Rapid Responses of Greenhouse Gas Emissions and Microbial Communities to Carbon and Nitrogen Addition in Sediments.

ABSTRACT: Massive labile carbon and nitrogen inputs into lakes change greenhouse gas emissions. However, the rapid driving mechanism from eutrophic and swampy lakes is not fully understood and is usually contradictory. Thus, we launched a short-term and anaerobic incubation experiment to explore the response of greenhouse gas emissions and microbial communities to glucose and nitrate nitrogen (NO₃^--N) inputs. Glucose addition significantly increased CH₄ and CO₂ emissions and decreased N₂O emissions, but there were no significant differences. NO₃^--N addition significantly promoted N₂O emissions but reduced CH₄ accumulative amounts, similar to the results of the Tax4Fun prediction. Bacterial relative abu
