TL;DR: Nutrient enrichment increased microbial activity, the proportion of leaf carbon channelled through the microbial compartment and the decomposition rate of leaf litter, suggesting a primary role of fungi in leaf decomposition.

TL;DR: The results indicate that the chemistry of the water can be an important regulator of leaf breakdown in streams by affecting the activity of decomposer fungi.

TL;DR: Terrestrial carbon is rapidly lost from stream ecosystems as a result of nutrient enrichment, and this magnitude of terrestrial C loss can potentially exceed predicted algal C gains with nutrient enrichment across large parts of river networks, diminishing associated ecosystem services.

TL;DR: Stepwise regression found that flow regime, snail biomass, snail and total invertebrate richness, and metal and nutrient content were likely factors affecting litter breakdown rates in these streams.

TL;DR: The relative contributions of fungi and bacteria to carbon flow from submerged decaying plant litter at different levels of inorganic nutrients (N and P) were studied in this paper, where the authors estimated leaf mass loss, fungal and bacterial biomass and production, and microbial respiration and constructed partial carbon budgets.
