With its iconic appearance and historic popular appeal, the giraffe is the world's tallest living terrestrial animal and the largest ruminant. Recent years have seen much-needed new research undertaken to improve our understanding of this unique animal. Drawing together the latest research into one resource, this is a detailed exploration of current knowledge on the biology, behaviour and conservation needs of the giraffe. Dagg highlights striking new data, covering topics such as species classification, the role of infrasound in communication, biological responses to external temperature changes and motherly behaviour and grief. The book discusses research into behaviour alongside practical information on captive giraffe, including diet, stereotypical behaviour, ailments and parasites, covering both problems and potential solutions associated with zoo giraffe. With giraffe becoming endangered species in Africa, the book ultimately focuses on efforts to halt population decline and the outlook for conservation measures.

The book provides up-to-date summaries on the main systems of blood group antigens and MHC molecules. The human systems are used to explain the necessary background knowledge and the systems in nonhuman primates are then described and compared. The emphasis is on the molecular nature of the gene products, the evolutionary relationships among the various systems, and the presumed mechanims by which the systems have evolved. All articles are written in such a way that they can serve as an introduction to the field for nonexperts and at the same time as a handbook for experts. Numerous tables, diagrams, and figures provide overviews of structure, distribution in different species, lists of known forms, and evolutionary relationships. Extensive reference lists guide the reader through the literature on each topic.

The book aims at synthesizing our current knowledge of Acipenser sturio and its management. This species, one of the most widespread sturgeon species all over Western Europe ranging from the Black Sea to the Baltic, is now on the verge of extinction. Major aspects of its biology and management, including mismanagement, are provided in a historic perspective. Similarly, the changes in the restoration programs (in situ and ex situ) initiated in France and Germany are presented. As the species occurred in sympatry with Acipenser oxyrinchus in Germany and Poland and very recently in France as well, a brief outlook on restoration-management programs of A. oxyrinchus are also provided for both North America and Northern European countries, namely Germany and Poland. As conservation-restoration actions go beyond scientific issues, non-governmental stakeholders and marine professional fishermen's organizations have also been asked to contribute, and the key role of a French-German cooperation plan is underlined. A part of the book is devoted to perspectives. Illustrations of the European sturgeon, mainly in photographs, but also in stamps and paintings, are presented.

The Horn of Africa has the highest endemism of any region in Africa, and around 70 species are found nowhere else in the world. Many of these are confined to the isolated highlands of Ethiopia and Eritrea, but a large number of larks specialise in the arid parts of Somalia and adjoining eastern Ethiopia, whilst the island of Socotra has its own suite of endemic species. The region is also an important migration route and wintering site for many Palearctic birds. This is the first field guide to the birds of this fascinating region, and a companion to Birds of East Africa by two of the same authors. Over 200 magnificent plates by John Gale and Brian Small illustrate every species that has ever occurred in the five countries covered by the guide, and the succinct text covers the key identification criteria. Special attention is paid to the voices of the species, and over 1000 up-to-date colour distribution maps are included. This long-awaited guide is a much-needed addition to the literature on African birds and an essential companion for birders visiting the region.

The polar bear, king of the Arctic, is one of the world's most recognizable animals. Images of the majestic beasts roaming across the ice cap, plunging into frigid waters, and playing with furry cubs have come to symbolize the beauty and grandeur of the Arctic. Andrew E. Derocher and Wayne Lynch have spent decades following the bears, and this book offers the most comprehensive and readable review of their biology, ecology, behavior, and conservation.

With gripping photographs by Lynch, a preeminent wildlife photographer, and the personal stories of Derocher, this book is as stunning to look at as it is fascinating to read. It weaves together their remarkable experiences with the latest research to tell the amazing story of these Arctic predators, tracing the animals back to their evolutionary roots and looking ahead to the future of polar bears on a warming planet Earth.

Through informative and engaging language, Derocher carefully explains the sea ice ecosystem that is essential to the survival of polar bears. He addresses the threat of global warming to the Arctic--home to polar bears for tens of thousands of years--and describes in impressive detail their feeding habits, distribution, den ecology, and reproduction. Lynch's vivid photographs capture all this and more as they chronicle the wide range of polar bear behavior, from family rituals to ferocious predatory practices.

Captivating, accurate, and inspiring, "Polar Bears" belongs in the hands of all who love the wild.

There are 10,500 species of bird worldwide and wherever they occur people marvel at their glorious colours and their beautiful songs. We also trap and consume birds of every kind. Yet birds have not just been good to eat. Their feathers, which keep us warm or adorn our costumes, give birds unique mastery over the heavens. Throughout history their flight has inspired the human imagination so that birds are embedded in our religions, folklore, music and arts. Vast in both scope and scale, Birds and People explores and celebrates this relationship and draws upon Mark Cocker's 40 years of observing and thinking about birds. Part natural history and part cultural study, it describes and maps the entire spectrum of our engagements with birds, drawing in themes of history, literature, art, cuisine, language, lore, politics and the environment. In the end, this is a book as much about us as it is about birds. Birds and People has been stunningly illustrated by one of Europe's best wildlife photographers, David Tipling, who has travelled in 39 countries on seven continents to produce a breathtaking and unique collection of photographs. The book is as important for its visual riches as it is for its groundbreaking content. Birds and People is also exceptional in that the author has solicited contributions from people worldwide. Personal anecdotes and stories have come from more than 650 individuals in 81 different countries. They range from university academics to Mongolian eagle hunters, and from Amerindian shamans to some of the most celebrated writers of our age. The sheer multitude of voices in this global chorus means that Birds and People is both a source book on why we cherish birds and a powerful testament to their importance for all humanity.

Birds are hosts to any parasites, internal and external. The parasites inevitably form a burden to the host bird and therefore may affect its ability to grow, survive and reproduce, its behaviour, and the abundance and distribution of the whole species. In consequence, bird-parasite systems have attracted attention from diverse fields, and the literature has been spread out in a wide range of specialized journals. The editors of this book have drawn together a comprehensive range of experts in the field to provide an invaluable reference of current work in bird-parasite interactions. The book is divided into four parts. The introduction provides the contemporary context of research in bird-parasite systems, and the following parts provide case studies which combine theoretical concepts with evidence from the literature and experimental data. Part 2, Ecology, examines the effects of parasites on individual fitness and population responses. Part 3 deals with behavourial responses to parasitism. The final part, sexual selection, pays particular attention to the significance of Hamilton and Zuk's predictions about the role of parasitism in choice and body ornamentation which have recen

This comprehensive introduction demonstrates the theoretical perspectives and concepts that are applied to primate behavior, and explores the relevance of non-human primates to understanding human behavior.

The genus Perca includes only three species of fish, but they are ubiquitous and abundant in freshwater and brackish environments of the northern hemisphere, from North America to Europe and Asia. These species are important both ecologically and economically. In Biology of Perch, world-renowned specialists review and update the biology of these fish. The book opens with a review of the genetic makeup of this complex assemblage from early post-glacial dispersion to the colonization of new habitats. The influences of geomorphological and biological factors on the dispersal of yellow perch (Perca flavescens) are explored. Two case studies exploit unique historical databases to follow population dynamics of yellow perch and European perch (P. fluviatilis) and to demonstrate how fisheries and habitat management can drastically influence the fate of fish populations. Three other chapters are dedicated to the general reproductive physiology, parasitology, and behavior of Perca species. The third species, the Balkhash perch (P. schrenkii), is a rare and threatened species of the Balkans, and a chapter is dedicated to its biology. The book ends with a review of the use of Perca species around the world as sentinels of ecological integrity and biomonitors in ecotoxicological studies.

This book focuses on latest information on the biology and ecology of the three bluefin tuna species: the Pacific (Thunnus orientalis), Atlantic (T. thynnus), and southern bluefin tuna (T. maccoyii). In the book, the phylogeny and basic ecological information such as early life history, age and growth, and food habits are covered. Information related to migratory ecology, and important biological aspects such as metabolism and energetics, swimming performance, schooling, visual physiology, and reproductive physiology are also included. Furthermore, new research insights about various kinds of mathematical models for bluefin tuna ecology are introduced. All the chapters are contributed by active scientists engaged in bluefin tuna research. The intent of this book is to contribute to a better understanding of the biology and ecology of bluefin tuna, and encourage undergraduate and graduate students who read this book to become bluefin tuna scientists who can contribute to further understanding of the biology and ecology of bluefin tuna.

Recent advances in fish cytogenetics have enhanced the interest in chromosome analysis in both fundamental (systematics and comparative genomics among fishes and other vertebrate groups) and applied (aquaculture, conservation and response to pollutants, whole genome sequencing of model fish species) research. Although the genomic material, the chromosomes, is basically the same in the various organisms, experience has clearly shown that fish chromosomes have to be handled with specific protocols. In laboratories around the world, traditional cytogenetic techniques and molecular cytogenetics have seen a vast improvement but the technical details and protocols are often not published in scientific journals because of constraints in format and size and therefore they are not accessible to the whole scientific community. These shortcomings are very well known to fish cytogeneticists and the idea to prepare a specific manual was first discussed during the first "Workshop of Fish Cytogenetics" held in Concarneau (France), in 1992. Resulting from the above workshop, a draft compilation of the techniques and protocols in fish cytogenetics available at that time had been produced and distributed privately, but never published. There does not exist, at present, any published handbook or manual specifically dealing with fish cytogenetics. This book fills this void by bringing together and updating the main techniques so that the traditional methods can be standardized. Moreover, this book includes novel developments or improvements; some of the protocols provided here are practically unknown to the scientific community and even now unpublished.

This book reexamines current knowledge on the evolution, ecology, and conservation biology of both New World vultures (Cathartidae) and Old World vultures (Accipitridae) and seeks answers to past and present regional extinctions, colorizations, and conservation questions. Extinct species of both families are examined, as is the disputed evidence for familial similarities and differences currently under review by geneticists and ornithologists. Conservation questions concern the extent to which recent land cover change (deforestation, urbanization, and desertification), wildlife depletions, and pollution have affected scavenging vultures. Such changes are examined as both positive and negative for vultures-a growing body of literature hints at the positive impacts of urban waste, more open forests, forest fires, landscape cultivation, road kills, and shore development, especially with increased attention to bird adaptation and "new" theories of adaptive management in conservation. These are contrasted with the conservation of other raptors and scavengers. Within new trends in conservation, with emphases on animal/human shared co-evolution in intensely habituated spaces, vulture conservation requires important new perspectives that contrast with the needs of other species conservation.

In the cold waters of the unforgiving North Atlantic Ocean, some of the heartiest humans of medieval days ventured out in search of whales. Through the centuries, people on both sides of the Atlantic became increasingly dependent on whale oil and other cetacean products. To meet this growing demand, whaling became ever more sophisticated and intense, leading to the collapse of what was once a seemingly inexhaustible supply of large cetaceans. Central to the whale's subsequent struggle for existence has been one species--the North Atlantic right whale. Conservationist David W. Laist now provides the first complete history of the North Atlantic right whale, from its earliest encounters with humans to its close brush with extinction, to its currently precarious yet hopeful status as a conservation icon. Favored by whalers because of their high yields of oil and superior baleen, these giants became known as "the right whale to hunt," and their numbers dwindled to a mere 100 individuals worldwide. Their dire status encouraged the adoption of a ban on hunting and a treaty that formed the International Whaling Commission. Recovery of the species, however, has proven elusive. Ship strikes and entanglement in commercial fishing gear have hampered herculean efforts to restore the population. Today, only about 500 right whales live along the US and Canadian Atlantic coasts--an improvement from the early twentieth century, but still a far cry from the thousands that once graced Atlantic waters. Laist's masterpiece features an incredible collection of photographs and artwork that give life to the fascinating history that unfolds in its pages. The result is a single volume that offers a comprehensive understanding of North Atlantic right whales, the role they played in the many cultures that hunted them, and our modern attempts to help them recover.

Fish constitute an important natural renewable resource and any reduction in their ability to propagate as a result of human interference may have significant socioeconomic consequences. The negative effect of human activity on sex differentiation and reproductive output in fish is so diverse that it has been difficult to encompass it in a single book. This book serves as the first attempt to do so. Unlike in mammals, the expression of a host of sex differentiation genes in fish is mostly controlled by environmental factors. Not surprisingly, environmental sex differentiation is ubiquitous in fish. Overexploitation by capture fisheries does not disrupt sex differentiation but crowding in aqua-farms does, by reducing accessibility to food supply. Some of the man-made chemicals routinely used worldwide mimic endogenous hormones. For example endosulfan, which is widely used in developing countries, disrupts endogenous hormones and feminizes fish. For the first time, this book views endocrine disruption from the point of labile early life and non-labile adult stages. It shows that sex can irreversibly be reversed, when exposed to endocrine disrupting chemicals (EDCs) during early labile stages but reversibly impairs reproductive output on exposure to EDCs during non-labile adult stage. A consequence of climate change, elevated temperature, and declining oxygen and pH levels is that it masculinises genetic female fish. Fish display a remarkable ability to postpone the labile period. Besides postponement, some primary and tertiary gonochores have two distinct labile periods amenable to temperature and hormonal manipulations. Hermaphrodites have retained the period until the end of the adult stage and are capable of sex change/reversal more than once in both male and female directions.

Immunity studies in sharks over the past three decades have produced some remarkable discoveries. If one message rings true, it is that alternative animal model systems, such as sharks and their relatives, have contributed very substantially to a better understanding of the development evolution of our own immune system. Immunobiology of the Shark describes the cellular, genetic, and molecular specifics of immune systems in sharks. Diverse approaches were employed to study the immunobiology of the shark from basic microscopic observations to detailed genome annotation. The book also raises a series of fascinating questions, which can be addressed experimentally using today's technology. This book will be a valuable resource for mainstream immunologists, comparative immunologists, geneticists, ecologists, evolutionary biologists, and investigators engaged in shark research. The book also aims to illustrate the magnificence of these animals as model systems and underscores the importance of their study to further understand their complex, and often enigmatic, biology.

Coordination in Human and Primate Groups presents one of the first collections of the different methods and approaches used to assess coordination processes in groups. Written by psychologists and primatologists, the book represents a broad range of coordination research fields such as social psychology, work and organizational psychology, medicine, primatology, and behavioral ecology. It is designed for researchers and practitioners interested in understanding the behavioral aspects of group coordination.
