Network graph highlighting shared OTUs between different anaerobic fungal communities in different animal hosts. The graph is colour-coded by animal host phylogeny (family). Circular nodes indicate animal data sets, whereas smaller square, grey nodes represent individual OTUs. Data sets with a higher proportion of shared OTUs are pulled to the middle, whereas data sets with a high proportion of unique OTUs remain on the periphery. The distance between any two data sets is a function of the number of shared OTUs between the two. Figure supplied by Audra Liggenstoffer.
