Bolivian Andes
Why in News?
- A scientific expedition high in the Bolivian Andes revealed 20 species new to science, including “lilliputian frog” plus four rediscovered species including the “devil-eyed frog” previously thought to be extinct.
- The expedition was led by the environmental group and the government of capital city La Paz.
- The remarkable rediscovery of species once thought extinct, especially so close to the city of La Paz, illustrates how sustainable development that embraces conservation of nature can ensure long-term protection of biodiversity.
About Discoveries
- The lilliputian frog measures only about 10 millimeters in length, making it one of the smallest amphibians in the world.
- Due to their tiny size and habit of living in tunnels beneath the thick layers of moss in the cloud forest, they were difficult to find even by tracking their frequent calls.
- Four new butterfly species were also discovered, including two species of “metalmark butterflies”, which feed on flower nectar in open areas and forest clearings.
- The devil-eyed frog, which was previously known only from a single individual observed more than 20 years ago, was found to be relatively abundant in the cloud forest.
- “Alzatea verticillata,” a small flowering tree that was previously known only from a single record in Bolivia and was found on this expedition after 127 years.
