Nitrogen addition decreases methane uptake caused by methanotroph and methanogen imbalances in a Moso bamboo forest.

ABSTRACT: Forest soils play an important role in controlling global warming by reducing atmospheric methane (CH₄) concentrations. However, little attention has been paid to how nitrogen (N) deposition may alter microorganism communities that are related to the CH₄ cycle or CH₄ oxidation in subtropical forest soils. We investigated the effects of N addition (0, 30, 60, or 90 kg N ha^-1 yr^-1) on soil CH₄ flux and methanotroph and methanogen abundance, diversity, and community structure in a Moso bamboo (Phyllostachys edulis) forest in subtropical China. N addition significantly increased methanogen abundance but reduced both methanotroph and methanogen diversity. Methanotroph and methanogen community structures under the N deposition tre
