### Study Plot and Plant Species  
In the RJA site, we built a plot of 5 ha (250 \(\times\) 200 m) long (10\({}^{\circ}\)11\({}^{\prime}\)11.39\({}^{\prime\prime}\)S, 61\({}^{\circ}\)52\({}^{\prime}\)20.89\({}^{\prime\prime}\)W, with 153 \(\pm\) 7 m altitude above sea level) (Figure 1). In the plot, we selected 31 tree individuals with diameter at breast height (DBH \(>\) 10 cm), covering 23 representative species of the area. The individual selection was based on the relative density (Rd) and value of importance index (IVI) phytosociological parameters (Table 2). For the selected trees, we measured the DBH, height followed by the botanical identification. The basal area of the selected trees covers 24.97 \(\pm\) 0.1 m\({}^{2}\).ha\({}^{-1}\) and DBH of 21 \(\pm\) 14 cm.ha\({}^{-1}\), with a DBH range of 10 to 117.5 cm. The trees average 19.29 \(\pm\) 9.4 m in height and some species reach up to 55 m.  
The RJA site has a variable topography, from flat relief (0-3% slope) to strong wavy (20-45% slope). The soil has a clayey texture above 60%, with medium fertility of organic matter (2.01 \(\leq\) MO \(\leq\) 4.0) up to a layer of 0.20 m and very high acidity. The concentrations of the macronutrients P, K, Ca, Mg and Al are higher at 0.20 m, and from 0.40 m onwards, the concentration of these nutrients drops abruptly to low and even zero levels, especially in the case of phosphorus and potassium, which reach zero levels in the deeper layers of the soil. \begin{table}
