Table 1 Summary of linear mixed models and post hoc tests on diversity measures of the gut bacterial microbiota (OTUs) in female and male beetles from rural and urban habitats. Values in bold denote significant (p < 0.05) effects. Results of the Tukey test indicate which habitat differed significantly (p < 0.05) from the other.
