A new paper published in the journal Proceedings of the Royal Society B used environmental DNA (eDNA) metabarcoding to analyze fish and zooplankton communities.
used environmental DNA metabarcoding to analyze fish and zooplankton communities., or freshwater connectivity, can transport eDNA. This highlights the potential of eDNA to provide a comprehensive view of freshwater biodiversity.
Aquatic ecosystems are connected by waterways, which allow fish, plants, and other organisms to move from one place to another. This connectivity is important for the resilience of aquatic populations, but it can also make it difficult to track the DNA of these organisms.at Queen Mary University of London, looked at three lake networks containing 21 lakes in Canada's Boreal Forest at IISD Experimental Lakes Area.
The findings have implications for the use of eDNA to monitor biodiversity in freshwater ecosystems. eDNA is a promising tool for biodiversity monitoring, but data must be interpreted in light of connectivity in the landscape. "eDNA can be used to detect the presence of species that are not easily monitored using conventional methods, including
