Mitochondrial acclimation potential to ocean acidification and warming of Polar cod (Boreogadus saida) and Atlantic cod (Gadus morhua) [PDF]

Frontiers in Zoology, 2017
Background Ocean acidification and warming are happening fast in the Arctic but little is known about the effects of ocean acidification and warming on the physiological performance and survival of Arctic fish.

Plastic ingestion by juvenile polar cod (Boreogadus saida) in the Arctic Ocean. [PDF]

Polar Biol, 2018
One of the recently recognised stressors in Arctic ecosystems concerns plastic litter. In this study, juvenile polar cod (Boreogadus saida) were investigated for the presence of plastics in their stomachs.

The physiological response of the Arctic key species Polar cod, Boreogadus saida, to hypoxia in a warming ocean: critical oxygen levels and swimming performance [PDF]

BMC Zoology
Global warming has already caused a loss of nearly 50% Arctic sea-ice coverage since the 1980s. This sea-ice loss strengthens summer stratification of the ocean’s water column and, consequently, hypoxic zones may form in the deep-water layers.

Climate change impacts on ocean light in Arctic ecosystems [PDF]

Nature Communications
Climate change is causing major sea ice losses, leading to increased light availability across polar marine ecosystems, however the consequences are largely unknown.

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

Distribution and habitat preference of polar cod (Boreogadus saida) in the Bering and Chukchi Seas inferred from species-specific detection of environmental DNA

Frontiers in Marine Science, 2023
Ongoing warming and sea-ice reductions in the Arctic can seriously impact cold-water species, such as polar cod (Boreogadus saida), necessitating biomonitoring to reveal the ecological consequences. Recent methodological advancements in environmental DNA

Arctic cod (Boreogadus saida) in fjord and glacial habitats: a collaborative study with Uummannap Kangerlua fishers

Arctic Science, 2023
Arctic cod (Boreogadus saida) (Lepechin, 1774) is often found in front of glaciers, which is the least studied of the species’ habitats. Uummannap Kangerlua and Sullorsuaq in West Greenland provide a unique opportunity to study Arctic cod in the glacial ...

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.

Forecasted Shifts in Thermal Habitat for Cod Species in the Northwest Atlantic and Eastern Canadian Arctic

Frontiers in Marine Science, 2021
Climate change will alter ecosystems and impose hardships on marine resource users as fish assemblages redistribute to habitats that meet their physiological requirements.
