Comparative Respiratory Physiology in Cetaceans
Frontiers in Physiology, 2020 In the current study, we used breath-by-breath respirometry to evaluate respiratory physiology under voluntary control in a male beluga calf [Delphinapterus leucas, body mass range (Mb): 151–175 kg], an adult female (estimated Mb = 500–550 kg) and a ...

An epigenetic clock to estimate the age of living beluga whales [PDF]
Evolutionary Applications, 2020 Abstract DNA methylation data facilitate the development of accurate molecular estimators of chronological age or “epigenetic clocks.” We present a robust epigenetic clock for the beluga whale, Delphinapterus leucas , developed for an endangered population in Cook Inlet ...

Propagation of beluga whale echolocation signals [PDF]
The Journal of the Acoustical Society of America, 1984 The propagation characteristics of high-frequency echolocation signals (peak energies above 100 kHz) of the beluga whale, Delphinapterus leucas were determined by a series of measurements conducted while the animal performed a target-detection task. The whale was trained to station on a “bite-plate” so that its projected beam could be measured in the ...

Disrupting the herd: Recreational boating alters group dispersion within beluga whale herds
The Journal of Wildlife Management, EarlyView.Recreational boating in beluga habitat remains poorly documented. Using land‐based observations in the Saguenay Fjord (Quebec, Canada), we show that increasing recreational boat numbers are associated with a higher probability of changes in beluga herd dispersion, suggesting behavioral disturbance and the need to integrate recreational boating into ...

Pêches des bélugas, des anguilles et des esturgeons noirs de l’estuaire du St-Laurent
Revue d'ethnoécologie, 2018 This paper presents an ethnographic examination of beluga whale, eel and black sturgeon fisheries, focusing more particularly on their exploitation, commodification and conservation.

Lateralized sound production in the beluga whale (Delphinapterus leucas) [PDF]
Journal of Experimental Biology, 2020 Like other toothed whales, belugas produce sound through pneumatic actuation of two phonic lip pairs, but it is unclear whether both pairs are actuated concurrently to generate a single sound (the dual actuation hypothesis) or laterally in the production of their rich vocal repertoires.
