The long-term gut bacterial signature of a wild primate is associated with a timing effect of pre- and postnatal maternal glucocorticoid levels

Reduced model 1c explaining the Faith’s phylogenetic diversity (PD) of offspring’s gut bacteria. Significant p-values of explanatory variables are in italics. R² indicates the conditional coefficient of determination. All covariates are log_n-transformed and then z-transformed (mean = 0, SD = 1) to meet model requirements and increase model interpretability
