Última Genetic variability and evidence of founder effect in Hemiodus orthonops (Characiformes: Hemiodontidae) from the upper Paraná River basin, Brazil Biological Sciences Marques, Liégie Alher; Renesto, Erasmo.  Hemiodus orthonops is a small fish of the Hemiodontidae family, order Characiformes, with a maximum of 25 cm standard length. Until recently, H. orthonops was an endemic species from the Paraná-Paraguay basin and it was absent from the upper Paraná River basin. Since 2008, it has started to be collected in the upper Paraná River, representing up to 10% of catches. Two population samples of H. orthonops from two localities of the upper Parana River basin (Porto Camargo and Porto Figueira) were analyzed using the allozymes electrophoresis technique. Twenty-one enzymatic loci were detected. The population sample from Porto Camargo displayed a genetic variability (He = 0.1061) higher than that from Porto Figueira (He = 0.0580) and homozygote excess in both of...

Beetles of the species Sitophilus oryzae and S. zeamais are pests of great economic importance since they attack not only rice and maize but also several other cereals. In fact, these beetles are one of the most visible threats to sustainable food production. Current study estimated the genetic variability of S. oryzae in two samples, one from the State of Paraná (PR), Brazil, and another from the state of Rio Grande do Sul (RS), Brazil, and a sample of S. zeamais from the State of Santa Catarina (SC), Brazil. Isozyme electrophoresis in starch gel technique was employed to analyze eight enzyme systems (AAT, ACP, GDH, GPI, IDH, MDH, PGM and ME). Average heterozygosity rates were 0.0091, 0.0100 and 0.0000 and expected heterozygosity rates were 0.0419, 0.0452...
