Genetic structuring of Patagonian toothfish populations in the southwest Atlantic Ocean: the effect of the Antarctic Polar Front and deep-water troughs as barriers to genetic exchange
sites. Mitochondrial DNA (mtDNA) data indicated a sharp genetic division between the Patagonian Shelf ... /North Scotia Ridge and the Shag Rocks/South Georgia samples, whereas microsatellite data showed much ... these data indicate that the APF, as a barrier to larval dispersal, is the major inhibitor of genetic ...
