First identification of interspecies hybridization in the freshwater stingrays Potamotrygon motoro and P. falkneri (Myliobatiformes, Potamotrygonidae)

2015-02-01

Abstract excerpt

The stingrays Potamotrygon motoro and P. falkneri occurred in sympatry in the Paraguay, Lower and Middle Paraná River, and belong to distinct ecomorphological groups. The construction of a hydroelectric dam in Itaipu in 1982 facilitated the invasion of Upper Paraná River by both species with unpredictable ecological consequences. The aim of the present work was to evaluate the putative hybridization between these...
