From January to December 1999, the diet of Noctilio leporinus (Linnaeus, 1758) was determined in a salt-water ecosystem, by analysing the feces of bats captured in mist nets. Of the 61 samples analyzed, most contained remains of fish (90.2%), followed by insects (70.5%) and crustaceous (29.5%). The most frequent fishes species were: silversides Atherinella brasiliensis (Quoy & Gaimard, 1825), anchovies Cetengraulis edentulus (Cuvier, 1829) and scaly sardines Ophisthonema oglinum (Lesueur, 1818). The most frequent insects were moths (Saturniidae) and beetles (Cerambycidae, Scarabaeidae and Coccinellidae), as well as two species of bat ectoparasites (Streblidae). Among the crustaceous the shrimp (Palaemonidae) and crabs (Gecarcinidae) are was present. The consumption of fish, insects and crustaceans was different for the males and females throughout the year.De janeiro a dezembro de 1999, foi estudada a dieta de Noctilio leporinus (Linnaeus, 1758) em um ecossistema de manguezal, através da análise das fezes de morcegos capturados com redes-neblina. Das 61 amostras analisadas, a maioria continha fragmentos de peixes (90.2%), seguido de insetos (70.5%) e crustáceos (29,5%). As espécies de peixes mais freqüentes foram: peixe-rei Atherinella brasiliensis (Quoy & Gaimard, 1825), manjuba Cetengraulis edentulus (Cuvier, 1829) e sardinha Ophisthonema oglinum (Lesueur, 1818). Os insetos mais freqüentes foram mariposas (Saturniidae) e besouros (Cerambycidae, Scarabaeidae e Coccinellidae), além de duas espécies de ectoparasitas (Streblidae). Entre os crustáceos, houve a presença apenas de camarões (Palaemonidae) e siris (Gecarcinidae). O consumo de peixes, insetos e crustáceos foi diferente para machos e fêmeas ao longo do ano. |
