Resumen
Se analizó la dinámica de la producción de hojarasca del bosque de mangle en dos sitios de muestreo (Mariela y Magaly) del estero El Salitral-Biosfera de la Reserva La Encrucijada, Chiapas, México, en base a los datos de monitoreo realizado durante 48 meses de estudio. Se empleó la estadística descriptiva utilizando el modelo de regresión lineal y el análisis de varianzas. Dando como resultados que la producción de hojarasca fue de 926,19 ± 257,70 y 1261,64 ± 215,56 g m-2 año-1, mostrando un patrón estacional de productividad, con valores altos en la temporada lluviosa. Concluyendo que el sitio Magaly genera una producción mayor que el sitio Mariela al estar pasando por un proceso de restauración natural. Además, el patrón estacional se debe a la incidencia de dos variables importantes como son la precipitación y la salinidad que poseen una relación inversamente proporcional generando condiciones favorables para la producción de hojarasca.
The dynamics of leaf litter production of the mangrove forest in two sampling sites (Mariela and Magaly) of the estuary El Salitral-Biosfera de la Reserva La Encrucijada, Chiapas, México, was analyzed based on monitoring data during 48 months of study. Descriptive statistics were used using the linear regression model and analysis of variance. The results showed that litter production was 926,19 ± 257,70 y 1261,64 ± 215,56 g m-2 year-1, showing a seasonal pattern of productivity, with high values in the rainy season. Concluding that the Magaly site generates a higher production than the Mariela site as it is going through a natural restoration process. In addition, the seasonal pattern is due to the incidence of two important variables such as precipitation and salinity, which have an inversely proportional relationship, generating favorable conditions for litter production.
