8. J. dos Santos, thesis, Univ. Federal de Vicosa, Brazil (1996). The allometric equation is AGBM = (exp{3.323 + [2.546 × In (DBH/100)]}) × 600. The 319 trees used to derive the equation ranged from 5 to 120 cm DBH and were destructively sampled to determine AGBM. The trees were randomly selected at a site about 20 km southwest of our study area, in very similar lowland terra firma forest.
9. -1 (mean ± SD). In parts of the Amazon, the carbon content of soil below a depth of 1 m may rival or exceed that of AGBM [D. C. Nepstad et al., Nature 372, 666 (1994)].
