“…This pattern of low species richness, associated with high endemism, has also characterized the ichthyofauna of other low-order streams in Iguaçu River basin (Ingenito et al 2004, Bifi et al 2006, Abilhoa et al 2008. 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.…”

“…Characidae with a great number of smaller sized and generalists foraging species (sensu Castro 1999, Abelha et al 2001, normally have co-dominated with armored dwellers Loricariidae (Castro et al 2003, Araújo et al 2011, Hoffmann et al 2015, Vidotto-Magnoni et al 2015, or with catfishes Heptapteridae (Pereira et al 2014), and eventually with Cichlidae (Gubiani et al 2010), when non-native tilapias are present. However, similar to found herein, Trichomycteridae have been representative in low Iguaçu streams (Frota et al 2016b, Larentis et al 2016, probably by morphological adaptations of its species to dwelling in varied streams (Casatti 2003).…”

“…While others similar large tributaries from upper Paraná River system (e.g., Paranapanema, Tietê, Grande) include more than 150 fish species (Langeani et al 2007, Duke Energy 2008, the inventories along Iguaçu River basin have not exceeded much more than one hundred species, added those introduced (Baumgartner et al 2012). Its low species richness is more evident in smaller spatial scales, where local fish assemblages of streams have presented between six to 12 species (Vitule & Abilhoa 2003, Bifi et al 2006, Abilhoa et al 2008, Neves et al 2015, Larentis et al 2016, while others streams with similar magnitude from Paraná system, between 13 to 41 species (Castro et al 2003, Delariva & Silva 2013, Cetra et al 2012, Vidotto-Magnoni et al 2015.…”

Fish fauna in forested and rural streams from an ecoregion of high endemism, lower Iguaçu River basin, Brazil

et al. 2018

The fish fauna of eight streams with different land uses of their watersheds (forested and rural areas) in the lower Iguaçu River basin was inventoried, in order to evaluate the composition and species richness. The fishes were sampled quarterly from May 2015 to February 2016, using the electrofishing technique. In total, 4,239 individuals were captured, belonging to six orders, 11 families and 26 species. The orders Siluriformes and Characiformes, and the families Characidae and Trichomycteridae were the most specious. Of the total species sampled, 65% were endemic to the Iguaçu River basin, four are not described and four are non-native. As expected to the Iguaçu River basin, the inventoried fauna revealed low richness and high endemism, however was highly nested within the species composition reported for main channel of Iguaçu River and their larger tributaries. The species recorded here corresponded to a subset of 24.5% of the 106 species documented for the basin. The streams presented different faunas, with only two species (Astyanax bifasciatus and Trichomycterus stawiarski) common to both forested and rural streams. In addition, higher species richness was recorded in streams inserted in conservation units. The presence of non-native species was more frequent in rural streams. These results highlight the importance of the preservation of forested areas in the watersheds of lower Iguaçu, which presents a peculiar fish fauna, along with several threats to biodiversity such as habitat loss by intensive agriculture use.

“…The Paranapanema River -one of the most important tributaries of the left margin of the Paraná River (Maack 2002, Duke Energy 2008 -hosts a significant part of this diversity, as evidenced by several fish inventories and ecological studies performed on its main course (Carvalho et al 1998, Pelicice et al 2005, Britto & Carvalho 2006, Orsi 2010, Orsi & Britton 2014, Pelicice et al 2018, tributaries, and sub-tributaries (Castro et al 2003, Cerqueira & Smith 2015, Vidotto-Magnoni et al 2015, Rosa et al 2016. Past works suggest that species compilations from the Paranapanema River alone vary from 155 (Duke Energy 2008) to 161 (Pelicice et al 2018).…”

Fish fauna from the Paranapanema River basin, Brazil

The Paranapanema River is an important, extensively explored tributary of the Upper Paraná River basin. The fish fauna of the Paranapanema River has been investigated since the 1990s; however, no study has characterized the richness of fish species throughout the basin, including the main channel of the river, marginal lagoons, its tributaries, and sub-tributaries. Thus, we performed a review with 90 independent studies conducted at the upper, middle, and lower sections of the basin. We recorded 225 species, of which 165 were native, and 60 were non-native. We found that 77% of the species within the basin are composed by Siluriformes and Characiformes. Cichliformes had a significant number of non-native species established in impoundment sections of the basin. Incidence-Based Estimators (Bootstrap and Chao 2) demonstrated that the richness of native species is still underestimated. Some native (e.g., Hypostomus ancistroides) and non-native species (e.g., Plagioscion squamosissimus) are widely distributed in the basin, while others had a more restricted distribution. Among the registered species, the family Bryconidae had the highest number of representatives with threatened conservation status. In addition, we observed that the Capivara Reservoir and its tributaries were the most sampled regions, with the majority of studies performed in the Lower Paranapanema basin. The species richness recorded in large tributaries, such as Tibagi, Cinzas, Congonhas, and Pirapó rivers is critical for maintaining the fish fauna in the Paranapanema River. Our contribution may be used to support management actions and conservation strategies, as well as to indicate regions in the basin that need to be better inventoried.

“…Ichthyological surveys, also referred to in scientific literature as inventories (e.g., Giongo et al 2011;Vidotto-Magnoni et al 2015), are performed in order to assess the biodiversity of a stream, river or lake (Silveira et al 2010). Consequently, these studies may result in new discoveries (e.g., undescribed species) and can be implemented as the basis for conservation actions (e.g., Castro et al 2004, Serra et al 2007, Raiol et al 2012, Ohara & Loeb 2016, Silva-Oliveira et al 2016, Melo et al 2016, Ferreira et al 2017.…”

The Ribeirão Frutal basin is located within the upper Rio Paraná system, in the Frutal municipality, Minas Gerais State, Southeastern Brazil. Until now, there was no complete ichthyological survey published for this small basin. Therefore, here we provided a list of fish species from the Ribeirão Frutal and some of its tributaries. We found 31 species of fishes representing five orders and ten families. We identify a likely undescribed and five non-native species in the Frutal basin. Lastly, we recommend new surveys of fishes in small hydrographic basins within upper Rio Paraná system. Keywords: Ichthyology, inventory, Neotropical region, Rio Grande, survey. Ictiofauna do Ribeirão Frutal e afluentes, bacia do alto Rio Paraná, Minas Gerais, Sudeste do BrasilResumo: A bacia do Ribeirão Frutal está localizada no sistema do alto Rio Paraná, no município de Frutal, Estado de Minas Gerais, Sudeste do Brasil. Até o momento, não existe publicação de um levantamento ictiológico completo para essa bacia. Portanto, aqui fornecemos uma lista das species de peixes do Ribeirão Frutal e alguns de seus tributários. Nós encontramos 31 espécies de peixes representando cinco ordens e 10 famílias. Identificamos uma provável espécie não descrita e cinco não nativas na bacia do Frutal. Por fim, recomendamos novos levantamentos de peixes em pequenas bacias hidrograficas do sistema do alto Rio Paraná. Palavras-chave: Ictiologia, inventário, levantamento, região Neotropical, Rio Grande.
