Australian Museum Researchers Use Insect DNA to Detect Wildlife in Namadgi National Park
Researchers from the Australian Museum, including Tim Cutajar and Dr. Stephanie Pulsford, conducted a study in Namadgi National Park in the Australian Capital Territory in late 2020. They employed invertebrate-derived DNA (iDNA) techniques, originally developed for detecting frogs via blood-sucking flies, to survey vertebrate species. Unexpectedly, the method identified DNA from a cat, a dingo, and a Rosenberg's monitor lizard in the cool, dry forest environment. This finding suggests iDNA could be valuable for monitoring threatened species like the Rosenberg's monitor and detecting invasive predators in protected areas. The research indicates potential applications for biodiversity conservation in southern Australian forests.
