Genomic architecture and population structure of Boreogadus saida from Canadian waters [PDF]
Scientific ReportsThe polar cod, Boreogadus saida, is an abundant and ubiquitous forage fish and a crucial link in Arctic marine trophic dynamics. Our objective was to unravel layers of genomic structure in B.

Gender specific reproductive strategies of an arctic key species (Boreogadus saida) and implications of climate change. [PDF]
PLoS ONE, 2014 The Arctic climate is changing at an unprecedented rate. What consequences this may have on the Arctic marine ecosystem depends to a large degree on how its species will respond both directly to elevated temperatures and more indirectly through ...

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.

Arctic cod (Boreogadus saida, Gadidae) in the Chukchi Sea and adjacent waters
Известия ТИНРО, 2021 Biology, spatial distribution, migrations, and stock dynamics are considered for arctic cod in the Russian sector of the Chukchi Sea and adjacent waters of the northern Bering Sea on the data of trawl surveys conducted by Pacific Res. Inst.

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.

Under-ice observations by trawls and multi-frequency acoustics in the Central Arctic Ocean reveals abundance and composition of pelagic fauna [PDF]
Scientific Reports, 2023 The rapid ongoing changes in the Central Arctic Ocean call for baseline information on the pelagic fauna. However, sampling for motile organisms which easily escape vertically towed nets is challenging.

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

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

Arctic Science, 2021 Climate change is rapidly modifying marine fish assemblages in the Arctic. As fish eggs and larvae have a narrower thermal tolerance than nonreproductive adults, their response to increasing temperatures is likely one of the main drivers of these changes.
