Animal behaviour, as a discipline, has undergone several key transitions over the last 25 years, growing in both depth and breadth. Key advances have been made in behavioural ecology and socio-biology, in the development of studies integrating proximate and ultimate causation, in the integration of laboratory and field work, and in advances in theoretical work in areas such as sexual selection, foraging and life-history traits. Thus it is appropriate to relate the individual stories of those who have had significant impacts on the field as we know it today. Leaders in Animal Behaviour: The Second Generation is a collection of autobiographies from 21 individuals that have been peer selected, and have provided unique and important contributions to the field in the past 25 years.

Bird song is one of the most remarkable and impressive sounds in the natural world, and has inspired not only students of natural history, but also great writers, poets and composers. Extensively updated from the first edition, the main thrust of the book is to suggest that the two main functions of song are attracting a mate and defending territory. It shows how this evolutionary pressure has led to the amazing variety and complexity we see in the songs of different species throughout the world. Writing primarily for students and researchers in animal behavior, the authors review over 1000 scientific papers and reveal how scientists are beginning to unravel and understand how and why birds communicate with the elaborate vocalizations we call song. Highly illustrated throughout and written in straightforward language, Bird Song also holds appeal for amateur ornithologists with some knowledge of biology.

Years back, Melissa Holbrook Pierson brought home a border collie named Mercy, without a clue of how to get her to behave. Stunned after hiring a trainer whose immediate rapport with Mercy seemed magical, Pierson began delving into the techniques of positive reinforcement. She made her way to B. F. Skinner, the behavioral psychologist who started it all, the man who could train a pigeon to dance in minutes and whose research on how behavior is acquired has ramifications for military dolphin trainers, athletes, dancers, and, as he originally conceived, society at large. To learn more, Pierson met with a host of fascinating animal behaviorists, going behind the scenes to witness the relationships between trainers and animals at the National Zoo in Washington, DC, and to the in-depth seminars at a Clicker Expo where all the dogs but hers seemed to be learning new tricks. The often startling story of what became of a pathbreaking scientist's work is interwoven with a more personal tale of how to understand the foreign species with whom we are privileged to live. Pierson draws surprising connections in her exploration of how kindness works to motivate all animals, including the human one.

Many mammals, such as otters, live in close association with rivers and streams, feeding in them, or using them as a place of safety or means of escape from predators. The distinct adaptations that riparian mammals have evolved in order to live in these environments also handicap them for living elsewhere. These animals are therefore threatened by alterations to their environment. In recent years, our rivers have become highly polluted, and have been subject to bankside modifications for agriculture and forestry, enhanced or decreased water flow, and recreation. As a result, they have become less and less suitable for these highly specialized animals. This book looks at the habitat utilization, adaptation, feeding ecology, and conservation status of a range of riparian mammals. It gives insights into the problems facing these fascinating animals, and how they might be overcome.

Social learning commonly refers to the social transfer of information and skill among individuals. It encompasses a wide range of behaviours that include where and how to obtain food, how to interact with members of one's own social group, and to identify and respond appropriately to predators. The behaviour of experienced individuals provides natural sources of information, by which inexperienced individuals may learn about the opportunities and hazards of their environment, and develop and modify their own behaviour as a result. A wide diversity of species is discussed in this book, some of which have never been discussed in this context before, and particular reference is made to their natural life strategies. Social learning in humans is also considered by comparison with other mammals, especially in their technological and craft traditions. Moreover, a discussion is included of the social learning abilities of prehistoric hominids.

As our closest primate relatives, chimpanzees offer tantalizing clues about the behavior of early human ancestors. This book provides a rich and detailed portrait of chimpanzee social life in the wild, synthesizing hundreds of thousands of hours of research at seven long-term field sites. Why are the social lives of males and females so different? Why do groups of males sometimes seek out and kill neighboring individuals? Do chimpanzees cooperate when they hunt monkeys? Is their vocal behaviour like human speech? Are there different chimpanzee 'cultures'? Addressing these questions and more, Adam Arcadi presents a fascinating introduction to the chimpanzee social universe and the challenges we face in trying to save this species from extinction. With extensive notes organized by field site and an appendix describing field methods, this book is indispensable for students, researchers, and anyone else interested in the remarkable and complex world of these intelligent apes.

Most large herbivores require some type of management within their habitats. Some populations of large herbivores are at the brink of extinction, some are under discussion for reintroduction, whilst others already occur in dense populations causing conflicts with other land use. Large herbivores are the major drivers for forming the shape and function of terrestrial ecosystems. This 2006 book addresses the scientifically based action plans to manage both the large herbivore populations and their habitats worldwide. It covers the processes by which large herbivores not only affect their environment (e.g. grazing) but are affected by it (e.g. nutrient cycling) and the management strategies required. Also discussed are new modeling techniques, which help assess integration processes in a landscape context, as well as assessing the consequences of new developments in the processes of conservation. This book will be essential reading for all involved in the management of both large herbivores and natural resources.

Behavioural observations from both the field and captivity indicate that same-sex sexual interactions are widespread throughout the animal kingdom, and occur quite frequently in certain non-human species. Proximate studies of these phenomena have yielded important insights into genetic, hormonal and neural correlates. In contrast, there has been a relative paucity of research on the evolutionary aspects. Homosexual Behaviour in Animals seeks to redress this imbalance by exploring animal same-sex sexual behaviour from an evolutionary perspective. Contributions focus on animals that routinely engage in homosexual behaviour and include birds, dolphin, deer, bison and cats, as well as monkeys and apes, such as macaques, gorillas and bonobos. A final chapter looks at human primates. This book will appeal to graduate students and researchers in evolutionary biology, biological anthropology, zoology, evolutionary psychology, animal behaviour and anyone interested in the current state of knowledge in this area of behavioural studies.

Since the development of game theory, the analysis of animal behaviour using the theories of economics has become a growing field of biological research in which models of games and markets play an important role. Studies of sexual selection, interspecific mutualism and intraspecific cooperation show that individuals exchange commodities to their mutual benefit; the exchange values of commodities are a source of conflict, and behavioural mechanisms such as partner choice and contest between competitors determines the composition of trading pairs or groups. These 'biological markets' can be examined to gain a better understanding of the underlying principles of evolutionary ecology. In this volume scientists from different disciplines combine insights from economics, evolutionary biology and the social sciences to look at comparative aspects of economic behaviour in humans and other animals. Aimed primarily at evolutionary biologists and anthropologists, it will also appeal to psychologists and economists interested in an evolutionary approach.

Animal Traditions maintains that the assumption that the selection of genes supplies both a sufficient explanation of the evolution and a true description of its course is, despite its almost universal acclaim, wrong. Eytan Avital and Eva Jablonka contend that evolutionary explanations must take into account the well-established fact that in mammals and birds, the transfer of learnt information is both ubiquitous and indispensable. The introduction of the behavioural inheritance system into the Darwinian explanatory scheme enables the authors to offer new interpretations for common behaviours such as maternal behaviours, behavioural conflicts within families, adoption and helping. This approach offers a richer view of heredity and evolution, integrates developmental and evolutionary processes, suggests new lines for research, and provides a constructive alternative to both the selfish gene and meme views of the world. It will make stimulating reading for all those interested in evolutionary biology, sociobiology, behavioural ecology and psychology.

Biology and Freedom is an essay on human nature; an attempt to make a just assessment of a species often presented as predominantly and unavoidably violent, greedy, and stupid. Likening human beings to animals is a traditional method of influencing attitudes on questions of morals and politics. Here, Professor Barnett shows that modern ethology, experimental psychology, genetics, and evolutionary theory give the currently fashionable misanthrophy no authentic support. He asks whether the theory of evolution has any bearing on, for instance, Machiavellianism in politics or the concept of original sin; and whether laboratory experiments on the effects of reward and punishment tell us anything useful about why we work, or about the enigma of free will. Combining the findings of modern biology with logic and humor, Professor Barnett gives a lucid alternative portrait of humanity. He stresses the questions that the complexities of human existence will raise long after the currently fashionable theories have faded. All those interested in these questions, in the truth about human nature, and in the future of human society will want to read this book.

A unified approach to the study of domestic animals is an important step in achieving a proper understanding of the nature of domestication. In this book, the author has successfully brought together data from many different fields. It emphasises the importance of domestic animals to the development of human civilization and demonstrates how human control of domestication may result in the planned production of distinct kinds of domestic animals, bred specifically to improve food production, build up alternative methods of land use or provide new laboratory animals for use in scientific research. The text concentrates on the importance of changes in animal behaviour to the process of domestication and describes how one of the characteristics of domesticated animals is a lack of the same kind of perception of their surrounding environment as is shown by wild animals. New results and ideas are presented and the book demonstrates how the practical application of a theoretical strategy for domestication resulted in the production of the first primitive, but truly domestic, fallow deer.

The purpose of migration, regardless of the distance involved, is to exploit two or more environments suitable for survival or reproduction over time, usually on a seasonal basis. Yet individual organisms can practice the phenomenon differently, and birds deploy unique patterns of movement over particular segments of time. Incorporating the latest research on bird migration, this concise, critical assessment offers contemporary readers a firm grasp of what defines an avian migrant, how the organism came to be, what is known about its behavior, and how we can resolve its enduring mysteries. John H. Rappole's sophisticated survey of field data clarifies key ecological, biological, physiological, navigational, and evolutionary concerns. He begins with the very first migrants, who traded a home environment of greater stability for one of greater seasonality, and uses the structure of the annual cycle to examine the difference between migratory birds and their resident counterparts. He ultimately connects these differences to evolutionary milestones that have shaped a migrant lifestyle through natural selection. Rather than catalogue and describe various aspects of bird migration, Rappole considers how the avian migrant fits within a larger ecological frame, enabling a richer understanding of the phenomenon and its critical role in sustaining a hospitable and productive environment. Rappole concludes with a focus on population biology and conservation across time periods, considering the link between bird migration and the spread of disease among birds and humans, and the effects of global warming on migrant breeding ranges, reaction norms, and macroecology.

Sexual Selection in Primates provides an up-to-date account of all aspects of sexual selection in primates, combining theoretical insights, comprehensive reviews of the primate literature and comparative perspectives from relevant work on other mammals, birds and humans. Topics include sex roles, sexual dimorphism in weapons, ornaments and armaments, sex ratios, sex differences in behaviour and development, mate choice, sexual conflict, sex-specific life history strategies, sperm competition and infanticide. The outcome of the evolutionary struggle between the sexes, the flexibility of roles and the leverage of females are discussed and emphasised throughout. Sexual Selection in Primates is aimed at graduates and researchers in primatology, animal behaviour, evolutionary biology and comparative psychology.

In this edited collection, 17 internationally known authorities bring together the results of recent research on the natural history, ecology, behavior, morphology, and genetics of wasps as they pertain to the evolution of social behavior. The first part of the book opens with a review of the classification of the family Vespidae along with a revision of the subfamily Polistinae. Seven subsequent chapters deal with the natural history and social biology of each of the major taxa of social and presocial vespids. The second part of the book offers chapters on reproductive competition; worker polyethism; evolution of nest architecture, of queen number and queen control, and of exocrine glands; population genetics; the nutritional bsis of social evolution; and the nest as the locus of social life. The final chapter is a comparative discussion of social behavior in the Sphecidae, the only family of wasps besides the Vespidae in which well-developed social behavior is known. Providing a wealth of information about the biology of wasps, this comprehensive, up-to-date volume will be an essential reference for entomologists, evolutionary biologists, behavioral ecologists, ethologists, and zoologists.

Cooperative breeders are species in which more than a pair of individuals assist in the production of young. Cooperative breeding is found in only a few hundred bird species world-wide, and understanding this often strikingly altruistic behaviour has remained an important challenge in behavioural ecology for over 30 years. This book highlights the theoretical, empirical and technical advances that have taken place in the field of cooperative breeding research since the publication of the seminal work Cooperative Breeding in Birds: Long-term Studies of Behavior and Ecology (1990, HB ISBN 0521 372984, PB ISBN 0521 378907). Organized conceptually, special attention is given to ways in which cooperative breeders have proved fertile subjects for testing modern advances to classic evolutionary problems including those of sexual selection, sex-ratio manipulation, life-history evolution, partitioning of reproduction and incest avoidance. It will be of interest to both students and researchers interested in behaviour and ecology.

Unlike most other large mammals, the Soay sheep population of Hirta in the St. Kilda archipelago show persistent oscillations, sometimes increasing or declining by more than 60% in a year. This study explores the causes of these oscillations and their consequences for selection on genetic and phenotypic variation within the population, drawing on studies over the past twenty years of the life-histories and reproductive careers of many sheep. It will be essential reading for vertebrate ecologists, demographers, evolutionary biologists and behavioral ecologists.

The keeping of zoo animals is a central tool in the conservation of some of the world's most fascinating, yet threatened, species. But how do zoos operate on a day-to-day basis? What are the key challenges they face in trying to feed, manage, and keep healthy the animals in their care? How can they play their part in conserving biodiversity? Zoo Animals: Behaviour, Management and Welfare addresses the key questions surrounding the keeping of exotic animals in captivity, and reveals how we can apply our ever-growing understanding of animal behaviour and use an evidence based approach to ensure zoo animals are managed as effectively as possible. Drawing on their extensive experience of zoo research, practice, and teaching, the authors blend together theory with a broad range of both mammalian and non-mammalian examples to give a highly-readable overview of this burgeoning field. Zoo Animals: Behaviour, Management, and Welfare is the ideal resource for anyone needing a thorough grounding in this subject, whether as a student or as a zoo professional. Online Resource Centre The Online Resource Centre to accompany Zoo Animals features: For all readers: * Updates - surveys of key developments in the field * Multiple choice questions with instant feedback, to aid self-assessment For registered adopters of the book: * Figures from the book in electronic format and full colour, available for download

This multi-author volume provides both a conceptual context and an instruction in methods for many aspects of sex ratio research. The book discusses theory, statistical analysis, and genetics, as well as research in one of a wide spectrum of animal, plant, and microbial taxa. Sex Ratios: Concepts and Research Methods is primarily intended for graduate and professional behavioral and evolutionary ecologists in this field, but it will also be useful to biologists building evolutionary models, and researchers analyzing data involving proportions or comparisons across phylogenetically related species.

Hans Kruuk, a life-long naturalist, tells the fascinating story of carnivores and humans' intricate relationships with them. The book is illustrated with specially commissioned drawings, and deals not only with the wild beauty of carnivores and their conservation, but also with the topics of furs and medicine, man-eaters and sheep-killers. Kruuk explains in simple terms the role of carnivores in nature, how they impact human life, art and literature, and how we instinctively respond to them and why.

This volume brings together primary data from a variety of primate species living in both natural habitats and experimental settings, and explores the variables that may play a role in primates' behavioral strategies. Taken together, these studies demonstrate that predator sensitive foraging is relevant to many primates, of various body sizes and group sizes and living in different environments. Eat or be Eaten encourages further discussion and investigation of the subject and will make fascinating reading for researchers and students in primatology, ecology, and animal behavior.

Die vorliegende Studie wurde im Juli 2000 von den Philosophischen Fakultaten I und II und von der Erziehungswissenschaftlichen Fakultat der Friedrich-Alexander-Universitat Erlangen-Nurnberg als Habilitationsschrift angenommen. Mein Dank gilt all jenen, die mich wahrend der Entstehung der Arbeit auf ganz unter- schiedliche Weise unterstutzt haben. Dies gilt zuallererst den Gutachtern der Arbeit, Herrn Prof. Dr. Roland Sturm, Herrn Prof. Dr. Jurgen Gebhardt und Herrn Prof. Dr. Wolfgang Rudzio. Daneben danke ich meinen Interviewpartnern, die sich trotz ihres knappen Zeitbudgets oft stundenlang meinen Fragen stellten, ebenso den Mitarbeitern in den Landtagsverwaltungen und Staatskanzleien, die mir den Zugang zu unverzichtbaren Materialien ermoeglichten. Ohne die Bereitschaft der Koalitionsakteure und der Vertreter der Oppositionsfraktionen in den untersuchten Landtagen, mir Einblicke in die informel- len Ablaufe des Koalitionsmanagements zu gewahren, waren die Fallstudien -und damit die Studie insgesamt -nicht durchfuhrbar gewesen. Halle, im Dezember 2000 Sabine Kropp Teill Zur Konzeptionalisierung des Regierungshandelns von Koalitionen 1. Gegenstand und Aufbau der Studie Koalitionen werden gern als Ehen auf Zeit, als Zweckehen, als Zwangsehen gar tituliert. Im besten Fall, dies deuten solche Umschreibungen an, gehen die Partner in solchen Gemeinschaften rucksichtsvoll miteinander um. Eine Liebesheirat jedoch sagt man Parteien nur in den seltensten Fallen nach; auch Scheidungen werden zuweilen in Kauf genommen. Den Vorteilen des gemeinsamen Zusammenlebens zuliebe, ordnen die Partner ihre Bedurfnisse und individuellen Interessen zwar bis zu einem gewissen Grad der politischen Lebensgemeinschaft unter. Lieber aber wurden sie alleine leben und Alltagsentscheidungen ohne Mitsprache ihres Partners treffen.

Infanticide by males is relatively common in primates, carnivores, and rodents, although it tends to be rare even in species in which it occurs. Is this behavior pathological or accidental, or does it reflect a conditional reproductive strategy for males in certain circumstances? In this book, case studies and reviews confirm the adaptive nature of infanticide by males in primates, and help to predict which species should be vulnerable to this phenomenon. Much of the book is devoted to exploring the evolutionary consequences of the threat of infanticide by males for social and reproductive behavior and physiology. Written for graduate students and researchers in animal behavior, behavioral ecology, biological anthropology, and social psychology, this book shows that social systems are shaped by ecological pressures, as well as social pressures such as infanticide risk.

The size and composition of primate groups varies tremendously across species, within species, and within groups over time. Written by leading authorities, this book focuses on the causes and consequences of variation in the number of males per group. This variation lies at the heart of understanding adaptive variation among primate social systems. The volume also provides an extensive overview of variation in group composition across all major primate taxa using up-to-date reviews, case studies, evolutionary theory, and theoretical models. A comparative review of birds and selected other mammals is included. This text will become a favorite with all those interested in the behavioral ecology of primates.
