Foram estudadas 247 espécies de aranhas (Araneomorphae, Dionycha) dos estratos arbustivo e arbóreo de seis ecossistemas na região de Botucatu, São Paulo, Brasil, e sua coexistência foi analisada por meio de uma matriz de comunidade. Espécies relativamente abundantes são predominantemente generalistas, independente de seu ambiente; espécies representadas apenas por poucos individuos foram numerosas, e consideradas como membros marginais das comunidades. 0 coeficiente rnédio de interação comunitária foi estimado para cada espécie, assim como a covariação para as espécies mais abundantes em cada ecossistema. Há evidéncia de que a distribuição agregada de plantas favorece as espécies mais especializadas. Abstract Two hundred and forty seven species of dionychan spiders from the shrub and tree layers of six habitats in the region of Botucatu, State of São Paulo, Brazil, were studied, and their strategies for Coexistence were determined through construction of a community matrix. Spiders with relatively greater abundance behaved largely as generalists, independent of their environment, species represented by only a few individuals were numerous, and were considered to be marginal members of the communities. Estimates of the average community interaction coefficient for each species, and of covariation of the more abundant species in each ecosystem, indicate that the spiders avoid competition by spatial partioning, or by adopting differential strategies for habitat use, or because they belong to different guilds. In relation to the aggregate distribution of plants, species tend to specialization, and thus alter their strategy to follow the availability of resources in the environment. These results, together with accumulated knowledge of the ecology of spiders, lead to observations on the subgroup as agent of stabilization in insect populations. Résumé Un programme de prospection des araignées a été realisé dans la region de Botucatu (São Paulo, Brésil). Les strates arbustifs et arboricoles de six écosystèmes on été echantillonnés et 247 espèces d‘áraignées (Araneomorphae, Dionycha) ont été recueillies. Leur coexistence a été analyseé par one matrice de communauté. Les espèces relativament abundantes sont dans la grande majorité des especes généralistes, quelque que soit leur habitat. Beaucoup d’espèces avaient peu d'individus et peuvent être considdrées comme espêces marginales. Le coefficient moyen d'interaction de communauté a été estimé pour chaque espèce, aussi bien que la covariation pour les espéces les plus abondantes dans chaque ecosystéme. Nous avons aperçu que la distribution agrégeé des plantes rend evident la presence des espèces les plus specialiseés.

Small-scale fisheries have a great socioeconomic importance in Brazil. Different regional characteristics along the coast, mostly related to landing sites, equipment used, and targeted species, renders its assessment and monitoring difficult. The aim of this paper is to present a list of species of bony fishes (Teleostei) caught by artisanal fisheries along the São Paulo coast, southeastern Brazil and to provide comments on the relative abundance and conservation status of those species. A total of 315 fishing fleet landings were surveyed, and 106 species distributed among 38 families were recorded. Sciaenidae and Carangidae were the most frequent families in species number. The southern king weakfish, Macrodon atricauda, was the most abundant species, representing 28.03% of the total number of specimens caught. Eleven of the most abundant species are classified as Overexploited in the country or as Near Threatened in the state of São Paulo. These findings reinforce the relevance of assessing and managing artisanal fisheries.

Between april 2005 and May 2006, according to the pressuposts of line transect methodology, census were carried to estimate abundance and population density of Callicebus nigrifrons Spix, 1823 (Pitheciidae) in Cantareira State Park, State of São Paulo, southeastern Brazil (23°23'42"S, 46°35'27"W). After 275.80 Km of census sampling effort, the titis were the second most abundant primate species, presenting an abundance index of 1.4 groups for each 10 km walked and a density estimate of 12.21 ind./km² (ranging between 8.45 a 17.63 ind./km²). The collection of ancillary data during the census allowed the determination of diet and habitat use by the titis groups, and results show a relative adaptability to disturbed habitats.

Terrestrial Isopods were sampled in four protected Atlantic Forest areas located in Serra do Mar, state of São Paulo, southeastern Brazil. A total of 2,217 individuals of six species (Atlantoscia sp., Benthana werneri, Pseudodiploexochus tabularis, Pudeoniscus obscurus, Styloniscus spinosus and Trichorhina sp.) were captured in pitfall traps. The exotic species S. spinosus is recorded for the first time for the Americas. Another introduced species, P. tabularis, previously recorded only from the state of Rio Grande do Sul, had its geographic distribution extended to the state of São Paulo. The most abundant isopods in this study belong to an undescribed species of Atlantoscia.

The clinical and laboratory data of a disease in a resident of Ribeira Valley, São Paulo State, southeastern Brazil, caused by an agent close or identical to Caraparu, a Group C arbovirus, was described. Although there is evidence of an intensive circulation of several arboviruses in the area, no diagnosis of human disease by these agents has been made, except the encephalitis cases caused by Rocio virus during an epidemic in 1975-1977. An antigenic difference between Caraparu strains isolated in São Paulo and in Pará States and a close antigenic relationship between Caraparu strain from São Paulo and Bruconha virus were suggested by the serological tests.

OBJECTIVE: To describe the percentile distribution of body mass index (BMI) in school adolescents, by gender and age, comparing them with international parameters. SUBJECTS AND METHODS: The study included 8,020 adolescents aged 10-15 years from 43 schools in the city of São Paulo, southeastern Brazil. BMI values of the study sample were distributed in percentiles and compared to international parameters (CDC, Must and cols. and Cole and cols.). RESULTS: Both male and female adolescents aged 10 to 14 years showed BMI cut-offs over the international parameters, especially in the P50-P85 percentile range. At the age of 15, the observed values were very similar to reference data; however, BMI values in the 95th percentile were much higher than international parameters. CONCLUSIONS: The study results show how important it is to use adequate BMI values for Brazilian adolescents aged 10-15 since international parameters may not reflect the actual nutritional status of this group.

OBJECTIVE: To analyze the association between dietary patterns and oral cancer. METHODS: The study, part of a Latin American multicenter hospital-based case-control study, was conducted in São Paulo, Southeastern Brazil, between November 1998 and March 2002 and included 366 incident cases of oral cancer and 469 controls, frequency-matched with cases by sex and age. Dietary data were collected using a food frequency questionnaire. The risk associated with the intake of food groups defined a posteriori, through factor analysis (called factors), was assessed. The first factor, labeled "prudent," was characterized by the intake of vegetables, fruit, cheese, and poultry. The second factor, "traditional," consisted of the intake of rice, pasta, pulses, and meat. The third factor, "snacks," was characterized as the intake of bread, butter, salami, cheese, cakes, and desserts. The fourth, "monotonous," was inversely associated with the intake of fruit, vegetables and most other food items. Factor scores for each component retained were calculated for cases and controls. After categorization of factor scores into tertiles according to the distribution of controls, odds ratios and 95% confidence intervals were calculated using unconditional multiple logistic regression. RESULTS: "Traditional" factor showed an inverse association with cancer (OR=0.51; 95% CI: 0.32; 0.81, p-value for trend 0.14), whereas "monotonous" was positively associated with the outcome (OR=1.78; 95% CI: 1.78; 2.85, p-value for trend <0.001). CONCLUSIONS: The study data suggest that the traditional Brazilian diet, consisting of rice and beans plus moderate amounts of meat, may confer protection against oral cancer, independently of any other risk factors such as alcohol intake and smoking.

The herpetofauna of São Paulo State, Brazil, can be characterized as the most well-known in the country. However, despite the large number of studies in this area, there are still many sampling gaps within biomes such as the Atlantic Forest that are considered global conservation priorities due to the high rate of endemism and human disturbance. As a result of political and historical pressure, this biome has been reduced to less than 12% of its original extent and, despite its importance for global biodiversity conservation, only a small percentage of its original vegetation cover (1%) has some form of legal protection. This is the case of the Parque Estadual Turístico do Alto Ribeira (PETAR) which, together with the Parque Estadual de Intervales, Parque Estadual Carlos Botelho and Mosaico de Unidades de Conservação de Jacupiranga, forms of an ombrophilous forest continuum of 360 thousand ha in the south of São Paulo State. This study presents a list of amphibians and reptiles from the PETAR, with information on the local distribution and habitat use of the species. The survey was conducted from October to December 2009, completing a total of 15 sampling days using four complementary methods of active sampling: visual encounters, auditory encounters, searches by car and incidental encounters. We recorded a total of 91 species belonging to 53 genera and 24 families. This high diversity can be attributed to the existence of a wide variety of habitats and microhabitats in this region, such as the various aquatic sites used by many species of anuran amphibians. Moreover, the PETAR features a large altitudinal gradient (80 - 1,160 m elevation) that gives a large climatic, geological and hydrological heterogeneity to the area. This inventory is an important contribution to the expansion of knowledge about these assemblages in the Atlantic Forest to the south of Serra de Paranapiacaba mountain range, and provides support for the conservation of these groups in São Paulo State.
