From: Host-associated microbiomes are predicted by immune system complexity and climate
Path model of internal microbiomes depicting direct and indirect effects of immune complexity in the context of the best biotic and abiotic predictors of microbial phylogenetic diversity. Numbers are standardized path coefficients. Blue arrows depict positive associations whereas red arrows depict negative effects at P < 0.05. Gray arrows depict non-significant paths. The thickness of the arrows represents the relative strength of each relationship
