Аннотация: Upland forest ecosystems are recognized as net sinks for atmospheric methane (CH4), oneof the most impactful greenhouse gases. Biological methane uptake in these ecosystems occurs dueto the activity of aerobic methanotrophic bacteria. Russia hosts one-ﬁfth of the global forest area, with the most extensive forest landscapes located in West Siberia. Here, we report seasonal CH4 ﬂux measurements conducted in 2018 in three types of stands in West Siberian middle taiga–Siberian pine, Aspen, and mixed forests. High rates of methane uptake of up to 0.184 mgCH4/(h*m^2) were measured by a static chamber method, with an estimated total growing season consumption of 4.5 +/ 0.5 kgCH4/ha. Forest type had little to no effect on methane ﬂuxes within each season. Soil methane oxidation rate ranged from 0 to 8.1 ngCH4/gDW/h and was negatively related to water-ﬁlled pore space. The microbial soil communities were dominated by the Alpha- and Gammaproteobacteria, Acidobacteriota and Actinobacteriota. The major group of 16S rRNA gene reads from methanotrophs belonged to uncultivated Beijerinckiaceae bacteria. Molecular identiﬁcation of methanotrophs based on retrieval of the pmoA gene conﬁrmed that Upland Soil Cluster Alpha was the major bacterial group responsible for CH4 oxidation.
