Relationship between wood density (WD) and (A) soluble sugars (SS) during the drought period (as a percentage of total non-structural carbohydrates, NSC); (B) relative change in SS between post-rain and drought periods (value in the post-rain period minus value in the drought period/value in the drought period); and (C) NSC depletion in plants with leaf loss, estimated as the ratio of NSC between undefoliated plants and plants with leaf loss in the post-rain period for each species. NSC and SS values were obtained by averaging stem and root values of all undefoliated and plants with leaf loss. R² values correspond to linear correlation coefficients. Species abbreviations are as in Fig. 4.
