DOI: 10.1002/ece3.11034
Abstract: Abstract Algal bioindicators, such as diatoms, often show subdued responses to eutrophication in Arctic lakes because climate‐related changes (e.g., ice cover) tend to be the overriding factors influencing assemblage composition. Here, we examined how sub‐Arctic… read more here.

DOI: 10.1002/rra.4358
Abstract: Initial observations of egg mortality downstream of a hydroelectric facility on the Yellowknife River in the Northwest Territories prompted the investigation of habitat use by adfluvial lake trout (Salvelinus namaycush), lake whitefish (Coregonus clupeaformis), and… read more here.

DOI: 10.1007/s00300-018-2390-6
Abstract: Increasing glacial discharge may influence future recruitment patterns and growth rates of marine benthos in glacial fjords as changes in surface-water temperature and salinity as well as an increase in ice-scouring events. We deployed settling… read more here.

The hemiparasitic angiosperm Bartsia alpina has the potential to accelerate decomposition in sub-arctic communities

DOI: 10.1007/s004420100780
Abstract: We investigated the hypothesis that hemiparasites accelerate nutrient cycling in nutrient-poor communities. Hemiparasites concentrate nutrients in their leaves, thus potentially producing high quality litter that releases nutrients that would otherwise remain in host tissues or… read more here.

Mediation of arsenic mobility by organic matter in mining-impacted sediment from sub‐Arctic lakes: implications for environmental monitoring in a warming climate
Sign Up to like & getrecommendations! Published in 2022 at "Environmental Earth Sciences"
DOI: 10.1007/s12665-022-10213-2
Abstract: Arsenic (As) is commonly sequestered at the sediment–water interface (SWI) in mining-impacted lakes through adsorption and/or co-precipitation with authigenic iron (Fe)-(oxy)hydroxides or sulfides. The results of this study demonstrate that the accumulation of organic matter… read more here.

DOI: 10.1016/j.chemosphere.2018.06.101
Abstract: The seafloor is recognized as one of the major sinks for microplastics (MPs). However, to date there have been no studies reported the MP contamination in benthic organisms from the Arctic and sub-Arctic regions. Therefore,… read more here.

DOI: 10.1111/1365-2435.12703
Abstract: Summary Winter is a period of dormancy for plants of cold environments. However, winter climate is changing, leading to an increasing frequency of stochastic warm periods (winter warming events) and concomitant reductions in snow cover.… read more here.

DOI: 10.1111/gcb.16554
Abstract: Climate warming is leading to permafrost thaw in northern peatlands, and current predictions suggest that thawing will drive greater surface wetness and an increase in methane emissions. Hydrology largely drives peatland vegetation composition, which is… read more here.
