Of the forty mammal species known to have vanished in the world in the last 200 years, almost half have been Australian. Our continent has the worst record of mammal extinctions, with over 65 mammal species having vanished in the last 50 000 years. It began with the great wave of megafauna extinctions in the last ice-age, and continues today, with many mammal species vulnerable to extinction. The question of why mammals became extinct, and why so many became extinct in Australia has been debated by experts for over a century and a half and we are no closer to agreement on the causes. This book introduces readers to the great mammal extinction debate. Chris Johnson takes us on a detective-like tour of these extinctions, uncovering how, why and when they occurred.

Daphne Sheldrick's best-selling love story of romance, life and elephants, An African Love Story: Love, Life and Elephants is an incredible story from Africa's greatest living conservationist. A typical day for Daphne involves rescuing baby elephants from poachers; finding homes for orphan elephants, all the while campaigning the ever-present threat of poaching for the ivory trade. An African Love Story is the incredible memoir of her life. It tells two stories - one is the extraordinary love story which blossomed when Daphne fell head over heels with Tsavo Game Park and its famous warden, David Sheldrick. The second is the love story of how Daphne and David, who devoted their lives to saving elephant orphans, at first losing every infant under the age of two until Daphne at last managed to devise the first-ever milk formula which would keep them alive. 'Compulsively readable', Mail on Sunday 'An enchanting memoir', Telegraph Daphne Sheldrick has spent her entire life in Kenya. For over 25 years, she and her husband, David, the famous founder of the the giant Tsavo National Park, raised and rehabilitated back into the wild orphans of misfortune from many different wild species. These included elephants, rhinos, buffaloes, zebra, eland, kudu, impala, warthogs and many other smaller animals. In 2006 she was made Dame Commander of the British Empire by the Queen.
The last 20 years have seen many exciting discoveries in the study of marsupials, leading to significant developments in our understanding of this unique group of mammals. The impact of these developments have been such that marsupials are coming to be seen as model organisms in studies of life history evolution, ageing and senescence, sex determination and the development and regeneration of the nervous system. This volume provides a synthesis of current knowledge, bringing together information scattered throughout the primary literature. Coverage includes evolutionary history and management strategies as well as all aspects of basic biology. A complete listing of currently known species and a comprehensive list of references make this a unique repository of information on this fascinating group of animals.
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.
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.
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.
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.
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 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.
The family Rhinocerotidae has a long and amazing history in North America. From their first appearance about forty million years ago, they diversified into an incredible array of taxa, with a variety of ecologies that do not resemble any of the five living species. They ranged from delicate long-legged dog-sized forms, to huge hippo-like forms that apparently lived in rivers and lakes. This book includes a systematic review of the entire North American Rhinocerotidae, with complete descriptions, measurements, and figures of every bone in every species - the first such review in over a century. More importantly, it discusses the biogeographic patterns of rhinos, their evolutionary patterns and paleoecology, and what rhinos tell us about the evolution of North American landscapes and faunas over 35 million years. It is a complete and authoritative volume that will be a reference of interest to a variety of scientists for years to come.
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.
Mammalian hair has always had a use in human society: as fur for clothing, in the production of cloth, or in the production of brushes. Scientists, too, make use of mammalian hair as a diagnostic tool in areas such as animal ecology, wildlife biology, and nature management. The identification of hairs found in the field, in the intestine or feces of carnivores, or in the pellets of birds of prey, can yield valuable information on the distribution of mammals and the diet of their predators. With photographs and keys, this atlas aids correct identification by providing data on the color, form, and length of hair and the structure of the cuticula, medulla, and cross-sections.
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.

The effects of the bone morphogenetic proteins (BMPs) family on bone formation are well documented, but the transforming growth factor (TGF)-beta ( ) isoforms are much less studied. The product of 20 years of study, Induction of Bone Formation in Primates: The Transforming Growth Factor- 3 sums up editor Ugo Ripamonti's research into the osteogenic activity of the three mammalian TGF- isoforms, particularly in primates. It explores how the mammalian TGF- isoforms have the potential to shed light on the apparent redundancy of bone induction signaling. The book unearths the profound and important bone inductive activity of the TGF- 3 isoform. It includes accounts of extensive research in non-human primates from craniofacial tissue regeneration, heterotopic tissue induction, and chapters on periodontal tissue regeneration and synergistic induction of bone formation. It also discusses the future clinical role of the TGF- isoform, including in human studies. This book contributes to the fascinating history of BMP and TGF- research at the intersection of molecular biology, tissue induction, bone regeneration, and craniofacial surgery. It provides a revolutionary awakening to new possibilities in skeletal reconstruction, tissue engineering, and molecular and cellular biology.
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.
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.
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.
Once famous for the beauty of its white beaches, reef-ringed islands, and lush forests, today the Philippines is known as an example of the deep costs of ecological decline. In less than a generation, large and small users alike felled the forests, shattered the coral reefs, and over-fished the oceans. The rapid harvest of the once-abundant resources has brought environmental changes: droughts, deadly flash floods, and the collapse of vital fisheries. The consequences have reverberated throughout the country. As the rural economy weakened, millions migrated to the cities, overwhelming the infrastructure and deepening the problems of urban health. Pioneering efforts have been launched to curtail the environmental damage and manage the resources that remain. Trained as a botanist and plant ecologist, writer Barbara Goldoftas traveled extensively throughout the archipelago to document the loss of the natural resources, the dramatic human costs, and efforts to reverse the decline. Along the forest frontier, she met villagers whose fields had been washed away by mudslides and church workers risking their lives to defend the dwindling forests. In coastal villages, she spoke with fishermen who, having watched their catches diminish with the dying reefs, enforced the boundaries of no-take zones. In towns and villages alike, she interviewed local politicians and leaders of non-governmental organizations working to combine conservation and development and keep their communities intact. Written about a country often described as an environmental worst-case scenario, The Green Tiger offers an unusually close look at the consequences of ecological decline and determined efforts to reverse them. Itargues that, rather than destroying a natural resource base, development should integrate conservation and economic growth. It gives a realistic, but optimistic vision of the long process of "nation-building" that is the backdrop of environmental work in a developing country and a new democracy. |
