A cunha do ciclo de fácies do Grupo Guatá (Eopermiano) na margem sub-aflorante do norte paranaense

A wedge facies cycle it‟s a body of sedimentary rock, bounded above and below by unconformity and which represents a transgressive-regressive cycle of deposition. This cycle is formed by the following succession of facies: non-marine (N), transitional-coarse texture, and marine-fine texture; The objective of this study have been members of the sandstones and Triumph Siderópolis, seconded by rare calcareous sandstones and very thin limb Paraguaçu. Through analysis of facies in wells testified by CPRM, it was possible to group on facies successions and set the standard stacking. The Triunfo Member consists of three cycles of facies, lithology whose standard indicates a vertical arrangement ''type'' tuning up, other words, a component sandy bottom in the form of '' box'', followed by components sandy-clayey and clayey-carbonaceous (1st and 2nd cycle) and / or shale and limestone (3rd cycle), represented by the base member Paraguaçu. The first cycle only occurs on NF-5 wells and NF-6 in the form of Onlap channel dug in post-Itararé group. The cycle II also reaches wells NF-4 and NF-3 to the north, while the cycle III reaches the southern area, well NF-9. The member Paraguaçu, well PP-25 is predominantly clay-síltico, also stand out limestones and sandstones. The limestones are not coastal marine organisms probably connected with the algae and cyanobacteria, the sandstones are fine-textured, very thin and coastal deposition environment. The member Siderópolis, well NF-2 consists of a sandstone fluvial-estuarine deployed in the valley section, and succeeded by sandstones and siltstones bioturbed, they have linked the transgression of the Fm.

Caracterização litogeoquímica dos basaltos do município de Monções -SP

The paper deals with the petrographic and geochemical investigation of basalt flows present in a gravel quarry in the town of Monções in northwestern São Paulo State, members of the Serra Geral Formation of the Paraná Basin. Were collected 11 samples from different horizons within a topographic vertical profile with an average of 18 meters in height. The samples were subjected to macroscopic and microscopic petrographic and chemical major, minor and trace. The results indicated that it is tholeiitic basalts with dense fine grained average. Petrographic analyzes show that basalts studied are basically constituted by plagioclase (between 33 and 49%), labradorite and clinopyroxenes (between 29 and 46%) represented by the subordinate pigeonite and augite, having as accessories opaque (between 3 and 15% ), olivine (<2%), apatite and zircon as dashes. The secondary minerals correspond to cloropheite, chlorite, serpentine, epidote, albite and iron oxides and hydroxy as well as bowlingit of clay, nontronite, and celadonite. The basalts are kind of high-titanium (Hti)> 1.8% TiO2, and apparently belong to the Pitanga magma-type. The geochemical analyzes proved unsatisfactory for the determination of a probable lithogeochemistry differentiation within the vertical stroke for generating multiple data correlation or no immediately discernible trends

Efeito da matriz na capacidade de aves flrestais moverem-se na paisagem

Matrix can be defined as a portion of the landscape, that somewhere in time suffered intense human disturbance, such as decreasing of native vegetation. The matrix surrounding the forest fragments may create a certain resistance to the movements of individuals (RICKETTS, 2001). The Atlantic rainforest present in the Corumbataí river basin lost about 89% of its original vegetation, leading to a highly fragmented landscape (VALENTE e VETTORAZZI, 2005). In this context, this study aimed to evaluate the effect of the matrix and the characteristic capacity of two forest birds, Dysithamnus mentalis and Basileuterus flaveolus, moving around the landscape. With this aim, six fragments were selected, three with sugar cane matrix, three with Eucalyptus sp. matrix. The methodology utilized to evaluate the response of the birds was playback technique. First the vocalizations were carried out at the forest matrix boundary, in the edge, attracting individuals to the matrix. As the responses were generated, the playback was moved increasingly inside the matrix, observing the distances traveled by the species. The control trials were conducted inside the fragments, the playback was played at the edge and as the responses were observed, the vocalizations were carried out inside the fragment until the moment that individuals ceased answers. It could be observed that for individuals of D. mentalis the matrix generated a high resistance, because no individual entered the matrix. For B. flaveolus the average distance traveled in both matrices was 70 meters, indicating statistically high resistance of the sugar cane matrix and Eucalyptus sp. Considering the characteristics of different matrices, it was found that both matrices generate similar resistance in the movement of these species

Diversidade gênica no gênero Astyanax (Teleostei : Characidae) através da análise de PCR-RFLP de DNA mitocondrial

O gênero Astyanax é um dos mais abundantes e diversificados da família Characidae (subfamília Tetragonopterinae), com mais de 100 espécies nominais, estando amplamente distribuído na bacia do Alto rio Paraná. Esse gênero é caracterizado pela similaridade quanto à forma do corpo, além da alta variabilidade citogenética intra e interpopulações, sendo comum a ocorrência de espécies crípticas ou complexos de espécies. Devido à escassez de dados sobre genética molecular referentes a esse gênero, e a dificuldade na identificação taxonômica, fazse necessário um estudo utilizando marcadores moleculares que visem desenvolver métodos rápidos e eficientes para caracterização de espécies de Astyanax com base em análises de DNA. Em vista dessa necessidade, o presente trabalho teve como objetivo avaliar a eficiência da técnica de PCR-RFLP do gene mitocondrial Citocromo b na identificação e caracterização da variabilidade genética de cinco espécies do gênero Astyanax que ocorrem na bacia do Alto rio Paraná. O mtDNA das espécies alvo foi totalmente amplificado, num total de cerca de 1140 pares de bases (pb). As análises foram obtidas através dos haplótipos gerados com a digestão por três enzimas de restrição que clivam estes genes, sendo estas ALUI, BAMHI, e HPAII. Foram analisadas 2 populações de Astyanax paranae, A. altiparanae, A. fasciatus, A. bockmanni, e uma população de A. biotae, com amostragens variando entre 5 e 10 indivíduos de cada população. Como grupo externo foram analisadas duas populações de Astyanax ribeirae da bacia hidrográfica do rio Ribeira de Iguape. Ao final do trabalho foi possível a identificação de 4 das 6 espécies analisadas, sendo que as espécies mais divergentes são A. altiparanae e A. ribeirae, as espécies A. paranae + A. bockmanni e A. fasciatus + A. ribeirae são as mais fortemente relacionadas...(Resumo completo, clicar acesso eletrônico abaixo)

Estudo da dinâmica climática e sua influência na qualidade da água de reservatórios urbanos

The present study sought to develop a methodology to analyze the water quality based on concepts and methods of climate and climatology respectively. In this way, it was tried to relate techniques and methodologies hydro and limno-meteorological with a rhythmic analysis technique developed within the Brazilian geographical climatology to assess and analyze the blooms of cyanobacteria, the main index of water quality found in reservoirs of “Alto Tietê” Basin and consequently the Metropolitan Region of São Paulo, an area of high environmental complexity due to its high degree of development and high population density. The meteorological data used to develop the study were collected from the meteorological station of the IAG / USP and the limnological data were collected from the Hydrological Monitoring System implemented by SABESP in Billings and Guarapiranga reservoirs as well as data laboratory of the same entity. The results obtained by the rhythmic and integrated analyze showed that the process of blooms of cyanobacteria is dependent not only on one specific factor, but a combination of meteorological factors that may disrupt the stability of reservoir and which can, during the stabilization process, provides the necessary conditions to the development of cyanobacteria. It was also shown by the results that the pace of Atlantic Polar Front Entrance during the winter in São Paulo, is a limiting factor to the growth of cyanobacteria due to their high frequency, keeping the reservoir balance throughout the period. Furthermore, another importance of this study is the possibility of prevention and forecasting periods which are inappropriate for the use of these reservoirs mainly for recreational activities
