Genetic isolation of a now extinct population of bottlenose dolphins ( Tursiops truncatus)
A number of dolphin species, though highly mobile, show genetic structure among parapatric and sometimes sympatric populations. However, little is known about the temporal patterns of population structure for these species. Here, we apply Bayesian inference and data from ancient DNA to assess the st...
