Similarity between the hindgut microbiota of cockroaches and higher termites, based on the weighted UniFrac metric and visualized by non-metric multidimensional scaling (NMDS). Polygons circumscribe cockroach species (squares) and termite species (circles) of the same diet groups (indicated by different colors). The wood-feeding cockroaches are Panesthia angustipennis and Salganea esakii; the wood-feeding Cryptocercus punctulatus (triangle), whose gut microbiota is dominated by eukaryotic symbionts and resembles that of lower termites, was treated as a separate group (see text). Species and color code for diet are the same as in Fig. 7
