TABLE 4.

Variance partitioning of putative methanogens by compartment based on Bray–Curtis distance between communities considering each compartment (phyllosphere, rhizosphere, and bulk peat) separately.

	Phyllosphere	Rhizosphere	Bulk Peat
No. observations	46	64	41
Plant total R2	–0.01	0.36*	0.24*
Unique R2	–0.05	0.15*	0.028
Habitat total R2	–0.02	0.22*	0.25*
Unique R2	–0.01	0.07*	0.04
All	–0.02	0.37*	0.28*

Unique R² is only the variance explained by a factor that does not overlap with any other factor. All R² values are adjusted for multiple tests. Starred values are significant at p < 0.001 based on redundancy analysis. Phyllosphere overall model was not significant (p = 0.615), plant unique R² not significant (p = 0.125) and habitat unique R² significant at p = 0.039.
