Litofácies e relações estratigráficas da formação Aquidauana no nordeste da Bacia do Paraná - São Sebastião do Paraíso (MG)

The Aquidauana Formation is characterized by sandstones of variable granulation, mudstones and diamectites abundant in clay, typical colors like brick red (vermelho tijolo) of glacial, fluvial and lacustrine origin. It’s chronostratigraphic equivalent to the Itarará group from the Neo Carboniferous age, that under the exploratory view, such units represent important intervals in the basin, occurring together with them minerals as well as energy resources as petroleum, underground water and coal – what requires a great paleogeography and stratigraphy knowledge for its exploration. By gathering information from the columnar sections of the area, it was possible to characterize the sedimentary facies, the stacking pattern as well as the association. It was also made an attempt of stratigraphic correlation, which showed great difficulties since glacial environments present a great lateral discontinuity of the facies besides the complex relationship process of formation. As a result, it was obtained 8 sedimentary facies, the lateral and vertical relations and genesis process. It is proposed that the sedimentary environment in the study area is the fluvio glacial, characterized by alluvial systems formed by defrosted water which transport the sediments that are deposited in plains in front of the glacier (distal outwash). Petrographic thin section analysis showed that the transportation process was ineffective. The grains present punctual to lobular contacts, characterizing good porosity and permeability to the rock, varying these qualities according to more or less existence of matrix. The presence of Iron Oxide deposited between the recrystallization border and feldspathic mineral indicates that this rock has possibly presented a primary rubefaction, intensified by alkaline fluid percolation

Análise de microclima e cobertura de dossel em áreas refloestadas nas estações de chuva e seca no Reservatório de Capivara, Paraná

O estudo das analises microclimáticas foi desenvolvido no Laboratório de Biodiversidade e Restauração de Ecossistemas da Universidade Estadual de Londrina, Paraná, e foramselecionados cinco talhões de reflorestamento de diferentes idades ao longo do Reservatório de Capivara, Paraná. Em cada talhãoforam registrados dados de temperatura, umidade do ar e cobertura de dossel,nos meses de março e agosto, período de chuva (verão) e de seca (inverno), respectivamente.Os dados foram comparados em busca de uma relação entre cobertura de dossel e microclima nos talhões de diferentes idades e nas diferentes estações. As amostragens demonstram que há uma diferença significativa entre as estações considerando as variáveis estudadas e que as variações estruturais do reflorestamento e a arquitetura das diferentes espécies que a compõem resultam em variações na cobertura do dossel, que por sua vez implicam em variações microclimáticas importantes para o processo de regeneração

Análise de dados pedogeoquímicos de multielementos visando o refinamento de mapeamento geológico de detalhe em alvos de Pb-Zn nos municípios de Adrianópolis, Cerro Azul e Tunas do Paraná (Vale do Ribeira, PR)

The main rock types are present metasedimentary rocks of low to medium grade metamorphic, interspersed the amphibolites ortoderivados, both belonging to the Complex Perau, gneisses and migmatitic Complex. Applied to the geochemical data descriptive statistical techniques (variogram, kriging and histogram). From the correlation between the distributions of elements with the geological data, we could assess the potential of the proposed methodology.

Proposta de traçado de alcoolduto ligando a hidrovia Tietê Paraná à refinaria do planalto paulista com uso de avaliação multicritérios e geotecnologias

From the beginning of the century, with the advent of the flex fuel car, successor fluctuations in oil prices and the rise of awareness of the impending shortage of fossil fuels, the alcohol sector begins to reappear in the panorama of national economy making Brasill reaches the point of becoming a leading exporter of this product. Ethanol assumed the role of such importance in Brazilian exports, which Petrobras through the Growth Acceleration Program (PAC) has made investments in the Brazilian pipeline network to better ensure the production of ethanol to major ports. The means of transport in pipelines are safe and inexpensive, but require careful evaluation in its implementation, they may lead to negative social and environmental impacts. Thus, the purpose of this project is to propose the best route for an ethanol pipeline connectin the Tietê-Paraná, leaving the municipality of Santa Maria da Serra (SP), to the Planalto Paulista Refinery (REPLAN), located in Paulinia (SP), belonging to the passage of ethanol export corridor, currently under revelopment. The technique used for the development of the stroke is the association of multicriteria evaluation, the geographical information system (SIG) and geotechnologies. This study presented three possible layouts for the ethanol pipeline, highlighting the best option, in addition, demonstrated the suitability of the area to receive projects of similar nature to a pipeline

Assembleias fitoplanctônicas no gradiente longitudinal barragem-jusante do reservatório de Itaipu, rio Paraná (Brasil/Paraguai)

The freshwater phytoplankton, responsible for a significant part of primary production in rivers and lakes, is of great importance for matter and energy available to other trophic levels of structuring aquatic food chains. In recent decades, the construction of dams, especially for the generation of electricity, produced changes not only in physical and chemical characteristics of rivers, but also in biocoenosis of these ecosystems. Thus, research is needed to expand the basic knowledge about these environments and subsidize actions appropriate conservation and management. Considering that lotic environments are relatively little studied, and the river-reservoir interaction, the work aims to analyze the limnological conditions and assemblies phytoplankton along the gradient established by the Itaipu reservoir and downstream stretch of the Paraná River. During two periods of the year, winter and summer, we analyzed nine sampling stations: one in lentic environment (the dam), six on the Parana River (each 5 km), at the mouth of a river Monday and another at the mouth of the Iguazu river. The phytoplankton community was composed of 315 taxa, with the class Bacillariophyceae most specious. At every point the richness was higher in summer and with a longitudinal trend in the increasing points after falling after the dam and the contribution of the tributaries. The number of taxa common to the three rivers was low in both study periods. The higher taxa can be explained by the variety of environments sampled, different residence times of water and nutrient concentrations, whereas the rivers Iguazu and Monday suffer high human influence. The greater abundance of organisms in the dam, in both periods, it should be the class Cryptophyceae contributing over 75% of total phytoplankton in point. In cluster analysis (composition and abundance)...(Complete abstract click electronic access below)

Aspectos reprodutivos de três espécies de Curimatidae (Characiformes) em um reservatório do Rio Mogi Guaçu, bacia do Alto Rio Paraná, São Paulo, Brasil

Os curimatídeos são espécies comuns em ambientes lênticos represados, artificialmente construídos. Estudar o ciclo reprodutivo de uma espécie é fundamental para a compreensão da biologia reprodutiva da população em seu ambiente. Por isso, o presente estudo analisou os aspectos da biologia reprodutiva dos sagüirus Cyphocharax modestus, C. cf. nagelii e Steindachnerina insculpta (Curimatidae), no reservatório da pequena central hidrelétrica Mogi Guaçu, município de Mogi Guaçu, estado de São Paulo. Os exemplares foram coletados bimensalmente entre agosto de 2005 e julho de 2006 com o auxílio de redes de emalhar (malhas 1,0 a 5,0 cm entre nós adjacentes), totalizando seis amostras. No total, foram analisados 777 exemplares, sendo 525 de C. modestus, 82 de C.cf. nagelii e 170 de S. insculpta. A dinâmica reprodutiva foi analisada considerando-se os períodos seco e chuvoso. A fecundidade foi estimada de acordo com o método volumétrico a partir da análise de 168 pares de ovários maduros, sendo 121 de C. modestus, 18 de C. cf nagelii e 29 de S. insculpta. Também foram estimadas as relações gonadossomáticas médias e as correlações do número total de ovócitos em relação ao peso e ao comprimento para cada uma das três espécies. Os resultados encontrados apontaram para desova total (sincrônica em dois grupos) para as três espécies. O número médio de ovócitos foi de 15.309 a 28.825 para C. modestus, 29.031 para C. cf. nagelii e 27.206 para S. insculpta.

Quimioestratigrafia do vulcanismo ácido mesozóico da província magmática do Paraná: porção SE do estado de Santa Catarina

The Mesozoic acid volcanism of the Paraná-Etendeka Province can be considered as one of the biggest events of its kind in the Earth's surface, and its study have attracted special interest in characterizing the end of magmatism that preceded the rupture process and the formation of continental Africa and South America Although significant, the acid volcanism featuring Members Chapecó Palmas and Serra Geral Formation represents only 2.5% of the total generated by the magmatic rocks and perhaps therefore the existing literature on these rocks is well less significant than that on the basalts. However, there are still aspects still unclear about the origin and evolution of these rocks in relation to the associated basalts. Thus, two profiles were selected, called RA and TA, which be a systematic collection of samples from the base where the Botucatu Formation sandstones occur at the top, where they observe Palmas acid rock type. These samples should be analyzed for major, minor and trace elements and treated in specific diagrams to define the vertical variation lithochemistry and their possible relationships with the associated basalts

Monitoramento espacial e análise das características climáticas na influência sobre a cultura de soja no estado do Paraná

In the past years, soya has increased itself as the mean agro export culture in Brazil, encouraging the expansion of its agricultural frontier throughout the country. Brazil is the second biggest soya producer around the world, with a 59,8 million ton production in 2008, according to the Instituto Brasileiro de Geografia e Estatística (IBGE), only behind United States. Around the country, the four leading producer states are Mato Grosso, Paraná, Rio Grande do Sul e Goiás. Therefore, geotechnologies may be used to monitor use and soil occupation in various analyzes periods. In this review, the tools are important to illustrate the soya production areas and also the weather behavior around its production evolution in the territory through the years. Its utilization can contribute to the evolution and optimization around real time monitoring of the Agricola cultures, without being necessary to be in the area with a low financial cost. Generally, this information is strongly important for decision makers in both government and private sector, as soon as the achievement information regards the quantification of area, yield and development of agricultural crops are essential to the economic behavior of culture during the season and even beyond. By obtaining data regarding climate crops 2008/09 and 2009/10, held the climatic water balance calculation based on the dynamics of water storage in soil temperature and precipitation data, interpolation of the data through the interpolator (IDW) that generated thematic precipitation maps. Overall, the use of geotechnology to monitor agricultural areas, can strongly contribute to this monitoring, generating raw material for further analysis at low cost

Amphibians of grasslands in the state of Paraná, southern Brazil (Campos Sulinos)

Amphibian conservation depends on knowledge about species composition and distribution. This emphasizes the need for inventories, especially in poorly sampled areas. This is the case of Southern grasslands (Campos Sulinos) associated with Araucaria forest in the state of Paraná, southern Brazil. We sampled amphibians in 105 environments from 2004 to 2013 using transect sampling, active search and surveys at breeding sites. We found 61 anuran species and two caecilians. This is the first comprehensive list of amphibian species inhabiting grasslands in Paraná. This landscape deserves high conservation priority before these natural grasslands vanish.

Desenvolvimento local e a construção de uma nova territorialidade: a implantação do Programa Territórios da Cidadania no norte pioneiro do Paraná

The territorial approach of development took an important place in the public politics of the State, also guiding the actions originated from different organizations of the society. The territorial focus, infl uenced by the analysis related to the industrial districts, is highlighted as a specifi c form to dealing with process and situations spatially delimited. In Brazil, the Secretary of Territorial Development, linked to the Ministry of Agrarian Development, since 2003, has adopted it strategically through the Programa Nacional de Desenvolvimento Sustentável dos Territórios Rurais (PRONAT). In 2008, had occurs the implantation of the Programa Territórios da Cidadania, a part of the PRONAT and of the rural development politic directed to the dynamization of the depressed territories constituted by small counties that cover rural and urban areas and activities, overcoming the focus on the rural world. The analysis of the assumptions underlying to the adoption of this strategy on the politic of the rural development in Brazil made through the study of the constitution of the Território Integração Norte Pioneiro (PR), which indicates that the focus of this politic falls more on the effectiveness of the decentralization than the concretization, and implementation, of the social management.

Hidrovia e desenvolvimento regional: estudo dos projetos de desenvolvimento dos vales do Tietê e Paraná no Estado de São Paulo

The interest in conducting the study relies on the possibility that it may contribute to the debate on the reshaping of public policy and style necessary to establish a new pattern of regional development in the country"

Variação sazonal das variáveis físicas e químicas em riachos de duas bacias da região centro-sul do estado do Paraná, sul do Brasil

The present study was developed in two streams from the two different drainage basins located in the mid-southern region of Paraná state. In each stream were evaluated some physical and chemical parameters in open (without streamside vegetation) and shaded (with streamside vegetation) segments. Monthly samplings were carried out from January to December 2007. The following limnological parameters were measured: water temperature, specific conductance, oxygen saturation, pH, turbidity and current velocity. In the same stream were not observed differences among segments from the drainage basins, and nominal values and seasonal pattern have been very similar between open and shaded ambient. A Principal Component Analysis (PCA) showed small divergence between streams and segments, with separation of groups with base sampling dates. The results suggest that the region is homogeneous according to physical and chemical water conditions, therefore, stronger influenced for time factor, and diverging seasonal periods associated a climatic region condition.
