Scientists are increasingly utilizing environmental DNA (eDNA) to efficiently detect both invasive and endangered species, transforming conservation research.
Lourdes Medrano reports for Undark.
In short:
- eDNA technology allows for the identification of species through genetic material found in environments, offering a non-invasive, cost-effective approach to conservation.
- Researchers use eDNA to monitor biodiversity, track invasive species, and support conservation efforts, amidst calls for national eDNA application strategies to streamline processes.
- The field faces challenges such as the rapid degradation of DNA and limitations in detecting certain species, but advancements in technology and methodology are continually improving its efficacy.
Key quote:
“This technology will end up being critical because it’s a more efficient way to detect invasive species, as well as rare species.”
— Andy Hubbard, program manager for the National Park Service Sonoran Desert Network
Why this matters:
eDNA represents a pivotal shift in conservation strategies, enabling rapid, early detection of invasive species and comprehensive biodiversity monitoring. eDNA technology, paired with eDNA-gathering robotics, can be a boon for programs with limited people-power as early detection can power quicker and better-informed responses to emerging threats.
