26. Applying LPJ-GUESS on the Arctic: A model evaluation and benchmarking study
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Warming in the Arctic occurs at a much higher rate than the global average, which has a considerable impact on the Arctic terrestrial carbon cycle. Permafrost thawing can release substantial amounts of carbon, whilst tundra shrubification and tree-line advance, on the other hand, may compensate for this. LÄS MER
27. Diet of Arctic char and brown trout in Northern Sweden : potential effects of burbot and lake area
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : To manage and conserve different fish species, it is important to know what factors affect the presence and performance of the species. Relatively few studies have focused on burbot and how they interact with other species. LÄS MER
28. Comparative genomics of Central Arctic Ocean microbiota for observation of Alternative Carbon Fixation Pathways
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : The Central Arctic Ocean is a repository of rich and diverse biota, whose major portion is one of the most important drivers of global biogeochemical cycles, including carbon cycling. In this study, the functional potential of the microbiota to fix carbon with alternative carbon fixation pathways were investigated along with their chemolithotrophic characteristics. LÄS MER
29. Agenda-Setting in the Arctic : Critical Discourse Studies in the Case of the Norilsk Oil Spill
Master-uppsats, Uppsala universitet/Institutet för Rysslands- och Eurasienstudier; Uppsala universitet/Institutionen för informatik och mediaSammanfattning : This paper examines the existing discourses surrounding environmental issues in Russia using a large oil Spill in Norilsk as a case study. The spill, which occurred in the summer of 2020, is the largest man-made disaster to ever occur in the Arctic, resulting in around 21,000 tons of diesel fuel being spilled into the ground and surrounding waterways.

30. Plant community responses to 15 years of nitrogen and phosphorus fertilization along an elevational gradient in the subarctic tundra
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Climate change in the Arctic has profound effects on tundra vegetation, directly through increasing temperatures and indirectly through changes in plant community composition and nutrient cycling. Fertilization experiments are widely used to study the effects of increased nutrient availability on arctic tundra vegetation. LÄS MER
