Table 2 Indicator analysis results identifying bacterial genera associated with different cycle phases, pregnancy and post-parturition. 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), are provided for context

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