From: The gut of the finch: uniqueness of the gut microbiome of the Galápagos vampire finch
Non-metric multidimensional scaling (NMDS) ordination of gut microbial communities of Darwin’s finches according to a species, b island, c diet, and d season for all finches in the sample set. Taxonomic (OTU) clustering is at 97% identity and abundance weighted by taking the fourth-root of the OTU relative abundance in each finch. Ellipses represent 90% confidence windows following a multivariate t-distribution. ANOSIM p values are shown for relationships, including and excluding the vampire finch species G. septentrionalis
