Fig 2. Principal coordinate analysis of Bray-Curtis dissimilarities of bacterial (A), archaeal (B) and protozoal (C) community compositions in the rumen fluid of lambs fed fresh winter forage rape (rape) or fresh perennial ryegrass (grass).

The key to the right indicates the different forages and the time period of sampling [Period 1 (P1) or Period 2 (P2)]. The values in parentheses give the amount of variation explained by each coordinate.
