For a wide spectrum of scientists from biomedical and dental researchers to primatologists and physical anthropologists, Emet Schneiderman offers the most accurate and up-to-date presentation of the normal growth of the lower facial skeleton in a primate species. His study is based on a sample of thirty-five captive rhesus monkeys, whose facial growth was traced over a ten-year period spanning from infancy to adulthood. The author identifies the relative contribution of various sites of growth, quantifies the relative roles of different types of development--such as appositional and condylar--and sheds light on several long-standing controversies as to how the primate face grows. Unlike many of the traditional cephalometric measurements, the ones included in this work were chosen to reflect the positional, dimensional, and localized remodeling changes that occur during ontogeny. Using a new statistical approach designed for longitudinal data, Schneiderman avoids the misleading information that has often resulted from older, cross-sectional statistical methods. This book serves as a foundation for future experimental and normal studies in the rhesus monkey and, from a methodological standpoint, as a general model for future longitudinal growth studies.

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.

This is the only field guide to provide comprehensive coverage of the mammals of Central America and Southeast Mexico. This edition features 21 new species accounts, including nine for bats. Four new full-color maps show parks and protected areas, biomes, elevations, and habitat loss. From Funnel-eared Bats and Spider Monkeys to Climbing Rats and Pocket Mice, Anteaters and Sloths to Sperm Whales and Ocean Dolphins, the guide fully describes every known regional species. Over 150 range maps have been updated along with present conservation status and habitat information. The new book features descriptions and measurements, where and when each species might be found, what type of nests or dens it uses, feeding habits, and reproductive cycles. Highlights include the 49 (previously 48) vibrant full-color animal illustrations, most painted directly from live subjects. Tracks and feet appear on facing-pages. A glossary and updated bibliography round out the usefulness of this indispensable guide.

Many mammals, such as otters, live in close association with rivers and streams, feeding in them, or using them as a place of safety or means of escape from predators. The distinct adaptations that riparian mammals have evolved in order to live in these environments also handicap them for living elsewhere. These animals are therefore threatened by alterations to their environment. In recent years, our rivers have become highly polluted, and have been subject to bankside modifications for agriculture and forestry, enhanced or decreased water flow, and recreation. As a result, they have become less and less suitable for these highly specialized animals. This book looks at the habitat utilization, adaptation, feeding ecology, and conservation status of a range of riparian mammals. It gives insights into the problems facing these fascinating animals, and how they might be overcome.

Social learning commonly refers to the social transfer of information and skill among individuals. It encompasses a wide range of behaviours that include where and how to obtain food, how to interact with members of one's own social group, and to identify and respond appropriately to predators. The behaviour of experienced individuals provides natural sources of information, by which inexperienced individuals may learn about the opportunities and hazards of their environment, and develop and modify their own behaviour as a result. A wide diversity of species is discussed in this book, some of which have never been discussed in this context before, and particular reference is made to their natural life strategies. Social learning in humans is also considered by comparison with other mammals, especially in their technological and craft traditions. Moreover, a discussion is included of the social learning abilities of prehistoric hominids.

Primate and Human Evolution provides a synthesis of the evolution and adaptive significance of human anatomical, physiological and behavioral traits. Using paleontology and modern human variation and biology, it compares hominid traits to those of other catarrhine primates both living and extinct, presenting a new hominization model that does not depend solely on global climate change, but on predictable trends observed in catarrhines. Dealing with the origins of hominid tool use and tool manufacture, it compares tool behavior in other animals and incorporates information from the earliest archaeological record. Examining the use of non-human primates and other mammals in modeling the origins of early human social behavior, Susan Cachel argues that human intelligence does not arise from complex social interactions, but from attentiveness to the natural world. This book will be a rich source of inspiration for all those interested in the evolution of all primates, including ourselves.

Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

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.

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.

African mole-rats are a unique taxon of subterranean rodents that range in sociality from solitary-dwelling species through to two 'eusocial' species, the Damaraland Mole-Rat and the Naked Mole-Rat. The Naked Mole-Rat is arguably the closest that a mammal comes to behaving like social insects such as bees and termites, with large colonies and a behavioural and reproductive division of labour. As a family, the Bathyergidae represent a model system with which to study the evolution and maintenance of highly social cooperative breeding strategies. In this book, first published in 2000, Nigel Bennett and Chris Faulkes provide a synthesis of the knowledge of bathyergid systematics, ecology, reproductive biology, behaviour and genetics. With this, they explore the role of these factors in the evolution of sociality in the Bathyergidae in the context of both vertebrates and invertebrates. This will be an important new resource for anyone interested in the evolution of sociality, and in mole-rats in particular.

However well the anatomy of the gastro-intestinal tracts of a wide range of mammals is 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 of the 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 utilisation. Macroscopic and ultrastructural studies of the gastro-intestinal 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 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.

Mammals are the dominant large animals of today, occurring in virtually every environment. This book is an account of the remarkable 320 million year long fossil record that documents their origin, their long spell as no more than small, nocturnal creatures, and their explosive radiation since the extinction of the dinosaurs 65 million years ago. Tom Kemp also unveils the exciting molecular evidence, which, coupled with important new fossils, is presently challenging current thinking on the interrelationships and historical biogeography of mammals. The Origin and Evolution of Mammals will be of interest to advanced undergraduate and graduate students as well as researchers in vertebrate palaeontology, biogeography, mammalian systematics and molecular taxonomy. It will also be welcomed by vertebrate fossil enthusiasts and evolutionary biologists of all levels with an interest in macroevolutionary problems.

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.

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.

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.

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.

With their tonsured heads, white faces, and striking cowls, the monkeys might vaguely resemble the Capuchin monks for whom they were named. How they act is something else entirely. They climb onto each other's shoulders four deep to frighten enemies. They test friendship by sticking their fingers up one another's noses. They often nurse--but sometimes kill--each other's offspring. They use sex as a means of communicating. And they negotiate a remarkably intricate network of alliances, simian politics, and social intrigue. Not monkish, perhaps, but as we see in this downright ethnographic account of the capuchins of Lomas Barbudal, their world is as complex, ritualistic, and structured as any society.

"Manipulative Monkeys" takes us into a Costa Rican forest teeming with simian drama, where since 1990 primatologists Susan Perry and Joseph H. Manson have followed the lives of four generations of capuchins. What the authors describe is behavior as entertaining--and occasionally as alarming--as it is recognizable: the competition and cooperation, the jockeying for position and status, the peaceful years under an alpha male devolving into bloody chaos, and the complex traditions passed from one generation to the next. Interspersed with their observations of the monkeys' lives are the authors' colorful tales of the challenges of tropical fieldwork--a mixture so rich that by the book's end we know what it is to be a wild capuchin monkey or a field primatologist. And we are left with a clear sense of the importance of these endangered monkeys for understanding human behavioral evolution.

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.

"Part review, part testament to extraordinary dedication, and part call to get involved, "Cetacean Societies" highlights the achievements of behavioral ecologists inspired by the challenges of cetaceans and committed to the exploration of a new world."--from the preface by Richard Wrangham
Long-lived, slow to reproduce, and often hidden beneath the water's surface, whales and dolphins (cetaceans) have remained elusive subjects for scientific study even though they have fascinated humans for centuries. Until recently, much of what we knew about cetaceans came from commercial sources such as whalers and trainers for dolphin acts. Innovative research methods and persistent efforts, however, have begun to penetrate the depths to reveal tantalizing glimpses of the lives of these mammals in their natural habitats.
"Cetacean Societies" presents the first comprehensive synthesis and review of these new studies. Groups of chapters focus on the history of cetacean behavioral research and methodology; state-of-the-art reviews of information on four of the most-studied species: bottlenose dolphins, killer whales, sperm whales, and humpback whales; and summaries of major topics, including group living, male and female reproductive strategies, communication, and conservation drawn from comparative research on a wide range of species.
Written by some of the world's leading cetacean scientists, this landmark volume will benefit not just students of cetology but also researchers in other areas of behavioral and conservation ecology as well as anyone with a serious interest in the world of whales and dolphins.
Contributors are Robin Baird, Phillip Clapham, Jenny Christal, Richard Connor, Janet Mann, Andrew Read, Randall Reeves, Amy Samuels, Peter Tyack, Linda Weilgart, Hal Whitehead, Randall S. Wells, and Richard Wrangham.

This is a general introduction to the biology of bats, suitable as a text for courses in the subject, and as a reliable reference to all aspects of the subject for a broad range of biologists. The book presents a balanced coverage of the physiologiy, anatomy, behavior, ecology, and phylogeny of bats. Bats comprise about 25% of all mammalian species, and because of their diversity and their complex behaviors, they are among the most intesively studied groups in the Mammalia. Gerhard Neuweiler is an internationally recognized authority on bats, and one of the leading workers on the physiology of echolocation.
