Relative abundance of predominant OTUs (percentage) in the feces of five African white rhinoceroses1.

1Thirty-seven OTUs with abundances higher than 0.5% in the microbial community were sorted from a total of 1409 OTUs, and defined as predominant OTUs.2The consensus sequence of each OTU was annotated to the closest lineage using the MOTHUR program against the SILVA 16S rRNA reference database. s: = species; g: = genus; f: = family; o: = order; c: = class; p: = phylum.
