| The structure and composition of a fish community in a tributary stream of the Aquidauana River, located in the plateau region of the Paraguay River basin, central west Brazil are described, with special attention to the differential effects of the phytophysiognomies of the Cerrado (a tropical savanna), which are predominant in riparian zones all along their longitudinal gradient. A total of 1,166 individuals belonging to 44 species were captured. Similarity analyses of composition and abundance showed two groups: upstream reaches (R1 and R2) and downstream reaches (R3, R4 and R5), which presented 85.8% of the average dissimilarity. Although physical habitat and physicochemical descriptors varied along the longitudinal gradient of the Correntes stream,... |

| Abstract The objective of this study was to provide a comprehensive list of the fish fauna of headwater streams of the Miranda River in the Upper Paraguay River Basin. Our primary data set was constructed from sampling of fish using a rectangular sieve, trawl, and gill nets from 2004 to 2015. Our secondary data were derived from published reports conducted in the Miranda River Basin, in addition to taxonomic and distribution data from other studies conducted in the basin. All data were compiled, which in the end encompassed a period from 1999 to 2015. The datasets yielded a total of 143 species, 104 from the primary data (72.7%) and 39 from the secondary data (27.3%). Species were distributed among seven orders and 30 families were found in the Miranda... |
