Arctic‐breeding black‐legged kittiwakes show individual variation in foraging responses to glacial conditions without consequences for reproductive output

Oikos, Volume 2026, Issue 1, January 2026.
Behavioural plasticity is likely to influence how individuals continue to access resources under rapid climate change. Plasticity will be particularly important at highly dynamic, prey‐rich foraging areas such as upwelling fronts of marine‐terminating glaciers in the high Arctic, where profitability varies significantly across space and time ...

Preparing for the unprecedented - Towards quantitative oil risk assessment in the Arctic marine areas [PDF]

, 2017
The probability of major oil accidents in Arctic seas is increasing alongside with increasing maritime traffic. Hence, there is a growing need to understand the risks posed by oil spills to these unique and sensitive areas. So far these risks have mainly

Fish in Kongsfjorden under the influence of climate warming

Frontiers in Marine Science, 2023
IntroductionKongsfjorden is being impacted by climate warming, which has fostered the increase of abundance of Atlantic fish (e.g. Atlantic cod, Gadus morhua), fish that are non-endemic for Kongsfjorden.

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 ...

Intra‐species differences in impacts of climate change: A case study of the hooded seal (Cystophora cristata)

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract The Arctic is warming nearly four times faster than the global average, but the rate of change is not uniform across the region. Wide‐ranging Arctic species are exposed to variable environmental conditions across their range, but it remains unclear how different climate change regimes are affecting populations within the same species that have

Laboratory rearing of wild Arctic cod Boreogadus saida from egg to adulthood

Journal of Fish Biology, 2016
The techniques and protocols used to successfully capture, transport and breed Arctic cod Boreogadus saida, as well as to rear their larvae through to adulthood are summarized. Breeding B. saida will increase the opportunity to study this fish species, which is a critical part of the Arctic food web.

Diet of the ringed seal (Phoca hispida) in Greenland

NAMMCO Scientific Publications, 1998
Analysis of 454 stomachs of ringed seals (Phoca hispida) collected from the Inuit hunt in six municipalities in West Greenland and 30 alimentary tracts collected by scientists in East Greenland, showed seasonal and regional differences in the diet.

Biogeographic Changes in a High Latitude Marine Fish Community: Short‐Time Reversals in Response to Climate Variation

Diversity and Distributions, Volume 31, Issue 11, November 2025.
ABSTRACT Aim Determine whether changes in fish biogeographic composition and key facets of biodiversity are reversible at short time scales in a high latitude marine ecosystem experiencing ocean warming in the context of a recent short‐term cooling, and an increasing then declining dominant apex predator population. Location Barents Sea. Methods Survey
