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.

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.

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.

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.

Mammals are the so-called "pinnacle" group of vertebrates, successfully colonising virtually all terrestrial environments as well as the air (bats) and sea (especially pinnipeds and cetaceans). How mammals function and survive in these diverse environments has long fascinated mammologists, comparative physiologists and ecologists. Ecological and Environmental Physiology of Mammals explores the physiological mechanisms and evolutionary necessities that have made the spectacular adaptation of mammals possible. It summarises our current knowledge of the complex and sophisticated physiological approaches that mammals have for survival in a wide variety of ecological and environmental contexts: terrestrial, aerial, and aquatic. The authors have a strong comparative and quantitative focus in their broad approach to exploring mammal ecophysiology. As with other books in the Ecological and Environmental Physiology Series, the emphasis is on the unique physiological characteristics of mammals, their adaptations to extreme environments, and current experimental techniques and future research directions are also considered. This accessible text is suitable for graduate level students and researchers in the fields of mammalian comparative physiology and physiological ecology, including specialist courses in mammal ecology. It will also be of value and use to the many professional mammologists requiring a concise overview of the topic.

Despite intense interest in this biologically diverse and ecologically important region, the mammals of South America are still not well known. Filling a large gap in the literature, this volume provides a survey and synthesis of current knowledge of the more than 650 species of land and marine mammals found in Ecuador, Peru, Bolivia, and Brazil.
Third in a series that reviewers have described as "state of the art" ("Journal of Biogeography") and "invaluable to anyone interested in the mammalian fauna of the Neotropics" ("Quarterly Review of Biology"), this volume follows the format of its acclaimed predecessors. Chapters present not only up-to-date taxonomic information but also ecological and behavioral characteristics, conservation status, and distribution maps for most species. Numerous illustrations are provided to assist in field and laboratory identification, including exquisite color and black-and-white plates by Fiona Reid. New to this volume are chapters contributed by experts on the mammalian fossil record of this region and on its current biodiversity and biogeography. An appendix summarizes changes to the nomenclature that have altered the scientific names used in the first two volumes.
Volumes 1 and 2 of "Mammals of the Neotropics, " which are also available, describe the mammals of Panama, Colombia, Venezuela, Guyana, Suriname, and French Guiana (volume 1) and Chile, Argentina, Uruguay, and Paraguay (volume 2). The fourth and final volume of this series will cover the mammals of Mexico and Central America.

Savannah habitats comprise an ecologically important, but ultimately fragile, ecosystem. They constitute one of the largest biomes on Earth, covering almost 20% of the land surface, and can be simply described as tropical and subtropical grasslands with scattered bushes and trees. Most savannahs occur in Africa, although smaller areas can be found in South America, India, and Australia. They form a rich mosaic of diverse ecosystems, and this book offers a concise but comprehensive introduction to their ecology, biodiversity, and conservation. The Biology of African Savannahs describes the major plants (grasses, and trees such as Acacia) and animals (mainly large mammals) that live in this habitat, and examines the biological and ecological factors that influence their population size, interactions (such as predation), and community composition. Conservation issues such as climate change, hunting, and conflict between wildlife and domestic animals are also discussed. This new edition has been updated throughout with the latest research in the field, and contains new technique boxes which introduce readers to some of the analytical methods used to study African savannahs. This accessible text is suitable for both senior undergraduate and graduate students taking courses in savannah and tropical ecology as part of a wider ecology and/or conservation biology degree programme. It will also be of relevance and use to the many professional ecologists and conservation practitioners requiring a concise but authoritative overview of the topic.

The Garden of Eden as the ideal and untouched site of life's creation persists in popular thought, even as we have uncovered a lengthy fossil record and developed a scientific understanding of evolution. The continent of Africa is a good candidate for Eden: its generally warm climate, rich vegetation, and variety of animal species lend themselves easily to such a comparison. Yet in the time since the first primates appeared millions of years ago, Africa has undergone profound alterations in physical geography, climate, and biota.

Linking the evidence of the past with that of the present, this exquisitely illustrated guide examines the evolution of the mammalian fauna of Africa within the context of dramatic changes over the course of more than 30 million years of primate presence. The book covers such topics as dating, continental drift, and global climate change and the likely motors of evolution as well as the physical evolution of the African continent, including present and past climates, and the major determinants of plant and mammal distributions. The authors discuss human evolution as a part of the larger pattern of mammalian evolution while responding to the unique interest that we have in our own past.

The meticulous reconstructions of fossil mammals in this book are the result of detailed anatomical research. Restorations of mammalian musculature and appearance take into account the affinities between fossil forms and extant species in order to make well-founded inferences about unpreserved animal attributes. Environmental reconstructions benefit from the authors' visits to more than a dozen wildlife preserves in five African countries as well as the use of an extensive database of published studies on the evolution of landscapes on the continent. A fascinating read and a visual feast, "Evolving Eden" lays the foundation for a deeper appreciation of contemporary African wildlife.

Dogs are the world's most common and widespread carnivores and are nearly ubiquitous across the globe. The vast majority of these dogs, whether owned or un-owned, pure-bred or stray, spend a large portion of their life as unconfined, free-roaming animals, persisting at the interface of human and wildlife communities. Their numbers are particularly large throughout the developing world, where veterinary care and population control are often minimal and human populations are burgeoning. This volume brings together the world's experts to provide a comprehensive, unifying, and accessible review of the effects of dogs on native wildlife species. With an emphasis on addressing how free-ranging dogs may influence wildlife management and native species of conservation concern, chapters address themes such as the global history and size of dog populations, dogs as predators, competitors, and prey of wildlife, the use of dogs as hunting companions, the role of dogs in maintaining diseases of wildlife, and the potential for dogs to hybridize with wild canid species. In addition, the potential role of dogs as mediators of conservation conflict is assessed, including the role of dogs as livestock guardians, the potential for dogs to aid researchers in locating rare wildlife species of conservation interest, and the importance of recognizing that some populations of dogs such as dingoes have a long history of genetic isolation and are themselves important conservation concerns. A common theme woven throughout this volume is the potential for dogs to mediate how humans interact with wildlife and the recognition that the success of wildlife conservation and management efforts are often underpinned by understanding and addressing the potential roles of free-ranging dogs in diverse natural ecosystems. Free-Ranging Dogs and Wildlife Conservation is aimed at professional wildlife and conservation ecologists, managers, graduate students, and researchers with an interest in human-dog-wildlife interactions. It will also be of relevance and use to dog welfare researchers, veterinary scientists, disease ecologists, and readers with an interest in the interface of domestic animals and wildlife.

Mice are used as model organisms across a wide range of fields in science today--but it is far from obvious how studying a mouse in a maze can help us understand human problems like alcoholism or anxiety. How do scientists convince funders, fellow scientists, the general public, and even themselves that animal experiments are a good way of producing knowledge about the genetics of human behavior? In Model Behavior, Nicole C. Nelson takes us inside an animal behavior genetics laboratory to examine how scientists create and manage the foundational knowledge of their field. Behavior genetics is a particularly challenging field for making a clear-cut case that mouse experiments work, because researchers believe that both the phenomena they are studying and the animal models they are using are complex. These assumptions of complexity change the nature of what laboratory work produces. Whereas historical and ethnographic studies traditionally portray the laboratory as a place where scientists control, simplify, and stabilize nature in the service of producing durable facts, the laboratory that emerges from Nelson's extensive interviews and fieldwork is a place where stable findings are always just out of reach. The ongoing work of managing precarious experimental systems means that researchers learn as much--if not more--about the impact of the environment on behavior as they do about genetics. Model Behavior offers a compelling portrait of life in a twenty-first-century laboratory, where partial, provisional answers to complex scientific questions are increasingly the norm.

How did rodent outbreaks in Germany help to end World War I? What caused the destructive outbreak of rodents in Oregon and California in the late 1950s, the large population outbreak of lemmings in Scandinavia in 2010, and the great abundance of field mice in Scotland in the spring of 2011? Population fluctuations, or outbreaks, of rodents constitute one of the classic problems of animal ecology, and in "Population Fluctuations in Rodents", Charles J. Krebs sifts through the last eighty years of research to draw out exactly what we know about rodent outbreaks and what should be the agenda for future research. Krebs has synthesized the research in this area, focusing mainly on the voles and lemmings of the Northern Hemisphere - his primary area of expertise - but also referring to the literature on rats and mice. He covers the patterns of changes in reproduction and mortality and the mechanisms that cause these changes - including predation, disease, food shortage, and social behavior - and discusses how landscapes can affect population changes, methodically presenting the hypotheses related to each topic before determining whether or not the data supports them. He ends on an expansive note, by turning his gaze outward and discussing how the research on rodent populations can apply to other terrestrial mammals. Geared toward advanced undergraduates, graduate students, and practicing ecologists interested in rodent population studies, this book will also appeal to researchers seeking to manage rodent populations and to understand outbreaks in both natural and urban settings - or, conversely, to protect endangered species.

This work provides the first overview of mammal species distributions in Africa since the Last Glacial Maximum (LGM, 18 ky) to modern time. It is derived from data published mainly in the zooarchaeological literature until 2009. During a post-doctoral project hosted in the zoological department of mammal collection at the Naturhistoriches Museum in Vienna (Austria), the occurrences of taxa in archaeological sites on the African continent were recorded in a database, integrating geographical and chronological information. This record offers the opportunity to produce a chronological atlas of mammalian distributions by presenting their occurrences on successive maps over the last 18 ky. This work is useful for zooarchaeologists dealing with one particular species by providing a bibliographical work that documents its past locations. It must be noted that fauna are mainly documented through their presence at archaeological sites and are therefore tied to the presence of humans and their activities. This may only partially reproduce their true past distribution. However, the sites offer a good coverage throughout space and time and generally reflect the extent of mammalian distributions, although the limits of their distributions may be further refined. The atlas will aid in the investigation of palaeoecological issues, such as the capacity of mammals to adapt to climatic change and respond to human disturbance in the recent past of Africa. The database also provides information that is fundamental to a better understanding of what influenced the present-day distribution, dynamism and structure of mammalian communities in Africa. By incorporating a larger temporal scale to modern ecological studies, it may help control their conservation since desiccation and human disturbance in Africa is still a worrying question for their future.

"Equine Genomics" delivers a global overview of the topic and is seamlessly edited by a leading equine genomics researcher. "Equine Genomics" is an indispensible source of information for anyone with an interest in this increasingly important field of study, including equine genomic researchers, clinicians, animal science professionals and equine field veterinarians.

Red wolves are shy, elusive, and misunderstood predators. Until the 1800s, they were common in the longleaf pine savannas and deciduous forests of the southeastern United States. However, habitat degradation, persecution, and interbreeding with the coyote nearly annihilated them. Today, reintroduced red wolves are found only in peninsular northeastern North Carolina within less than 1 percent of their former range. In The Secret World of Red Wolves, nature writer T. DeLene Beeland shadows the U.S. Fish and Wildlife Service's pioneering recovery program over the course of a year to craft an intimate portrait of the red wolf, its history, and its restoration. Her engaging exploration of this top-level predator traces the intense effort of conservation personnel to save a species that has slipped to the verge of extinction. Beeland weaves together the voices of scientists, conservationists, and local landowners while posing larger questions about human coexistence with red wolves, our understanding of what defines this animal as a distinct species, and how climate change may swamp its current habitat.

'Predators are the best wildlife managers, ' writes George Schaller. They weed out the sick and old and keep herds healthy and alert. Yet the large predators of the world have been and are still being exterminated because they are thought to harm wildlife. Schaller's award-winning work, based on three years of study in the Serengeti National Park, describes the impact of the lion and other predators on the vast herds of wildebeest, zebra, and gazelle for which the area is famous.

Otters are highly charismatic and popular animals of very considerable concern to conservationists worldwide. Written by the pre-eminent authority in the field, this book builds on the reputation of the author's landmark monograph of the European otter, Wild Otters (OUP, 1995). Furthermore, its broader scope to include all species of otter in North America as well as Europe and elsewhere leads to a deeper synthesis that greatly expands the book's overall relevance and potential readership.
Aimed at naturalists, scientists and conservationists, its personal style and generously illustrated text will appeal to amateurs and professionals alike. It emphasizes recent research and conservation management initiatives for all 13 species of otter worldwide, incorporates recent molecular research on taxonomy and population genetics, and discusses the wider implications of otter studies for ecology and conservation biology.
As well as enchanting direct observations of the animals, there is guidance about how and where to watch and study them. From otters in the British and American lakes and rivers, to sea otters in the Pacific Ocean, giant otters in the Amazon and other species in Africa and Asia, this book provides an engaging approach to their fascinating existence, to the science needed to understand it, and to the very real threats to their survival.

This book provides a comprehensive review of the evolution of traits associated with predation and predator defense for bats and all of their prey, both invertebrates (e.g. insects) and vertebrates (e.g. frogs), in the context of co-evolution. It reviews current knowledge of how echolocation and passive hearing are used by bats to hunt prey in complete darkness. Also it highlights how prey have evolved counter measures to bat echolocation to avoid detection and capture. This includes the whole range of prey responses from being active at times when bats are inactive to the use of acoustic signals of their own to interfere with the echolocation system of bats.

Seeking common principles of social evolution in different taxonomic groups, the contributors to this volume discuss eighteen groups of birds and mammals for which long-term field studies have been carried out. They examine how social organization is shaped by the interaction between proximate ecological pressures and culture"--the social traditions already in place and shaped by local and phylogenetic history.
