Research on the mental abilities of chimpanzees and bonobos has been widely celebrated and used in reconstructions of human evolution. In contrast, scant attention has been paid to the abilities of gorillas and orangutans. This volume aims to complete the picture of hominoid cognition by bringing together the work on gorillas and orangutans and setting it in comparative perspective. This book's introductory chapters set the evolutionary context for comparing cognition in gorillas and orangutans to that of chimpanzees, bonobos, and humans. The remaining chapters focus primarily on the kinds and levels of intelligence displayed by orangutans and gorillas compared to other great apes, including performances in the classic domains of tool use and tool making, imitation, self awareness, social communication, and symbol use.

Marsupial Nutrition describes the food resources used by marsupials from small insectivores to large folivores. It discusses the ways in which these animals' digestive systems and metabolism are designed to cope with foods as different as nectar and fungus, tree sap and tough perennial grasses, and insects and eucalypt foliage. Although the subject species are marsupials, the general principles of nutritional ecology and digestive strategies that are introduced at the beginning of the chapters are applicable to all mammals. Advanced undergraduates and graduate students in the areas of vertebrate zoology, nutrition, ecology, and digestive physiology will find Marsupial Nutrition particularly instructive, and wildlife biologists, veterinarians, and nutritionists will also find much of interest.

Examining mating from the male perspective, this book provides an overview of mammalian reproduction to illustrate the important role that male desire plays in the life of mammals. Written in a conversational style that will appeal to those without specialist knowledge of the field, it begins with a broad overview of sexual reproduction in mammals, explaining the importance of mixing genes, sexual selection and the concept of mating seasons. Subsequent chapters examine some of the most important aspects in detail including mating behaviour, the structure and function of the male organs of reproduction and their physiological control and modes of copulation. A final chapter considers human reproduction, explaining how our physical and social evolution have contributed to the development of sexual behaviour that is markedly different to that of other mammals, due in particular to the absence of oestrus and seasonality in the human female.

In this book, field and laboratory researchers show that the Great Apes are capable of thinking at symbolic levels, traditionally considered uniquely human. They show these high-level abilities in both social and ecological domains, including tool use, imitation, pretense, self-awareness, deception, consolation, teaching and proto-culture itself. Here, contributors emphasize the mechanisms involved in building these abilities--especially the lengthy developmental and "enculturation" processes--suggesting changes to current views on how primate and human intelligence have evolved. Researchers and professionals in the fields of primatology, animal behavior, anthropology, linguistics, and cognitive psychology will find much useful information in this book.

How can the intelligence of monkeys and apes, and the huge brain expansion which marked human evolution be explained? In 1988, Machiavellian Intelligence was the first book to assemble the early evidence suggesting a new answer: that the evolution of intellect was primarily driven by selection for manipulative, social expertise within groups where the most challenging problem faced by individuals was dealing with their companions. Since then a wealth of new information and ideas has accumulated. This new book will bring readers up to date with the most important developments, extending the scope of the original ideas and evaluating them empirically from different perspectives. It is essential reading for reseachers and students in many different branches of evolution and behavioural sciences, primatology, and philosophy.

The first work to illustrate and describe every living species of mammal on Earth. Volume 2 is devoted to Hoofed Mammals. The Handbook of the Mammals of the World (HMW) will be an unprecedented reference work for the Class Mammalia. This series of eight volumes will describe every currently recognized mammal species, along with an overview of each mammalian family. It will provide up-to-date information on the systematic relationships, natural history, ecology, and current conservation status for all mammals. Every species will be illustrated and each chapter will also include many color photographs. HMW will provide comprehensive worldwide coverage by involving an international group of expert authors.

What special qualities of mind set the great apes apart from other nonhuman primates, and indeed from ourselves? In this book, field and laboratory researchers show that the great apes have high level abilities in both social and ecological domains, including tool use, pretense, self-awareness, deception, consolation, teaching and culture itself. Great apes are also shown to be capable of thinking at symbolic levels, traditionally considered to be uniquely human. Here, the mechanisms involved in building these abilities - especially the lengthy developmental and 'enculturation' processes - are emphasized, showing how new discoveries are changing views on how primates and human intelligence evolved. This book is for anyone interested in current research and theoretical views of great ape cognition.

A young woman follows her fiance to war-torn Congo to study extremely endangered bonobo apes-who teach her a new truth about love.
In 2005 Vanessa Woods accepted a marriage proposal from a man she barely knew and agreed to join him on a research trip to the war-torn Democratic Republic of Congo. Settling in at a bonobo sanctuary in Congo's capital, Vanessa and her fiance entered the world of a rare ape with whom we share 98.7 percent of our DNA and who live in a peaceful society in which females are in charge, war is nonexistent, and sex is as common and friendly as a handshake.
A fascinating memoir of hope and adventure, "Bonobo Handshake" traces Vanessa's self-discovery as she finds herself falling deeply in love with her husband, the apes, and her new surroundings in this true story of revelation and transformation in a fragile corner of Africa.

In this unique book, Sir Donald Harrison draws on his wide-ranging experience as a surgeon and comparative anatomist to produce an authoritative and detailed account of the anatomy and physiology of the mammalian larynx. His investigation of the larynx has involved the study of over 1400 specimens of mammalian larynges from around the world, as well as using data from his own clinical experiences. The comparative morphology of the larynx is discussed from a developmental and functional perspective and the involvement of the larynx in respiration, locomotion and vocalisation is highlighted. Throughout the book the relationship of structure to function is drawn out and the clinical relevance of features of the human larynx is emphasised. This book will be an invaluable reference for all researchers and clinicians involved in laryngology as well as for anatomists, zoologists and anaesthesiologists.

This examination of a depopulated species, the North American bison, provides insights into the past and present behaviour and ecology of what was once the continent's largest terrestrial mammal. The authors' research, conducted over a five-year period, attempts to resolve such questions as: what happens when only a small proportion of the male of a species mate?; why do animals in particular areas experience morphological malformations?; and how much genetic diversity has been lost since the 19th century? The study also discusses the consequences of mating failures, lineage differences in growth and birth synchrony. It explores behavioural ecology, mate choice, the conservation of ecosystems and the management of endangered species.

Colobine monkeys have a unique digestive system, analogous to that of ruminants, which allows them to exploit foliage as a food source. This gives them a niche in Old World forests where they are often the only abundant medium-sized arboreal folivorous mammal. From a possible Miocene origin, Colobine monkeys have radiated into a wide variety of forms inhabiting a range of tropical woodlands in Africa and Asia. Most of the extant species have been subject to long term field studies, but until this book, no synthesis of work on this group has been available. The central theme is that of adaptive radiation, showing how the special features of Colobine anatomy interacted with a range of ecosystems to produce the distinctive species of today. The book also discusses parallels with other mammalian groups.

However well the anatomy of the gastrointestinal tracts of a wide range of mammals are described and quantified, there can be no real explanation of observed patterns without consideration of the mechanical and chemical properties of the food consumed, and digestive stages involved in its processing. This book aims to integrate findings from the many different types of investigations of mammalian digestive systems into a coherent whole. Using the themes of food, form and function, researchers discuss models of digestive processes, linking this with evolutionary aspects of food utilization. Macroscopic and ultrastructural studies of the gastrointestinal tract are also presented, as are physiological, ecological and biochemical aspects of the digestion of different food types. The book ends with an integrative chapter, bringing together the themes running through the earlier sections.

The Australian bush holds many secrets, and one of its biggest is about to be revealed... It's one of Australia's greatest mysteries. For decades there has been talk of big cats roaming the Australian bush. These large cats - predominantly black - have only afforded their witnesses fleeting glimpses, and left behind tantalising clues: scraps of fur, a paw print or three, unusually large scats, and livestock carcasses surgically dismembered and picked clean of flesh. In their wake, they leave carnage and bewilderment: What are they? How did they get here? We don't just ask the questions, we seek the answers, and what we have found will intrigue the sceptic and the believer alike. Big cat sightings have been occurring with greater frequency across the country in the past 20 years, leading to speculation there may be a breeding colony of large cats in Australia. Australia isn't the only antipodean country touched by the black cat mystery. Our book also dedicates a chapter to the profusion of sightings and speculation in neighbouring New Zealand, documenting reports right up until 2009 and sharing for the first time highlights from the unpublished manuscript of New Zealand's first big cat hunter. Flesh-and-blood or flight of fancy? Exotic pest, mutant feral or 'extinct' marsupial lion? Join us as we explore one of Australia's greatest mysteries.

This collection of articles is completely and explicitly devoted to the new field of comparative developmental evolutionary psychology--that is, to studies of primate abilities based on frameworks drawn from developmental psychology and evolutionary biology. These frameworks include Piagetian and neo-Piagetian models as well as psycholinguistic ones. The articles in this collection--originating in Japan, Spain, Italy, France, Canada, and the United States--represent a variety of backgrounds in human and nonhuman primate research. The authors focus on such areas as the nature of culture, intelligence, language, and imitation; the differences among species in mental abilities and developmental patterns; and the evolution of life histories and of mental abilities and their neurological bases.

Rodents are the predominant experimental animals found in life-sciences research laboratories. The body temperature of a rodent is markedly affected by surgical, chemical or environmental manipulation. Because temperature regulation is controlled essentially by a 'holistic' regulatory system, meaning that its responses affect the activities of all other psychological and behavioural processes, it is clear that researchers working with rodents must be familiar with thermoregulatory physiology. With the help of extensive data tables and figures, this book explains the key facets of rodent thermal physiology, including neurological control and gender and intraspecies variations. There is a novel chapter on the effects of trauma, toxic chemicals and other factors. The book should therefore find use in government, academic or industrial laboratories whose researchers are working with rodents.

Despite its remote and seemingly rigorous environment, the Antarctic is the world's most important habitat for seals, currently supporting more seals than all other parts of the world combined. As various national Antarctic programmes were established to study these animals, the need to standardize techniques became apparent. This book, arising from work by the Scientific Committee on Antarctic Research (Group of Specialists on Seals), gives a detailed account of well-tried and, where possible, agreed methodologies, techniques, procedures and rationale for the collection and initial analysis of data on the biology and population ecology of Antarctic seals. This volume will not only help facilitate comparisons between different regions of Antarctica, but will also provide a guide for those studying seals in other parts of the world and those carrying out research on other large mammal species.

The chimpanzee of all other living species is our closest relation, with whom we last shared a common ancestor about five million years ago. These African apes make and use a rich and varied kit of tools, and of the primates they are the only consistent and habitual tool-users and tool-makers. Chimpanzees meet the criteria of a culture as originally defined for human beings by socio-cultural anthropologists. They show sex differences in using tools to obtain and to process a variety of plant and animal foods. The technological gap between chimpanzees and human societies that live by foraging (hunter-gatherers) is surprisingly narrow at least for food-getting. Different communities of wild chimpanzees have different tool-kits and not all of this regional and local variation can be explained by the demands of the physical and biotic environments in which they live. Some differences are likely to be customs based on socially derived and symbolically encoded traditions. This book describes and analyzes the tool-use of humankind's nearest living relation. It focuses on field studies of these apes across Africa, comparing their customs to see if they can justifiably be termed cultural. It makes direct comparisons with the material culture of human foraging peoples. The book evaluates the chimpanzee as an evolutionary model, showing that chimpanzee behavior helps us to infer the origins of technology in human prehistory.

The Asian elephant has had a unique cultural association with people. Unfortunately, elephants and people have also been in conflict, resulting in the decline in elephants throughout their former range in Southern Asia. This book provides an ecological analysis of elephant-human interaction and its implication for the conservation of elephants. The foraging habits of elephants and their impact on vegetation are considered, along with the interactions that occur between elephants and humans. The ecological data provide the basis for recommendations on elephant conservation and management, keeping in view the socio-economic imperatives of the Asian region. This first comprehensive account of Asian elephant ecology will be of particular interest to conservation biologists and mammalogists.

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. Originally published in 1976. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

This book presents an alternative to conventional ideas about the evolution of the human intellect. Instead of placing top priority on the role of tools, the pressure for their skillful use, and the related importance of interpersonal communication as a means for enhanced cooperation, this volume explores quite a different idea-- that the driving force in the evolution of human intellect was social expertise--a force which enabled the manipulation of others within the social group, who themselves are seen as posing the most challenging problems faced by primitive humans. The need to outwit one's clever colleagues then produces an evolutionary spiraling of "Machiavellian intelligence." The book forms a complete and self-contained text on this fast-growing topic. It includes the origins of the basic premise and a wealth of exciting developments, described by an international team of authors from the fields of anthropology, psychology, and zoology. An evaluation of more traditional approaches is also undertaken, with a view to discovering to what extent Machiavellian intelligence represents a complementary concept or one that is truly an alternative. Readers and students will find this fascinating volume carries them to the frontiers of scientific work on the origin of human intellect.

Marsupials differ from most other mammals in their method of reproduction, in that they have chosen, in an evolutionary sense, to develop lactation rather than placentation for the nurture of their young. The neonate is therefore born with a mixture of advanced and embryonic characters, and yet is readily accessible within the pouch, providing a unique system for the study of the ontogeny of various physiological and endocrinological parameters. Marsupials are therefore ideal animals for research into mammalian reproductive physiology. The results of this exciting new research are summarized in this book by two of the foremost workers in the field. Individual chapters analyse the genetic and hormonal control of sexual differentiation, male and female reproductive structures and their functions, the role of the corpus luteum in the oestrous cycle and pregnancy, the hormonal control of embryonic diapause and the role of the marsupial placenta in the development of the embryo. This book is more than just a straightforward review of marsupial reproduction for its detailed analyses and broad comparative coverage will attract mammalogists and reproductive physiologists with a wide range of research interests.

Grizzly bears can climb trees; black bears can be brown - or even white, and some coastal bears will not hibernate at all. These facts, and the vibrant photographs of bears, underscore The Bear Man's true message, which is: learn how to behave around bears; know proper 'bear manners' and you - and the bear - will survive an encounter. Armed with just bear spray and the knowledge he has acquired in nearly forty years of studying bears in their natural habitat, Keith Scott hikes the wilds of Canada and Alaska, looking for bears, living where they live. His adventures and experience have made him a specialist on bear habitats and behaviour, and his commitment is to teach people about these misunderstood and magnificent animals.
