Skin Cortisol and Acoustic Activity: Potential Tools to Evaluate Stress and Welfare in Captive Cetaceans

Animals, 2023
As people’s focus broadens from animals on farms to zoos and aquaria, the field of welfare science and the public’s concern for animal welfare continue to grow.

Sharing Is Caring?—Pathogens and Pathogen‐Specific Antibodies in Arctic Endemic Seal Species and the Newly Sympatric Harbor Seals in Kongsfjorden, Svalbard

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Climate change associated transformations of Arctic marine ecosystems are having detrimental impacts on Arctic endemic marine mammals. However, warming conditions are providing new habitats for temperate marine mammals, some of which are expanding into Arctic regions, posing a threat of novel pathogen introduction and disease transmission.

Laterality of Eye Use by Bottlenose (Tursiops truncatus) and Rough-toothed (Steno bredanensis) Dolphins While Viewing Predictable and Unpredictable Stimuli [PDF]

, 2020
Laterality of eye use has been increasingly studied in cetaceans. Research supports that many cetacean species keep prey on the right side while feeding and preferentially view unfamiliar objects with the right eye.

Diving behaviour of adult male white whales (Delphinapterus leucas) in Svalbard, Norway

Polar Research, 2019
White whales (Delphinapterus leucas) in Svalbard remain near the coast much of the year, spending most of their time in front of tidewater glaciers. In this article, the diving behaviour of adult male white whales in Svalbard (N = 16) is presented based ...

Choroid plexus papilloma in a beluga whale (Delphinapterus leucas) [PDF]

Journal of Veterinary Diagnostic Investigation, 2016
We report herein a choroid plexus papilloma in a beluga whale ( Delphinapterus leucas). This case was positive for choroid plexus tumor marker Kir7.1 on immunohistochemistry. These results and the high conservation of Kir7.1 across species at the amino acid sequence level strongly suggest that antibodies directed against Kir7.1 not only can be ...

Correcting Lipid Extraction Effects on Nitrogen Isotopic Values (δ15N) in Cetacean Skin

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Stable isotopes of carbon (δ13C) and nitrogen (δ15N) are widely used to study the feeding ecology of cetaceans, as they provide critical insights into diet and migratory behaviors. Lipids in tissues may bias the interpretation of δ13C. Because of this, lipids need to be extracted before measuring stable isotope ratios, but their removal may ...

Foraging ecology of ringed seals (Pusa hispida), beluga whales (Delphinapterus leucas) and narwhals (Monodon monoceros) in the Canadian High Arctic determined by stomach content and stable isotope analysis [PDF]

Polar Research, 2015
Stomach content and stable isotope analysis (δ13C and δ15N from liver and muscle) were used to identify habitat and seasonal prey selection by ringed seals (Pusa hispida; n=21), beluga whales (Delphinapterus leucas; n=13) and narwhals (Monodon monoceros;

From Participation to Management: Coconstructing Sustainable Practices in the Saint Lawrence Beluga Habitat

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 3, March 2026.
ABSTRACT The Saint Lawrence Beluga population (Delphinapterus leucas), classified as an endangered species since 2014, continues to decline despite various recovery efforts. A growing concern is the impact of recreational boating on this population. Although the stress caused by boat noise and presence is well documented, the regulation and management ...

Inventaire systématique et paléoécologie des mammifères marins de la Mer de Champlain (fin du Wisconsinien) et de ses voies d’accès [PDF]

, 1988
À la fin du Wisconsinien supérieur, entre environ 12 400 et 9300 BP, la Mer de Champlain a inondé une vaste région allant de Québec au lac Ontario. Dans ces eaux progressivement dessalées, riches en plancton et poissons, plusieurs espèces de baleines ...
