The importance of microbial activity to ecosystem function in aquatic ecosystems is well
established, but microbial diversity has been less frequently addressed. This review and …

Eutrophication caused by phosphorus (P) leads to water quality problems in aquatic
systems, particularly freshwaters, worldwide. Processing of nutrients in shallow habitats …

Hydrologic connections can link hillslopes to channel networks, streams to lakes, subsurface
to surface, land to atmosphere, terrestrial to aquatic, and upstream to downstream. These …

Increased loading of nitrogen (N) and phosphorus (P) from agricultural and urban
intensification has led to severe degradation of inland and coastal waters. Lakes, reservoirs …

Concentrations of phosphorus and nitrogen in surface waters are being regulated in the
United States and European Union. Human activity has raised the concentrations of these …

Anthropogenic addition of bioavailable nitrogen to the biosphere is increasing, and
terrestrial ecosystems are becoming increasingly nitrogen-saturated, causing more …

Knowledge of headwater influences on the water‐quality and flow conditions of downstream
waters is essential to water‐resource management at all governmental levels; this includes …

Over the past 3 decades, nutrient spiraling has become a unifying paradigm for stream
biogeochemical research. This paper presents (1) a quantitative synthesis of the nutrient …

Eutrophication has threatened water resources worldwide, yet mechanistic understanding
on controls of nutrient export remains elusive. This work tests the shallow and deep …

Increased nitrogen (N) loading to lotic ecosystems may cause fundamental changes in the
ability of streams and rivers to retain or remove N due to the potential for N saturation. Lotic …
