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.

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 ZoologyGlobal 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.

Rapid genome modifications including chromosomal fusions and large-scale inversions are key features in Arctic codfish species [PDF]
Genome BiologyBackground Genome evolvability involves activation of transposable elements (TEs) that result in novel genomic rearrangements, including translocations, deletions, duplications, as well as larger structural reorganizations, such as chromosomal inversions

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

Subchronic PAH Exposure Impacts Cardiac Electrophysiology of the Polar Fish, Navaga Cod (Eleginus nawaga) [PDF]
ToxicsPolycyclic aromatic hydrocarbons (PAHs) from the water-soluble fraction (WSF) of crude oil are recognized cardiotoxicants in fish; however, all electrophysiological evidence to date derives from acute exposure experiments. This study examined the effects

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.
