Title A name given to the resource Periphytic algal community in artificial and natural substratum in a tributary of the Rosana reservoir (Corvo Stream, Paraná State, Brazil) = Comunidade de algas perifíticas em substrato artificial e natural em um tributário do reservatório de Rosana (Ribeirão do Corvo, Estado do Paraná, Brasil) Creator An entity primarily responsible for making the resource Sirlene Aparecida Felisberto, Liliana Rodrigues Description An account of the resource Periphytic algal community in artificial and natural substratum in a tributary of the Rosana reservoir (Corvo Stream, Paraná State, Brazil). This study evaluated the heterogeneity in periphytic algal community, under the influence of time colonization on artificial substratum. We also examined which abiotic variables most influenced the community in natural and artificial substratum. Egeria najas Planchon was used as natural substratum, and a plastic plant, asartificial. This experiment was carried out in a lateral arm from Rosana Reservoir, formed by Corvo Stream (Paranapanema river basin), in the period from November 21st to December 12nd, 2003, characterized as a warm and rainy period. Changes in species composition were assessed using the similarity indices. 495 taxa were registered in the phycoperiphytic community, distributed in 133 genera and 11 classes. Zygnemaphyceae, Bacillariophyceae, Chlorophyceae and Cyanophyceae presented higher species number, in both substrata. Staurodesmus, Closterium, Staurastrum and Cosmarium (Desmidiales); Gomphonema and Eunotia (Pennales); Characium, Scenedesmus and Desmodesmus (Chlorococcales); Anabaena and Aphanocapsa (Nostocales and Chroococcales, respectively) were the most species-rich genera. The epiphytic community reached the highest species richness in the 15th successional day. Regardless the substratum type, the number of species was probably related to the high concentrations of nutrients (phosphorus and nitrogen).Este trabalho objetivou analisar a composição da comunidade de algas perifíticas sob influência do tempo de colonização em substrato artificial. Ainda procurou responder quais variáveis abióticas mais influenciaram na comunidade em substrato artificial e natural. Utilizou-se Egeria najas Planchon como substrato natural e planta de plástico semelhante à Egeria como artificial. O experimento foi realizado no rio do Corvo, tributário do reservatório de Rosana (bacia do Paranapanema). As amostragens foram realizadas de 21 de novembro a 12 de dezembro de 2003, quando o clima é caracterizado como quente e chuvoso. As alterações na composição específica do ficoperifíton foram analisadas utilizando-se o índice de similaridade. A comunidade de algas perifíticas compreendeu 495 táxons, distribuídos em 133 gêneros e 11 classes. Zygnemaphyceae,Bacillariophyceae, Chlorophyceae e Cyanophyceae apresentaram maior número de espécies, em ambos os substratos. Staurodesmus, Closterium, Staurastrum e Cosmarium (Desmidiales); Gomphonema e Eunotia (Pennales); Characium, Scenedesmus e Desmodesmus (Chlorococcales);Anabaena e Aphanocapsa (Nostocales e Chroococcales, respectivamente) foram os gêneros mais representativos. A comunidade perifítica do substrato artificial atingiu maior número de espécies no 15º dia sucessional. O número de espécies independentemente do tipo de substrato foi relacionado à maior disponibilidade de nutrientes (fósforo e nitrogênio).
