Resumo: The floodplain of the upper Paraná river is characterized by the great diversity of aquatic organisms, and the larvae of Chironomidae are distinguished for their high density. Starting from the hypothesis that abiotic variables influence Chironomidae larvae composition, density and dominance in different environments and sampled periods, this study aimed to characterize the Baía river, secondary channel, floodplain lakes (connected and non-connected) of the Paraná river floodplain, according to attributes of Chironomidae assemblage, and identify possible gradients of temporal and spatial distribution of the larvae, relating them with abiotic variables. The collections were carried out from March 2003 to December 2005. Samples were collected in three points (margins and center), using a modified Petersen grab. CCA showed the larvae were influenced mainly by sediment particle size. Curutuba channel, due to the presence of pebbles, differed from other sites such as the Baía river and floodplain lakes, where fine particles predominated. It was concluded that particle size composition, percentage of organic matter and hydrodynamic of each environment were the main variables that influenced the spatial distribution of Chironomidae larvae.

A partir da hipótese de que as variáveis abióticas influenciam a composição, densidade e dominância das larvas de Chironomidae em diferentes ambientes e períodos amostrados, este trabalho objetivou: caracterizar o rio Baía, canal secundário, lagoa não-conectada (Fechada) e lagoa conectada (Guaraná) da planície de inundação do alto rio Paraná, de acordo com os atributos da assembléia de Chironomidae e identificar possíveis gradientes de distribuição espacial e temporal das larvas, relacionando-as com algumas variáveis abióticas. As coletas foram realizadas no período de março de 2003 a dezembro de 2005, em três pontos distintos (margens e centro), com o auxílio de um pegador tipo Petersen modificado. A Análise de Correspondência Canônica mostrou que as larvas foram influenciadas principalmente pela textura granulométrica do sedimento. O canal Curutuba, pela presença de seixos, diferenciou-se das demais estações de coleta como rio Baía e as lagoas de inundação onde predominaram as partículas mais finas. Pode-se concluir que a composição granulométrica, a porcentagem de matéria orgânica presente no sedimento e a hidrodinâmica de cada ambiente foram os principais fatores que influenciaram a distribuição espacial das larvas de Chironomidae.Universidade Estadual De Maringá2011-05-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/538610.4025/actascibiolsci.v33i4.5386Acta Scientiarum.
