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 amphibiansElectronic books.Amphibian declines.Extinct amphibians.597.8/1788Collins James P140799Crump Martha L625274MiAaPQMiAaPQMiAaPQBOOK9910455035703321Extinction in our times2026814UNINA
