Spatiotemporal variations and environmental drivers of denitrifying anaerobic methane oxidizers in <i>Eriocheir sinensis</i> pond sediments.

ABSTRACT: Denitrifying anaerobic methane oxidation (DAMO), as a coupled carbon-nitrogen cycling process, facilitates methane oxidation while enabling inorganic nitrogen removal. Crab aquaculture pond sediments, being rich in organic matter and nitrogen, may serve as hotspots for active DAMO processes. However, the presence of DAMO-functional microorganisms in such environments remains unconfirmed. In this study, we employed quantitative real-time polymerase chain reaction (qPCR) to analyze the abundance variations of DAMO functional microorganisms in crab pond sediments across different temporal (May, September, December) and vertical (0-10 cm, 10-20 cm, 20-30 cm) scales. Combined with concurrent physicochemical parameter measurements and high-throughput sequencing, the spatiotemporal distribution p
