Local assemblages of fishes associated with reefs are influenced by interactions among the availability of larvae and survival of recruits with subsequent biotic and abiotic forcing, as well as by periodic and episodic disturbances of varying natures and magnitudes. Therefore, besides being structurally heterogeneous and patchily distributed, reef systems are strongly context-dependent due to the influence of a broad array of ecological processes. In order to assess interactions of local factors that influence the distribution and abundance of reef fishes within a coastal mosaic of rocky reefs, we tested the null hypothesis of no significant variation in fish assemblage structure, by comparing 33 sites along the northern coast of the São Paulo State, Southeastern Brazil. Replicated stationary visual census samples (n = 396) were obtained at different distances from the coast, depths and wave exposures, including the mainland, three relatively small coastal islands, and the two margins of a wide channel between the mainland and the large São Sebastião Island (~350 km²), totaling 225 h of SCUBA diving. The regional rocky shore fish fauna comprised 106 species (41 families), with preponderance of diurnal mobile-invertebrate feeders. Samples from the outer margin of the São Sebastião Island, together with those from Alcatrazes, Búzios, and Vitória islands were significantly dissimilar from samples from the coastal sites at the São Sebastião Channel. Species richness tended to increase in a gradient from the coast to the more offshore islands. Local conditions such as depth and other habitat characteristics also influenced fish assemblages' structure. Distance from coast and depth were the main predictors for fish assemblages, followed by water transparency, temperature and benthic cover. This study represents the first regional-scale assessment of fish assemblages associated with rocky reefs in the São Paulo State coast, filling a major geographic knowledge gap in the South Atlantic. As the study region is experiencing fast coastal development and growing threats from seaport expansion, oil and gas exploitation, as well as increasing fishing and tourism pressure, the understanding of the underlying factors that influence the distribution and abundance of the reef-associated biota comprises a relevant baseline for monitoring, conservation planning and management.

Em um estágio preliminar os valores dos percentis 75 da precipitação decendial foram georeferenciados, permitindo a utilização de técnicas da geoestatística para proceder à interpolação dos dados. Modelos experimentais de semivariogramas padronizados foram obtidos, utilizando-se a variância amostral como fator de escalonamento, permitindo a verificação de proporcionalidade entre os modelos e agrupando-os sob a mesma tendência. O modelo teórico exponencial foi o que melhor se ajustou aos semivariogramas experimentais, seguido pelo modelo esférico. Os parâmetros estimados para os modelos, efeito pepita, patamar e alcance foram utilizados para a realização da krigagem e confecção dos mapas de isolinhas. A distribuição espacial dos percentis 75 da precipitação decendial reflete o comportamento da circulação atmosférica no Estado, apresentando alta variabilidade. As regiões oeste , sudoeste e noroeste  apresentaram as menores intensidades de precipitação e foram variáveis de acordo com os níveis temporais na primavera. A região litorânea apresentou as maiores intensidades de precipitação para quase todos os níveis temporais estudados, diferenciando-se das demais regiões do Estado. A exceção foi à região nordeste no final da primavera que apresentou valores de intensidades maiores do que os registrados no litoral. A faixa litorânea apresentou comportamento homogêneo, detectado pelo forte agrupamento das isolinhas em quase todos os decêndios analisados.  UNITERMOS: precipitação decendial, semivariograma, geoestatística, krigage.   GOMES, B.M., CRUZ, R.L. SPACIAL BEHAVIOR OF TEN-DAY PRECIPITATION 75 percentil FOR SÃO PAULO STATE IN THE SPRING2 Abstract  In the present study it was evaluated the ten-day precipitation 75 percentil spatial distribution for São Paulo state, using a total of 136 pluviometric stations with series over 27 year- records. In a preliminary phase, the ten-day precipitation 75 percentil  values were georeferred in the space, allowing geostatistics technique use for data interpolation proceeding. Experimental models of standardized  semivariograms were obtained  using  sample variance as a staggering factor, allowing the proportionality verification among the models and grouping them under the same tendency. The exponential theorical pattern was better fitted to the experimental semivariograms, followed by the spherical pattern. The parameters measured for the models, nugget, sill and range effect were used to carry out the kriging and isogram maps preparation. The ten-day precipitation 75 percentil  spatial distribution reflects the atmospheric circulation behavior in the state, presenting high variability. The  western, southwestern and northwestern regions presented the lowest precipitation intensities and varied according to seasonal levels in the spring. The coastal region presented the highest precipitation intensities for almost all  studied seasonal levels, differing from other state regions. The exception was the northeastern region at the end of the spring, which presented higher intensity values than those recorded in the littoral.  Key words: ten day precipitation, semivariogram, geostatistics, kriging.

ABSTRACT Objective: To analyze the spatial distribution of Tuberculosis cases with Mental Disorders, identifying factors that determine its occurrence. Method: Ecological study, conducted in the municipalities of São Paulo State. Secondary data were used, with the incidence of Tuberculosis and Mental Disorders as dependent variables in the years 2012 to 2015 and independent variables, socioeconomic, health and income transfer data. The Geographically Weighted Regression was applied in this study. Results: It was observed a distinct distribution between cases of Tuberculosis and Mental Disorders in the municipalities of São Paulo State. Among the explanatory factors, the Primary Care Coverage, population of freedom and income inequality were spatially associated with Mental Illness (R2= 0.12); Alcoholism (R2= 0.12) Illicit Drugs (R2= 0.50) and Smoking (R2= 0.50). Conclusion / Final considerations: The study advances in knowledge by evidencing the spatial distribution of cases of Tuberculosis and Mental Disorders, evidencing the determining factors for its occurrence in São Paulo State.
