Analysis of similarities (ANOSIM) of bacterial community groups at different spatial scales^a

Grouping	Whole community		Abundant		Rare
	R	P value	R	P value	R	P value
Global	0.895	0.001	0.861	0.001	0.909	0.001
S-M vs S-N	0.971	0.001	0.945	0.001	0.986	0.001
S-M vs S-F	0.811	0.001	0.769	0.001	0.818	0.001
S-N vs S-F	0.946	0.001	0.929	0.001	0.938	0.001

^aThe S-N sampling transect was located about 300 m away from the water-land junction and was without vegetation; the S-M sampling transect was located about 1,000 m away from the water-land junction and was mainly covered with Scirpus mariqueter; the S-F sampling transect was located about 2,500 m away from the water-land junction and was mainly covered with Phragmites australis. All P values are significant.
