Composição florística e fitossociológica de três fragmentos de floresta ribeirinha em Ajapi, Rio Claro - SP

A vegetação ribeirinha é conhecida como o conjunto de formações que se encontram associadas aos corpos d’água, ocorrendo ao longo dos cursos d’água e no entorno de nascentes, formando um mosaico vegetacional. É de vital importância na proteção de mananciais, controlando a chegada de nutrientes, sedimentos e a erosão de ribanceiras, atua na estabilidade térmica e abastece o lençol freático a partir da contenção de águas pluviais, além de exercer um papel fundamental como corredores ecológicos de fluxo gênico animal e vegetal. No Brasil, há legislação que protege tais áreas, entretanto, estas vem sofrendo sistemática degradação por desmatamento, despejo de esgotos domésticos e industriais, canalização e desvio de cursos d’água. O estudo presente teve como objetivo caracterizar a florística e a estrutura fitossociológica de três fragmentos do ambiente ribeirinho localizados na Fazenda Água Branca, em Ajapi, Rio Claro - SP. Através de parcelas de 10x10m, foram amostrados todos os indivíduos com PAP ≥ 10cm. Foram estabelecidas 16 parcelas na vegetação ribeirinha com influência fluvial sazonal ao longo do Ribeirão Claro, tratadas no trabalho como floresta ciliar. Foram estabelecidas 14 parcelas distribuídas em dois fragmentos de vegetação ribeirinha com influência fluvial permanente, tratadas ao longo do trabalho como floresta paludosa. Na mata ciliar, foram amostrados 316 indivíduos, pertencentes a 32 famílias, distribuídos em 74 espécies. As espécies mais importantes foram: Syzygium cuminii, Esenbeckia febrifuga e Croton urucurana. As famílias com maior riqueza foram: Myrtaceae, Fabaceae, Euphorbiaceae e Meliaceae. O índice de diversidade (H’) encontrado foi 3,62; valor esperado para Florestas Estacionais Semideciduais. Na mata paludosa, foram amostrados 469 indivíduos, pertencentes a 34 famílias, distribuídos em 60 espécies... (Resumo completo, clicar acesso eletrônico abaixo)

Microalgas na Produção de Biodiesel: Extração e Composição Lipídica

The uninterrupted rise in emission of greenhouse gases open way to the use of biofuels, due to politics that focus on fuel safe, clean and renewable. The use of microalgae for biodiesel production has been described as one of the most promising sources of biomass for biofuels. The aim of this study was to evaluate the extraction and lipid profile of the microalgae Dunaliella tertiolecta, Isochrysis galbana and Tetraselsim gracilis. The extractions were performed with solvents chloroform /methanol and petroleum ether. The lipid profile was analyzed by gas chromatography after transesterification.The petroleum ether showed more efficiency in the extraction, the best result obtained was in the microalgae D. tertiolecta with 19.52% of lipid. The lipid profile analysis indicated a biodiesel stable to oxidation and elevated viscosity

Consciência literária e posicionamento político no processo de composição de The Voyage Out, de Virginia Woolf

In this article, a discussion about the implications and developments in the relation between Literature and Politics is proposed in order to demystify generalized critical opinions in literary studies. To do this, articulations between theory and practice are made, based on Virginia Woolf’s composition process of her first novel, pointing out the author’s artistic ability and political consciousness.

Distribuição espacial das assembleias de peixes em dois trechos do alto rio Paranapanema e lagoas marginais associadas: composição e estrutura

Ichthyofaunistic studies aims to broad the knowledge of composition, abundance and distribution of species in certain areas, and when possible, to infer patterns of distribution, as well as extrinsic factors that affect these patterns in space and time. The Paranapanema River suffers the impact of the construction of hydroelectric power plants in cascade system along its main channel, changing the characteristics of lotic to lentic and semi-lentic. These changes affect the entire biocenosis and the surroundings of the reservoir and, in particular, the fish fauna. In this context, the aim of this study was to characterize the fish assemblage in two lakes and stretches of the main channel, located near the outfall of the Paranapanema River, Jurumirim reservoir area, comparing them to their composition and structure, using ecological indices as tools. Fish were caught every three months from April 2011 to January 2013, using gill nets of various mesh openings in four stretches: Environment 1 - Calha Sete Ilhas, Environment 2 - Calha Poço da Pedra, Environment 3 - Lagoa Sete Ilhas and Environment 4 - Lagoa Poço de Pedra. After the capture, the specimens were identified and biometric analysis was performed (total and standard length weight). We captured 4,006 individuals belonging to four orders and 34 species, 31 native species and three non-native species. In abundance (n) and number of species (S), there was a predominance of Characiformes (57 %) followed by Siluriformes (31%). Overall, most of the species was constant concerning the frequency of capture. The five most representative species in abundance were Schizodon intermedius, Cyphocarax modestus, Pimelodus maculatus, Hoplosternum littorale and Serrasalmus maculatus, contributing with 60% of total individuals captured. Regarding the stretches, these species present diversity (H'), evenness (E), dominance (D) and richness (d) of similar species, since the abundance was higher in ...

Relações entre força muscular e composição corporal e regional em idosos

Exercise, in general have the ability to promote health, reduce loss of physical fitness, reduce declines in body composition and prevent disease, and promote improvements in athletic performance, and that's consensual today. Through analysis of body composition and physical fitness, you can diagnose the possible individuals at risk of developing diseases, and fractures caused by falls in the elderly. The DXA tests were used (densitometry by dual beam X-ray) to assess body composition and regional, 1 RM test to evaluate the maximum strength and girth measurements, diameters and skin folds in order to analyze the balance of power muscle with both body composition as regional. The results showed that the variance in bone mass between older content related to the change in the maximum muscular strength of the upper and lower limbs, but the force values are not related to increased muscle mass. The development of muscle strength fulfills a dual function in aging which is to maintain or reduce the rate of loss of lean body mass, and also so the body bone health

Fronteiras nas Américas: tamanho e composição dos domicílios rurais no oeste do Brasil e EUA na primeira metade do século XIX

The study of the size and composition of the rural household in tradicional societies in transition to modern ones is very useful as a tool in order to understand forms and organizations of the domestic groups and their possibilities of survival, social mobility e developing strategies of material accumulation. The aim of this article is to compare the size and composition of the rural households in the frontier regions of the Americas: the northwest and southwest of U.S.A with the southwest of São Paulo province in Brazil. The findings are surprising in comparative perspective, as the mean size of the American households were very high in relation to the brazilian ones. The sources used in this research are the manuscript census of the U.S.A and Brazil.

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.
