Luo, Y. W. et al. Database of Diazotrophs in Global Ocean: Abundance, Biomass, and Nitrogen Fixation Rates.
A modelling study shows how a small shift in the nitrate-to-phosphate uptake ratio of phytoplankton has a large effect on calculated nitrogen fixation rates.
Bonnet, S. et al. Contrasted geographical distribution of N2 fixation rates and nifH phylotypes in the Coral and Solomon Seas (southwestern Pacific) during austral winter conditions.
In contrast, modern-day temperatures seem to constrain N(2) fixation rates and N(2 -fixing species from mature forests in the high latitudes.
The examination of the fixation rates and speed of adaptation discloses the dichotomy exhibited by percolation maps and fractal landscapes.
The nitrogen fixation rates by two different types of electrical discharges, namely lightning and coronae, were studied over a wide range in CO2 and N2 mixing ratios.
This study was designed to induce various concentrations of P and Fe in the nodule and to measure the resultant nitrogen accumulation and nitrogen fixation rates.
Adequate supplies of phosphorus (P) and iron (Fe) to legumes have been shown to be crucial in obtaining high nitrogen fixation rates and growth.
However, little attention has been given to documenting the response of nitrogen fixation rates resulting from concentrations of P and Fe that actually exist in nodules.
13C CH4 oxidation rates were calculated in a similar fashion as the 15N N2 fixation rates.
The N fixation rates are given by Yan et al. (2003).
