Beluga whale (Delphinapterus leucas) behaviour in the presence of whale-watching vessels

Frontiers in Marine Science, 2023
Beluga whales (Delphinapterus leucas) are social animals that return to the same estuaries each summer season. The Western Hudson Bay belugas in the Churchill River estuary appear to be attracted to boats, resulting in whale-watching being a popular ...

Estimating reproductive and juvenile survival rates when offspring ages are uncertain: A novel multievent mark‐resight model with beluga whale case study

Methods in Ecology and Evolution, 2023
Understanding the survival and reproductive rates of a population is critical to determining its long‐term dynamics and viability. Mark‐resight models are often used to estimate these demographic rates, but estimation of survival and reproductive rates ...

The Electrocardiogram of a Beluga Whale [PDF]

Circulation, 1953
In the course of our study of the comparative anatomy and physiology of the mammalian heart, it became necessary to develop a technic to obtain the electrocardiogram of the largest mammal of all. Because of its availability, the small white Beluga whale in northern waters was the first object of this research, prior to obtaining the record of a large ...

Population dynamics of the threatened Cumberland Sound beluga (Delphinapterus leucas) population

Arctic Science, 2021
Current scientific evidence indicates that the threatened Cumberland Sound beluga whale (Delphinapterus leucas (Pallas, 1776)) population is genetically differentiated and spatially segregated from other beluga whale populations. This population has been

Machine learning models development for accurate multi-months ahead drought forecasting: Case study of the Great Lakes, North America.

PLoS ONE, 2023
The Great Lakes are critical freshwater sources, supporting millions of people, agriculture, and ecosystems. However, climate change has worsened droughts, leading to significant economic and social consequences.

Cementum structure in Beluga whale teeth [PDF]

Acta Biomaterialia, 2017
A large fraction of the volume of Beluga whale (Delphinapterus leucas) teeth consists of cementum, a mineralized tissue which grows throughout the life of the animal and to which the periodontal ligaments attach. Annular growth bands or growth layer groups (GLGs) form within Beluga cementum, and this study investigates GLG structure using X-ray ...

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.
