Investigating Harvest and Vessel Traffic Exposure as Drivers of Social Group Characteristics in Canadian Beluga ( Delphinapterus leucas ) Populations

Marine Mammal Science, Volume 41, Issue 4, October 2025.
ABSTRACT Assessing variation in social behaviors of group‐living animals may provide insight into the impacts of population stressors. Using very high resolution (VHR) satellite imagery acquired over 3 years, we compared social group size and composition, as well as spatial and social cohesion in three beluga ( Delphinapterus leucas ) populations that ...

Trophic Structure and the Isotopic Niche Dynamics of the Tasiujaq (Eclipse Sound, Nunavut, Canada) Marine Food Web

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 9, September 2025.
ABSTRACT Rapid warming in the Arctic is causing cumulative impacts on ecosystems, including widespread reduction in sea ice extent, resulting in shifts in primary production, which can have cascading bottom‐up trophic influences on marine food web structure and function. Understanding trophic interactions and the structure of local food webs across the

Use of tusks by narwhals, Monodon monoceros, in foraging, exploratory, and play behavior

Frontiers in Marine Science
Despite the universal fascination with the tusk of the narwhal, the function of this long, spiraled tooth is still debated, primarily because few people have observed how narwhals (Monodon monoceros) use their tusks in the wild.

Distribution and Abundance of the Eastern Canada – West Greenland Bowhead Whale Population Based on the 2013 High Arctic Cetacean Survey

NAMMCO Scientific Publications, 2020
The hunting of bowhead whales (Balaena mysticetus) is an integral part of Inuit culture. An up-to-date abundance estimate of the entire Eastern Canada – West Greenland (EC-WG) bowhead population is necessary to support sustainable management of this ...

Size and trends of the bowhead whale, beluga and narwhal stocks wintering off West Greenland

NAMMCO Scientific Publications, 2002
To assess the size and trends of the abundance of the bowhead whale (Balaena mysticetus), the beluga, or white whale (Delphinapterus leucas), and the narwhal (Monodon monoceros) visual aerial surveys were conducted in West Greenland in March 1998 and ...

Are narwhals critical for the meat supply in East Greenland?

Arctic Science
In East Greenland, the recommendations for the closure of the narwhal (Monodon monoceros) hunt coincide with a pressing demand to continue hunting for meat to supply local communities. By analysing catch statistics and estimating average meat yields, the
