Expedition in Bolivia’s Madidi National Park Discovers New Frog Species | WCS
20 August 2015
WCS scientists on a multi-year expedition through Bolivia‘s Madidi National Park have likely discovered a new species of robber frog. They were tipped off by the distinctive orange coloring on its inner thighs and will be working over the next few months to confirm the discovery.
From Wildlife Extra:
The frog was found during the first leg of an 18-month long expedition called Identidad Madidi to chronicle the staggering wildlife living in what is believed to be the world’s most biodiverse park.
James Aparicio, a professional herpetologists from the Bolivian Faunal Collection, said, “Robber frogs are small to medium-sized frogs distributed in the Andes and Amazon region and to date there are 23 known species. As soon as we saw these frogs’ distinctive orange inner thighs, it aroused our suspicions about a possible new species, especially because this habitat has never really been studied in detail before Identidad Madidi.”
Identidad Madidi is a multi-institutional effort to describe still unknown species and to showcase the wonders of Bolivia’s extraordinary natural heritage at home and abroad. The expedition officially began on June 5th, 2015 and will eventually visit 14 sites lasting for 18 months as a team of Bolivian scientists works to expand existing knowledge on Madidi’s birds, mammals, reptiles, amphibians, and fish along an altitudinal pathway descending more than 5,000 meters (more than 16,000 feet) from the mountains of the high Andes into the tropical Amazonian forests and grasslands of northern Bolivia.
Participating institutions include the Ministry of the Environment and Water, the Bolivian National Park Service, the Vice Ministry of Science and Technology, Madidi National Park, the Bolivian Biodiversity Network, WCS, the Institute of Ecology, Bolivian National Herbarium, Bolivian Faunal Collection and Armonia with funding from the Gordon and Betty Moore Foundation and WCS.
Teresa Chávez, Director of the Bolivian Biodiversity and Protected Areas Directorate expressed her satisfaction with the scientific results of the Identidad Madidi expedition: “The description of a new species of robber frog (Oreobates) for science is important news for the country as it confirms the extraordinary biodiversity of Madidi National Park and demonstrates the importance of scientific research in protected areas.”
