Genetic material from the environment offers a new way to track biodiversity
In short: Researchers reviewing the use of environmental DNA (eDNA) found that collecting genetic material from soil, sediment, or water provides a non-invasive way to monitor species. This method allows scientists to detect everything from single species to entire ecosystems without needing to physically see or capture the organisms.
By analyzing DNA found in environmental samples without obvious biological sources, scientists can identify both extinct and living plants and animals. This review highlights how eDNA overcomes the limitations of traditional visual surveys, such as the difficulty of spotting cryptic species or juveniles. However, the field is still evolving from single-species detection toward complex metagenomic ecosystem surveys.
Why it matters: Detecting DNA in the environment could revolutionize how we track Earth's changing biodiversity.
