The thick-billed murre (Uria lomvia) in Northwest Greenland (Avanersuaq) relies on Arctic cod (Boreogadus saida) in a changing climate

Arctic Science
Considering seabirds as indicators of environmental change, we compared thick-billed murre (Uria lomvia (Linnaeus, 1758)) adult and chick diet in the North Water polynya region, NW Greenland, during 1997 and 2023.

Arctic cod (Boreogadus saida) hatching in the Hudson Bay system [PDF]

Elementa: Science of the Anthropocene, 2021
Buoyant Arctic cod (Boreogadus saida) eggs are found at the surface or at the ice-water interface in winter. While winter temperatures in saline waters fall below 0°C, the temperature in areas affected by under-ice river plumes is slightly higher.

Reference genome bias in light of species-specific chromosomal reorganization and translocations [PDF]

Genome Biology
Background Whole-genome sequencing efforts, have during the past decade, unveiled the central role of genomic rearrangements—such as chromosomal inversions—in evolutionary processes, including local adaptation in a wide range of taxa. However, employment

Impacts of the Changing Ocean-Sea Ice System on the Key Forage Fish Arctic Cod (Boreogadus Saida) and Subsistence Fisheries in the Western Canadian Arctic—Evaluating Linked Climate, Ecosystem and Economic (CEE) Models

Frontiers in Marine Science, 2019
This study synthesizes results from observations, laboratory experiments and models to showcase how the integration of scientific methods and indigenous knowledge can improve our understanding of (a) past and projected changes in environmental conditions

Black-legged kittiwakes (Rissa tridactyla) readily consume Arctic cod (Boreogadus saida) in the Canadian Arctic: insights from stomach content and stable isotope analyses

Arctic Science
The Arctic is undergoing rapid declines in sea ice and changes in Arctic ecosystems. The diet of one of the Arctic’s most abundant seabirds, the black-legged kittiwake (Rissa tridactyla), has been used as an indicator of ecosystem changes in the European

Susceptibility of polar cod (Boreogadus saida) to a model carcinogen [PDF]

Marine Environmental Research, 2021
Studies that aim to characterise the susceptibility of the ecologically relevant and non-model fish polar cod (Boreogadus saida) to model carcinogens are required. Polar cod were exposed under laboratory conditions for six months to control, 0.03 μg BaP/g fish/week and 0.3 μg BaP/g fish/week dietary benzo(a)pyrene (BaP), a reference carcinogen.

Top-Down and Bottom-Up Processes Jointly Explain Mesopredator Movement and Foraging Ecology. [PDF]

Ecol Lett
This study integrates top‐down (polar bear habitat selection) and bottom‐up (fish distribution) processes to test how mesopredators (ringed seals) balance risk–reward tradeoffs in habitat selection. Ringed seals reduced their space use and foraging time in response to predation risk, yet accepted higher risk when prey diversity was elevated ...

Circumpolar genetic population structure of polar cod, Boreogadus saida

Polar Biology, 2020
Polar cod, Boreogadus saida, is an important part of Arctic and boreal marine ecosystems. Knowledge of polar cod population genetic structuring can provide insight into how the species may respond to environmental change, and allow for establishment of meaningful management units. To examine population genetic structure of B.

Low levels of hybridization between sympatric cold-water-adapted Arctic cod and Polar cod in the Beaufort Sea confirm genetic distinctiveness

Arctic Science, 2022
As marine ecosystems respond to climate change and other stressors, it is necessary to evaluate current and past hybridization events to gain insight on the outcomes and drivers of such events. Ancestral introgression within the gadids has been suggested
