<strong>Supplementary information</strong> <strong>Supplementary Figure S1</strong>. Maps showing the sampling area (left) and localities (right) in France. Forests are indicated in green and water in blue. The four sampling localities are represented with a colored polygon. The arrow indicates the North. <strong>Supplementary Figure S2</strong>. Composition of the gut bacteriota. The relative abundance of six phyla representing 99% of the total composition is represented. Individuals are grouped by sampling localities, which are ordered from North to South. (A) Bar graph shows individual variation in phyla composition (phylum=color). (B) Box and whisker plots represent median and interquartile values for each phylum. Black dots correspond to mean values, and colored dots correspond to individuals. <strong>Supplementary Figure S3</strong>. Variations of alpha diversity with individual factors, for the gut bacteriota (family level), pathogenic bacteria and gastro-intestinal helminths of bank voles. Alpha diversity is estimated using the specific richness (A, B and C) and the Shannon index (D, E and F). In graphs C and F, the blue line corresponds to the linear regression line. <strong>Supplementary Figure S4</strong>. Relationships between the composition of the gut bacteriota, pathogenic bacteria and gastro-intestinal helminth communities: The db-RDA triplot shows the structure of the gut bacteriota at the phylum level and the correlations with the intra-host parasite communities. The arrows correspond to the significant explanatory variables. Each point corresponds to an individual, and the colors correspond to the different sampling localities. <strong>Supplementary Table S1. </strong>Variation of the Firmicutes/Bacteroidetes ratio with localities and individual factors. <strong>Supplementary Table S2. </strong>Alpha diversity metrics and statistics for the gut bacteriota, pathogenic bacteria and helminth communities of bank voles. <strong>Supplementary Table S3. </strong>Beta diversity metrics and statistics for the gut bacteriota, pathogenic bacteria and helminth communities of bank voles
