Principal coordinate analysis of bacterial community composition from Midas cichlids’ guts (colored symbols) and their natural environment (water, black symbols) measured as weighted UniFrac. Bacterial communities of the water samples are clearly differentiated from those of fish guts along PCoA1. This is confirmed by a PERMANOVA statistical test of bacterial community composition (adonis, P = 0.001). Among Midas cichlids, no apparent clustering by lake or species can be detected along PCoAs 1 and 2. Yet, PERMANOVA tests showed that bacterial community composition of fish guts differs among lakes (P = 0.001) and also between environment types (great lakes vs. crater lakes; P = 0.003)
