The contribution of animals to element fluxes in ecosystems is little known. We therefore estimated the contribution of a common frugivorous bat species (Phyllostomidae: Artibeus jamaicensis) to the base metal fluxes (Ca, Mg, and K) from fig trees to soil in a tropical lowland forest on Barro Colorado Island (BCI) because figs provide large parts of the Ca required by these mammals. We chose three...
Fruit-eating animals can influence the germination success of seeds through transportation and handling. We experimentally tested the contribution of ingestion by the common fruit-eating bat, Artibeus jamaicensis (Phyllostomidae, Chiroptera), to the percentage and rate of seed germination of figs (Ficus, Moraceae), which are considered keystone species for many frugivores. We collected fruits from...
To assess the influence of habitat fragmentation on small bats, we determined home range size and mobility of the frugivorousArtibeus watsoni Thomas, 1901 and the gleaning insectivorousMicronycteris microtis Miller, 1898 by radiotracking on different-sized islands (2.7–17 ha) in Lake Gatún, Panamá. The two species differed in their response to fragmentation. Home range size was highly variable in...
