Relationship between the content of basic chemical elements and ecological and trophic groups of microorganisms in peat oligotrophic frozen soil

The paper analyzed the number of ecological-trophic groups of microorganisms and the elemental composition of the active, permafrost and thawed layers of a typical flat mount frozen peatlands (plateau palsa) in the Nadym-Pur interfluves, Western Siberia, with part of it affected by fire. The number of ecological-trophic groups was found to change after permafrost thaw. The study revealed a relationship between the number of microorganisms and the content of some chemical elements in the soil profile of the plateau palsa in the Nadym-Pur interfluve. A statistically significant relationship was found between the most probable number of microorganisms (CFU/g) in different peat layers and the pH, the ash content and the content of calcium, magnesium, strontium, and iron.The study was financially supported by the Russian Foundation for Basic Research within the framework of project No. 20-34-90090
