Fig 2. Principal components analysis (PCA) of relative abundances.

Fig 2

PCA was used to compare variation of relative OTU abundances within and between liquid (L) and solid (S) rumen samples from groups R, A, RA and AA. Variation in individual samples is shown. Red = group R (LR and SR), blue = group A (LA and SA), green = group RA (LRA and SRA) and black = group AA (LAA and SAA). Individual animals are indicated by numbers (e.g. LRA55 and SRA55 are animal number 55, liquid and solid respectively, treatment group RA).
