This book describes one of our closest relatives, the orangutan, and the only extant great ape in Asia. It is increasingly clear that orangutan populations show extensive variation in behavioural ecology, morphology, life history, and genes. Indeed, on the strength of the latest genetic and morphological evidence, it has been proposed that orangutans actually constitute two species which diverged more than a million years ago - one on the island of Sumatra the other on Borneo, with the latter comprising three subspecies.
This book has two main aims. The first is to carefully compare data from every orangutan research site, examining the differences and similarities between orangutan species, subspecies, and populations. The second is to develop a theoretical framework in which these differences and similarities can be explained. To achieve these goals the editors have assembled the world's leading orangutan experts to rigorously synthesize and compare the data, quantify the similarities or differences, and seek to explain them.
Orangutans is the first synthesis of orangutan biology to adopt this novel, comparative approach. It analyses and compares the latest data, developing a theoretical framework to explain morphological, life history, and behavioural variation. Intriguingly, not all behavioural differences can be attributed to ecological variation between and within the two islands; relative rates of social learning also appear to have been influential. The book also emphasizes the crucial impact of human settlement on orangutans and looks ahead to the future prospects for the survival of critically endangered natural populations.

Current dominant thinking and practice in the private and public sectors asserts that peoples' development needs are in conflict with, or mutually exclusive to, the need to conserve the biosphere on which we depend. Consequently, we are asked to either diminish development in the name of conservation or diminish conservation in the name of development. Efforts to identify complementary objectives, or mutually acceptable trade-offs and compromises indicate, however, that this does not always have to be the case. This first volume in the State of the Apes series draws attention to the evolving context within which great ape and gibbon habitats are increasingly interfacing with extractive industries. Intended for a broad range of policy makers, industry experts, decision makers, academics, researchers and NGOs, these publications aim to influence debate, practice and policy, seeking to reconcile ape conservation and welfare, and economic and social development, through objective and rigorous analysis.

In 1953 a young female Japanese macaque called Imo began washing sweet potatoes before eating them, presumably to remove dirt and sand grains. Soon other monkeys had adopted this behaviour, and potato-washing gradually spread throughout the troop. When, three years after her first invention, Imo devised a second novel foraging behaviour, that of separating wheat from sand by throwing mixed handfuls into water and scooping out the floating grains, she was almost instantly heralded around the world as a 'monkey genius'. Imo is probably the most celebrated of animal innovators. In fact, many animals will invent new behaviour patterns, adjust established behaviours to a novel context, or respond to stresses in an appropriate and novel manner.

Innovation is an important component of behavioural flexibility, vital to the survival of individuals in species with generalist or opportunistic lifestyles, and potentially of critical importance to those endangered or threatened species forced to adjust to changed or impoverished environments. Innovation may also have played a central role in avian and primate brain evolution. Yet until recently animal innovation has been subject to almost complete neglect by behavioural biologists, psychologists, social learning researchers, and conservation-minded biologists.

This collection of stimulating and readable articles by leading scientific authorities is the first ever book on 'animal innovation', designed to put the topic of animal innovation on the map and heighten awareness of this developing field.

The chimpanzees are the closest living evolutionary relatives to our own species, Homo sapiens. As such, they have long exerted a fascination over those with an interest in human evolution, and human uniqueness. Chrisophe Boesch and Hedwige Boesch-Acherman undertook an incredible observational study of a group of wild chimpanzees in Cote D'Ivoire, spending some fifteen years in the West African forest with them. This fascinating book is the result of these years of painstaking research among the chimps. Chimpanzee behaviour is documented here in all its impressive diversity and variety, and placed within the broader context of research in behavioural ecology. The authors also succeed in shedding light on some of the central questions around the evolutionary relationships between the primates, and in particular the affinity between chimpanzees and humans.

Building on the success of the first edition and bringing together contributions from a range of experts in the field, the second edition of this guide to research on wild primates covers the latest advances in the field, including new information on field experiments and measuring behaviour. It provides essential information and advice on the technical and practical aspects of both field and laboratory methods, covering topics such as ethnoprimatology; remote sensing; GPS and radio-tracking; trapping and handling; dietary ecology; and non-invasive genetics and endocrinology. This integrated approach opens up new opportunities to study the behavioural ecology of some of the most endangered primates and to collect information on previously studied populations. Chapters include methodological techniques; instructions on collecting, processing and preserving samples/data for later analysis; ethical considerations; comparative costs; and further reading, making this an invaluable tool for postgraduate students and researchers in primatology, behavioural ecology and zoology.

Comparative Neuropsychology is a collection of state-of-the-art essays by some of the world's leading neuropsychologists. It is prepared as a tribute to the late George Ettlinger, one of the leading figures in comparative neuropsychology research over the last 40 years, and reflects current research in the many areas where Ettlinger made a particular contribution to our understanding. Taking as their starting point the assumption that the human brain shares many of its most important functional systems with its primate relatives, the authors take a comparative evolutionary approach to understanding human cognition and brain function. The book's fifteen chapters cover a wide range of subject areas, including memory, visual and somatosensory perception, motor control, attention, cross-modality integration, interhemispheric transmission, and behavioural intelligence. The final chapters of the book critically discuss questions basic to the comparative enterprise: whether we can in fact apply concepts derived from human cognitive psychology to primate neuropsychology, and whether there are evolutionary discontinuities in cortical brain structure among the higher primate species. One of the first and most comprehensive books to be written on the topic, Comparative Neuropsychology forms a fascinating and wide-ranging collection. It will be read by undergraduate and post-graduate students in psychology, neuroscience, and neuropsychology, as well as researchers in those areas.

The inspiration for the film The Dark Divide starring David Cross and Debra Messing, one of America's most esteemed natural history writers takes to the hills in search of Bigfoot-and finds the wildness within ourselves. Awarded a Guggenheim Fellowship to investigate the legends of Sasquatch, Yale-trained ecologist Dr. Robert Pyle treks into the unprotected wilderness of the Dark Divide near Mount St. Helens, where he discovers both a giant fossil footprint and recent tracks. On the trail of what he thought was legend, he searches out Indians who tell him of an outcast tribe, the Seeahtiks, who had not fully evolved into humans. A handful of open-minded biologists and anthropologists counter the tabloids Pyle studies, while rogue Forest Service employees and loggers swear of a vast conspiracy to deep-six true stories of unknown, upright hominoid apes among us. He attends Sasquatch Daze, where he meets scientists, hunters, and others who have devoted their lives to the search, only to realize that "these guys don't want to find Bigfoot they want to be Bigfoot!" Since its original publication, the author's fresh experiences and finds have been added to his original work through an updated chapter. With an evaluation of recent DNA evidence from Bigfoot hair and scat, the study of speech phonemes in the "Sierra Sounds" purported Bigfoot recordings, an examination of the impact of the wildly popular Animal Planet series Bigfoot Hunters, the reemergence of the famous Bob Gimlin into the Bigfoot community, and more, Walking With Bigfoot keeps every Bigfoot enthusiast's mind wide open to one of the biggest questions in the land and brings Pyle's work on the "legend" of Bigfoot into the new century.

The propagation of wild animals in captivity is playing an increasingly important role in the conservation of species. This is particularly true of primates, many of which are threatened or endangered in their natural habitat. Unfortunately, primate mortality during the neonatal period is often high in captivity, often because of suboptimal management. Significant improvements in infant survival can be made with a better knowledge of neonatal biology and rearing procedures. The aim of this book is to provide a reference text on the normal growth of 18 primate species commonly held in captivity for propagation or research, and on the housing, feeding, management, and preventative medicine techniques that enable this normal growth. Up-to-date information, scattered widely through the scientific literature, is here gathered together and presented in an easily accessible form for those involved in rearing primates in captivity.

Scientific studies of monkeys, apes, and other nonhuman primates began just over 50 years ago. Since then tens of thousands of hours of observation have been made on these animals in the wild and in captivity. The chief rationale for scientific primatology has always been the belief that important insights into human behaviour and society could be gained through studies of our evolutionary kin.

This book reviews what we have learned. Distinguished researchers outline primatological insights in six areas: sex, parenting, behavioural development, aggression/dominance, culture and kinship. The chapters show how primates have been used as simplified models of human behaviour and how they have contributed to scenarios of human evolution. Lay readers, students, and specialists alike will find this a readable and useful compendium of the findings of scientific primatology. Covering topics from orgasm to ontogeny, parental investment to penis size, and kinship to culture, this book summarizes what studying monkeys and apes has taught us about ourselves.

As our closest evolutionary relatives, nonhuman primates are integral elements in our mythologies, diets and scientific paradigms, yet most species now face an uncertain future through exploitation for the pet and bushmeat trades as well as progressive habitat loss. New information about disease transmission, dietary and economic linkage, and the continuing international focus on conservation and primate research have created a surge of interest in primates, and focus on the diverse interaction of human and nonhuman primates has become an important component in primatological and ethnographic studies. By examining the diverse and fascinating range of relationships between humans and other primates, and how this plays a critical role in conservation practice and programs, Primates Face to Face disseminates the information gained from the anthropological study of nonhuman primates to the wider academic and non-academic world.

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 Metaphysics of Apes, first published in 2005, traces the discovery and interpretation of the human-like great apes and the ape-like earliest ancestors of present-day humans. It shows how, from the days of Linnaeus to recent research, the sacred and taboo-ridden animal-human boundary was time and again challenged and adjusted. The unique dignity of humans, a central idea and value in the West, was, and to some extent still is, centrally on the minds of taxonomists, ethnologists, primatologists, and archaeologists. It has guided their research to a considerable extent. The basic presupposition was that humans are not entirely part of nature but, as symbolizing minds and as moral persons, transcend nature. This book was the first to offer an anthropological analysis of the burgeoning anthropological disciplines in terms of their own cultural taboos and philosophical preconceptions.

This book offers a valuable resource, reviewing the current state of knowledge concerning the pathology and epidemiology of infectious diseases in both captive and wild monkeys. The One Health concept forms the framework of all chapters. The multidisciplinary team of authors addresses neglected diseases caused by the three major pathogen groups - bacteria, viruses, and parasites. Moreover, the volume discusses key virulence factors such as the evolution of antibiotic resistance, and the ecological drivers of and human influence on pathogen transmission. Demonstrating how researchers working on monkeys diseases are increasingly thinking outside the box, this volume is an essential reference guide to the field of One Health and will serve as an asset for stakeholders in conservation, healthcare and research organizations that face the challenge of moving beyond classical human oriented approaches to health.

Sexual Selection in Primates provides an up-to-date account of all aspects of sexual selection in primates, combining theoretical insights, comprehensive reviews of the primate literature and comparative perspectives from relevant work on other mammals, birds and humans. Topics include sex roles, sexual dimorphism in weapons, ornaments and armaments, sex ratios, sex differences in behaviour and development, mate choice, sexual conflict, sex-specific life history strategies, sperm competition and infanticide. The outcome of the evolutionary struggle between the sexes, the flexibility of roles and the leverage of females are discussed and emphasised throughout. Sexual Selection in Primates is aimed at graduates and researchers in primatology, animal behaviour, evolutionary biology and comparative psychology.

Discover this remarkable account of twenty-one years in remote Kenya with a troop of Savannah baboons from the New York Times bestselling author of Behave. 'One of the best scientist-writers of our time' Oliver Sacks Brooklyn-born Robert Sapolsky grew up wishing he could live in the primate diorama in the Museum of Natural History. At school he wrote fan letters to primatologists and even taught himself Swahili, all with the hope of one day joining his primate brethren in Africa. But when, at the age of twenty-one, Sapolky's dream finally comes true he discovers that the African bush bears little resemblance to the tranquillity of a museum. This is the story of the next twenty-one years as Sapolsky slowly infiltrates and befriends a troop of Savannah baboons. Alone in the middle of the Serengeti with no electricity, running water or telephone, and surviving countless scams, culinary atrocities and a surreal kidnapping, Sapolsky becomes ever more enamoured with his adopted baboon troop - unique and compelling characters in their own right - and he returns to them summer after summer, until tragedy finally prevails. 'A Primate's Memoir is the closest the baboon is likely to come - and it's plenty close enough - to having its own Iliad' New York Times Review of Books Exhilarating, hilarious and poignant, A Primate's Memoir is a uniquely honest window into the coming-of-age of one of our greatest scientific minds.

Gorillas, one of our closest living relatives, are the largest living primates, and teeter on the brink of extinction. This study offers the first comparative perspective on gorilla populations throughout their natural range, and covers all known subspecies. Discussing phylogeny, evolution, functional morphology, behavioral ecology and conservation biology, this multidisciplinary work will be essential reading for primatologists, anthropologists, animal behaviorists and evolutionary biologists.

This volume brings together primary data from a variety of primate species living in both natural habitats and experimental settings, and explores the variables that may play a role in primates' behavioral strategies. Taken together, these studies demonstrate that predator sensitive foraging is relevant to many primates, of various body sizes and group sizes and living in different environments. Eat or be Eaten encourages further discussion and investigation of the subject and will make fascinating reading for researchers and students in primatology, ecology, and animal behavior.

Primate Dentition provides a comparative dental anatomy of living non-human primates that brings together information from many disciplines to present the most useful and comprehensive database possible in one consolidated text. The core of the book consists of comparative morphological and metrical descriptions with analyses, reference tables, and illustrations of the permanent dentitions of 85 living primate species to establish a baseline for future investigations. The volume also discusses dental microstructure and its importance in understanding taxonomic relationships between species, data on deciduous dentitions, prenatal dental development and ontogenetic processes, and material to aid age estimation and life history studies.

Over thirty years ago, Dian Fossey established the Karisoke Research Center in Rwanda to study the behavior and ecology of mountain gorillas. Some of the offspring of the gorillas first studied by Fossey are still being observed today and the long-term observations on known individuals, from birth to death, and data on social behavior within and among the groups have led to an understanding of many aspects of gorilla social structure. Written by scientists who have worked at Karisoke over the years, this book highlights and summarizes what we have learned about the behavior, ecology, and conservation of the genus Gorilla and two other recognized subspecies and provides some comparisons with other gorilla populations elsewhere in Africa.

Studies of brain evolution have moved rapidly in recent years, building on the pioneering research of Harry J. Jerison. This book provides state-of-the-art reviews of primate (including human) brain evolution. The volume is divided into two sections, the first offers new perspectives on the developmental, physiological, dietary, and behavioral correlates of brain enlargement. However, it has long been recognized that brains do not merely enlarge globally as they evolve, but that their cortical and internal organization also changes in a process known as reorganization. Species-specific adaptations therefore have neurological substrates that depend on more than just overall brain size. The second section explores these neurological underpinnings for the senses, adaptations, and cognitive abilities that are important for primates. With a prologue by Stephen J. Gould and an epilogue by Harry J. Jerison, this is an important new reference work for all those working on primate brain evolution.

Infanticide by males is relatively common in primates, carnivores, and rodents, although it tends to be rare even in species in which it occurs. Is this behavior pathological or accidental, or does it reflect a conditional reproductive strategy for males in certain circumstances? In this book, case studies and reviews confirm the adaptive nature of infanticide by males in primates, and help to predict which species should be vulnerable to this phenomenon. Much of the book is devoted to exploring the evolutionary consequences of the threat of infanticide by males for social and reproductive behavior and physiology. Written for graduate students and researchers in animal behavior, behavioral ecology, biological anthropology, and social psychology, this book shows that social systems are shaped by ecological pressures, as well as social pressures such as infanticide risk.

Old World monkeys (Cercopithecoidea) are the most successful and diverse group of living nonhuman primates in terms of the number of species, behavioral repertoires, and ecology. Among our closest living relatives, they have much to teach us about the processes of evolution and the principles of ecology. This volume presents a broad, technical account of cercopithecoid biology including molecular, behavioral, and morphological approaches to phylogeny, population structure, allometry, fossil history, functional morphology, ecology, cognitive capabilities, social behavior, and conservation. It will be the definitive reference on this group for researchers, graduate students and advanced undergraduates in primatology, animal behavior, paleontology, morphology, systematics, and physical anthropology.

The size and composition of primate groups varies tremendously across species, within species, and within groups over time. Written by leading authorities, this book focuses on the causes and consequences of variation in the number of males per group. This variation lies at the heart of understanding adaptive variation among primate social systems. The volume also provides an extensive overview of variation in group composition across all major primate taxa using up-to-date reviews, case studies, evolutionary theory, and theoretical models. A comparative review of birds and selected other mammals is included. This text will become a favorite with all those interested in the behavioral ecology of primates.

Although the behavior and ecology of primates has been more thoroughly studied than that of any other group of mammals, there have been very few attempts to compare the communities of living primates found in different parts of the world. In Primate Communities, an international group of experts compares the composition, behavior, and ecology of primate communities in Africa, Asia, Madagascar, and South America. They examine the factors underlying the similarities and differences among these communities, including their phylogenetic history, climate, rainfall, soil type, forest composition, competition with other vertebrates, and human activities. As it brings together information about primate communities from around the world for the very first time, it will quickly become an important source book for researchers in anthropology, ecology, and conservation, and a readable and informative text for undergraduate and graduate students studying primate ecology, primate conservation, or primate behavior.

This book aims to explain the intelligence of monkeys and apes, and the huge brain expansion that marked human evolution. 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 behavioral sciences, primatology and philosophy.
