Even more amphibians are endangered than we thought

Due to a lack of data on many amphibian species, only about 44% of amphibians have up-to-date assessments on their risk of extinction, compared to nearly 100% of both birds and mammals. Now, researchers reporting May 6 in Current Biology have used known ecological, geographical, and evolutionary attributes of these data-deficient species to model their extinction risk — and their assessment suggests that at least 1,000 more species are threatened than was previously believed.
