- Highly divergent genetic clades of Phoxinus were detected in the western Balkans.
- The two species view proposed by morphologists was not supported.
- Revision of Phoxinus classification in the studied area is suggested.
- The clades extend along the Adriatic area crossing the watershed boundaries.
- Specific genetic signatures point to the possibility of underground fish dispersion.
This study aimed to evaluate the phylogeographic distribution of Phoxinus phoxinus sensu lato populations in the Balkan Peninsula using molecular methods. For the western Balkan Peninsula, two species (Danubian P. phoxinus and Adriatic P. lumaireul) have been suggested, but not confirmed by subsequent morphological studies or by genetic data. For the present study, more than 300 specimens were collected from the western Balkans.A partial sequence of the mt cyt b gene analysed using Bayesian and ML methods revealed several well-supported clades, with distances ranging from 4% to 11%. The clades were corroborated by RAG1 sequence analysis. Thus, the molecular analysis points to a multispecies complex of Phoxinus sp. with ranges of the clades extending north-west to south-east along the western Balkan Peninsula. In addition, the dispersion of fish through subterranean water connections in karst is indicated.
