Discussion
Most studies conducted in the past decade have focused on the relation of eDNA persistence with environmental conditions, and little attention has been paid to the relationship between the persistence of eDNA and its cellular states and molecular structures. In the present study, we integrated the findings of previous reports on eDNA and provided new insights into the relationship between the persistence and state of eDNA. Our findings indicated significant influences of the complex interactions between eDNA states and environmental factors on eDNA persistence.
