No evidence of divergence at neutral genetic markers between the two morphologically different subspecies of the most numerous Arctic seabird
Identifying natural populations that might be considered separate units using morphology, genotype or both is important in understanding the process of speciation and for conservation. We examined the relationships between the only two subspecies of the most numerous Arctic seabird, the Little Auk A...

Identifying natural populations that might be considered separate units using morphology, genotype or both is important in understanding the process of speciation and for conservation.
