“…The importance of E. edulis in the Atlantic Rain Forest is due also to the great availability of fruits produced annually, which can reach up to 377.000 ha -1 year -1 (Reis & Kageyama 2000). They serve as a main source of food to many mammals and large birds (Galetti & Chivers 1995, Galetti et al 1997.…”

-(Horizontal and vertical tree community structure in a lowland Atlantic Rain Forest, Southeastern Brazil). The horizontal and vertical tree community structure in a lowland Atlantic Rain Forest was investigated through a phytosociological survey in two 0.99 ha plots in the Intervales State Park, São Paulo State. All trees ≥ 5 cm diameter at breast height were recorded. 3,078 individuals belonging to 172 species were identified and recorded. The Shannon diversity index was H' = 3.85 nat.ind.-1 . The Myrtaceae family showed the greatest floristic richness (38 species) and the highest density (745 individuals) in the stand. Euterpe edulis Mart. had the highest importance value (33.98%) accounting for 21.8% of all individuals recorded. The quantitative similarity index was higher than the qualitative index, showing little structural variation between plots. However, the large number of uncommon species resulted in pronounced floristic differences. A detrended correspondence analysis (DCA) generated three arbitrary vertical strata. Stratum A (≥ 26 m), where Sloanea guianensis (Aubl.) Benth. and Virola bicuhyba (Schott. ex A.DC.) Warb. were predominant showed the lowest density. Stratum B (8 m < h < 26 m) had the greatest richness and diversity, and stratum C (≤ 8 m) showed the highest density. Euterpe edulis, Guapira opposita (Vell.) Reitz, Garcinia gardneriana (Planch. & Triana) Zappi, and Eugenia mosenii (Kausel) Sobral were abundant in strata B and C. The occurrence of strata in tropical forests is discussed and we recommend the use of DCA for others studies of the vertical distribution of tropical forest tree communities.Key words -diversity, multivariate analysis, phytosociology, tree stratification, tropical forest RESUMO -(Estruturas horizontal e vertical do componente arbóreo em floresta atlântica baixo-montana no sudeste do Brasil).A estrutura horizontal e vertical do componente arbóreo foi investigada em um trecho de Floresta Atlântica baixo-montana através de um levantamento fitossociológico em dois blocos amostrais de 0,99 ha cada no Parque Estadual Intervales. Todos os indivíduos com DAP ≥ 5 cm foram registrados. Foram amostrados 3.078 indivíduos distribuídos em 172 espécies. O índice de diversidade de Shannon foi de H' = 3,85 nat.ind.

“…Toucans, guans, several primates, and some carnivores, such as kinkajous, are good examples of specialized fruit eaters among vertebrates (Galetti and Pedroni, 1994;Peres, 1994;Galetti et al, 1997;JulienLaferrière, 1999;Da Silva and Tabarelli, 2000).…”

Our objective in this study was to examine the frugivory performed by the black-eared opossum, Didelphis aurita Wied-Neuwied, 1826, in an area of the coastal Atlantic Forest of southern Brazil, including differences between sexes, seasonal variation, and relationships to other sympatric marsupials. We collected 63 fecal samples from a trap grid over a six-month period and analyzed seed presence, seed number and richness, and diversity of fruit species in feces. Diversity of fruit items was estimated by the Shannon index. Results showed a high variability in fruit consumption along the seasons, but no sexual difference in consumption. Sympatric marsupial species, including D. aurita, showed substantial differences in frugivory which may be related to body size, space use and differences in the foraging behavior of such species.Key words: coexistence, food partitioning, fruit consumption, Neotropical marsupial ResumoFrugivoria pelo gambá-de-orelha-preta Didelphis aurita em Floresta Atlântica do sul do Brasil: o papel do sexo, estação do ano e espécies simpátricas. Nosso objetivo neste estudo foi examinar a frugivoria desempenhada pelo gambá-de-orelha-preta Didelphis aurita Wied-Neuwied, 1826 em uma área de floresta atlântica da costa do Brasil, incluindo diferenças entre sexos, variação sazonal e relações com espécies simpátricas. Nós coletamos 63 amostras fecais em uma grade num período de seis meses. Foram analisadas a presença e o número de sementes e a riqueza e a diversidade de frutos nas fezes. A diversidade de frutos nas fezes foi estimada pelo índice de Shannon. Os resultados mostraram alta variabilidade no consumo de espécies de frutos ao longo dos meses, mas não havendo diferenças entre os sexos. As espécies de marsupiais simpátricas, incluindo D. aurita, mostraram diferenças substanciais quanto à frugivoria as quais devem estar relacionadas a diferenças de tamanho do corpo, uso do espaço e comportamento de forrageio dessas espécies.

“…The region holds around 200 endemic bird species, many of which are believed to be threatened, primarily due to habitat alteration (Sick, 1993;Collar et al, 1994;Goerck, 1997) but, in some species, also through direct exploitation (Martuscelli, 1995;Galetti et al, 1997). Altogether, 21 parrot species occur in the region, of which seven are classi®ed as Endangered and two Vulnerable (Collar et al, 1994).…”

We estimated population sizes of parrots in a large (Sooretama/Linhares) and a small (Porto Seguro) lowland Atlantic forest reserve, and examined their habitat associations within the reserves, and their use of forest fragments. In Sooretama, most species had estimated populations between 1000 and 20,000 individuals, but in the smaller reserve population densities were low and all but one species had population estimates <500. Two Amazons, including the`Endangered' Amazona rhodocorytha, were strongly linked to primary forests whereas the`Vulnerable' Pyrrhura cruentata was associated with non-pristine forest. There was considerable movement of parrots between the Sooretama reserve and the surrounding country with Amazona species tending to¯y into the reserve during the mornings, and the macaw Propyrrhura maracana¯ying out. Other species, notably P. cruentata and P. leucotis, were never recorded away from the reserve. Most parrot populations in the region are likely to be small, and the substantial populations around Sooretama make this reserve a parrot stronghold. It is crucial that ®re, illegal logging and parrot capture are adequately controlled within Sooretama, and there is a strong argument for extending conservation management eorts to areas immediately outside the reserve. #
