Diverse Ammonia-Oxidizing Archaea Dominate Subsurface Nitrifying Communities in Semi-Arid Floodplains Ammonia oxidation may be driven by archaea rather than bacteria within the riparian subsurface Nitrification is a critical branch of the subsurface N cycle within semi-arid floodplain environments, but the underlying microbial communities have not been thoroughly characterized to date. Both AOA and AOB use … Continue reading Diverse Ammonia-Oxidizing Archaea Dominate Subsurface Nitrifying Communities in Semi-Arid Floodplains
