Table 1 Results of indicator analysis showing bacterial genera with significantly greater prevalence in breeding or non-breeding black rhinos. The average relative abundance of each genera across all rhinos, along with the percent variation with faecal progestagen (fPMC) and faecal glucocorticoid metabolite concentrations (fGMC), is provided for context

From: Rare gut microbiota associated with breeding success, hormone metabolites and ovarian cycle phase in the critically endangered eastern black rhino
