Moss-cyanobacteria associations as biogenic sources of nitrogen in boreal forest ecosystems
The biological fixation of atmospheric nitrogen (N) is a major pathway for available N entering ecosystems. In N-limited boreal forests, a significant amount of N2 is fixed by cyanobacteria living in association with mosses, contributing up to 50 % to ...

UCYN-A/haptophyte symbioses dominate N2 fixation in the Southern California Current System. [PDF]
The availability of fixed nitrogen (N) is an important factor limiting biological productivity in the oceans. In coastal waters, high dissolved inorganic N concentrations were historically thought to inhibit dinitrogen (N2) fixation, however, recent N2 ...

Systemic regulation of soybean nodulation and nitrogen fixation by nitrogen via isoflavones
Nitrogen (N) inhibits soybean (Glycine max L.) nodulation and N2 fixation. Isoflavones secreted by soybean roots can stimulate signal transduction for symbiotic nodules, thus playing a key role in root nodule development and N2 fixation. The relationship

The conundrum of marine N2 fixation [PDF]
Over the last 30 years, immense progress has been made in understanding the global significance of marine nitrogen (N2) fixation. Development of enzymological, isotopic and molecular techniques for identifying N2 fixers and quantifying N2 fixation rates, as well as more frequent and extensive field campaigns have fuelled such progress.

Free atmospheric CO2 enrichment increased above ground biomass but did not affect symbiotic N2-fixation and soil carbon dynamics in a mixed deciduous stand in Wales [PDF]
Through increases in net primary production (NPP), elevated CO2 is hypothesizes to increase the amount of plant litter entering the soil. The fate of this extra carbon on the forest floor or in mineral soil is currently not clear.

Symbioses between cyanobacterial communities and feather mosses in boreal forests and consequences for dinitrogen fixation [PDF]
Feather moss-cyanobacteria associations, although still poorly understood, are recognised as essential for the regulation of nitrogen (N) input into N-limited ecosystems such as boreal forests due to their ability to carry out N2-fixation.

Electrochemical N2 reduction reaction (NRR) has emerged as the most effective alternative to the conventional Haber-Bosch process for N2 fixation. Although NRR is only used in the synthesis of NH3, researchers have recently exploited it in Metal-N2 ...

Evaluating the balance between vertical diffusive nitrate supply and nitrogen fixation with reference to nitrate uptake in the eastern subtropical North Atlantic Ocean [PDF]
The balance between N2 fixation and diffusive NO3− supply is a key determinant for assessing the importance of both processes for new production in subtropical waters.

Effects of changed levels of dissolved O2 and CO2 on marine primary producers are of general concern with respect to ecological effects of ongoing ocean deoxygenation and acidification as well as upwelled seawaters.

Benthic nitrogen fixation in Zostera marina meadows in an upwelling-influenced coastal lagoon
Dinitrogen (N2) fixation rates were determined in the phyllosphere and in sediments with and without the presence of eelgrass (Zostera marina) in San Quintín Bay, an upwelling-influenced coastal lagoon in the NE Pacific.
