Figure 3. — Boxplot chart with (A and C) δ²H (in ‰, VSMOW) and (B and D) δ¹⁸O (in ‰, VSMOW) for the sampled xylem water of canopy lianas (orange), trees (green) and the bulk soil water samples at various depths (gray), derived from both the sandy (A and B) and clayey (C and D) plots. Orange and green shaded rectangles illustrate the interquartile range (IQR) of xylem water values for canopy lianas and trees, respectively. Boxplots show Q25 – 1.5 IQR, Q25, Q50, Q75 and Q75 + 1.5 IQR values. Outliers are shown by open circles. Statistical differences are indicated by different letters (non-parametric Kruskal–Wallis test with Dunn post hoc analyses, P < 0.05).
