Características foliares y tasas vitales de árboles sucesionales tardíos de un bosque tropical perennifolio

Abstract

Para acelerar la sucesión vegetal y restaurar la vegetación en áreas degradadas ( e.g ., pastizales abandonados) se ha sugerido utilizar especies sucesionales tardías. Para determinar cómo la dinámica foliar está relacionada con altas tasas de crecimiento y supervivencia en sitios sucesionales tempranos, evaluamos la hipótesis de que la plasticidad en la demografía foliar está positivamente correlacionada con el establecimiento de árboles de siete especies sucesionales tardías creciendo en ambientes soleados (pastizal y borde) y obscuros (bosque secundario) en Los Tuxtlas, Veracruz, México. Se monitorearon cohortes de hojas de 517 individuos de siete especies arbóreas creciendo en los tres hábitats durante un año. Los individuos que crecieron en bosque secundario y borde tuvieron mayor supervivencia foliar y menor producción de hojas que aquellos que crecieron en pastizal. Los individuos con mayor crecimiento y supervivencia en pastizal tuvieron una plasticidad alta en su supervivencia foliar y plasticidad baja en su producción de hojas (estabilidad), mientras que los individuos en el borde y el bosque con tasas altas de supervivencia fueron aquello que tuvieron estabilidad alta en su producción foliar. Nuestros resultados indican que Nectandra ambigens, Licaria velutina y Pouteria rhynchocarpa pueden ser sembradas en pastizales ya que muestran tasas altas de crecimiento y supervivencia en esos hábitats, además alcanzan diferentes estaturas a la edad adulta por lo que proveerían de diversidad estructural al bosque resultante. Especies con supervivencia baja en pastizales como Calophyllum brasiliense, Pimenta dioica, Amphitecna tuxtlensis y Eugenia inirebensis , podrían sembrarse en grandes cantidades o hasta que un dosel de pioneras se haya formado.
