Abstract

Frugivorous bats are important dispersers for many tropical plants and their conservation depends on furthering knowledge in their foraging behaviors and food preferences (Brosset et al. 1996). This study investigated a possible fruit preference of five frugivorous bat species (Carollia brevicauda, Artibeus lituratus, Artibeus jamaicensis, Artibeus toltecus and Platyrrhinus vittatus) found in Monteverde, Costa Rica among three wild fruit species (Solanum umbellatum, Solanum aphyodendron and Ficus pertusa) and two cultivated fruit species (Musa accuminata and Carica papaya). Fruits were presented to the bats in the Bat Jungle of Monteverde, where the foraging of bats can be closely observed. Artibeus toltecus showed a slight trend of preference for Solanum umbellatum over Solanum aphyodendron. However, due to small sample size and pseudoreplication there was no significant preference for any of the fruits by any of the bat species. Los murciélagos frugívoros son dispersores importantes de muchas plantas tropicales y su conservación depende del incremento de nuestro conocimiento de su comportamiento de forrajeo y preferencias dietéticas (Brosset et al. 1996). Este estudio investigó la posible predilección de cinco murciélagos frugívoros (Carollia brevicauda, Artibeus lituratus, Artibeus jamaicensis, Artibeus toltecus y Platyrrhinus vittatus) por tres especies silvestres de frutas Solanum umbellatum, Solanum aphyodendron y Ficus pertusa) y dos especies de frutas cultivadas (Musa accuminata y Carica papaya) en Monteverde, Costa Rica. Las frutas fueron presentadas a los murciélagos en la Jungla de Murciélagos de Monteverde, donde fue posible observar detenidamente el compartimiento de los murciélagos. Artibeus toltecus mostró una tendencia leve de preferencia por Solanum umbellatum. Sin embargo, debido al pequeño tamaño de la muestra y a la seudorreplicación, no se demostró ninguna preferencia significativa por cualquiera de las frutas de parte de ninguna de las especies de murciélagos.
