A subset of the methane flux and ancillary data is additionally available on PANGAEA (https://doi.org/10.1594/PANGAEA.953119).Atmospheric methane (CH<inf>4</inf>) uptake by arctic soils is widespread in dry tundra ecosystems. However, the environmental controls regulating CH<inf>4</inf> uptake are poorly understood, particularly such as soil nutrient availability or microbial community composition. Here, we analyzed the relative abundance and community structure of functional gene markers associated with CH<inf>4</inf> and mineral nitrogen (N) cycling in two contrasting tundra types in the Western Canadian Arctic using a targeted metagenomics approach. Microbial data were compared to soil properties, macro- and micronutrient concentrations, and CH<inf>4</inf> fluxes during an entire growing season (May–August). We find that soil pH was the most important control on gene distribution between the studied microsites. Methanotrophs associated with the upland soil cluster α (USCα) dominated in polygonal tundra (low pH), while USCγ dominated in upland tundra (high pH). Methane uptake rates ranged from −15 to −27 μg CH<inf>4</inf>–C m<sup>−2</sup> h<sup>−1</sup> (growing season mean) and increased with higher relative abundances of USCα and USCγ. Although CH<inf>4</inf> uptake rates were similar between microsites, our microbial data indicate different mechanisms to cope with N limitation in these nutrient-limited tundra environments: upland tundra was characterized by genes involved in denitrification and N retention, while polygonal tundra contained genes associated with biological N fixation. Our study highlights the need for an integrated view on interactions between CH<inf>4</inf> oxidation and N availability for methanotrophs in arctic tundra soils.We received financial support from the Research Council of Finland project MUFFIN (no. 332196, grant to C·V.), the project MOMENT (no. 03F0931A) funded by the German Federal Ministry of Education and Research (BMBF), the Canada Research Chair (CRC-2018-00259) and the NSERC Discovery Grants program (DGPIN-2018-05743, both awarded to O·S.), the European Research Council Starting Grant COLDSPOT (no. 101163177, grant to C·V.), the Canada Foundation for Innovation project Changing Arctic Network (CANet, grant no. 33661), the flagship program of the Atmosphere and Climate Competence Center (ACCC, grant no. 337550), the Research Council of Finland projects PANDA (no. 317054) and Thaw-N (no. 349503, both awarded to M.E.M), and project NitroBiome (no. 342362, grant to H.M.P·S.), as well as the Global Water Futures project Northern Water Futures, the Polar Continental Shelf Program (608–20, 602–21), ArcticNet – a Network of Centres of Excellence Canada (grant no.
