A deadly fungus decimated populations of frogs and other amphibians around the globe in the late 20th century. Today a new, even more lethal one is on the march. Biologists are taking lessons from the previous “amphibian apocalypse” to try to hold off the next big wave of deaths and extinctions.
Frogs, salamanders and other amphibians might not stir warm thoughts, but their existence—and their decline—affects humans and other animals in critical ways. The global drop in amphibian populations has drastically affected ecosystems, lowering water quality, harming algae and water insects and destroying food webs critical for the preservation of a range of species.
