A low level of genetic variation in mammalian populations where the census population size is relatively large has been attributed to various factors, such as a naturally small effective population size, historical bottlenecks and social behaviour. The killer whale (Orcinus orca) is an abundant, highly social species with reduced genetic variation. We find(More)
Globally distributed, the bottlenose dolphin (Tursiops truncatus) is found in a range of offshore and coastal habitats. Using 15 microsatellite loci and mtDNA control region sequences, we investigated patterns of genetic differentiation among putative populations along the eastern US shoreline (the Indian River Lagoon, Florida, and Charleston Harbor, South(More)
Cetaceans represent an evolutionary lineage marked by drastic morphological and physiological changes during their adaptation to an exclusively marine existence. In addition, several cetacean species exhibit geographical ranges that encompass different marine environments, with genetic breaks being sometimes consistent with environmental breaks. As such,(More)
