Genomics of white-tailed eagle (Haliaeetus albicilla) in the North-Atlantic islands reveal low diversity and substantial inbreeding in comparison with the mainland populations
Using whole genome shotgun sequences from 92 white-tailed eagles (Haliaeetus albicilla) sampled from Greenland, Iceland, Norway, Denmark, Estonia, and Turkey between 1885-1950 and after 1990, we investigate the genomic variation within countries over time, and between countries. Clear genetic differ...
