Preferência alimentar da formiga urbana Camponotus vittatus forel (Hymenoptera: Formicidae)

For an adequate management program of urban ants, knowledge on their biology is required, with the aim of detecting and exploring their vulnerabilities. This type of information has been used in the manufacture of baits, which must show, among other characteristics, attractiveness to several species to be considered efficient and economically viable. Therefore, the present study was aimed to evaluate in the laboratory the attractiveness of sweet and fatty substances to Camponotus vittatus, trying to find which substances would be more efficient to be introduced as the attractive component in baits. Five colonies, 68 sweet substances and 23 fatty substances were utilized in the laboratory trials. The most attractive sweet and fatty substances, were, respectively, 75% demerara sugar and vegetable fat. When substances of both natures were tested together, sweet substances presented slightly higher attractive indexes than oily substances.

Mirmecofauna em um fragmento de floresta atlântica urbana no município de Marília, Brasil

The aim of this study was to verify the influence of the habitat fragmentation on the Ant Fauna in an urban fragment of Semideciduous Seasonal Atlantic Forest located in the municipality of Marilia, São Paulo, Brazil. The studied fragment was divided into three environments in relation to edge: "Edge" (2m), "Transition" (30m) and "Interior" (90m). By using pitfalls traps and attractive baits there were done nine samples between November 2007 and February 2008. There were collected 3.873 individuals distributed into five subfamilies, 19 genera and 33 species. Five species were abundant on three studied environments: Ectatomma sp1, Mycocepurus goeldii, Paratrechina sp1, Pheidole sp2, Trachymyrmex sp1, Wasmannia auropunctata. The edge and transition environments presented the lower Simpsons diversity index and higher species dominance. However, it was observed little variation between these parameters between environments. Faunistic similarity between environments, expressed by Jaccard's similarity index showed high similarity between all studied environments. Because the studied site is an urban fragment, the similarity found between these areas can be related to habitat fragmentation process, an historical of constant anthropic perturbation and low local colonization rates. However, we suggest that a posteriori evaluation should be done with other arthropods groups like spiders and beetles in due to understand the changes that occur in urban fragments and support the choice of conservation and management actions in favor of this important forest remnant localized in urban area of Marilia, São Paulo, Brazil.

Avaliação da população canina da zona urbana do Município de Araçatuba, São Paulo, SP, Brasil

Planning control programs, for diseases such as rabies requires information on the size and structure of the dog and cat population. In order to evaluate the dog population of the urban area of Araçatuba city, S. Paulo State, Brazil, a survey was conducted using a questionnaire to interview members of households. Eighty-eight districts were visited (37,778 houses) and the interview was possible at 77.93% of these. Human population size evaluated was 113,157 inhabitants. Houses that owned animals represented 55.2%, 26,926 of the animals concerned were dogs and 5,755 were cats. Of the dogs, 56.64% were 1-4 year olds and males represented 56.2% of the total population. Dog: person ratio was estimated at 2.8 dogs to every 10 persons, almost 3 times the ratio hitherto estimated and used in the planning of rabies vaccination campaigns.

Indicadores de floresta urbana a partir de imagens aéreas multiespectrais de alta resolução

The present work evaluated urban forest indicators, acquired through airborne high-resolution multiespectral images, on the quality of the urban design and its vegetative fraction, in special its trees, in nine neighborhoods of Piracicaba, SP. There were made supervised classifications for characterization of intra-urban elements and the proportions obtained, as exposed soil, tree cover, lawns, asphalt, concrete pavements and roofs. They were studied for the measurement of the urban forest in each place. These variables were related to each other, as well as with the independent variables: population density, people with more than fifteen years of study and family heads with income above twenty minimum wages, obtained through population census. Through the analysis of linear regression variables were identified for intra-urban areas evaluation. Correlations were made and linear regressions among the data obtained from the image and among the proposed indicators. Negative correlations were obtained among population density and arboreal covering and the evaluated indices, in accordance with the predicted in the literature. Composite indicators are proposed, as: the proportion between arboreous space on waterproof space (PAW) and the proportion between arboreous space on building space (PAB). It is concluded by the possibility of the use of those indicators for evaluation of the urban forest and definition of priorities in the execution of ordinances to the improvement of the urban forestry, being prioritized the application of resources in the most lacking neighborhoods.

Avaliação de fatores de risco de cães sororreagentes à leptospira spp. e sua distribuição espacial, em área territorial urbana

We aimed to evaluate the risk factor of serum reactive dogs to antileptospire agglutinin and their spatial distribution in an urban area. We collected 1,000 blood samples from dogs at 20 immunization centers, homogeneously distributed in the urban area (32 km²) of Botucatu, Sao Paulo, Brazil. Diagnosis was made by microscopic serum agglutination using 24 serovars of Leptospira spp. Statistical analysis was performed by Goodman's test with 5% of significance. Spatial clusters were tested by spatial scan statistic using SaTScan. We found that 17.9% dogs reacted to Leptospira spp. (p<0.0001). Dogs with street access (22.14%) were more reactive (p<0.05) than those without (14.83%). The scan test indicated only one significant cluster influenced by age. Incorporating each one of the co-variables gender, breed, and street access to age, we found that street access was the most important. Street access and age were the most important risk factors in the large number of reactive animals in the cluster, with the castellonis serovar being the most reactive in urban dogs. The identification of a cluster with more reactive dogs than expected allows local preventive measures to be taken.

Investigação soroepidemiológica de leptospirose canina na área territorial urbana de Botucatu, São Paulo, Brasil

Leptospirosis was seroepidemiologically investigated in 775 dogs from Botucatu, state of Sao Paulo, in blood samples collected during the annual anti-rabies vaccination campaign. The samples were collected from 14 out of the 45 vaccination stations geographically distributed in five different municipal districts, with a territorial urban area of 31Km2. Samples were taken from 449 males and 326 females; 564 were of undetermined breed, and 211 were pedigree animals; ages ranged from 3 months to 20 years. Diagnosis included the microscopic serum agglutination tests using 12 Leptospira spp serovars. Serological results and epidemiological variables were compared using Goodman and chi-square tests, with χ=0.05. There were 119 (15.3%) positive samples for 11 serovars; the most important was canicola with 48 (40.3%), followed by pyrogenes 41 (34.5%). Statistical analysis showed significant difference for: breed, 17.7% positive in undetermined breeds and 9.0% in pedigrees; and sex, 18.4% positive in males and 11.0% in females. There was no statistically significant difference in relation to age with uniform distribution of positives.

Hidrogeoquímica do aqüífero guarani na área urbana de ribeirão preto (SP)

This work evaluated the hydrogeochemistry of the Guarani Aquifer in the urban area of Ribeirão Preto, São Paulo State. Thirty one sampling points were established and it was carried out field campaigns in 7 and 8 July 2005, analyzing the following parameters: conductivity, temperature, pH, turbidity, color, dry residue, dissolved oxygen, Ca2+, Mg2+, Na+, K+, Fe3+, Al3+, HCO3-, SO42-, PO43-, NO3-, Cl- and F-. The results indicated that the groundwaters in the urban area of Ribeirão Preto pH possess slightly acid, low conductivity, turbidity, color and dissolved oxygen inside the limits established for drinking waters. The ionic composition indicated that the groundwaters have low cations and anions concentration, being they classified as soft water and calcium-bicarbonated. Statistical tests suggested that conductivity and pH are controlled for the calcite dissolution (CaCO3) during the water/rock interaction process. Besides, it is possible to conclude that the high NO3- and PO43- concentrations found in the groundwater in the urban area of Ribeirão Preto are originated due to anthropogenic activities.

Enclaves fortificados e segregação urbana: o caso de Jundiaí

The article discusses the spread of closed condominiums in Jundiaí (SP). The studies about this phenomenon have predominantly focused on metropolitan areas; therefore, the relevance of research on medium-sized cities in order to identify similarities and differences among different urban scales. The main objective was to investigate the spacing phenomenon of closed condominiums as a housing pattern tendency as well as its social, urban and environmental impact. This study encloses the period from 1970 to the present.

Dinâmica regional e política urbana: Uma análise das cidades de porte médio da região administrativa de Campinas/SP

The process of internalization of development occurred in the state of Sao Paulo resulted in accelerated growth of intermediate cities leading to a pattern of development with sprawl, segregation and suburbanization. In this process stands the Administrative Region of Campinas, the hinterland region of higher growth and accumulating a larger number of medium-sized cities. Such questions imply the need for appropriate urban policies to confront these challenges, under risk to jeopardize the quality of life and environment of these cities. The implementation of the Estatuto da Cidade brings new perspectives for urban management in medium-sized cities. This study aims to evaluate the deployment of instruments of urban management in medium-sized cities in São Paulo, with emphasis on Administrative Region of Campinas, based on the Profile of Brazilian Municipalities 2008 conducted by IBGE. The results point to a worrying situation, as it did not see a correlation between the deployment of these instruments and the size, growth and income in the mid-sized cities.

A qualidade ambiental urbana na legislação municipal: exemplo do plano diretor de araçatuba-SP 1

Environmental quality is a fundamental issue in order to characterize quality of life in the cities. The human activities interfere in environmental processes, causing impacts that must be minimized. It is the task of municipal laws to impose theoretic and practical foundations appropriated to the dimension of local problems. In this sense, the goal of this work was to propose a discussion about the recognition of environmental quality in municipal law, especially in the Municipal Master Plan of Araçatuba, city located in the state of São Paulo. It was possible to observe that in many aspects this law is far away from urban reality.

Análise da compacidade do solo na área urbana de Bauru/ Estado de São Paulo utilizando Ensaios de Penetração Padronizado e sísmica de refração

This study was done to determine compactness of soil strata in the urban area of Bauru, central São Paulo State using standard penetration test (SPT) and seismic refraction methods. Frequency distribution within boreholes was measured every meter to a depth of 30 meters. The geometric mean of standard penetration test values was computed every meter. A biplot graph showing the relationship of SPT with depth indicates soil stratification. In addition, five sections of seismic refraction values, which also indicate the compactness of soil strata, were obtained. A comparison of the two methods shows significant correlation between the results obtained from each.
