Therefore, this is the final stage of the nitrogen cycle, carried on without oxygen. The entire process of denitrification is carried out ...
WebApr 15, 2016 · The shift to lower δ 15 N values suggests locally enhanced nitrogen fixation, possibly as a consequence of increased denitrification in response to globally expanded marine anoxia. Thus, these δ 15 N bulk data are consistent with the hypothesis that intense anoxia was the immediate cause of the end-Devonian mass extinction.
