Fig. 3From: Dietary pea fiber increases diversity of colonic methanogens of pigs with a shift from Methanobrevibacter to Methanomassiliicoccus-like genus and change in numbers of three hydrogenotrophsHeatmap distribution of OTUs of methanogens for all colonic samples. OTUs are arranged in rows and clustered on the vertical axis (y-axis). Groups are arranged vertically and are on the horizontal axis (x-axis). Clustering was done for each using Phylotrac’s heatmap option with Pearson correlations and complete lineage algorithms. Different colors indicate relative abundance of the taxonsBack to article page
