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 ...

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 ...

Age and growth of the endemic groovebelly stingray (Dasyatis hypostigma), a heavily exploited batoid in the Brazilian Meridional Margin (21–34° S)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Life‐history data are often lacking for exploited elasmobranchs, jeopardizing proper management and conservation measures for this vulnerable group. Herein, we provided age and growth estimates for the groovebelly stingray (Dasyatis hypostigma), a medium‐sized, heavily exploited batoid endemic to the southwestern Atlantic Ocean.
