Unmatched by any other book on the market, Loons is a must-have for bird watchers, water bird enthusiasts, and nature lovers.

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.

Written as a stand-alone textbook for students and a useful reference for professionals in government and private agencies, academic institutions, and consultants, Ecology and Conservation of Fishes provides broad, comprehensive, and systematic coverage of all aquatic systems from the mountains to the oceans. The book begins with overview discussions on the ecology, evolution, and diversity of fishes. It moves on to address freshwater, estuarine, and marine ecosystems and identifies factors that affect the distribution and abundance of fishes. It then examines the adaptations of fishes as a response to constraints posed in ecosystems. The book concludes with four chapters on applied ecology to discuss the critical issues of management, conservation, biodiversity crises, and climate change. Major marine fisheries have collapsed, and there are worldwide declines in freshwater fish populations. Fishery scientists and managers must become more effective at understanding and dealing with resource issues. If not, fish species, communities, and entire ecosystems will continue to decline as habitats change and species are lost. Ecology and Conservation of Fishes has taken a historical and functional approach to explain how we got where we are, providing old and new with a better foundation as ecologists and conservationists, and most importantly, it awakens senses of purpose and need. Past management practices are reviewed, present programs considered, and the need for incorporating principles of applied ecology in future practices is emphasized.

The ultimate field guide to the birds of Ghana, an indispensable companion for any traveller to the region This spectacular new edition of Birds of Ghana is the ultimate reference to the birds of this rich and varied corner of Africa. Now fully revised and expanded, this guide is essential for researchers, birders and conservationists alike. This authoritative book covers all 773 species recorded in Ghana and neighbouring Togo, including details of all residents, migrants and known vagrants. Over 150 stunning colour plates depict every species and also comprehensively cover all the distinct plumages and subspecies likely to be encountered. Concise species accounts describe key identification features, status, range, habitat and voice with fully updated distribution maps for each species.

Males and females often differ in developmental patterns, adult morphology, ecology and behaviour, and in many mammals males are often larger. Size dimorphism results in divergent nutritional and energetic requirements or reproductive strategies by the sexes, which in turn sometimes causes them to select different forage, use different habitats, and express differing social affinities. Such divergent life-styles often lead males and females to live large parts of their lives separately. Sexual segregation is widespread in animals. Males and females may share the same habitat, but at different times, for example, or they might use different habitats entirely. Why did sexual segregation evolve and what factors contribute to it? Sexual Segregation in Vertebrates explores these questions by looking at a wide range of vertebrates and is aimed as a synthesis of our current understanding and a guide for future research.

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 science of genetics has undergone a period of very rapid and significant development in recent years, and the area of poultry genetics has been no exception. This book provides a balanced and up-to-date account of all the major areas of this subject from Mendelian to modern molecular genetics. The book begins by tracing the evolution of the domestic fowl (Gallus domesticus) from its avian ancestors. Subsequent chapters cover important aspects of poultry genetics, including cytogenetics, transmission genetics, gene mapping, sex linkage, lethal genes, genetics of feathering and plumage, and quantitative genetics. In each chapter, a concise explanation of the genetic principles is followed by a full discussion illustrated by key examples. In the latter part of the book, recent advances in gene cloning and sequencing are examined. In the area of molecular genetics, where the most rapid developments have been made, more extensive background information is given and a glossary of terms is included. The impact of these exciting new developments on our understanding of gene structure and organization, immunogenetics, and the evolution of proteins is assessed. Finally, the uses of transgenic techniques and their implications are discussed. This book provides a clear and useful survey of the genetics and evolution of the domestic fowl, which will be of interest to postgraduate students and researchers in the fields of genetics, agriculture, and veterinary medicine, as well as to poultry breeders, both commercial and non-commercial.

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.

After completing his conquest of the Persian empire, Alexander the Great maneuvered his army across the Hindu Kush and into India. During his two years there, he traveled from dry frigid mountains to humid tropical lowlands and then back across one of the most punishing deserts on the planet. He fought a series of desperate battles against strange foes mounted on war-elephants, suffering wounds that nearly killed him. And when he eventually turned homeward, he brought with him specimens of a rare, magical species, a bird that could speak with a human voice. Introduced to Europe by Alexander, parrots were quickly embraced by Western culture as exotic and astonishing, full of marvelous powers, and close to the gods. Over the centuries they would become objects of veneration or figures of folly, creatures prized for their wit-or their place on the dinner table. Ultimately, they would become emblematic of the West's interaction with the world at large. Identifying a deeply rooted obsession with these beautiful and loquacious birds, Bruce Thomas Boehrer provides the first account of parrots and their impact on the Western world. Parrot Culture: Our 2500-Year-Long Fascination with the World's Most Talkative Bird traces the unusual history of parrots from their introduction in the Graeco-Roman world as items of oriental luxury, through the great age of New World exploration, to the contemporary ecological crisis of globalism. Boehrer identifies the poignant irony in the way parrots became ubiquitous as symbols and mascots, while suffering near extinction at the hands of those who desired them. Exploring their presence and meanings in the art, literature, and history of Western civilization, Parrot Culture also celebrates the beauty, intelligence, and personality of these birds, whose fate will say as much about us and the world we have created as it will about them.

The biology of birds is diverse and frequently differs significantly from that of other vertebrates. Many birds migrate or fly at high altitudes, while egg-laying and feather production places high demands on nutrient uptake and storage. This book is the only comprehensive and up-to-date survey of avian biochemistry and molecular biology available. It emphasises the similarities and differences between birds and other vertebrates, concentrating on new developments. The first section deals with protein, lipid and carbohydrate metabolism, its hormonal control and the adaptations that occur in birds. The second covers the avian genome, gene expression, and avian immunology. Growth and embryological development are also discussed. Avian Biochemistry and Molecular Biology will be of interest to all those working on birds, especially postgraduate students and researchers.

When seen hunting over a meadow, barn owls have an ethereal grace and beauty that can be matched by no other bird. The barn owl has an almost global distribution and has lived in close proximity to humans since settlement and farming created the forest clearings needed for hunting and places in which to nest. However, in many countries, barn owl numbers are falling rapidly. This book explores the relationships between barn owls and their prey worldwide, and demonstrates how an understanding of such relationships can help in the conservation of the species. In this comprehensive account, Iain Taylor describes the biology and ecology of this species, including the factors affecting breeding success, and causes of mortality affecting the final recruitment of new birds into the population. He concludes by suggesting ways in which we can manage and conserve this beautiful bird for the future.

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.

Biological invaders represent one of the primary threats to the maintenance of global biodiversity, human health, and the success of human economic enterprises. The continuing globalization of our society ensures that the need to understand the process of biological invasion will only increase in the future. There is also a growing recognition that the study of biological invaders provides a unique insight into basic questions in ecology and evolution.
The study of exotic birds has had a particularly long history and has come to represent a fascinating intersection between the study of biological invasions, avian conservation biology, and basic principles of ecology and evolution. Avian Invasions summarizes and synthesizes this unique historical record and unravels the insights that the study of exotic birds brings to all three of these research strands. It includes chapters on the well-known contributions of exotic bird study to ecological science, and on the post-establishment evolution of introduced bird populations. The result is the most comprehensive picture yet of the invasion process.
Avian Invasions is aimed at professional avian biologists and ornithologists as well as graduate students of avian ecology, evolution and conservation. It also appeals to a more general audience of invasion ecologists.

Full-colour photographs and descriptive text for each species, along with useful and interesting information, make for easy identification. While focusing on southern Africa, the book is also applicable to the entire east coast of Africa, as well as the islands of the western Indian Ocean – Seychelles, Mauritius, Reunion, Madagascar, the Comoros and the Maldives.

Indispensable for divers, snorkelers and rock-pool enthusiasts, as well as fishermen and marine aquarists.

Woodlands offer birds an extremely wide range of habitats. In this book, the variation in bird life in woodlands, and the factors that influence bird numbers and distributions are examined. What birds are found in which habitats? What effect does forestry and woodland management have? How can we enhance bird populations by habitat management? Are bird numbers and distributions in natural and managed forests different - and if so, why? The gamut of British woodland is covered, from ancient coppice and wood-pasture in the lowlands, to recently-planted conifer forests in the uplands, and comparisons are drawn with mainland Europe and North America. The book discusses the effects of factors such as increased deer numbers, air-pollution and new wood creation on lowland farms, all of which are changing the face of our woodlands today. This book is a must for all those interested in woodlands, and the birds which live in them.

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.
