Mean index residual chronologies of tree-ring width (RW), wood density (RD) and element concentration of aluminum (Al), phosphorus (P), sulfur (S), potassium (K), calcium (Ca), manganese (Mn), iron (Fe), and strontium (Sr) from C. fissilis trees from southern Amazon and the total annual difference between precipitation and potential evapotranspiration (P-PET, time-scales from prior September to current September). Vertical light red boxes represent extreme drought events registered in the southern Amazon basin in 1981–1983, 1997–1998, 2005–2007, 2010–2011, 2014–2015 (Espinoza et al. 2019). On the right is the boxplot of normalized parameters in dry and wet years; a significant difference (SD) between means is also presented (p < 0.05)
