Resumo: In order to evaluate spatial-temporal distribution of periphytic cyanobacterial community, as well as the influence of abiotic factors on these organisms, samples were collected in two reservoirs: Segredo and Iraí, located within the Iguaçu river basin, State of Paraná. Samplings were collected in summer (April) and winter (September), 2002, in upper, intermediary and lower regions. A total of 66 cyanobacterial species were registered, with fifty species occurring in Iraí Reservoir and thirty-eight in Segredo Reservoir. Iraí showed higher values of cyanobacteria density (25 to 101 x ind 103 cm-2) when compared with Segredo (1 to 14 x ind 103 cm-2). We believe that cyanobacteria composition and density resulted from several factors, with preponderance of the effects of abiotic variables differences (nitrogen, phosphorus and temperature) along the longitudinal axis and along the different seasons, as well as the morphometric and hydrodynamic effects.

As coletas foram realizadas no verão (abril) e no inverno (setembro) de 2002, nas regiões superior, intermediária e inferior dos reservatórios. Foram inventariadas 66 espécies de cianobactérias, sendo que Iraí apresentou 50 táxons e Segredo 38. O reservatório de Iraí apresentou densidade de cianobactérias (25 a 101 x ind. 103 cm-2) maior do que aquelas observadas para Segredo (1 a 14 x ind. 103 cm-2). Acredita-se que a composição e a densidade cianobactérias foram resultados de uma combinação de fatores, em que as diferenças nas variáveis abióticas (nitrogênio, fósforo e temperatura) ao longo do eixo rio-barragem e nas diferentes estações, a morfometria e a hidrodinâmica foram consideradas preponderantes.Universidade Estadual De Maringá2006-11-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/16510.4025/actascibiolsci.v28i4.165Acta Scientiarum.
