Abstract

Fatty, acid profiles were used to investigate aspects of bottlenose dolphin Populations around the Azores archipelago. Biopsy samples were obtained from 70 dolphins during the period 2002-2004. No statistically significant differences in profiles were found between different island groups, between sexes or between year of sampling. Thus no evidence was Seen for island group Fidelity, in contrast to bottlenose dolphins found around similar island groups Such as the Hawaiian archipelago or the Bahamas. The findings are consistent with concurrent genetic and photo-Identification Studies oil dolphins in the Azores.
