| description | Forest succession was studied in sub-tropical high-altitude, Quercus-dominated forest in west-central Mexico in order to address the following research questions: (1) How do successional trajectories progress in three contrasting floristic zones? (2) Which is the magnitude of successional rate of change at different time-scales? (3) What are the major environmental drivers contributing to the observed patterns of forest succession? Data was derived from 86 non-managed permanent plots, 500 m2 each, established along a 10 km floristic gradient, ranging from xeric to mesic sites. In portraying successional trajectories over time and to measure the magnitude of rate of change in three floristic zones, Detrended Correspondence Analysis (DCA) was developed. In order to represent the most significant environmental drivers on patterns of successional trajectories and successional rate of change, we used generalized linear models with gaussian error. Results showed that successional trajectories were not deterministic in each of the floristic zones over the different time-scales analysed; instead we observed four successional trajectories i) plots with an outstanding displacement between time periods, accompanied by an erratic migration over the DCA diagram; ii) plots with a moderate rate of change and uniform movement across the ordination space; iii) a small number of plots with slight change and; iv) few plots with no changes. Soil related variables such as pH, P, N, Mg and Mn, together with slope and catena, were predicted as important contributing factors related to successional processes. |

Se estudiaron las tendencias de sucesión forestal en bosques subtropicales de alta montaña dominados por Quercus en el centro-occidente de México; el propósito de este estudio fue responder las siguientes preguntas de investigación: (1) ¿Cómo se desarrollan las trayectorias sucesionales en tres zonas florísticas contrastantes? (2) ¿Cuál es la magnitud de la tasa de cambio sucesional en diferentes escalas temporales? (3) ¿Cuáles son los principales factores ambientales que contribuyen con los patrones observados en la sucesión forestal? Los datos para el presente estudio provienen de 86 sitios permanentes de 500 m2 establecidos a lo largo de un gradiente florístico de 10 km. Se utilizó Análisis de Correspondencia Desprovisto de Tendencia para cuantificar las trayectorias sucesionales, así como para estimar la magnitud de la tasa de cambio en cada una de las zonas florísticas estudiadas. Para discernir los factores ambientales significativos con relación a las trayectorias sucesionales y las tasas de cambio del último censo, se utilizaron modelos lineales generalizados con error gaussiano. Los resultados muestran que las trayectorias sucesionales no fueron deterministas para las tres zonas florísticas en las diferentes escalas de tiempo analizadas; por el contrario se observaron cuatro rutas diferentes de sucesión i) sitios con desplazamiento notorio entre periodos de tiempo, acompañados por un desplazamiento indeterminado sobre el diagrama de ordenación; ii) sitios con una tasa de cambio moderada y movimiento uniforme a lo largo del espacio de ordenación; iii) un pequeño número de sitios con cambio leve y; iv) pocos sitios sin cambio aparente. Variables relacionadas con el suelo como pH, P, N, Mg y Mn, así como la pendiente y la posición en la catena, fueron las variables explicativas que contribuyeron a explicar la tasa de cambio en los procesos sucesionales.
