Little is known about frugivory of epiphytes. We investigated diurnal frugivores consuming Aechmea depressa, an endemic species from Southern Bahia, Brazil, through 67 hours of observation on three fruiting individuals. Infructescences were visited for 2% of the time and only by golden-headed lion tamarins (GHLTs; Leontopithecus chrysomelas). Aechmea depressa invests on physical defense to retain fruits for prolonged periods, however, GHLTs used their small size and dexterity to remove rigid bracts and extract fruits from the infructescence. Prior studies indicate GHLTs disperse Aechmea seeds. Given the low visitation rates and probability that few frugivores successfully manipulate A. depressa fruits, we suggest that GHLTs are extremely important to... |

We studied the community and habitat occupation of epiphytes to understand how these plants cope with a supposedly stressful habitat: i) how general epiphytes occupy tree trunks, ii) how epiphytic bromeliads, occupy their supportive trees, iii) how CAM bromeliads are spatially distributed. The study was done in the dry forest of Jacarepiá, State of Rio de Janeiro. Data collection on epiphytes, phorophytes, and trees was based on the point-center quarter method. The photosynthetic pathway of the bromeliad species was determined using isotope ratio mass spectrometry. The presence of Gesneriaceae, Araceae, and Cactaceae indicates that some humidity is present in the area allowing the presence of supposedly less-specialized epiphytes. There was no correlation... |
