Deep in the weeds: Using eDNA sequencing to survey pondweed diversity
(WorldNews Environment)

Researchers have developed a protocol using environmental DNA (eDNA) to identify aquatic plant diversity, making ecological biodiversity surveys of these plant communities faster and less expensive. Their study on pondweeds -- an important bioindicator of aquatic ecosystem health -- allows researchers to overcome difficulties in monitoring and identification, and draw conclusions regarding plant diversity and water quality. eDNA is a rapidly emerging technique, but its use in aquatic habitats has been understudied. ......
