Rapid genome modifications including chromosomal fusions and large-scale inversions are key features in Arctic codfish species [PDF]
Background 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

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

Fisheries change spawning ground distribution in northeast Arctic cod [PDF]
Prior to the 1920s, the northeast Arctic (NA) cod were caught at spawning grounds ranging from the southernmost to the northernmost parts of the Norwegian coast, but have for the last 50 yr mainly been caught around the Lofoten archipelago and northwards.

The Northeast Greenland Shelf as a Potential Habitat for the Northeast Arctic Cod [PDF]
Observations (1978–1991) of distributions of pelagic juvenile Northeast Arctic cod (Gadus morhua L.) show that up to 1/3 of the year class are dispersed off the continental shelf and into the deep Norwegian Sea while on the way from the spring-spawning areas along the Norwegian coast to the autumn-settlement areas in the Barents Sea.

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]
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.

Northeast arctic cod stock and fishery dynamics
Northeast arctic cod stock is one of a most valuable target of fisheries in the Barents Sea. The catches of cod for the period 1960-2014 are widely changed.

Exploration of short-term predictions and long-term projections of Barents Sea cod biomass using statistical methods on data from dynamical models. [PDF]
This study aims to explore how well simple statistical modeling can generate short-term predictions and long-term projections of the total biomass of the Northeast Arctic stock of Atlantic cod (Gadus Morhua) inhabiting the Barents Sea.

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 ...
