Amphibian Populations Declining More Rapidly Than Previously Reported
The number of frogs, toads and salamanders in the US could be falling at an even more severe and widespread rate than previously believed, and even amphibian populations thought to be stable are actually on the decline, according to new research for the US Geological Survey (USGS).
The study, which was published earlier this week in the journal PLOS ONE, is believed to be the first-ever estimate of how quickly amphibians across the country are disappearing from their habitats. In the study, USGS scientists and their colleagues found dropping numbers of amphibians in populations everywhere, from the swamps of the southeast to high mountain ranges like the Rockies and the Sierras.
