Fig. 2From: Age and site-specific pattern on encrustation of charophytesComparison of carbonate content based on DW (%) of C. canescens (can), C. hispida (his), C. subspinosa (sub), and C. tomentosa (tom) from sampling sites (Angersdorfer Teiche, Asche, Bruchwiesen, Krüselinsee, and Lützlower See). Plants were analyzed in first to third (white), forth to sixth (light grey), seventh to ninth (dark grey boxplots) whorls and internodes. Box plots include whiskers (5–95% of variability) and outliers (points). Different letters indicate significant difference within the same sampling site (Tukey HSD post hoc test, p < 0.05)Back to article page
