Gaspari S, Azzellino A, Airoldi S, Hoelzel AR (2007) Molecular  
Ecology. Social kin associations and genetic structuring of striped  
dolphin populations (Stenella coeruleoalba) in the Mediterranean Sea.
doi: 10.1111/j.1365-294X.2007.03295.x


We investigated hierarchical patterns of genetic subdivision, and  
assessed kinship within and between social groups of striped dolphins  
(Stenella coeruleoalba) in the Tyrrhenian Sea. A total of 165 samples  
were analysed at eight microsatellite DNA loci, including outgroup  
samples from the Adriatic, Scotland and Spain for population-level  
comparisons. We found population genetic structure within the  
Mediterranean basin, including small but significant differentiation  
between the Adriatic and Tyrrhenian Seas (FST= 0.0047,P= 0.008), and  
between putative ‘inshore’ and ‘offshore’ (FST= 0.0217,P= 0.005)  
populations in the Tyrrhenian Sea. Assessment of kinship within and  
among 12 association groups showed higher average kinship for females  
within than between groups, and smaller groups showed higher average  
kinship. Comparisons of relatedness for both sexes showed a  
significant difference between males and females, with females more  
likely to associate with adult kin. Together these data emphasize the  
importance of the social cohesion of kin in small groups to the  
structuring of striped dolphin populations in this environment.
