Amphibian Declines
Documents in comprehensive detail a major environmental crisis: rapidly declining amphibian populations and the disturbing developmental problems that are increasingly prevalent within many amphibian species.
Extinction in Our Times
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 in Decline
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
Status of Conservation and Decline of Amphibians
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.
Extinction in Our Times
Since the 1990s there has been an extraordinary decline and extinction of amphibian populations worldwide. 'Extinction in Our Times' unravels the mystery of amphibian biodiversity loss by exploring possible causes such as commercial exploitation, competition and predation by exotic species, habitat loss and climate change.
Amphibian Conservation
Amphibian Conservation is the fourth in the series of Synopses of Conservation Evidence, linked to the online resource www.ConservationEvidence.com. This synopsis is part of the Conservation Evidence project and provides a useful resource for conservationists. It forms part of a series designed to promote a more evidence-based approach to biodiversity conservation. Others in the series include bee, bird, farmland and bat conservation and many others are in preparation. Approximately 32% of the 7,164+ amphibian species are currently threatened with extinction and at least 43% of species are declining. Despite this, until recently amphibians and their conservation had received little attention...
Amphibian Declines
Excerpt from Amphibian Declines: An Issue Overview Amphibian Declines Amphibians, a class of vertebrates that includes frogs, salamanders, and caecilians, are amazing. As a group, they have been on this planet long before and ever since the dinosaurs. Various amphibian species have adapted to live in wetlands, forests, deserts, savannas, agricultural landscapes, and cities. Yet all of a sudden, many amphibian populations are declining around the world. Ranges of many species have been dramatically reduced and species extinctions have occurred rapidly.

Multiple Stressor Effects in Relation to Declining Amphibian Populations
For well over a decade, scientists have been trying to pinpoint the environmental cause for declining populations of amphibians in many habitats across the globe. Here, scientists and resource management professionals from a range of disciplines discuss standardized amphibian toxicity tests and meth
Status of Decline and Conservation of Amphibians of the Middle East
Amphibians by virtue of their thin, moist, permeable skins are poorly protected from harsh environments and are especially susceptible to chemical changes, desiccation, and alteration of their habitat. Accordingly, it is not surprising that they manifest exceptionally high rates of extinction and suffer more severe declines than do most other taxa in an environment undergoing unprecedented anthropogenic change. They are especially important to study as they serve as an early-warning system portending changes that are beginning to engulf more resistant species, including our own. The current volume covers the 14 countries of the Middle East, each written by a specialist, and is part of the Amphibian Biology series.
Addressing Amphibian Decline Through the Amphibian Conservation Action Plan
The amphibian decline phenomenon now involves in excess of a third of the roughly 6000 species of amphibians on the planet. The problems that drive the declines are diverse with no end in sight. The Amphibian Conservation Action Plan (ACAP) aims to stem amphibian decline through four recommended actions by researchers and conservation biologists: (1) Expand scientific understanding of amphibian declines and extinctions; (2) continue to document amphibian diversity and ecology and how they are changing; (3) develop and implement long-term conservation programs; (4) prepare emergency response actions for eminent crises. This Dissertation focused on two of those recommendations: expanding scien...
