The illegal trade in live apes, ape meat and body parts occurs across all ape range states and poses a significant and growing threat to the long-term survival of wild ape populations worldwide. What was once a purely subsistence and cultural activity, now encompasses a global multi-million-dollar trade run by sophisticated trans-boundary criminal networks. The challenge lies in teasing apart the complex and interrelated factors that drive the ape trade, while implementing strategies that do not exacerbate inequality. This volume of State of the Apes brings together original research and analysis with topical case studies and emerging best practices, to further the ape conservation agenda around killing, capture and trade. This title is also available as Open Access via Cambridge Core.

The bonobo, along with the chimpanzee, is one of our two closest living relatives. Their relatively narrow geographic range (south of the Congo River in the Democratic Republic of Congo) combined with the history of political instability in the region, has made their scientific study extremely difficult. In contrast, there are dozens of wild and captive sites where research has been conducted for decades with chimpanzees. Because data sets on bonobos have been so hard to obtain and so few large-scale studies have been published, the majority of researchers have treated chimpanzee data as being representative of both species. However, this misconception is now rapidly changing. With relative stability in the DRC for over a decade and a growing community of bonobos living in zoos and sanctuaries internationally, there has been an explosion of scientific interest in the bonobo with dozens of high impact publications focusing on this fascinating species. This research has revealed exactly how unique bonobos are in their brains and behavior, and reminds us why it is so important that we redouble our efforts to protect the few remaining wild populations of this iconic and highly endangered great ape species.

As our closest primate relatives, chimpanzees offer tantalizing clues about the behavior of early human ancestors. This book provides a rich and detailed portrait of chimpanzee social life in the wild, synthesizing hundreds of thousands of hours of research at seven long-term field sites. Why are the social lives of males and females so different? Why do groups of males sometimes seek out and kill neighboring individuals? Do chimpanzees cooperate when they hunt monkeys? Is their vocal behaviour like human speech? Are there different chimpanzee 'cultures'? Addressing these questions and more, Adam Arcadi presents a fascinating introduction to the chimpanzee social universe and the challenges we face in trying to save this species from extinction. With extensive notes organized by field site and an appendix describing field methods, this book is indispensable for students, researchers, and anyone else interested in the remarkable and complex world of these intelligent apes.

Ever since Jane Goodall unlocked the mysteries of wild chimpanzees, and Dian Fossey lived among Mountain gorillas, the world has been captivated by primates and the people who study them. Here at last, is the riveting story of Birute Galdikas, a pioneering primatologist who has spent much of herlive studying orangutans.

In 1971, twenty-five-year-old Galdikas began living in the remote jungles of Indonesian Borneo, where she encountered menacing poachers, blood-sucking leeches and swarms of carnivorous insects. Determined to penetrate the world of the elusive "red ape" in the name of science and conservation, Galdikas embarked on a quest of more than twenty years to become the foremost chronicler of orangutan life. Her first task was to form a bond of trust with the animals, but her initial forays into their world were thwarted by skeptical and territorial orangutans like handsome Cara, who hurled dead branches at Galdikas from the tree canopy above. Eventually Galdikas became a surrogate member of the community, triumphantly claimed as "mother" by little Sugito, who clung to her fiercely, night and day, for months. Reflections of Eden is an exotic adventure, a history of vital scientific research, and the memoir of a remarkable woman.

This book is a collection of fascinating contributions from research experts around the world and their studies on monkeys, their brains, behaviours, endocrinology, diseases that pose potential threats to our species and the evolution of hormonal genes. If "humans are like onions -- made of layers", as said by the character in the movie Shrek, monkeys are perhaps made of the same layers, except for the outermost. Thus, we share most of our genetics, physiology and pathology with them, in addition to our behaviour and social conduct. These great similarities, particularly in metabolic aspects, are thoroughly documented by the authors that close the book which describes the baboon as just an experimental animal model used to discover the genetic and hormonal alterations behind the appearance of those chronic diseases that have become a pandemic. The authors dealing with the brain development subject make the point that, given the position that non-human primates (NHP) occupy within the evolutionary tree, and as the closest phylogenetic species to humans, the rhesus monkeys constitute an ideal animal model for the study of fundamental neural mechanisms occurring throughout the developmental and maturation phases of life; from the neonatal to senile stages.

This book focuses on the biology, behaviours and disorders of monkeys. Topics discussed include the use of non-human primates in biogerontology; cognitive correlates of communication in primates; effects of the adverse rearing experience on the organisation of the brain and behaviour among non-human primates; parent-infant relationships in Marmosets; planning abilities of monkeys; neuropeptides in the monkey brainstem and developmental neuronal toxicity and the Rhesus monkey.

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.

Furry and wide-eyed, lorises and pottos are small, nocturnal primates inhabiting African, Asian and Southeast Asian tropical and subtropical forests. Their likeable appearance, combined with their unusual adaptations - from a marked reduction of the tail to their mostly slow, deliberate locomotion, powerful grasping and, in some species, a venomous bite - has led to a significant rise in research interest in the family Lorisidae over the last decade. Furthermore, lorises in particular have featured frequently in international media largely due to illegal trade, for example as pets. This is the first volume to present a full picture of the breadth of research being undertaken on lorisids to aid future studies as well as conservation efforts. Focusing on five key topics: evolutionary biology, ecomorphology, behavioural ecology, captive management and conservation, this book is a vital read for graduate students and researchers in primatology, biological anthropology, evolutionary biology, animal behaviour and conservation.

In Decolonizing Extinction Juno Salazar Parrenas ethnographically traces the ways in which colonialism, decolonization, and indigeneity shape relations that form more-than-human worlds at orangutan rehabilitation centers on Borneo. Parrenas tells the interweaving stories of wildlife workers and the centers' endangered animals while demonstrating the inseparability of risk and futurity from orangutan care. Drawing on anthropology, primatology, Southeast Asian history, gender studies, queer theory, and science and technology studies, Parrenas suggests that examining workers' care for these semi-wild apes can serve as a basis for cultivating mutual but unequal vulnerability in an era of annihilation. Only by considering rehabilitation from perspectives thus far ignored, Parrenas contends, could conservation biology turn away from ultimately violent investments in population growth and embrace a feminist sense of welfare, even if it means experiencing loss and pain.

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

These compelling stories and photographs take us to places like Bwindi Impenetrable National Park in Uganda, Ivindo National Park in Gabon, and the Tai National Park in Cote d'Ivoire for an intimate and revealing look at the lives of African wild apes - and at the lives of the humans who study them. In tales of adventure, research, and conservation, veteran field researchers and conservationists describe exciting discoveries made over the past few decades about chimpanzees, bonobos, and gorillas. This book features vivid descriptions of interactions among these highly intelligent creatures as they hunt, socialize, and play. More difficult themes emerge as well, including the threats apes face from poaching, disease, and deforestation. In stories that are often moving and highly personal, this book takes measure of how special the great apes are and discusses positive conservation efforts, including ecotourism, that can help bring these magnificent animals back from the brink of extinction.

Primatology draws on theory and methods from diverse fields, including anatomy, anthropology, biology, ecology, medicine, psychology, veterinary sciences and zoology. The more than 500 species of primate range from tiny mouse lemurs to huge gorillas, and primatologists collect data in a variety of environments including in the field, research facilities, museums, sanctuaries, zoos, and from the literature. The variability in research interests, study animals and research sites means that there are no standard protocols for how to study primates. Nevertheless, asking good questions and designing appropriate studies to answer them are vital to produce high quality science. This accessible guide for graduate students and post-doctoral researchers explains how to develop a research question, formulate testable hypotheses and predictions, design and conduct a project and report the results. The focus is on research integrity and ethics throughout, and the book provides practical advice on overcoming common difficulties researchers face.

Key features: Offers chapters by renowned experts which are comprised of three subunits: a theoretical discussion of the content area, a description of the methods employed to address the content area, and finally, and most importantly, a discussion of the ways that relevant aspects of the content area can be easily employed/adapted to enhance the behavioral management of NHPs Provides case studies that highlight the areas of expertise of the authors and emphasize 'success stories' that can be used to develop behavioral management strategies and build behavioral management programs Presents 'Genera-specific' chapters which focus on behavioral management strategies that, typically, are successfully employed with particular taxa of NHPs Includes a novel, pioneering 'Product/services' section that provides the producers of important technologies, equipment, and services with an opportunity to highlight the ways in which their products enhance the ability of their clients to manage the behavior of NHPs Illustrated with full color images and drawings throughout. The Handbook of Primate Behavioral Management (HPBM) fills a void in the scientific literature, providing those who work with nonhuman primates (NHPs) with a centralized reference for many issues related to the care and behavioral management of captive nonhuman primates. While there are numerous publications scattered throughout the literature that deal with the behavioral management of NHPs, this comprehensive handbook is the first single-source reference to summarize and synthesize this information. The HPBM is organized into six complementary parts starting with an introductory section. The book then provides in-depth coverage of content issues, applications and implementation, genera-specific chapters, technology-related questions involved in the behavioral management of NHPs, and a concluding section. Primate behavioral management is a topic that has recently generated a considerable number of primary publications in the scientific literature, mostly with an applied focus. Similarly, there are many primary publications currently available that address more basic issues related to the understanding of primate behavior. One of the principal goals of the HPBM is to highlight and synthesize basic science advances that can be adapted and applied to enhance the behavioral management of captive NHPs.

This book takes a new approach to understanding primate conservation research, adding a personal perspective to allow readers to learn what motivates those doing conservation work. When entering the field over a decade ago, many young primatologists were driven by evolutionary questions centered in behavioural ecology. However, given the current environment of cascading extinctions and increasing threats to primates we now need to ensure that primates remain in viable populations in the wild before we can simply engage in research in the context of pure behavioural ecology. This has changed the primary research aims of many primatologists and shifted our focus to conservation priorities, such as understanding the impacts of human activity, habitat conversion or climate change on primates. This book presents personal narratives alongside empirical research results and discussions of strategies used to stem the tide of extinction. It is a must-have for anyone interested in conservation research.

Living in the remote forests of western central Africa, the mandrill (Mandrillus sphinx) is notoriously elusive and has evaded scientific scrutiny for decades. Yet, it is the largest and most sexually dimorphic of all the Old World monkeys, and perhaps the most colourful of all the mammals. Synthesising the results of more than twenty-five years of research, this is the first extensive treatment of the mandrill's reproductive and behavioural biology. Dixson explores in detail the role that sexual selection has played in shaping the mandrill's evolution, covering mechanisms of mate choice, intra-sexual competition, sperm competition and cryptic female choice. Bringing to life, through detailed descriptions and rich illustrations, the mandrill's communicatory biology and the functions of its brightly coloured adornments, this book sheds new light on the evolutionary biology of this fascinating primate.

In this book, the authors present topical research in the study of the classification, evolution and behaviour of primates. Topics discussed in this compilation include the analysis of the attachments, relative weights, and innervation of the lower limb muscles of various apes and modern humans; Alzheimer pathology in non-human primates and its pathophysiological implications; the evolutionary transformations and adaptations related to the different locomotor modes developed by hylobatids, orang-utans, gorillas, chimpanzees and modern humans; neurobiological correlates of behavioural and cognitive performance in non-human primates; and assessing the cognitive capacities of various non-human primate species.

Primates use four major modes of communication (i.e., visual, olfactory, tactile and vocal), and the ways they communicate depend on restrictions imposed by their habits and habitats. This book discusses past, current and potential future research in the wild and captivity, addressing some of the key questions in primate bioacoustics, identifying gaps in our knowledge, and also describing basic methods and equipment used in the study of primate bioacoustics. Also investigated are the changes of circadian rhythm of the hypothalamic-pituitary-adrenal (HPA) axis activity in non-human primates under stress and during ageing. This book presents data collected from gibbons in a sanctuary, a rehabilitation centre and also the wild highlighting the development of social skills and cognitive abilities. In addition, one of the dominant research areas in behavioural primatology pertains to assessments of the cognitive capacities of various non-human primate species. This book outlines studies that compare different methodologies and how those methodologies might contribute to differential learning and cognitive performance. Other chapters in this book examine the cognitive differences between humans and apes, review a powerful experimental methodology to determine the most likely acquisition modes responsible for primate "cultural" patterns, estimate home range use, activity patterns, and diet in woolly monkeys, and discuss the researchers role in preventing disease transmission between humans and apes.

In more ways than we may sometimes care to acknowledge, the human being is just another primate--it is certainly only very rarely that researchers into cognition, emotion, personality, and behavior in our species and in other primates come together to compare notes and share insights. This book, one of the few comprehensive attempts at integrating behavioral research into human and nonhuman primates, does precisely that--and in doing so, offers a clear, in-depth look at the mutually enlightening work being done in psychology and primatology.

Relying on theories of behavior derived from psychology rather than ecology or biological anthropology, the authors, internationally known experts in primatology and psychology, focus primarily on social processes in areas including aggression, conflict resolution, sexuality, attachment, parenting, social development and affiliation, cognitive development, social cognition, personality, emotions, vocal and nonvocal communication, cognitive neuroscience, and psychopathology. They show nonhuman primates to be far more complex, cognitively and emotionally, than was once supposed, with provocative implications for our understanding of supposedly unique human characteristics. Arguing that both human and nonhuman primates are distinctive for their wide range of context-sensitive behaviors, their work makes a powerful case for the future integration of human and primate behavioral research.

The first and still the only book focused exclusively on juvenile primates, this collection presents original research covering all the major divisions of primates, from prosimians to humans. Contributors explore the evolutionary history of the juvenile stage in primates; differences in behavior between juvenile males and females; how juvenile behaviors act both to prepare juveniles for adulthood and to help them survive the juvenile stage; how juveniles learn about and participate in social conflict and dominance relationships; and the similarities and differences between development of juvenile human and nonhuman primates. This edition includes a substantial new foreword and bibliography prepared by the editors.
