Title A name given to the resource Temporal changes in fish species composition of headwater streams of the upper Paraguay and Paraná basins, Brazil = Alteração temporal na composição de espécies de peixes em riachos de cabeceira das bacias do alto Paraguai e Paraná, Brasil Creator An entity primarily responsible for making the resource Yzel Rondon Súarez, Karina Keyla Tondato Description An account of the resource This study was carried out in headwater streams in the Paraguay and Paraná river basins, with bi-monthly samples from January to November 2004, aiming to quantify the influence of environmental factors on the temporal rate of turnover in species composition of the fish communities. The environmental variables explained 73.5% of the variation in beta diversity and 52.5% of the variation in mean dissimilarity. Altitude was the only environmental descriptor that significantly explained the variation in beta diversity and mean dissimilarity in both basins.O presente estudo foi realizado em riachos de cabeceira nas bacias dos rios Paraguai e Paraná, por amostragens bimestrais de janeiro a novembro de 2004, com o objetivo de se quantificar a influência dos fatores ambientais sobre a taxa de alteração temporal na composição de espécies nas comunidades de peixes. As variáveis ambientais utilizadas explicaram 73,5% da variação na taxa de alteração na composição de espécies, utilizando a diversidade beta e 52,5% da variação na taxa de alteração pelo coeficiente de Jaccard. A altitude dos locais amostrados foi o único preditor significativo da taxa de alteração temporal na composição de espécies para ambas as bacias.
