Long‐term environmental flows restore benthic invertebrate communities in a highly regulated river

open access: yesRestoration Ecology, Volume 32, Issue 5, July 2024.
The construction of dams and other in‐stream structures for human use has altered river ecosystems worldwide. Dams degrade rivers, and environmental flow releases aim to mitigate flow alterations and restore rivers downstream of dams by returning elements of the pre‐regulation flow regime, resulting in an ecosystem that resembles a more natural state ...
