Just over one hundred and thirty years ago Charles Darwin, in The Descent of Man and Selection in Relation to Sex (1871), developed remarkably accurate conclusions about man's ancestry, based on a review of general comparative anatomy and psychology in which he regarded sexual selection as a necessary part of the evolutionary process. But the attention of biologists turned to the more general concept of natural selection, in which sexual selection plays a complex role that has been little understood. This volume significantly broadens the scope of modern evolutionary biology by looking at this important and long neglected concept of great importance.

In this book, which is the first full discussion of sexual selection since 1871, leading biologists bring modern genetic theory and behavior observation to bear on the subject. The distinguished authors consider many aspects of sexual selection in many species, including man, within the context of contemporary evolutionary theory and research. The result is a remarkably original and well-rounded view of the whole concept that will be invaluable especially to students of evolution and human sexual behavior. The lucid authority of the contributors and the importance of the topic will interest all who share in man's perennial fascination with his own history.

The book will be of central importance to a wide variety of professionals, including biologists, anthropologists, and geneticists. It will be an invaluable supplementary text for courses in vertebrate biology, theory of evolution, genetics, and physical anthropology. It is especially important with the emergence of alternative explanations of human development, under the rubric of creationism and doctrines of intelligent design.

Prior to publication the study of animal coloration was plagued by fanciful speculations, post hoc explanations and untestable hypotheses. This title, originally published in 1979, draws together widely scattered research into the coloration of animals; formulates predictive hypotheses to account for color; documents the accuracy of many of these hypotheses; and suggests directions for future research. The book grew out of a symposium, The Behavioral Significance of Color at the 1977 meeting of the Animal Behavior Society, and presents evidence concerning patterns of coloration and their influence on animal behaviour and interaction Physical principles of radiation are discussed in Chapter 1, followed, in subsequent chapters, by an examination of the physiological functions of animal coloration (e.g. thermoregulation, hydroregulation, abrasion-resistance, extraretinal photoreception). Treatment of coloration that affects the animal's visibility to other animals opens with a masterful overview of theories of color vision and its occurrence throughout the animal kingdom. Chapter 6 explores the role of color vision and fruit color in the selection of food by wild primates with comments on the coevolution of fruiting trees and their primate customers. Dr Jack P. Hailman addresses the elusive concept of conspicuousness. He summarizes a strategy for calculating conspicuous coloration based on measurements in natural habitats. Experiments, naturalistic observations and anecdotes of optical communication are exceedingly numerous. Chapters 8 and 9 review these data and suggest general principles of inter- and intraspecific optical communication. Each chapter is enhanced by the critical evaluations of Drs. C. Richard Tracy and W. J. Hamilton III. In closing, the editor discusses coloration as it affects an animal's own vision (e.g., black eyelines to reduce glare). Most significantly the book emphasizes the need for a balanced, scientifically rigorous approach to the question of evolution of animal coloration. It is an important source for anyone contemplating or currently involved in research in this field of investigation.

Walk near woods or water on any spring or summer night and you will hear a bewildering (and sometimes deafening) chorus of frog, toad, and insect calls. How are these calls produced? What messages are encoded within the sounds, and how do their intended recipients receive and decode these signals? How does acoustic communication affect and reflect behavioral and evolutionary factors such as sexual selection and predator avoidance?
H. Carl Gerhardt and Franz Huber address these questions among many others, drawing on research from bioacoustics, behavior, neurobiology, and evolutionary biology to present the first integrated approach to the study of acoustic communication in insects and anurans. They highlight both the common solutions that these very different groups have evolved to shared challenges, such as small size, ectothermy (cold-bloodedness), and noisy environments, as well as the divergences that reflect the many differences in evolutionary history between the groups. Throughout the book Gerhardt and Huber also provide helpful suggestions for future research.

When and where did the ancestors of modern birds evolve? What enabled them to survive the meteoric impact that wiped out the dinosaurs? How did these early birds spread across the globe and give rise to the 10,600-plus species we recognise today from the largest ratites to the smallest hummingbirds? Based on the latest scientific discoveries and enriched by personal observations, The Ascent of Birds sets out to answer these fundamental questions. The Ascent of Birds is divided into self-contained chapters, or stories, that collectively encompass the evolution of modern birds from their origins in Gondwana, over 100 million years ago, to the present day. The stories are arranged in chronological order, from tinamous to tanagers, and describe the many dispersal and speciation events that underpin the world's 10,600-plus species. Although each chapter is spearheaded by a named bird and focuses on a specific evolutionary mechanism, the narrative will often explore the relevance of such events and processes to evolution in general. The book starts with The Tinamou's Story, which explains the presence of flightless birds in South America, Africa, and Australasia, and dispels the cherished role of continental drift as an explanation for their biogeography. It also introduces the concept of neoteny, an evolutionary trick that enabled dinosaurs to become birds and humans to conquer the planet. The Vegavis's Story explores the evidence for a Cretaceous origin of modern birds and why they were able to survive the asteroid collision that saw the demise not only of dinosaurs but of up to three-quarters of all species. The Duck's Story switches to sex: why have so few species retained the ancestral copulatory organ? Or, put another way, why do most birds exhibit the paradoxical phenomenon of penis loss, despite all species requiring internal fertilisation? The Hoatzin's Story reveals unexpected oceanic rafting from Africa to South America: a stranger-than-fiction means of dispersal that is now thought to account for the presence of other South American vertebrates, including geckos and monkeys. The latest theories underpinning speciation are also explored. The Manakin's Story, for example, reveals how South America's extraordinarily rich avifauna has been shaped by past geological, oceanographic and climatic changes, while The Storm-Petrel's Story examines how species can evolve from an ancestral population despite inhabiting the same geographical area. The thorny issue of what constitutes a species is discussed in The Albatross's Story, while The Penguin's Story explores the effects of environment on phenotype in the case of the Emperor penguin, the harshest on the planet. Recent genomic advances have given scientists novel approaches to explore the distant past and have revealed many unexpected journeys, including the unique overland dispersal of an early suboscine from Asia to South America (The Sapayoa's Story) and the blackbird's ancestral sweepstake dispersals across the Atlantic (The Thrush's Story). Additional vignettes update more familiar concepts that encourage speciation: sexual selection (The Bird-of-Paradise's Story); extended phenotypes (The Bowerbird's Story); hybridisation (The Sparrow's Story); and 'great speciators' (The White-eye's Story). Finally, the book explores the raft of recent publications that help explain the evolution of cognitive skills (The Crow's Story); plumage colouration (The Starling's Story); and birdsong (The Finch's Story)

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.

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

Previous experimental research has suggested that chimpanzees may understand some of the epitemological aspects of visual perception, such as how the perceptual act of seeing can have internal mental consequences for an individual's state of knowledge. Other research suggests that chimpanzees and other nonhuman primates may understand visual perception at a simpler level; that is, they may at least understand seeing as a mental event that subjectively anchors organisms to the external world. However, these results are ambiguous and are open to several interpretations. In this Monograph, we report the results of 15 studies that were conducted with chimpanzees and preschool children to explore their knowledge about visual perception.

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.

The relationship between brain and mind is one of the most baffling problems in science but potentially one of the most interesting. First published in 1985, this collection of original essays traces the development of mind in animals and human beings from its origins in the evolution of larger brains with a capacity for creating mental models of the environment. Examples are given of the way in which the brain may use this increased capacity to represent both the physical and social worlds, and the authors suggest that this type of mental activity might underly what human beings recognize in themselves as 'awareness' or 'consciousness'. Brain and Mind brings together much of the latest research and provides a useful framework for the study of this increasingly important subject. The contributors are experts in a wide range of disciplines and draw their conclusions from a broad base of clinical and experimental evidence. Students of psychology, zoology, anatomy, medicine and philosophy, as well as anyone who has wondered about their own mind and its relation to the brain, will find this a fascinating and stimulating source.

This book brings together for the first time, a collection of classic texts combined with a number of contemporary syntheses on the widely studied topic of behavioral development in animals.

Behavioral development is a major subject area in both animal behavior and experimental psychology since throughout the history of psychology and ethology, the study of development has played a crucial role and has been the subject of some of the major intellectual debates, for example the "Nature versus Nurture" issue. More recently, biological approaches to development, derived from work on animals, have become increasingly important and influential. "The Development of Animal Behaviour: A Reader" provides the key readings in these important areas of research in one volume. This "Reader" will therefore prove an invaluable resource for students and scholars who wish to engage with the study of animal behavioral development.

Primatology draws on theory and methods from diverse fields, including anatomy, anthropology, biology, ecology, medicine, psychology, veterinary sciences and zoology. The more than 500 species of primate range from tiny mouse lemurs to huge gorillas, and primatologists collect data in a variety of environments including in the field, research facilities, museums, sanctuaries, zoos, and from the literature. The variability in research interests, study animals and research sites means that there are no standard protocols for how to study primates. Nevertheless, asking good questions and designing appropriate studies to answer them are vital to produce high quality science. This accessible guide for graduate students and post-doctoral researchers explains how to develop a research question, formulate testable hypotheses and predictions, design and conduct a project and report the results. The focus is on research integrity and ethics throughout, and the book provides practical advice on overcoming common difficulties researchers face.

Provides the first general sourcebook for identification and treatment of most behavior problems encountered in livestock and pets. Hundreds of described behaviors are arranged alphabetically, cross-referenced, and cited to sources for additional information.

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.

Since the publication of The Migrations of Fish by Prof. Alexander Meek in 1916, a number of books have been published on this subject. However, most of these books only cover one type of migratory mechanisms. This book aims to overcome this drawback by presenting a comprehensive coverage of all life history strategies-potadromy, anadromy, catadromy, amphidromy and oceanodromy in one book. The first section of this book reviews the history of fish migration studies, the main definitions and concepts related with fish migration and the main trends and challenges of fish migration research. The second section describes the main processes and patterns associated with all migratory life history strategies, as well as the main problems associated with their conservation. Finally, the third section provides examples of the main methodologies used to study fish migration. This book was conceived with the objective to provide undergraduate and graduate students and researchers with a comprehensive book on which they could rely.

This book compares the beginning of symbolic thought in human infancy with that of our close primate relatives, the chimpanzees. The author investigates the precursors of symbolism by studying the actions and interactions of a small group of these intelligent, non-human primates who live in Singapore Zoo. Drawing upon his years of detailed observations, Matthews offers an in-depth analysis and interpretation of chimp behaviour to present an unprecedented account of the beginnings of symbolic thought. The book shows that the actions the chimpanzees perform have structural and semantic similarities with the actions of emergent expression and representation we find in human infancy. Of great importance is the finding that chimpanzee mark-making activity is not an artefact of human interference, but part of chimpanzee culture. Young chimpanzees seem to be introduced to acts of pretence and imagination by older and more experienced ones and taught the rudiments of expression, representation and symbolism. The implications for our understanding of symbolism, language, art and education are enormous, as are those about our origins and our place within nature. The book is written in an accessible style for both specialist and non-specialist readers, and illustrated with the author's drawings and photographs.

Beach-spawning fishes from exotic locations on most continents of the world provide spectacular examples of extreme adaptations during the most vulnerable life cycle stages. The beauty, intriguing biology, and importance of these charismatic fishes at the interface of marine and terrestrial ecosystems have inspired numerous scientific studies. Adaptations of behavior, physiology, development, and ecology are gathered together for the first time in this book. Beach-Spawning Fishes: Reproduction in an Endangered Ecosystem is a comprehensive guide to beach spawning, a charismatic animal behavior that is seen in a surprising number of teleost species. This unexpected form of reproduction provides a window into the ecology of coastal areas, the behaviors and physiology necessary for fishes and their eggs to adapt to terrestrial conditions, and the threats and challenges for conservation and management. Beach-spawning species include important forage fishes such as the capelin, exotic fishes such as the fugu puffer, and the spectacular midnight runs of the California grunion.

Bird migration is a well-researched phenological event. However, few studies in North America have investigated the effects of climate change and extreme weather on the relationships of migratory avian species and their seasonal resources. This is a critical gap in knowledge that limits our ability to prioritize management and conservation applications throughout the annual cycle. Phenological Synchrony and Bird Migration: Changing Climate and Seasonal Resources in North America explores critical linkages between migratory birds, their seasonal resources, and shifts in climate change and weather events. Gathered from projects conducted during spring or fall migration, the book covers topics such as: Conservation and management considerations for migratory birds throughout the United States with respect to climate change The relation of climate on the wintering grounds to spring migration of short- and long-distance migratory birds The relationships of migratory birds and their seasonal resources, and the nature of these relationships in the face of climate change and extreme weather events at stopover habitats in both spring and fall migration With contributions from over 40 researchers, the book will help readers understand the effects of climate change on migratory birds and will provide a solid basis for further inquiry and research in this area.
