          Abstract

          Resumen Manilkara zapota es una especie forestal abundante y con importancia comercial maderable. Estimar el volumen y proyectar la distribución de productos maderables para realizar un inventario preciso contribuye al manejo de la especie. El objetivo fue ajustar modelos de volumen fustal (Vf) y ahusamiento (d) para árboles de M. zapota que crecen en los bosques tropicales del centro y sur del estado de Quintana Roo, México. Se usó un total de 186 árboles para ajustar 10 modelos mediante máxima verosimilitud: ocho para Vf y dos en d. Utilizando los valores en los estadísticos del coeficiente de determinación, raíz del error cuadrático medio (RMSE) y valores de verosimilitud, los modelos de Schumacher-Hall y Cielito 3 fueron seleccionados para estimar el Vf y d, respectivamente. Se explicó más del 93% de la muestra empleada con una desviación global menor del 6.5%, donde el factor de forma promedio fue de 0.5.

          Abstract Manilkara zapota is an abundant forest species with commercial timber importance. Estimating the volume and projecting the distribution of timber products to carry out an accurate inventory contributes to the management of the species. The objective was to adjust models of stem volume (Vf) and taper (d) for M. zapota trees growing in the tropical forests of the center and south of Quintana Roo, Mexico. A sample of 186 trees was used to fit 10 models by maximum likelihood: eight for Vf and two for d. Using the values in the statistics of the coefficient of determination, root mean square error (RMSE) and the Akaike and Bayesian Criteria, as well as the logarithm of maximum likelihood, the Schumacher-Hall and Cielito 3 models were selected to estimate the Vf and d, respectively. More than 93% of the sample used was explained with a global deviation of less than 6.5%, where the average form factor was 0.5.
