Title A name given to the resource Gradientes de diversidade nas comunidades de peixes da bacia do rio Iguatemi, Mato Grosso do Sul, Brasil Diversity gradients in fish communities of Iguatemi river basin, Mato Grosso do Sul, Brazil Creator An entity primarily responsible for making the resource Miguel Petrere Junior, Yzel Rondon Súarez Description An account of the resource Com o objetivo de verificar a importância da variação longitudinal, sazonal e a influência das características físicas e químicas da água sobre a diversidade de espécies de peixes realizamos amostragens trimestrais, entre Novembro/1999 e Agosto/2000, em três pontos amostrais no rio Jogui e oito pontos amostrais no rio Iguatemi-MS. A variação longitudinal foi mais importante que a variação sazonal na determinação da riqueza e número de indivíduos no rio Jogui, no entanto, a equitabilidade não apresentou diferença significativa sazonal ou longitudinal. No rio Jogui 78,3% da variação na riqueza de espécies, 81,6% no número de indivíduos e 41,1% na equitabilidade foram explicadas pelas características físicas e químicas da água. No rio Iguatemi nós não detectamos diferenças estatisticamente significativas longitudinais ou sazonais nos descritores analisados das comunidades nem influência significativa dos fatores ambientais.In order to verify the importance of longitudinal and seasonal variations and the effect of physical and chemical water characteristics to fish species diversity we accomplished three-month samplings, between November/1999 and August/2000, in three selected points in the Jogui River and eight points in the Iguatemi River-MS. The longitudinal variation was more important than seasonal variation in determining richness and number of individuals in the Jogui River, however, evenness did not present statistically significant differences either longitudinal or seasonal. In the Jogui River 78.3% of species richness, 81.6% of number of individuals and 41.1% of evenness variation was explained by the water chemical and physical characteristics. In the Iguatemi River we did not detect longitudinal or seasonal statistically significant differences in the analyzed community descriptors nor significant influence of environmental factors.
