Dinâmica da vegetação de uma floresta paludosa no município de Rio Claro - SP

Swamp forests, are laid down in the lowlands, with almost permanent presence of water on the soil surface and generally occupy portions fairly flat. In 2003 a phytosociological survey was conducted of the tree and shrub component of a swamp forest established on a steep slope in Rio Claro - SP, through the use of 45 permanent plots of 10 mx 10 m (0.45 ha) divided into three blocks: 1, 2 and 3. The present study aimed to review these plots and discuss the dynamics of vegetation in the swamp forest in question period of eight years. Altogether 1529 individuals were found alive, belonging to 29 families and 47 species. It can be observed that there was a decrease of one family (Flacourtiaceae) and two species (Xylosma tweediana, Inga marginata) in relation to 2003. In general there was a loss not only in number of individuals, but basal area and species diversity. The Block 1 was the only one to show a positive balance in terms of numbers of individuals (2.75%); in Block 2, there was little variation (1.72%) which is negative; whereas Block 3 had the largest decrease, 19.18%. The mortality rate (2.74% / year) for the community remained higher than the recruitment (1.81% / year). There was a decrease (3.19%) of total basal area of the sample relative to 2003, with the highest relative dominance by Calophyllum brasiliense. The decline in diversity of species could be evidenced by the Shannon index, which was 2.0 nats.individual-1 and evenness of 0.52. The most important species (IVI) were Euterpe edulis, Calophyllum brasiliense and Magnolia ovata, together accounting for 59% of IVI community. High mortality and low recruitment rates indicate disturbances in the community, some factors such as proximity to roads, the different soil types associated with a high rate of water saturation and the declivity are crucial to the balance within the community

Subsídios para elaboração de plano municipal de gestão de resíduos sólidos orgânicos para o município de Rio Claro-SP

The research aims to propose grants for development of Municipal Plan for the Management of Organic Solid Waste generated in the municipality of Rio Claro. The research universe was composed of organic waste generators establishments (markets and grocers). From the registry of commercial establishments provided by the municipal government were identified who presented this typology, which totaled 38 establishments. In this universe the interview was conducted in 15 establishments obtained by directed sampling based on the characteristics of size, type and location. The data collected were the amount generated, disposal of waste, waste separation, collection frequency, reasons for the disposal of waste, frequency of purchase of products. From the data obtained in the field, we estimated the total generation of organic waste in this segment for the municipality. Then, the estimated costs for implementation and operation of a composting center, a way to subsidize the implementation of the management plan was carried out. We opted for the aerobic composting process by the simplicity of operation and because it is a technique already known. The average waste generation was established by tracks (size) with: stores up to 4 boxes (classified as small) generate on average 1511 kg / month, 40% of organic waste, the 5-9 boxes (small/midsize) generate on average 4338 kg / month, 35% organic and the 10 to 19 boxes (midsize) generate on average 7647 kg / month with 32% organic. In total establishments generate 105 t/ month of waste, with 35t / month of organics. 94% of establishments are in font segregation of waste into recyclable, organic and waste, indicating that the proposed management of organic waste is amenable to application without many changes in existing routine in stores. Recyclables are sent for recycling through selective collection held by the cooperative, while the organics are destined for the landfill and feed. The results indicate...

Geofísica aplicada no diagnóstico preliminar do antigo lixão do município de Rio Claro - SP

The issue of solid waste disposal and urban growth are conflictive, since the areas where old uncontrolled refuse disposal were away from the city today are incorporated to the urban area population. Thus, now population is closer to the degradation of contaminants coming from waste disposal, and, in some cases, these areas become housing subdivisions. This work aims to support the diagnosis of a former landfill in the municipality of Rio Claro (SP), using geophysical methods through resistivity anomalies. In order to develop the diagnostic, it was utilized water and soil analysis of a preliminary report and techniques of vertical electrical sounding and electrical profiling. The areas influenced by the garbage presented less resistivity than the one of the natural subsoil. Through the interpretation of results, the local potentiometric map was elaborated, as well as a map of calculated resistivity. The interpretation of these products indicated a disagreement between the groundwater flow and the current topography, leading to an identification of a preferential direction of the contamination plume in the NE-SW. These observations prove the applicability of geoelectrical methods in areas of former waste disposal with little information.

Ambiente percebido e sua associação com a atividade física total no lazer em adultos residentes no município de Rio Claro, SP

Introduction: Given the repercussion of the important role of physical activity in the prevention of sickness and non-communicable diseases / loss, many works have been done in order to understand the association of sociodemographic characteristics with sedentarism. The elements which influence the physical activity practice are countless. Besides the intrapersonal element, environment elements (social environment, cultural environment, public politics, information environment, natural environment etc.) are also important in the life style. Yet, the way that the person understands the environment can be considered in the planning of the strategies to change the sedentary behavior. Objective: Verify the association of the environment perception with the practice of physical activity (FA) at leisure time in adults living in Rio Claro – SP. Methodology: The sample consists of 470 adults, all residente in rio Claro-SP, aged ≥ 18 years old. The chosen participants answered to the questionnaires: Neighborhood Environmental Walkability Scale (NEWS), International Physical Activity (IPAQ) and to a specific questionnaire with personal data (age, sex, educational level, economical level, weight, height and marital status).

Prevalência e fatores associados à inatividade física em escolares do ensino médio das escolas do município de Rio Claro - SP

Cerca de um terço do total de doenças em adultos estão associadas a condições ou comportamentos que começaram na juventude. No Brasil, a porcentagem de Inatividade Física (IF) nos adolescentes varia entre 29% a 94%, que é um dado alarmante, pois esses adolescentes provavelmente serão adultos inativos fisicamente e com um risco maior de adquirirem uma doença de agravo não transmissível. Desse modo, o objetivo do estudo foi verificar a prevalência e os fatores associados à IF em escolares do Ensino Médio do município de Rio Claro- SP. Estudo do tipo transversal, de base populacional, realizado no primeiro semestre letivo de 2009 contou com a participação de 467 alunos (213 homens e 254 mulheres) das escolas particulares e estaduais do Ensino Médio do município de Rio Claro-SP. Para avaliar o de nível de Atividade Física (AF) dos adolescentes foi utilizado o Physical Activity Questionnarie-Children (PAQ-C). Foi aferido a circunferência de abdômen e calculado o Índice de Massa Corpórea (IMC). Os pais responderam um questionário para avaliar o nível de AF através do International Physical Activity Questionnarie (IPAQ) e o nível socioeconômico. Para verificar a associação entre as variáveis (sexo, nível socioeconômico, IMC e circunferência de abdômen) com o nível de AF dos adolescentes foi realizado a Regressão Logística e para verificar a associação entre o nível de AF dos adolescentes e dos pais foi realizado o Teste Qui-Quadrado. A prevalência de IF dos adolescentes foi de aproximadamente 83% e, dentre as variáveis analisadas, apenas sexo mostrou-se significante (p=0,00), sendo o sexo feminino com maior chance de IF.

Avaliação do gerenciamento e disposição final dos resíduos químicos de laboratórios do IGCE, UNESP - Rio Claro/SP

Laboratory of Chemical Waste Management programs are being implemented in various universities of the country and the world, in recognition of the urgent need to change the reality of disregard for the environment, together with objective responsibility of the generator, and especially the awareness of sustainability. Analysis and research laboratories involve a range of waste in developing their studies with intrinsic characteristics related to their form of generation. The amount of waste generated in this segment is negligible compared to industrial activities, but the environmental issue is that these residues do not have a standard technique for treatment due to the potential variation of its composition. This research project, aiming their suitability and continuous improvement, aims to diagnose and analyze the current situation of the management and disposal of chemical waste generated by the laboratories IGCE UNESP, Campus Rio Claro / SP.

These proposals based on prevention and corrective control, where the preventive approach aims at lifting techniques and actions to reduce the generating sources and...

Análise de ocorrências dos impactos pluviais na área urbana de Rio Claro (SP)

The Urbanization is a notable process in our society, being part of it since around 3500 BC in Mesopotamia, currently Iraq area. Since the Industrial Revolution, cities had a significant increase in their growth and began to concentrate increasingly labor and capital. Brazil, despite having had a late industrialization, also had a high population growth in cities, especially in the XVIII century, which were not provided with any kind of planning that targets the ordering and implementation of the urban essential apparatus. Therefore, Brazilian cities started to exhibit countless structural and environmental problems. Associated with inadequate infrastructure, the modifications in the urban atmosphere, like increased heat, air pollution and increased rainfall and storm frequency, cause different types of impacts in cities. Among the most worrisome are those from the intense rain, which cause human and material damage. The city of Rio Claro (SP) can be considered an example of this reality. Thereby, the objective of this study was to analyze the impacts on the population originated from rainfall in the urban area during the period 2005-2010, by the mapping of events and analysis of the active atmospheric systems. The information of the events were collected in the Fire Department and the Press and the synoptic maps were obtained in the library of INPE, in Cachoeira Paulista (SP) and in the site of the Navy of Brazil. The data showed that among 247 occurrences, during the six years, 233 occurred in the spring-summer period. Moreover, after finalizing the maps, it was found the locations considered critical regarding the frequency of occurrences, as: Visconde do Rio Claro Avenue and central area of the city, both with a total of 23 occurrences; Jardim Inocoop, with 20; Tancredo Neves Avenue, with 12 and Vila Paulista, with 10 occurrences. Through the graphs, it was found that the most recurrent atmospheric system, during the studied period, is...

Relação solo-paisagem em um transecto da depressão periférica e do planalto ocidental, região de Rio Claro (SP)

As unidades de paisagens naturais se diferenciam pelo relevo, clima, cobertura vegetal, solos ou até mesmo pelo arranjo estrutural e do tipo de litologia. A caracterização pedológica e o entendimento das relações entre pedologia, geologia e geomorfologia são importantes para a compreensão da distribuição dos solos numa paisagem. Considerando esta como sendo uma combinação dinâmica e instável de elementos físicos, biológicos e antrópicos, e estando em constante evolução, realizou-se o estudo das características químicas, físicas, mineralógicas e morfológicas das coberturas superficiais de uma mesma Unidade Fisiográfica na região do Planalto Ocidental e da Depressão Periférica Paulista nas proximidades de Rio Claro – SP, para a compreensão de suas relações genéticas e cronológicas na evolução das paisagens da área. Para isso foram comparados os solos de dois transectos dentro dos compartimentos, levantando e analisando as características citadas para que se possa obter informações que permitiram o diagnóstico da evolução da área, visando contribuir para o avanço das coberturas superficiais e sua relação com a evolução da paisagem. Foi possível compreender determinados processos e produtos que deram origem às coberturas superficiais e consequentemente a algumas paisagens representativas da Quadrícula de São Carlos a partir dos métodos empregados. O estudo das coberturas de alteração intempérica da região centro-oeste paulista, e seu reconhecimento, são fundamentais para o ordenamento territorial e seu planejamento regional

Geotecnologias para a análise da bacia hidrográfica do Córrego Wenzel - Rio Claro/SP: proposta de gestão de recursos hídricos

The expansion of urban in medium-sized citie, increase the importance of action planning and management of natural resources, among which water is the most important. Such action should include the integration of physical and man-made elements involved. In this context, it becomesimportant for watershed analysis and the use of geotecnologies. Thus, the objective was to demonstrate the contribution of the geo, as a tool for managing a river basin, allowing the integration of physical data and the analysis of anthropogenic environmental scenarios in urban areas. The area chosen, the basin of the Wenzel, is located in Rio Claro / SP, a city whose urbanization process has been intense and continuous. Thematic maps were generated from the physical environment: soil, slope and geological, as well as maps of land use. With regard to land use maps, these were drawn from the visual interpretation of material aerophotogrammetric, considering the years 1995 and 2010, performing an evolutionary analysis. It was observed that the area presents small variation in the physical and structural aspects, with lithological and geomorphological formation favoring the occurrence of floods, erosion and siltation. These processes are accelerated by the forms of land use, with intense urbanization during the period between 1995 and 2010, and poor preservation of permanent preservation areasand. In the floodplain areas there is a high waste disposal is the most notable environmental problem

Avaliação da vulnerabilidade a contaminação das águas subterrâneas do aquífero Rio Claro na mineração Mandu, distrito de Ajapi - Rio Claro-SP

Groundwater in the Rio Claro district is predominantly extracted from low productivity wells on the Itararé Aquifer, from depths greater than 150 m. These factors in conjunction with increasing demand for water supply have stimulated many industries to exploit the Rio Claro Aquifer, constituted by Cenozoic sediments of the Rio Claro Formation, where hydraulic properties are poorly known. For this reason, it is necessary to study the possible vulnerable to contamination punctual locations of the aquifer, in order to enable proper management of these groundwater reserves and to allow continuity of supply. Thus, this study aims to assess the vulnerability to groundwater on contamination Rio Claro Aquifer, punctually in Mandu mining site area, located in the District of Ajapi, Rio Claro - SP, the company which operates and sells industrial sand. The risk of groundwater contamination depends on the relationship between the hydrogeological characteristics of the aquifer layer (vulnerability to contamination) and the pollutant load. To evaluate the susceptibility to contamination it was applied the method GOD (FOSTER and HIRATA, 1987; FOSTER et. al., 2002) and, in addition, field and laboratory tests were performed to chacacterize the granulometry of the strata, hydraulic conductivity and some physical indices to make the evaluation more assertive and detailed. Punctual contamination vulnerability found in the aquifer Rio Claro, was moderate, which means that the aquifer is vulnerable to some contaminants, but when continuously discharged or leached. Thus, Mandu mining has a great role on preventing the emission of contaminants in the process of extraction and processing of sand... (Complete abstract click electronic access below)

Inventário de abelhas solitárias (Hymenoptera: Apoidea) com o auxílio de ninhos-armadilhas no campus da Unesp de Rio Claro - SP

As abelhas solitárias são caracterizadas pela independência da fêmea em construir e aprovisionar sozinha seus ninhos, sem auxílio, cooperação ou divisão de trabalho entre as fêmeas de uma mesma geração, ou entre mãe e filhas. Dentro deste grupo, se enquadram aquelas que nidificam em cavidades pré-existentes. O objetivo deste trabalho é inventariar as espécies de abelhas solitárias no Campus da UNESP de Rio Claro - SP com o auxílio de ninhos-armadilha. Para este estudo foram escolhidos quatro locais, e em cada um foram expostos 212 ninhos-armadilha, confeccionados com cartolina preta, fechados numa das extremidades, todos com o mesmo comprimento, porém diferentes quanto ao diâmetro: 12,0 x 0,6 cm (ninho pequeno, NP) e 12,0 x 0,8 cm (ninho grande, NG). Esses ninhos foram arranjados dentro de tubos de PVC e apoiados em prateleiras ou em troncos, sempre a 1,40 metros de altura e protegidos contra o sol e chuva. A amostragem dos ninhos foi realizada no período entre maio de 2009 e abril de 2010, com coletas a cada dez dias. Cada ninho retirado foi reposto para manter o número de ninhos disponíveis. O período de emergência foi acompanhado de maio de 2009 a agosto de 2010. Apenas um ponto de amostragem houve coletas de ninhos de abelhas, o “Sítio de Nidificação”, com nidificação de sete espécies de abelhas pertencentes às famílias Apidae, Centris (Hemisiella) tarsata, Centris (Heterocentris) analis, Tetrapedia curvitarsis e Tetrapedia diversipes, e Megachilidae, Carloticola sp., Epanthidium tigrinum e Megachile sp. A espécie mais abundante foi Tetrapedia curvitarsis, seguida por Centris (Heterocentris) analis e Tetrapedia diversipes. A construção de ninhos foi maior durante o período chuvoso, havendo no mês de fevereiro de 2010 maior abundância de nidificações (23%) assim como maior riqueza de espécies nidificando (n = 6). Neste mesmo mês também... (Resumo completo, clicar acesso eletrônico abaixo)
