Abstract: From December 2003 to September 2004, benthic macroinvertebrates (BM), fishes, water and sediment were collected quarterly at six stations in two streams of the upper São Francisco River basin, south-eastern Brazil. We evaluated the ecological conditions, habitat diversity, water quality, composition and structure of BM communities, as well as the food habits of the local fish fauna. By applying a protocol for rapid characterization of ecological conditions and habitat diversity, three of the sampled localitie… Show more

“…Obviously, a more comprehensive inventory of the ichthyofauna of the streams surveyed here and the rest of the Japaratuba basin would require the collection of a much more systematic sample, including a much longer period, covering seasonal variations in climate, and the use of additional capture techniques, such as seine nets and electric fishing (Castro et al, 2004 Nine benthic invertebrate taxa were identified in the stomach contents of these specimens: Ostracoda, Hidracarina, Ceratopogonidae, Chironomidae, Simuliidae, Tipulidae, Libellulidae, Calamoceratidae, and Pyralidae. The taxonomic richness of these organisms was relatively low in comparison with the results of other studies based on a similar approach (Callisto et al, 2002b;Tupinambás et al, 2007). For more reliable and conclusive data on these parameters, a much larger sample of fish would be required, in particular of benthophagous species, which were not collected in the present study and would increase the inventory of aquatic insects (Fagundes et al, 2008).…”

“…In addition, fish may often be relatively rare in headwater streams, such as those studied here (Tupinambás et al, 2007).

“…However, streams in fully preserved areas to assess the distribution of biological communities are increasingly scarce (Tupinambás et al, 2007). Thus, assess their current state and estimating how environmental characteristics may affect their future condition are vital measures for making decisions that maximize protection of biodiversity and the services provided by the ecosystem.…”

“…In the state of Minas Gerais, studies in freshwater ecosystems have been carried out regarding various groups composing the community of benthic macroinvertebrates in preserved areas, such as the works of Callisto et al (2001), Goulart & Callisto (2005), Tupinambás et al (2007) and Rosa et al (2011). Nevertheless, none until now have focused on the Oligochaeta.…”
