Resumo: | In order to quantify the importance of some physiographic characteristics of headwaters streams of Ivinhema basin on occurrence of four Characidae species, bimonthly samples in 10 streams using a rectangular sieve, with standardized sampling effort were collected. The influence of environmental descriptors on species occurrence was quantified using a logistic regression model. It was observed that the water velocity was the main limiting factor to occurrence of Serrapinnus notomelas, Hemigrammus marginatus and Moenkhausia sanctaefilomenae while stream depth was the main determinant of Bryconamericus stramineus occurrence. Thus, the first three species are found mainly in sites with less water velocity, while B. stramineus is found mainly in sites with less depth and higher water velocity, suggesting that physiographic habitat characteristics can be important determinants of species colonization and persistence. |

A influência das variáveis ambientais sobre a ocorrência das espécies de peixes foi quantificada utilizando-se do modelo da análise de regressão logística. Constatou-se que a velocidade da correnteza foi o principal fator limitante da ocorrência de Serrapinnus notomelas, Hemigrammus marginatus e Moenkhausia sanctaefilomenae, enquanto a profundidade dos riachos foi o principal determinante da ocorrência de Bryconamericus stramineus. Assim, as primeiras espécies ocorrem predominantemente em locais com baixa velocidade da correnteza, enquanto B. stramineus ocorre principalmente em locais com pouca profundidade e com elevada velocidade da correnteza, sugerindo que as características fisiográficas dos habitat sejam importantes determinantes da colonização e persistência das espécies.
