| Abstract: |
| Environmental DNA(eDNA) refers to the DNA of all organisms found in the environment. eDNA can be helpful in determining community or species composition information in the ecosystem by analyzing DNA fragments directly from different environmental samples using sequencing techniques. Compared to traditional biological monitoring methods based on morphological identification, eDNA has the advantages of simplicity, high effectiveness, high sensitivity, and environmental friendliness. It is an important avenue for future research in aquatic ecosystems. Here, we review the operational flow of eDNA technology, its application in aquatic ecosystems, and existing problems, as well as prospective development trends of eDNA technology. |
