Analysis of similarity (ANOSIM) of the structure and function of the bacterial communities based on the Bray–Curtis metric

Group	Community structure		Community function
	R	p	R	p
PS vs. VS	−0.1146	0.847	0.0104	0.333
PW vs. VW	0.2188	0.105	0.0313	0.298
PG vs. VG	−0.1667	0.982	−0.125	0.926
PC vs. VC	0.0625	0.227	0.1458	0.199
PM vs. VM	0.9896	0.034	0.9583	0.032

Permutation N = 999; R is assessed by permuting the grouping vector to obtain the empirical distribution of R under the null model; a p-value less than 0.05 means significant
