Analysis of molecular variance (AMOVA) based on ten microsatellite loci in Odontesthes populations from Atlantic Coast, Río de la Plata estuary and Uruguay-Negro River basins.

Three-groups hypothesis among all tested as follows: 1- populations from CA_B, PA_S, YA_S, BA_D and RB_D; 2- populations from R_L, SC_S, SG_S, PA_S, PN_B, G_L, B_P, PR_B and 3- populations from S_L, C_L, CA_L. (See Fig. 1 and Appendix S1).
