Modelling the effect of varying metabolic rate and cardiac output on estimated tissue and blood O2 and CO2 levels in an extreme deep‐diver, the goose‐beaked whale (Ziphius cavirostris)

Experimental Physiology, Volume 111, Issue 3, Page 765-785, 1 March 2026.
Abstract High‐resolution movement data from Cuvier's beaked, or goose‐beaked whale (Ziphius cavirostris, hereafter Ziphius, n = 8) tag deployments (4.1–19.2 days) were used to estimate blood and tissue O2 and CO2 levels. Acceleration and magnetometry data were used to estimate the locomotion cost (LC) from the relationship between activity and the O2 ...

Three recent ice entrapments of Arctic cetaceans in West Greenland and the eastern Canadian High Arctic

NAMMCO Scientific Publications, 2002
Three ice entrapments of Monodontids have been reported in the western North Atlantic since 1993. Hunters in Disko Bay, West Greenland, discovered one in March 1994 that included about 150 narwhals (Monodon monoceros).

Validation of aerial photogrammetry methods to measure body size, condition and mass in small cetaceans

The Journal of Physiology, Volume 604, Issue 5, Page 1788-1808, 1 March 2026.
Abstract figure legend Unoccupied aerial vehicle (UAV)‐based photogrammetry provides measurements equivalent to traditional hand measurements in bottlenose dolphins. Mass estimates derived from UAV measurements closely match the true body mass of live individuals.

Discriminating Canadian Arctic beluga management stocks using dentine oxygen and carbon isotopes

Endangered Species Research
In the eastern Canadian Arctic, belugas Delphinapterus leucas exhibit genetic and ecological differentiation across their distribution that forms the basis of management stocks for traditional Inuit hunts. Using oxygen and stable carbon isotope ratios in

Variations in thyroid hormone levels in endangered St. Lawrence Estuary belugas: Potential linkage with stress and organohalogen contaminant exposure

Environment International
The St. Lawrence Estuary (SLE) beluga (Delphinapterus leucas) population is highly exposed to an array of contaminants that were identified as one of the causes to the non-recovery of this endangered and declining population.

Do belugas send sound cues? -Experimental verification of blindfolded imitation among beluga-

International Journal of Comparative Psychology
Dolphins are able to successfully coordinate their behavior using audio signals. Therefore, the current study tested whether or not belugas can use sound to exchange information in a cooperative task and verified the mechanisms of the transmission of information during trials. The subjects are two male belugas, Nack and Duke. Nack was trained to rotate

Bester (beluga ♀ × starlet ♂) production and comparing their growth with beluga in Iran

, 2009
Aquaculture for human consuming species is being considered as the first substitution of catching aquatic species due to increase of human population and decrease of wild aquatic stocks. In this study, the hybrid sturgeon Bester (female beluga x male sterlet ) was produced for the first time in Iran. Sperm of 1.35 kg male Acipenser ruthenus was used to
