A Niche breadth (B) of the specialists, common taxa, and generalists. The x-axis indicates average relative log-abundances. Each dot represents an individual amplicon sequence variant (ASV). The ASVs of generalists (B > 78), common taxa (22 ≤ B ≤ 78), and specialists (B < 22) are indicated in black, red, and orange, respectively. B Relative abundance of generalists, common taxa, and specialists in the total bacterial community composition
