Table I
List of the studied tree species and their systematic position. Mean values ( ± 95% confidence interval) of leaf mass-per-area (LMA, g m−2) and leaf thickness (μm) for leaves sampled under 20% of full irradiance are displayed. The number of samples (n), the parameters of the homographic models (α and β) and the coefficient of determination (R2) are indicated for the 13 studied species.
