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.

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.

Hans Thewissen, a leading researcher in the field of whale paleontology and anatomy, gives a sweeping first-person account of the discoveries that brought to light the early fossil record of whales. As evidenced in the record, whales evolved from herbivorous forest-dwelling ancestors that resembled tiny deer to carnivorous monsters stalking lakes and rivers and to serpentlike denizens of the coast. Thewissen reports on his discoveries in the wilds of India and Pakistan, weaving a narrative that reveals the day-to-day adventures of fossil collection, enriching it with local flavors from South Asian culture and society. The reader senses the excitement of the digs as well as the rigors faced by scientific researchers, for whom each new insight gives rise to even more questions, and for whom at times the logistics of just staying alive may trump all science. In his search for an understanding of how modern whales live their lives, Thewissen also journeys to Japan and Alaska to study whales and wild dolphins. He finds answers to his questions about fossils by studying the anatomy of otters and porpoises and examining whale embryos under the microscope. In the book's final chapter, Thewissen argues for approaching whale evolution with the most powerful tools we have and for combining all the fields of science in pursuit of knowledge.

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.

Mammalian skull structure is notably diverse; however at a basic level the jaw mechanism is remarkably similar, if not essentially the same, in the majority of mammals. Using simple models that are compared with real animals at every step, this book examines the basic structural features of the mammalian jaw mechanism from a mechanical point of view. It explores how the mechanical constraints placed on the jaw have contributed to the evolution of an efficient basic structure, used by many mammals, which precludes mechanical difficulties and uses a minimum amount of bone tissue. Throughout the book the emphasis is on conceptual understanding, with explanations linked together to form a complete story that can be applied to both fossil and extant mammals. Summarising over forty years of research from one of the leading pioneers in 3D jaw mechanics, this is a must-have for anyone interested in mammalian jaw morphology.

This title is the first stand-alone and definitive account of the cetaceans of the oceanic region from the equator to Antarctica, and between the longitudes of 20 Degrees W and 80 Degrees E - a region that includes almost two-thirds of the world's marine cetacean species. In the fascinating accounts of 51 species of whales and dolphins (and one porpoise), information for this region is comprehensively summarised, allowing Peter Best to give us the benefit of his extensive knowledge and of the wealth of unpublished information he has accumulated during his 40 years of studying these creatures. Approximately 100 illustrations have been created in colour for this book by world-renowned marine mammal illustrator Pieter Folkens. Colour photographs of the living animal portray the 'jizz' of each species and specific coloration or behavioural features.

Orcas are the most profitable and controversial display animal in history, and since the release of the documentary Blackfish in 2013, millions around the world have focused on their plight. Yet no historical account has explored how we came to care about killer whales in the first place. In Orca, Jason Colby tells the exhilarating and often heartbreaking story of how people came to love the ocean's greatest predator. Historically reviled as dangerous pests, killer whales were dying by the hundreds, even thousands, by the 1950s-the victims of whalers, fishermen, and even the US military. In the Pacific Northwest, fishermen shot them, scientists harpooned them, and the Canadian government mounted a machine gun to eliminate them. But that all changed in 1965, when a Seattle entrepreneur named Ted Griffin became the first person to swim and perform with a captive killer whale. The show was a hit, and he began capturing and selling others, including Sea World's first "Shamu." Over the following decade, live display transformed popular and scientific views of Orcinus orca. The public embraced killer whales as charismatic and friendly while scientists enjoyed their first access to live orcas. In the Pacific Northwest, these captive encounters reshaped regional values and helped drive environmental activism, including Greenpeace's anti-whaling campaigns. Yet even as Northwesterners taught the world to love whales, they came to oppose their captivity. So when Sea World attempted to catch its own killer whales, Northwesterners would fight for the freedom of a marine predator that had become a regional icon. With access to previously unavailable documents and interviews, Colby offers the definitive history of how the feared and despised "killer" became the beloved "orca" and what that means for our relationship with the ocean and its creatures.

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.

Are humans by nature hierarchical or egalitarian? "Hierarchy in the Forest" addresses this question by examining the evolutionary origins of social and political behavior. Christopher Boehm, an anthropologist whose fieldwork has focused on the political arrangements of human and nonhuman primate groups, postulates that egalitarianism is in effect a hierarchy in which the weak combine forces to dominate the strong.

The political flexibility of our species is formidable: we can be quite egalitarian, we can be quite despotic. "Hierarchy in the Forest" traces the roots of these contradictory traits in chimpanzee, bonobo, gorilla, and early human societies. Boehm looks at the loose group structures of hunter-gatherers, then at tribal segmentation, and finally at present-day governments to see how these conflicting tendencies are reflected.

"Hierarchy in the Forest" claims new territory for biological anthropology and evolutionary biology by extending the domain of these sciences into a crucial aspect of human political and social behavior. This book will be a key document in the study of the evolutionary basis of genuine altruism.

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.

Edward G. Jones??? The Thalamus is one of the most cited publications in neuroscience. Now more than 20 years on from its first printing, the author has completely rewritten his landmark volume, incorporating the numerous developments in research and understanding of the mammalian thalamus. As a leading authority on thalamus biology and function, Edward G. Jones shows how knowledge of the thalamus has developed with the introduction of new technologies and ideas. The author's photographic skills are exhibited in brilliant preparations of thalamic structure in a wide range of common and uncommon species. The Thalamus is both an up-to-date scientific review of virtually all aspects of forebrain function and a work of immense neuroscientific scholarship. It forms an essential reference for neuroanatomists, neurophysiologists, molecular neurobiologists, developmental neurobiologists and clinicians its deep historical perspective will be of value to historians of science.

Chimpanzees fascinate people for many reasons. We are struck by the apes' resemblance to humanity, as seen in their use of tools and their complex social lives, and we are moved by the threats that human activity poses to them. Our awareness of our closest living relatives testifies to the efforts of the remarkable people who study these creatures and work to protect them. What motivates someone to dedicate their lives to chimpanzees? How does that reflect on our own species? This book brings together a range of chimpanzee experts who tell powerful personal stories about their lives and careers. It features some of the world's preeminent primatologists-including Jane Goodall and Frans de Waal-as well as representatives of a new generation from varied backgrounds. In addition to field scientists, the book features anthropologists, biologists, psychologists, veterinarians, conservationists, and the director of a chimpanzee sanctuary. Some grew up in the English countryside, others in villages in Congo; some first encountered chimpanzees in a zoo, others in the forests surrounding their homes. All are united by a common purpose: to study and understand chimpanzees in order to protect them in the wild and care for them in zoos and sanctuaries. Contributors share what inspired them, what shaped their career choices, and what motivates them to strive for solutions to the many challenges that chimpanzees face today.

The synthesis of the Aquatic Biodiversity and Ecosystems Conference (ABEC) 2015, which was held to assess scientific progress over the past twnety-five years, this book provides a comprehensive and global review of work since the 1992 publication of Plant-Animal Interactions in the Marine Benthos. Taking a regional and, where appropriate, habitat perspective, it considers sites of coastal biodiversity from around the world to incorporate a global approach. The volume analyses abiotic and biotic interactions, and the factors determining distribution patterns, community structure and ecosystem functioning of coastal systems. It explores themes of how phylogeography and biogeographic process influence assemblage composition, and hence drive community structure and the respective roles of environmental factors and biological interactions, with the overall goal to establish how general are the processes in different regions and habitats. For researchers, graduate students and academics studying coastal ecosystems, with interest for conservation practitioners managing areas of high biodiversity.

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 behaviour of domesticated animals is a subject of great importance to students of animal behaviour and veterinary medicine, as well as interested pet owners. This book presents an engaging overview of the behaviour of the domestic cat, adopting both a mechanistic and functional approach. Physiological, developmental and psychological aspects are addressed, including domestication, the development of the senses, learning, communication and feeding behaviour. The authors build on these themes to discuss social behaviour, hunting and predation, cat-human interactions and welfare. Fully updated throughout, this new edition also includes two new chapters on behavioural disorders due to pathologies and from misdirected natural behaviour. It is an essential source of cat behaviour information for students, ethologists, veterinarians and pet owners.

Understanding the complex relationships between humans and the natural world is essential for achieving environmental sustainability and improving human well-being, yet many studies are unable to reveal complex interactions and hidden trends. This is the first book to synthesize the findings and approaches of long-term integrated research in a model coupled human and natural system, and to illustrate their applications to regional, national, and global scales. It features a classic long-term interdisciplinary research project in the Wolong Nature Reserve of China, which contains one of the largest wild populations of the world-famous endangered giant pandas. Bringing together a team of contributors from both the natural and social sciences, this book explores how a long-term interdisciplinary and model system approach is essential to uncover the common patterns and mechanisms of coupled systems, to develop ideas and methods for studying and managing other coupled systems, and ultimately to contribute to the development of theories about coupled systems for sustainability. Pandas and People will be essential reading for scholars interested in the interface of the natural and social sciences, including ecologists, conservation biologists, environmental scientists, sustainability scientists, wildlife biologists, forest scientists, sociologists, anthropologists, economists, and political scientists. It will also be a valuable reference for policy makers, natural resource managers, and graduate students.

Sir Stamford Raffles came across an unnamed new species in 1821 when he was documenting natural history in Singapore. This elusive primate, the Raffles' banded langur, was later named after him. This book is a one-stop resource for everything we know about the critically endangered primate that is only found in Singapore and Malaysia, including its distribution, diet, family structure, infant development, threats and conservation. The Raffles' banded langur is a large but slender-bodied monkey with black fur and white bands, while the infants are born with white fur and black bands. Exclusive high-quality photographs of the langurs are featured with family trees illustrating individually-named langurs. Interesting anecdotes about their personalities and behaviours are narrated. Living high up in the tree canopy, they eat a variety of local produce and exotic plants, from the red, juicy rambutans, stinky petai beans, to leafy angsana, perfumed wild cinnamon flowers and large sea almond fruits. This book showcases the diverse habitats of the Raffles' banded langurs, bringing us from the freshwater swamp forest in Singapore to the steep slopes of Gunung Lambak and the primary rainforests of Endau Rompin National Park in Johor, Malaysia. The book also highlights the cross-border conservation efforts and future plans to safeguard the long-term survival of the Raffles' banded langur, and promotes a better understanding and appreciation of our shared natural heritage.

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.

For centuries whales have captured our imaginations and ignited our emotions. We have revered and mythologised them, hunted them to the brink of extinction and passionately protected them. But how much do we really know about whales? Based on the hugely popular, internationally touring exhibition Whales Tohora (a.k.a. Whales: Giants of the Deep), this all-new book brings these majestic marine mammals and their underwater world to life, with a special focus on the whales and dolphins of the South Pacific. From the first richly illustrated, entertaining chapter, readers are immersed in the salty sea, the home of the whales, to explore their amazing diversity, biology and adaption to life in the oceans. Throughout the book, literally hundreds of breath-taking photographs, historical pictures, astonishing facts and figures and informative illustrations and diagrams bring the whale world to life. Here, too, are stories from people whose lives have been inextricably linked with whales - from legendary South Pacific whale riders to international whale scientists to conservationists to former whalers and their families.Powerfully, Whales Tohora combines storytelling, science, and culture to tell the story of the relationship between the humans and these fascinating creatures throughout history and into the future.

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.

Nearly half the world's primate species use flooded habitats at one time or another, from swamp-going Congo gorillas and mangrove-eating proboscis monkeys, to uacaris in Amazonian riverside forests. This first-ever volume on the subject brings together experts from around the world in a ground breaking volume spanning fossil history, current biology and future research and conservation priorities. Flooded habitats are a vital part of tropical biology, both for the diversity of the species they house, and the complexity of their ecological interactions, but are often completely overlooked. This book will set the stage for a new wave of research on primates in these extraordinarily productive and highly threatened areas, and is ideal for researchers and graduate students in primatology, zoology, ecology, and conservation.

Animals that must hunt and kill for at least part of their living are inherently interesting to many people and the role that carnivores play in biological communities attract interest from ecologists and conservation biologists. Conflicts with human activities stimulate continual debates about the management of carnivore populations, and throughout the world people seek workable solutions for human/carnivore coexistence. This concise yet authoritative handbook describes research methods and techniques for the study and conservation of all terrestrial carnivore species. Particular attention is paid to techniques for managing the human/carnivore interface. Descriptions of the latest methodologies are supported by references to case studies, whilst dedicated boxes are used to illustrate how a technique is applied to a specific land cover type, species, or particular socio-economic context. The book describes the most recent advances in modelling the patterns of animal distributions, movements, and use of land cover types, as well as including the most efficient methods to trap, handle, and mark carnivores. Carnivores are biogeographically diverse and whilst extensive scientific research has investigated many aspects of carnivore biology, not all species have been equally covered. This book is unique in its intention to provide practical guidance for carrying out research and conservation of carnivores across all species and areas of the world.
