Notes

Abstract: The allometric relations of diameter and height were analyzed for 34 tree species of the Imataca Forest Reserve, according to the Chapman and Richard equation used in the individual-based ZELIG and FACET models that simulate forest dynamics. The two allometric coefficients employed were calculated by linear regression applied to the logarithmic transform of the equation. The exponential equation was found to explain a large proportion of the variability in height even though the data came from different sites. The relationships will be employed in FACET for future work. The existence of allometric patterns was evaluated after grouping species according to light requirements (shade-intolerant or pioneer and shade-tolerant) and maximum height classes (medium 10-30m, and large >30m), forming four functional groups: medium-pioneer, large-pioneer, medium-tolerant, and large-tolerant. Differences were found in allometric coefficients between the groups, using analysis of variance and discriminant analysis. The differences in the allometric coefficients, taken one at a time, are more significant between pioneer and tolerant than between medium and large. The combination of both coefficients, b2 y b3, emphasizes differences among all groups, specially when using a linear discriminant function, which in addition, will allow predicting to what group a species may belong, given the values of its allometric coefficients.
