Responses of Methanogenic and Methanotrophic Communities to Elevated Atmospheric CO₂ and Temperature in a Paddy Field.

ABSTRACT: Although climate change is predicted to affect methane (CH₄) emissions in paddy soil, the dynamics of methanogens and methanotrophs in paddy fields under climate change have not yet been fully investigated. To address this issue, a multifactor climate change experiment was conducted in a Chinese paddy field using the following experimental treatments: (1) enrichment of atmospheric CO₂ concentrations (500 ppm, CE), (2) canopy air warming (2°C above the ambient, WA), (3) combined CO₂ enrichment and warming (CW), and (4) ambient conditions (CK). We analyzed the abundance of methanogens and methanotrophs, community structures, CH₄ production and oxidation potentials, in situ CH₄ emissions using real-time PCR, T-RFLP, and clone libra
