Thermal reference points as an index for monitoring body temperature in marine mammals [PDF]

, 2015
BACKGROUND Monitoring body temperature is essential in veterinary care as minor variations may indicate dysfunction. Rectal temperature is widely used as a proxy for body temperature, but measuring it requires special equipment, training or ...

Intraspecific variation of cochlear morphology in bowhead and beluga whales

The Anatomical Record, Volume 309, Issue 6, Page 1514-1529, June 2026.
Abstract The bony labyrinth of the petrosal bone, a distinctive feature of mammal skulls, is often identified in micro‐computed tomography imaging to infer species' physiological and ecological traits. When done as part of a comparative study, one individual specimen is normally considered representative of a species, and intraspecific variation is ...

Of Whales and Genes: Unraveling the Physiological Response to Stressors in Belugas (Delphinapterus leucas) at the Molecular Level

Journal of Zoological and Botanical Gardens, 2021
Marine mammals, now more than ever, are exposed to environmental and anthropogenic stressors. A better understanding of stress physiology in marine mammals is warranted in order to assist in conservation efforts.

Concentrations of Polychlorinated Biphenyls (PCB’s), Chlorinated Pesticides, and Heavy Metals and Other Elements in Tissues of Belugas, Delphinapterus leucas, from Cook Inlet [PDF]

, 2000
Tissues from Cook Inlet beluga whales, Delphinapterus leucas, that were collected as part of the Alaska Marine Mammal Tissue Archival Project were analyzed for polychlorinated biphenyls (PCB’s), chlorinated pesticides, and heavy metals and other elements.

Genetic and Ecological Divergence Between Northwest Atlantic Killer Whale Populations

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Killer whale (Orcinus orca) populations exhibit substantial genetic, ecological, and morphological differences across their global distribution. In this study, we use whole‐genome resequencing and compound‐specific stable isotope analysis of amino acids to show concurrent genetic and ecological differentiation in two relatively understudied killer ...

Stranded beluga (Delphinapterus leucas) calf response and care: reports of two cases with different outcomes

Polar Research, 2021
Given the remote, rugged areas belugas typically inhabit and the low rehabilitation success rate with any cetacean, it is rare to have the opportunity to rescue a live-stranded beluga.

Element concentrations in tissues reveal spatial structure of Atlantic walrus management stocks

The Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
Differences in tissue element concentrations confirm geographic differentiation between 2 of Canada's walrus management stocks but reveal additional spatial structure within the largest stock that may have management implications. Abstract Ensuring harvested animal populations are managed at appropriate scales requires an understanding of underlying ...

Low prevalence of zoonotic food-borne parasites Toxoplasma gondii and Trichinella spp., but high prevalence of a potential marine Sarcocystis spp., in Eastern Beaufort Sea beluga whales (Delphinapterus leucas) harvested in the Canadian Arctic

Arctic Science
Beluga whales (Delphinapterus leucas (Pallas, 1776)) are traditional food sources for Inuit communities in the Canadian Arctic. In response to community concerns about zoonotic parasites (Toxoplasma gondii and Trichinella spp.), the aim of this study was
