Chironomidae (Diptera) associado à Eichhornia azurea em seis lagoas marginais ao rio Paranapanema, SP

The family Chironomidae is one of the most important groups within the macroinvertebrate communities, both in density and in richness, and because of its high adaptive value, has a wide distribution on the planet. These and other more specific features of each genus allow the use of this group of biomonitoring studies in the aquatic ecosystem, however, primarily, it is necessary to inventory the aquatic fauna. Thus, this study aimed to evaluate the taxonomic composition of Chironomidae associated with Eichhornia azurea in six lateral lagoons of Paranapanema River, where only five of them have very little information about the aquatic fauna associated with floating macrophytes. Furthermore, we analyzed the influence of environmental conditions on the richness and density of this community. Samples (biotic and abiotic) were held in March and August 2009 on the Ivo, Carmo, Sete Ilhas, Barbosa, Poço da Pedra and Coqueiral lagoons, which are upstream of the Jurumirim Reservoir. Samples with an area of 0.1976 m2 were collected at three banks of E. azurea of each lagoon. Then, they were washed in formaldehyde and water and fixed in 70% alcohol. The identification of morphospecies recorded 38 taxa (32 in March and 37 in August), where the Ivo lagoon is the richest (27 taxa). The density of each group varied according to each pond and is generally Asheum sp., Chironomus sp., Beardius sp., Parachironomus sp., Labrundinia sp., Tanytarsus sp., Ablabesmyia sp. and Polypedilum sp. the most representative. Limnophyes sp., Denopelopia sp., Paratanytarsus sp. and Parametriocnemus sp. were genders in lower density. The Dominance index ranged between 0.1490 (Barbosa Lagoon in March) and 0.4114 (Poço da Pedra Lagoon in March), and the Diversity Index ranged from 2.08 (Coqueiral Lagoon in March) and 3.58 (Barbosa Lagoon in August). The concentration of dissolved oxygen and pH were the environmental variables most correlated with the groups ...

Efeitos do deplecionamento induzido do reservatório de Salto Grande, Rio Paranapanema(SP/PR) sobre as assembléias de microcrustáceos (Cladocera e Copepoda) de duas lagoas marginais

No reservatório de Salto Grande (22º53’53’’S / 49º59’33’’W), Rio Paranapanema (SP/PR), é realizado um tipo de manejo (redução do nível de água) para redução da biomassa da macrófita submersa Egeria densa desde 2004. Estas plantas causam perdas econômicas para o programa de geração elétrica e infortúnio para a população local. O reservatório de Salto Grande possui lagoas marginais que apresentam elevada densidade dessas macrófitas e são tidas como ambientes de alta importância para o desenvolvimento, alimentação e reprodução de muitas assembléias, principalmente as de microcrustáceos zooplanctônicos. O objetivo deste trabalho foi analisar as mudanças na estrutura (composição, riqueza, abundância e diversidade) das assembléias de microcrustáceos zooplanctônicos (Cladocera e Copepoda) e suas relações com as alterações nas condições limnológicas decorrentes da variação de nível em duas lagoas marginais (Pedra Branca e Guaritá) em função do deplecionamento. Foram realizadas amostragens mensais de abril/2005 a julho/2006, além de coletas nictemerais durante o processo de deplecionamento (agosto/05) e um mês após o mesmo. Para a análise do zooplâncton foram amostrados 150 litros de água superficial em cada lagoa (região limnética). Simultaneamente, foram medidas as variáveis físicas e químicas da água: temperatura, pH, oxigênio dissolvido, condutividade elétrica, transparência, turbidez, material em suspensão (total, frações orgânica e inorgânica) e concentração de clorofila a. As variáveis limnológicas demonstraram um padrão de variação sazonal, além da influência do deplecionamento, principalmente sobre a temperatura e oxigênio dissolvido. O valor de riqueza encontrado para Cladocera foi elevado, totalizando 49 táxons. Os Copepoda foram analisados apenas até o nível de Ordem... (Resumo completo, clicar acesso eletrônico abaixo)

Geologia das coquinas-reservatório do Campo de Pampo, Bacia de Campos

The Pampo oil field is located in the southwest of the trend Badejo-Linguado-Pampo in an accumulation of single - mixed trap: structural-stratigraphic-diagenetic. Its main reservoir is a coquina shell of bivalves (the lowest) in the Lagoa Feia Group. During the rift phase, the Badejo-Linguado-Pampo trend´s accumulations evolve according to three tectono-stratigraphic cycles. The first two cycles are formed by siliciclastic rocks with fining up sequences and carbonates coquinas bivalves. The youngest cycle related to Alagoas age is a transgressive event represented by the presence of an evaporitic layer in the top (anhydrite). This study aims to characterize the reservoir Coqueiros Formation based on the analysis of 2D and 3D seismic data and well data-correlation profiles. The structural map of the top of coquinas reservoir indicates a curvilinear contour of Pampo Fault as described on the literature. This fault was interpreted on seismic data as a basement´s high, and it doesn´t show influence on the horizons above the top of Lagoa Feia Group. The Pampo fault is responsible for the division of the field into two blocks: the hanginwall in the West and the footwall to the East. This division is well marked on the reservoir´s isopach map where a greater thickness of reservoir is observed on the lower block. In the Southeast extreme of Badejo-Linguado-Pampo trend, on Pampo Field, the thick siliciclastic´s interval ends laterally to the basement, and its lower´s cycle forms a wedge, as consequence the carbonate-coquina overlaps directly the basement. Another implication of the higher and distal position of Pampo field is that the third cycle is absent, truncated by the unconformity pre-Macaé Group (Albian)

O espaço em Água-mãe, de José Lins do Rego

O romance Água-mãe de José Lins do Rego é ambientado no Rio de Janeiro e foge, portanto, da temática característica do escritor - a sociedade e a região nordestina. Por conta dessa mudança de espaço, a crítica classifica o romance como uma obra não-regionalista e, por isso, de pouca importância na produção reguiana. Ao contar a história de três famílias que habitam a região de Cabo Frio, às margens da lagoa da Araruama, o escritor tematiza o terror do sobrenatural e a força do destino centrados em um lugar específico, provenientes dos malefícios da majestosa Casa Azul, supostamente responsável pelas diversas tragédias que acometem as personagens. O espaço, na obra, é de grande importância para que se crie o clima de mistério que aterroriza a todos. Por isso, o presente trabalho mostra, a partir de teorias sobre essa categoria narrativa, quais os artifícios usados por José Lins do Rego para construí-la e criar a atmosfera que toma a narrativa, o terror que amedronta as personagens de Água-mãe

Remoção de N-amoniacal em baixas concentrações de oxigênio dissolvido a partir do efluente de frigorífico bovino

This work aimed to develop a biological system for removal of ammonia nitrogen operating at low concentrations of dissolved oxygen. Thus, a biological upflow vertical reactor was built, in which the affluent pass through the support media until the top. Sludge from an anaerobic stabilization pond of a slaughterhouse unit in the city of Presidente Prudente - SP was used as inoculum. Initially the system operated in batch and afterwards in a continuous flow with different HRT. For feeding the reactor, an initial phases was adopted a synthetic culture media, described by Martins (2007), in order to establish the ideal conditions for the development of Anammox bacteria and subsequently, submitted to the system a slugde effluent of slaughterhouse. The results showed significant removal efficiency of N-NH4+, especially in the phase without recirculation of culture media, with an average of 71% removal, with the proportion of removal of N-NH4 +:N-NO2- average 1: 1,69. For the period of operation with effluent from the slaughterhouse, were not obtained satisfactory results, without confirmation of the proliferation of Anammox bacteria in the system, due to the high presences of organic matter in the same confirmed by high concentrations of COD

Distribuição espacial das assembleias de peixes em dois trechos do alto rio Paranapanema e lagoas marginais associadas: composição e estrutura

Ichthyofaunistic studies aims to broad the knowledge of composition, abundance and distribution of species in certain areas, and when possible, to infer patterns of distribution, as well as extrinsic factors that affect these patterns in space and time. The Paranapanema River suffers the impact of the construction of hydroelectric power plants in cascade system along its main channel, changing the characteristics of lotic to lentic and semi-lentic. These changes affect the entire biocenosis and the surroundings of the reservoir and, in particular, the fish fauna. In this context, the aim of this study was to characterize the fish assemblage in two lakes and stretches of the main channel, located near the outfall of the Paranapanema River, Jurumirim reservoir area, comparing them to their composition and structure, using ecological indices as tools. Fish were caught every three months from April 2011 to January 2013, using gill nets of various mesh openings in four stretches: Environment 1 - Calha Sete Ilhas, Environment 2 - Calha Poço da Pedra, Environment 3 - Lagoa Sete Ilhas and Environment 4 - Lagoa Poço de Pedra. After the capture, the specimens were identified and biometric analysis was performed (total and standard length weight). We captured 4,006 individuals belonging to four orders and 34 species, 31 native species and three non-native species. In abundance (n) and number of species (S), there was a predominance of Characiformes (57 %) followed by Siluriformes (31%). Overall, most of the species was constant concerning the frequency of capture. The five most representative species in abundance were Schizodon intermedius, Cyphocarax modestus, Pimelodus maculatus, Hoplosternum littorale and Serrasalmus maculatus, contributing with 60% of total individuals captured. Regarding the stretches, these species present diversity (H'), evenness (E), dominance (D) and richness (d) of similar species, since the abundance was higher in ...

Evaluation of the Atibaia River water quality using Lecane bulla as a test organism

In view of the diversity of environments found in the Brazilian territory, it is understandable that the use of native species can provide more relevant information for ecotoxicological studies. The purpose of this work was to evaluate the quality of water samples from the Atibaia River in an area that is under the influence of petroleum refinery using a native test-organism and submitting the data to PCA statistical analysis. Therefore, acute toxicity assays with Lecane bulla (Rotifera) were performed in four locations of the river, as well as physical-chemical analyses. Sampling was drawn in the dry and rainy seasons. The bioassays were static and lasted 48 hours; dead organisms were quantified at the end of the tests. Toxicological differences among the samples/per location and control were compared by means of the Analysis of Variance. Physical-chemical and mortality variables were simultaneously analyzed by multivariate analysis of the principal components and the Pearson correlation coefficient. Water samples from the exit of the refinery stabilization pond (location S.1) were toxic to L. bulla in both seasons, with significant differences in relation to the control and between the seasons. The statistical treatment of data showed that mortality was strong and positively correlated with total hardness, chlorides and EC, which together with pH presented higher values in location S.1, in the dry and in the rainy seasons. Due to its sensibility to the quality of the Atibaia river water samples, the potential use of L. bulla for ecotoxicological studies as an alternative test organism could be demonstrated.
