This second edition offers a comprehensive overview of the physiological functions of vertebrate kidneys from a comparative viewpoint, with particular emphasis on nonmammalian vertebrates. The topics covered include renal structure; glomerular ultrafiltration; tubular transport of inorganic ions, organic substances, and fluid; and urine dilution and concentration. Mammalian renal function is only considered for purposes of comparison with nonmammalian renal function and as a frame of reference for some of the discussions. The major findings on nonmammalian renal function and the important unanswered questions raised by those findings are described in detail. As such, the book provides comprehensive information on comparative renal function for biological scientists and advanced students of biology with some knowledge of physiology and a desire to know more about renal function in vertebrates, and for mammalian renal physiologists who wish to obtain a broader view of renal function.

Dramatic changes in the environment, including habitat degradation and climate change, have focused attention on how individuals and populations respond to a shifting biotic and abiotic landscape. A critical step toward meeting this goal is a clear understanding of the capacity of individuals to defend themselves against threats. Changes in water quality and temperature have direct and indirect effects on fishes. Defensive responses can occur at many levels, from cellular to behavioral actions. The authors in this volume have attempted to provide a general view of the current state of knowledge of fish defenses with respect to pathogens, parasites, and predators, and to point out gaps where further study is needed.

This wonderful book describes the fascinating lives of the two most ubiquitous shorebirds in the world. Between them the Common Sandpiper (Actitis hypoleucos) and Spotted Sandpiper (Actitis macularia) make use of a large part of the world's terrestrial habitat and they exhibit many of the exciting features of shorebirds. As the birds arrive on the breeding ground, their displays are spectacular and their sounds are an exciting announcement of springtime. Unusually, the Spotted Sandpiper appears to be the only bird where the female is the territory holder, laying successive clutches of eggs for different males to care for, while the male of the Common Sandpiper holds the territory, has one mate, and shares most duties. They stay on the breeding grounds only as long as is essential to reproduce before making a migration southwards to a broad range of non-breeding homes in Central and South America, Africa, India, and eastwards to Australia with vagrants reaching as far as Tristan da Cunha and New Zealand. The Common Sandpiper has also been recorded breeding in East Africa and wintering in Scotland so their flexibility is amazing. The author has spent over 40 years studying the lives of these fantastic birds and provides a wealth of information including their breeding behaviour, migrations, distribution, food sources, habitats and their history from the present back to 36 million years ago. This beautiful book will hopefully stimulate others to watch these worldwide birds more appreciatively and add to our knowledge.

The Roberts Bird Guide (2nd Edition) has gone to great trouble to concentrate on, and illustrate, difficult-to-identify species and family groups such as raptors, warblers, cisticolas and waders. Special attention has been given to make sure there is far greater coverage of male-female differences and there are also many more juvenile illustrations. Unlike all previously published southern African bird guides, this new edition will be scattered with informative photographs that are incorporated in the text pages and each plate illustration is augmented with an introduction. Apart from the approximately 240 plate spreads, the guide also has 12 photographic and illustrated double spreads that show head enlargements and other details. Plates are annotated far more definitively than other guides – highlighting key identification features, especially for difficult-to-identify species.

This text comprises of two volumes discussing the regulation of carbohydrate metabolism.

Although scholars have long recognized the mythic status of bears in Indigenous North American societies of the past, this is the first volume to synthesize the vast amount of archaeological and historical research on the topic. Bears charts the special relationship between the American black bear and humans in eastern Native American cultures across thousands of years. These essays draw on zooarchaeological, ethnohistorical, and ethnographic evidence from nearly 300 archaeological sites from Quebec to the Gulf of Mexico. Contributors explore the ways bears have been treated as something akin to another kind of human-in the words of anthropologist Irving Hallowell, "other than human persons"-in Algonquian, Cherokee, Iroquois, Meskwaki, Creek, and many other Native cultures. Case studies focus on bear imagery in Native art and artifacts; the religious and economic significance of bears and bear products such as meat, fat, oil, and pelts; bears in Native worldviews, kinship systems, and cosmologies; and the use of bears as commodities in transatlantic trade. The case studies in Bears demonstrate that bears were not only a source of food, but were also religious, economic, and political icons within Indigenous cultures. This volume convincingly portrays the black bear as one of the most socially significant species in Native eastern North America. A volume in the Florida Museum of Natural History: Ripley P.

The Cardiovascular System: Phenotypic and Physiological Responses, Volume 37, part of a two-volume set, provides comprehensive coverage of the current state of knowledge in this very active and growing field of research, also highlighting the tremendous diversity in cardiovascular morphology and function among the various fish taxa and the anatomical and physiological plasticity shown by this system when faced with various abiotic and biotic challenges. Specific chapters in this updated book include Research Technologies/Methodology for Studying Fish Cardiovascular Function, Cardiovascular Development in Embryonic and Larval Fishes, Cardiovascular Responses to Limiting Oxygen Levels, and Temperature and the Cardiovascular System. The book's chapters integrate molecular and cellular data with the growing body of knowledge on heart and in vivo cardiovascular function, and as a result, provide insights into some of the most interesting, and important, questions that still need to be answered in this field.

This is a lightweight and portable guide, partly adapted from the popular and highly acclaimed A Field Guide to the Reptiles of East Africa by the same authors. Covering the most prominent 150 reptiles and 80 amphibians found in the region (Kenya, Tanzania, Uganda, Rwanda and Burundi), with concise text, photograph and map for each, this is a convenient and attractive pocket guide for a diverse and often conspicuous and attractive group of animals.

The great white shark, Carcharodon carcharias, is a marquee predator made famous by movie and myth. This text brings together the real evidence of both ecology and behaviour of these animals. This international team of separates fact from fiction and establishes a baseline from which additional research of great white sharks and sharks in general might proceed. The chapters are divided into sections on the geographic distribution, evolutionary history, behaviour with particular emphasis on the predatory relationship to seals and sea lions, movements and abundance of the species, and its interactions with man. Many of the scientific contributions resulted from the 1993 symposium in Bodega Bay, California, that attracted more than 80 specialists from around the world.

Everyone's heard of the Great Whites. But most people know little of the hundreds of other types of sharks that inhabit the world's oceans. Written by two of the world's leading authorities and superbly illustrated by wildlife artist Marc Dando, this is the first comprehensive field guide to all 440-plus shark species. Color plates illustrate all species, and detailed accounts include diagnostic line drawings and a distribution map for each species. Introductory chapters treat physiology, behavior, reproduction, ecology, diet, and sharks' interrelationships with humans. * More than 125 original full-color illustrations for fast and accurate identification of each shark family * Over 500 additional drawings illustrating physical features from different angles * Clear identification information for each species with details of size, habitat, behavior, and biology * Quick ID guide helpful for differentiating similar species * Geographic distribution maps for each species * For professional and amateur shark enthusiasts

Various parallels have been drawn between wolves and humans from the perspective of their social organisation. Therefore, studying wolves may well shed light on the evolutionary origins of complex human cognition and, in particular, on the role that cooperation played in its development. Humans closely share their lives with millions of dogs - the domesticated form of wolves. Biologically, wolves and dogs can be considered to be the same species; yet only dogs are suitable living companions in human homes, highlighting the importance of cognitive and emotional differences between the two forms. The behaviour of wolves and dogs largely depends on the environment the animals grew up and live in. This book reviews more than 50 years of research on the differences and similarities of wolves and dogs. Beyond the socio-ecology, the work explores different theories about when and how the domestication of wolves might have started and which behaviours and cognitive abilities might have changed during this process. Readers will discover how these fascinating animals live with their conspecifics in their social groups, how they approach and solve problems in their daily lives and how they see and interact with their human partners.

More than 1 000 mammal species occur in Africa south of the Sahara Desert. These creatures vary in size from the massive elephant to the tiniest bats, shrews and mice. A Photographic Guide to Mammals of Southern, Central and East Africa was compiled with a view to easing identification of many of the larger and more conspicuous mammals in the region, as well as some of the smaller and more unusual ones.

This compact, easy-to-use guide features:

- 152 of the region's mammal species

- key identification features showing how to differentiate between similar species

- distribution maps and a list of major parks and reserves indicating where species are likely to be seen

- quick reference key on inside cover

- thumbnail silhouettes of each family group for quick identification

This new revised edition is an ideal pocket-sized travelling companion for nature lovers and visitors to nature reserves and wildlife areas.

Chondrichthyans possess unique anatomical features compared to other vertebrates, in particular a fully cartilaginous skeleton and a permanently renewed dentition. These characteristics make the fossilization of whole bodies difficult and consequently their fossil record consists mainly of a large number of isolated teeth. The study of their dentition is therefore of primary interest for our understanding of the evolution of this group. Beyond the dental morphology, the structure of the tissues composing the dentition has proved an important source of information, sometimes difficult to interpret, on the eating habits and the paleobiology of these animals. This book makes a thorough review of the existing theories in this field of research as well as introducing new elements from more recent studies. Through close reference to the fossil record of ancient selachians it examines what the study of dental tissue in cartilaginous fish can tell us about the evolution and the past biology of these animals, as well as what we can learn about the evolution of teeth themselves.

We cannot catechise our stony ichthyolites, as did the necromantic lady of the Arabian Nights did the coloured fishes of the lake which had once been a city, when she touched their dead bodies with her wand, and they straightaway raised their heads and rephed to her queries. We would have many a question to ask them if we could - questions never to be solved. Hugh Miller, The Old Red Sandstone When I started this book in 1991, the subject of vertebrate origins was fusty and unfashionable. Early drafts for this preface read like an extend ed complaint at the lot of traditional morphologists, cast aside by the march of modern molecular biology. But no longer - this book should reach you at a time of renewed inter est in the origin of the vertebrates, our own particular corner of creation. For although the topic has excited interest for well over a century, molec ular biology has only lately achieved the maturity necessary to test its predictions. As a legitimate field of study, it is fashionable again."

Shorebirds, or waders, are a large group of small to medium-sized birds that occur worldwide, in a wide range of predominantly coastal or wetland habitats. Some species are largely sedentary whilst others are amongst the world's most migratory bird species, travelling thousands of kilometres in a few days. In addition to describing physical behavioural traits such as feeding, breeding, migration, and particular physiological adaptations, Shorebirds in Action also covers territorial behaviour both when feeding and breeding. There is detailed discussion of the range of species and their different lifestyles together with feeding strategies, flocking, roosting and the avoidance of predators. The seasonal features of shorebirds' lives are included, such as the various plumages that they have when breeding, or not breeding, together with the intervening periods of moult, during which the birds change from one plumage to the next.Shorebirds in Action is in two parts - firstly basic behavioural information and then a photographic section that explains the specific behaviour being illustrated for that particular shorebird at the time the photo was taken.Consequently, the book can be read as a general text, split into chapters that provide the basic behavioural information and also by reference to the extended photograph captions which explain the details of the particular behaviour shown. The book contains excellent photographs of about 180 shorebird species - over three-quarters of the world's total - and therefore provides a general reference for the identification of shorebird species and the recognition of their various plumages. It will be relevant to readers worldwide, including Europe, North America and Australasia. This comprehensive work can be read as a general text and also the photographs can be enjoyed separately in their own right. Detailed references to source material are provided.

With more than 15,000 species, nearly a quarter of the total number of vertebrate species on Earth, freshwater fishes are extremely varied. They include the largest fish species, the beluga at over 7 meters long, and the smallest, the Paedocypris at just 8 millimeters, as well as the carnivorous, such as the piranha, and the calm, such as the Chinese algae eater. Certain species evolve rapidly, cichlids for example, while others transform very slowly, like lungfish. The fossils of these animals are very diverse in nature, sometimes just small scattered bones where sites correspond to ancient river beds or magnificent fossils of entire fish where there was once a lake. This book covers the history of these fishes over the last 250 million years by exploring the links between their biological evolution and the paleogeographic and environmental transformations of our planet, whether these be gradual or sudden.

This book is the first veterinary textbook dedicated to nursing care plans. It offers a broad overview of the theory and practice of care planning in veterinary nursing, answering three key questions: What are nursing care plans? Why should nursing care plans be used in practice? How should nursing care plans be used in practice? Author Helen Ballantyne provides basic definitions and explanations which will be useful to those unfamiliar with nursing care plans. For those veterinary nurses and technicians who are using nursing care plans, the content stimulates debate and discussion, by covering some of the philosophical and theoretical aspects of nursing and drawing comparisons and contrasts between the veterinary and human nursing roles and contexts. There is a pressing need for veterinary nurses to establish themselves as professionals and develop their unique role within the veterinary care team. Nursing care plans are a core tool to support that development. It is hoped that veterinary nurses may borrow tools from the pages of this book or use it as a resource design their unique care plans: either way, this practical guide will support the application of care planning, no matter the species of the animal kingdom for whom you are caring.

Gorilla Pathology and Health: With a Catalogue of Preserved Materials consists of two cross-referenced parts. The first, the book itself, is a review of pathological changes and tissue responses in gorillas (Gorilla gorilla and G. beringei), with an emphasis on free-living animals, but also with reference to those in captivity. The comparative aspects are discussed, stressing the relevance of research to both gorillas and humans. What makes the publication truly unique, however, is the second part, a comprehensive descriptive catalogue of the location and nature of gorilla material in museums and scientific institutions throughout the world. This is of great consequence because free-living gorillas are strictly conserved with restricted access, so the location of a wealth of preserved tissues and other material that has been collected over the decades is a great benefit for research and study. This book can, and should, be used to gain cardinal knowledge regarding the biology and pathology of this genus. The combination of book and catalogue in this extensive compilation makes it an invaluable tool for all those concerned with the health, welfare, and conservation of gorillas, one of our nearest living relatives.

The fossil record of giant flightless birds extends back to the Late Cretaceous, more than 70 million years ago, but our understanding of these extinct birds is still incomplete. This is partly because the number of specimens available is sometimes limited, but also because widely different approaches have been used to study them, with sometimes contradictory results. This book summarizes the current knowledge of the paleobiology of seven groups of giant flightless birds: Dinornithiformes, Aepyornithiformes, Dromornithidae, Phorusrhacidae, Brontornithidae, Gastornithidae and Gargantuavis. The first chapter presents the global diversity of these birds and reviews the tools and methods used to study their paleobiology. Chapters 2 to 8 are each dedicated to one of the seven groups of extinct birds. Finally, a conclusion offers a global synthesis of the information presented in the book in an attempt to define a common evolutionary model.

This book offers an accessible and up-to-date reference on primate zoonoses. Recent years have witnessed a rise in human diseases zoonotically transferred from animals, with wild primates implicated in the spread of numerous newly emerging infections. The authors go beyond simply providing an inventory of diseases, helping readers to understand how and why they are transmitted. Important consideration is given to the contemporary cultural and ecological factors involved.

The names given to the variety of man-like fossils known to scientists should reflect no more than scientific views of the nature of human evolution. However, often in the past these names have also reflected confusion regarding the basic principles of scientific nomenclature; and the matter has been further complicated by the many new finds of recent decades. It is the unique purpose of this book to clarify the present state of knowledge regarding the main lines of human evolution by expressing what is known (and what is surmised) about them in appropriate taxonomic language. The papers in this volume were prepared by the world's leading authorities on the subject, and were revised in the light of discussions at a remarkable conference held in Austria in 1962 under the auspices of the Wenner-Gren Foundation. The authors review first the meaning of taxonomic statements as such, and then consider the substance of our present knowledge regarding the number and characteristics of species among living and extinct primates, including man and his ancestors. They also examine the relationship of behavior changes and selection pressures in evolutionary sequences. Ample illustrations, bibliographies and an index enhance the permanent reference value of the book, which will undoubtedly prove to be among the fundamental paleoanthropological works of our time.
