Aquatic habitat response to small dam removal demonstrates recovery in three years

Ecosphere, Volume 16, Issue 6, June 2025.
Abstract Dams disrupt river networks by interrupting longitudinal transport of sediment and nutrients and obstructing the movement of aquatic organisms. Increasingly, water resource managers are looking for dam removal as a solution to restore connectivity and improve aquatic habitats, water quality, and fish passage.

Capture—Incubate—Release: An Animal‐Friendly Approach to Assess Local Aquatic Macroinvertebrate Species Diversity Through Environmental DNA Metabarcoding

Environmental DNA, Volume 7, Issue 3, May–June 2025.
We assessed whether we can combine the advantages of both bulk and eDNA metabarcoding, that is, obtaining a local signal and being minimally invasive, to improve local invertebrate detections in streams using water samples. We quantified eDNA release over time after a short incubation in water for single species using qPCR and for bulk samples using ...
