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.
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.

In this comprehensive account of olfactory communication and territorial behavior in the Mongolian gerbil, Del Thiessen and PaulineYahr provide the first detailed study of the neurological and physiological mechanisms that control these basic functions. In addition to explaining the links between hormones, genes, olfactory cues, and territorial acts, they also offer a more general picture of gerbil behavior, as well as a brief look at other mammalian species that communicate social status by way of olfactory messages. Territorial behavior, as defined by the authors, includes all acts that are restricted to a particular area and are crucial for successful reproduction. In the Mongolian gerbil, and probably in other mammals as well, territoriality is controlled by sex hormones acting on specific areas of the central nervous system. Hormones from the gonads apparently act in the brain by altering the genetic apparatus controlling biochemicals used in neural communication. Without these hormones, the animal is socially inert and unable to transmit genes to the next generation. The authors conclude from the results of over ten years of investigation that the most complex social interactions depend on the integrity of the hormone system and its constant tuning by olfactory stimuli. The book incorporates a review of all previously known studies of gerbil behavior and representative data for many other scent-marking species. A stereotaxic brain atlas for the gerbil is a feature that will be especially helpful to other researchers. The book's eclectic nature should make it valuable to anyone concerned with territorial behavior, hormones and behavior, or brain processes, as well as to those who are specifically interested in the Mongolian gerbil.
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.
Atlas of the Anatomy of Dolphins and Whales is a detailed, fully illustrated atlas on the anatomy and morphology of toothed and whalebone whales. The book provides basic knowledge on anatomical structures, in particular, soft tissues, and functions as a standalone reference work for dissecting rooms and labs, and for those sampling stranded and by-caught dolphins in the field. As a companion and supplement to Anatomy of Dolphins: Insights into Body Structure and Function, this atlas will be of great interest to the scientific community, including veterinarians and biologists, as a book of reference. With a modern approach to dolphin anatomy and morphology, this atlas provides the extensive knowledge necessary to practitioners and theoretical scientists such as evolutionary biologists. The conceptual clarity, precision, and comprehensive and updated display of the topographical anatomy of the body of cetaceans in the atlas support and illustrate the authors' related work, serving as a comprehensive reference for those who are more specifically interested in the details of the anatomy and morphology of porpoises, dolphins and whales.
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.

'This long-awaited update to the acclaimed first edition is the definitive guide to a complex and intriguing family. The species accounts and taxonomic treatments have been fully revised in line with recent studies, and the all-new plates and photos complete this remarkable work. Highly recommended.' - Dominic Mitchell Beautiful, colourful, often fearless hunters of large insects and small vertebrates, shrikes are among the most admired of all avian groups. The group is widespread (particularly in the Old World) with a large number of species, though many populations have plummeted in recent years, especially in Europe. This is a second edition of Norbert Lefranc's Shrikes, fully updated from its 1997 predecessor. The introductory texts have been significantly expanded and six new sections have been added in the species accounts: vagrancy, foraging behaviour, breeding success, population trends, conservation and taxonomic notes. Special attention has been given to the latest developments in shrike systematics, not forgotten by the DNA revolution. The species accounts give information about the past and current distribution, along with threats and conservation status. Detailed and fully revised maps accompany the authoritative text, along with hundreds of high-quality photos showcasing racial and ageing differences as well as interesting aspects of shrike behaviour. An exceptional new series of plates by Tim Worfolk have been created, with more individual plumages shown than in the previous edition. This beautiful book represents the definitive account of shrikes and their relationships, appearance, conservation and lifestyle; it will be treasured by birdwatchers and professional ornithologists alike.

The present work evaluates the toxic effects of some environmental stressors on fish eggs and larvae and describes the biomarker responses of fish from locations with varying levels of pollution. Development of the main groups of biomarkers is discussed. The book demonstrates general trends and specific peculiarities of biomarker induction in early fish life and their association with the animal's developmental stages. It addresses responses of fish eggs and larvae to pollution under experimental conditions and presents information obtained from in situ studies. Chapters describe xenobiotics accumulation, anoxia and hypoxia, increasing temperature, eutrophication, and other unfavorable environmental factors, including biotic and abiotic factors, and their impact on fish embryos. They also examine fluctuations in biomarker levels in fish eggs and larvae that have been impacted by climate changes and discuss possible scenarios, especially for fish population size, reproduction, growth, development and biodiversity.
Wolves are controversial figures worldwide and much effort has focused on how to conserve them while addressing public concerns. With its solitary habits and fruit-eating diet, the endangered maned wolf roams the South American grasslands and swamps, playing a vital part in maintaining biodiversity hotspots. Compared to the grey wolf, little is known about its relationship with local people and the environment and the reasons for its decline, making research about this unique species an urgent concern. Ecology and Conservation of the Maned Wolf: Multidisciplinary Perspectives gathers the work of leading researchers from diverse disciplines and countries, covering up-to-date research on the biology, ecology, and conservation of the maned wolf. It presents innovative insights that can benefit conservation strategies and offers perspectives for the future of the species. The book is divided into three parts. Part I explains the general issues concerning the maned wolf: population viability, the relationship between maned wolves and people, and the management of captive maned wolves. It also reviews current aspects of species biology, including conservation genetics, feeding ecology, social structure and reproduction, and conservation medicine. Part II contains case studies that present knowledge gathered from conservation programs and field research in all countries where the species is currently found-Brazil, Uruguay, Argentina, Bolivia, and Paraguay. Part III offers perspectives from diverse fields of research, exploring the challenges and opportunities connecting maned wolf conservation efforts with those of its habitat and of other endangered species. This includes education and communication tools, the application of human dimensions research to maned wolf conservation, ethnoconservation perspectives, and the ecological and socioeconomic challenges to the conservation of the cerrado habitat.

The combination of authoritative text and superb artwork will set new standards for South American field guides.
Chimpanzees, including common chimpanzees and bonobos, are our closest living relatives. This book, which is the first photographic and descriptive musculoskeletal atlas of the genus Pan, adopts the same format as the photographic atlases of Gorilla and Hylobates previously published by the same authors. These three books are part of a series of monographs that will set out the comparative and phylogenetic context of the gross anatomy and evolutionary history of the soft tissue morphology of modern humans and their closest relatives. The atlas, which includes detailed high-quality photographs of musculoskeletal structures from most anatomical regions of the body as well as textual information about the attachments, innervation, function and weight of the respective muscles, is based on dissections of up to 12 chimpanzees and on an extensive review of the literature. It provides an updated review of the anatomical variations within chimpanzees as well as an extensive list of the synonyms used in the literature. The book is designed for students, teachers and researchers studying primatology, comparative anatomy, functional morphology, zoology, and physical anthropology and to medical students, doctors and researchers who are curious about the origin, evolution, homology and variations of the musculoskeletal structures of modern humans.
A comprehensive handbook covering all aspects of the conservation of Barn Owls.

Essential reading for ecologists, planners, land managers and ornithologists.
Seabirds are the living links between land, air and sea. They enjoy a freedom that even humans, with all our technological assistance, can barely imagine. Many species travel mind-boggling distances across the length and breadth of our planet before returning to land to breed in large, deafening and confusingly crowded colonies. Yet within this commotion each mated pair forms a bond of extreme closeness and tenderness that survives separation each winter and may persist for decades. The long and geologically varied coastline of the British Isles provides homes for internationally important numbers of breeding seabirds. Visiting their colonies is always unforgettable, whether they are cliff-faces packed with Guillemots, islands white-capped by clustered Gannets on their nests, flat beaches crowded with screaming Arctic Terns or seaside rooftops overlaid with a second townscape of nesting gulls. The changing fortunes of these seabird cities reveal to us the health of the vast, unseen but incredibly rich marine world that surrounds us. RSPB Seabirds showcases some of our most exciting and enigmatic bird species as vital and living components of one of our greatest natural assets: our coastline. The author presents detailed biographies of all the seabird species that breed in and around the British Isles, and also looks at the many species that breed elsewhere but which, regularly or occasionally, visit British waters. Every page of this sumptuous book features beautiful photographs of wild seabirds engaged in their daily work of hunting, travelling, protecting themselves and their territories, courting and raising a family.
Chimpanzees fascinate people for many reasons. We are struck by the apes' resemblance to humanity, as seen in their use of tools and their complex social lives, and we are moved by the threats that human activity poses to them. Our awareness of our closest living relatives testifies to the efforts of the remarkable people who study these creatures and work to protect them. What motivates someone to dedicate their lives to chimpanzees? How does that reflect on our own species? This book brings together a range of chimpanzee experts who tell powerful personal stories about their lives and careers. It features some of the world's preeminent primatologists-including Jane Goodall and Frans de Waal-as well as representatives of a new generation from varied backgrounds. In addition to field scientists, the book features anthropologists, biologists, psychologists, veterinarians, conservationists, and the director of a chimpanzee sanctuary. Some grew up in the English countryside, others in villages in Congo; some first encountered chimpanzees in a zoo, others in the forests surrounding their homes. All are united by a common purpose: to study and understand chimpanzees in order to protect them in the wild and care for them in zoos and sanctuaries. Contributors share what inspired them, what shaped their career choices, and what motivates them to strive for solutions to the many challenges that chimpanzees face today.
A remarkable exploration of naturalized parrots, among the most widely distributed birds in the world There are more than 350 species of parrots in the world, and approximately 300 of these species have been transported to other countries through the caged pet trade. Whether through escaped captivity or purposeful release, many of these parrots are now breeding in new habitats. Indeed, no less than 75 species of parrots have established breeding populations in countries where they were introduced, and parrots are now among the most widely distributed group of birds. Naturalized Parrots of the World is the first book to examine this specific avian population. Bringing together the work of leading researchers in one convenient volume, this book explores the biology of naturalized parrots and their interactions with native ecosystems. Experts discuss the global distribution of parrots, their genetics, conservation implications, and human responses to these birds. They also consider debates surrounding management issues and the lack of consensus around nonnative species in the wild. Later chapters feature case studies of the two most successful species-the Rose-ringed Parakeet and Monk Parakeet-as well as studies of the introduced parrot species located in specific countries and regions, including the United States, United Kingdom, Spain, Portugal, northern Europe, South Africa, and Australia. Highlighting critical aspects of conservation biology and biodiversity, Naturalized Parrots of the World will be an invaluable resource for parrot owners, ornithologists, conservation biologists, and birdwatchers.
Rats have long been recognized as a valuable biomedical research model, notably in the investigation of aging, toxicology, addiction, and common human diseases such as diabetes and hypertension. In many instances, individuals conducting such research studies are charged with important responsibilities, including animal facility management, animal husbandry, veterinary care, regulatory compliance, and various experimental methodologies. With the advent of genetic manipulations and biomedical research technological advances such as bioimaging, the versatility and usefulness of the rat as an animal model has soared. The Laboratory Rat, Second Edition captures the multiple advances in this important animal model's husbandry, veterinary care, and experimental methodology. This edition features augmented, expanded, and novel information on biology, anesthesia, analgesia, and experimental techniques benefiting personnel working with rats-from the animal care staff to the researcher and everyone in between. The book is also extremely useful to institutional animal care and use program supporters and elements, including animal care and use committees, institutional officials, occupational health and safety professionals, veterinary technicians, and veterinarians.
