Figure S1-Distribution of S. alburnoides in Portugal and areas of sympatry with other Squalius species involved in the S. alburnoides polyploidy reproductive complex. Distribution of S. alburnoides in Portugal and areas of sympatry with other Squalius species involved in the S. alburnoides polyploid reproductive complex. Rivers from which S. alburnoides and S. pyrenaicus were sampled are marked in red in the first panel: a) Ocreza; b) Sorraia, c) Caia; d) Murtega; e) Foupana and f) Almargem. In the second panel the major Portuguese river basins are identified.
