Analysis of habitat specialists and generalists. Niche breadth (B) of OTUs identified in bare soil and different biocrust types. Each symbol represents an OTU. OTUs that are present along a wider range of habitats have a higher B value and are considered habitat generalists (numbered from 1-59), while OTUs with a B value < 1.5 are considered habitat specialists (numbered from 1-134). Numbers adjacent to points refer to numbers in brackets in B, C and S4. Open circles show OTUs that could not be defined as generalists or specialists (a). Circos plot showing taxonomic assignment for OTUs identified as generalists (b) and specialists in cyanobacteria-, chlorolichen-, and moss-dominated biocrusts (c). Specialists in bare soil are shown in Supplementary Figure S4. Numbers outside of the circles indicate the number of OTUs
