Fig. 6From: Multilevel social structure and diet shape the gut microbiota of the gelada monkey, the only grazing primateDifferences in within-group Bray-Curtis distances (a), Shannon entropy (b), and OTU richness (c) between geladas (n = 39) and sheep (n = 29). Each box represents the interquartile range, with the horizontal lines representing the medians and the whiskers representing 1.5 times the interquartile range. Points outside the whiskers represent outliers. In a, the between-sample distances were significantly reduced in the sheep relative to the geladas (p < 0.001, unpaired t test), while the mean distance between geladas and sheep (She/Gel) was close to one. Diversity was significantly elevated in sheep relative to geladas (p <  0.001 for both comparisons, unpaired t tests)Back to article page
