Distribution and structure of the population of Abies religiosa (H.B.K.) Schl. et Cham., in the Cofre de Perote, State of Veracruz, Mexico
Analysis of relative frequency and multiple correlations were used to determine altitude, slope, and exposure of places where Abies religiosa (H.B.K.) Schl. et Cham. Is found in the Cofre de Perote area, state of Veracruz, Mexico. This study includes a population structure analysis, as well as an an...

| description | Analysis of relative frequency and multiple correlations were used to determine altitude, slope, and exposure of places where Abies religiosa (H.B.K.) Schl. et Cham. Is found in the Cofre de Perote area, state of Veracruz, Mexico.
This study includes a population structure analysis, as well as an analysis of the relationships between the common annual increment (CAI), the variables mentioned above and the coverage, the standing tree basal areas, and the stump basal areas.
The results show that the fir forest is restricted to certain slope and altitude conditions. This is due primarily to the loss of forested land to agriculture. There is a 0.579 probability of finding fir trees at altitudes between 3200 and 3400 meters and on slopes of 40% to 55%. With respect to exposure, the NW side shows the greatest frequency (58%).
A high correlation (r=-0.96) was found between the normal diameter (ND) and the age of the trees. Moreover, the age structure is that of a shade-tolerant species. Finally, a positive relationship was found between CAI, the stump basal area, and the slope (r=0.77, p<0.001). |

This study includes a population structure analysis, as well as an analysis of the relationships between the common annual increment (CAI), the variables mentioned above and the coverage, the standing tree basal areas, and the stump basal areas. The results show that the fir forest is restricted to certain slope and altitude conditions. This is due primarily to the loss of forested land to agriculture. There is a 0.579 probability of finding fir trees at altitudes between 3200 and 3400 meters and on slopes of 40% to 55%. With respect to exposure, the NW side shows the greatest frequency (58%). A high correlation (r=-0.96) was found between the normal diameter (ND) and the age of the trees. Moreover, the age structure is that of a shade-tolerant species. Finally, a positive relationship was found between CAI, the stump basal area, and the slope (r=0.77, p<0.001). Se usó la frecuencia relativa y las correlaciones múltiples paso a paso para determinar las condiciones de altitud, pendiente y exposición bajo las cuales habita Abies religiosa (H.B.K.) Schl. et Cham. en la región del Cofre de Perote, estado de Veracruz, México. El estudio también incluyó el análisis de la estructura de edades de la población, así como la relación entre el Incremento Corriente Anual (ICA), las variables arriba mencionadas y los atributos tales como cobertura, área basal del arbolado en pie y área basal de tocones. Los resultados indican que los bosques de oyamel se encuentran en condiciones de pendiente y altitud restringidas, hecho que se tribuye principalmente al reemplazo de la masa forestal por cultivos agrícolas. En la zona de estudio, la pendiente y la altitud que resultaron con mayor probabilidad (0.579) de encontrar a Abies religiosa correspondieron a los intervalos de 40-55% y de 3200-3400 metros, respectivamente. La exposición NW fue la más frecuente (58%) entre los sitios de oyamel muestreados. Se obtuvo una alta relación (r=0.96) entre el diámetro normal (DN) de los troncos y la edad. Asimismo, se estimó la estructura de edades que resultó ser característica de una especie tolerante a la sombra. Finalmente se encontró una relación positiva entre el ICA con respecto al área basal de los tocones y al pendiente (r=0.77, p<0.001).
