Researchers from Yale-NUS College and the North Carolina Museum of Natural Sciences have discovered five new species of Southeast Asian frogs from a group of museum specimens that had long been considered to only contain two species. This research by lead author Yale-NUS College Assistant Professor of Science (Environmental Studies) Jennifer Sheridan and her co-author Dr Bryan Stuart, Research Curator of Herpetology at the North Carolina Museum of Natural Sciences, was recently published in the peer-reviewed open access journal PLOS ONE. To distinguish the five new species of frogs from the original two, they examined close to 400 frogs housed in 11 natural history museum collections around the world and sequenced five genes from close to 350 individuals.
