From: Littoral lichens as a novel source of potentially bioactive Actinobacteria

Clustering analysis (unweighted Unifrac distances) of 16S rRNA sequence from isolates affiliated to phylum Actinobacteria observed for the marine/littoral lichens Lichina confinis, L. pygmaea and Roccella fuciformis and the terrestrial lichen Collema auriforme.
The accompanying heatmap shows the number of OTU observed from each actinobacterial family. Sample codes are described in Table 1.
