  abstract = {{M}ethane-cycling is becoming more important in high-latitude ecosystems as global warming makes permafrost organic carbon increasingly available. {W}e explored 387 samples from three high-latitudes regions ({S}iberia, {A}laska and {P}atagonia) focusing on mineral/organic soils (wetlands, peatlands, forest), lake/pond sediment and water. {P}hysicochemical, climatic and geographic variables were integrated with 16{S} r{DNA} amplicon sequences to determine the structure of the overall microbial communities and of specific methanogenic and methanotrophic guilds. {P}hysicochemistry (especially p{H}) explained the largest proportion of variation in guild composition, confirming species sorting (i.e., environmental filtering) as a key mechanism in microbial assembly. {G}eographic distance impacted more strongly beta diversity for (i) methanogens and methanotrophs than the overall prokaryotes and, (ii) the sediment habitat, suggesting that dispersal limitation contributed to shape the communities of methane-cycling microorganisms. {B}ioindicator taxa characterising different ecological niches (i.e., specific combinations of geographic, climatic and physicochemical variables) were identified, highlighting the importance of {M}ethanoregula as generalist methanogens. {M}ethylocystis and {M}ethylocapsa were key methanotrophs in low p{H} niches while {M}ethylobacter and {M}ethylomonadaceae in neutral environments. {T}his work gives insight into the present and projected distribution of methane-cycling microbes at high latitudes under climate change predictions, which is crucial for constraining their impact on greenhouse gas budgets.},
