Genetic structuring of Salminus hilarii Valenciennes, 1850 (Teleostei: Characiformes) in the rio Paraná basin as revealed by microsatellite and mitochondrial DNA markers Neotropical Ichthyology
Silva,Juliana Viana da; Hallerman,Eric M.; Orfão,Laura Helena; Hilsdorf,Alexandre Wagner Silva.
Genetic variation of Salminus hilarii was assessed by screening microsatellite loci and mitochondrial D-loop DNA across four sampling in the upper rio Paraná basin of Brazil. Genetic diversity - measured as mean expected heterozygosity (0.904) and mean number of alleles across populations (13.7) - was reasonably high. Differentiation of microsatellite allele frequencies among populations was shown to be low but significant by AMOVA Φ ST (0.0192), and high by D EST (0.185). D-loop variation was high, with haplotypic diversity of 0.950 and nucleotide diversity of 0.011. Mitochondrial DNA-based estimates for population differentiation were high, with an overall Φ ST of 0.173. The results of tests of nuclear and mitochondrial variation yielded no unequivocal...
