Genetic structure of bisexual and parthenogenetic populations of Artemia from Italian brackish-hypersaline waters
Provedor de dados: 5

Eight populations of Artemia displaying different reproduction modalities (amphigonic vs. parthenogenetic) and ploidies (diploid vs. polyploid) have been collected from Italian salt-works or brackish coastal lagoons, and their genetic structure has been investigated using allozyme electrophoresis. The results obtained on genetic differentiation showed that the Tyrrhenian bisexual samples (A. salina) are genetically homogeneous even between populations located in relatively faraway sites (Sardinia-Latium), having a moderate gene flow assisted by migratory waterfowl. The parthenogenetic samples (A. parthenogenetica) are genetically well differentiated both from the bisexual ones and among them, even when characterised by the same ploidy. Each sample presents...
