The table shows the statistics for each microbiome as follows: the percentages of genes belonging to distinct GH families involved in lignocellulose degradation, the number of all genes encoding GHs, the number of total bases in the assembled contigs, and the density of the GH genes in the metagenome assemblies of individual herbivores
