13. Resurrection of Anopheles goeldii from synonymy with Anopheles nuneztovari (Diptera, Culicidae) and a new record for Anopheles dunhami in the Brazilian Amazon
Nucleotide sequences of the internal transcribed spacer 2 (ITS2) rDNA and partial sequences of the cytochrome coxidase subunit I (COI) mtDNA and white gene nDNA were obtained from specimens of Anopheles nuneztovari A collected in Macapá (state of Amapá), Óbidos, Prainha and Almeirim (state of Pará), Itacoatiara and Parintins (state of Amazonas), Brazil,

14. Assombro de olhada de bicho : uma etnografia das concepções e ações em saúde entre ribeirinhos do baixo rio Tapajós, Pará Brasil.
Esta etnografia tem por objetivo compreender a lógica pela qual os ribeirinhos do baixo rio Tapajós, estado do Pará, Brasil, concebem as doenças e os tratamentos face a programas de saúde pública que procuram orientar essas concepções de acordo com uma lógica própria, e como respondem a isso segundo seu sistema cosmológico. A questão central cons

15. A beiradeira e o grilador: ocupação no oeste do Pará / The beiradeiraand the grilador: ocupation and conflict in West Pará
Like so many other Amazonian extractivists, the populations of Montanha and Mangabal trace their beginnings back to the first rubber cycle in the mid XIXth century when some of their ancestors installed themselves along the banks of the Upper Tapajos. Since then they have survived the debt bondage of the river trading system, the uncertain times that followe

16. Taxonomia de Psophia viridis (Aves: Gruiformes: Psophiidae) com base em caracteres morfológicos / Taxonomy of Psophia viridis (Aves: Gruiformes: Psophiidae) based on morphological characters
The dark-winged trumpeters, Psophia viridis (Gruiformes, Psophiidae) are endemic of the Brazilian Amazônia, featuring three recognizable subspecies: Psophia viridis viridis Spix, 1825; Psophia v. dextralis Conover, 1934, and Psophia v. obscura Pelzeln, 1857, as well as P. v. interjecta Griscom &Greenway, 1937, whose validity has been questioned. These taxa

17. URBAN MORPHOLOGY AND ATTRACTIVENESS OF TOURISM DESTINATIONS: the importance of image for understanding the tourism system of Vila de Alter do Chão (Santarém-PA) / MORFOLOGIA URBANA E ATRATIVIDADE DE DESTINAÇÕES TURÍSTICAS: a importância da imagem na compreensão do sistema turístico da Vila de Alter do Chão (Santarém-PA)
The sustainability of a tourist destination is intrinsically linked to the maintenance and/or improvement of the characteristics and attributes which attract the interest of the tourism market and of the tourist. One of these characteristics is the Urban Morphology, which combines the natural and built elements that make up the local space. This research, ca

18. Comparative study of human exposure to mercury in riverside communities in the Amazon region
Four populations in the Amazon area were selected for a comparative study of mercury-exposed and non-exposed populations: São Luiz do Tapajós, Barreiras, Panacauera, and Pindobal Grande. The highest mercury levels in human hair samples were found in São Luiz do Tapajós and Barreiras, greatly exceeding the limits established by the World Health Organizati

20. 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,

21. Aplicação de sensoriamento remoto no estudo da influência da dinâmica sazonal do Rio Amazonas sobre a morfologia dos sistemas lacustres / Use of remote sensing to study Amazon river seasonal dynamic on floodplain lake system morphology
Nesta pesquisa foi avaliado o efeito da dinâmica sazonal do nível d´água do rio Amazonas, sobre a caracterização morfológica dos sistemas lacustres. A área de estudo selecionada para esta pesquisa compreende a faixa da planície de inundação do Rio Amazonas, que se estende do rio Madeira, ao rio Tapajós. O presente trabalho teve como hipótese que

22. Análise da estrutura genética de populações e sistema reprodutivo de Oryza glumaepatula por meio de microssatélites / Genetic structure and mating system of Oryza glumaepatula steud. populations using microsatellite markers
Informations about genetic structure and breeding systems are little and poorly of natural O. glumaepatula populations. The objective of this study was the characterization of the genetic structure of 11 populations from Japura, Solimoes, Purus, Negro, Xingu and Tapajos rivers (from Amazon Hidrographic Basin) and from Paraguai and Taquari rivers (from Paragu

23. PREDIÇÃO DA CONCENTRAÇÃO DE MERCÚRIO EM TUCUNARÉ USANDO MODELOS DE BALANÇO DE MASSA E BIOENERGÉTICO / PREDICTING MERCURY CONCENTRATION IN TUCUNARÉ USING MASS BALANCE AND BIOENERGETICS
The mercury used in the artisanal mining (garimpo) of gold in the Amazon region is emitted to the atmosphere, soil and rivers. Once in the atmosphere, the metal is oxidized and immediately deposited. In the water, the transformation to methylmercury takes place mostly due to the action of microorganisms. The formation of methylmercury increases the dispersio

24. Cytogenetic damage related to low levels of methyl mercury contamination in the Brazilian Amazon
The mercury rejected in the water system, from mining operations and lixiviation of soils after deforestation, is considered to be the main contributors to the contamination of the ecosystem in the Amazon Basin. The objectives of the present study were to examine cytogenetic functions in peripheral lymphocytes within a population living on the banks of the T
