Composição da ictiofauna em função da fisiografia de um riacho costeiro de Floresta Atlântica - Brasil
Provedor de dados: 49
Autores: Guimarães,Ana Tereza Bittencourt; Menezes,Márcia Santos de; Peret,Alberto Carvalho.
Os riachos costeiros apresentam grande diversidade de peixes, apesar dos impactos a que são submetidos. O conhecimento da estrutura e da composição da ictiofauna constitui importante esforço para levantamento de parâmetros de avaliação que possam proporcionar atitudes para a conservação destes ambientes. A composição da ictiofauna relacionada a características fisiográficas de riachos costeiros do sul do Brasil constitui-se uma contribuição para a interpretação da dinâmica destes ecossistemas. Foram realizadas coletas de peixes em cinco pontos amostrais do Rio do Pinto, localizado no município de Morretes, Paraná, Brasil. As coletas foram realizadas entre os meses de maio de 2006 a novembro de 2007, utilizando a técnica de pesca elétrica, com um esforço...

A comparative analysis of biotic indices that use macroinvertebrates to assess water quality in a coastal river of Paraná state, southern Brazil
Provedor de dados: 49
Autores: Gonçalves,Fábio Bertolini; Menezes,Márcia Santos de.
Biotic indices to monitor water quality are helpful tools for evaluating the health of rivers and lakes. In Brazil water samples are mainly analyzed using physical and chemical attributes, because most biotic indices were developed in other countries and their effective application to Brazilian ecosystems requires significant research. This study compared four biotic indices commonly used to evaluate water quality via benthic macroinvertebrates in order to determine which index best reflects ecosystem health in a coastal river in Brazil's Paraná state. We also analyzed functional feeding groups. The indices studied were: 1) EPT (percent of Ephemeroptera, Plecoptera and Trichoptera); 2) BMWP' (Biological Monitoring Work Party System); 3) BMWP'-ASPT (Average...

The invertebrate's community in adjacent Alto Iguaçu's anthropic lakes of different environmental factors
Provedor de dados: 49
Autores: Krawczyk,Ana Carolina de Deus Bueno; Baldan,Lucíola Thais; Aranha,José Marcelo Rocha; Menezes,Márcia Santos de; Almeida,Cyntia Vilasboas.
Environmental differences occur between lentic and lotic communities' establishment, especially because of water time residence. Here we used a combination of field measurements and statistical analysis to evaluate the influent factors on the aquatic macroinvertebrates' composition and structure in 15 anthropogenic lakes from Alto Iguaçu's region. Macroinvertebrates were sampled from the marginal vegetation (with or without macrophytes) and sediment. Chemical parameters ranged among the anthropogenic lakes, mainly those which are connected to the Iguaçu River, beyond the presence or absence of macrophytes, interfering on the community's structure. Lake's morphometric data were measured in each lake and its relation to community was tested. The community...

Population structure and condition factor of Pseudotothyris obtusa (hypoptopomatinae) from three coastal streams in southern Brazil
Provedor de dados: 52
Autores: Takeuti,Denise de Freitas; Verani,José Roberto; Aranha,José Marcelo Rocha; Menezes,Márcia Santos de.
Population structure features and condition factor of Pseudotothyris obtusa were compared between three coastal streams in southern Brazil. Fishes were monthly collected through electric fishing and measured in the total length. Fifteen fishes from each stream were dissected to identify their sex. The structure in size, sex ratio and young/adults ratio of populations were analysed and the length-weight relationship was obtained. The condition factor (K1) and the relative condition factor (Kn) were calculated for each stream. Fishes were grouped in 11 lenght classes of 3mm. The intermediate and bigger size classes were preponderant in the "Mergulhão" and "Colônia Pereira" streams, and the smaller and intermediate ones in the "Ribeirão" stream. Females...

Age and growth of Pimelodella pappenheimi (siluriformes, pimelodidae) from an Atlantic Forest Stream in Southern Brazil
Provedor de dados: 52
Autores: Amaral,Marina Faria do; Aranha,José Marcelo Rocha; Menezes,Márcia Santos de.
Studies were performed to determine the growth curves in length and weight for Pimelodella pappenheimi in the "das Pombas" stream, a coastal stream susceptible to the flash flood phenomenon. Samples were collected from September-95 to February-97, monthly, using electric fishing. The fishes were measured in total length and weight. A total of 156 pairs of otholits were taken for ring reading. The Ford-Walford transformation allowed the use of von Bertallanffy expression. The pale ring formation was annual, and it occurred between the summer and the autumn. This species grews in length according to Lt=15.86 (1-e-0.57(t+0.1551) ) equation and in weight according to Wt= 24.23 (1-e-0.57(t+0.1551) )3.12. The increase in length was faster until the second year...
