A investigação desenvolve-se em dois níveis um é a revisão bibliográfica geral e específica, como estudo do contexto sócio-político e econômico que dá origem à urbanização por expansão das periferias' e das práticas de mobilização da maioria pobre da população urbana em seus locais de moradia contra o agravamento de suas condições de vida; o outro nível é constituído pelo estudo de caso da Zona Sul de São Paulo nos anos 70, que a partir da coleta de dados e da reconstrução histórica dos movimentos locais no período considerado, pretende obter respostas às questões detectadas no primeiro nível e rebatê-las ao plano técnico.

Este trabalho se destina a montar uma estrutura de relações históricas e teóricas que possibilite uma aproximação ao entendimento dos problemas de São Paulo em relação ao planejamento urbano e ambiente político. Resta assinalar que se irã estudar o caso da cidade de São Paulo, o que restringe a validade das conclusões, mas viabiliza uma pesquisa acadêmica desta natureza, sem que se percam elementos essenciais.

O presente estudo foi realizado na Estação Ecológica do Noroeste Paulista, localizada na região de São José do Rio Preto, Estado de São Paulo, Brasil, visando determinar espécies acarinas plantícolas associadas a fragmentos de mata nativa. Foram determinadas 83 espécies, pertencentes a 48 gêneros de 20 famílias, associadas a mais de 60 espécies vegetais. Trinta e oito espécies acarinas foram identificadas nominalmente. As mais freqüentes foram Tetranychus ludeni (Zacher, 1913) (Tetranychidae) e Iphiseiodes zuluagai (Denmark & Muma, 1972) (Phytoseiidae), coletadas sobre 15 e 14 espécies de plantas, respectivamente. A maior diversidade foi observada em Piper sp. (Piperaceae) (21 espécies acarinas), seguida de Luehea speciosa Willd. (Tiliaceae) (17), Alchornea glandulosa Poepp. & Endl. (Euphorbiaceae) (16), Bauhinia rufa (Bong.) Steud (Caesalpinaceae) (14) e Olyra sp. (Poaceae) (12).

This project has been developed to evaluate the possible relationship between the cesspit (pit latrine) in as far as it degrades the quality of underground water. Its importance is due to the fact that in the rural communities in the State of São Paulo (Brazil) this type of cesspit is very common as a means of sewage disposal and these communities use underground water for their supply of drinking water. Rural properties distributed over the rural area in the municipality of São José do Rio Preto were selected. A preliminary study was then set up to determine the social situation and health of the households as well as qualitative evaluations on the type of water supply and sewage disposal of these communities. Campaigns of water sampling then followed and laboratory analyses of water taken from wells were carried out. Parameters were set up to evaluate the potability according to Brazilian legislation (2004) paying attention to microbiologic (coliforms, Crytosporidium sp., and adenovirus). The analyses showed evidence of possible interaction between the wells and the sewage effluents and drainage in these communities. A PCR reaction to detect adenovirus showed a presence in 53.3% of the samples. The tests for the detection of Cryotosporidium sp all showed a negative result.

Ostriches' erythrocytic parameters help on the diagnosis of specific pathologies and serve as basic knowledge for studies in comparative avian pathology. To obtain reference values of erythrocyte indices for ostriches (Struthio camelus) raised in a commercial system in Brazil and verify if there are differences between gender and age groups, 240 healthy from both sexes animals were bled. Heparinized blood samples were analyzed using standard techniques to determine the red blood cell (RBC) count, hemoglobin concentration, packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) values, besides the red cell morphometry analysis using a computer software that calculates the greater and the smaller diameters of the erythrocytes. Prior to data analysis, ostriches were divided into three different age groups: from four to 13 months, from 13 to 23 months and from 23 to 30 months the. Younger ostriches presented lower erythrocyte indices than the older ones. The age group effect was only significant in females for the erythrocyte, hemoglobin, MCV, MCH, and MCHC variables. The female ostriches presented PCV, MCV, MCH, and MCHC values significantly higher than males in some age groups. It was observed that the erythrocytes of the female ostriches are more elongated and larger than males. It was concluded that erythrocytic parameters of ostriches in São José do Rio Preto-SP, Brazil are influenced by gender and age, highlighting the importance of consider besides these factors also the geoclimatic conditions to an adequate interpretation of the erythrogram.

We examined the course of spermatogenesis and the meiotic chromosome complements in aquatic species of true bugs, Heteroptera. The chromosome complement of the Veliidae species was 2n = 39 (38A + X0) and 23 (22A + X0) in Rhagovelia whitei and Rhagovelia sp, respectively, and in the species of the Notonectidae (Martarega sp) it was 26 (22A + 2m + XY); all collected from the region of São José do Rio Preto, SP, Brazil. An impressive characteristic of the first analysis was the size of the cells belonging to Martarega sp, which were six times larger than the same cells in Pentatomidae and twice as large as the cells in aquatic Heteroptera (Gerridae). Regarding spermatogenesis, all the species analyzed showed the same pattern: holocentric chromosomes and elongated spermatids with the chromatin distributed evenly along the head. The family Veliidae showed several bodies impregnated with silver nitrate at prophase, while the family Notonectidae displayed only one. The cells of Notonectidae also showed an evident and round body until the end of prophase I and in the family Veliidae the silver-impregnated bodies were disorganized, where the only region visualized was possibly that of the NOR. In metaphase, silver-stained regions were found at the periphery of all chromosomes in Veliidae and at the periphery of some chromosomes in Notonectidae. The spermatids of Veliidae showed a less silver-impregnated vesicle, while Notonectidae showed silver staining only in part of the nuclear membrane. Therefore, families of Heteroptera have some differences and features that can help identify and classify these species.

This study aimed to evaluate the helminth parasites of Geophagus proximus from the São José dos Dourados River, a tributary of Paraná River, Ilha Solteira Reservoir, São Paulo State, Brazil. From May 2006 to May 2007, 116 G. proximus specimens were examined and seven different taxa of helminth were collected and identified: proteocephalidean plerocercoids (Cestoda); metacercariae of Austrodiplostomum compactum, Clinostomum heluans and Clinostomum sp. (Trematoda); and Raphidascaris (Sprentascaris) hypostomi, and larvae of Raphidascaris sp. and Contracaecum sp. (Nematoda). All parasites presented the typical aggregated pattern of distribution, as well as the presence of a high number of larval stages, an absence of influence of the host sex and seasonality upon community parameters, as well as a correlation between species richness and host body weight. Moreover, with the exception of A. compactum metacercariae, all helminths found in this study are reported for the first time in G. proximus. Copyright © Cambridge University Press 2012.
