Diversity parameters of diatom assemblages: box plots for (a) read numbers, (b) Shannon index, (c) number of OTUs and (d) number of taxa for the three preservation methods (blue: ET, yellow: FR, grey: RL) for marine (LC, ES) and freshwater sites (OF, MS, EG, HF). Boxes represent the interquartile range, with the median indicated with a line and whiskers extending to the highest and lowest values.
