Dear All,

The following paper has been recently published on-line in  
Conservation Genetics.


Risso’s dolphins (Grampus griseus) in UK waters are differentiated  
from a population in the Mediterranean Sea and genetically less diverse

Stefania Gaspari, Sabina Airoldi,  A. Rus Hoelzel

Abstract The Risso’s dolphin (Grampus griseus) has a worldwide  
distribution, but little is known about their population genetic  
structure. Local coastal populations are never known to be abundant,  
and are sometimes under anthropogenic impact. Therefore the question  
of regional differentiation by genetic drift and overall diversity  
levels is of conservation interest. Here we present preliminary data  
that clearly indicate genetic differentiation and lower genetic  
diversity of a population sampled in UK waters (primarily from the  
Western Isles, Scotland) compared to a Mediterranean sample.  
Significant differentiation was found in comparison with a sample  
from the Mediterranean for both microsatellite DNA markers (FST =  
0.0296) and mtDNA sequence data (FST = 0.260; /ST = 0.542). Allelic  
diversity was lower in the UK for nearly all loci.

Kindest Regards,
Stefania Gaspari
