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

Range contraction in a beluga whale population [PDF]
Endangered Species Research, 2010 The small, isolated population of beluga whales Delphinapterus leucas in Cook Inlet, Alaska, USA, has had a distinct contraction in range over the past 3 decades. This contraction is a function of a decline in abundance, evidently caused, at least in part, by high takes during unregu- lated subsistence hunting.

Beluga whale (Delphinapterus leucas) behaviour in the presence of whale-watching vessels
Frontiers in Marine Science, 2023 Beluga whales (Delphinapterus leucas) are social animals that return to the same estuaries each summer season. The Western Hudson Bay belugas in the Churchill River estuary appear to be attracted to boats, resulting in whale-watching being a popular ...
