Table 1.

Functional and taxonomic additive diversity partitioning of bacterial communities across 24 tree phyllosphere samples. The percentage of alpha diversity was calculated as the amount of alpha entropy divided by the amount of total entropy across all communities. The percentage of beta diversity was calculated as 1 minus the percentage of alpha diversity

	Functional			Taxonomic
	Tier 2	Tier 3	Functional gene	Phylum	Class	Order	Family	Genus	Species
Alpha diversity (%)	100.0	99.8	97.2	99.0	99.0	99.0	98.8	98.2	95.6
Beta diversity (%)	0.0	0.2	2.8	1.0	1.0	1.0	1.2	1.8	4.4
