Nitrogen is a requisite and highly demanded element for living organisms on Earth.
However, increasing human activities have greatly altered the global nitrogen cycle …

Nitrogen (N) pollution is a major threat to river ecosystems worldwide. Elucidating the
community structure of N-cycling microorganisms in rivers is essential to understanding how …

Nitrous oxide (N2O), a potent greenhouse gas, is produced in rivers through a series of
microbial metabolic pathways. However, the microbial source of N2O production and the …

As a potent atmospheric greenhouse gas and a major source of ozone depletion, nitrous
oxide (N 2 O) emission has been given increasing attention in aquatic systems, particularly …

Rivers are important sites for nitrogen (N) cycling processes. N removal is thought to occur
predominantly in the benthic zone and the role of the water column is frequently neglected …

The coupling removal of acid volatile sulfide (AVS), ferrous iron, and ammonia nitrogen has
been applied for black-odorous sediment remediation. In this study, calcium nitrate with …

Microorganism‐mediated nitrogen (N) cycling and dynamics are important functions of
ecosystems, but such information is limited for high‐elevation rivers. This study analyzed the …

Increasing attention has been paid to anaerobic ammonium oxidation (anammox) in river
ecosystems due to their special role in the global nitrogen cycle from land to the ocean. This …

Bacteria specialized in anaerobic ammonium oxidation (anammox) are widespread in many
anoxic habitats and form an important functional guild in the global nitrogen cycle by …

Estuarine systems are important sites of eliminating reactive nitrogen (N) delivered from land
to sea. Numerous studies have focused on N cycling in estuarine sediment. However, the N …
