Resumo: This study investigated the influence of hydrological phases on species composition, density and dominance of Chironomidae larvae in different types of artificial substrates. Samplings were undertaken fortnightly, between August 2004 and December 2005. Cluster analysis evidenced differences in the species composition and density of Chironomidae morphospecies among hydrological phases; according to the Kownacki dominance index, Cricotopus sp. was dominant or subdominant in all substrates and hydrological phases. During the low water phase, the greatest similarity was observed among the substrates with the same shape. In this period, the highest values of species richness and density of larvae were registered in X-shaped substrates. During the high water phase, the rise in the level of the Paraná River influenced on the reduction of mean larvae density, and only in wooden X-shaped and tube-shaped PVC substrates, whose materials best favored larvae fixing, high values of density were verified.

As coletas foram realizadas quinzenalmente, entre os meses de agosto de 2004 e dezembro de 2005. A análise de agrupamento revelou diferenças na composição e densidade das morfoespécies entre as fases hídricas e, de acordo com o índice de dominância de Kownacki, Cricotopus sp. foi dominante ou subdominante em todos os substratos e fases hídricas. Na fase de águas baixas, a maior similaridade foi observada entre os substratos de mesma forma. Nesse período, os maiores valores de riqueza e densidade das larvas foram registrados nos substratos em forma de X. Na fase de águas altas, o aumento no nível do rio Paraná influenciou na redução da densidade média das larvas e somente nos substratos de madeira em forma de X e PVC em forma de tubo, cujos materiais favoreceram a melhor fixação das larvas, foram registrados maiores valores de densidade.Universidade Estadual De Maringá2010-05-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/mswordhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/538710.4025/actascibiolsci.v32i2.5387Acta Scientiarum.
