### Drought Tolerance  
In terms of the leaf water potential at turgor loss (\(\pi\)TLP), among the monitored species, only one specimen showed resistance (id 284), based on the confidence interval (CI) established for seasonal tropical forests (\(\pi\)TLP \(>-\)3.01 MPa) based on [38]. Twelve specimens (id 382, 380, 381, 161, 32, 168, 286, 183, 489, 24, 36, 328) had moderate resistance (\(-\)1.69 \(\geq\)\(\pi\)TLP \(\geq-\)3.01 MPa), and nine species (id 288, 31, 29, 137, 27, 167, 102, 152, 20) had \(\pi\)TLP values within the low resistance class (\(\pi\)TLP \(>-\)1.69 MPa) (Figure 5). Specim id 254 does not have a \(\pi\)TLP measurement. Figure 3: Relationship between in situ and remote sensing data, RJA site.

Figure 5: \(\pi\)TLP of the species sampled by diameter (DBH). Threshold based on [38]. The individual with the smallest stem diameter (DBH \(\leq\) 20 cm) had more negative \(\pi\)TLP, with a mean of \(-\)2.2 \(\pm\) 0.74 MPa. Species with DBH \(>\) 20 cm represented the diameter class with the highest \(\pi\)TLP values, with a mean of \(-\)1.73 \(\pm\) 0.08 MPa (Figure 5). All classes presented mean values within the confidence interval from [38]. The mean of \(\pi\)TLP was \(-\)1.87 \(\pm\) 0.63 MPa, then the monitored trees can be classified as having moderate drought resistance. According to the P\({}_{50}\) confidence interval, based on [39], two specimens showed low resistance to drought (id 380, 382) (P\({}_{50}\) \(>\)\(-\)1.32 MPa), three specimens showed moderate resistance (id 381, 31, 137) (\(-\)1.32 \(\geq\) P\({}_{50}\)\(\geq\)\(-\)3.54 MPa), and five specimens had P\({}_{50}\) in the high resistance range (id 167, 168, 286, 183, 254) (P\({}_{50}\)\(<\)\(-\)3.54 MPa) (Figure 6). The other trees did not have P50 measured. Considering all analyzed individuals, the average P\({}_{50}\) for the plot was \(-\)3.25 \(\pm\) 1.51 MPa, which corresponds to the moderate drought resistance class. Individuals included in the \(\leq\) 20 cm diameter class (thin tree) had higher P\({}_{50}\) (\(-\)1.51 \(\pm\) 1.03 MPa), which is equivalent to lower resistance to drought, and individuals with DBH \(>\) 20 cm (large tree) had lower values (\(-\)3.63 \(\pm\) 1.21 MPa), which means higher drought resistance (Table 3). Isohydricity is a good indicator of limitations to stomatal function, in which isohydric behavior species have greater stomatal regulation and anisohydric show minimal stomatal regulation. In the RJA site, an anisohydric behavior was predominant among the species, in which 75% (dry season) and 76% (wet season) of the evaluated species showed fluctuations in leaf water potential (**VF**) throughout the day as weather conditions varied. The **VF** varied with air temperature in 63% of the species in the dry period and 82% in the wet season, with increasing temperature during the day. The results from the functional attributes
