Resumo: The present study aimed to describe the fl oristic composition and the changes of diatom associations in the Itajai-Mirim River along its altitudinal gradient and with different land uses. The study was based on quarterly sampling of epilithon at six stations between 2004 and 2006. A total of 79 taxa, distributed in 24 families and 36 genera, were identifi ed. The families with the highest species richness were Naviculaceae, Gomphonemataceae, Cymbellaceae, and Bacillariaceae. These families along with the Achnanthidiaceae had the greatest relative abundances. Changes in diatom associations along the altitudinal gradient of the Itajaí-Mirim River were more evident in lowland areas, with anthropogenic activities such as sand extraction and discharge of domestic and industrial effl uents. The important species, as provided by the Important Species Index, refl ected the environmental conditions.

O estudo baseou-se em coletas trimestrais do epilíton, em seis pontos, entre 2004 e 2006. Um total de 79 táxons foram identifi cados, distribuídos entre 24 famílias e 36 gêneros. As famílias mais representativas em relação à riqueza específi ca foram Naviculaceae, Gomphonematacea, Cymbellaceae, e Bacillariaceae, que também foram as mais abundantes, juntamente com Achnanthidiaceae. Mudanças nas associações de diatomáceas ao longo do gradiente altitudinal do rio Itajaí-Mirim foram mais evidentes nas áreas de menor altitude com atividades antropogênicas, como extração de areia e descarga de efl uentes domésticos e industriais.
