Hybridization does not currently pose conservation concerns to murres in the Atlantic

Hybridization can negatively impact one or both taxa involved and therefore pose conservation concerns. Climate change is expected to increase the rate of hybridization particularly in polar regions, and so investigating hybridization in Arctic and Antarctic species is important for conservation. Hybridization and genetic introgression have been observed between Pacific populations of thick-billed (Uria lomvia) and common murres (Uria aalge),...
