Resource Partitioning between Two Piranhas (Serrasalmus gibbus and Serrasalmus rhombeus) in an Amazonian Reservoir [PDF]
The Scientific World Journal, 2017 The exploitation of resources by closely related species with similar niches may be mediated by differences in activity patterns, which may vary in nycthemeral scale and seasonal scale. Piranhas Serrasalmus gibbus and Serrasalmus rhombeus are Neotropical

Endoparasitic fauna of Serrasalmus spp. (Characidae: Serrasalminae) in a neotropical floodplain
Acta Scientiarum: Biological Sciences, 2016 Floodplains systems present complex biodiversity and upper Paraná river floodplain retains a wide variety of terrestrial and aquatic species. Serrasalmus marginatus (nonindigenous species) and Serrasalmus maculatus (native species) are part of this ...

Low Genetic Diversity and Complex Population Structure in Black Piranha (Serrasalmus rhombeus), a Key Amazonian Predator. [PDF]
Ecol EvolUsing a Genotyping‐by‐Sequencing approach across tributaries in the central Amazonia, we found that the black piranha (Serrasalmus rhombeus) exhibits low genetic diversity, pronounced inbreeding, and significant population structure, likely shaped by historical events rather than contemporary factors.

Hydrological Connectivity Enhances Fish Biodiversity in Amazonian Mining Ponds: Insights From eDNA and Traditional Sampling. [PDF]
Mol EcolABSTRACT Artisanal and small‐scale gold mining (ASGM) expansion in the Madre de Dios region of the Peruvian Amazon has transformed primary forests into a novel wetland complex of thousands of abandoned mining ponds. Despite their ecological relevance, post‐mining recovery of these systems remains understudied, particularly regarding fish biodiversity ...

Acoustic homogeneity in the piranha Serrasalmus maculatus
Journal of Fish Biology, 2021 AbstractDifferent studies suggest some social calls could be used in fish identification if their specificity is unambiguously assessed. Sounds of different populations of piranhas Serrasalmus maculatus Kner, 1858 were recorded to determine their homogeneity between rivers inside a single basin (Araguari and Grande River, upper Paraná River basin) and ...

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