13. Camu-camu arbustivo (Myrciaria dubia) e camu-camu arbóreo (M. floribunda): enxertia intraespecífica e interespecífica
The camu-camu (Myrciaria dubia (H.B.K.) McVaugh) is a shrubby indigenous fruit species found in the floodplains of Amazonia. The species is commonly propagated by seeds, and consequently shows considerable variation in age of bearing, production cycle, fruit yields and Vitamin C contents. Myrciaria floribunda (West ex Willd.) O. Berg is a small tree that occ

14. A utilização de tecnologias digitais de geoprocessamento na identificação de unidades de paisagem na bacia hidrográfica do rio Iguaçu-Sarapuí (RJ) / The use of gis technology in identification of landscape units in the Iguaçu river
The Iguaçu River Falls is part of the river basin of Guanabara Bay. Its drainage area, with about 726 km2, corresponds to approximately 20% of the total area of contribution to the Bay, the order of 4600 km2. The municipalities covered by the Iguaçu River basin are: Nova Iguaçu, Duque de Caxias, Belford Roxo, São João de Meriti, Nilópolis, mosque and a

15. Seasonal variation on isotopic and chemical composition of the water in Lago Grande de Curuai floodplain, Brazil / Variação sazonal na composição isotópica e química da água na Planície de Inundação do Lago Grande de Curuai, (PA)
O entendimento da dinâmica biogeoquímica é um ponto central na tentativa de, racionalmente, manejar recursos e minimizar os impactos gerados por atividades antrópicas nos sistemas aquáticos amazônicos, especialmente devido à importância dessa região no ciclo global do carbono. O presente estudo pretende contribuir com esta temática avaliando a comp

16. O QuaternÃrio do Parque Nacional Serra da Capivara, PiauÃ, Brasil: morfoestratigrafia, sedimentologia, geocronologia e paleoambientes
The Serra da Capivara National Park is internationally recognized because it houses the most important concentration of rock paintings and archeological sites in the American continent. Vestiges of human occupation are distributed in 1.000 archeological sites many times located in Quaternary sediments, with few researches realized until the moment. The objec

17. Human occupation and conservation of the Serra do Divisor National Park, Alto Jurua-Acre / Ocupação humana e a conservação do Parque Nacional da Serra do Divisor (PNSD), Alto Jurua-AC
The Serra do Divisor National Park (PNSD) is a strict use protected area located in state of Acre, in the border with Peru. The National Park was created in 1989 with an area of 843.012 ha, the equivalent of 5,5% of total area of the state. According to the management plan, the National Park had, in 1998, 3.115 inhabitants, grouped in 522 families inside the

18. Study of amazon floodplain water composition using hyperion/EO-1 and field reflectance data for the comprehension of temporal variability of optically active constituents / Estudo da composição das águas da planície amazônica por meio de dados de reflectância do sensor hyperion/EO-1 e de espectrômetro de campo visando a compreensão da variação temporal dos seus constituintes opticamente ativos
Two methodological approaches were evaluated to study the reflectance of optically active constituents using hyperspectral imagery of EO-1 Hyperion orbital sensor: a) Linear Spectral Mixture Model; and b) derivative analysis. Two Hyperion images acquired over an area located upstream of the confluence between the Amazon and the Tapajós rivers were analysed,

19. Artrópodos associados à copa de Attalea phalerata Mart. (Arecaceae), na região do Pantanal de Poconé, Mato Grosso, Brasil
Six individuals of the palm A. phalerata, in Poconé floodplains of Mato Grosso, were sprayed with a synthetic pyrethroid (0.25% concentration) in order to study the biomass, diversity, and richness of the canopy arthropods. A total of 17,188 (238.7±80.6 ind./m²) arthropods belonging to 22 Orders, was collected in a 72 m² funnel area. Two hours after spra

20. INFLUÊNCIA DO PULSO DE INUNDAÇÃO NA COMPOSIÇÃO ISOTÓPICA (d13C E d15N) DAS FONTES PRIMÁRIAS DE ENERGIA NA PLANÍCIE DE INUNDAÇÃO DO RIO PARAGUAI (PANTANAL MS) / SEASONAL PATTERN DETERMINING PRIMARY ENERGY SOURCES d13C AND d15N IN THE PARAGUAY RIVER FLOODPLAIN TROPHIC WEB, PANTANAL WETLAND - BRAZIL
The food web of the Pantanal wetland in Brazil was investigated during a complete hydrologic cycle (1998-99) using a multiple stable isotope approach (d13C and d15N) with the goal of identifying the primary carbon sources, which drive the system energy flux. The sampling was done in a representative marginal lake (Baía do Castelo) of Paraguay River floodpla
