文摘

Relative to reference streams, constructed-stream litterfall was depressed. Leaf breakdown was slower in most constructed streams, but not universally. Macroinvertebrate-mediated and microbial + physicochemical processing was inhibited. Temperature appeared to exert strongest overriding control on leaf breakdown. Riparian plantings can moderate stream temperatures and provide organic matter.
