TL;DR: These findings provide a first mechanistic understanding of priming in permafrost soils and suggest that an increase in the availability of organic carbon or nitrogen, e.g., by increased plant productivity, can change the decomposition of SOM stored in deeper layers of permaf frost soils, with possible repercussions on the global climate.

TL;DR: Results indicate that Archaeoglobus can be a major player in hot oil reservoirs, and nitrate may act in souring control—not only by inhibiting SRP, but also by changing the overall community structure, including the stimulation of competitive nitrate reducers.

TL;DR: The study expands the knowledge on the microbial community structure in soils of Northern latitude permafrost regions, and attributes the delayed decomposition of SOM in buried soils to specific microbial taxa, and particularly to a decrease in abundance and activity of ECM fungi, and to the extent to which bacterial decomposers are able to act as their functional substitutes.

TL;DR: In this article, the microbial community structure in cryoturbated soils from nine soil profiles in the northeastern Siberian tundra using high-throughput sequencing and quantification of bacterial, archaeal and fungal marker genes.

TL;DR: In this paper, the authors compared gross rates of protein depolymerization, ammonium (N mineralization), and nitrification in seven ecosystems along a latitudinal transect in western Siberia, from tundra to steppe (54°N).
