Resumo: The influence of spatial, temporal and environmental factors on fish species diversity in headwater streams in Paraguay and Paraná basins, Brazil was examined. A total of 4,605 individuals were sampled, distributed in 60 species. The sampled streams in Paraná basin presented a larger total species richness (42) than Paraguay streams (40). However the estimated richness was larger in Paraguay basin (53) than Paraná streams (50). The streams of Paraná basin had a greater mean species richness and evenness, while more individuals per sample were found in the Paraguay basin. Difference between the sub-basins were found in the Paraguay basin, while for the basin of Paraná, richness and evenness vary significantly between the sub-basins, but the number of individuals varied seasonally. The most important environmental factors to species diversity and abundance were altitude, water temperature, stream width and stream depth for both the basins.

Os riachos da bacia do rio Paraná apresentaram maior riqueza total de espécies (42) que os riachos da bacia do rio Paraguai (40), no entanto, a riqueza estimada foi maior na bacia do rio Paraguai (53) que nos da bacia do rio Paraná (50). Os riachos da bacia do rio Paraná apresentaram maiores valores médios de riqueza e equitabilidade, contudo, maiores valores médios de número de indivíduos foram obtidos na bacia do rio Paraguai. Encontramos diferenças significativas entre as sub-bacias do rio Paraguai assim como do rio Paraná para a riqueza de espécies e equitabilidade, contudo, nesta última o número de indivíduos variou apenas sazonalmente. As variáveis ambientais mais importantes na determinação da diversidade e abundancia das espécies foram altitude, temperatura da água, largura e profundidade dos riachos para as duas bacias.Brazilian Archives of Biology and Technology2019-05-28T16:49:17Z2019-05-28T16:49:17Z2007-11info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf16784324http://dx.doi.org/10.1590/S1516-89132007000700014http://www.locus.ufv.br/handle/123456789/25569engv. 50, n. 06, p. 1033- 1042, nov. 2007Felipe, Thiago Rota AlvesSúarez, Yzel RondonValério, Sabrina BigatãoTondado, Karina KeylaFlorentino, Alexandro CezarXimenes, Lidiani Queli LubasLourenço, Luzia da Silvainfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T07:45:09Zoai:locus.ufv.br:123456789/25569Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T07:45:09LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
