Estimates of DNA polymorphism based on ten microsatellite loci in Odontesthes populations from SW Atlantic Coast, Río de la Plata estuary and Uruguay-Negro River basins.

Total number of alleles (AT); number of alleles (A); allelic richness based on minimum sample size of 2 diploid individuals (rA); observed (HO) and expected (HE) heterozygosity; significant departure from Hardy-Weinberg equilibrium (P) (PPopulations were ascribed to four taxa. Oa included only population from Garzon Lagoon (GL) collecting site. (See Fig. 1 and Appendix S1).
