Anotace:
Species of all types are disappearing around the globe, but no group may be more threatened than amphibians. One recent analysis found that 43 percent of amphibian species are on the decline and nearly a third are officially threatened. Scientists have also counted 168 species that have gone extinct in the wild, and more than half of those extinctions have occurred in the last few decades.
One big factor has been Batrachochytrium dendrobatidis, a fungal disease also known as chytrid that was virtually unknown two decades ago. Since its discovery, scientists have witnessed mass die-offs of amphibians, especially frogs, around the world, sometimes happening overnight.
