Article
Flow regulation through dams increases water and energy security for society but also threatens the natural equilibrium of river basins, leaving ecosystems and communities more vulnerable. While recovering flow regime dynamics to mitigate environmental impacts is a necessary goal, its effective implementation depends on the capacity to predict the...

The cichlid Astronotus crassipinnis (Heckel, 1840) known as “oscar” or “apaiari” is native to the Amazon basin and presents an omnivorous feeding habit, with a tendency to carnivory. The species was introduced in the upper Paraná River floodplain, where the trophic strategies adopted by the species are not well-known. The objective of this study wa...

Landscape dynamics and river network rearrangements are widely thought to shape the diversity of Neotropical freshwater fishes, the most species-rich continental vertebrate fauna on Earth. Yet the effects of hydrogeographic changes on fish dispersal and diversification remain poorly understood. Here we integrate an unprecedented occurrence dataset...
Article
Full-text available
Prey fish species can respond to the presence of predators using a variety of antipredatory behaviors to reduce their risk of being consumed. As such behaviors may also imply fitness costs, the ability of prey to perceive and appropriately respond to the predation threat is crucial to determine the persistence of its populations. Little is known wh...

• Freshwater ecosystems, providing valuable goods and services to humans, have been subjected to multiple human impacts, among which climate change plays a central role in threats to species. It is expected that protected areas, the cornerstone of biodiversity conservation efforts, will assume a decisive role in protecting freshwater species from t...
Article
Detecting a potentially invasive introduced species is crucial for efficient conservation strategies. We recorded the first occurrences of the "pirambeba" Serrasalmus geryi in the upper Paraná River floodplain, Brazil, in December 2019. A long-term ecological research program (PELD site 6) has been monitoring the region since 1986. One specimen was...

Our objective was to evaluate the effectiveness of protected areas (PAs) in the Paraná-Paraguay basin on multiple facets of ichthyofauna, both currently and in future climate change scenarios, based on reaching the 17% of conserved terrestrial and inland water defined by Aichi Target 11. Analyses were carried out vis-à-vis a distribution of 496 nat...
Article
Anthropogenic impacts are altering ecosystems, especially aquatic habitats, resulting in the loss of critical biodiversity. This study aimed to evaluate the influence of human pressure, as surrogated by the human footprint index (HFI), on the functional diversity of fish assemblages from 109 Neotropical reservoirs while considering covariates such...
Article

The flood pulse is the main driving force for communities’ structure and functioning in river-floodplain systems. High synchrony exists between the hydrological cycle and reproductive cycle events for several fish species. However, species with different reproductive strategies can respond in different ways to the flood regime. Thus, this study int...

Abstract: Body size is a trait that results from evolutionary and ecological processes. Body size not only provides information on the physical condition of individuals but also on the shift in community structure across space and time. Here, we aimed to investigate whether the body size of the migratory fishes changed over time and to ascertain...

The environmental changes caused by humans have impacted the survival of species. The deforestation and climate change, are the main cause of the increase in the importance the protected areas on the landscape. Thereby, identify the priority areas for conservation of the frugivorous fish (Piaractus mesopotamicus) on the Paraná-Paraguay basin, consi...

This study uses species distribution modeling and physiological and functional traits to predict the impacts of climate change on native freshwater fish in the Murray-Darling Basin, Australia. We modelled future changes in taxonomic and functional diversity in 2050 and 2080 for two scenarios of carbon emissions, identifying areas of great interest...

Astyanax biotae Castro & Vari, 2004 was only known from the type locality, a first-order stream from the lower Paranapanema River, a left bank tributary from the upper Paraná river basin. We report A. biotae from the Ivinhema River, rio do Peixe and other tributaries of Paranapanema River, expanding its distribution to both margins of the Paraná Ri...

Flood pulses are the main force driving the dynamics of aquatic communities in floodplains. The responses of communities to environmental changes following flood pulses usually demand a time lag to appear and reach the climax. We assembled a data set of 16 years of fish samplings to assess the relationship between water level and four functional di...

1. The long-term impact of river regulation on fish functional diversity by a dam immediately upstream from the upper Paraná River floodplain, Brazil, was evaluated. It was expected that the resulting alterations in natural flow, downstream from the dam, would negatively impact fish species, resulting in a functional simplification of the ichthyofa...

Trabajo del río Paraná en Argentina, que relata como la intervención del cauce natural de los ríos, puede afectar a los peces que allí habitan.
Article
Full-text available
Floodplain river systems are extremely dynamic environments, where alternating dry and flooded periods affect the availability of food resources for fish. For piscivores, during drought years, a decreased availability of prey is expected, resulting in diets dominated by fewer items, narrower trophic niches with high dietary overlap. During floods,...

This study evaluated the relationship between the young of year (YOY) abundance of migratory fish species and the interannual variations in the duration and delay of floods in the Upper Paraná River floodplain. YOY of the most abundant migratory species Brycon orbignyanus, Hemisorubim platyrhynchos, Leporinus elongatus, Leporinus macrocephalus, Lep...

The objective of this study was to evaluate the combination of some sampling gears operated in different biotopes on fish species richness and species composition. Fish were collected from five different types of biotopes in the Upper Parana River floodplain, according to the most suitable sampling gear for the characteristics of each biotope. A to...
