Regeneração natural em ecounidades maduras e em reorganização de fragmentos de Floresta Estacional Semidecídua

The Atlantic Rainforest biome has been going through fragmentation processes caused by agriculture and urbanization in green areas. Structural studies associated with the silvigenetic approach allow the understanding of what the past has caused in the present structure and predict future conditions of disturbed fragments. The objective of this study was to compare the composition and diversity of arboreous natural regeneration of steady-state and reorganization ecounits in two Seasonal Semideciduous Forest fragments. The hypothesis was that specific composition varies in these two different ecounits due to differential adaptation of species in canopy gaps and closed canopy. The survey was made in three areas with different perturbation backgrounds of 0,5 ha each. 60 permanent plots of 4m² each (2m x 2m) were stablished along the studied fragments following the proportion of ecounits presented in a previous mapping. Each plot was divided in 4 sub-plots of 1m² and arboreous individuals between 0,20m and 1,30m height were sampled and posteriorly separated in two height classes: I) individuals between 0,20m and 0,50m height (2m² sampling) and II) individuals between 0,51m and 1,30m height (4m² sampling). It was sampled 338 individuals from 53 families and 23 species. The Shannon index was 3,26 (Area A), 2,27 (Area B) and 2,42 (Area C) whereas Areas B and C values are considered low in our state Semidecidous Forests. Steady-state ecounits presented the highest values for abundance and species richness. Chi-square test pointed out species’ selection for determined ecounits in the studied community. Rarefaction method analysis showed diversity increase in steady-state ecounits and a stablishment in species richness curves for reorganization ecounits

Diversidade de Formicidae (Hymenoptera) em um fragmento de Floresta Estacional Semidecídua no Noroeste do Estado de São Paulo, Brasil.

(Ant diversity (Hymenoptera) in a fragment of Semidecidual Seasonal Forest in Northwest of São Paulo State, Brazil). Due to scarce knowledge about ant fauna from Northwestern São Paulo State, the present study aimed to know the taxonomic diversity of Formicidae, relating the results to climatic variation along of one year. The samples were gotten monthly, using pitfall traps. It was sampled 25 species of 15 genera and seven subfamilies. Myrmicinae was the sampled richest subfamily, follows by Formicinae and Ponerinae. According Wilcoxon test, the species richness, equability and diversity estimated by Simpson index were significantly higher in the rain season. The obtained results suggest that the abundance of ants is significantly related to the temperature variation, while the ant assemblage structure is related to thermal and pluviometric variations.

Campesinato e agrohidronegócio canavieiro no Pontal do Paranapanema: os desafios para a transição agroecológica

This paper appears in order to promote a discussion on the use and ways of working with the land. For this, we present a scenario of conflict initiated in Pontal do Parananema, São Paulo, Brazil, between the peasantry and the agrohidronegócio. The Pontal is a territory marked by agrarian and land conflicts, originated by the illegal occupation of land by the squatters, the decimation / expropriation of indigenous, and deforestation and environmental devastation. This conflict is represented today by the sugarcane agro-industrial capital companies on one side, and the other peasants. The expansion occurs agrohidronegócio strongly from 2005, due mainly to the change in the energy matrix of the country and state incentives with strong momentum in the production of flex-fuel vehicles. Rural agrarian reform settlements, made possible by the state under pressure from social movements, are spatialized in 16 municipalities with a total of 112 settlements, occupying an area of 139. 682 hectares, seating 5. 892 families. These families have seen their possibilities of social reproduction increasingly suppressed by the advance of sugarcane agrohidronegócio in the region, which suffocates the living spaces and work of these peasants. Front of it, agroecology is an alternative for these workers to ensure their reproductive possibilities. Agroecology also arises as a means of confronting agribusiness model, adding elements to the environment, such as the eradication of the use of pesticides and considering the dynamics of nature to promote agriculture, and social order, contributing food sovereignty and the production of healthy food and diversity to the population...

Gênero e diversidade na escola: reflexões acerca da formação continuada sobre assuntos da diversidade sexual

This article aims to discuss reports brought by the teacher the early years of public school in the training course in Gender and Diversity in School (GDS), with regard to the prejudices of gender and sexual diversity. The GDS training course was offered in 2009 and 2010, by the Open University of Brazil (UAB), in cooperation agreement with the Universidade Estadual Paulista (Unesp). In São Paulo the training centers were distributed in 09 municipalities. The course GDS was inserted in the modality teacher continuing education elementary education from the public schools, in the semipresencial way, and it was divided into five thematic modules: diversity, gender, sexuality and sexual orientation, race / ethnicity. In this article, we present the analysis of the memorials written by / the teacher / participants of the 1st GDE course, polo Jau, in the state of São Paulo, that link the learning which was experienced in the course. Were obtained reports about conflicts arising from the dissonance of personal beliefs and professional responsibilities; involvement of the life’s history of the teacher in his performance in the school (subjectivities); transposition of conceptual errors built out of school, between other aspects. It could be observed that the course has destabilized these teachers with some questions about their certainties. The difficulty in changing and transforming concepts and prejudices about sexual and gender diversity was clarified during the course. The course enabled the educators the contact with contemporary questions, reflect on their attitudes and conceptions of education, which can help to transform their practices in school, providing new perspectives on the issue of sexuality
