Summary:
- The article discusses the use of environmental DNA (eDNA) analysis to study the biodiversity of marine ecosystems, particularly in the deep sea.
- eDNA analysis involves collecting water samples and extracting genetic material from the environment, which can provide insights into the presence and abundance of various marine species without directly observing them.
- The study highlights the potential of eDNA as a non-invasive and cost-effective tool for monitoring and assessing the health of deep-sea ecosystems, which are often difficult to access and study using traditional methods.
