Summary:
- Researchers have used environmental DNA (eDNA) to study the biodiversity of the Arctic Ocean, which is difficult to access and study directly.
- By analyzing water samples, they have identified a wide range of organisms, from microscopic plankton to large marine mammals, providing a comprehensive picture of the Arctic's ecosystem.
- This eDNA approach allows scientists to monitor the effects of climate change and other environmental stressors on the Arctic's delicate and rapidly changing ecosystem.
