Evaluating 36 years of fishing sustainability in a large reservoir [PDF]

Scientific Reports
Various fishing activities are common economic practices in large hydroelectric reservoirs, such as Itaipu. Consequently, the Itaipu company has monitored artisanal commercial fishing since the formation of its reservoir. In this study, we used long-term

Linking rivers, mixing faunas: How artificial connectivity between the Middle and Upper Paraná River basins shapes fish diversity in a tributary of the Itaipu Reservoir, Brazil. [PDF]

J Fish Biol
Abstract This work aimed to investigate the distribution and occurrence of fish species along the São Francisco Falso Braço Norte (SFFBN) River basin, a tributary of the Middle Paraná River basin now artificially connected to the Upper Paraná ecoregion, to evaluate how such connectivity may affect the biogeographic distribution and regional composition

Deciphering the complex life cycle and partial migration of an ecological engineer and critical Neotropical fishery species, Prochilodus costatus. [PDF]

J Fish Biol
Abstract Understanding complex migration patterns, including drivers of partial migration and habitat use, is challenging but essential for conservation, as it determines a species' adaptative capacity in the face of environmental change and anthropogenic threats.

Distribution modelling for Neotropical freshwater stingrays Potamotrygon brachyura and Potamotrygon motoro (Myliobatiformes, Potamotrygonidae) in the Uruguay River basin. [PDF]

J Fish Biol
Abstract This study aimed to identify geographical distribution patterns of the giant short‐tailed river stingray Potamotrygon brachyura and the motoro stingray Potamotrygon motoro in the Uruguay River basin. Data on presence/absence of stingrays were based on fishers' knowledge accessed by interviews through expeditions in Brazil, Argentina and ...

Diet of Iheringichthys labrosus (Pimelodidae, Siluriformes) in the Itaipu Reservoir, Paraná River, Brazil-Paraguay

Brazilian Archives of Biology and Technology, 2001
Iheringichthys labrosus is a secondary commercial fish species in the Itaipu Reservoir, but it is important in other reservoirs of the basin. However, little information exists about this species in the literature.

Aquatic macrophytes of Itaipu Reservoir, Brazil: survey of species and ecological considerations

Brazilian Archives of Biology and Technology, 1999
In a survey of the aquatic macrophytes of the Itaipu Reservoir, we identified 62 taxa in 25 families and 42 genera. The highest number taxa was observed for the emergent macrophytes (40 taxa).

Reproductive Strategies of Plagioscion squamosissimus Heckel, 1840 (Osteichthyes Sciaenidae) in the Itaipu Reservoir, Brazil

Brazilian Archives of Biology and Technology, 2002
Plagioscion squamosissimus is a dominant species in the Itaipu reservoir and has a significant role in the regional economy. The aim of the present research was the investigation of the curvina's reproductive strategies during the first years of the ...

Non-Native Species Abundance Decreases the Co-Occurrence Between Native and Non-Native Species Through Time at Any Phylogenetic Distance. [PDF]

Ecol Lett
We investigate how non‐native species can impact native species in a 30‐year time scale by estimating the co‐occurrence between native and non‐native species pairs. We show that interannual variability of non‐native species abundance could be more important than long‐term abundance trends in determining the effects of non‐native species through time ...

Landscape Genomics and Evolutionary History of <i>Megamelus scutellaris</i>, a Biocontrol Agent of the Invasive Water Hyacinth (<i>Pontederia crassipes</i>). [PDF]

Evol Appl
ABSTRACT Understanding the evolutionary history of biological control agents in their native ranges is crucial for improving their selection, establishment, and performance across environmentally diverse regions. Phytophagous insects that specialize on aquatic plants offer particularly valuable models, as their evolutionary trajectories may be shaped ...

Establishing new grid-size-dependent attributes to rank areas of endemism for conservation priorities. [PDF]

Cladistics
Abstract Delineating Areas of Endemism (AEs) is crucial for identifying priority areas for biodiversity conservation in a spatial planning framework. Endemicity Analysis in the NDM/VNDM software is one of the primary methodologies for its delineation.
