Estudo de comunidades de foraminíferos em manguezal do Rio Itapanhaú, Bertioga-SP, aplicado à reconstrução paleoambiental

Foraminifera scientific studies became, historically, of your apply in relative dating of rocks, stratigraphic correlations and paleoenvironmental reconstruction. In the last decades, they have been applied on the studies of modern ecosystems, with or without antrhopic influence. Both aspects are interest of petroleum industry. Among other approaches, foraminífera are used as good indicators of the fluctuation of relative sea level. This study aimed to survey and taxonomic study of the community structure of foraminifera in surface samples of a core, 60 cm, collected in mangrove located in Itapanhaú river in Bertioga (SP).It also aims to contribute to the discussion about typical patterns of community structure of mangrove margins and provide elements for discussion on the relative sea level behavior in this area in almost modern times. It was been collected 6 samples along the core of 60 cm of length, each one 10 cm depth. They were made in laboratory and in each sample sought to find at least 100 foraminifera per ml. The species identification was made with reference specified material and collection available on IGCE-UNESPetro, Rio Claro. The community structure was studied in terms of richness, diversity and species composition and was made the results comparison from similar areas to interpret the depositional environment. Were found 21 species within them 13 calcareous and 8 binders, being the most abundant and frequent species Ammonia tepida, Ammonia parkinsoniana e Elphidium spp. Essentially there wasn’t change in the community structure within the period covered by the core which reflects an environment of outer margin of mangrove without noticeable change in relative sea level at the respective time of deposition of muddy sediments. The community structure here recognized its similar to estuarine environment well maintained which indicates a low human impact in the area over the time interval. The agreement of the results...

Sincronia das bolsas de valores

This study aims to analyze various index stock exchanges around the world, with mathematical methods, analyzing the Product Distribution function (PDF), cumulative distribution and correlation. It is thought that the world economy is connected, as if the financial markets were a network, where the fluctuation of a market generates a variation on another and another, creating a pattern, that this change will affect the entire network, thus creating what we might call the domino effect. From this we intend to study, using as a basis the main index of the major stock exchanges around the world the relationship they have with each other, analyzing the influence and correlation that generates this effect, showing that markets are connected and influence each other. We can see this effect in the crisis of 2008, where the U.S. market from one moment to the other was shaken, affecting the whole world in a few days, creating effects that are felt in the present day

A influência do ciclo estral no comportamento das linhagens de ratos congênica SLA16 e isogênica SHR

Several studies use only male rats in their experiments, even with all the evidence of differences between the sexes, not only in the reproductive behavior but also in the development of diseases. This absence of studies using female rats is due in part to the estrous cycle. It is known that one estrous cycle lasts four to 5 days and consists of four phases: proestrus, estrus, metestrus and diestrus. Ramos et al. (1999) identified and mapped a QTL in an F2 population derived from interbreeding of strains of SHR (spontaneously hypertensive rats) and Lewis (LEW) rats and found, on chromosome 4, the first QTL of the world related to anxiety in rats. After several backcrosses between SHR and LEW strains, it was developed a congenic strain called SLA16, to refine the study of this QTL. This QTL corresponds to a large genomic region, approximately 75 million basepairs (Mb), and was first called Ofil1 (inner open field locomotion 1). Currently it is called Anxrr16 (anxiety-related response region 16) according to the rat genome database (RGD). Izidio et al. (2011) suggested that the natural fluctuation of the hormones in the estrous cycle of female rats could influence the effects of this locus on behavior. That is, females in DP (diestrus-proestrus) present the QTL in the same genomic region that males, while females in EM (estrus-metestrus) do not present it. The effects of the estrous cycle in the SLA16 strain and its isogenic control SHR were analyzed on the elevated plus maze (EPM), black and white box and on the open field test (OF). In the open field test, the SLA16 strain had higher central locomotion (F=5.0, p <0.05) and peripheral locomotion (F=12.6, p <0.01) compared to the SHR strain. In the elevated plus maze test, the SLA16 strain had the higher number of entries (F=9.5, p <0.01) and time spent in the open arms (F=10.3, p <0.01) compared to the SHR strain. Finally, in the black and white box test, the SLA16 lineage spent more time ...

A sazonalidade ambiental afeta a composição faunística de Ephemeroptera e Trichoptera em um riacho de Cerrado do Sudeste do Brasil?

In this paper, data on the fauna of Ephemeroptera and Trichoptera (ET) from a Cerrado stream was analysed in order to test the hypothesis that the high seasonality of this biome can influence the composition of ET between the wet and dry seasons. The community structure was evaluated using Detrended Correspondence Analysis and Cluster Analysis (Morisita Horn-UPGMA). Environmental factors were analyzed using the Principal Components Analysis. In order to test the effect of abiotic variables on the fauna, It was applied the Procrustean Randomization Test (Protest) and Mantel Test. The environmental factors recorded for this study had a significant effect on the ET fauna from Córrego do Pedregulho. Faunal similarity was high throughout the year, indicating that although there was density of fluctuation, due to rainfall variation, the faunal composition showed little temporal variability. On the other hand, it was possible to observe that the genus Lachlania (Ephemeroptera) occurred preferably during the rainy months and that the faunal composition during the dry season was less variable than those from other seasons. Therefore, environmental seasonality had a partial effect on the faunal composition of ET from Córrego do Pedregulho.
