In this paper it was tested the independence of diameter structures of oak and pines sharing resources in forest stands of the western Sierra Madre mountain range of Durango, Mexico with the aim to detect ecological interactions between these two genera. Regression analysis was conducted on the weibull distribution parameters fitted independently to diameter structures of pines and oaks. The moments methodology of parameter estimation of the Weibull distribution was fitted. This procedure was independently carried out for pine and oak diameter structures of mixed and uneven-aged forests. The regression analysis conducted on the weibull parameters for pines and oaks did not show patterns or tendencies with sufficient statistical meaning. Indeed the diameter structures of pines and oaks are quite similar and showed little sensitivity to changes in the weibull parameters stressing the potential independence of diameter growth of pines and oaks. Further research is required to understand the ecological interactions between oaks and pines, at the species scale, with the aim to develop growth and yield models to sustainable manage the mixed, uneven-aged coniferous forests of Durango, Mexico. Resumen En este reporte se probo la independencia de las estructuras diametricas de pinos y latifoliadas compartiendo los bosques de la Sierra Madre Occidental de Durango, Mexico, con el objetivo de detectar relaciones ecologicas entre estos dos generos. Se realizaron analisis de regresion entre los parametros de la distribucion weibull, ajustados independientemente a las estructuras diametricas de pinos y latifoliadas. Se uso la metodologia de momentos para estimar los parametros de la distribucion Weibull. Este procedimiento se realizo independientemente para las estructuras diametricas de pinos y latifoliadas de los bosques mixtos e irregulares de Durango, Mexico. Los analisis de regresion, realizados entre los parametros de la distribucion Weibull, no mostraron tendencias o patrones con significado estadistico suficiente. Las estructuras diametricas de pinos y latifoliadas son muy similares y mostraron baja sensibilidad a los cambios en los parametros de la distribucion Weibull estresando la potencial independencia en el crecimiento diametrico de pinos y latifoliadas. Se requiere investigacion adicional para entender las interacciones ecologicas entre las latifoliadas y los pinos, a la escala de especie, con el objetivo de desarrollar modelos de rendimiento e incremento para manejar sosteniblemente los bosques mixtos e irregulares de coniferas de Durango, Mexico.
