Waters flowing rapidly through artificial conduits are typically bereft of their own primary producers in the absence of light and rely on imported algae and detritus as sources of energy. These support simple bacterial and fungal communities in biofilms and largely itinerant invertebrates. Diversity, abundance and productivity are low, but filter feeders may colonise and productivity may be higher if source waters supply nutrients and organic carbon.
Artificial flowing waterbodies that carry water with variable flow regime, limited light, sometimes with high carbon and nutrients supporting opportunities aquatic detritivores and predators.
Ubiquitous in developed regions of the world, most commonly in urban landscapes and irrigation areas.

Maps are indicative of global distribution patterns are not intended to represent fine-scale patterns. The maps show areas of the world containing major (coloured red) or minor occurrences (coloured yellow) of each ecosystem functional group. See general notes on maps.
