to send all the rare and curious animals which died in the gardens to Aristotle. Splendid must have been the zoological gardens which the Spaniards found connected with the Palace of Montezuma. The letters of Ferdinand Cortez and other writings of the time, as well as more recently'The History of the Indians,'by Antonio Herrera, give most interesting and detailed accounts of the menagerie in Montezuma's park. The collections of animals exhibited at fairs have added little to Zoological information; but we may mention that Wombwell, one of the most noted of the showfolk, bought a pair of the first Boa Constrictors imported into England: for these he paid 75l., and in three weeks realised considerably more than that sum by their exhibition. At the time of his death, in 1850, Wombwell was possessed of three huge menageries, the cost of maintaining which averaged at least 35l. per day; and he used to estimate that, from mortality and disease, he had lost, from first to last, from 12,000l. to 15,000l. Our object in the following succession of sketches of the habits and eccentricities of the more striking animals, and their principal claims upon our attention, is to present, in narrative, their leading characteristics, and thus to secure a willing audience from old and young.

The scientific study of networks - computer, social, and biological - has received an enormous amount of interest in recent years. However, the network approach has been applied to the field of animal behaviour relatively late compared to many other biological disciplines. Understanding social network structure is of great importance for biologists since the structural characteristics of any network will affect its constituent members and influence a range of diverse behaviours. These include finding and choosing a sexual partner, developing and maintaining cooperative relationships, and engaging in foraging and anti-predator behavior. This novel text provides an overview of the insights that network analysis has provided into major biological processes, and how it has enhanced our understanding of the social organisation of several important taxonomic groups. It brings together researchers from a wide range of disciplines with the aim of providing both an overview of the power of the network approach for understanding patterns and process in animal populations, as well as outlining how current methodological constraints and challenges can be overcome. Animal Social Networks is principally aimed at graduate level students and researchers in the fields of ecology, zoology, animal behaviour, and evolutionary biology but will also be of interest to social scientists.

Assembles a collection of experts to provide a current account of different approaches (e.g., traditional, comparative and experimental) being applied to study mobility. Moreover, the book aims to stimulate new theoretical perspectives that adopt a holistic view of the interaction among intrinsic (i.e. skeletal) and extrinsic (i.e. environmental) factors that influence differential expression of mobility. Since the environment undoubtedly impacts mobility of a wide variety of animals, insights into human mobility, as a concept, can be improved by extending approaches to investigating comparable environmental influences on mobility in animals in general. The book teases apart environmental effects that transcend typical categories (e.g., coastal versus inland, mountainous versus level, arboreal versus terrestrial). Such an approach, when coupled with a new emphasis on mobility as types of activities rather than activity levels, offers a fresh, insightful perspective on mobility and how it might affect the musculoskeletal system.

Throughout their lives animals must complete many tasks, including finding food, avoiding predators, attracting mates, and navigating through a complex and dynamic environment. Consequently, they have evolved a staggering array of sensory organs that are fundamental to survival and reproduction and shape much of their evolution and behaviour. Sensory ecology deals with how animals acquire, process, and use information in their lives, and the sensory systems involved. It investigates the type of information that is gathered by animals, how it is used in a range of behaviours, and the evolution of such traits. It deals with both mechanistic questions (e.g. how sensory receptors capture information from the environment, and how the physical attributes of the environment affect information transmission) and functional questions (e.g. the adaptive significance of the information used by the animal to make a decision). Recent research has dealt more explicitly with how sensory systems are involved with and even drive evolutionary change, including the formation of new species. Sensory Ecology, Behaviour, and Evolution provides a broad introduction to sensory ecology across a wide range of taxonomic groups, covering all the various sensory modalities (e.g. sound, visual, chemical, magnetic, and electric) relating to diverse areas spanning anti-predator strategies, foraging, mate choice, navigation and more, with the aim being to illustrate key principles and differences. This accessible textbook is suitable for senior undergraduates, graduate students, and professional academics taking courses or conducting research in sensory ecology/biology, neuroethology, behavioural and evolutionary ecology, communication, and signalling. It will also be of relevance and use to psychologists interested in sensory information and behaviour.

Some primate field studies have been on-going for decades, covering significant portions of individual life cycles or even multiple generations. In this volume, leading field workers report on the history and infrastructure of their projects in Madagascar, Africa, Asia and South America. More importantly, they provide summaries of their long-term research efforts on primate behaviour, ecology and life history, highlighting insights that were only possible because of the long-term nature of the study. The chapters of this volume collectively outline the many scientific reasons for studying primate behaviour, ecology and demography over multiple generations. This kind of research is typically necessitated by the relatively slow life histories of primates. Moreover, a complete understanding of social organization and behaviour, factors often influenced by rare but important events, requires long-term data collection. Finally, long-term field projects are also becoming increasingly important foci of local conservation activities.

Begins with in-depth coverage of wildlife behavior concepts as they relate to conservation problems. Topics will focus principally on discussion, critique, and development of behavioral concepts, with particular attention given to published studies on various topics in wildlife behavioral concepts as related to conservation and natural history. He will include an extensive list of references.

This is a book about proximate mechanisms. Although some theoreti­ cal structure is used to introduce the subject, the intent is to offer a comprehensive view of the mechanistic side of searching (or foraging) so as to balance the current emphasis of books on mathematical and functional models. It seems to me that the pendulum needs to swing back to studies of how animals behave, and that maybe in so doing models will become valuable again in driving experimentation. I have probably included too many examples in this book, and some are even presented in great detail. Hopefully, they provide a complete picture of the kind of animals used, the experimental setup, the kinds of data yielded, and how the data were analysed. I have done this in response to frustrating experiences of reading chapters in behavioural ecobgy books that provide insufficient information with which to evaluate an author's conclusion.

In 1987, the University of Chicago Press published Primate Societies, the standard reference in the field of primate behavior for an entire generation of students and scientists. But in the twenty-five years since its publication, new theories and research techniques for studying the Primate order have been developed, debated, and tested, forcing scientists to revise their understanding of our closest living relatives. Intended as a sequel to Primate Societies, The Evolution of Primate Societies compiles thirty-one chapters that review the current state of knowledge regarding the behavior of nonhuman primates. Chapters are written by the leading authorities in the field and organized around four major adaptive problems primates face as they strive to grow, maintain themselves, and reproduce in the wild. The inclusion of chapters on the behavior of humans at the end of each major section represents one particularly novel aspect of the book, and it will remind readers what we can learn about ourselves through research on nonhuman primates. The final section highlights some of the innovative and cutting-edge research designed to reveal the similarities and differences between nonhuman and human primate cognition. The Evolution of Primate Societies will be every bit the landmark publication its predecessor has been.

Human-induced environmental change currently represents the single greatest threat to global biodiversity. Species are typically adapted to the local environmental conditions in which they have evolved. Changes in environmental conditions initially influence behaviour, which in turn affects species interactions, population dynamics, evolutionary processes and, ultimately, biodiversity. How animals respond to changed conditions, and how this influences population viability, is an area of growing research interest. Yet, despite the vital links between environmental change, behaviour, and population dynamics, surprisingly little has been done to bridge these areas of research. Behavioural Responses to a Changing World is the first book of its kind devoted to understanding behavioural responses to environmental change. The volume is comprehensive in scope, discussing impacts on both the mechanisms underlying behavioural processes, as well as the longer-term ecological and evolutionary consequences. Drawing on international experts from across the globe, the book covers topics as diverse as endocrine disruption, learning, reproduction, migration, species interactions, and evolutionary rescue.

The study of animal behaviour is one of the fastest growing sub-disciplines in biology. The resulting diversity of conceptual approaches and methodological innovations makes it increasingly difficult for professionals and students to keep abreast of important new developments. This edited volume provides up-to-date reviews that facilitate orientation in key areas of animal behaviour, including communication, cognition, conflict, cooperation, sexual selection and behavioural variation. The contributions address evolutionary and proximate aspects of behaviour and also cover both invertebrates and vertebrates. Important concepts are dealt with in separate glossaries and key examples highlighted in separate text boxes. Richly illustrated with colour figures, this volume offers a well structured overview of all the main developments in current animal behaviour research. It is ideal for teaching upper-level courses, where it will be essential reading for advanced students familiar with basic concepts and ideas.

This will be the first time a volume will be compiled focusing on South American monkeys as models to address and test critical issues in the study of nonhuman primates. In addition, the volume will serve an important compliment to the book on Mesoamerican primates recently published in the series under the DIPR book series. The book will be of interest to a broad range of scientists in various disciplines, ranging from primatology, to animal behavior, animal ecology, conservation biology, veterinary science, animal husbandry, anthropology, and natural resource management. Moreover, although the volume will highlight South American primates, chapters will not simply review particular taxa or topics. Rather the focus of each chapter is to examine the nature and range of primate responses to changes in their ecological and social environments, and to use data on South American monkeys to address critical theoretical questions in the study of primate behavior, ecology, and conservation. Thus, we anticipate that the volume will be widely read by a broad range of students and researchers interested in prosimians, New World monkeys, Old World monkeys, apes, humans, as well as animal behavior and tropical biology.

Since the 1960s, primatologists have recognized the impact of predation on the evolution of morphology, the social systems and cognitive behavior of monkeys and apes, but few studies considered its impact on the prosimians - lemurs, lorises, galagos and tarsiers. This comprehensive volume, written by experts in the field, narrows this gap by highlighting the effect of predation on the order Primates in general. Theoretical approaches to understanding how primates perceive predation threat, as well as proximate and ultimate causes to address threat and attack, are considered across the primate order. Although this volume concentrates on the least known group in this theoretical area - the prosimians - contributions by researchers on numerous primate taxa across four major geographical regions make this a novel and exciting contribution to students interested in primate evolution and ecology.

Our knowledge of extinct animals depends almost entirely upon the study of fossils. This richly illustrated book clothes the skeletons of dinosaurs and other Mesozoic reptiles with flesh, and shows how these fascinating animals evolved and probably lived. Expert author John L. Cloudsley-Thompson provides an interesting synthesis of current views on their ecology, physiology and behaviour, and outlines the various hypotheses that have been proposed to explain their extinction. Numerous beautiful drawings of the animals and their environment illustrate this exciting monograph.

Numerous figures, illustrations, and tables; integration of new literature and concepts into field of primatology; emphasis upon both behavioral and cognitive mechanisms.

Exploring Animal Behavior in Laboratory and Field is designed to provide a variety of exercises that engage students actively in all phases of scientific investigation, from formulating research questions through interpreting and presenting final results. It attempts to share the collective teaching expertise and experience of members of the Animal Behavior Society with all who are willing to benefit from their wisdom. Four types of exercises are presented: (1) traditional exercises in which students follow a pre-determined protocol to test particular hypotheses explicitly stated in the exercise, (2) traditional exercises that can easily be adapted to inquiry-based approaches, (3) combined pedagogy exercises that involve both traditional and inquiry approaches, and (4) inquiry exercises in which students first brainstorm to generate their own hypotheses, then design their own experiements to test their hypotheses.• Supports a range of pedagogical styles and texts in animal behavior with active learning experiences that engage students• Students and instructors benefit from knowledge and experience of members of the Animal Behavior Society• Flexibility of design enables students and instrucotrs to tailor the exercises to their needs • Can be used to support lab courses that are completely inquiry based as well as independent student research projects in animal behavior• Consideration of animal care guidelines provides an excellent way to address and discuss concerns about the use of animals in teaching and research• Emphasizes the hypothetico-deductive approach that students have difficulty understanding and implementing• Supporting materials make additional required texts unnecessary and link study design considerations with real studies

P. Berthold and E. Gwinnd Bird migration is an intriguing aspect of the living world - so much so that it has been investigated for as long, and as thoroughly, as almost any other natural phenomenon. Aristotle, who can count as the founder of scientific ornithology, paid very close attention to the migrations of the birds he ob­ served, but it was not until the reign of Friedrich II, in the first half of the 13th century, that reliable data began to be obtained. From then on, the data­ base grew rapidly. Systematic studies of bird migration were introduced when the Vogelwarte Rossitten was founded, as the first ornithological­ biological observation station in the world (see first chapter'In Memory of Vogelwarte Rossitten'). This area later received enormous impetus when ex­ perimental research on the subject was begun: the large-scale bird-ringing experiment initiated in Rossitten in 1903 by Johannes Thienemann (who was inspired by the pioneering studies of C. C. M. Mortensen), the experiments on photoperiodicity carried out by William Rowan in the 1920s in Canada and retention and release experiments performed by Thienemann in the 1930s in Rossitten, the first experimental study on the orientation of migratory birds. After the Second World War, migration research, while continuing in the previous areas, also expanded into new directions such as radar ornithology, ecophysiology and hormonal control mechanisms, studies of evolution, ge­ netics, telemetry and others.

When a parasite invades an ant, does the ant behave like other ants? Maybe not-and if it doesn't, who, if anyone, benefits from the altered behaviors? The parasite? The ant? Parasites and the Behavior of Animals shows that parasite-induced behavioral alterations are more common than we might realize, and it places these alterations in an evolutionary and ecological context. Emphasizing eukaryotic parasites, the book examines the adaptive nature of behavioral changes associated with parasitism, exploring the effects of these changes on parasite transmission, parasite avoidance, and the fitness of both host and parasite. The behavioral changes and their effects are not always straightforward. To the extent that virulence, for instance, is linked to parasite transmission, the evolutionary interests of parasite and host will diverge, and the current winner of the contest to maximize reproductive rates may not be clear, or, for that matter, inevitable. Nonetheless, by affecting susceptibility, host/parasite lifespan and fecundity, and transmission itself, host behavior influences parameters that are basic to our comprehension of how parasites invade host populations, and fundamentally, how parasites evolve. Such an understanding is important for a wide range of scientists, from ecologists and parasitologists to evolutionary, conservation and behavioral biologists: The behavioral alterations that parasites induce can subtly and profoundly affect the distribution and abundance of animals.

In this pathbreaking and far-reaching work George Oster and Edward Wilson provide the first fully developed theory of caste evolution among the social insects. Furthermore, in studying the effects of natural selection in generally increasing the insects'ergonomic efficiency, they go beyond the concentration of previous researchers on the physiological mechanisms of the insects and turn our attention instead to the scale and efficiency of the insects'division of labor.Recognizing that the efficiency of the insect colony is based on a complex fitting of the division of labor to many simultaneous needs, including those imposed by the distribution of resources and enemies around the nest, Professors Oster and Wilson are able to construct a series of mathematical models to characterize the agents of natural selection that promote particular caste systems.The social insects play a key role in the subject of sociobiology because their social organization is so rigid and can be related to genetic evolution. Because of this important consideration, the authors'work has consequences not only for entomology but also for general evolutionary theory.

What is the minimum dimension of a niche space necessary to represent the overlaps among observed niches? This book presents a new technique for obtaining a partial answer to this elementary question about niche space. The author bases his technique on a relation between the combinatorial structure of food webs and the mathematical theory of interval graphs. Professor Cohen collects more than thirty food webs from the ecological literature and analyzes their statistical and combinatorial properties in detail. As a result, he is able to generalize: within habitats of a certain limited physical and temporal heterogeneity, the overlaps among niches, along their trophic (feeding) dimensions, can be represented in a one-dimensional niche space far more often than would be expected by chance alone and perhaps always. This compatibility has not previously been noticed. It indicates that real food webs fall in a small subset of the mathematically possible food webs. Professor Cohen discusses other apparently new features of real food webs, including the constant ratio of the number of kinds of prey to the number of kinds of predators in food webs that describe a community. In conclusion he discusses possible extensions and limitations of his results and suggests directions for future research.

Advances in the Study of Behavior continues to serve scientists across a wide spectrum of disciplines. Focusing on new theories and research developments with respect to behavioral ecology, evolutionary biology, and comparative psychology, these volumes foster cooperation and communication in these diverse fields.

Advances in the Study of Behavior is the leading series in its field. Each volume includes a variety of review essays by experts providing authoritative overviews of key areas of current interest that are invaluable to the teacher, student, and researcher in the field of behavior, whether psychologist or biologist. This volume continues the tradition of excellence in the study of behavior by covering a whole range of biological and psychological research. Each of the chapters presents new ideas, with a particularly interesting approach to sexual coercion. The volume as a whole has a particular strength in the area of behavioral development, which is the main topic of the last three chapters.

Advances in the Study of Behavior continues to serve scientists across a wide spectrum of disciplines. Focusing on new theories and research developments with respect to behavioral ecology, evolutionary biology, and comparative psychology, these volumes serve to foster cooperation and communication in these diverse fields. Volume 23 focuses on research on the lower vertebrates with respect to the functional significance of different breeding strategies, the level at which natural selection acts, methods of teasing apart the genetic control of behavior, the assumptions underlying models of territoriality, and signalling systems and the sensory mechanisms on which they depend.

Leading researchers in behavioural ecology discuss specific aspects of this important topic including: The mechanism of habitat selection and how it operates Its relevance to population biology Behavioural and physiological implications The ecological and evolutionary significance of habitat choice and survival and reproduction in various habitat types.

In just the last few years, behavioral ecologists have begun to address issues in conservation biology. This volume is the first attempt to link these disciplines formally. Here leading researchers explore current topics in conservation biology and discuss how behavioral ecology can contribute to a greater understanding of conservation problems and conservation intervention programs. In each chapter, the authors identify a conservation issue, review the ways it has been addressed, review behavioral ecological data related to it, including their own, evaluate the strengths and weaknesses of the behavioral ecological approach, and put forward specific conservation recommendations. The chapters juxtapose different studies on a wide variety of taxonomic groups. A number of common themes emerge, including the ways in which animal mating systems affect population persistence, the roles of dispersal and inbreeding avoidance for topics such as reserve design and effective population size, the key role of humans in conservation issues, and the importance of baseline data for conservation monitoring and modeling attempts. Each chapter sheds new light on conservation problems, generates innovative avenues of interdisciplinary research, and shows how conservation-minded behavioral ecologists can apply their expertise to some of the most important questions we face today.
