The Genome of the Beluga Whale (Delphinapterus leucas). [PDF]

Genes (Basel), 2017
The beluga whale is a cetacean that inhabits arctic and subarctic regions, and is the only living member of the genus Delphinapterus. The genome of the beluga whale was determined using DNA sequencing approaches that employed both microfluidic partitioning library and non-partitioned library construction.

Group structure and kinship in beluga whale societies. [PDF]

Sci Rep, 2020
AbstractEvolutionary explanations for mammalian sociality typically center on inclusive-fitness benefits of associating and cooperating with close kin, or close maternal kin as in some whale societies, including killer and sperm whales. Their matrilineal structure has strongly influenced the thinking about social structure in less well-studied ...
