A prática da Restauração Ecológica teve um aumento considerável nas ultimas décadas no Brasil, a fim de remanejar a integridade ecológica dos ecossistemas degradados. No entanto, em virtude da prática ser ainda recente faz-se necessário maiores estudos na área para compreender a relação e a importância dos frugívoros nas redes de interações, bem como as mudanças no desenvolvimento da biodiversidade durante o processo de restauração, visando otimizar os resultados de práticas futuras. Desse modo, o presente trabalho teve como finalidade analisar a estrutura da comunidade de aves do sub-bosque, bem como determinar as principais espécies envolvidas no processo de dispersão de sementes realizado por elas em três áreas restauradas do interior de São Paulo (Iracemápolis, Santa Bárbara d’Oeste e Cosmópolis), com diferentes idades de plantio (14, 25, 57 anos respectivamente), tendo uma área nativa como referência. Para isso foram realizadas redes de neblina para capturar as aves do sub-bosque, e coletar amostras de fezes, afim de se analisar possíveis sementes no conteúdo estomacal/intestinal. Constatou-se que a espécie de Turdus leucomelas foi a mais abundante em todas áreas de estudo, e a mais expressiva para a dispersão de sementes. Iracemápolis e Santa Bárbada d’Oeste apresentaram a maior taxa de captura de indivíduos, enquanto que Cosmópolis apresentou a maior similaridade da avifauna com a mata nativa. Em relação à distribuição das guildas alimentares da avifauna nas áreas, predominaram-se espécies insetívoras em detrimento da baixa presença de frugívoros. Em conclusão, há uma importância significativa da restauração em áreas degradadas para recrutar a avifauna, mesmo que a maioria dos indivíduos sejam de espécies menos sensíveis à fragmentação

A agricultura em ambientes urbanos (AU) é um fenômeno socioambiental crescente em todo o mundo e pode estar associada à promoção de segurança alimentar e nutricional de uma população. No Brasil, o movimento da revolução verde favoreceu a monocultura e a concentração da posse da terra, que, decorrentemente impulsionaram o êxodo rural, em que os pequenos agricultores, na busca por melhores condições de vida, se locomoveram aos centros urbanos. O município de Santa Gertrudes, localizado no interior do estado de São Paulo, apresenta 98% dos habitantes residindo na zona urbana. O objetivo deste trabalho é compreender a agricultura urbana do Município de Santa Gertrudes, abordando: o perfil dos agricultores, as suas motivações, os seus locais de plantio e suas escolhas de cultivos, enfocando principalmente em lotes vagos na malha urbana. O estudo foi realizado em três etapas a partir de uma abordagem etnobotânica: 1) mapeamento dos lotes cultivados, 2) censo que abordou as questões socioeconômicas e de cultivo e 3) estudo detalhado com uma amostra determinada aleatoriamente, que aborda as condições socioeconômicas dos agricultores, suas histórias de vida, a caracterização do ambiente de plantio e o levantamento das espécies cultivadas, a partir de um inventário, com ênfase em raízes e tubérculos. Para o levantamento dos mesmos utilizou-se de entrevistas estruturadas e semi-estruturadas. As análises dos dados foram realizadas de maneira descritiva. Foram encontrados 52 lotes cultivados, destes, 43 participaram do censo e 20 da amostra. Os agricultores são representados principalmente por homens, a maioria é idosa e migrante de zonas rurais e grande parcela destes é oriunda do estado de Minas Gerais. Mais da metade dos lotes cultivados estão em áreas institucionais. As atividades realizadas são voluntárias e motivadas em grande parte por interesses individuais, trazendo benefícios para os praticantes em...

The cultivation of grapes is one of the most traditional cultures and the world's oldest one. In Brazil, cultivars occupy an area of approximately 90 thousand hectares, covering the south, southeast and northeast, in latitudes ranging from 30 º 56 '15''S up to 5 º 11' 15''S. The culture of the vine may be the target of the attack of some diseases and pests, and currently the main concern for growers is the subterranean mealybug, Eurhizococcus brasiliensis (Hemiptera: Margarodidae), known as pearl-ground. This arthropod infests the roots causing a progressive languish of the vine, even causes its death. In southern Brazil it is known that some species of ants can disperse pearl-ground for short distances, however, there is no information about that in the State of Sao Paulo. Thus, it is extremely important to perform studies with this focus on wine regions in this State. Therefore, this study aimed to identify the species of underground ant community in different grape varieties found in vineyards in the town of São Roque – SP, Brazil. With that purpose, samples were collected within one year. We used underground pitfalls spread across twelve points. In each of the points were placed two traps, one containing honey and the other containing sardine as attractive. The results revealed the presence of three morphospecies of ants in Niágara Rosada and four in other grape varieties, there was no significant difference in the species richness among the cultivars (Kruskal-Wallis - 0.33, p = 0.5). In both trials, the most frequent species was Brachymyrmex sp.4, suggesting that there is no dominance of distinct species of Niágara Rosada and the other grape varieties. There was no dissimilarity in species richness of the ones visiting honey or sardines (Kruskal-Wallis - 0.08, p = 0.7) and the analysis of variance indicated a great similarity in species richness between the rainy and dry seasons (Kruskal-Wallis - 0.09, p = 0.7)

The Atlantic forest has a large number of endemic species due to the varieties of environments, altitudes, and climates found along its distribution. The species Brachycephalus ephippium is an example of endemic anuran from this forest formation, occurring in the states of São Paulo, Rio de Janeiro and Minas Gerais, between 750 and 1200 m altitude. This species is abundant in the Serra do Japi, an Atlantic Forest remnant, which houses high biodiversity, located in Jundiaí city, between three big urban centers in the state of São Paulo. This remnant, which has altitude ranging between 700 and 1300 meters, is threatened by global climate changes and, spite of legally protected, by intense pressure of urbanization. The aim of the present study was to verify the association between of environmental variables with the abundance and distribution of B. ephippium in the Serra do Japi. The air relative humidity showed a positive correlation with the presence of B. ephippium individuals and the best model to explain the abundance involved air relative temperature and litter temperature. These results allowed the investigation of the environment use by this species and can be used to provide conservationist actions

The present work discuss the reproduction of the social relations from the point of view of the new urban production relations - having as empirical universe for analysis-, the Itaquera district in the Sao Paulo metropolis, with the advent of the World Cup in Brazil. Starting with the reading of a reality in movement, in which the analysis walks covering the dialectic relationship between space and society, where the first is translated into product and life reproduction condition, aiming to unveil the metamorphoses that will take place in the urban space with its consequent contradiction, what it may be the expanded capital reproduction concomitantly with the process that denounces a spoliation movement of the social space. With the society approval before these big architectural projects enabled by ideology, it’s determined the (re) production of artificial spaces of consumption, funded for the capital extension. The current stage that the capitalism reveals a space turned into mass consumption merchandise, consequence of the victory of the exchange value over the usage value, amalgamated in positive measures of expulsion/sweeping of low income socio-economic layers

The studies related to research on new antimicrobial products have received special attention from researchers, especially given the emergence of microbial strains resistant to conventional antimicrobials. Thus, the present study was aimed to test the antimicrobial action of hydro-alcoholic extracts of plants collected in Cerrado region of Botucatu, following the species: Achyrocline satureioides (Lam) DC (macela), Stryphnodendron adstringens (Mart) Coville (barbatimão), Miconia rubiginosa (Bonpl.) DC (quaresma-branca), Davilla elliptica A. St-Hil (lixinha), Siparuna guianensis (negramina) e Solanum lycocarpum A.St-Hil (lobeira). The plants were always collected in the morning, in areas near the town of Botucatu, and extracts were prepared using a solvent such as methanol 70% from materials dried (50°C) and ground into mill knives. The extraction was performed for 48 hours at refrigerator temperature, followed by filtration, removal of methanol solvent in a rotary evaporator, determination of the dry weight of the extracts (mg / mL) and phytochemical analysis of the same. The sensitivity tests for 10 S. aureus, 11 E. coli and 11 P. aeruginosa, isolated from human clinical cases were performed by diluting volumes of the extracts in Mueller Hinton Agar (MHA) and determination of minimum inhibitory concentration (MIC) (mg / mL). According to the results and statistical analysis, it was found that depending on the bacteria tested, and in descending order of antibacterial activity for S. aureus: Lixinha sheet > Barbatimão sheet > Quaresma-Branca > Macela > Lixinha fruit > Barbatimão shell > Lobeira > Negramina; E. coli: Lixinha sheet > Barbatimão sheet > Lixinha fruit = barbatimão peel > Quaresma-Branca > Macela = Lobeira > Negramina and P. aeruginosa: Lixinha leaf > Barbatimão bark > Barbatimão leaf > Lixinha fruit > Macela > Lobeira > Quaresma - Branca = Negramina...

The city of São Paulo has, since the beginning of the expansion of its urban sprawl, represented relations of conflicts and contradictions between society and nature. Once the way society relates to nature is defined by how the social agents themselves correlate in certain social and historical contexts, the ways of interaction between the social and natural elements will be different according to the forms of production and appropriation of the urban space. Even more evident is the case of the great national metropolis, given its demographic dimensions and historical conditions, the process of urban expansion follows a logic where spaces of better quality for housing are occupied by those of better financial conditions. Thus, although there are exceptions, the poorest people live in places less desirable, in less resilient environments of lower environmental quality, relating to nature and its phenomena with greater risks. These risks are reflected here as recurring flooding, mudslides and landslides for which the rain is constantly blamed. So we have a situation where it is clear that a weather phenomenon differently interacts with different social groups. In this context, the study was conducted to compare extreme events occurred in two regions of São Paulo: the Freguesia do O, in the north side, and M'Boi Mirim, in the south side. Both are regions with large number of risk areas and are in the same urban climate unit. However, they present different conditions of social vulnerability. With the investigation of each extreme rain event occurred in the two regions, in the period of 2000-2010, supplemented by field research, we tried to observe how far the rain, with his intensity and volume, can, in fact, be related to the accidents.

A rápida expansão do espaço urbano no Brasil ocorreu e continua ocorrendo, geralmente, de forma desordenada e sem perspectivas imediatas de ordenação das práticas de uso e ocupação do solo. O planejamento da ocupação do espaço urbano, baseado na racionalidade capitalista, embora englobe fundamentos interdisciplinares, na prática tem sido realizado dentro de um âmbito mais restrito do conhecimento, desconsiderando aspectos fundamentais dessa dinâmica. Essa situação tem resultado em grandes transtorno e custos para a sociedade e para o meio ambiente, atingindo diretamente os sistemas de drenagens urbanos e resultando no crescimento dos eventos de cheia. Assim, o planejamento urbano vem buscando alternativas que possibilitem o alcance do desenvolvimento urbano sustentável. Neste sentido, este trabalho objetiva avaliar qualitativamente a implantação reservatórios de detenção implantados no alto curso da sub-bacia do Alto Tietê, de modo a avaliar os problemas apresentados através da realização de um inventário dos avanços atingidos na incorporação destas medidas no gerenciamento dos sistemas de drenagem nesta subbacia.
