Abstract

A large portion of Neotropical forests are being or have been cleared for agriculture and pasture. Conserving biodiversity in these areas, therefore, will depend on efforts to restore degraded habitat. In order to examine the influence of remnant trees on regeneration in a secondary tropical forest in Costa Rica, this study compared the species composition of plants and seedlings beneath a bird dispersed tree species, Zanthoxylum fagara (Rutaceae), and a ballistically dispersed tree species, Croton draco (Euphorbiaceae), There was no statistical difference found between the two, but when both data were combined, a higher percentage of bird and bat dispersed species was seen in the study site than is typical for local forests. Based on the seedling pool, birds and bats were also the only significant dispersers of primary forest species into the area. These data suggest that dispersal limitations are affecting the species composition and succession processes of the forest. La mayoría de bosques neotropicales se están destruyendo o ya se han destruido para uso en agricultura o pasto. Por eso, es probable que los esfuerzos de reforestación de áreas degradadas sean importantes para conservar la biodiversidad. Para examinar la influencia de árboles dejados en pastos en la regeneración de bosques, compare las especies de plantas bajo dos especies de árboles, Zanthoxylum fagara (Rutaceae) (dispersado por ave) and Croton draco (Euphorbiaceae) (dispersado por tirar), en un bosque secundario en Costa Rica. No había una diferencia entre las dos especies, pero el porcentaje de especies bajo todos los árboles fueron dispersados por aves y Murciélagos fue más alto que el de la región de Monteverde. También, aves y murciélagos fueron los únicos dispersores importantes de especies de bosque primario en mi sitio. Esta información sugiere que limitaciones de dispersión está cambiando que tipos de plantas y árboles están en el sitio de estudio.
