Arraias em rios da região Sudeste do Brasil: locais de ocorrência e impactos sobre a população

INTRODUÇÃO: No presente trabalho objetivamos descrever o processo de colonização da Bacia do Alto Paraná, Sudeste do Brasil, por arraias, demonstrando sua atual situação e provável tendência, os impactos gerados e discutindo algumas ações de manejo e medidas mitigadoras. MÉTODOS: Foram realizadas entrevistas com ribeirinhos e profissionais de saúde para o levantamento de informações sobre a ocorrência de arraias e acidentes associados a estes animais, além de coletas e observações subaquáticas de potamotrigonídeos, entre 2004 e 2009, em localidades situadas nos Estados de São Paulo, Paraná e Mato Grosso do Sul, no Sudeste, Sul e parte do Centro-Oeste do Brasil. RESULTADOS: Três espécies de arraias foram identificadas na área de estudo, demonstrando utilizar os caminhos abertos pela Hidrovia Tietê-Paraná para se dispersarem. Dezesseis vítimas de acidentes envolvendo esses animais foram encontradas, notadamente banhistas e pescadores, chamando a atenção pelo fato dos casos não serem notificados e apresentarem elevada morbidade, com marcante incapacidade temporária para o trabalho. CONCLUSÕES: Este é o primeiro relato de invasão biológica envolvendo espécies de elasmobrânquios conhecido na literatura e, pelas arraias estarem colonizando áreas densamente povoadas e ampliando sua área de distribuição a cada ano, é de se esperar que sua interação negativa com humanos se intensifique, provocando alterações importantes no perfil epidemiológico dos acidentes por animais peçonhentos ocorridos no sudeste brasileiro.

Diagnóstico ambiental no período frio e seco do Córrego Bandeirantes, município de Rio Claro, SP: parâmetros físicos, químicos e físico-químicos

The present study was concerned with checking the water quality, the recovery of the riparian vegetation and vegetation around the springhead of stream Bandeirantes, such as the inadequate disposal of waste along this stream, which is located in Rio Claro, SP, in the period from March to July of 2010. Aiming to propose mitigation measures to reverse the degradation processes and develop activities to help a better awareness of the population directly related to this water resource. The water quality was analyzed by performing monthly sampling in three different points along the stream. The first point of sampling is in the spring of the stream, the second at the region called estradão and the third near its mouth, when it flows into the Ribeirão Claro, a tributary of the right bank of the Corumbataí river. It was calculated from the Water Quality Index (WQI) developed by Cetesb. The results were compared with current law. The riparian vegetation, which is responsible for the protection of rivers and streams, was observed and examined during the field work. The results indicated the stream as class 2 and the WQI has been classified, in the most of the analysis, such as a water of good quality. However, some parameters showed a worrying situation and highlighted the current situation, with waste deposits, furniture and animal waste into the pit of the stream studied

Avaliação ambiental em empresas do distrito industrial Antônio Crepaldi, Presidente Prudente/SP

The sustainable development is the center of many discussions about the environment, economy and society. Environmental issues bring out problems with the fauna and flora, water resources, land use, population growth, residues, basic sanitation, and others. In this sense, the aim of the present work was to develop an environmental diagnostics and propose measures to mitigate the most significant environmental impacts generated by four enterprises in Antonio Crepaldi Industrial District, located at the city of Presidente Prudente/SP. In the study, it was used the methodology proposed by Moreira (2006), and it was done the following activities: monitoring and analyses of the production process, identification of potential environmental aspects and impacts; assessment of the impacts according to its nature, relevance and significance; proposition of measures to mitigate the critical impacts. As a final result, it was obtained an environmental diagnosis about the situation of each of the four companies studied, and it was possible to know the level of criticality of the impacts in each one, and proposing mitigation measures to control or minimizing them, bringing many benefits to the organization

Análise das enchentes no estado de São Paulo durante a operação verão de 2000 a 2007

With increasing frequency and intensity of climate disasters in Brazil, it is necessary studies on mitigation measures. From this spatialization of areas considered risk becomes essential to assist the public in preventive plans. Floods and flooding are the main types of climatic disasters that hit our country, especially the state of Sao Paulo, mainly by self degree of urbanization. From the data provided by the State Civil Defense was possible to create a database with the localities georelacional occurrences of flooding in the state in which through techniques of GIS (Geographic Information System) enabled the interrelationship and spatialization occurrence of areas affected This will help to determine potential areas of risk and different ways to prevent these disasters

Diagnóstico ambiental da área de influência do distrito industrial de Rio Claro - SP

Economic activities, whether large or small, can cause a range of environmental changes, not always reversible, harming society and its quality of life. Many potentially polluting activities have already been installed in various Brazilian cities, just as at the industrial district of Rio Claro / SP, which allow the synthesis of the many environmental impacts. In this sense, this report aims to make an environmental assessment in the influence area of the industrial district of Rio Claro / SP, located in the urban area of the city. As a result, the existence of prior related studies was observed, especially the diagnosis and study of the many implications that arises from activities impacting, and further, there was a demarcation of the influence area of the district and its derivatives impacts in the influence area, the steps of prediction and mitigation measures and if these activities meet the minimum technical requirements in planning and environmental applicable legislation.

Monitoramento hidrossedimentlógico da bacia hidrográfica do alto rio Sucuriú (MS) contribuinte da PCH Costa Rica

The growing demand for electricity in Brazil has stimulated the implementation of Small Hydro Power (PCH) in various regions of the country. However, the silting of reservoirs is a major problem faced by power plants and power plants. In this context, this study aimed to evaluate the data hydrosedimentological strategic points of the watershed of the Alto Rio Sucuriú (MS) to identify the possible causes siltation of the reservoir PCH Costa Rica and suggest mitigation measures. Hydrosedimentological surveys were conducted during the rainy season (February / March 2012) and drought (August 2012), and obtained data flow, discharge liquid, suspended solids and bottom and organic matter content. Based on these results it was determined that the points 2, 4, 7 and 9 are the largest contributors to sedimentation, and point 4 got most liquid discharge (38,20 m3s-1), point 7 largest discharge of solid suspension (906,3 mg L-1), points 2 and 4 major discharges solid totals (231,59 t dia-1 and 238,185 t dia-1 respectively) and point 9 higher organic matter content (22,18%) . Found greater fraction of fine sand and very fine suspended solids and solid medium sand in the background. As mitigation measures for the process of silting of the reservoir PCH Costa Rica (MS) highlights the orientation of landowners in adopting conservation measures and planting of leguminous species native to the region in symbiosis with nitrogen-fixing bacteria

Road-kills of the giant anteater in south-eastern Brazil: 10 years monitoring spatial and temporal determinants

Context. The giant anteater, Myrmecophaga tridactyla, is a large insectivorous mammal from Cerrado which is classified as vulnerable by the IUCN's red list. In spite of frequent giant anteater casualties, there continues to be a lack of published data on how road and landscape attributes affect road-kill rates - information that could prove useful in guiding mitigation measures.Aims. We seek to determine whether road and landscape attributes influence the incidence of road-kills of the giant anteater.Methods. From February 2002 to December 2012 (except for 2004), five roads in two regions in south-eastern Brazil were surveyed twice each month by car. We recorded temporal road-kill data for the giant anteater and related spatial road variables. These variables were also recorded at regular control sites every 2 km. We also took traffic volume data on stretches of the two roads to correlate with road-kills.Key results. Of the 45 anteater casualties recorded, there was a predominance of adult males. On roads MG-428 and SP-334, we found anteater road-kills were more common in the dry season, negatively correlated with traffic volume and related to the presence of native vegetation. Accordingly, road-kill sites tended to occur near the cerrado and grasslands and also appeared more frequently on some straight stretches of roadways. Although it was not shown to influence road-kill rates, topography data does point to regular overpass/underpass locations allowing population connectivity. Termitaria or ant nests were present at all road-kill sites, with 86% having signs of feeding.Conclusions. Native vegetation along roadways, together with straight road design, increases the probability of anteater road-kills by 40.1%.Implications. For mitigation, mowing and removing insect nests on roadsides, as well as roadside wildlife fencing in cerrado and grassland areas is suggested. Warning signs and radar to reduce vehicle speed are recommended for both human safety and anteater conservation. With regard to population connectivity, the absence of aggregated anteater road-kill data in this study meant that there were no particular crossing locations identified. However, the collected topography data do show places that could be used for roadway crossings. The measures indicated may apply to similar species and types of topography on other continents.
