A recent study conducted by researchers at the University of California, Davis has revealed the widespread presence of environmental DNA (eDNA) throughout the world’s oceans. eDNA is genetic material that is shed by living organisms and can be used to identify species in marine and freshwater systems. The study provides new insights into the ways in which eDNA can be used to monitor marine ecosystems and improve conservation efforts. By tracking eDNA, researchers can gain a better understanding of the diversity and abundance of species in different regions. This information can then be used to inform conservation strategies and help protect and sustain marine ecosystems.
