Resumo: | Spatial and temporal variation was analyzed in the composition, diversity, and abundance of cyclopoid copepods associated with Eichhornia azurea (Swartz) Kunth in two lotic environments of the Upper Paraná river basin. Sixteen cyclopoid taxa were identified. There were no differences in the composition of copepod species between environments or hydrological phases. Cyclopoids were generally more abundant during the low water phase. The most abundant species in both environments were Macrocyclops albidus albidus (Jurine) and Microcyclops finitimus Dussart. Densities and some measurements of species richness were in general higher in the Ivinheima River, which has many associated floodplain lakes. This fact suggests the importance of associated lentic environments for patterns of abundance and species richness found in lotic environments. Low values for β diversity of the cyclopoid assemblage in both environments seem to indicate that the littoral region has low temporal heterogeneity |

Foram identificados dezesseis táxons de ciclopóides. Não foram constatadas diferenças na composição de espécies entre os ambientes ou fases hidrológicas. Os ciclopóides foram, em geral, mais abundantes durante a fase de águas baixas. As espécies mais abundantes nos dois ambientes foram Macrocyclops albidus albidus (Jurine) e Microcyclops finitimus Dussart. As densidades e algumas medidas de riqueza de espécies foram, em geral, maiores no rio Ivinheima, o qual apresenta muitas lagoas de várzea associadas. Esse fato sugere a importância de ambientes lênticos para os padrões de abundância e riqueza de espécies encontrados em ambientes lóticos. Os baixos valores de diversidade β para a assembléia de ciclopóides nos dois ambientes estudados sugerem que a região litorânea têm uma baixa heterogeneidade temporalUniversidade Estadual De Maringá2008-05-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/268810.4025/actascibiolsci.v23i0.2688Acta Scientiarum.
