NMDS and ANOSIM Analysis. Red dots represent semi-wild Przewalski’s horses samples, and blue triangles represent captive Przewalski’s horses samples. NMDS analysis of samples representing the OTU community composition of intestinal microbiome in semi-wild and captive Przewalski’s horses. (A) was generated with unweighted UniFrac distance while (B) used weighted UniFrac distance. Stress lower than 0.2 indicates that the NMDS analysis is reliable. ANOSIM Analysis box showing the inter-group and intra-group beta distance between semi-wild and captive Przewalski’s horses. (C) was generated with unweighted UniFrac distance while (D) used weighted UniFrac distance. R-value range (0,1). R-value close to 0 represents no significant between inter-group and intra-group differences. R-value close to 1 shows that inter-group differences are greater than intra-group differences. P-value < 0.05 reflects significance of the R statistic.
