Detection of differentially abundant bacteria between sample groups. (A) Among shared OTUs between wild and captive khulans, OTUs belonging to the families Lachnospiraceae, Rikenellaceae and class Kiritimatiellae are significantly more abundant in wild khulan microbiomes, while just Comamonas kerstersii is abundant in captive populations. (B) Water and sediment microbiomes show characteristic bacteria each, while water has significantly more abundant Bacteriovorax sp. and other Proteobacteria OTUs, members of the phyla Firmicutes from the family Clostridiaceae, are more abundant in sediment.
