Weighted-UniFrac comparison of microbial communities found in rumen samples based on Jaccard analysis of 97% similarity.

The P-value is a measure of the significance with which the microbial communities compared differ. P-values of <0.001 are highly significant, 0.001–0.01 are significant, 0.01–0.05 are marginally significant, 0.05–0.1 are suggestive and >0.1 is not significant. P-value ranges indicate the upper and lower limits of the calculation when multiple samples were compared.
