Human-wildlife problems often arise when predators kill livestock. This can develop into serious conflicts between traditional pastoralists and other stakeholders, such as government officials and conservationists. In the Yamal Peninsula (Russia), nearly half of the indigenous Nenets people are reindeer herders. They have recently faced many challenges, such as high mortality of reindeer from pasture ...

Studies of the effects of variation in resource availability are important for understanding the ecology of high-latitude mammals. This paper examines the potential of dental evidence (tooth wear and breakage) as a proxy for diet and food choice in Vulpes lagopus, the Arctic fox. It presents a preliminary study of dental microwear, gross wear score, and tooth breakage in a sample (n = 78 individuals) ...

The Bering Land Bridge (BLB) last connected Eurasia and North America during the Late Pleistocene. Although the BLB would have enabled transfers of terrestrial biota in both directions, it also acted as an ecological filter whose permeability varied considerably over time. Here we explore the possible impacts of this ecological corridor on genetic diversity within, and connectivity among, populations ...

Glacial meltwaters export substantial quantities of dissolved and dissolvable amorphous silicon (DSi and ASi), providing an essential nutrient for downstream diatoms. Evidence suggests that glacially exported DSi is isotopically light compared to DSi in non-glaciated rivers. However, the isotopic fractionation mechanisms are not well constrained, indicating an important gap in our understanding ...

Renewable energy technologies are becoming widely integrated into energy generation systems around the world. While the majority of such technologies are integrated at a large scale in the form of wind and solar farms, there is a need for their incorporation into the built environment. A university campus is an ideal place for testing and understanding how renewable energy technologies can be ...

A comparative study of lipid profile of the daubed shanny <i>Leptoclinus maculatus</i> postlarvae from fjords of different domains (arctic-boreal Kongsfjord and high-arctic Rjipfjord) of Svalbard Archipelago waters in summer was performed. A more efficient accumulation of lipids in the fishes from Kongsfjord compared to Rjipfjord due to triacylglycerols and wax esters was established. These differences ...

The COVID-19 pandemic forced universities to engage in a transformation regarding how education is provided. The pandemic led to education being pushed in a new direction regarding digital practices. This paper discusses the implications related to this transformation by asking the following research question: After being subjected to the imposed and extensive use of online education due to the ...

Self-injurious thoughts (SITs) fluctuate considerably from moment to moment. As such, “static” and temporally stable predictors (e.g., demographic variables, prior history) are suboptimal in predicting imminent SITs. This concern is particularly true for “online” cognitive abilities, which are important for understanding SITs, but are typically measured using tests selected for temporal stability. ...

Background: Migrants in Norway bear a higher burden of COVID-19 infections and hospitalization as compared to non-migrants. The aim of our study was to understand how migrants perceive their own health risk, how they access information regarding the preventive measures, the degree of trust in this information, in the Norwegian authorities and the news media, and migrants’ adherence to authorities’ ...

Background - Systematic training in colonoscopy is highly recommended; however, we have limited knowledge of the effects of “training-the-colonoscopy-trainer” (TCT) courses. Using a national quality register on colonoscopy performance, we aimed to evaluate the effects of TCT participation on defined quality indicators.<p> <p>Methods - This observational study compared quality indicators (pain, ...
