From: The piranha gut microbiome provides a selective lens into river water biodiversity
Diversity measures of Rio São Benedito water and piranha anal swab samples at the genus level for prokaryotic communities. (a) Alpha diversity represented by Shannon Index showing significant differences between anal swab and river samples (one-way ANOVA, P < 0.001). (b) Beta diversity represented by principal component analysis plot showing differences in the structure of prokaryotic communities from anal swab and river water samples. The axes show the Principal Components (PC), with PC1 and PC2 respectively explaining 65.5% and 22.8% of the total variance. Only entries where at least 10 reads were classified within a given sample from either swab or water metagenomes were used for diversity measures. Venn diagram representing unique and common counts of prokaryotic genera between (c) anal swabs, (d) water and (e) both sampling groups overall. For Venn Diagram counts, only entries where at least 10 counts were classified to a genus within an individual swab or river sample were included.
