doi:10.1111/j.1469-1795.2009.00270.x In our recent study on the population genetic structure of short-beaked common dolphins Delphinus delphis in south-ern Australia (Bilgmann et al., 2008) we unequivocally showed a high level of genetic differentiation between the local common dolphin population in South Australia (SA) and the one in south-eastern Tasmania. The differentiation found in short-beaked common dolphins over this relatively small geographic scale of c. 1500 km is unusual for such a wide ranging and highly mobile species (Bilgmann et al., 2008). The genetic subdivision and the very low migration rates between the populations reported in our study has important implications for the management of dolphin interactions with the purse-seine fishery in SA; these inter-actions have lead to serious concerns over the long-ter
