Abstract: Abstract:In this paper is presented an analysis of possible impacts that the reduction of native vegetation, especially riparian forests, can have on the fish fauna. Three sets of primary functional aspects performed by riparian forests are discussed: transferring of solar energy to the aquatic environment, trapping nutrients and sediments that enter the rivers and transfer of organic material between the terrestrial and aquatic environments. Any modification which results in further loss of native vegetation,… Show more

“…This is verified by the presence of (i) a considerable amount of terrestrial insects (Hymenoptera and Coleoptera), seeds, and plants, which attests to the contribution of the riparian vegetation to the input of organic matter to the system (Uieda & Pinto, 2011;Casatti, 2010;Moraes et al, 2013); (ii) the presence of organisms such as Ephemeroptera, Trichoptera, Plecoptera and Decapoda (Aeglidae) that are considered to be bioindicators of environmental quality and the structural complexity of the river bed (Bispo et al, 2006;Bagatini et al, 2012;Silva et al, 2012). In these context, the results about fish's diet, indicate that the Jumelo stream may used as a possible reference environment (sensu Ferreira & Casatti, 2006) for comparisons of trophic ecology between fish communities in impacted versus nonimpacted environments.…”

“…Moreover, enhanced edge effects may occur along narrow channels, leading to degradation of riparian vegetation and favoring the colonization by invasive alien species, as well as leading to increased direct sunshine, higher temperatures, and enhanced sediment deposition or erosion, affecting the aquatic fauna (Richardson et al 2007;Casatti 2010;Tundisi & Tundisi 2010).…”

“…Among the species considered tolerant to environmental degradation, Phalloceros harpagos can be regarded as a model species, because it was associated with low fl ow and low riparian vegetation (< 6 m). The absence of native riparian vegetation typically is associated to inferior environmental quality in streams of the Atlantic Forest biome (Casatti 2010). Geophagus brasiliensis and Bryconamericus iheringii were also signifi cantly associated with lower extent of riparian vegetation.…”

“…Geophagus brasiliensis and Bryconamericus iheringii were also signifi cantly associated with lower extent of riparian vegetation. Casatti (2010) refers to the native riparian vegetation as an essential resource for maintaining the diversity of fi sh, relating the decrease in forest with species loss, faunal homogenization, and biomass reduction of these organisms.…”
