Dechloranes and chlorinated paraffins in sediments and biota of two subarctic lakes [PDF]

Frontiers in Toxicology
Our understanding of the environmental behavior, bioaccumulation and concentrations of chlorinated paraffins (CPs) and Dechloranes (Dec) in the Arctic environment is still limited, particularly in freshwater ecosystems.

Multi-indicator evidence for habitat use and trophic strategy segregation of two sympatric forms of Arctic char from the Cumberland Sound region of Nunavut, Canada

Arctic Science, 2021
We analyzed Arctic char (Salvelinus alpinus (Linnaeus, 1758)) stable isotope ratios and fatty acid composition from two geographically proximal Nunavut lakes, Qasigiyat and Iqalugaarjuit, to determine if anadromous and resident Arctic char occupied ...

Distinct intestinal microbial communities of two sympatric anadromous Arctic salmonids and the effects of migration and feeding

Arctic Science, 2021
Although intestinal microbial communities from anadromous Arctic char (Salvelinus alpinus (Linnaeus, 1758)) in Kitikmeot, Nunavut, Canada, differ depending on the timing and location of capture, determinants of gut microbiota in other wild Arctic ...

Characterizing cytotoxic and estrogenic activity of Arctic char tissue extracts in primary Arctic char hepatocytes [PDF]

Journal of Toxicology and Environmental Health, Part A, 2017
Contaminants from various anthropogenic activities are detected in the Arctic due to long-range atmospheric transport, ocean currents, and living organisms such as migrating fish or seabirds. Although levels of persistent organic pollutants (POPs) in Arctic fish are generally low, local hot spots of contamination were found in freshwater systems such ...

Characterization of anadromous Arctic char winter habitat and egg incubation areas in collaboration with Inuit fishers

Arctic Science, 2023
In Nunavik, anadromous Arctic char spend more than six months under ice-covered habitats, mainly in lakes. Their winter habitats in this region have been scarcely studied due to the challenging logistics in the Arctic. In this study, we worked with Inuit

The Capelin invasion: evidence for a trophic shift in Arctic Char populations from the Cumberland Sound region, Nunavut, Canada

Arctic Science, 2021
Climate change is having myriad effects on Arctic marine ecosystems and food webs. Anadromous Arctic Char, Salvelinus alpinus (Linnaeus, 1758), feed intensively at sea during summer. In Cumberland Sound, Nunavut, Canada, there has been a recent increased

Annual survival probabilities of anadromous Arctic Char remain high and stable despite interannual differences in sea ice melt date

Arctic Science, 2021
Throughout their range, anadromous Arctic Char (Salvelinus alpinus (Linnaeus, 1758)) support commercial, recreational, and subsistence fisheries that are important economically, socially, and culturally.

Environmental Impacts on Skin Microbiomes of Sympatric High Arctic Salmonids

Fishes, 2023
In the region of King William Island, Nunavut, in the Canadian high Arctic, populations of salmonids including Arctic char (Salvelinus alpinus), cisco (Coregonus autumnalis and C. sardinella) as well as lake whitefish (C.
