Figure 4.
Total mean MAA concentrations (µg µg dry weight−1) in the different life stages nauplii, copepodid CI-CIV, and copepodid CV to adult of Cyclops abyssorum tatricus from six alpine lakes sampled during the ice-free period of 2010 and 2011. The lakes are ordered from clear to turbid (abbreviations for the lakes are defined in Table 1). Error bars indicate +1 standard deviation. Different letters above the bars indicate a significant difference found with one-way ANOVA all pairwise comparison procedures (Holm-Sidak method, F5,12 = 11.36, p < 0.001 for nauplii), and Kruskal-Wallis one-way ANOVA on Ranks, all pairwise multiple comparison procedures (Dunn’s method, p < 0.05 for CI-CIV and CV-adult). White bars: clear lakes, blue bars: turbid lakes. Nauplii were not present in all lakes at the time of sampling. Copepodid CI-CIV and CV-adult were not present in Lakes FAS6 and MUT, respectively, at the time of sampling.
