Abstract

The Arctic tundra is an appropriate location for studying the relationship among plants, bacterial communities and chemical properties of soils due to simple vegetation. 16S rRNA gene sequencing was performed to investigate bacterial community composition. Significant differences were found in soil physical and chemical properties and bacterial community structure in secondary arctic brown soils around Dryas octopetala, Luzula confusa and Bistorta vivipara in the Arctic tundra near Ny-Ålesund. Redundancy analysis showed all measured geochemical factors were significant in structuring microbiomes, with high correlation to pH and organic. The presence of vegetation could affect the physical and chemical factors in the soil, which in turn affects the bacterial community and composition in the soil.
