Mammalian Dispersal Patterns examines the ways that social structure affects population genetics and, in turn, rates of evolution, in mammalian groups. It brings together fieldwork in animal behavior and wildlife biology with theoretical work in demography and population genetics. The focus here is dispersal--whether, how, and when individuals leave the areas where they are born.
Theoretical work in population genetics indicates that such social factors as skewed sex ratios, restrictive mating patterns, and delayed age of first reproduction will lower the reproductive variability of a population by reducing the number of genotypes passed from one generation to the next. Field studies have shown that many mammalian species do exhibit many such social characteristics. Among horses, elephant seals, and a number of primates, the majority of females are inseminated by only a fraction of the males. In pacts of wolves and mongooses, usually only the highest-ranking male and female breed in a given season. Although socially restricted mating tends to lower genetic variability in isolated populations, it actually tends to increase genetic variability in subdivided populations with low rates of migration between subunits. Among some species there is little dispersal and thus little gene flow between subpopulations; other species travel far afield before mating.
The contributors to this volume examine actual data from populations of mammals, the way patterns of dispersal correlate with the genetic structure of individuals and populations, and mathematical models of population structure. This interdisciplinary approach has an important bearing on work in conservation of both wildlife and zoo populations, for it shows that the home range and the population size needed to maintain genetic variability can differ greatly from one species to the next. The volume also offers a fruitful model for future research.

Anthrozoology, the study of human-animal interactions (HAIs), has experienced substantial growth during the past 20 years and it is now timely to synthesise what we know from empirical evidence about our relationships with both domesticated and wild animals. Two principal points of focus have become apparent in much of this research. One is the realisation that the strength of these attachments not only has emotional benefits for people, but confers health benefits as well, such that a whole area has opened up of using companion animals for therapeutic purposes. The other is the recognition that the interactions we have with animals have consequences for their welfare too, and thus impact on their quality of life. Consequently we now study HAIs in all scenarios in which animals come into contact with humans, whether as pets/companions, farm livestock, laboratory animals, animals in zoos, or in the wild. This topical area of study is of growing importance for animals in animal management, animal handling, animal welfare and applied ethology courses, and also for people within psychology, anthropology and human geography at both the undergraduate and postgraduate level. It will therefore be of interest to students, researchers, and animal managers across the whole spectrum of human-animal contact.

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.

Despite their diversity, amphibians and reptiles share many physiological traits, such as their dependence on external heat sources for body temperature regulation, that are of pivotal importance to their ability to cope with the environment. Considerable variation in physiological capabilities exists in these groups and often can be related to seasonal and geographic differences in environmental parameters. This book provides a comprehensive and integrative view of the interplay between physiology and behavior in amphibians and reptiles, leading to a better understanding of the subject. The book covers topics that have recently been in the spotlight for scientific research on the physiology, behavior, and conservation of amphibians and reptiles. It brings together recent information from a range of disciplines that address critical topics for understanding their biology. As these studies are scattered across articles in specialized journals, this book provides a single and expanded source summarizing such advancements. Amphibian and Reptile Adaptations to the Environment: Interplay Between Physiology and Behavior maintains a solid scientific basis for the biological topics covered. However, it presents the material in a clear and direct manner so that it is accessible even to non-biologists interested in the basic biology, behavior, and ecology of these animals as well as how these elements are connected to their conservation.

Discover why animals do what they do, based on their genes, physiologies, cultures, traditions, survival and mating advantages, and evolutionary histories-and find out how studying behavior in the animal world helps us understand human behavior. The three volumes of Animal Behavior: How and Why Animals Do the Things They Do cover the breadth of the field, addressing causation, development, function, and evolution in a wide range of animals, from invertebrates to humans. Inspired by Nobel laureate Nikolaas Tinbergen's work, the first two volumes follow Tinbergen's four classic questions of animal behavior, while the third volume supplies integrated examples of Tinbergen's investigative process applied in specific cases. Written in an engaging, accessible manner ideal for college students as well as general audiences, this evidence-based collection provides a fascinating tour of animal behaviorists' findings, such as how animal communication can be truthful or deceitful, the deadly serious business behind clashes in the "battle of the sexes," and how documentation of animal behavior can lead to a deeper understanding of human behavior. Each chapter provides both historical background and information about current developments in animal behavior knowledge. Provides readers with personal narratives from the researchers themselves, enabling rare insights into how researchers think and what drives their studies Explains animal behavior on the animal's terms rather than anthropomorphizing its actions as is often done in the popular press and the media Includes a comprehensive glossary of behavioral terms

Infanticide is an extremely complex behavioral pattern that occurs throughout the animal kingdom and it must be considered not only in isolation but also from the viewpoint of an animal's care of its young. The concept of infanticide is considered in different mammals such as humans, primates, pinnipeds, lions, dwarf mongooses and prairie dogs and in non-mammals including insects and birds. This book also views the topic in different environmental conditions such as the natural habitat of an animal and animals kept in laboratory conditions.

Understanding the biology of the innumerable number of aquatic species on our planet is the focus of sustained research efforts. Environmental degradation, management or rehabilitation of wild stocks, and the forecasted climatic changes are fueling interest in the study of the ecology, feeding behavior, and nutrition of aquatic animals in their natural habitat. In parallel, the rapid expansion of aquaculture in many parts of the world has supported vigorous research programs on nutrition, and feeding of cultivated aquatic organisms. More than 250 aquatic species are cultivated on a commercial scale using a wide variety of production systems. This great diversity results in great opportunities and tremendous challenges. Topics covered in this book are as diverse as, feeding ecology of fish in their natural habitat, feeding behavior, digestive anatomy, biochemistry and physiology of different fish species at different life stages, the impact of diet on gastro-intestinal development and health, nutrition and disease resistance, and modeling conversion of food or feed inputs into biomass.

Pleasurable Kingdom marshalls the latest evidence that animals, like humans, enjoy themselves. It debunks the popular perception that life for most is a continuous, grim struggle for survival. Instead it suggests that creatures from birds to bats to baboons may feel good thanks to play, sex, touch, food, anticipation, comfort, aesthetics and more. Combining rigorous evidence, elegant argument and amusing anecdote, leading animal behaviour researcher Dr Jonathan Balcombe proposes that evolution favours sensory rewards because they drive living things to stay alive and reproduce. Animal pain and stress, once controversial, are now acknowledged by legislation in many countries. Likewise the possibility of positive feelings in creatures other than humans has important ramifications for science and society and is thus ripe for informed debate, Balcombe concludes.

"Rational Animals: The Teleological Roots of Intentionality" offers an original account of the intentionality of human mental states, such as beliefs and desires.
The account of intentionality in "Rational Animals" is broadly biological in its basis, emphasizing the continuity between human intentionality and the levels of intentionality that should be attributed to animal actions and states.
Establishing the goal-directed character of animal behavior, Mark Okrent argues that instrumentally rational action is a species of goal-directed behavior that is idiosyncratic to individual agents and is distinguished by its novelty and flexibility. He also argues that some nonlinguistic animals are capable of instrumental rationality and that in the first instance, the contents of beliefs and desires are individuated by the explanatory role of those states in rationally accounting for such instrumentally rational behavior.
The account of instrumental rationality offered in Rational Animals allows for understanding the practical rationality of linguistically competent human beings as a distinctive capacity of social animals capable of undertaking roles governed by socially sanctioned norms.
Rational Animals will be of interest to cognitive scientists, philosophers of mind, philosophers of biology, philosophers of action, ethologists, and those interested in the debates concerning animal intelligence.

Dr. Dolittle-and many students of animal communication-are wrong: animals cannot use language. This fascinating book explains why. Can animals be taught a human language and use it to communicate? Or is human language unique to human beings, just as many complex behaviors of other species are uniquely theirs? This engrossing book explores communication and cognition in animals and humans from a linguistic point of view and asserts that animals are not capable of acquiring or using human language. Stephen R. Anderson explains what is meant by communication, the difference between communication and language, and the essential characteristics of language. Next he examines a variety of animal communication systems, including bee dances, frog vocalizations, bird songs, and alarm calls and other vocal, gestural, and olfactory communication among primates. Anderson then compares these to human language, including signed languages used by the deaf. Arguing that attempts to teach human languages or their equivalents to the great apes have not succeeded in demonstrating linguistic abilities in nonhuman species, he concludes that animal communication systems-intriguing and varied though they may be-do not include all the essential properties of human language. Animals can communicate, but they can't talk.

This impressive collection features Richard Herrnstein's most important and original contributions to the social and behavioral sciences--his papers on choice behavior in animals and humans and on his discovery and elucidation of a general principle of choice called the matching law. In recent years, the most popular theory of choice behavior has been rational choice theory. Developed and elaborated by economists over the past hundred years, it claims that individuals make choices in such a way as to maximize their well-being or utility under whatever constraints they face; that is, people make the best of their situations. Rational choice theory holds undisputed sway in economics, and has become an important explanatory framework in political science, sociology, and psychology. Nevertheless, its empirical support is thin. The matching law is perhaps the most important competing explanatory account of choice behavior. It views choice not as a single event or an internal process of the organism but as a rate of observable events over time. It states that instead of maximizing utility, the organism allocates its behavior over various activities in exact proportion to the value derived from each activity. It differs subtly but significantly from rational choice theory in its predictions of how people exert self-control, for example, how they decide whether to forgo immediate pleasures for larger but delayed rewards. It provides, through the primrose path hypothesis, a powerful explanation of alcohol and narcotic addiction. It can also be used to explain biological phenomena, such as genetic selection and foraging behavior, as well as economic decision making.

This text presents the results of a research project carried out on foraging behaviour among African baboons and its consequences for survival and reproduction. Detailed data is provided on the feeding habits of each baboon, with an analysis of its nutrient intake. These figures are then compared with those in optimum diets. The most striking result of this study is that the baboon's subsequent survival and reproductive success could be accurately predicted from what they had eaten as yearlings. The animals with energy intakes closest to the optimum and protein intakes furthest above their requirements were most likely to survive to adulthood and to successfully produce offspring.

This volume presents an international group of researchers who model animal and human behavior--both simple and complex. The models presented focus on such subjects as the pattern of eating in meals and bouts, the energizing and shaping impact of reinforcers on behavior, transitive inferential reasoning, responding to a compound stimulus, avoidance and escape learning, recognition memory, category formation, generalization, the timing of adaptive responses, and chromosomes exchanging information. The chapters are united by a common interest in adaptive behavior--whether of human, animal, or artificial system--and clearly demonstrate the rich variety of ways in which this fascinating area of research can be approached.
In so doing, the book demonstrates the range of thought that qualifies as theorizing in the contemporary study of the mechanisms of adaptive behavior. It has two purposes: to bring together a very wide range of approaches in one place and to give authors space to explain how their ideas developed. Journal literature often presents fully-formed theories with no explanation of how an idea came to have the shape in which it is presented. In this volume, however, leaders in different fields provide background on the development of their ideas. Where once psychologists and a few zoologists had this field to themselves, now various types of computer scientists have added great energy to the mix.

Ever since Jane Goodall unlocked the mysteries of wild chimpanzees, and Dian Fossey lived among Mountain gorillas, the world has been captivated by primates and the people who study them. Here at last, is the riveting story of Birute Galdikas, a pioneering primatologist who has spent much of herlive studying orangutans.

In 1971, twenty-five-year-old Galdikas began living in the remote jungles of Indonesian Borneo, where she encountered menacing poachers, blood-sucking leeches and swarms of carnivorous insects. Determined to penetrate the world of the elusive "red ape" in the name of science and conservation, Galdikas embarked on a quest of more than twenty years to become the foremost chronicler of orangutan life. Her first task was to form a bond of trust with the animals, but her initial forays into their world were thwarted by skeptical and territorial orangutans like handsome Cara, who hurled dead branches at Galdikas from the tree canopy above. Eventually Galdikas became a surrogate member of the community, triumphantly claimed as "mother" by little Sugito, who clung to her fiercely, night and day, for months. Reflections of Eden is an exotic adventure, a history of vital scientific research, and the memoir of a remarkable woman.

Unsere Sinne - Sehen, Hoeren, Riechen, Schmecken und Tasten - bestimmen wesentlich unser Leben. Alles was wir wissen, wurde uns von unseren Sinnen vermittelt. Aber wie funktionieren unsere Sinne und wie kommt das Wissen uber die Welt in unseren Kopf? Nach welchen Kriterien entscheidet unser Gehirn, was zu tun ist? In diesem Sachbuch wird allgemeinverstandlich dargelegt, wie hoch entwickelt die Sinnesorgane bei Tieren und Menschen sind. Oft erreichen Sinnesleistungen die Grenze des physikalisch Moeglichen. Das Buch erklart, wie Sinnesreize erfasst werden, wie sie in die Sprache des Nervensystems ubersetzt werden und wie unser Gehirn Sinnesinformation verarbeitet. Das Gehirn setzt dabei auf wohl bewahrte Strategien, die ein Ziel verfolgen: die UEberlebenschance des Organismus zu erhoehen. Deshalb wird in diesem Buch gezeigt, wie sehr die Sinnesleistungen durch die Evolution geformt und bestimmt wurden. Das Buch zeigt auch, dass viele Tiere ihre Umwelt vollkommen anders wahrnehmen als wir. Fur die Neuauflage haben die Autoren den Text durchgesehen und auf den aktuellen Stand gebracht.

Although commonly believed that males are more promiscuous than females, new research has revealed that female infidelity is a common occurrence throughout the animal kingdom. Female Infidelity and Paternal Uncertainty is the first book to address how males deal with the consequences of female infidelity and the strategies they have evolved to try to avoid the possibility of raising an offspring they unknowingly did not sire. Each chapter deals with a specific evolved strategy developed to aid males in either limiting opportunities for their mate to be unfaithful or to "correct" the by-products of infidelity should it occur. With sections including mate guarding, intra-vaginal tactics and paternity assessment, this book will appeal to researchers and graduate students in behavioral biology, evolutionary psychology, human sexuality, anthropology, sociology, reproductive health and medicine.

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.

This encyclopedia, representing one of the most multi-disciplinary areas of research, is a comprehensive examination of the key areas in animal cognition and behavior. It will serve as a complementary resource to the handbooks and journals that have emerged in the last decade on this topic, and will be a useful resource for student and researcher alike. With comprehensive coverage of this field, key concepts will be explored. These include social cognition, prey and predator detection, habitat selection, mating and parenting, development, genetics, physiology, memory, learning and perception. Attention is also given to animal-human co-evolution and interaction, and animal welfare. All entries are under the purview of acknowledged experts in the field.

It has been shown through a variety of independent studies that members of the family Hyaenidae are consummate collectors of bones at their respective dens. This in turn has been inferred upon the fossil record suggesting hyaenids as the source for a number of fossil bearing cave deposits, especially in southern Africa. The question of how to differentiate between collections made by hyaenids, hominids and other bone collecting species has also been a highly published field of study. Here we take an in depth look at the bone collecting behaviours of the three extant bone collecting members of the family Hyaenidae, Crocuta crocuta, Parahyaena brunnea and Hyaena hyaena. Paying particular attention to distinctive carnivore gnawing and fragmentation patterns left upon the bones collected, we find that not only are there differences between the species of hyaenids but also within the species. It would appear that the environmental conditions at the time of collection have a greater than anticipated impact upon the taphonomic signatures left behind by the various hyaenid species. We conclude that for any study of fossil assemblages, one must take a multi-disciplined approach and examine not only the carnivore damage, but also palaeoenvironmental factors in determining the probable collector.

Essentials of the Cerebellum and Cerebellar Disorders is the first book of its kind written specifically for graduate students and clinicians. It is based on the 4-volume treatise, Handbook of the Cerebellum and Cerebellar Disorders (Springer, 2013), the definitive reference for scientists and neurologists in the field of cerebellar neurobiology. There have been fundamental advances in the basic science and clinical neurology of the cerebellum and its role in sensorimotor function and cognition. This monograph makes this large and expanding body of knowledge readily accessible to trainees and clinicians alike. The editors are world leaders in the field, and the chapters are authored by an international panel of experts drawn from ataxia clinics and cerebellar laboratories throughout North America, Europe and Asia. Essentials provides a solid grounding in the field of cerebellar research and ataxiology from cerebellar circuity to clinical practice, and it serves as a springboard to a deeper appreciation of both the principles and the complexities of cerebellar neurobiology. Clinicians are expected to have a deep appreciation of cerebellar disorders, not only in specialized ataxia clinics but also in adult and pediatric neurology, neurosurgery, psychiatry and neuropsychology practices, and in outpatient and inpatient rehabilitation settings. This book is an indispensable resource for students and practitioners navigating the evolving field of cerebellar motor and cognitive neurology. It also links to the more expansive Handbook for those who need to explore the topics in this monograph in greater depth.
