Bird community composition of two riparian forests at Jacaré-Pepira river, São Paulo, Brazil
A quali-quantitative survey was carried out in two riparian forests fragmente (approximately 40 ha each) at Jacaré-Pepira river. Our intention was to characterize its bird community conceming richness, abundance and species occurrence in these areas. The qualitative survey showed 130 species at Santa Elisa (Brotas, São Paulo) and 151 at Morro Chato (Dourado, São Paulo), whereas the quantitative survey revealed the presence of 69 and 75 species at Santa Elisa and Morro Chato, respectively. The small size and the isolation might be responsible for the low number of species found. Observing the abundance index values (IPA) we realize that there are a few number of species with a high IPA on the one hand, while on the other there is a large number of species with intermediate and low IPA rates. A high detection coefficient (vocalization), low predatoiy rates and competition might have contributed for the higher abundance values found among these species. Furthermore, we have also registered species which are abundant in a fragment, but absent in the other, which might be explained by initial exclusion or local extinction. In spite of the riparian forests being protected by law, its clearing process has not stopped yet. Therefore, the study of this bird community is of uppermost impoitance for the elaboration of both conservation and management projects regarding these areas.10871098Conselho Nacional de Desenvolvimento CientÃfico e Tecnológico (CNPq

Composition and dynamics of the bird community of mata de Santa Genebra, Campinas, São Paulo, Brazil
A quali-quantitative survey of avifauna was earried out at the Santa Genebra forest reserve (MSG) in order to evaluate the current state of conservation of this important conservation area in the interior of São Paulo Stale. The qualilative survey recorded 134 species and the quantitativo survey through unlimited distance point counts recorded the abundance of 97 species. The low number of species recorded in both surveys was due to the small size (251 ha) and the high degree of isolation of the MSG. These factors plus the extensivo degradation of the forest cover prevent recolonization of extinct species and allow the expansion of some species tolerant to disturbance. The quantitative survey showed some species with an unusually high abundance index. The abundance of most species at MSG is higher whon compared with other areas of similar vegetation which are not fragmented and isolated, There was no striking seasonal variation in the number of birds recorded. These caracteristics could be interpreted as resulting from the density compensation phenomenon. The structure of the bird community of MSG resembles that from an island with low number of species but overall density similar to that of the mainland, leading to a higher density per species. The process responsible for these patterns seems to be related to the habitat appropriateness, mainly because the MSG is completely isolated from other forest arcas.49351

The song of the Brazilian population of Humpback Whale Megaptera novaeangliae, in the year 2000: individual song variations and possible implications
The song of the Brazilian population of the Humpback Whale Megaptera novaeangliae was studied in its breeding and calving ground, the Abrolhos Bank, Bahia, Brazil, from July to November 2000. Aural and spectral analyses of digital recordings were completed for approximately 20 song cycles, totaling 5 hours of song from 10 different recording events. We identified 24 note types, organized in five themes. All songs presented the same themes and the order in which they were sung did not vary. We registered the appearance of a note type and the disappearance of a phrase ending, which indicate that the song changed as the season progressed. Moreover, we detected individual variation in the way singers performed certain complex note types. As songs are transmitted culturally, it is likely that singers have different abilities to compose and/or learn new notes. If, as it has been previously suggested, 'new' songs are preferred to 'old' ones, these more able singers will be sending out information about their learning abilities that could be used by other whales to decide whether or not to interact with them
