Contrasting genetic patterns and population histories in three threatened redfin species (Cyprinidae) from the Olifants River system, western South Africa

Differentiation occurred in different areas of the same river system in Pseudobarbus phlegethon and two sister species of the serrated redfin lineage (Barbus calidus and Barbus erubescens) of the Western Cape region of South Africa. In an analysis of 27 allozyme loci a deep divergence was found with...

Zusammenfassung:	Differentiation occurred in different areas of the same river system in Pseudobarbus phlegethon and two sister species of the serrated redfin lineage (Barbus calidus and Barbus erubescens) of the Western Cape region of South Africa. In an analysis of 27 allozyme loci a deep divergence was found within P. phlegethon between the Olifants and Doring catchments (seven fixed allelic differences; 0·338
