Population structure and phylogeography of the short-tailed stingray, Dasyatis brevicaudata (Hutton 1875), in the Southern Hemisphere.

Abstract excerpt

There is accumulating evidence that the degree of vagility explains little of the extent of population subdivision found within elasmobranch species. Instead, patterns of gene flow in elasmobranchs appear more closely linked to the presence of dispersal barriers, either physical or biological.
