Narwhal abundance in West Greenland (WG) and East Greenland (EG) was estimated from aerial surveys conducted between 2007 and 2019 at their summer grounds. Analyses were completed using Mark Recapture Distance Sampling and Hidden Markov Line Transect

Distribution, migrations, and ecology of the Atlantic and the Okhotsk Sea Populations

Autor: O. V. Shpak, Mads Peter Heide-Jørgensen, R. G. Hansen

Bowhead whales from the East Canada-West Greenland (ECWG) and East Greenland-Svalbard-Barents Sea (EGSB) populations are associated with cold water in the North Atlantic. Here they make highly variable seasonal migrations between coastal areas and of

Arctic top predators are expected to be impacted by increasing temperatures associated with climate change, but the relationship between increasing sea temperatures and population dynamics of Arctic cetaceans remains largely unexplored. Narwhals (Mon

The importance of the North Water polynya in Smith Sound as an overwintering area for marine mammals has been questioned. One way to address the issue is to assess the abundance of selected marine mammals that are present during winter in the North W

The predictable narwhal: satellite tracking shows behavioural similarities between isolated subpopulations

Publikováno v: Journal of Zoology. 297:54-65

Comparison of behavioural similarities between subpopulations of species that have been isolated for a long time is important for understanding the general ecology of species that are under pressure from large-scale changes in habitats. Narwhals (Mon
