Figure 2. Beta Diversity and Temperament in Boys.

Figure 2

Permutational multivariate analysis of variance indicated that microbial community structure was significantly different in boys with different levels of Surgency/Extraversion (p < .05). This was reflected in Principal Coordinate Analyses (PCoA) in which samples were plotted continuously based on ratings in A) Sociability/Extraversion and its subscales, including B) Sociability, C) High-Intensity Pleasure, and D) Activity subscales of the Surgency/Extraversion composite scale. Overall, samples were distributed on a gradient based on increasing temperament level. PCoAs were based on Unweighted UniFrac distances calculated by QIIME.
