CrumpOxford ;New York Oxford University Press20091 online resource (296 p.)Description based upon print version of record.0-19-531694-0 Includes bibliographical references and indexes.Declining amphibian populations and the biodiversity crisis -- Rallying around the issue of amphibian declines -- Challenges, correlates, and hypotheses -- Introduction species, commerce, and land use change -- Contaminants, global change, and emerging infectious diseases -- Unraveling the mystery -- Amphibian chytrid fungus as a cause of declines and extinctions -- New approaches to doing science and conversation -- Science policy and reacting to a challenge -- Leaping between mysteries.For over 350 million years, thousands of species of amphibians have lived on earth, but since the 1990's 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 NevadaAmphibian declinesExtinct amphibiansAmphibian declines.Extinct amphibians.597.8/1788Collins James P140799Crump Martha L625274MiAaPQMiAaPQMiAaPQBOOK9910778074403321Extinction in our times3730646UNINA
