Table 2. Levels of phylogenetic clustering of the lichen associated bacterial communities as measured by the Nearest Taxon Index (NTI) and the Net Relatedness Index (NRI).

Lichen species	N ∘ taxa	NRI	runs > null	NTI	runs > null

L. pygmaea	281	3.49**	998	1.68*	951
X. aureola	224	3.13**	997	2.15*	978
Inland Austrian lichens

L. fuscovirens	205	1.05	859	1.61	938

Notes.

The values of each metric for the coastal or inland lichens are presented together with the number of runs where the observed NRI/NTI values were greater than those of the null model.
