Wetland systems are known methane (CH 4 ) sources. However, flooded rice fields periodically drained. The paddy soils can absorb atmospheric CH during the dry seasons due to high-affinity methane-oxidizing bacteria (methanotroph). Atmospheric uptake be induced low-affinity oxidation of high-concentration in soils. Multiple interacting factors control soil ecosystems. Broader biogeographical data required refine our understanding biotic and abiotic related Thus, here, we aimed assess activity explored community composition active methanotrophs nine geographically distinct Chinese Our findings demonstrated that 1.86 parts per million by volume (ppmv) was quickly after 10,000 ppmv consumption conventional methanotrophs. ratios 16S rRNA genes (rDNA) for type II were higher than those I all acid-neutral (excluding alkaline soil) with activity. Both rRNA:rDNA abundance 13 C-labeled positively correlated Soil regulate methanotrophic High-affinity activity, as well methanotroph, negatively pH, while they nutrient availability (soil organic carbon, total nitrogen, ammonium-nitrogen). results indicate importance offer a broader perspective on This provides evidence drained serve dry-season sink. study is anticipated help determining devising greenhouse gas mitigation strategies through effective farm management fields.

Abstract The study systematically analyzes the photodegradation processes of humic in plateau lake Erhai Lake and their interactions with clay minerals. experiments simulate reactions under natural conditions, comparing changes before after reactions. reduction total organic carbon (TOC) functional groups matter products are recorded. Aromatic aliphatic compounds have a key role photodegradation. rate shows nonlinear change, presence minerals accelerates process humic. adsorption effects significantly alter photochemical behavior Under influence minerals, by increases contact photons, thereby enhancing efficiency continuous reaction continuously reduces particle size adsorbed on surface further increasing accelerating entire system.
