AMBIO: A Journal of the Human Environment, 2002 Anthropogenic changes to the global N cycle are important in part because added N alters the composition, productivity, and other properties of many natural ecosystems substantially. Why does added N have such a large impact? Why is N in short supply in so many natural ecosystems?

Elastic Scattering of Nitrogen by Nitrogen
Physical Review, 1956The differential cross section for the elastic scattering of nitrogen from nitrogen was measured for incident nitrogen laboratory energies of 15.0, 17.7, 19.2, and 21.7 Mev and laboratory angles from 15\ifmmode^\circ\else\textdegree\fi{} to 55\ifmmode^\circ\else\textdegree\fi{}.

Nitrogen assimilation and nitrogen control in cyanobacteria
Biochemical Society Transactions, 2005Nitrogen sources commonly used by cyanobacteria include ammonium, nitrate, nitrite, urea and atmospheric N2, and some cyanobacteria can also assimilate arginine or glutamine. ABC (ATP-binding cassette)-type permeases are involved in the uptake of nitrate/nitrite, urea and most amino acids, whereas secondary transporters take up ammonium and, in some ...
