Report of the NAMMCO-ICES Workshop on Seal Modelling (WKSEALS 2020)

NAMMCO Scientific Publications, 2021
To support sustainable management of apex predator populations, it is important to estimate population size and understand the drivers of population trends to anticipate the consequences of human decisions. Robust population models are needed, which must

Sharing Is Caring?—Pathogens and Pathogen‐Specific Antibodies in Arctic Endemic Seal Species and the Newly Sympatric Harbor Seals in Kongsfjorden, Svalbard

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Climate change associated transformations of Arctic marine ecosystems are having detrimental impacts on Arctic endemic marine mammals. However, warming conditions are providing new habitats for temperate marine mammals, some of which are expanding into Arctic regions, posing a threat of novel pathogen introduction and disease transmission.

Sources of Pre‐ and Postnatal Maternal Energy Allocation to Offspring in a Long‐Lived, Capital Breeder: The Grey Seal (Halichoerus grypus)

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Few studies have simultaneously assessed multiple sources of variation in maternal energy allocation and how allocation might vary over a female's lifetime. We used 20 years of cross‐sectional and longitudinal data on 222 known‐age grey seals, which was collected as part of long‐term monitoring programme of grey seals that breed on Sable Island ...

Climate Change, Local Harvests and Marine Contamination: A Perspective on Cetacean Populations and Coastal Whaling Communities

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Cetaceans are indicators of ocean health, influence marine ecosystem dynamics and hold socio‐economic importance for coastal whaling communities. Yet whale–whaler relationships remain poorly understood and are increasingly compromised under the triple planetary crisis of climate change, biodiversity loss and pollution. Here, we briefly outline

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

Predators and scavengers: Polar bears as marine carrion providers

Oikos, Volume 2026, Issue 1, January 2026.
Scavenging is a foraging strategy widely used across the animal kingdom and apex predators provide a large amount of energy in a food web by provisioning carrion. In the harsh environmental conditions of the Arctic, apex predators such as polar bears Ursus maritimus can provide scavenging opportunities for many species. Carrion can act as a buffer when

Introducing FAMM: An Open‐Access Database of Fossil Arctic Marine Mammals

Global Ecology and Biogeography, Volume 34, Issue 9, September 2025.
ABSTRACT Motivation The Arctic is currently experiencing the strongest effects of climate change on Earth. These effects, including sea ice loss, are already modifying the ecologies of the 11 species of marine mammals found in the Arctic year‐round.
