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.

Amphibians are among the most threatened groups of animals on earth. In part due to their highly permeable skin, amphibians are highly sensitive to environmental changes and pollution and provide an early-warning system of deteriorating environmental conditions. The more we learn about the impact of environmental changes on amphibians, the better we as humans will be able to arrest their demise, and our own. Status of Conservation and Decline of Amphibians brings together the current knowledge on the status of the unique frogs of Australia, New Zealand, and the Pacific. Although geographically proximate, each region presents unique challenges and opportunities in amphibian research and conservation. This book contributes to an understanding of the current conservation status of the amphibians of each region, aims to stimulate research into halting amphibian declines, and provides a better foundation for making conservation decisions. It is an invaluable reference for environmental and governmental agencies, researchers, policy-makers involved with biodiversity conservation, and the interested public.

The first volume of the series comprises the report to a task force of the World Conservation Union (IUCN) by a Canadian research group. The 29 papers include demographic and population studies, status reports, descriptions of methods, and studies or reviews of causes of amphibian declines. Among the suspected causes are pesticides, global change, ultraviolet radiation, and disease. An appendix describes the status of all 47 species of Canadian amphibians and includes photographs of most. Annotation copyrighted by Book News, Inc., Portland, OR

"The frogs, toads, salamanders, and newts that inhabit North America, numbering nearly 300 species, represent immense variation in form, habitat, distribution and ecology. This volume discusses the diversity of these animals in relation to the historical geography of the North American continent and portrays all of the formally recognized amphibian species to be found in the United States and Canada within a geographical context. Each species is presented with a color photograph, an account of its range, habitat and conservation status, and an up-to-date, full color range map that depicts its known occurrences in relation to the topography of the landscape. This volume reflects the enormous growth in interest about amphibians and increased intensity of scientific research into their biology and distribution that has occurred during the past two decades"--

In 1990 an international group of biologists, meeting to discuss rumors of declines in the number of amphibians, discovered that amphibian disappearances once thought to be a local problem were not--the problem was global. And, even more disturbing, amphibians were disappearing not just from areas settled by humans but from regions of the world once believed to be pristine. Under the mantle of the Declining Amphibian Populations Task Force, this timely book addresses three fundamental questions for the midwestern United States: are amphibians declining; if so, why; and, if so, what can be done to halt these losses? In the Midwest--defined here as Missouri, Iowa, Illinois, Indiana, Ohio, Minnesota, Wisconsin, and Michigan--there can be no doubt that the number of salamanders and frogs has declined with Euro-American settlement and the conversion to an agriculturally dominated landscape. Habitat loss and landscape fragmentation have been major factors in this decline, as have aquacultural uses of natural wetlands. Bullfrog introductions have eliminated populations of native amphibians, and collecting for the biological supply trade has reduced the number of individuals within many populations. The goal of the forty-two essays in this well-documented, well-illustrated book is to put between two covers all we know now about the status of midwestern amphibians. By doing this, the editor has created a readily accessible historical record for future studies. Organized into sections covering landscape patterns and biogeography, species status, regional and state status, diseases and toxins, conservation, and monitoring and applications, this landmark volume will serve as the foundation for amphibian conservation in the Midwest.
