  1. 21. Applying LPJ-GUESS on the Arctic: A model evaluation and benchmarking study

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Margot Jeanne Knapen; [2023]
    Keywords : Physical Geography and Ecosystem Analysis; LPJ-GUESS; Arctic; FLUXNET; Gross Primary Productivity; Ecosystem Respiration; Permafrost; Active Layer Thickness; Snow Depth; Earth and Environmental Sciences;

    Abstract : 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. READ MORE

  3. 22. Diet of Arctic char and brown trout in Northern Sweden : potential effects of burbot and lake area

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Sebastian Dagman; [2023]
    Keywords : arctic char; brown trout; diet; stomach content; salmonids; burbot;

    Abstract : 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. READ MORE

  4. 23. Comparative genomics of Central Arctic Ocean microbiota for observation of Alternative Carbon Fixation Pathways

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Kaavya Venkateswaran; [2023]
    Keywords : comparative genomics; microbial ecology; bioinformatics; carbon fixation; pangenomics;

    Abstract : 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. READ MORE

  5. 24. Agenda-Setting in the Arctic : Critical Discourse Studies in the Case of the Norilsk Oil Spill

    University essay from Uppsala universitet/Institutet för Rysslands- och Eurasienstudier; Uppsala universitet/Institutionen för informatik och media

    Author : Jacob Rice; [2023]
    Keywords : Russia; Environment; Critical Discourse Studies; Norilsk;

    Abstract : 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.

  6. 25. Plant community responses to 15 years of nitrogen and phosphorus fertilization along an elevational gradient in the subarctic tundra

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Gaya Ten Kate; [2023]
    Keywords : arctic tundra; climate change; fertilization; nitrogen; phosphorus; plant community composition; species richness; Simpson’s diversity; Shannon-Wiener diversity; elevational gradient;

    Abstract : 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. READ MORE
