Principal coordinate analyses of foregut and cecal communities of control and herbivorous-selected voles. Community membership uses unweighted UniFrac distances, and thus investigates the presence or absence of bacterial lineages. Community structure uses weighted UniFrac distances, which takes relative abundances of taxa into account. The points for cecal samples represent the same samples as presented in Figure 3, except here we used a lower number of sequences per sample for analysis, due to a slightly lower return of sequences from some foregut samples.
