Table 2.

Back-transformed weighted means and respective 95% confidence intervals of carbon stocks in above-ground biomass (AGB), root biomass (RB), and total tree biomass (Mg C ha⁻¹) between different land-uses in three regions of Mexico. Tree total biomass: AGB + RB. Superscript uppercase letters indicate significant differences between land-uses, while lowercase letters indicate statistical differences between geographical regions (Tukey HSD, p < 0.05).
