Table S1. Relative abundance (%) of dominant genera in the Benthic, Pelagic and FPV compartments of the three studied lakes. The relative abundances were calculated based on the total abundance of the 23 genera that each had > 5% relative abundance in the initial dataset. Bold values represent the most abundant species in each compartment.

Table S2. Pairwise post hoc comparisons of taxonomic richness between the three compartments anal ysed in this study (Benthic, Pelagic, and FPV). Estimates represent the magnitude of differences between compartments, with associated standard error and p-values. Significant p-values are shown in bold.

Table S3. Pairwise post-hoc comparisons of Shannon diversity between the three compartments anal ysed in this study (Benthic, Pelagic, and FPV). Estimates represent the magnitude of differences between compartments, with associated standard error and p-values. Significant p-values are shown in bold.

Table S4. Pairwise post-hoc comparisons of Pielou's evenness between the three compartments anal ysed in this study (Benthic, Pelagic, and FPV). Estimates represent the magnitude of differences between compartments, with associated standard error and p-values. Significant p-values are shown in bold.

Table S5. Pairwise post-hoc comparisons to assess differences in diatom community composition across different combinations of habitat compartments (benthic, pelagic, and FPV) and seasonal periods (cold and warm seasons). Significant p-values are shown in bold.
