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.

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.
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.
Over the last decade, the study of shark biology has benefited from the development, refinement, and rapid expansion of novel techniques and advances in technology. These have given new insight into the fields of shark genetics, feeding, foraging, bioenergetics, imaging, age and growth, movement, migration, habitat preference, and habitat use. This pioneering book, written by experts in shark biology, examines technologies such as autonomous vehicle tracking, underwater video approaches, molecular genetics techniques, and accelerometry, among many others. Each detailed chapter offers new insights and promises for future studies of elasmobranch biology, provides an overview of appropriate uses of each technique, and can be readily extended to other aquatic fish and marine mammals and reptiles.
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.

The large amount of information on fish reproduction available is not always readily accessible to all interested parties. Written to appeal to aquaculturalists, conservation managers, and scientific researchers, Methods in Reproductive Aquaculture provides an overview of available techniques and addresses ways to improve depleted stocks of endangered fish and other species. The book focuses on gamete quality and management, exploring new objectives and areas of application and research, and new tools to deal with some aspects in reproduction of aquatic species. It begins with an examination of basic methods and techniques for gamete extraction, mainly sperm collection and egg stripping in different species, then describes techniques of spawning stimulation in males and females. The volume then highlights sperm and egg quality evaluation and considers sperm analysis from a practical broodstock management point of view and in the selection of appropriate breeders. The book goes on to discuss techniques used for artificial fertilization and the procedures for obtaining modified offspring. It introduces cryopreservation procedures for sperm, oocytes, and embryos, then discusses the materials and facilities required for gamete preparation and freezing-thawing procedures. The book concludes with an extensive section detailing sperm cryopreservation protocols for fifty-six marine and freshwater species. Unique in its focus on both marine and freshwater aquaculture of fishes, the book provides information on endangered, highly profitable species for aquaculture or fisheries and species with high potential in laboratory research. Presenting the available information in an easily understandable way, this is not merely a techniques book, but also a complete guide to fish reproduction, gamete quality, and management.
