NMDS ordination analysis among different mammal groups based on Bray–Curtis distance matrices using the TPM of six microorganism kingdoms. NMDS: (a) using all kingdoms at the species level; (b) using archaea at the species level; (c) using bacteria at the species level; (d) using fungi at the species level; (e) using protists and nematodes at the species level (in combination); (f) using viruses at the species level.
