Biologist names four new frog species in Peru
An FIU biologist recently identified four new frog species near a national park in Peru.
Researchers used genetic and acoustic data to prove these frogs are distinct from known species. This work raised the total count of Oreobates frogs from twenty seven to thirty one species in the region today. The findings were published recently in the scientific journal Diversity for peer review.
Alessandro Catenazzi explained that naming organisms is the essential first step before studying their potential value. He said many species described in the past remain in European museums or collections in New York. Biologists must visit these locations to handle the original type specimens for accurate comparison.
The team compared physical traits like skin texture and color to distinguish the new specimens from relatives. They also recorded mating calls to ensure females would not be attracted to the wrong species. These audio differences are very useful for confirming the distinct identity of each new frog.
DNA sequences provided the final proof by reconstructing the evolutionary family tree for these unique animals. Specific genetic pieces were compared against many other frogs without needing to sequence entire genomes. This genetic evidence supported the decision to recognize the four frogs as completely distinct species.
