Since the award-winning first volume, The Biology of Sharks and Their Relatives, published in 2004, the field has witnessed tremendous developments in research, rapid advances in technology, and the emergence of new investigators beginning to explore issues of biodiversity, distribution, physiology, and ecology in ways that eluded more traditional studies. As an entirely new companion volume, Sharks and Their Relatives II: Biodiversity, Adaptive Physiology, and Conservation brings you up to speed on these significant changes, specifically examining how elasmobranch fishes – the sharks, skates, rays, and chimaeras – successfully survive in a wide range of habitats. Emphasizes Conservation of Threatened Species This multidisciplinary volume begins by examining elasmobranch biodiversity patterns and their integrated sensory systems. It then explores the physiological adaptations – from unique sensory modalities to compensatory mechanisms for physiological and environmental stress – that make these animals particularly well-suited for the range of habitats where they are found, in both oceanic and freshwater realms. Features Established Researchers and Introduces New Pioneers in the Field The book then considers the human interactions and anthropogenic effects on worldwide elasmobranch populations and the potential extinction risks posed by increasing threats from changes in habitat, changes in water chemistry, and growing commercial exploitation. This text truly is unrivaled in terms of coverage and readability, and it is a must-have reference for marine biologists, fishery scientists, oceanographers, and also marine, zoo, and aquarium veterinarians. To address subject areas and subdisciplines where coverage was absent or superficial in volume one, Jeffrey Carrier and associates have assembled in the current volume a collection of works that reveal patterns of biodiversity, the physiological attributes that contribute to elasmobranchs’ successful exploitation of oceanic and freshwater realms, and the unique issues associated with the interaction between elasmobranchs and humans, all of this with overarching attention to issues of conservation. "We begin with chapters examining biodiversity. We have chosen to approach this discussion by presenting elasmobranchs as inhabitants of the range of zoogeographic provinces, realizing that significant overlap may occur for more pelagic species. This realization was reflected in the dialogue that occurred during preparation of the book between our chapter authors, and the recognition that many species simply cannot be confined to a specific habitat or range of habitats. We then continue by examining some of the unique physiological adaptations that allow these animals to exploit the range of habitats where they are found, from unique sensory modalities to compensatory mechanisms for physiological and environmental stress. "Our concluding section presents some of the challenges faced by members of these groups. We have asked our authors to consider human interactions and anthropogenic effects on worldwide populations and the potential extinction risks posed from survival under increasing threats from changes in habitat, changes in water chemistry, and increasing commercial exploitation. Conservation of species under threat remains a theme throughout the book. "Our authors represent an international group of investigators including established scientists whose work has been widely published and respected, and emerging younger scientists who have exploited recent advances in technology to ask and answer new questions as well as offering new insights and interpretations to enduring problems in the fields of ecology and physiology. We have asked them to be speculative and challenging, and we have asked them to predict future areas for investigation in hopes that their work will both inspire and provoke additional studies of these fascinating animals." - from the Preface
Virtually every area of research associated with sharks and their relatives has been strongly impacted by the revolutionary growth in technology. The questions we can now ask are very different than those reported even two decades ago. Modern immunological and genetic techniques, satellite telemetry and archival tagging, modern phylogenetic analysis, GIS, and bomb dating, are just a few of the techniques and procedures that have become a part of our investigative lexicon. A modern synthesis of the biology of Chondrichthyans, Biology of Sharks and Their Relatives, Second Edition discusses significant advances in the development and application of new molecular techniques to the understanding of the phylogenetic relationships among and between these groups. The book considers the effect of global changes on the status of sharks and their relatives, and how advances in technology and analytical techniques have changed not only how we approach problem solving and scientific investigations, but how we formulate questions. The book also introduces applications of new and novel laboratory devices, techniques, and field instruments. This second edition of the award winning and groundbreaking original exploration of the fundamental elements of the taxonomy, systematics, physiology, and ecology of sharks, skates, rays, and chimera, presents cohesive and integrated coverage of key topics and discusses technological advances used in modern shark research. Offering a well-rounded picture for students and researchers, and far above competitors in scope and research, this new volume holds a wealth of data on the current status of Chondrichthyan research and provides the basis and springboard for original research.

The key aim of this book is to explore the global conservation and management of sharks. There has been a rapid decline in populations of many shark species, while new science has emerged of the critical role they play in marine ecosystems. However, the authors show that conservation law and policy have been slow to develop, with only a small number of iconic species being protected worldwide. The increase in fishing impact – primarily through shark finning and by-catch - has led to shark conservation receiving greater international attention in recent years. The book explores our current knowledge and status of the law and science in relation to sharks with a particular focus on improving frameworks for their conservation and management. Recent trends are analysed, including shark finning bans that have been put in place in several countries, the widening number of nations establishing shark sanctuaries and the growth of shark-based tourism. The efficacy of current listing processes for endangered species and fisheries regulations is also examined. Tourism is explored as an alternative to fishing and the risks and impacts associated with this industry are analysed. Contributors include leading authorities from universities and conservation organizations in North America, Europe and Australia. A common theme is to emphasise the importance of collaborative governance between various interest groups and the need for inter-disciplinary research and management approaches that are necessary to address the decline in sharks.
Northeast Pacific Shark Biology, Research and Conservation, Part A, Volume 77 highlights the biological attributes of, and the conservation efforts targeted at, populations of vulnerable sharks in the Northeastern Pacific Ocean bordering the west coast of the United States, one of the most economically and ecologically important oceanic regions in the world. Updates in this new volume include chapters on Biodiversity, Conservation and Life History of Northeastern Pacific Chondrichthyans, a Review of current genetic analyses of Northeast Pacific sharks and conservation implications, and a section on the Trophodynamics and ecological impacts of eastern North Pacific sharks. Brings together subject experts on all aspects of shark biology, ecology, fishery management and conservation Summarizes current knowledge Focuses scientific attention on key issues embedded in the concept of shark conservation, both from a species and an ecosystem perspective
Winner of Choice Magazine’s Outstanding Academic Title award, January 2005! Sharks and their relatives are the subjects of tremendous interest. The public’s fascination is influenced by their roles in movies and popular literature, while the media races to cover stories of predators endangering helpless humans. The alarming threat to shark populations is also garnering significant publicity and leading to a worldwide increase in conservation initiatives. Finally, technological advances are impacting every area of shark research and revealing incredible secrets about these mysterious animals. These major factors indicate the need for a timely synthesis of the biology of sharks and their relatives. Biology of Sharks and Their Relatives brings together the latest information on the phylogeny, physiology, behavior, and ecology of sharks and their relatives, the skates, rays, and chimaeras. Written by a “Who’s Who” lineup in North American elasmobranch research, this single-source review of elasmobranch fishes presents cohesive and integrated coverage of key topics and discusses technological advances used in modern shark research. The text establishes relationships among the sharks and their relatives that dominate the Chondrichthyes, describes their functions and physiological processes, and examines issues relevant to managing depleted and threatened fisheries. Each of the 19 chapters includes a comprehensive review of the subject with extensive up-to-date citations. This authoritative book provides a synopsis of the current understanding of elasmobranch fishes while identifying gaps in our knowledge to stimulate further study. Its broad coverage and inclusive nature make this an important resource for marine and conservation biologists, fishery scientists, biological oceanographers, zoologists, ecologists, environmental planners, and students.
Answering every conceivable question about sharks, authors Gene Helfman and George H. Burgess describe the fascinating biology, behavior, diversity (there are more than 1,000 species worldwide), and cultural importance of sharks, their close relationship to skates and rays, and their critical role in healthy ecosystems. Helfman and Burgess take readers on a round-the-world tour of shark habitats, which include oceans as well as lakes and even rivers (as far up the Mississippi as St. Louis). They describe huge, ferocious predators like (Great) White and Tiger sharks and species such as Basking and Whale sharks that feed on microscopic prey yet can grow to lengths of more than 40 feet. The mysterious and powerful Greenland shark, the authors explain, reaches a weight of 2,200 pounds on a diet of seal flesh. Small (less than 2-foot long) Cookiecutter sharks attack other sharks and even take a chunk out of the occasional swimmer. Despite our natural fascination with sharks, we have become their worst enemy. Many shark species are in serious decline and a number are threatened with extinction as a result of overfishing and persecution. Sharks: The Animal Answer Guide presents a perfect mix of current science, history, anthropology, intriguing facts, and gripping photographs. Whether your fascination with sharks stems from fear or curiosity, your knowledge of these animals will improve immensely when you consult this book.

Agile, sleek, and precise, sharks display many qualities we can admire and appreciate. These marvels of evolution have adapted to thrive in every major aquatic realm on the planet, from frigid Arctic waters through temperate but stormy seas and on into the tropics. However, few places on Earth are home to the amazing diversity of shark species that beautify the shallow waters of Florida and the Bahamas. In this first-ever book dedicated to the sharks of this region, biologist Jeffrey C. Carrier reveals the captivating lives of these large marine predators and describes how they have survived for over 400 million years. Guiding readers through basic biology, key attributes, and identification tips, the book explores what makes sharks such successful apex predators. Carrier explains fascinating phenomena, including the reason for the bizarre shape of the hammerhead, how a bull shark is able to swim hundreds of miles up freshwater rivers, what lies behind sharks’ remarkable capability to learn and remember, and why many scientists believe that they are equipped with the most sophisticated sensory systems in the animal kingdom. With the stunning full-color underwater photography of Andy Murch, Jillian Morris, and Duncan Brake, Sharks of the Shallows brings boaters, fishers, divers, and shark lovers directly alongside these unfairly maligned creatures. And not a moment too soon! Sharks are experiencing stresses unlike any in their long history, and are struggling to survive in a changing ocean. They will continue to grace our coastlines only if we care enough to understand them.

This volume offers a collection of papers on the quantitative assessment of age and growth in Chondrichthyan fishes. It details new hard parts for assessments of age, such as caudal thorns; new techniques like bomb radiocarbon for validation; and reexaminations of previous age and growth models. It also examines the importance of assessing the precision and accuracy of statistical formulas, analyses, and models used in age and growth studies.
Krone der Schöpfung? Vor 100 000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies, und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70 000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens, und es war vor allem die Beschaffenheit seines Gehirns, die ihn zum Herren des Planeten und zum Schrecken des Ökosystems werden ließ. Bis heute hat sich diese Vorherrschaft stetig zugespitzt: Der Mensch hat die Fähigkeit zu schöpferischem und zu zerstörerischem Handeln wie kein anderes Lebewesen. Anschaulich, unterhaltsam und stellenweise hochkomisch zeichnet Yuval Harari die Geschichte des Menschen nach und zeigt alle großen, aber auch alle ambivalenten Momente unserer Menschwerdung.
In The Death and Life of Great American Cities durchleuchtet Jane Jacobs 1961 die fragwürdigen Methoden der Stadtplanung und Stadtsanierung in Amerika, der "New Yorker" nannte es das unkonventionellste und provozierendste Buch über Städtebau seit langem. Die deutsche Ausgabe wurde schnell auch im deutschsprachigem Raum zu einer viel gelesenen und diskutierten Lektüre. Sie ist jetzt wieder in einem Nachdruck zugänglich, mit einem Vorwort von Gerd Albers (1993), das nach der Aktualität dieser Streitschrift fragt.
Bob Woodward, die Ikone des investigativen Journalismus in den USA, hat alle amerikanischen Präsidenten aus nächster Nähe beobachtet. Nun nimmt er sich den derzeitigen Präsidenten vor und enthüllt den erschütternden Zustand des Weißen Hauses unter Donald Trump. Woodward beschreibt, wie dieser Präsident Entscheidungen trifft, er berichtet von eskalierenden Debatten im Oval Office und in der Air Force One, dem volatilen Charakter Trumps und dessen Obsessionen und Komplexen. Woodwards Buch ist ein Dokument der Zeitgeschichte: Hunderte Stunden von Interviews mit direkt Beteiligten, Gesprächsprotokolle, Tagebücher, Notizen – auch von Trump selbst – bieten einen dramatischen Einblick in die Machtzentrale der westlichen Welt, in der vor allem eines herrscht: Furcht. Woodward ist das Porträt eines amtierenden amerikanischen Präsidenten gelungen, das es in dieser Genauigkeit noch nicht gegeben hat.
This book presents a collection of writings by expert researchers from Canada, the United States, and Australia who are committed to finding common cause and common ground in the prevention of eating disorders and obesity. The ten chapters in this book seek to create a new public health approach to the prevention of weight-related disorders, one that counters the confusion and frustration from public policies, messages, and programs that recipients of prevention efforts often experience. The first section looks at prevention from a public health perspective, and the second section highlights theories from risk and resilience research that can inform the prevention of weight-related disorders. The contributions are varied in their theories and models, but woven throughout is the theme of collaboration in changing public institutions and social systems that promotes universal prevention and fosters mental health and resilience. Unique methods of linking systems and fostering partnerships across sectors and disciplines are highlighted, and readers are exposed to innovative ideas of how to move the field of prevention science forward to reduce the onset of negative body image, unhealthy weight management, eating disorders, and disordered eating. Preventing Eating-Related and Weight-Related Disorders is the second in a series of titles from The Community Health Systems Resource Group at The Hospital for Sick Children. This series will educate researchers, policy-makers, students, practitioners, and interested stakeholders on such topics as early intervention in psychosis, aggressive behaviour problems, eating-related disorders, and marginalized youth in educational contexts.
This classic four-volume series-from a pioneering ethnographer, first published in 1910-remains a foundational work of comparative mythology and religion for scholars and armchair anthropologists alike. Exploring the interconnections between myth and ritual in how and whom we may marry-as group marriage gave way to individual marriage-questions about religion and social structure became intertwined. In any case, this is a fascinating look at the social underpinnings common to all peoples around the globe. Volume II continues Frazer's ethnographic survey of totemism, here covering totemism in the South Pacific, India, and Africa. Scottish anthropologist SIR JAMES GEORGE FRAZER (1854-1941) also wrote the classic The Golden Bough (1890), Man, God, and Immortality (1927), and Creation and Evolution in Primitive Cosmogonies (1935).
