“…We agree that it is non-native to the Guareí River basin. Poecilia reticulata is widespread in southeastern Brazil (Dias et al 2020), including the Upper Paraná basin (e.g., Araújo et al 2011;Cunico et al 2019;Pagotto et al 2012;Alves et al 2016). In our study, this fish was captured in sites with urban impact, within the city of Angatuba.…”

The Guareí River is a tributary of the Paranapanema River (Brazil), located in the upper portion of the Jurumirim Reservoir. Fish fauna studies in this watershed began in the 2000s, but they were restricted to a few waterbodies. This work conducted a broad survey of the fish fauna in tributary streams and the main channel of the Guareí River. Sampling occurred between February 2017 and November 2018 at 36 sites and using different collection methods. We captured 2,169 specimens belonging to 50 species, 16 families and 6 orders. The species accumulation curve tended to stabilize but indicated that species richness is underestimated. Almost all species are native (46); only three were non-native (Hyphessobrycon eques, Oreochromis niloticus and Poecilia reticulata) and one was undefined (Gymnotus pantanal). Among the native species, two are unknown to science (Bryconamericus aff. iheringii and Hypostomus sp. n.) and three are migratory (Leporinus friderici, Megaleporinus obtusidens and Pimelodus maculatus). In this paper, we provide images of species collected. Results indicate that the Guareí River basin is a hotspot of fish diversity in the Upper Paranapanema River, stressing the need for adequate management and conservation actions.

“…Accordingly, the dominant and incumbent Otophysi fishes could have hindered the establishment of poeciliids in the Amazon basin by predation and competition, causing extinction or directly obstructing their colonization (Endler, 2011). In fact, even the establishment of invasive poeciliids, such as guppies ( Poecilia reticulata ), has been limited by biotic resistance from the local fish assemblages in the Neotropics (Dias et al., 2020). Nevertheless, we cannot rule out the possibility that insufficient sampling effort for the inaccessibility of the Amazon region might mask the true poeciliid richness in this basin.…”

Aim Geographical gradients of vertebrate species richness are determined jointly by evolutionary and environmental factors. Support for these factors comes mostly from tetrapods and, recently, marine fishes, but their validity and relative importance in freshwater fishes is not well understood. Here, we describe the species richness gradient for the major component of the viviparous freshwater fishes of the Americas, the poeciliids, and test the effects of evolutionary and environmental factors on this pattern. Location The Americas. Time period Approximatley 56–0 Ma. Major taxa studied Poeciliidae (Teleostei: Cyprinodontiformes). Methods We constructed geographical ranges for 93% (256) of poeciliids to describe and evaluate their species richness gradient. Evolutionary factors (evolutionary time and speciation rate) were derived from a recent phylogeny. Environmental factors were represented as basin area, topographical heterogeneity, energy, climate seasonality and past climatic stability. We tested the influence of these factors with a piecewise structural equation model (pSEM). Results The distribution of Poeciliidae is biased to the Atlantic coast, with species richness showing a bimodal latitudinal gradient, peaking in middle latitudes near the Tropics of Cancer and Capricorn, and exhibiting the highest richness in Middle America. The pSEM showed that this species richness pattern was influenced positively by evolutionary time and past climatic stability and negatively by climate seasonality. Main conclusion The species richness gradient of Poeciliidae has been shaped by the interplay of evolutionary time in addition to current and historical climate. Indeed, regions with high poeciliid richness were those containing by ancient lineages, supporting the time‐for‐speciation effect, and that have experienced low historical stability in temperature and currently show low temperature seasonality. Conversely, species‐poor regions contained younger lineages and experienced greater temperature seasonality. Our study highlights the need to assess jointly the evolutionary, historical and climatic drivers of species richness in order to unravel the causes of diversity gradients.

“…Likewise, high proportions of these two species were reported from the most impaired urban reaches of the Suquía River (Córdoba, Argentina) (Hued & Bistoni, 2005). Moreover, Cyprinodontiformes are widely distributed in the Neotropical region and are notorious for inhabiting deteriorated habitats where few species can thrive (Araujo et al, 2009;Dias et al, 2020). Regarding H. argentinensis, it is also known to withstand low DO levels and to occur in poorly oxygenated waters (Rantin et al, 1992).…”

Low-gradient, prairie streams from the Pampa Plain, Argentina, constitute the southernmost geographic occurrence for many Neotropical fish species. Fish assemblages in Neotropical streams have shown drastic responses to the modification of habitat and water quality. Under this scenario it could be hypothesized that the water quality will be influenced by the anthropic activities and the natural conditions and that the ichthyofauna will be responsive. Therefore, understanding the functioning of these ecosystems is crucial for their conservation in a world with ever-growing anthropic pressures. In order to explore patterns in fish assemblage and water quality under urbanization pressure, the Del Azul stream (Buenos Aires, Argentina) was sampled. The objectives of the study were: (1) to explore trends in water quality and fish assemblage structure along the stream, (2) to study the relationship between fish assemblage structure and water quality, and (3) to pinpoint individual species with potential for biomonitoring. Seven sites were selected along the stream, and they were sampled twice during each of five consecutive summer periods. Through the use of multivariate analysis, we revealed trends in water quality and fish assemblage structure where water quality characteristics were more distinctive of a basin sector than the fish species abundances. Irrespective of that, the Indicator Species Analysis evidenced some key species indicative of given groups of sites sharing similar water quality characteristics. Namely, Cnesterodon decemmaculatus was associated to polluted reaches downstream from the point-source urban effluent, and Cheirodon interruptus, Pimelodella laticeps and Oligosarcus jenynsii to lower salinities and less polluted reaches upstream from the point-source urban effluent. All these species could be useful for biomonitoring temperate Neotropical streams.
