Abstract: In the present work, I studied the abundance, composition, and activity of soil microbial communities involved in the decomposition of soil organic matter (OM) in different horizons and under distinct tundra vegetation of Arctic permafrost soils. Special emphasis was given to buried topsoil caused by cryoturbation processes. The enzyme activity and their stoichiometry were also analyzed to determine the limitation of microbial carbon, nitrogen, and phosphorus. I also applied the metatranscriptomics approach to study the active microbial community in a complex view of all three domains of life (bacteria, archaea, Eukaryota). With this approach, we could better understand the potential role of microbial interactions (e.g., bacterial predation) in the carbon and nitrogen cycles of permafrost soils.
