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.

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

Genome Biology
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

Drivers of population dynamics and juvenile mortality in Northwest Atlantic harp seals. [PDF]

Ecol Appl
Abstract Human‐induced threats to terrestrial and marine wildlife are on the rise, and while some species face a single major threat, others face multiple concurrent threats. Harp seals, an abundant pinniped in the North Atlantic that was historically depleted by human harvest, are one such species. Although commercial and subsistence harvests remain a

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

Hepatic Transcriptomic Responsiveness of Polar Cod, Boreogadus saida, to Ocean Acidification and Warming

Fishes
Background: This study was part of a larger comprehensive project (BIOACID) addressing the physiological resilience of Polar cod, Boreogadus saida, to ocean acidification and global warming and aimed to unravel underlying molecular mechanisms of the ...

Developmental Patterns of Hepatic Peroxisome Proliferator-Activated Receptor (PPAR) Expression in Xenopus laevis and Response to Pharmaceutical Agonists During Metamorphic Climax. [PDF]

J Exp Zool A Ecol Integr Physiol
ABSTRACT Peroxisome proliferator‐activated receptors (PPAR) are master transcriptional regulators that maintain metabolic homeostasis in vertebrates. Amphibians are often exposed to endocrine disrupting compounds (EDCs) that could dysregulate lipid metabolism.

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. Polar cod is considered a key species in the Arctic ecosystem.

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.

Sounds of Arctic cod (Boreogadus saida) in captivity: A preliminary description [PDF]

The Journal of the Acoustical Society of America, 2018
Sounds produced by Arctic cod were recorded for the first time and suggest passive acoustic monitoring (PAM) can be an effective additional tool for the study and management of the species. Each of the 38 calls detected in three different aquatic facilities consisted of a single grunt with 6 to 12 pulses and a mean duration of 289 ms.

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
