Autores: Alonso,M.P; Fernández Iriarte,P.J.
In South America, the Pleistocene was characterized by important environmental changes related to glacial cycles, which had significant effects on the evolutionary history of several marine species. To evaluate the pattern of demographic history and the genetic structure of striped weakfish Cynoscion guatucupa, a 401 bp fragment of the mitochondrial Cytochrome b gene was sequenced from 92 individuals from three coastal areas in Argentina and one in Brazil in the southwestern Atlantic. Haplotype diversity was high, whereas nucleotide diversity was low among all sampling sites. The star-like pattern was not phylogeographically structured, in agreement with the AMOVA analysis. The Fu&amp;#8217;s test was negative and highly significant whereas the mismatch...
