Article Summary
- The presence of an endangered Australian bird species, the Gouldian finches (Erythrura gouldiae), was detected by trace DNA from a frequented watering hole.
- It has been established that large animal and plants can leave enough trace DNA in their environment to be able to track their presence in a given location.
- Water bodies are especially good collection sites for environmental DNA (eDNA) since they are often visited by even the most elusive or reclusive species.
Why Is This Important?
- This is a non-intrusive way to document and/or monitor the populations of animal species without catching or disturbing the subject under study
