Abstract

Leaves of 208 trees were collected for isotopic analysis together with wood from 36 tree boles and 18 samples of fine litter from a terra-firme forest located at Samuel Ecological Reserve, Rondonia State, in the southwestern Amazon region. The range of delta^13 C values in leaves was from -28 to -36parts per thousand, with an average (+ or - 1 SD) of -32.1 + or - 1.5 parts per thousand, which was more negative than the delta^13 C values of bole samples (-28.4 + or - 2.0 parts per thousand) and fine litter (-28.7 + or - 2.0 parts per thousand). These values are within the range found for tropical and subtropical forests. Pooling the delta^13 C values for leaf samples from trees of the same height gave averages which were positively correlated with plant height at a highly significant level, with a slope of 0.06 and an intercept of -33.3 parts per thousand and a correlation coefficient r^2=0.70 (P < 0.001).
