Abstract: In stream environments habitat structure and limnological factors interact regulating patterns of energy and material transfer and affecting fish communities. In the coastal basins of Southeastern Brazil, limnological and structural characteristics differ between clear and blackwaters streams. The former have a diversity of substrate types, higher water velocities, and lower water conductivity, while the latter have sandy substrate, tea-colored and acidic waters, and low water velocities. In this study, we ver… Show more

“…Furthermore, this ensured only direct dispersal interactions between sites, with no confounding in the data through multiple dispersal events, which occurs in the rainy season (Cottenie 2005). This sampling protocol has been efficiently used to collect fishes inhabiting small (width ≈ 5 m) tropical headwater streams (Gonçalves and Braga 2012;Ferreira et al 2014).…”

“…In the Brazilian Atlantic Forest, it is well known that fish assemblages are influenced by local habitat structure (Abilhoa et al, ; Mazzoni, Fenerich‐Verani, Caramaschi, & Iglesias‐Rios, ; Terra, Hughes, & Araújo, ) such as depth, water velocity, and substrate (Ferreira, Silva, Gonçalves, & Petrere, ; Gonçalves & Braga, ). The importance of spatial structure in the organization of fish assemblages is revealed by species zonation along an upstream–downstream gradient of environmental heterogeneity (Balon & Stewart, ; Ferreira & Petrere, ; Hynes, ; Mazzoni & Lobón‐Cerviá, ; Rahel & Hubert, ).…”

“…The contribution of local predictors emphasises the importance of maintaining habitat characteristics similar to least impacted conditions for the conservation of stream fish assemblages in the Cerrado (Casatti, Ferreira & Carvalho, ; Ferreira, Silva, Gonçalves & Petrere, ; Walrath, Dauwalter & Reinke, ). Coarse substrate, flow velocity and leaf litter accumulations were particularly important instream characteristics related to fish assemblage composition in the final RDA model.…”

“…The contribution of local predictors emphasises the importance of maintaining habitat characteristics similar to least impacted conditions for the conservation of stream fish assemblages in the Cerrado (Casatti, Ferreira & Carvalho, 2009;Ferreira, Silva, Gonçalves & Petrere, 2014;Walrath, Dauwalter & Reinke, 2016 (Carvalho, Fidelis, Arruda, Galuch & Zuanon, 2013;Casatti et al, 2009). On the other hand, impaired streams without riparian vegetation are more susceptible to siltation due to sediment input from adjacent areas, causing homogenisation of stream bottom habitats (Bojsen & Barriga, 2002;Dauwalter, Wenger & Gardner, 2014;Growns, Gehrke, Astles & Pol Lard, 2003).…”
