For over 350 million years, thousands of species of amphibians have lived on earth, but since the 1990s they have been disappearing at an alarming rate, in many cases quite suddenly and mysteriously. What is causing these extinctions? What role do human actions play in them? What do they tell us about the overall state of biodiversity on the planet? In Extinction in Our Times, James Collins and Martha Crump explore these pressing questions and many others as they document the first modern extinction event across an entire vertebrate class, using global examples that range from the Sierra Nevada of California to the rainforests of Costa Rica and the Mediterranean coast of North Africa. Joining scientific rigor and vivid storytelling, this book is the first to use amphibian decline as a lens through which to see more clearly the larger story of climate change, conservation of biodiversity, and a host of profoundly important ecological, evolutionary, ethical, philosophical, and sociological issues.

With over 7,000 known species, frogs display a stunning array of forms and behaviors. A single gram of the toxin produced by the skin of the Golden Poison Frog can kill 100,000 people. Male Darwin’s Frogs carry their tadpoles in their vocal sacs for sixty days before coughing them out into the world. The Wood Frogs of North America freeze every winter, reanimating in the spring from the glucose and urea that prevent cell collapse. The Book of Frogs commemorates the diversity and magnificence of all of these creatures, and many more. Six hundred of nature’s most fascinating frog species are displayed, with each entry including a distribution map, sketches of the frogs, species identification, natural history, and conservation status. Life-size color photos show the frogs at their actual size—including the colossal seven-pound Goliath Frog. Accessibly written by expert Tim Halliday and containing the most up-to-date information, The Book of Frogs will captivate both veteran researchers and amateur herpetologists. As frogs increasingly make headlines for their troubling worldwide decline, the importance of these fascinating creatures to their ecosystems remains underappreciated. The Book of Frogs brings readers face to face with six hundred astonishingly unique and irreplaceable species that display a diverse array of adaptations to habitats that are under threat of destruction throughout the world.

ONE OF THE NEW YORK TIMES BOOK REVIEW'S 10 BEST BOOKS OF THE YEAR A major book about the future of the world, blending intellectual and natural history and field reporting into a powerful account of the mass extinction unfolding before our eyes Over the last half a billion years, there have been five mass extinctions, when the diversity of life on earth suddenly and dramatically contracted. Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. This time around, the cataclysm is us. In The Sixth Extinction, two-time winner of the National Magazine Award and New Yorker writer Elizabeth Kolbert draws on the work of scores of researchers in half a dozen disciplines, accompanying many of them into the field: geologists who study deep ocean cores, botanists who follow the tree line as it climbs up the Andes, marine biologists who dive off the Great Barrier Reef. She introduces us to a dozen species, some already gone, others facing extinction, including the Panamian golden frog, staghorn coral, the great auk, and the Sumatran rhino. Through these stories, Kolbert provides a moving account of the disappearances occurring all around us and traces the evolution of extinction as concept, from its first articulation by Georges Cuvier in revolutionary Paris up through the present day. The sixth extinction is likely to be mankind's most lasting legacy; as Kolbert observes, it compels us to rethink the fundamental question of what it means to be human.

"John W. Wilkinson's very readable book covers every aspect of amphibian surveys, from planning through to data analysis and report writing. The comprehensive text includes methods applicable in habitats all over the world and should prove invaluable to a wide international readership." Trevor Beebee Amphibians are among the most globally endangered groups of vertebrates with more than one-third of species being assessed as declining or threatened. Often, amphibian declines can be attributed to a suite of interacting factors, many of which are human in origin, but further information is needed to elaborate the key causes and to discover ways of reversing declines. Robust surveys provide vital ecological and biological data on amphibian populations, and underpin the decisions made to protect species and reverse their declines. Ongoing monitoring informs land managers and decision makers about whether they are taking the right action. This book is designed to help you carry out amphibian surveying and monitoring so that the results of your surveys can be used effectively. Part 1 introduces amphibians: order Anura (frogs and toads); Caudata (newts and salamanders); and order Gymnophonia (caecilians). Part 2 is essential reading before you start surveying. It introduces the different types of survey and monitoring programmes and discusses survey aims and resources. It contains chapters on collecting and handling survey data; survey permissions and licencing; health and safety, and biosecurity; and handling amphibians. Part 3 discusses everything you need to know during your survey, and provides a detailed look at amphibian survey methods. Part 4 covers presenting and using your survey’s data to best effect. A useful resources section is also provided, with example survey forms and details of additional information resources that will optimize the impacts of your surveys. Key amphibian survey techniques are discussed with reference to published examples of successful surveys – so you’ll be able to choose what’s right for your situation. Tips on optimizing your survey effort and handling amphibians in the field are also included. Whether carrying out a student expedition project or seeking information to support the management of a protected area, this book contains essential advice from an amphibian ecologist who has encountered the same sorts of decisions you’ll face when planning your surveys.

Scores of wild species and ecosystems around the world face a variety of human-caused threats, from habitat destruction and fragmentation to rapid climate change. But there is hope, and it, too, comes in a most human form: zoos and aquariums. Gathering a diverse, multi-institutional collection of leading zoo and aquarium scientists as well as historians, philosophers, biologists, and social scientists, The Ark and Beyond traces the history and underscores the present role of these organizations as essential conservation actors. It also offers a framework for their future course, reaffirming that if zoos and aquariums make biodiversity conservation a top priority, these institutions can play a vital role in tackling conservation challenges of global magnitude. While early menageries were anything but the centers of conservation that many zoos are today, a concern with wildlife preservation has been an integral component of the modern, professionally run zoo since the nineteenth century. From captive breeding initiatives to rewilding programs, zoos and aquariums have long been at the cutting edge of research and conservation science, sites of impressive new genetic and reproductive techniques. Today, their efforts reach even further beyond recreation, with educational programs, community-based conservation initiatives, and international, collaborative programs designed to combat species extinction and protect habitats at a range of scales. Addressing related topics as diverse as zoo animal welfare, species reintroductions, amphibian extinctions, and whether zoos can truly be “wild,” this book explores the whole range of research and conservation practices that spring from zoos and aquariums while emphasizing the historical, scientific, and ethical traditions that shape these efforts. Also featuring an inspiring foreword by the late George Rabb, president emeritus of the Chicago Zoological Society / Brookfield Zoo, The Ark and Beyond illuminates these institutions’ growing significance to the preservation of global biodiversity in this century.

The research paper "Extinction Risk from Climate Change" published in the journal Nature in January 2004 created front-page headlines around the world. The notion that climate change could drive more than a million species to extinction captured both the popular imagination and the attention of policy-makers, and provoked an unprecedented round of scientific critique. Saving a Million Species reconsiders the central question of that paper: How many species may perish as a result of climate change and associated threats? Leaders from a range of disciplines synthesize the literature, refine the original estimates, and elaborate the conservation and policy implications. The book: examines the initial extinction risk estimates of the original paper, subsequent critiques, and the media and policy impact of this unique studypresents evidence of extinctions from climate change from different time frames in the pastexplores extinctions documented in the contemporary recordsets forth new risk estimates for future climate changeconsiders the conservation and policy implications of the estimates. Saving a Million Species offers a clear explanation of the science behind the headline-grabbing estimates for conservationists, researchers, teachers, students, and policy-makers. It is a critical resource for helping those working to conserve biodiversity take on the rapidly advancing and evolving global stressor of climate change-the most important issue in conservation biology today, and the one for which we are least prepared.
