Fig. 3.
The methanogen community structure and composition in the rumen of sika deer at three time points. a The methanogen composition at species level in the rumen at days 1, 42 and 70. PCoA results based on unweighted unifrac distance (b), weighted distance (c) and bray-curtis distance (d), and the within-, and between- group distance based on bray-curtis distance (e). Canonical correlation analysis (f) and heat-map (g) showing the significant methanogens in the rumen across three time points. Black circles indicate the representative taxon at each time points. The letter b indicates significant differences between day 42 and day 70. Mmc. = Methanomassiliicoccaceae; Mbb. = Methanobrevibacter. The asterisk means the unclassified methanogens at the family or genus level. R = Rumen
