Estimativa da diversidade genética de Queixadas (Tayassu pecari) da região do Taboco (Corguinho, MS)

The Brazilian fauna has been constantly threatened by deforestation and forest fragmentation. As a result, many populations become isolated and small which negatively impacts their genetic diversity, putting them at a higher risk of extinction than large and stable populations. The aim of this work was to estimate the genetic diversity of white-lipped peccaries (Tayassu pecari) in the region of Taboco (Corguinho, MS), a fragmented area; and to compare these estimates with that obtained previously for two populations from Brazilian Pantanal, which is considered a relatively well-preserved biome and where the species is not threatened. A total of 18 blood and 72 hair samples of white-lipped peccaries had their DNA extracted and amplified for five polymorphic microsatellite loci. With the individuals identified, genetic diversity indicators (such as number of alleles, allelic richness, expected end and observed) and the inbreeding coefficient FIS were calculated. In addition, to verify if the population suffered a recent population bottleneck, we used the tests implemented in the program Bottleneck. The population of Taboco showed no evidence of recent population bottleneck (p > 0.05) or inbreeding (FIS = 0.008; p > 0.022). In addition, the levels of genetic diversity in this population (mean number of alleles = 2.60; mean allelic richness = 2.56 mean observed and expected heterozygosities = 0.45 and 0.47, respectively) were statistically similar to those found previously for the two populations from Pantanal (p > 0,05); although the region of Taboco is more impacted than the Pantanal. Even though we showed no evidence of loss of genetic diversity, it does not mean that the population is not suffering with fragmentation; but that there was not sufficient time to evidence the genetic changes. In addition, may be occurring gene flow with populations of nearby fragments, which is maintaining... (Complete abstract click electronic access below)

Datação por U-Pb em rutilos de rochas de metamorfismo de alta pressão do grupo Araxá na região de São Sebastião do Paraíso - MG

Although several studies of Araxá Group in the region of Passos, just a few works deal with the age of metamorphism of this group. The current work aims to determine the cooling age of these rocks by in situ U-Pb dating in rutiles. Interestingly, the region of São Sebastião do Paraíso shows a condensed lithostratigraphic column from the Passos Nappe and exposes the higher metamorphic grade rocks described for this unit. The use of rutile as a geochronometer is based on its ability to incorporate U in its structure, facilitating the calculation of the age of the isotope ratio by U-Pb. Furthermore, the use of in situ dating technique with Laser Ablation has been a reliable and advantageous study because the analysis are punctual, and do not destroy the whole sample to be analyzed. The analyses of this work were made at the University of Gothenburg - Sweden and obtained 238U/206Pb ages between 608-566 ± 10 Ma and 235U/207Pb between 627-572 ± 10 Ma, showing that these ages are concordant with the literature in the area and are interpreted as the cooling age of metamorphism

Estudo do metamorfismo de rochas de alto grau do grupo Araxá na região de São Sebastião do Paraíso - MG

This study focuses on metasedimentary rocks from the Passos Nappe in São Sebastião do Paraíso, southern Minas Gerais, Brazil. These rocks belong to the Internal Domain (Araxa Group) of the Southern Brasilia Belt, a Neproterozoic orogenic belt associated to the formation of the Gondwana Supercontinent. Rocks from the studied area are characterized by an inverted metamorphic gradient. Previously calculated metamorphic conditions show an increasing from geenschist facies at the base (450°C, 6 kbar), to upper amphibolite facies (750°C, 11 Kbar) at the top of the sequence. However, most of these estimates are based on Fe-Mg exchange thermometers and peak temperatures may be underestimated due to Fe-Mg exchange from cooling after peak metamorphism. In this study, we present new PT results for these rocks, based on metamorphic mineral assemblage LA-ICP-MS analyses. In the studied area, rocks from the top of the sequence have a typical granulite facies mineral assemblage: Grt+Ky+Kfs+/-Pl+liq. These rocks lack muscovite and have only minor amounts of Ti-rich, dark brown biotite. In a simplified NaKFMASH system the stability field for this mineral assemblage is bounded by the reactions Sil = Ky on the low pressure side, Ms+Ab = Ky+Kfs+liq on the low temperature side and for high-Mg bulk compositions Bt + Grt = Opx + Ky + liq on the high-temperature side. Minimum temperatures (considering post-peak reequilibration) of ca. 750°C are obtained by Fe/(Fe+Mg) values of 0.7 in garnets from a Grt+Ky+Kfs bearing sample. LA-ICP-MS results obtained for three samples show that rutiles included in garnets have up to 1847 ppm of Zr, which would translate into temperatures up to 830°C for a pressure between 12 to 15 kbar. Also for retroeclogite sample, the results indicate the contents of Zr in the garnet 537 ppm at a temperature of 708 ° C. It is noteworthy that several occurrences of retroeclogites occur in the upper part of the sequence and pressures...

Experimentação no ensino de física: um estudo escolas estaduais na região de São José dos Campos

This work presents the results of a study on the use of experimentation in physics teaching, presenting a survey on the use of this strategy in public high schools in the region of São José dos Campos. Data collection was carried out in schools by means of questionnaires prepared for physics teachers and students from three grades of high school. Data were obtained in eighteen schools distributed in the city of São José dos Campos (two in the central region, in the west, three on the east side, seven in the north and five in the south), a school in the district of Sao Francisco Xavier and a school in the town of Monteiro Lobato. Thus, data from 20 schools, 610 students and 20 teachers were analyzed. Among the main results, we highlight that over 80% of the students said that there is no physics lab at the school where they study, and less than 1% declares that uses laboratory weekly. We note that there is a laboratory in 25% of the schools in the northern region and 10% or less of the other schools. According to the students the proposition of the experimental activities by teachers is rare - only three schools in East Side the options sometimes and always exceeded the number of responses experimental activities are never proposed. We had 60% of the teachers who reported using the curriculum of the state of São Paulo to propose activities to students, and half of the teachers said they did not have classes experimental physics classes in initial training or had them in sufficient quantity to support the use of this feature in practice

Memória ambiental, cultural e turismo no vale histórico do Rio Paraíba do Sul: design de uma pesquisa

This text is aimed at disseminating cultural and environmental wealth of a region little known of major tour operators - which is strongly marked by historical traditions, in a bucolic rural still and by the hospitality of its residents. The Historic Valley of Rio Paraíba do Sul, although located in the Rio - Sao Paulo road lives in the shadow of the remarkable progress of the industrial cities in the main Valley. This paper presents results of research that deepened the knowledge of this region, with notable findings from the standpoint of culture and tourism, regional and national history. Isolated by considerable geographical barriers, this region has two aspects: the rebirth of nature after the decline of coffee plantations, with ecological sanctuaries that can now point toward environmental sustainability, and the formation of a culture with two historical times - refinement inherited from the barons coffee, paradoxically linked to the rustic countryside and modernity derived of its proximity to major centers. The results presented here are part of exploratory research, but were presented at different events, emphasizing the baroque character of practices derived from these two historical times and tourist potential related to the “cultura tropeira” and to hospitality that marks this countryside.

A presença brasileira na América do Sul: ações e instrumentos de política externa

In this paper, the performance of Brazilian foreign policy in South America during the governments of Lula da Silva (2003-2010) and Rousseff (2011-2014) is discussed. It is showed that this activity has expanded in areas of greater consensus in the internal and external contexts. Thus, although with contradictions, initiatives to implement the infrastructure integration of transport, communications and energy into a political project, expansion of the role of the BNDES in the region and improvement of regional technical cooperation have been increasing.

Direitos de propriedade e usos econômicos da terra:um estudo de caso de assentamentos de reforma agrária no sul do Pará

This article discusses the Brazilian land problem related to property rights of rural land. After emphasizing the importance of land policies in order to define and distribute rural land properties rights, we show how in Brazil the institutions of rural land registering and cadastering as separated processes debilitates the property rights, making them vulnerable to the effective occupying actions. In order to illustrate it, in this article we analyze Data based in a Case Study of conflict and property rights distributions in an important farming and mining region of southern Para state, in Brazil.
