Fig. 1. Biogeography of microbial community structure in reef-associated marine sediments.

Solid lines denote the least squares linear regression across spatial scales for taxonomic, functional, biosynthetic potential (assessed based on both operational biosynthetic units (OBUs) of ketosynthase/condensation domains and gene cluster families (GCFs)), and community metabolomes. Each point represents a pairwise comparison between community samples with distances derived from Bray-Curtis metrics for all measurements except for metabolomes, which used Euclidean distances.
