Tesis (M. Sc) -- CATIE, Turrialba (Costa Rica), 2011 Se evalu? la dispersi?n, remoci?n y depredaci?n de semillas de C. brasiliense en un bosque afectado por el hurac?n F?lix y otro sin perturbaci?n en la Regi?n Aut?noma Atl?ntico Norte de Nicaragua (RAAN), ambos sitios de estudio se encuentran desprovistos de actividades de cacer?a. Se midi? el destino (removida y no removida) de cada semilla, la distancia de remoci?n y se determin? si existi? una dispersi?n efectiva (semillas enterradas y abandonadas). Finalmente, se evalu? la abundancia y riqueza de mam?feros medianos mediante caminatas diurnas y roedores peque?os a trav?s de capturas con trampas Shermann en ambos sitios de estudio. Finalmente, se recomienda planificar el manejo forestal de C. brasiliense cuando los valores de dispersi?n sean mayores y con ello incrementen potencialmente los bancos de regeneraci?n. I evaluated the seed fate of animal-dispersed timber species Calophyllum brasiliense in hurricane-impacted forests by 2007 Hurricane Felix in the North Atlantic Autonomous Region (RAAN) of Nicaragua. I quantified the rates of seed removal, seed distance, dispersal and seed predation in both hurricane-impacted and undisturbed forests. The distance of seed removal was significantly higher in the undisturbed forest site. Finally, we recommend managing this species when seed dispersal values are higher and could potentially result in successfully established banks of regeneration.
