Population genetic structure and body shape assessment of Pagrus pagrus (Linnaeus, 1758) (Perciformes: Sparidae) from the Buenos Aires coast of the Argentine Sea Neotropical Ichthyology
Porrini,Leonardo P.; Iriarte,Pedro J. Fernández; Iudica,Celia M.; Abud,Eddie Aristizabal.
This study highlights the analysis of the morphological and genetic variation of the common sea bream Pagrus pagrus, and compares its two main areas of concentration: the northern (35ºS - 38ºS) and the southern areas (39ºS - 41ºS) of the Buenos Aires coast of the Argentine Sea. Body shape characterization presented two significantly different morphotypes (Wilks' Lambda=0.224, P<0.001). Northern individuals displayed a higher middle area while southern ones were smaller and their caudal peduncle was shorter. The northern and southern areas did not yield significant genetic differences either with the control region or the microsatellite loci, revealing that P. pagrus is not genetically structured. However, individuals from these areas should not be...
