Microbial communities of sheltered soil and bare soil samples from the Qaidam Basin. (a) Relative abundance of dominated taxa in soil microbial communities according to 16S rRNA gene sequencing. Bare regolith samples 0707, 0711, and 0712 without shields have been previously investigated (36), which were collected in different areas from YX and YP samples in the northwestern Qaidam Basin. (b and c) Principal coordinate analysis (PCoA) ordination plots of all samples based on unweighted (b) and weighted (c) UniFrac.
