Magnitude and Drivers of Potential Methane Oxidation and Production across the Tibetan Alpine Permafrost Region
Methane (CH4) dynamics across permafrost regions is critical in determining the magnitude and direction of permafrost carbon (C)-climate feedback. However, current studies are mainly derived from the Arctic area, with limited evidence from other permafrost regions. By combining large-scale laborator...

Methane (CH4) dynamics across permafrost regions is critical in determining the magnitude and direction of permafrost carbon (C)-climate feedback. However, current studies are mainly derived from the Arctic area, with limited evidence from other permafrost regions. By combining large-scale laboratory incubation across 51 sampling sites with machine learning techniques and bootstrap analysis, here, we determined regional patterns and dominant drivers of CH4 oxidation potential in alpine steppe and meadow (CH4 sink areas) and CH4 production potential in swamp meadow (CH4 source areas) across the Tibetan alpine permafrost region. Our results showed that both CH4 oxidation potential (in alpine steppe and meadow) and CH4 production potential (in swamp meadow) exhibited large variability across various sampling sites, with the median value being 8.7, 9.6, and 11.5 ng g(-1) dry soil h(-1), respectively.
