An overview of genetic relationships of Canadian and adjacent populations of belugas (Delphinapterus leucas) with emphasis on Baffin Bay and Canadian eastern Arctic populations

NAMMCO Scientific Publications, 2002
Our current knowledge of the molecular genetics of High Arctic beluga (Delphinapterus leucas) populations (West Greenland, Lancaster Sound/Barrow Strait, Grise Fiord) and populations that are related (southeast Baffin, Beaufort Sea), is presented.

Spatially explicit models of density improve estimates of Eastern Bering Sea beluga (Delphinapterus leucas) abundance and distribution from line-transect surveys [PDF]

PeerJ
We investigate spatially explicit models and ensemble modeling techniques for estimating animal abundance from line-transect survey data. Spatially explicit models are expected to be statistically more efficient, resulting in more precise abundance ...

Beluga whale body condition: evaluating environmental variables on beluga body condition indicators in the Tarium Niryutait MPA, Beaufort Sea

Arctic Science, 2023
The development of indicators as tools for ecosystem monitoring is a key step in the management of marine protected areas (MPAs). This study uses previously developed sex-specific body condition indices, blubber thickness, and girth, to assess temporal ...

Early stages of tooth development in the harbor porpoise Phocoena phocoena

The Anatomical Record, EarlyView.
Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

Visibility of St Lawrence belugas to aerial photography, estimated by direct observation

NAMMCO Scientific Publications, 2002
The depleted population of belugas (Delphinapterus leucas) inhabiting the St Lawrence estuary, Canada, was monitored by periodic photographic aerial surveys. In order to correct counts made on aerial survey film and to obtain an estimate of the true size

Investigating the relationship between the skin microbiome and flame retardant exposure of the endangered St. Lawrence Estuary beluga

Frontiers in Environmental Science, 2022
The endangered beluga (Delphinapterus leucas) population in the St. Lawrence Estuary (SLE) in eastern Canada, the largest estuary in the world, is declining.

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.

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 ...

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 ...
