river ecosystems
Stream-based life systems
River ecosystems are the interconnected communities of organisms—fish, insects, plants, microbes—and their physical environment within flowing freshwater systems.
The term encompasses not just the water itself but the riverbed, banks, and floodplains where aquatic and terrestrial life interact.
Dams disrupt river ecosystems by blocking fish migration and altering sediment flow.
Ecologists study river ecosystems to understand nutrient cycling, biodiversity, and the effects of pollution or development on water quality.
