The aim of this book is to examine a variety of problems in the understanding of the evolutionary history of the marsupials. In his exposition, the author covers developmental and reproductive biology, the cranio-skeletal system (including dentition, skull, and postcranial morphology), and the ecologically related aspects of skeletal morphology. In reviewing the evidence from bones, he presents much new information on both living and fossil groups of marsupials. All groups of marsupials are treated in detail, and in the final chapter their history in space and time and their paleobiogeography are considered.

Whales and dolphins are icons for the conservation movement. They are the most conspicuous ambassadors for entire marine ecosystems and possibly even for the biosphere as a whole. Concurrent with our realisation of impending threats to their environment is a growing scientific understanding of the social and cognitive complexity of many of these species. This book brings together experts in the relevant diverse fields of cetacean research, to provide authoritative descriptions of our current knowledge of the complex behaviour and social organization of whales and dolphins. The authors consider this new information in the context of how different human cultures from around the world view cetaceans and their protection, including attitudes to whaling. They show how new information on issues such as cetacean intelligence, culture and the ability to suffer, warrants a significant shift in global perceptions of this group of animals and how these changes might be facilitated to improve conservation and welfare approaches.

The genus Macaca is the most widely distributed of non-human primates. All macaque species, except the North African Barbary macaque, are found in 20 countries in the South-East Asia region. Fossil evidence suggests that, in the Pleistocene period, the macaques were more widespread, living throughout most of Eurasia and northern Africa, but they have now disappeared between North Africa and South-East Asia. Over the comparatively short time span of 5 million years, macaques have evolved diverse forms, from long tailed arboreal types to robust terrestrial animals, and live in a variety of habitats. Studies of this group will give us important insights into the speciation process in a radiating group of non-human primates. Although macaques are probably one of the most studied cercopithecine monkeys both in the wild and in captivity, data from long-term studies and pioneering work of little-known species are only just emerging. In this book, world authorities on macaques interpret recent research and present up-to-date syntheses of many aspects of macaque ecology, evolution, behaviour and conservation. This book will prove to be the definitive synthesis of the subject for all those interested in this fascinating group of monkeys for many years to come.

From eminent biologists like Alfred Russel Wallace and Charles Darwin to famous authors such as Rudyard Kipling in his Just So Stories, many people have asked, "Why do zebras have stripes?" There are many explanations, but until now hardly any have been seriously addressed or even tested. In Zebra Stripes, Tim Caro takes readers through a decade of painstaking fieldwork examining the significance of black-and-white striping and, after systematically dismissing every hypothesis for these markings with new data, he arrives at a surprising conclusion: zebra's markings are nature's defense against biting fly annoyance. Popular explanations for stripes range from camouflage to confusion of predators, social facilitation, and even temperature regulation. It is a challenge to test these proposals on large animals living in the wild, but using a combination of careful observations, simple field experiments, comparative information, and logic, Caro is able to weigh up, scientifically, the pros and cons of each idea. Eventually driven by experiments showing that biting flies avoid landing on striped surfaces, observations that striping is most intense where biting flies are abundant, and by his knowledge of zebras' susceptibility to biting flies and vulnerability to the diseases that flies carry Caro concludes that black-and-white stripes are an adaptation to thwart biting fly attack. Not just a tale of one scientist's quest to solve a classic mystery of biology, Zebra Stripes is also a testament to the tremendous value of longitudinal research in behavioral ecology, demonstrating how observation, experiment, and comparative research can reshape our understanding of the natural world.

For the past three decades the mountain gorillas of Karisoke Research Center have been the subject of many studies focusing on their behaviour and ecology. Long-term observations on known individuals, from birth to death, and data on social behaviour within and between groups have led to an understanding of many aspects of gorilla social structure. The findings have made significant contributions to models of comparative primate behavioural ecology. Mountain gorillas have also been the focus of intense conservation efforts, which have become a model for conservation programs elsewhere. While most research has focused on mountain gorillas, data on the other two recognised subspecies have increased over the past twenty years. This book highlights and summarises some of the behavioural, ecological and conservation work on mountain gorillas, and makes comparisons with findings from other study sites. It represents the most up-to-date and diverse collection of information available on this endangered ape.

There is a growing interest in the biological implications of body size in animals. This parameter is now being used to make inferences and predictions about not only the habits and habitat of a particular species, but also as a way to understand patterns and biases in the fossil record. This valuable collection of essays presents and evaluates techniques of body-mass estimation and reviews current and potential applications of body-size estimates in paleobiology. Coverage is particularly detailed for carnivores, primates and ungulates, but information is also presented on marsupials, rodents and proboscideans. Body Size in Mammalian Paleobiology will prove useful to researchers and graduate students in paleontology, mammalogy, ecology and evolution programmes. It is designed to be both a practical handbook for researchers making and using body-size estimates, and a sourcebook of ideas for applying body size to paleontological problems and directions for future research.

This unique volume provides a comprehensive and up-to-date examination of all aspects of the biology of the Old World monkey genus, Theropithecus, which evolved alongside our human ancestors. The authors explore the fossil history and evolution of the genus, its biogeography, comparative evolutionary biology and anatomy, and the behaviour and socioecology of the living and extinct representatives of the genus. The parallels between the evolution of Theropithecus and early hominids are discussed. There are also two chapters of particular significance which describe how an innovative and exciting approach to the modelling of the causes of species extinction can be used with great success. This highly multidisciplinary approach provides a rare and insightful account of the evolutionary biology of this fascinating and once highly successful group of primates. Theropithecus will be of interest to researchers in the fields of primatology, anthropology, palaeontology, and mammalian behaviour, physiology and anatomy.

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.

Shaping Primate Evolution is an edited collection of state-of-the-art papers about how biological form is described in primate biology, and the consequences of form for function and behavior. The contributors are highly regarded internationally recognized scholars in the field of quantitative primate evolutionary morphology. Each chapter elaborates upon the analysis of the form-function-behavior triad in a unique and compelling way. This book is distinctive not only in the diversity of the topics discussed, but also in the range of levels of biological organization that are addressed from cellular morphometrics to the evolution of primate ecology. The book is dedicated to Charles E. Oxnard, whose influential pioneering work on innovative metric and analytic techniques has gone hand-in-hand with meticulous comparative functional analyses of primate anatomy. Through the marriage of theory with analytical applications, this volume will be an important reference work for all those interested in primate functional morphology.

Throughout North America, non-native wild pigs have become an ecologically and economically destructive invasive species. Though they are regarded as a popular game species by some, provide economic benefits to others, and are even engrained into societal heritage in some areas, wild pigs are responsible for an extraordinary amount of damage in both natural and anthropogenic systems throughout North America. As the density and range of wild pig habitat have substantially increased over the last several decades, the magnitude and diversity of their negative impacts are not yet fully realized or quantified. With various conflicts continually emerging, wild pig management is difficult and expensive to achieve. As a result, wild pigs represent one of the greatest wildlife management challenges North America faces in the 21st century. Invasive Wild Pigs in North America: Ecology, Impacts, and Management addresses all aspects of wild pig biology, ecology, damage, and management in a single comprehensive volume. It assimilates and organizes information on the most destructive introduced vertebrate species in the United States, establishing a foundation from which managers, researchers, policy makers, and other stakeholders can build upon into the future. The book provides comprehensive coverage of wild pig biology and ecology, techniques for management and research, and regional chapters. It is an asset to readers interested in wild pigs, the resources they impact, and how to mitigate those impacts, and establishes a vision of the future of wild pigs in North America. Features: Compiles valuable knowledge for a broad audience including wild pig managers, researchers, adversaries, and enthusiasts from across North America Addresses taxonomy, morphology, genetics, physiology, spatial ecology, population dynamics, diseases and parasites, and the naturalized niche of wild pigs Includes chapters on damage to resources, management, research methods, human dimensions and education, and policy and legislation Contains full color images and case studies of interesting and informative situations being created by wild pigs throughout North America Includes a chapter on wild pigs at the wildland-urban interface, a more recent and especially challenging issue

This complete guide to great white shark specimens preserved in the museums and aquariums of the United States catalogs 160 great white shark items in 26 institutions. The preserved material includes whole specimens as well as parts of specimens (jaws, teeth, vertebrae, etc.) Each entry details the methods of preserving or preparing the specimen (freezing, drying, taxidermying or skin-mounting, embalming, fixating followed by permanent storage in aqueous solutions of ethyl or isopropyl alcohols), and creating a model of the shark cast from a mold of the original specimen. The work also includes a general introduction describing the biology, ethology and ecology of the great white shark and more detailed accounts of the various preservation methods.

This insightful examination of the history and extinction of one of Australia's most enduring folkloric beasts--the thylacine, (or Tasmanian tiger)-- challenges conventional theories. It argues that rural politicians, ineffective political action by scientists, and a deeper intellectual prejudice about the inferiority of marsupials actually resulted in the extinction of this once proud species.

Chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) are the only two species of the genus Pan, and are humans' nearest relatives. This book is an extensive review of the most recent observations from field studies on the diversity of Pan social behavior, with contributions from many of the world's leading experts. A wide range of social behavior is discussed including tool use, hunting, reproductive strategies, conflict management, demographic variables and ecological constraints. In addition to interspecies behavioral diversity, this text describes exciting new research into variations between different populations of the same species.

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 observing 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.

Comparative studies have become both more frequent and more important as a means for understanding the biology, behavior, and evolution of mammals. Primates have complex social relationships and diverse ecologies, and represent a large species radiation. This book draws together a wide range of experts from diverse fields, such as reproductive biology and foraging energetics, to place recent field research into a synthetic perspective. The chapters tackle controversial issues in primate biology and behavior, including the role of brain expansion and infanticide in the evolution of primate behavioral strategies. The volume also presents an overview of comparative methodologies as applied to recent primate research.

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.

African mole-rats are a unique taxon of subterranean rodents that range in sociality from solitary-dwelling species 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 behavioral and reproductive division of labor. 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, Nigel Bennett and Chris Faulkes provide a synthesis of the current knowledge of bathyergid systematics, ecology, reproductive biology, behavior, and genetics. They explore the role of these factors in the evolution of sociality in the Bathyergidae in the context of both vertebrates and invertebrates. This volume will be an important new resource for anyone interested in the evolution of sociality, specifically in mole-rats.

1 Introduction The esophagus is a relatively simple though vital organ. It consists of a two-layered muscular tube whose lumen is lined by squamous strati?ed epithelium. Beyond its role of propelling food from the pharynx to the stomach by a propulsive contraction wave representing the esophageal phase of deglutition (Conklin and Christensen 1994; Jean 2001), it is more and more recognized as a sensory organ from which a variety of respiratory and cardiovascular re?exes can be triggered, thus coop- ating with the larynx in protecting the lower airways from aspiration (Barthelemy et al. 1996; Lang et al. 2002; Lang et al. 2001; Loomis et al. 1997; Medda et al. 2003). In ruminants, there is additional antiperistalsis for regurgitation. During emesis, the esophagus is a merely passive conduit except for some antiperistalsis in its upper part. In the interval between swallows, both oral and aboral ends of the esophagus are tonically closed by the upper and lower esophageal sphincters, UES and LES respectively, while the tubular esophagus is ?accid and partly ?lled with air. Despite this apparent simplicity, neuronal control of esophageal functions is quite complex.

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.

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.
