Abstract: Abstract:The drainages of the Iguaçu River basin, as well as the main channel of the river, have peculiar characteristics resulting from geomorphological processes in this area, including the formation of the Iguaçu River Falls. This slope in the lower portion of the basin is a biogeographical barrier to many organisms. In this study was inventoried the fish fauna of streams of the lower Iguaçu River basin, evaluating possible differences in the species composition upstream and downstream of this biogeographic… Show more

“…These findings distinguish the fish fauna of headwaters of Iguaçu River basin from others similar streams of Paraná River system, with higher species richness (Araújo et al 2011, Marceniuk et al 2011, Hoffmann et al 2015, Vidotto-Magnoni et al 2015, Cetra et al 2016, Frota et al 2016a). Lower fish richness was also verified by Larentis et al (2016) to those that flows downstream it. This low richness, similar to our results, highlights the abrupt differentiations of the fish fauna between the Iguaçu drainage below falls and their upstream reaches, above the falls (Garavello et al 1997, Zawadzki et al 1999.…”

“…For example, many previous studies already demonstrated that this pattern not occur only in low Iguaçu system (Bifi et al 2006, Baumgartner et al 2012, Larentis et al 2016, Table 2. List of fish species and their respective occurrences at sampling site in eight streams of lower Iguaçu River basin.…”
