Supplementary material

Supplementary Table 1. Results of the Symmetric Co-Correspondence Analysis (sCoCA) assessing the shared variance between diatom species and trait assignments in mainland France.

Supplementary Table 2. Results of the Symmetric Co-Correspondence Analysis (sCoCA) assessing the shared variance between diatom species and trait assignments in French Guyana.

Supplementary Figure 1. Traits distribution in the phylogeny (based on rbcl).

Supplementary Figure 2. Ordination biplots for French Guyana obtained from symmetric co-correspondence analysis (sCoCA). Aerophilous (red solid square) /non aerophilous (light blue solid circles) are displayed in the left panel and species in the right panel. To improve the interpretation of the plots, species are colored based on their family and polygons represent the sampling sites from which they were sampled, regardless of their identification.

Supplementary Figure 3. Ordination biplots for Mainland France obtained from symmetric co-correspondence analysis (sCoCA). Benthic (red solid square) /non benthic (light blue solid circles) are displayed in the left panel and species in the right panel. To improve the interpretation of the plots, species are colored based on their family and polygons represent the sampling sites from which they were sampled, regardless of their identification.
