Shown are the R2 values (percent variance explained) and P values for marginal PERMANOVA tests that evaluated whether hyena endogenous and exogenous factors predicted gut microbiome similarity (based on ASV abundances calculated from 16S rRNA gene data). The models utilized 3 types of distance matrices and included five host factors (hyena identity, matriline, age, mean monthly prey abundance, and year). n = 301 samples.
