Values represent average abundance of each variable followed by the percent contribution in parentheses. NP, Non-photosynthetic above-ground tissue; Temp, temperate; Trop, tropical; Atl, Atlantic. Thermal intervals (TI) represent distinct organic matter components from TGA normalized to total organic matter (TI1: labile, carbohydrates, hemicellulose, 180–220°C; TI2: labile, carbohydrates, hemicellulose, 220–300°C; TI3: refractory, cellulose, 300–400°C; TI4: refractory, lignin and residues, 400–600°C).
