From: Investigating carbon dioxide absorption by urban trees in a new park of Bangkok, Thailand
Tree species with sensitive responses of the CO2 absorption (A, μmol m−2 s−1) to vapor pressure deficit (VPD, kPa) in both wet and dry seasons (a, b) and those with insensitive responses (c, d). Closed (open) symbols represent A averages for the wet (dry) season with one standard deviation shown as error bars. Solid lines show significant regression patterns at 0.05 level with 95% confidence intervals shown as dashed lines. Regression equations are listed in Table 1
