Structure and tree diversity in oak forests of central Mexico
The structure and tree diversity of oak forests in two micro-watersheds in central Mexico were characterized. The diameters (≥ 5 cm) and heights of the trees in circular plots of 1000 m2 were measured. The horizontal structure was analyzed based on the value of relative importance (VIR); the diamete...

| description | The structure and tree diversity of oak forests in two micro-watersheds in central Mexico were characterized. The diameters (≥ 5 cm) and heights of the trees in circular plots of 1000 m2 were measured. The horizontal structure was analyzed based on the value of relative importance (VIR); the diameters of six species shared at both sites were compared with the Mann-Whitney test, and the Pretzsch A index was used for the vertical structure. For alpha and beta diversity, PAS 4.3 software was used. In both cases Quercus laurina and Quercus rugosa obtained the highest values of density, dominance, and VIR; although there are no differences between the diameters, young specimens predominate (diameters 5 - 23 cm) and present a typical distribution of an inverted J, frequent in naturally regenerating forests. However, Quercus crassipes shows a decrease in individuals (< 15 cm), which suggests possible displacement. The vertical distribution indicates that the height is distributed mainly in stratum III (< 15 m). In terms of diversity, the difference is not significant, although the specific richness was 22 and 12 species in CPG and CRP, respectively, and there was? an intermediate replacement. The results of this work contribute to understanding the ecological processes of structure, diversity, and interaction between tree populations in these communities, so it is necessary to monitor especially species with behaviors such as Q. crassipes. |

Se caracterizó la estructura y diversidad arbórea de bosques de encino en dos microcuencas del centro de México. Se midieron los diámetros (≥ 5 cm) y alturas de los árboles en parcelas circulares de 1000 m2. La estructura horizontal se analizó con base en el valor de importancia relativa (VIR); se compararon los diámetros de seis especies que comparten ambos sitios con la prueba Mann-Whitney y para la estructura vertical se empleó el índice A de Pretzsch., mientras que para la diversidad alfa y beta se utilizó el software PAS 4.3. En ambos casos Quercus laurina y Quercus rugosa obtuvieron los valores más altos de densidad, dominancia y de VIR, aunque no existen diferencias entre los diámetros, predominan los ejemplares jóvenes (diámetros 5 cm – 23 cm) y presentan una distribución típica de J invertida, frecuente en bosques con regeneración natural. Sin embargo, Quercus crassipes muestra un descenso en individuos (< 15 cm), lo que sugiere un posible desplazamiento. La distribución vertical indica que la altura se distribuye principalmente en el estrato III (< 15 m). En cuanto a diversidad arbórea la diferencia no es significativa, aunque la riqueza específica fue de 22 y 12 especies en CPG y CRP, respectivamente, y hubo un recambio intermedio. Los resultados de este trabajo contribuyen a entender los procesos ecológicos de estructura, diversidad e interacción entre poblaciones de árboles de estas comunidades por lo que es necesario dar seguimiento sobre todo a especies con comportamientos como Q. crassipes.
