RESUMENCon el fin de determinar si los micrositios de establecimiento están limitando el reclutamiento de las plántulas y la regeneración de Espeletia uribei, un frailejón endémico y valor objeto de conservación del Parque Nacional Natural Chingaza, se evaluaron diez variables bióticas y abióticas dentro de micrositios con plántulas y micrositios vacíos. Las variables que más se relacionaron con el establecimiento fueron: la distancia al adulto reproductivo más cercano, el tipo de zona de luz "abierta" y la estructura de vegetación "herbácea" asociada. La distancia al adulto reproductivo más cercano dificulta que las semillas alcancen micrositios más alejados debido al tipo de dispersión primaria barócora de la especie. Zonas de luz "abiertas" y vegetación asociada herbácea condicionaron la capacidad de germinación y establecimiento de la especie. Los resultados mostraron que el reclutamiento de E. uribei está limitado por la disponibilidad de micrositios que reúnan estas condiciones, un factor que es importante considerar para el planteamiento de futuros proyectos de manejo para la conservación y restauración de las poblaciones de la especie.Palabras clave: distancia al adulto, frailejón, luz, microhábitat, páramo, reclutamiento, vegetación asociada. ABSTRACTIn order to determine whether microsites are limiting seedling recruitment and regeneration of Espeletica uribei (an endemic frailejon, a valuable species subject to conservation in the Parque Nacional Natural Chingaza) ten biotic and abiotic variables were evaluated from E. uribei seedling microsites as well as from sites without seedlings. The variables associated with seedling establishment were distance from the nearest reproductive adult, the quality of exposure to light, and associated herbaceous structure. Reduced distances from the nearest reproductive adult made it difficult for the seeds to reach distant microsites due to the principle wind dispersal type (anemochory). Open gaps and associated herbaceous structure positively affect the germination capacity and establishment of the species. The results suggest that E. uribei recruitment is limited by the availability of microsites that meet these conditions. These are important factors to consider when planning future projects for the conservation and restoration of this species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
