The perception of modern society regarding the nature and indigenous peoples came to be shaped in the sixteenth and seventeenth centuries, with two major events, the invasion of Europeans in America and the scientific revolution. These events symbolize the cultural overlap and European thinking about the rest of the world. The current scenario is industrialism, consumism and cultural standardization driven by Cartesian thought. This work demonstrates, through literature research and data analysis, that this dominant model has caused the crisis of modernity, focusing especially on the environmental crisis that threatens human life. The solutions are present in the modern society the knowledge of indigenous peoples that is inherently ecological and sustainable by tradition. From the union of diverse cultures and knowledge dialog you can find solutions for today's problems and provide a renewal of relationships between modern society, indigenous peoples and nature. The World Conscious Pact presents this proposal which can be increased through public relations strategies in order to reconnect the man-nature bond, generating critical behavior with respect to the current dominant system and motivate society to adopt truly ecological postures. For this it is necessary to rescue the Earth image as a mother

The aim of this study was to analyse the genetic diversity and agronomic performance of a group of advanced and superior strains of soybean, derived from biparental, four-way and eight-way crosses, in order to identify future promising and superior combinations. The experiment was carried out in the experimental area of the Paulista State University, Julio de Mesquita Filho, Jaboticabal Campus, in the state of Sao Paulo, Brazil. The characteristics under evaluation were: number of days to flowering, plant height at flowering, number of days to maturity, plant height at maturity, height of the first pod, number of branches, number of pods per plant, agronomic value, lodging, one hundred seed weight and seed yield., The Mahalanobis distance and the relative contribution of each characteristic were used to calculate the phenotypic distances. Among the genotypes analysed, 19 strains displayed high productivity, being superior to the controls (V-max, CD 216, CD 219 and Conquista). The greatest distance found was between strains JAB 41 and JAB 17 (279.81), followed by JAB 40 and JAB 17 (261.38) and between JAB 40 and JAB 22 (255.46). There were six groups formed using the Ward method, indicating the presence of genetic variability among the tested strains. Increasing the number of parents had no effect on the increase in genetic diversity between the strains, and was not the factor responsible for the grouping or not of the genotypes under test.

Brazilian southeastern region has soil and climate conditions suitable for the growing of rubber trees, and most part of national yield arises from São Paulo State. The aims proposed for this work were to determine the diversity, the richness and the seasonal occurrence of mites found in a rubber tree crop in a triennial survey with monthly samplings, as well as to estimate the populational density of the major phytophagous species. This study found 74,407 mites from 26 species belonging to 10 families. The phytophagous and predators represented 95.4% and 3.9% of the total abundance, respectively. Twelve species were rare, six accessories and eight constant. The families Phytoseiidae and Tydeidae had the greatest richness (five and four species, respectively). The most numerous species was Calacarus heveae Feres (50,573), with great abundance at the end of rainy season until the beginning of dry season. Among predators, the most abundant were Zetzellia quasagistemas Hernandes & Feres (1,345), Pronematus sp. (455), Zetzellia agistzellia Hernandes & Feres (409) and Euseius citrifolius Denmark & Muma (243). C. heveae had greatest densities on March and April 2003, and Lorryia formosa Cooreman and Tenuipalpus heveae Baker on March and May 2001, respectively. Many stigmaeids were observed in association with colonies of L. formosa preying their eggs and immatures.

Este estudo foi desenvolvido no riacho Taquaral, que integra a Bacia hidrográfica do Pirapitingui, localizado na cidade de Itu, estado de São Paulo. A pesquisa foi conduzida com a finalidade de comparar a diversidade da ictiofauna em três pontos distintos de um trecho do riacho, além de obter variáveis ambientais físicas e químicas que poderiam distinguir as características abióticas e influenciar as particularidades bióticas de cada ponto. As coletas foram realizadas com materiais de pesca que consistiram em redes de espera, peneira e armadilhas de fundo do tipo covo. Uma lista das espécies foi elaborada utilizando-se de cálculo de riqueza, abundância relativa e abundância total por ambiente amostrado para então realizar as análises de diversidade se utilizando do Índice de Shannon por local de coleta, o qual assume que os indivíduos são amostrados ao acaso com origem em uma população indefinidamente grande e que todas as espécies são representadas na amostra. Além desse índice foram considerados os índices de similaridade de Jaccard, que compara a similaridade das espécies de dois locais levando em conta a presença ou ausência das espécies e o Índice de Morisita -Horn que abrange também a abundância dessas espécies. No total foram capturados 3490 exemplares pertencentes a 5 ordens e 7 famílias, em um total de 15 espécies, sendo que em um dos pontos (ponto1) foi observado menor quantidade de espécies e menor número de exemplares (8 espécies e 49 exemplares). Os demais pontos (pontos 2 e 3) obtiveram igual número de espécies (13), além dos maiores números em exemplares ( 1447 e 1994, respectivamente). Os resultados apontam a existência de diferenças nas características ambientais, também resultantes de influências antrópicas na região e consequente diferenciação na diversidade dos três pontos amostrados. A diversidade observada no Ponto 1, a partir do Índice de Shannon, foi a maior em...

This work has as its theme the multiculturalism, cultural diversity and their reflections in school everyday, more specifically on the interactions between the various subjects and social groups that make up a school and the teacher as mediator of the relationship between these guys. The theme Multiculturalism refers in the first instance, to the theoretical movement beginning in the mid-20th century in the United States and that spreads in the Western world as a way of tackling the conflicts generated depending on the economic issues, policies, and, in particular, cultural-ethnic, in an attempt to combat discrimination and prejudice, given the difficulties of individuals and groups to welcome and socialize with the plurality and cultural differences (SILVA; BRANDIM, 2008).At the same time, multiculturalism refers to cultural studies, through the Centre for Contemporary cultural studies, founded by em1964 Hoggart, and connected to the English language Department of the University of Birmingham in England.In contemporary times, due to the phenomenon of globalization and public policy to challenge prejudice and discrimination the subjects and social groups, regardless of color, creed, ethnicity, sexual orientation and nationality, this theme has been recurring in order to recognize plural identities and ensure and directly affects the school as a place of cultural diversity and conflicts generated by the very diversity.The present work aims to analyze and understand how the issue of multiculturalism and cultural diversity in school films. Our study will be based theoretically in Cultural Studies authors and uses the qualitative approach, working with movie content analysis of school, seeking to seize on the same relations of coexistence, conflicts and the mediations of teachers

A Região Sudeste do Brasil apresenta aspectos edafo-climáticos favoráveis para o plantio e desenvolvimento da seringueira, sendo o estado de São Paulo o maior produtor nacional de látex. Este trabalho teve como objetivos determinar, através de coletas mensais durante três anos de estudo, a diversidade, a riqueza de espécies e a sua sazonalidade, bem como realizar estimativas de densidade populacional das principais espécies de ácaros presentes nas folhas. Todos os ácaros foram montados em lâminas de microscopia, totalizando 74.407 indivíduos, de 26 espécies pertencentes a 10 famílias. Os fitófagos representaram 95,4% do total de indivíduos coletados e os predadores 3,9%. Doze espécies foram consideradas acidentais, seis foram acessórias e oito constantes. Apresentaram maior número de espécies as famílias Phytoseiidae (cinco) e Tydeidae (quatro). A espécie mais abundante foi Calacarus heveae Feres (50.573), com maior abundância nos meses correspondentes ao término da estação chuvosa e início da estação seca na região. Dentre os predadores, a mais abundante foi Zetzellia quasagistemas Hernandes & Feres (1.345), seguida por Pronematus sp. (455), Zetzellia agistzellia Hernandes & Feres (409) e Euseius citrifolius Denmark & Muma (243). C. heveae apresentou maior densidade populacional em março e abril de 2003, e Lorryia formosa Cooreman e Tenuipalpus heveae Baker em março e maio de 2001, respectivamente. Muitos estigmeídeos foram observados associados a agrupamentos de L. formosa predando seus ovos e estágios imaturos.
