Resumo: Along its course, the Paranapanema River presents some hydroelectric dams. During the year 2001, seven of these (Chavantes, Salto Grande, Canoas II and I, Capivara, Taquaraçu and Rosana) had their periphytic community studied. Samples of periphyton in natural substratum of the epiphyton type were collected from the river banks during the dry and the rainy seasons. Overall, the periphytic biomass in reservoirs of the Paranapanema River was characterized according to the rain regime of the area with higher and irregular values in the rainy period. The periphytic community demonstrated higher values of biomass, composition and abundance in the reservoirs located in middle Paranapanema, especially in Salto Grande and Canoas I. The Rosana and the Capivara Reservoirs presented higher values of algal density, chlorophyll a and species richness. The structure of the phycoperiphytic community was controlled by several factors, especially oscillation in precipitation, secchi depth, depth, retention time, temperature and water nutrients

Em 2001, sete desses foram estudados quanto à comunidade perifítica: Chavantes, Salto Grande, Canoas II e I, Capivara, Taquaraçu e Rosana. As coletas do perifíton (epifíton) foram realizadas em dois períodos e sempre na região litorânea. A biomassa perifítica nos reservatórios do rio Paranapanema foi caracterizada pelo regime pluviométrico da região, sendo os valores mais elevados e irregulares no período chuvoso. Foi observada maior semelhança entre a biomassa, a composição e a abundância nos reservatórios situados no médio Paranapanema, especialmente em Salto Grande e Canoas I. Os reservatórios de Rosana e de Capivara apresentaram uma maior riqueza de táxons, densidade algal e maiores valores de clorofila a. Sugere-se que a estrutura da comunidade ficoperifítica foi controlada por vários fatores, como precipitação, transparência, profundidade, tempo de retenção, temperatura e nutrientes da águaUniversidade Estadual De Maringá2008-03-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/133310.4025/actascibiolsci.v27i3.1333Acta Scientiarum.
