RESUMO:

The streams of gallery forest and veredas are two aquatic ecosystems associated with two important phytophysiognomies of the Brazilian Cerrado Biome. These ecosystems are little explored with few studies focused on zooplankton fauna. Thus, this study aimed to answer the following questions: (i) What is the composition of zooplanktonic species of rotifers, cladocerans and copepods in gallery forest streams and veredas? (ii) Are the richness, density, diversity and composition of zooplankton species of rotifers, cladocerans and copepods different between streams of gallery forest and streams of veredas? (iii) Does environmental variables (limnological and structural) influence the richness, density and composition of zooplankton species in streams of gallery forest and streams of veredas? Data collected between the years 2016 and 2017 from 25 streams of gallery forest and 16 streams of veredas in the Upper Araguaia river basin. The total richness in gallery forest streams was 75 taxa, with 52 taxa from Rotifera, 17 taxa from Cladocera and three orders from Copepoda (Calanoida, Cyclopoida and Harpacticoida). In streams of veredas the total richness was 53 taxa, with 39 taxa of Rotifera, nine taxa of Cladocera and two orders of Copepoda (Cyclopoida and Harpaticoida). The streams of the paths have less richness, less density and diversity and different taxon composition than streams of gallery forest. Only density was significantly related with environmental variables. Conductivity was the most important variable for streams of gallery forest. Meanwhile temperature, depth, flow, stream width and percentage of grasses were more important for streams of veredas. The difference between the richness and the composition of taxa between the two ecosystems may be related to the fact that streams of paths are spatially more isolated.
