3. The foraging behavior of the Large-headed Flatbill, Ramphotrigon megacephalum and the Dusky-tailed Flatbill, Ramphotrigon fuscicauda (Aves: Tyrannidae)
ABSTRACT Southwestern Amazonia has great bird diversity which includes birds specialized in bamboo forests. In this region, bamboo is considered a key element of the landscape. The objective of this study was to investigate and describe the foraging behavior of the Large-headed Flatbill, Ramphotrigon megacephalum (Swainson, 1835) and the Dusky-tailed Flatbil

4. cDNA cloning, Phylogenic Analysis and Gene Expression Pattern of Phenylalanine ammonia-lyase in Sugarcane (Saccharum officinarum L.)
The aim of the present study was to clone and characterize a full length cDNA of sugarcane (Saccharum officinarum) phenylalanine ammonia-lyase (SoPAL). Differential tissue expression pattern of the SoPAL transcript and its enzyme activity was also analyzed during the tillering stage of growth. The full-length of SoPAL cDNA was 2118 bp long and contained a pr

5. Composição e estrutura arbórea de um trecho de Floresta Ombrófila Densa Montana com taquaras na Mata Atlântica / Structure and floristic composition of a Montane Atlantic Rain Forest with bamboos in southeastern Brazil
Composta pela Floresta Ombrófila Densa, Floresta Ombrófila Mista, Floresta Estacional Semidecídua e ecossistemas associados, a Mata Atlântica (MA) sofreu inúmeras pressões que resultaram em redução de sua área. Estudos revelam que restam entre 11,4% e 16% da sua cobertura original e, devido a perda de mais de 70% de sua área somado a presença de e

7. Ecologia de Florestas Atlânticas com ocorrência do muriqui (Brachyteles spp.): diversidade, sucessão secundária e estrutura nutricional / Atlantic Forests ecology holding muriqui (Brachyteles spp.): diversity, secondary succession and nutritional structure
This study has three chapters which mainly aimed the understanding on the role of forests variables affecting distribution, abundance and range ecology of primates belonging to Brachyteles genera. The first chapter specifically aimed on characterization and comparisons of tree species diversity and secondary succession among three forests holding Brachyteles

9. EXPERIMENTAL ANALYSIS OF THE DYNAMIC PROPERTIES OF THE BAMBOOS OF THE SPECIES GUADUA, DENDEDROCALAMUS E AUREA / ANÁLISE EXPERIMENTAL DAS PROPRIEDADES DINÂMICAS DOS BAMBUS DAS ESPÉCIES GUADUA, DENDROCALAMUS E AUREA
The Bamboo is classidied as Bambusoideae or as Bambusaeceae that can be fond in abundance in tropical and sub-tropical contries. Studies had shown that the relation tensile stregth and specific weight of the bamboo is 2.73 greater that of the steel with the advantage to have a low consumption of energy and low cost in its production, besides being a renewabl

10. Ecologia de populações de Lytocaryum hoehnei (Burret) Toledo (Arecaceae) na Reserva Florestal do Morro Grande, Cotia, SP
The present study has investigated aspects of the natural history and ecology of palm Lytocaryum hoehnei. The palms were accompanied in three sites at the Reserva Florestal do Morro Grande, Cotia, SP, approximately 4 km apart from each other, during 2000, 2001, and 2002. Four ontogenetic stages were identified: 1) seedling: individuals with entire leaves, 2)

12. Floristica das fisionomias vegetacionais e estrutura da floresta alto-montana de Monte Verde, Serra da Mantiqueira, MG
The Atlantic Forest biome in the broad sense consists of a group of forest and grassland formations with different physiognomies, structures and floristic compositions. The Southeast of Brazil is one of the centres of diversity of this biome. In spite of numerous studies in the Atlantic Forest, there are still several poorly known physiognomies, such as the
