Fig. 6

Core bacterial taxa in the hindgut of different feeding guilds of cockroaches and higher termites. The pie charts represent the average proportion of reads from core bacterial genera (red) and families (blue) relative to the entire bacterial community. The host groups used to define the respective core taxa are circumscribed with a rectangle: (a) all cockroaches except Cryptocercus punctulatus, (b) wood and litter-feeding cockroaches, and (c) wood-feeding higher termites. A core taxon was a genus present in > 70% or a family present in all members of the host groups in the respective rectangle. Numbers below the charts provide the average proportion of core taxa over the total number of taxa. For details, see Additional file 2: Table S3
