The New World primates have radiated widely in tropical America, evolving a variety of adaptations to cope with different ways of life. This comparative survey examines many species. Some are highly specialized in unique ways; others have paralleled the lemurs of Madagascar or the monkeys and apes of Africa and Asia. The author's emphasis is on natural history, behavior, and ecology. Topics include geographical distributions, habitat preferences, territorial arrangements, activity rhythms, feeding techniques, defense mechanisms, and competition and cooperation among individuals of the same species. Much of the material is new, based on recent research in the field. Social reactions and organizations, and communication systems, are discussed in order to consider their implications for the evolution of primates in general and the development of languages and intelligence.

Covering the behavior and ecology of the northern fur seal, this book is a model long-term study of marine mammals, one that tests theory through both observation of undisturbed behavior and manipulative experiments on individuals. Here Roger Gentry draws on nearly two decades of research on three different islands to show how behavior among these seals changes with population size, sex ratio, and environment, to explain the behavior of the population beginning with individuals, and to generalize the results to other members of the eared seal family. In so doing, he offers one of the most comprehensive studies of its kind on any marine mammal species to date.

Gentry shows that the species is driven by very different behavioral traits than have been assumed for it in the past. His book analyzes behavior on scales of hours to lifetimes, investigates the mating system, considers processes that underlie the mating system (site fidelity, behavioral estrus, and the development of territoriality), and addresses specific aspects of maternal strategy (female attendance behavior, pup growth, seasonal influences, and the effects of continental shelf width). Gentry contributes to knowledge about marine mammals by providing a very specific basis for interspecies comparisons, and he suggests a link between population trend and environmental regime shifts. He also guides the debate over seal mating systems from an interpretive to an empirical or experimental basis.

Robin Dunbar uses economic models to explore the social behavior of the gelada baboon (Theropithecus gelada), a unique species, whose social system is one of the most complex among the primates. His work illustrates the value of an approach that views social behavior as being ultimately concerned with reproduction and with the maximizing of an individual's contribution to its species' gene pool.

What is animal welfare? Why has it proved so difficult to find a definition that everyone can agree on? This concise and accessible guide is for anyone who is interested in animals and who has wondered how we can assess their welfare scientifically. It defines animal welfare as 'health and animals having what they want', a definition that can be easily understood by scientists and non-scientists alike, expresses in simple words what underlies many existing definitions, and shows what evidence we need to collect to improve animal welfare in practice. Above all, it puts the animal's own point of view at the heart of an assessment of its welfare. But, can we really understand what animals want? A consistent theme running through the book is that not only is it possible to establish what animals want, but that this information is vital in helping us to make sense of the long and often confusing list of welfare measures that are now in use such as 'stress' and 'feel good hormones', expressive sounds and gestures, natural behaviour, cognitive bias, and stereotypies. Defining welfare as 'health and what animals want' allows us to distinguish between measures that are simply what an animal does when it is alert, aroused, or active and those measures that genuinely allow us to distinguish between situations the animals themselves see as positive or negative. Sentience (conscious feelings of pleasure, pain, and suffering) is for many people the essence of what is meant by welfare, but studying consciousness is notoriously difficult, particularly in non-human species. These difficulties are discussed in the context of our current - and as yet incomplete - knowledge of human and animal consciousness. Finally, the book highlights some key ideas in the relationship between animal welfare science and animal ethics and shows how closely the well-being of humans is linked to that of other animals. The Science of Animal Welfare is an ideal companion for undergraduate and graduate students taking courses in animal behaviour and welfare, as well as for professional researchers, practitioners and animal welfare consultants. At the same time, it is easily understandable to non-scientists and anyone without prior knowledge but with an interest in animals and the rapidly evolving science of animal welfare.

This booklet is part of a series of booklets on deer in Britain and gives details about the biology and ecology of Sika deer in Great Britain.

The badgers of Wytham Woods (Oxford, UK) have been studied continuously and intensively by David Macdonald for almost 50 years (25 of them with his former student and co-author Chris Newman), generating a wealth of data pertaining to every facet of their ecology and evolution. Through a mix of accessible, highly readable prose and cutting-edge science, the authors weave a riveting scientific story of the lives of these intriguing creatures, highlighting the insights offered to science more broadly through badgers as a model system. They provide a paradigm - from population down to molecule - for a deeper understanding of mammalian behaviour, ecology, epidemiology, evolutionary biology, and conservation. The real value of this long-term study is particularly apparent with current and globally relevant challenges such as climate change, disease epidemics, and senescence. This unique dataset enables us to examine these issues in a context that only a half-century experiment can reveal. The Badgers of Wytham Woods will appeal to a broad audience of professional academics (especially carnivore and mammalian biologists), researchers and students at all levels, governmental and non-governmental wildlife bodies, and to the natural historian fascinated by wild animals and the remarkable processes of nature they exemplify.

From foraging patterns in a single tree to social interactions across a home range, how primates use space is a key question in the field of primate behavioral ecology. Drawing on the latest advances in spatial analysis tools, this book offers practical guidance on applying geographic information systems (GIS) to central questions in primatology. An initial methodological section discusses niche modelling, home range analysis and agent-based modelling, with a focus on remote data collection. Research-based chapters demonstrate how ecologists apply this technology to a suite of topics including: calculating the intensity of use of both range and travel routes, assessing the impacts of logging, mining and hunting, and informing conservation strategies.

Amy Vedder leads a wild life. How many people can say they were once a member of a mountain gorilla family? Amy Vedder is a wildlife biologist, a scientist who studies animals and their behavior. She uses her knowledge to save animals whose lives and habitats are threatened. She once lived in a remote part of central Africa, where she helped rescue Rwanda's mountain gorillas from extinction. Amy did groundbreaking science in a beautiful rain forest environment, but it wasn't always easy. She had to face tough conditions in a country affected by conflict and war. In the process, she met unforgettable people and unforgettable gorillas. Today Amy travels the world, from her home base at New York's Bronx Zoo to the far reaches of Mongolia in Asia. Everywhere she goes, she teaches people how to appreciate and protect the precious wildlife that surrounds them. Gorilla Mountain is an exciting and inspiring story of true tale adventure. Young readers everywhere will be moved by the story of the young nature lover who became a powerful champion of great apes.

This is a re-examination of the story around the capture and disappearance of a mysterious creature in BC in 1884.

Beavers are represented by two extant species, the Eurasian beaver (Castor fiber) and the North American beaver (Castor canadensis); each has played a significant role in human history and dominated wetland ecology in the northern hemisphere. Their behaviour and ecology both fascinate and perhaps even infuriate, but seemingly never fail to amaze. Both species have followed similar histories from relentless persecution to the verge of extinction (largely through hunting), followed by their subsequent recovery and active restoration which is viewed by many as a major conservation success story. Beavers have now been reintroduced throughout Europe and North America, demonstrating that their role as a keystone engineer is now widely recognised with proven abilities to increase the complexity and biodiversity of freshwater ecosystems. What animals other than humans can simultaneously act as engineers, forest workers, carpenters, masons, creators of habitats, and nature managers? Over the last 20 years, there has been a huge increase in the number of scientific papers published on these remarkable creatures, and an authoritative synthesis is now timely. This accessible text goes beyond their natural history to describe the impacts on humans, conflict mitigation, animal husbandry, management, and conservation. Beavers: Ecology, Behaviour, Conservation, and Management is an accessible reference for a broad audience of professional academics (especially carnivore and mammalian biologists), researchers and graduate students, governmental and non-governmental wildlife bodies, and amateur natural historians intrigued by these wild animals and the extraordinary processes of nature they exemplify.

From a modest beginning in the form of a little shrew-like, nocturnal, insect eating ancestor that lived 200 million years ago, mammals evolved into the huge variety of different kinds of animals we see today. Many species are still small, and follow the lifestyle of the ancestor, but others have adapted to become large grazers and browsers, like the antelopes, cattle, rhinos, and elephants, or the lions, hyaenas, and wolves that prey upon them. Yet others evolved to be specialist termite eaters able to dig into the hardest mounds, or tunnel creating burrowers, and a few took to the skies as gliders and the bats. Many live partly in the water, such as otters, beavers, and hippos, while whales and dugongs remain permanently in the seas, incapable of ever emerging onto land. In this Very Short Introduction T. S. Kemp explains how it is a tenfold increase in metabolic rate - endothermy or "warm-bloodedness" - that lies behind the high levels of activity, and the relatively huge brain associated with complex, adaptable behaviour that epitomizes mammals. He describes the remarkable fossil record, revealing how and when the mammals gained their characteristics, and the tortuous course of their subsequent evolution, during which many bizarre forms such as sabre-toothed cats, and 30-tonne, 6-m high browsers arose and disappeared. Describing the wonderful adaptations that mammals evolved to suit their varied modes of life, he also looks at those of the mainly arboreal primates that culminated ultimately in Homo sapiens. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Zoos, aquariums, and wildlife parks are vital centers of animal conservation and management. For nearly fifteen years, these institutions have relied on "Wild Mammals in Captivity" as the essential reference for their work. Now the book reemerges in a completely updated second edition. "Wild Mammals in Captivity" presents the most current thinking and practice in the care and management of wild mammals in zoos and other institutions. In one comprehensive volume, the editors have gathered the most current information from studies of animal behavior; advances in captive breeding; research in physiology, genetics, and nutrition; and new thinking in animal management and welfare. In this edition, more than three-quarters of the text is new, and information from more than seventy-five contributors is thoroughly updated. The standard text for all courses in zoo biology, "Wild Mammals in Captivity" will, in its new incarnation, continue to be used by zoo managers, animal caretakers, researchers, and anyone with an interest in how to manage animals in captive conditions.

Embracing more than 5,000 genera, distributed in 425 families and 46 orders, Malcolm C. McKenna and Susan K. Bell's "Classification of Mammals" is the most comprehensive work to date on the systematics, relationships, and occurrences of all mammal taxa, living and extinct, down through the rank of genus.

Since George Gaylord Simpson's 1945 classification, the paleontological record has been recalibrated, and the intervening years have seen much debate and progress concerning the theoretical underpinnings of systematization. McKenna inherited the project from Simpson and, with Bell, has constructed a completely updated hierarchical system that reflects the genealogy of Mammalia.

In The Mountain Grizzly the author offers readers a glimpse into the seldom-seen life of the grizzly bear. Filled with more than 100 stunning pictures, Quinton has called upon twenty years of wildlife photography experience to create a spectacular photo essay. This diverse collection of images gives readers new insight into grizzly behaviour and an appreciation for this remarkable animal.

Despite many encouraging developments in the field of animal-free technologies, well-defined animal models are still needed to study fundamental properties of human diseases and to develop new prophylactic and therapeutic treatments against human diseases. Non-human primates (NHP) make up only a small, but important, part of the total number of animals used in biomedical and preclinical research. Due to their close phylogenetic relationship and the shared susceptibility to many human diseases, NHP can provide important research models to study these diseases and, as such, play a critical role in the advancement of various areas in the medical field. Studies in NHP have contributed to our understanding of various diseases and fundamental biological phenomena and they continue to be important in the development of new therapies, treatments, drugs and vaccines. Moreover, NHP models also contribute to our general knowledge of the processes that underlie non-disease and disease conditions. Important areas where NHP can provide important information include (emerging) infectious diseases, organ transplantation, neurological and aging-related disorders. Although not covered in this book due to time constraints, the need for, and benefits of, NHP models has been demonstrated most recently in the SARS-CoV-2 pandemic. The present book is the second of two volumes and covers important disease areas where NHP are used as model species. This volume includes different chapters on NHP models in infectious diseases, aging, neurodegenerative disorders, organ transplantation and cancer.

Primates communicate with each other using a wide range of signals: olfactory signals to mark territories, screams to recruit help while fighting, gestures to request food and facial expressions to initiate play. Primate Communication brings together research on all forms of interchange and discusses what we know about primate communication via vocal, gestural, facial, olfactory and integrated multimodal signals in relation to a number of central topics. It explores the morphological, neural and cognitive foundations of primate communication through discussion of cutting-edge research. By considering signals from multiple modalities and taking a unified multimodal approach, the authors offer a uniquely holistic overview of primate communication, discussing what we know, what we don't know and what we may currently misunderstand about communication across these different forms. It is essential reading for researchers interested in primate behaviour, communication and cognition, as well as students of primatology, psychology, anthropology and cognitive sciences.

In this masterwork, Russell H. Tuttle synthesizes a vast research literature in primate evolution and behavior to explain how apes and humans evolved in relation to one another, and why humans became a bipedal, tool-making, culture-inventing species distinct from other hominoids. Along the way, he refutes the influential theory that men are essentially killer apes--sophisticated but instinctively aggressive and destructive beings. Situating humans in a broad context, Tuttle musters convincing evidence from morphology and recent fossil discoveries to reveal what early primates ate, where they slept, how they learned to walk upright, how brain and hand anatomy evolved simultaneously, and what else happened evolutionarily to cause humans to diverge from their closest relatives. Despite our genomic similarities with bonobos, chimpanzees, and gorillas, humans are unique among primates in occupying a symbolic niche of values and beliefs based on symbolically mediated cognitive processes. Although apes exhibit behaviors that strongly suggest they can think, salient elements of human culture--speech, mating proscriptions, kinship structures, and moral codes--are symbolic systems that are not manifest in ape niches. This encyclopedic volume is both a milestone in primatological research and a critique of what is known and yet to be discovered about human and ape potential.

The dwarf and mouse lemurs of Madagascar are two very species-rich lemur genera, yet there is a relative paucity of information on this primate family in published literature. In this first ever treatment of the Cheirogaleidae, international experts are brought together to review and integrate our current knowledge of the behaviour, physiology, ecology, genetics and biogeography of these species. A wide range of direct and indirect research methods that are currently used to study these cryptic nocturnal solitary foragers are described. By uniting often disparate research on captive and free-ranging taxa and synthesising recent methodological advances, this book provides new insights that will encourage further studies of this fascinating primate family. This synthesis will provide an incentive for more integrative studies of the Cheirogaleidae in captivity and in the wild, enabling the impacts of deforestation and other factors to be identified and directions for future conservation efforts to be established.

The musteloids are the most diverse super-family among carnivores, ranging from little known, exotic, and highly-endangered species to the popular and familiar, and include a large number of introduced invasives. They feature terrestrial, fossorial, arboreal, and aquatic members, ranging from tenacious predators to frugivorous omnivores, span weights from a 100g weasel to 30kg giant otters, and express a range of social behaviours from the highly gregarious to the fiercely solitary. Musteloids are the subjects of extensive cutting-edge research from phylogenetics to the evolution of sociality and through to the practical implications of disease epidemiology, introduced species management, and climate change. Their diversity and extensive biogeography inform a wide spectrum of ecological theory and conservation practice. The editors of this book have used their combined 90 years of experience working on the behaviour and ecology of wild musteloids to draw together a unique network of the world's most successful and knowledgeable experts. The book begins with nine review chapters covering hot topics in musteloid biology including evolution, disease, social communication, and management. These are followed by twenty extensive case studies providing a range of comprehensive geographic and taxonomic coverage. The final chapter synthesises what has been discussed in the book, and reflects on the different and diverse conservation needs of musteloids and the wealth of conservation lessons they offer. Biology and Conservation of Musteloids provides a conceptual framework for future research and applied conservation management that is suitable for graduate level students as well as professional researchers in musteloid and carnivore ecology and conservation biology. It will also be of relevance and use to conservationists and wildlife managers.

The most commonly kept domestic animal in the developed world, the cat has been a part of human life for thousands of years. Cats have been both worshipped and persecuted over this long period - either loved or hated for their enigmatic self-reliance and the subject of numerous myths and fables. Highlighting startling discoveries made over the last ten years, this new edition features contributions from experts in a wide range of fields, providing authoritative accounts of the behaviour of cats and how they interact with people. Thoroughly revised and updated to include information on the basic features of cat development and social life, the history of their relations with humans, health and welfare problems, and the breeding of cats for sale and for show. It is intended for all those, whether specialist or general reader, who love or are simply intrigued by these fascinating animals.

The cheetah, the fastest terrestrial animal, has widespread appeal amongst wildlife biologists and enthusiasts alike. However, like all all large carnivores, it is increasingly threatened by habitat loss and its status is now classified as 'Vulnerable' by the IUCN. This is the first comprehensive study of cheetah biology in an arid environment, a major component of its current distribution range. The book brings together results from an intensive six year study of the cheetah by the authors in the Kgalagadi Transfrontier Park in South Africa and Botswana. It documents a wealth of detailed and direct observations of cheetah population biology and behavioural ecology, adopting an evolutionary approach and providing a conceptual framework for future research and applied management in the context of global environmental change. Kalahari Cheetahs covers topics such as optimal foraging theory, hunting strategies and predator prey relations, mating systems and reproductive strategies and success, inter-specific competition, demography, social organisation, and population limitation. Comparisons with previous cheetah studies reveal the variability of ecological determinants on behaviour, and the behavioural flexibility and ability of these carnivores to adapt to different environments. This advanced textbook is suitable for graduate level students as well as professional researchers in felid behavioural ecology and conservation biology. It will also be of relevance and use to conservationists, wildlife managers, and African wildlife enthusiasts.
