“…The release of fish by aquarium hobbyists, however, has been responsible for the introduction of P. ambrosettii , Pterygoplichthys disjunctivus (Weber 1991), Pterygoplichthys multiradiatus (Hancock 1828) and Pterygoplichthys pardalis (Castelneu 1855) in the U.S.A. (Nico & Martin, ; Hoover et al, ; Nico et al, , ), Mexico (Espinosa Perez & Ramírez, ), South Africa (Jones et al, ), Philippines (Chavez et al, ), China (He, ) and India (Sinha et al, ). The common use of P. ambrosettii in the Brazilian aquarium trade and its ability to ascend fish ladders have probably contributed its rapid geographic spread and establishment in the upper Paraná River basin (Casimiro et al, ).…”

This study describes the invasion of the upper Paraná River basin by Pterygoplichthys ambrosettii based on a literature review and field samples. Pterygoplichthys ambrosettii has been reported in 42 localities throughout the upper Paraná River basin, including the Tietê, Paranapanema, Paraná, Grande and Aguapeí rivers. The ascent of P. ambrosettii after the inundation of the Sete Quedas Falls on the Paraná River and the release of individuals by aquarium hobbyists were the primary drivers of this invasion.

“…migratory fish) in older reservoirs than newly formed impoundments (Agostinho et al., ; Loures & Pompeu, ). In addition, the creation of reservoirs favours non‐native species establishment, becoming an additional threat to native freshwater fish (Bunn & Arthington, ; Casimiro, Garcia, Costa, Britton, & Orsi, ; Johnson, Olden, & Vander Zanden, ; Toussaint, Beauchard, Oberdorff, Brosse, & Villéger, ). Generally in the long‐term, fish assemblages in reservoirs show dominance of small‐bodied species, with generalist feeding habits and sedentary lifestyles (Agostinho et al., ; Hoeinghaus et al., ).…”

Temporal changes in fish diversity in lotic and lentic environments along a reservoir cascade

Long‐term modifications in hydrological conditions due to river damming result in varied effects on fish diversity, which can be stronger in a reservoir cascade. Therefore, we assessed changes in fish diversity over a 28‐year period, in a series of reservoirs along the Araguari River Basin, a Neotropical drainage in Brazil, in both lentic environments (reservoirs) and the lotic stretches between them. We used linear mixed models to assess long‐term changes in fish diversity. Diversity was measured as α diversity (fish species richness) and β diversity (Jaccard's and Raup–Crick's dissimilarity index). Beta diversity was then partitioned into turnover (species replacement) and nestedness (species loss). To understand fish species replacement along the cascade, we modelled turnover with four covariates: age, richness of native and non‐native fish species, and longitudinal position of sampling site along the cascade. The reduction of total richness and the increase in non‐native richness were related to reservoir age. These effects were similar in both lotic and lentic environments, with no significant difference between them. We also observed a decrease in native fish richness over time, with a slight tendency for lentic environments to lose more species than lotic environments. Dissimilarity in fish assemblage increased over time and β Raup–Crick results corroborated those derived from β Jaccard, yielding similar significant temporal trends. Changes in fish species composition occurred predominantly due to turnover, compared to nestedness. We observed a greater species loss in reservoirs, suggesting that the transformation from a lotic environment into a lentic had greater impact on fish assemblages than the flow regulation of the lotic stretches downstream of the dams. Our results suggest that species replacement can be explained mainly by the increase of non‐native fish richness, followed by the longitudinal position along the cascade in an upstream–downstream direction, and reservoir age. This study reveals that, even after 2 decades of monitoring, we still observe important changes in fish assemblages, demonstrating the importance of long‐term monitoring to assess biodiversity. Our findings reinforce the importance of long‐term fish monitoring schemes for the investigation of the effects of non‐native fish species on native fish assemblages.

“…Likely, the most widely distributed anthropogenic alteration of freshwater ecosystems is dam construction, which cause fragmentation within a basin, modify natural flow regimes and disrupt sediment transportation (Osmundson et al 2002;Leprieur et al 2008;Ren€ of€ alt et al 2010, Liu et al 2012. In addition, reservoirs themselves have been reported to favor the dispersal and establishment of introduced species (Johnson et al 2008;Sk ora et al 2015;Liew et al 2016;Casimiro et al 2017). And variables related to reservoir morphology such as reservoir capacity have been found to be inversely correlated to biotic integrity (Moyle and Randall 1998).…”

The introduction of exotic species is a key global threat to biodiversity. Beyond an increased risk of native species extinction, there exists a loss of biodiversity distinctiveness. Nevertheless, quantitative information on biotic homogenization at the taxonomic level in relation to basin features is rare. We used freshwater fish distribution data in Spain at three different time periods (1952, 1995, and 2007) to assess the species introduction process and the temporal dynamics of taxonomic homogenization among river basins in relation to basin size, native species richness and dam construction variables. The degree of alteration of original faunas by species introduction has increased through time, especially in native richer species, which suggest that the number of non-native and native species covariate with environmental heterogeneity. On the other hand, neither basin size nor habitat modification by dam construction seems to explain the number of introduced species. Our results indicate that the taxonomic homogenization of Spanish fish fauna is a temporally and spatially dynamic process; initial local increases in b-diversity through species introduction could be blurred because of scaling to regional and national levels or by the continuous expansion of a reduced number of exotic species.
