Cluster dendrograms of the functional profiles of the protist and bacterial community. Community distances are based on Bray-Curtis Dissimilarities of a) all functions of the protist community (25,795 sequences), b) The category “information storage and processing” of the protist community (4527 sequences), c) all functions of the bacterial community (21,215,480 sequences), and d) the category “metabolism” of the bacterial community (10,586,058 sequences). Cd (red) = C. domesticus colonies; Cs (orange) = C. secundus colonies; Ps (green) = P. simplex colonies; Rf (blue) = R. flavipes colonies; Rg (lightblue) = R. grassei colonies. Green background = wood-dwelling life types; orange background = foraging life type. For protist functions involved in “information storage and processing” in the protist community, samples clustered according to life type. Similarly, the bacterial metabolic metagenomes clustered according to life type. Cluster dendrograms of all functional categories of protist and bacterial communities can be found in Additional file 1: Fig. S4 and S7
