Shannon diversity index of the bacterial communities associated with H. stipulacea along a depth gradient.

Depth (m)	Shannon diversity (H′)
	Aboveground	Belowground
4	5.04 ± 0.15	5.30 ± 0.46
9	4.37 ± 0.25	4.85 ± 0.55
18	4.98 ± 0.33	5.05 ± 0.37
28	4.67 ± 0.07	4.51 ± 0.56

Values represent the means (±SD) of two replicates per depth. The normalized dataset was used.
