Title Supplementary Table 1
Description Monte Carlo calculation mean differences on richness (S), Simpson (1-D) and Shannon (H’) diversity indices and associated p-values comparing LAs (living assemblages) and DAs (dead assemblages) and open water and littoral environments from Las Mostazas (LM), Los Carpinchos (LC) and Nahuel Rucá (NR). Significant values at α = 0.05 are in boldface.

Title Supplementary Table 2
Description List of diatom species mentioned in the text, their authorities and life form, salinity and nutrient classifications (according to de Wolf, 1982; Denys, 1991/1992 and Van Dam, 1994). E: epiphyte; B: benthic; Aer: aerophilous; P: plankton; Tp: tychoplankton; H: halophobous; OI: oligohalobous indifferent; OH: oligohalobous halophilous; M: mesohalobous; PO: polyhalobous; Dys: dystrophic; Eu: eutrophic; Mt: mesotrophic; Ot: oligotrophic; I: indifferent.

Title Supplementary Table 3
Description Results of HMD (Homogeneity in Multivariate Dispersions) tests comparing live and dead diatom assemblages in total (littoral+open waters), littoral and open waters datasets showing: ratio (premortem variation/total LD variation), the estimates of premortem and postmortem variation, the significance values of modified test of multivariate dispersions, which indicates whether variation among DAs and the centroid of LAs is larger (overdispersion) or smaller (underdispersion) than variation among LAs and their centroid. NS= not significant at α = 0.05.

Title Supplementary Table 5
Description Gradient lengths and results of CCA ordinations of live and death diatom assemblages against vegetation cover (veg) and depth in the three studied lakes. Significant ordinations at α = 0.05 are in boldface.

Title Supplementary Table 7
Description Percentage variance explained by each environmental variable in LAs and DAs as calculated by partial CCA. The significance is indicated based on 199 unrestricted ANOVA like permutations (p < 0.05*, p < 0.01**, p < 0.001***).
