Relationships between environmental factors and Streptomyces phylogenetic (UniFrac distance) and taxonomic (Bray-Curtis dissimilarity) values^a

Analysis type	Sequence inclusion	Correlation (R2 value) withb:
		Latitude	Soil pH	Temp	SOM	PPT
UniFrac	Weighted	0.52**	0.35	0.50**	0.26	0.28
	Unweighted	0.48***	0.41*	0.44**	0.32	0.34
Bray-Curtis	Weighted	0.46***	0.40*	0.44**	0.21	0.33
	Unweighted	0.46***	0.44**	0.44**	0.25	0.31

^aAnalyzed by using the adonis program (permutational multivariate analysis of variance) within the R package.

^bBold values indicate statistically significant correlations (*, P < 0.05; **, P < 0.01; ***, P < 0.001). The analyses were performed by either including all rpoB sequences (weighted) or excluding duplicate sequences for each OTU (unweighted). Abbreviations: Temp, average annual temperature; SOM, soil organic matter content; PPT, annual average precipitation.
