Drivers of population dynamics and juvenile mortality in Northwest Atlantic harp seals

Ecological Applications, Volume 36, Issue 1, Page 1-25, January 2026.
Abstract Human‐induced threats to terrestrial and marine wildlife are on the rise, and while some species face a single major threat, others face multiple concurrent threats. Harp seals, an abundant pinniped in the North Atlantic that was historically depleted by human harvest, are one such species. Although commercial and subsistence harvests remain a

Subsistence harvest of ringed, bearded, spotted, and ribbon seals in Alaska is sustainable

Endangered Species Research, 2019
In 2012, climate-warming related decreases in sea ice led to listings of ringed Pusa hispida and bearded seals Erignathus barbatus as threatened under the United States Endangered Species Act (ESA) prior to evidence of population declines.

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

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

Do Marine Mammals Diversify More Slowly Than Non‐Marine Mammals?

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Species richness is generally lower in marine than in terrestrial ecosystems, but the reasons behind this disparity remain unclear. This study examines whether marine mammals diversify at a slower pace than their non‐marine counterparts, aiming to shed light on the factors explaining potential diversification differences among them ...

Ringed Seal (Pusa hispida) Abundance in Isfjorden, Svalbard, After 20‐Years of Climate Change and a Concomitant Survey Hiatus

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Ringed seals (Pusa hispida) in Svalbard, Norway, are suspected to be declining due to a significant reduction in land‐fast sea ice, which serves as an essential breeding habitat, but were last surveyed in 2002. We address this data gap by conducting Uncrewed Aerial Systems (UAS) aerial surveys throughout Isfjorden (including adjacent small ...

Are liver and renal lesions in East Greenland polar bears (Ursus maritimus) associated with high mercury levels?

Environmental Health, 2007
Background In the Arctic, polar bears (Ursus maritimus) bio-accumulate mercury as they prey on polluted ringed seals (Phoca hispida) and bearded seals (Erignathus barbatus).
