Methane Oxidation Potential and Niche Differentiation of Aerobic Methanotrophs in Coastal Mangrove Forest Soils along a 370 Km Long Coastline in Taiwan.

ABSTRACT: Mangrove forests are key blue carbon ecosystems, but their net sink potential depends on methane oxidation in soils. In this study, DNA-based stable isotope probing was employed to decipher the changes of potentially active methanotrophic communities across five different mangrove forests along a 370 km coastline of Taiwan, with Kandelia obovata dominating the northern sites (Hsinchu and Miaoli) and Avicennia marina dominating the central and southern sites (Changhua, Tainan, and Pingtung). The results showed that the CH₄ oxidation potentials ranged from 10 to 60 nmol CH₄ g^-1 hr¹ in the mangrove forest soils. The pmoA sequencing of fresh soils revealed that unclassified Methylomonadaceae-affiliated methanotrophs, Me
