The species (taxa) richness (Margalef’s index) was significantly lower in June compared to the other study periods (Tukey–Kramer test, p < 0.01), while there were neither significant differences in Pielou’s evenness (one-way ANOVA, p = 0.07)
nor Shannon–Wiener diversity (one-way ANOVA, p = 0.05) (Table2).
