Short summary
Using eDNA to study fish communities in river–lake systems is a new, cost-effective method. Our study found that water eDNA might miss some fish living in the sediment. Fish communities in rivers and lakes are quite similar, showing how connected these systems are. The environment, especially temperature, influences the genetic signals found in water and sediment. This research sheds light on the effectiveness of eDNA in understanding aquatic ecosystems.
