A shift in foraging behaviour of beluga whales Delphinapterus leucas from the threatened Cumberland Sound population may reflect a changing Arctic food web

Endangered Species Research, 2016
Cumberland Sound, an inlet on Baffin Island, Nunavut, Canada, is undergoing changes in sea ice cover, which is affecting the marine food web. A small population of beluga whales Delphinapterus leucas inhabits Cumberland Sound year round and this ...

Summer distribution and habitat preference of beluga whale social groups in the Eastern Beaufort Sea

Arctic Science, 2023
In social animals, group composition can cause variations in individual needs that can influence responses to habitat trade-offs, such as predator exposure or foraging opportunities.

The Genome of the Beluga Whale (Delphinapterus leucas) [PDF]

Genes, 2017
The beluga whale is a cetacean that inhabits arctic and subarctic regions, and is the only living member of the genus Delphinapterus. The genome of the beluga whale was determined using DNA sequencing approaches that employed both microfluidic partitioning library and non-partitioned library construction.

First Non‐Invasive Monitoring of Fecal Steroids in Greater Caribbean Manatees (Trichechus manatus manatus)

Zoo Biology, EarlyView.
This study established the first fecal hormonal reference values (P4/E2) for the Greater Caribbean manatee. Using non‐invasive ELISA, the authors found no significant differences between mature and immature females, highlighting that long‐term monitoring and ultrasounds are essential to fully understand their complex reproductive cycles.

Secularism, Gender and Masculinity in Nineteenth‐Century Cremation in Europe and the USA

Gender &History, EarlyView.
ABSTRACT This essay explores, from transnational perspectives, the early history of modern cremation, which developed in the long nineteenth century with secularist connotations. I argue that the beginnings of modern cremation were shaped by bourgeois men who claimed certain identifiers for themselves in a gendering and Othering way.

Distribution and migrations of cetaceans in the Russian Arctic according to observations from aerial ice reconnaissance

NAMMCO Scientific Publications, 2002
This paper is based on 748 observations of belugas (Delphinapterus leucas) and 382 observations of baleen whales in the Russian Arctic, the majority of the data provided by aerial reconnaissance of sea ice (ARSI).

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

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

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.

Cache‐Cache: Dans les souffles du Grand Fleuve…

Anthropology of Consciousness, EarlyView.
ABSTRACT Between ventriloquism and divination, devotion and consecration, an old and sublime marine game unfolds each day, with living breaths shared in the waters of the great river. In Tadoussac, on the north shore of the St. Lawrence Estuary, at the mouth of the Saguenay, the rumor of whales has long resonated.
