  4. 24. 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. 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
