| The maned wolf feeds mainly on fruits and small vertebrates. The diet of maned wolf was studied at Águas Emendadas Ecological Station (AEES) through 328 faecal samples collected from November 1996 to August 1999. To evaluate the seasonal variation in food availability, the fruit phenology of the wolf's fruit, the main food item in maned wolf's diet, was monitored counting the fruits produced in 20 marked plants. Fructification phenology of fleshy fruit plants in the cerrado habitat of AEES was recorded monitoring five plots of 100 x 20 m , where the number of fruit producing species and individuals were recorded. The diet composition was 60% vegetal items and 40% animal ones. The wolf's fruit, other fruits and small mammals were the most frequent consumed... |

| Some bat species seem to be lunar phobic, i.e., they avoid flying in bright areas or during bright periods of the night; however, the evidence is still controversial. We think that part of this controversy comes from pooling data on bat captures and moonlight intensity according to broad categories, such as moon phases, which conceal the high variability among nights. Therefore, we used detailed, long-term field data on three phyllostomid bat species, in order to test the hypothesis of lunar phobia at two different time scales: 1) among nights, by pooling data of different nights according to moon phases and testing for differences in the distribution of captures; and 2) within a night, by analyzing the relationship between capturability and moonlight... |

| ABSTRACT Neotropical bats are recognized as effective seed dispersers, especially of small-seeded pioneer plants during early stages of forest regeneration. There had been few reports on the ecology of the bat Pygoderma bilabiatum (Wagner, 1843), which appears to be mainly frugivorous and to undertake vertical migrations in Brazil. Our analyzes of fecal samples of P. bilabiatum specimens captured in mist nets and direct observations of their feeding behavior on Citharexylum solanaceum Cham. fruits in a mosaic of restored forests and forest fragments in southeastern Brazil constitute one of the few records of consumption of large-seeded fruits by P. bilabiatum, and indicate that it may be an important disperser for large-seeded plants. We found evidence... |

| This study was carried out at the Intervales State Park, an Atlantic Rain Forest area in Southeastern Brazil. Bats were monthly mist netted over a full year, and fecal samples were collected for dietary analysis. The seeds found in each sample were identified in the laboratory under a stereoscopic microscope by comparison with seeds taken from ripe fruits collected in the study area. Three hundred and seventy one bats were collected, of which 316 (85.2%) were frugivorous. The total number of fecal samples with seeds and/or pulp was 121. Sturnira lilium (E. Geoffroy, 1810) was the most abundant species in the study area (n = 157 captures) and Solanaceae fruits accounted for 78.5% of the fecal samples with seeds (n = 56). Artibeus fimbriatus Gray, 1838 (n =... |
