  1. 1. Satellite signal attenuation due to atmospheric influences in northern Sweden

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Adrian Stigsson; [2024]
    Nyckelord :;

    Sammanfattning : Earth-space traversing electromagnetic waves become attenuated as they propagate through the atmosphere. The sources of attenuation are weather phenomena in the Troposphere, and scintillation and absorption in the Ionosphere. LÄS MER

  3. 2. The bzzzt of frirends. Interspecific competition in Arctic plants for pollination services.

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Malin Olsson; [2023-06-27]
    Nyckelord :the Arctic; pollinator networks; competition; autonomous selfing; Arktis; pollinationsnätverk; konkurrens; autonom självpollinering;

    Sammanfattning : The Arctic has a harsh environment that is challenging for the flora and fauna that inhabits the region. The ruling abiotic factors of the region results is a low species richness that creates a potential challenge for the region’s plant species. LÄS MER

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

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Kaavya Venkateswaran; [2023]
    Nyckelord :comparative genomics; microbial ecology; bioinformatics; carbon fixation; pangenomics;

    Sammanfattning : 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

  5. 4. 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 media

    Författare :Jacob Rice; [2023]
    Nyckelord :Russia; Environment; Critical Discourse Studies; Norilsk;

    Sammanfattning : 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.

  7. 5. Legacy effects of temperature alterations on microbial resistance and resilience to drying and rewetting

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Franklin Lee Harris; [2023]
    Nyckelord :microbial ecology; soil; carbon dynamics; high latitudes; climate change; moisture stress; isotopes; respiration; trait based ecology; soil microbes; Environmental Changes in High Latitudes EnCHIL ; Earth and Environmental Sciences; Biology and Life Sciences;

    Sammanfattning : With warming in soils due to climate change, a series of secondary factors arise, which have multifaceted effects on soil microbial communities. Of these, alterations to soil moisture are among the most crucial to understanding how microbial functions will change in the face of climate change. LÄS MER
