Microbial Communities and Interactions of Nitrogen Oxides With Methanogenesis in Diverse Peatlands of the Amazon Basin.

ABSTRACT: Tropical peatlands are hotspots of methane (CH₄) production but present high variation and emission uncertainties in the Amazon region. This is because the controlling factors of methane production in tropical peats are not yet well documented. Although inhibitory effects of nitrogen oxides (NO _x ) on methanogenic activity are known from pure culture studies, the role of NO _x in the methane cycling of peatlands remains unexplored. Here, we investigated the CH₄ content, soil geochemistry and microbial communities along 1-m-soil profiles and assessed the effects of soil NO _x and nitrous oxide (N₂O) on methanogenic abundance and activity in three peatlands of the Pastaza-Marañón foreland basin. The peatland
