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 606 $aAmphibian declines 606 $aExtinct amphibians 608 $aElectronic books. 615 0$aAmphibian declines. 615 0$aExtinct amphibians. 676 $a597.8/1788 700 $aCollins$b James P$0140799 701 $aCrump$b Martha L$0625274 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910455035703321 996 $aExtinction in our times$92026814 997 $aUNINA
