(A) Principal component analysis (PCA) of the combined bacterial (16S rRNA gene), archaeal (16S rRNA gene) and anaerobic fungal (5.8S rRNA gene) qPCR data for rumen fluid (RF, Δ) and fibrous content (FC, aaa) samples. The GS100 diet has duplicate DNA extracts presented as individual datapoints. The percentages provided at the axes indicate the variation explained. (B) The corresponding loadings for the principal components indicate that anaerobic fungi are the major cause of sample separation in PC1, and archaea in PC2.
