Oxygenation, life, and the planetary system during Earth's middle history: An overview
The long history of life on Earth has unfolded as a cause-and-effect relationship with the
evolving amount of oxygen (O2) in the oceans and atmosphere. Oxygen deficiency …

DNRA: a short-circuit in biological N-cycling to conserve nitrogen in terrestrial ecosystems
This paper reviews dissimilatory nitrate reduction to ammonium (DNRA) in soils-a newly
appreciated pathway of nitrogen (N) cycling in the terrestrial ecosystems. The reduction of …

The biogeochemistry of ferruginous lakes and past ferruginous oceans
Anoxic and iron-rich (ferruginous) conditions prevailed in the ocean under the low-oxygen
atmosphere that occurred through most of the Archean Eon. While euxinic conditions (ie …

Identifying oxygen minimum zone-type biogeochemical cycling in Earth history using inorganic geochemical proxies
F Scholz - Earth-Science Reviews, 2018 - Elsevier
Because of anthropogenic global warming, the world ocean is currently losing oxygen. This
trend called ocean deoxygenation is particularly pronounced in low-latitude upwelling …
