“…Plateau forests are a transitional ecosystem, bordered by tropical evergreen broadleaf forest to the east, which originally covered the Atlantic coastline, and the dry cerrado vegetation to the north and west (Ab’Saber, 1977). Cerrado is a tall dense semideciduous xeromorphic savanna vegetation (Baitello et al ., 1988). The region is characterized by a pronounced dry season with annual precipitation averaging between 1200 and 1260 mm of which 30 per cent falls between April and September (Valladares‐Padua, 1987, 1993).…”

This paper evaluates the ecological consequences of hunting by comparing mammalian densities, biomass, relative energy consumption and community structure between sites with different levels of hunting pressure. Hunting is carried out mainly by colonists who farm on the edge of Atlantic forest fragments in the State of São Paulo, Brazil. Mammals were studied over a period of 18 months, along 2287 km of line transects. Transects were distributed among two protected sites, one slightly hunted site and two heavily hunted sites. Tapirs, the two peccary species, brocket deer, armadillos and agoutis are preferred by hunters in the region. Primates are not hunted in the region. Hunting has affected community structure, with ungulates dominating mammalian biomass at protected sites and primates dominating at hunted sites. This has caused an ecological inversion in the hunted areas of the Atlantic forests. In Amazonian regions of the Neotropics hunting is more evenly distributed among primates, large rodents, and ungulates and has resulted in an opposite inversion, with hunted sites having lower primate biomass. Atlantic forests are very susceptible to the possible ecological imbalances induced by hunting by humans, and this must be considered for management and conservation programmes.

This paper evaluates the ecological consequences of hunting by comparing mammalian densities, biomass, relative energy consumption and community structure between sites with different levels of hunting pressure. Hunting is carried out mainly by colonists who farm on the edge of Atlantic forest fragments in the State of Sao Paulo, Brazil. Mammals were studied over a period of 18 months, along 2287 km of line transects. Transects were distributed among two protected sites, one slightly hunted site and two heavily hunted sites. Tapirs, the two peccary species, brocket deer, armadillos and agoutis are preferred by hunters in the region. Primates are not hunted in the region. Hunting has affected community structure, with ungulates domin-ating mammalian biomass at protected sites and primates dominating at hunted sites. This has caused an ecological inversion in the hunted areas of the Atlantic forests. In Amazonian regions of the Neotropics hunting is more evenly distributed among primates, large rodents, and ungulates and has resulted in an opposite inversion, with hunted sites having lower primate biomass.

-(Structure and diversity of the arboreal component of the forest at Caetetus Ecological Station, Gália, SP). Phytosociology of distinct tree strata in tropical forests can be an important tool to understand community dynamics. The arboreal community of an area (6,000 m 2 ) of mature forest was surveyed at the Caetetus Ecological Station, Gália, São Paulo State, Brazil. This protected area has one of the last significant forest remnants in Western São Paulo State, covering an area of 2,178.84 ha in a region where coffee plantation and pasture are dominant. Although the fragment has been protected against fire and exploitation for many years, there are visible edge effects. The sampling area in this study was intended to be representative of the original primary forest, free from edge effects. The arboreal community was divided into three strata: DBH equal to or higher than 5 cm (upper), DBH between 1 and 5 cm (intermediate) and DBH below 1 cm (lower). In each layer, 60 permanent plots, with different sizes were installed, being: 10 x 10 m (upper layer); 10 x 2 m (intermediate layer) and 2 x 2 m (lower layer). The upper stratum had 1,080 ind.ha -1 , 62 species (28 families), being the most important (decreasing order): Metrodorea nigra, Savia dictyocarpa, Ocotea indecora, Aspidosperma polyneuron and Trichilia catigua. The intermediate stratum had 3,525 ind.ha -1 , 30 species (17 families), being the most important: Metrodorea nigra, Actinostemon concolor, Trichilia catigua, Aspidosperma polyneuron and Trichilia claussenii. The density in the lower stratum was 28,875 ind.ha -1 , from 37 species (19 families), being the most abundant, in decreasing relative density: Metrodorea nigra, Actinostemon concolor, Trichilia catigua, Aspidosperma polyneuron and Eugenia blastantha. Some of the species of the upper stratum was absent in the other strata, especially heliophytes, typical from early sucessional stages (e.g. Croton floribundus). Other species had decreasing importance values from the upper to the lower stratum (e.g. Savia dictyocarpa and Ocotea indecora). There were species whose seeds germinated but plants did not grow in the shade (e.g. Cariniana estrellensis). Finally, there was a group of species, typical from late successional stages, that had similar relative density in all strata, e.g. Metrodorea nigra and Aspidosperma polyneuron.RESUMO -(Estrutura e diversidade do componente arbóreo da floresta na Estação Ecológica dos Caetetus, Gália, SP). O estudo fitossociológico, se realizado em diferentes estratos verticais da floresta, fornece dados de grande valia para a compreensão da dinâmica da comunidade. Efetuou-se levantamento das espécies arbóreas presentes em diferentes estratos, em área de 6.000 m 2 de floresta madura, na Estação Ecológica dos Caetetus, Gália, SP. Foram utilizadas 60 parcelas de 10 x 10 m, para indivíduos com diâmetro do caule a 1,30 m acima do nível do solo (DAP) a partir de 5 cm (estrato superior); 10 x 2 m, para indivíduos com DAP entre 1 e 5 cm (estrato intermediário) e 60 sub...
