Photographic evidence of tagging impacts for two beluga whales from the Cumberland Sound and western Hudson Bay populations

Arctic Science, 2022
Beluga whale (Delphinapterus leucas (Pallas, 1776)) movements, habitat use, and diving behaviour have been studied using satellite-linked transmitters for decades.

The T‐Cell Response Mechanism in Human Papillomavirus‐Associated Cervical Cancer and New Strategies for Immunotherapy

iNew Medicine, EarlyView.
ABSTRACT Human papillomavirus (HPV) is a double‐stranded DNA virus that infects human skin and mucosal tissues exclusively. The German scientist Harald zur Hausen was awarded the 2008 Nobel Prize in Physiology or Medicine for his discovery of the link between HPV infection and cervical cancer.

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.

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 ...

Sea Ice and Whales from Space: The Feasibility of Using Satellite Imagery for Monitoring Beluga Whales in Winter

Journal of Marine Science and Engineering
Very-high-resolution (VHR) satellite imagery has expanded the scale at which researchers can monitor marine mammals in remote regions and improved monitoring efforts in data-deficient areas.

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.

Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

Journal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

Estimating beluga whale abundance from space: using drones to ground‐validate VHR satellite imagery

Remote Sensing in Ecology and Conservation
Routine monitoring of cetaceans is imperative for understanding their population trends and making informed management decisions. However, the inherent nature of cetaceans and the marine ecosystems they inhabit make annual population surveys logistically
