Weighing as much as 2,000 pounds and reaching lengths of over seven feet, leatherback turtles are the world’s largest reptile. These unusual sea turtles have a thick, pliable shell that helps them to withstand great depths—they can swim more than one thousand meters below the surface in search of food. And what food source sustains these goliaths? Their diet consists almost exclusively of jellyfish, a meal they crisscross the oceans to find. Leatherbacks have been declining in recent decades, and some predict they will be gone by the end of this century. Why? Because of two primary factors: human redevelopment of nesting beaches and commercial fishing. There are only twenty-nine index beaches in the world where these turtles nest, and there is immense pressure to develop most of them into homes or resorts. At the same time, longline and gill net fisheries continue to overwhelm waters frequented by leatherbacks. In The Leatherback Turtle, James R. Spotila and Pilar Santidrián Tomillo bring together the world’s leading experts to produce a volume that reveals the biology of the leatherback while putting a spotlight on the conservation problems and solutions related to the species. The book leaves us with options: embark on the conservation strategy laid out within its pages and save one of nature’s most splendid creations, or watch yet another magnificent species disappear.

Written by two of the Southeast's foremost authorities on sea turtle conservation, this is an accessible, fully illustrated guide to the species that frequent the Atlantic and Gulf Coasts of the United States. No one who encounters a sea turtle soon forgets it. The leatherback, for instance, can grow to huge proportions, commonly approaching eight feet in length and more than half a ton in weight. Powerful swimmers, they are also among the deepest divers of all air-breathing sea creatures. Despite these assets, the survival of the leatherback, like that of all sea turtle species, is under constant threat from commercial fishing operations, overdevelopment of nesting grounds, pollution, and predation by introduced species. The guide opens with comprehensive coverage of the sea turtle's evolution, juvenile and adult life cycles, nesting, diet and feeding, disease and parasites, predators, and conservation issues. Each subsequent chapter is dedicated to a particular turtle species: loggerhead, leatherback, Kemp's ridley, green sea turtle, hawksbill, and olive ridley. The account of each species describes distribution, habitats, general appearance, life history and behavior, and conservation. For each species, photographs of hatchlings and adults and a map showing distribution and migration provide further information. Sea turtles have been swimming the seas for one hundred million years. Yet all of the species in this book—indeed, all sea turtles worldwide—are on U.S. and international endangered lists. Biologists Carol Ruckdeschel and C. Robert Shoop have dedicated their careers to learning about sea turtles—and to ensuring that we understand that we are stakeholders in the fate of these ancient creatures. With this guide in hand, readers will be better equipped to understand sea turtle biology and support sea turtle conservation efforts.

The smallest of the sea turtles, olive and Kemp’s ridleys are the only marine turtles to exhibit mass-nesting behavior, known as arribadas. This fascinating phenomenon, during which one could literally walk shell-to-shell across a beach, is considered one of the most amazing wonders of nature. In Biology and Conservation of Ridley Sea Turtles, Pamela T. Plotkin brings together the world’s experts on the genus Lepidochelys to present the first comprehensive, book-length examination of these fascinating animals. Featuring the writings of noted experts including Peter C. H. Pritchard, Jack Frazier, Rene Márquez-M., and Donna J. Shaver, the volume synthesizes over a half century of research. With chapters focused on evolution, development, genetics, physiology, reproduction, migration, and conservation, this book combines a wealth of knowledge and describes an agenda for further research. An integral part of oceanic ecosystems, ridleys present challenges for conservation. Olive ridleys are abundant in some areas and declining in others, whereas Kemp’s ridleys are endangered but slowly recovering. Both face beach-based threats and are prone to capture by commercial fisheries. Here Plotkin and her colleagues reveal the nature of these species and the steps needed to make sure they remain a permanent part of the marine environment.

Sea turtles have existed since the time of the dinosaurs. But now, suddenly, the turtles are dying, ravaged by a mysterious plague that some biologists consider the most serious epidemic now raging in the natural world. Perhaps most important, sea turtles aren't the only marine creatures falling prey to deadly epidemics. Over the last few decades diseases have been burning through nearshore waters around the world with unprecedented lethality. What is happening to the sea turtle, and how can it be stopped? In this fascinating scientific detective story, Osha Gray Davidson tracks the fervent efforts of the extraordinary and often quirky scientists, marine biologists, veterinarians, and others racing against the clock to unravel a complicated biological and environmental puzzle and keep the turtles from extinction. He follows the fates of particular turtles, revealing their surprisingly distinct personalities and why they inspire an almost spiritual devotion in the humans who come to know them. He also explores through vivid historical anecdotes and examples the history of man's relationship to the sea, opening a window onto the role played by humans in the increasing number of marine die-offs and extinctions. Beautifully written, intellectually provocative, Fire in the Turtle House reveals how emerging diseases wreaking havoc in the global ocean pose an enormous, direct threat to humanity. This is science journalism at its best.

This second edition of International Environmental Law, Policy, and Ethics revises and expands this groundbreaking study into the question of why the environment is protected in the international arena. This question is rarely asked because it is assumed that each member of the international community wants to achieve the same ends. However, in his innovative study of international environmental ethics, Alexander Gillespie explodes this myth. He shows how nations, like individuals, create environmental laws and policies which are continually inviting failure, as such laws can often be riddled with inconsistencies, and be ultimately contradictory in purpose. Specifically, he seeks a nexus between the reasons why nations protect the environment, how these reasons are reflected in law and policy, and what complications arise from these choices. This book takes account of the numerous developments in international environmental law and policy that have taken place the publication of the first edition, most notably at the 2002 World Summit on Sustainable Development and the 2012 'Rio + 20' United Nations Conference on Sustainable Development. Furthermore, it addresses recent debates on the economic value of nature, and the problems of the illegal trade in species and toxic waste. The cultural context has also been considerably advanced in the areas of both intangible and tangible heritage, with increasing attention being given to conservation, wildlife management, and the notion of protected areas. The book investigates the ways in which progress has been made regarding humane trapping and killing of animals, and how, in contrast, the Great Apes initiative, and similar work with whales, have failed. Finally, the book addresses the fact that while the notion of ecosystem management has been embraced by a number of environmental regimes, it has thus far failed as an international philosophy.

Massentierhaltung, Fleischskandale, Tierversuche – unser Umgang mit Tieren ist längst kein Nischenthema mehr, für das sich lediglich Aktivisten oder Ethiker interessieren, sondern steht im Fokus breiter öffentlicher Debatten. Allerdings konzentrieren sich die Diskussionen zumeist auf Fragen der Moral, darauf, welche moralischen Rechte und Interessen wir Tieren aufgrund ihrer Eigenschaften und Fähigkeiten – zum Beispiel Schmerzen zu empfinden – zuschreiben müssen und welche moralischen Pflichten sich daraus für uns ergeben. Sue Donaldson und Will Kymlicka gehen weit darüber hinaus und behaupten, dass Tiere auch politische Rechte haben. Im Rückgriff auf avancierte Theorien der Staatsbürgerschaft argumentieren sie dafür, ihnen neben unverletzlichen Grundrechten einen je gruppenspezifischen politischen Status zuzusprechen. Das heißt konkret: Bürgerrechte für domestizierte Tiere, Souveränität für Gemeinschaften von Wildtieren sowie ein »Stammgastrecht« für jene, die zwar nicht domestiziert sind, aber in unmittelbarer Nachbarschaft zu uns leben. »Zoopolis« macht auf so kluge wie eindringliche Weise ernst mit der Tatsache, dass wir mit den Tieren untrennbar verbunden sind. Elegant und keineswegs nur für Spezialisten geschrieben, entwirft es eine neue, folgenreiche Agenda für das künftige Zusammenleben mit diesen Geschöpfen, denen wir mehr schulden als unser Mitleid. Das Tier, so sagt dieses Buch, ist ein genuin politisches Wesen. Wir schulden ihm auch Gerechtigkeit.

Ständige Ablenkung ist heute das Hindernis Nummer eins für ein effizienteres Arbeiten. Sei es aufgrund lauter Großraumbüros, vieler paralleler Kommunikationskanäle, dauerhaftem Online-Sein oder der Schwierigkeit zu entscheiden, was davon nun unsere Aufmerksamkeit am meisten benötigt. Sich ganz auf eine Sache konzentrieren zu können wird damit zu einer raren, aber wertvollen und entscheidenden Fähigkeit im Arbeitsalltag. Cal Newport prägte hierfür den Begriff "Deep Work", der einen Zustand völlig konzentrierter und fokussierter Arbeit beschreibt, und begann die Regeln und Denkweisen zu erforschen, die solch fokussiertes Arbeiten fördern. Mit seiner Deep-Work-Methode verrät Newport, wie man sich systematisch darauf trainiert, zu fokussieren, und wie wir unser Arbeitsleben nach den Regeln der Deep-Work-Methode neu organisieren können. Wer in unserer schnelllebigen und sprunghaften Zeit nicht untergehen will, für den ist dieses Konzept unerlässlich. Kurz gesagt: Die Entscheidung für Deep Work ist eine der besten, die man in einer Welt voller Ablenkungen treffen kann.
