Florida Scientists Develop DNA Test for Invasive Snakes

Scientists at the University of Florida have unveiled a groundbreaking DNA-based environmental monitoring tool aimed at enhancing Florida's defenses against invasive species. This tetraplex digital PCR assay enables rapid and precise identification of four invasive snake species—Burmese pythons, northern African pythons, boa constrictors, and rainbow boas—from environmental DNA (eDNA) in water or soil samples. Lead researcher Melissa Miller emphasizes that early detection and removal of nonnative species can significantly reduce the costs associated with containment and long-term management. The method, which has been published in the journal Ecology and Evolution, is particularly effective for detecting cryptic species that are typically hard to spot in high densities. With over 500 nonnative species in Florida, including many reptiles, this innovative tool is expected to play a crucial role in protecting the state's ecosystems.
