Resumo: Aiming to describe the patterns of the fish assemblages organization in streams of the Iguatemi River basin we sampled streams with seine nets and sieves from November/1999 to August/2000. We collected 567 individuals distributed in 24 species. We detected statistically significant influence of the streams characteristics upon species diversity. The species composition was hardly explained by the physical and chemical characteristics of the streams. Then we detected significant influence of the fish ecomorphology in the species occurrence (Mantel r = -0,34; P = 0,04), but not in the distribution of its abundance (Mantel r = -0,21; P = 0,07). We verified through the species co-occurrence index (C-score) that its composition in the studied streams is stochastic

Coletamos 567 indivíduos distribuídos em 24 espécies. Constatamos influência significativa das características dos riachos sobre a diversidade de espécies. A composição de espécies foi pouco explicada pelas características dos riachos. Verificamos influência significativa da morfologia na distribuição em ocorrência das espécies (Mantel r = -0,34; P = 0,04), mas não na distribuição em sua abundância (Mantel r = -0,21; P = 0,07). Comprovamos através do índice de co-ocorrência (C-score) das espécies que sua composição nos riachos estudados é estocásticaUniversidade Estadual De Maringá2008-03-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/135010.4025/actascibiolsci.v27i2.1350Acta Scientiarum.
