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

open access: yesJournal of Fish Biology, EarlyView.
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

Morphological and molecular evidence reveals a new species of Characidium from the Ucayali‐Urubamba Piedmont, Peru, and novel molecular clades are proposed within the genus

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of Characidium is described from the Urubamba River basin, within the Ucayali‐Urubamba Piedmont ecoregion, Peru. The new species can be readily distinguished from all congeners, except Characidium cacah, Characidium chicoi, Characidium helmeri, Characidium mirim, Characidium nana, Characidium nupelia, Characidium sterbai ...

Spatial habitat partitioning enables coexistence of three Gobiidae species in estuarine environments

open access: yesJournal of Fish Biology, EarlyView.
Abstract This study examines resource partitioning (feeding morphology, diet and habitat partitioning) among three gobiid species, the Knysna sandgoby Psammogobius knysnaensis, the prison goby Caffrogobius gilchristi and the river goby Glossogobius callidus, within an estuarine environment.

A fractal pattern of hierarchical genetic population structure in mixed stocks across fish segregated by dams revealed by genomic resources for curimba Prochilodus lineatus

open access: yesJournal of Fish Biology, EarlyView.
Abstract Genomic resources, new microsatellite markers and a novel observation of a fractal pattern in the genetic population structure are presented for curimba, Prochilodus lineatus, a freshwater migratory model species of South America. Our main goals were to investigate the presence of mixed fish stocks and the effects of damming‐induced ...

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

open access: yesJournal of Fish Biology, EarlyView.
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.

Amazonian drought of 2023: Environmental conditions relevant to fishes

open access: yesJournal of Fish Biology, EarlyView.
Abstract This paper provides a platform for the following studies within this Special Issue. ‘Ecophysiology of fishes in the two great tributaries of the Amazon in the Anthropocene’. It documents the water quality conditions and accompanying zooplankton community structure and biomass relative to fish health in the Rio Negro and Rio Solimões during the
