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

Some thoughts on estimating change to Arctic cod populations from hypothetical oil spills in the eastern Alaska Beaufort Sea

Arctic Science, 2017
We describe a fecundity-hindcast model that incorporates Arctic cod (Boreogadus saida) acute toxicity data, field studies of Arctic cod larval distribution and abundance, natural mortality estimates for Arctic cod eggs and larvae, and an oil spill fate ...

Impacts of the Changing Ocean-Sea Ice System on the Key Forage Fish Arctic Cod (Boreogadus Saida) and Subsistence Fisheries in the Western Canadian Arctic—Evaluating Linked Climate, Ecosystem and Economic (CEE) Models

Frontiers in Marine Science, 2019
This study synthesizes results from observations, laboratory experiments and models to showcase how the integration of scientific methods and indigenous knowledge can improve our understanding of (a) past and projected changes in environmental conditions

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

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.

Growth of wild and domesticated Atlantic cod Gadus morhua reared under semi-commercial conditions

Aquaculture Environment Interactions, 2018
Genetic interactions between farmed escapees and wild fish represent a challenge to environmentally sustainable aquaculture. Breeding programs for Atlantic cod Gadus morhua have been initiated; however, the genetic response to selection, and therefore ...

Decline and northward shift in Arctic cod distribution associated with the changing climate around Greenland

Arctic Science
Arctic cod (Boreogadus saida Lepechin, 1774) is a key species in Arctic marine ecosystems, acting as a dominant mid-trophic link that transfers up to 75% of energy to higher trophic levels. It is therefore central to cultural identity, ecosystem function,

Seasonal shifts in feeding patterns: Individual and population realized specialization in a high Arctic fish

Ecology and Evolution, 2019
Species with a broad and flexible diet may be at an advantage in a rapidly changing environment such as in today's Arctic ecosystems. Polar cod (Boreogadus saida), an abundant and ecologically important circumpolar Arctic fish, is often described as a ...

Species richness of scaled Chrysophytes in arctic waters in the Tiksi Region (Yakutia, Russia)

Acta Biologica Sibirica, 2022
Searching for regularities in the species composition and diversity of scaled chrysophytes is crucial for monitoring Arctic waters within the concept of global climate change since these organisms are good indicators of environmental changes ...
