Skull ecomorphological variation of narwhals (Monodon monoceros, Linnaeus 1758) and belugas (Delphinapterus leucas, Pallas 1776) reveals phenotype of their hybrids. [PDF]

open access: yesPLoS ONE, 2022
Narwhals and belugas are toothed whales belonging to the Monodontidae. Belugas have a circumpolar Arctic and sub-Artic distribution while narwhals are restricted to the Atlantic Arctic.

Serological Detection of Marine Origin Brucella Exposure in Two Alaska Beluga Stocks [PDF]

open access: yesAnimals, 2022
Among emerging threats to the Arctic is the introduction, spread, or resurgence of disease. Marine brucellosis is an emerging disease concern among free-ranging cetaceans and is less well-studied than terrestrial forms.

Machine-Learning Approach for Automatic Detection of Wild Beluga Whales from Hand-Held Camera Pictures [PDF]

open access: yesSensors, 2022
A key aspect of ocean protection consists in estimating the abundance of marine mammal population density within their habitat, which is usually accomplished using visual inspection and cameras from line-transect ships, small boats, and aircraft. However,

Seasonality of social behaviour among immature belugas (Delphinapterus leucas) in managed care

open access: yesPolar Research, 2021
Belugas (Delphinapterus leucas) in managed care have been reported to show seasonal variation in socio-sexual behaviour, hormone levels and respiration rates; however, little is known about the social interactions of wild belugas when they are not in ...

Adults Play but Not Like Their Young: The Frequency and Types of Play by Belugas (Delphinapterus leucas) in Human Care [PDF]

open access: yesAnimal Behavior and Cognition, 2014
While play occurs in many taxa with younger conspecifics engaging in play behaviors more often than older conspecifics, little empirical research currently exists on play by white whales, or belugas, (Delphinapterus leucas).
