Methanogenic Community, CH 4 Production Potential and Its Determinants in the Active Layer and Permafrost Deposits on the Tibetan Plateau
Permafrost thaw could increase methane (CH 4 ) emissions, which largely depends on CH 4 production driven by methanogenic archaea. However, large-scale evidence regarding key methanogenic taxa and their relative importance to abiotic factors in mediating methanogenesis remains limited. Here, we expl...

Permafrost thaw could increase methane (CH 4 ) emissions, which largely depends on CH 4 production driven by methanogenic archaea.

Here, we explored the methanogenic community, potential CH 4 production and its determinants in the active layer and permafrost deposits based on soil samples acquired from 12 swamp meadow sites along a ∼1000 km permafrost transect on the Tibetan Plateau. Our results revealed lower CH 4 production potential, mcrA gene abundance, and richness in the permafrost layer than those in the active layer. CH 4 production potential in both soil layers was regulated by microbial and abiotic factors. Of the microbial properties, marker OTUs, rather than the abundance and diversity of methanogens, stimulated CH 4 production potential. Marker OTUs differed between the two soil layers with hydrogenotrophic Methanocellales and facultative acetoclastic Methanosarcina predominant in regulating CH 4 production potential in the permafrost and active layer, respectively.
