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.

This book explores human decision-making heuristics and studies how nudging and winking can help citizens to make rational choices. By applying the behavioral economics approach to political outcomes, it demonstrates how economics can be employed for the greater societal good. It starts with a review of the current literature on human decision-making failures in Europe and North America, presenting the wide range of nudges and winks developed to curb the harmful consequences of human decision-making fallibility. It then discusses the use of mental heuristics, biases and nudges in the finance domain to benefit economic markets by providing clear communication strategies. Lastly, the author proposes clear leadership and followership directives on nudging in the digital age. This book appeals to scholars and policy makers interested in rational decision-making and the use of nudging and winking in the digital age.

This volume provides an empirical and conceptual overview of advances in our understanding of impulsivity and impulsive behaviors. Prominent scientists review the range of behavioral phenomena referred to as 'impulsive', as well as the defining features and psychological, neurocognitive and behavioral processes that underlie of the manifestation of impulsive behaviors, focussing on progress made and the questions remaining to be answered.

This book presents the facet theoretical framework as a tool for facilitating the conception of complex animal behaviour research and the design of research procedures through employing mapping sentences. Using the facet theoretical framework, this book takes a holistic view of bird behaviour. Components of bird behavior are identified and then reassembled to facilitate an understanding of the behaviour in the context of its natural occurrence. This provides new insight on both the parts of the behaviour and how these interact as a whole. The multi-faceted approach to designing, evaluating and understanding bird behavior presented offers a template that is adaptable for investigating a wide variety of avian species and different forms of behaviour. Behavioural biologists, animal and comparative psychologists, other natural and behavioural scientists, as well as students of these disciplines will find this book to be an interesting and enlightening read.

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 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.

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.

This book develops Gregory Bateson's ideas regarding "communication about relationship" in animals and human beings, and even nations. It bases itself on Bateson's theory of relational communication, as he described it in the zoosemiotics of octopus, mammals, birds, and human beings. This theory includes, for example, the roles of metaphor, play, analog and digital communication, metacommunication, and Laws of Form. It is organized around a letter from Gregory Bateson to his fellow cybernetic thinker Warren McCulloch at the time of the Cuban Missile Crisis. In this letter Bateson argued that what we would today call zoosemiotics, including Bateson's own (previously unpublished) octopus research, should be made a basis for understanding the relationship between the two blocs of the Cold War. Accordingly the book shows how Bateson understood interactive processes in the biosemiotics of conflict and peacemaking, which are analyzed using examples from recent animal studies, from primate studies, and from cultural anthropology. The Missile Crisis itself is described in terms of Bateson's critique of game theory which he felt should be modified by an understanding of the zoosemiotics of relational communication. The book also includes a previously unpublished piece by Gregory Bateson on wolf behavior and metaphor/ abduction.

Few things come more naturally to us than sex-or so it would seem. Yet to a chimpanzee, the sexual practices and customs we take for granted would appear odd indeed. He or she might wonder why we bother with inconveniences like clothes, why we prefer to make love on a bed, and why we fuss so needlessly over privacy. Evolution and Human Sexual Behavior invites us into the thought-experiment of imagining human sex from the vantage point of our primate cousins, in order to underscore the role of evolution in shaping all that happens, biologically and behaviorally, when romantic passions are aroused. Peter Gray and Justin Garcia provide an interdisciplinary synthesis that draws on the latest discoveries in evolutionary theory, genetics, neuroscience, comparative primate research, and cross-cultural sexuality studies. They are our guides through an exploration of the patterns and variations that exist in human sexuality, in chapters covering topics ranging from the evolution of sex differences and reproductive physiology to the origins of sexual play, monogamous unions, and the facts and fictions surrounding orgasm. Intended for generally curious readers of all stripes, this up-to-date, one-volume survey of the evolutionary science of human sexual behavior explains why sexuality has remained a core fascination of human beings throughout time and across cultures.

All science proceeds by progressively building on the work of others while remaining open to new discoveries and challenging existing conceptual frameworks. The same is true of culturo-behavior science. This textbook presents the scientifically rigorous work of the last several decades that has taken a behavior-analytic view of social and cultural processes, with an eye for contributions that address social and cultural issues. The chapters herein explore and elaborate on the history, theories, and methodologies of culturo-behavior science and those of its researchers and practitioners. Throughout this volume, the authors intentionally prompt students to both learn from and question the current theory and methods while shaping their own research and practice. This book presents multiple intersecting perspectives intended for graduate-level students of behavior analysis. Contributors to this volume include many of the major scholars and practitioners conducting research and/or practicing in communities and larger cultural systems. Their work is scientifically guided, systemic, and ecologically valid; it includes basic research as well as efforts having applications in community health, sustainability, environmental issues, and social justice, among other matters. There is material here to support specialists preparing to do research or practice within community and cultural-level systems. As well, students who intend to do direct and clinical work will find the background they need to make contributions to the field as engaged, informed citizens.

The Theraphosidae are the most famous and diverse mygalomorph spiders, and include some of the largest arachnids on earth. Their unique defense mechanisms, predatory tactics, reproductive strategies and ecological adaptations are displayed by a wide range of terrestrial, burrowing and arboreal species. These arachnids are familiar to the general public thanks to horror movies and a growing interest in tarantulas as pets; however, scientific information on the group is scattered throughout the literature and not easily available. This book reviews all major aspects of New World Theraphosid tarantulas and provides in-depth information on their evolution, taxonomy, behavior, physiology, ecology, reproduction, conservation and biogeography. As a comprehensive guide to the biology of tarantulas, it will appeal to researchers, students and terrarium hobbyists alike.

Despite its almost universal acclaim, the authors contend that evolutionary explanations must take into account the well-established fact that in mammals and birds, the transfer of learned information is both ubiquitous and indispensable. Animal Traditions maintains the assumption that selection of genes supplies both a sufficient explanation of evolution and a true description of its course. The introduction of the behavioral inheritance system into the Darwinian explanatory scheme enables the authors to offer new interpretations for common behaviors such as maternal behaviors, behavioral 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. This book will make stimulating reading for all those interested in evolutionary biology, sociobiology, behavioral ecology, and psychology.

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.

Motivation: A Biobehavioural Approach provides the reader with an understanding of why individuals exhibit certain behaviors, and what causes these actions. Roderick Wong presents an analysis of motivated behavior such as sexual activity, parental behavior, food selection, and fear or aggression, from a biological perspective. Each chapter focuses on the individual systems underlying specific motivational states that result in motivated acts. The author discusses similarities, differences, and integration between these motivational systems throughout the volume. Using a framework derived from research and theory from animal behavior and comparative psychology, he analyzes relevant issues in human motivation such as mate choice, nepotism, attachment and independence, sensation-seeking, obesity, and parent-offspring conflict. This book will be particularly useful for undergraduate students in psychology or behavioral science taking courses in motivation and emotion, comparative psychology, animal behavior, or biological psychology.

Mama's Last Hug is a fascinating exploration of the rich emotional lives of animals, beginning with Mama, a chimpanzee matriarch who formed a deep bond with biologist Jan van Hooff. Her story and others like it-from dogs "adopting" the injuries of their companions, to rats helping fellow rats in distress, to elephants revisiting the bones of their loved ones-show that humans are not the only species with the capacity for love, hate, fear, shame, guilt, joy, disgust, and empathy. Frans de Waal opens our hearts and minds to the many ways in which humans and other animals are connected.

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.

How does an understanding of the behavior of a given animal species contribute to its conservation? The answer has profound consequences for our efforts to conserve endangered species. Behaviour and Conservation links the extraordinary advances in behavioral ecology over the past thirty years with the new discipline of conservation biology. It shows how an evolutionary approach can help solve problems in practical conservation, and suggests a new direction for behavioral ecology. Leading authorities in animal behavior address the ways in which behavior and conservation interact, investigating the conservation impact of people, habitat loss and fragmentation, threats to wild populations of animals, conservation priorities, and the use of behavioral approaches for conservation applications.

Our closest living relatives, the chimpanzees, are familiar enough--bright and ornery and promiscuous. But they also kill and eat their kin, in this case the red colobus monkey, which may say something about primate--even hominid--evolution. This book, the first long-term field study of a predator-prey relationship involving two wild primates, documents a six-year investigation into how the risk of predation molds primate society. Taking us to Gombe National Park in Tanzania, a place made famous by Jane Goodall's studies, the book offers a close look at how predation by wild chimpanzees--observable in the park as nowhere else--has influenced the behavior, ecology, and demography of a population of red colobus monkeys.

As he explores the effects of chimpanzees' hunting, Craig Stanford also asks why these creatures prey on the red colobus. Because chimpanzees are often used as models of how early humans may have lived, Stanford's findings offer insight into the possible role of early hominids as predators, a little understood aspect of human evolution.

The first book-length study in a newly emerging genre of primate field study, "Chimpanzee and Red Colobus "expands our understanding of not just these two primate societies, but also the evolutionary ecology of predators and prey in general.

Information is a core concept in animal communication: individuals routinely produce, acquire, process and store information, which provides the basis for their social life. This book focuses on how animal acoustic signals code information and how this coding can be shaped by various environmental and social constraints. Taking birds and mammals, including humans, as models, the authors explore such topics as communication strategies for "public" and "private" signaling, static and dynamic signaling, the diversity of coded information and the way information is decoded by the receiver. The book appeals to a wide audience, ranging from bioacousticians, ethologists and ecologists to evolutionary biologists. Intended for students and researchers alike, it promotes the idea that Shannon and Weaver's Mathematical Theory of Communication still represents a strong framework for understanding all aspects of the communication process, including its dynamic dimensions.

Social learning commonly refers to the social transfer of information and skill among individuals. It encompasses a wide range of behaviors that include where and how to obtain food, how to interact with members of one's own social group, and how to identify and respond appropriately to predators. Mammalian Social Learning discusses a wide diversity of species, some of which have never been discussed in this context before, with particular reference made to their natural life strategies. Expert chapters consider social learning in humans in comparison with other mammals, especially in their technological and craft traditions. Moreover, for the first time, attention is given to the social learning abilities of prehistoric hominids.

This book sets out a framework for adaptive explanations of behavior, and uses it to provide analyses of a range of biological issues such as energetic gain, energy-predation trade-offs, dynamic games, state-dependent life histories, annual routines, and fluctuating environments. The volume gives a definitive account of this exciting new field, summarizing previous research, presenting new material, and suggesting directions for future research. The framework adopted in this book provides a common currency for comparing diverse actions. Ultimately this could lead to the development of state-dependent dynamic models. This book will be a revelation for graduate students and researchers interested in behavioral or evolutionary biology.

This book summarizes the latest research on the origins of language, with a focus on the process of evolution and differentiation of language. It provides an update on the earlier successful book, "The Origins of Language" edited by Nobuo Masataka and published in 2008, with new content on emerging topics. Drawing on the empirical evidence in each respective chapter, the editor presents a coherent account of how language evolved, how music differentiated from language, and how humans finally became neurodivergent as a species. Chapters on nonhuman primate communication reveal that the evolution of language required the neural rewiring of circuits that controlled vocalization. Language contributed not only to the differentiation of our conceptual ability but also to the differentiation of psychic functions of concepts, emotion, and behavior. It is noteworthy that a rudimentary form of syntax (regularity of call sequences) has emerged in nonhuman primates. The following chapters explain how music differentiated from language, whereas the pre-linguistic system, or the "prosodic protolanguage," in nonhuman primates provided a precursor for both language and music. Readers will gain a new understanding of music as a rudimentary form of language that has been discarded in the course of evolution and its role in restoring the primordial synthesis in the human psyche. The discussion leads to an inspiring insight into autism and neurodiversity in humans. This thought-provoking and carefully presented book will appeal to a wide range of readers in linguistics, psychology, phonology, biology, anthropology and music.

Behaviour describes animal and human behaviour, including environmental influence, behavioural development, courtship and social interaction. It covers all the material required for the study of behaviour at A-level, whilst at the same time providing an accessible and informative introduction to the fascinating science of behaviour. The authors provide a list of further reading for those who wish to learn more. The Advanced Biology Topics series of books will be of interest to students studying a wide variety of biological subjects at A-level, or as part of a vocational or undergraduate course.

This book describes the sampling and statistical methods used most often by behavioral ecologists and field biologists. Written by a biologist and two statisticians, it provides a rigorous discussion together with worked examples of statistical concepts and methods that are generally not covered in introductory courses, and which are consequently poorly understood and applied by field biologists. The first section reviews important issues such as defining the statistical population and the sampling plan when using nonrandom methods for sample selection, bias, interpretation of statistical tests, confidence intervals, and multiple comparisons. After a detailed discussion of sampling methods and multiple regression, subsequent chapters discuss specialized problems such as pseudoreplication, and their solutions. This volume will quickly become the favorite statistical handbook for all field biologists.

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.
