Resumo: | This study aimed at evaluating the diatom community composition found in the Canastra reservoir plankton and the temporal variation of the species from October 1997 to August 1998 and from January to December 2000, during the four seasons. The reservoir is located in Canela, in the state of Rio Grande do Sul at an altitude of 900 m in a sub-basin of the Sinos River The study was based on samplings carried out on the water sub-surface in the pelagic zone and in the litoral zone up the reservoir.The diatom community was composed of 51 specific and infraespecific taxa, including 24 genera and 19 families. About 70% of the taxa were only sporadicaly and occasionally present in different seasons of the year. Only Asterionella formosaand Urosolenia eriensis var. morsa were constant during the four seasons of the year. Among the taxa found, Achnanthes acares, Aulacoseira tenella, Brachysira inamoena, Encyonopsis subcapitata, Luticola undulata, Navicula insulsa, Nitzschia brevissima var. terricola, Pinnularia microstauron var. angusta, P. subcapitata var. subrostrata e P. viridiformis e Placoneis paraelginensis are first time reports for the State. |

O reservatório está localizado no município de Canela, no estado do Rio Grande do Sul, a cerca de 900 m de altitude, em uma sub-bacia do rio dos Sinos. O estudo baseou-se em amostragem realizada na subsuperfície da água em zona pelágica e em zona litorânea à montante do reservatório. A comunidade de diatomáceas esteve composta por 51 táxons específicos e infra-específicos, incluídos em 24 gêneros e 19 famílias. Cerca de 70% dos táxons tiveram presença esporádica e ocasional em diferentes estações do ano. Somente Asterionella formosa Hassal var. e Urosolenia eriensis H. L. (Smith) Round & Crawford var. morsa (W. West et G. S. West) Torgan foram constantes nas quatro estações do ano. Dentre os táxons encontrados, Achnanthes acares Hohn & Hellerman, Aulacoseira tenella (Nygaard) Simonsen, Brachysira inamoena Metzeltin & Lange-Bertalot, Encyonopsis subcapitata Krammer, Luticola undulata (Hilse) Mann, Navicula insulsa Metzeltin & Lange-Bertalot, Nitzschia brevissima Grunow var. terricola (Lund) Ludwig, Pinnularia microstauron (Ehrenberg) Cleve var. angusta Krammer, P. subcapitata Gregory var. subrostrata Krammer, P. viridiformis Krammer e Placoneis paraelginensis Lange-Bertalot constituem registros pioneiras para o Estado.Iheringia.
