  1. 1. 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

  3. 2. 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

  4. 3. Evaluating DInSAR for measuring seasonal elevation dynamics at the Vissátvuopmi palsa mire complex in Northern Sweden

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :André Farjami; [2022-09-09]
    Nyckelord :;

    Sammanfattning : During recent years the palsa mires of Fennoscandia have reported to be undergoing extensive lateral degradation, and in a warming environment the palsa mires of Sweden among others are threatened to thaw completely by the end of this century. Since subarctic peatlands account for 30% of the global soil organic carbon storage, small degradation changes in these areas globally, can potentially change the greenhouse gas emissions on a worldwide scale.

  5. 4. ARCTIC MYCORRHIZAL INTERACTIONS UNDER CLIMATE CHANGE

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

    Författare :Otto Minas; [2022-07-06]
    Nyckelord :Climate change; Arctic ecology; arbuscular mycorrhiza; graminoids; plant ecology; soil ecology; carbon cycle.;

    Sammanfattning : The Arctic is experiencing climate change at an extreme rate, affecting both the rates of plant growth and nutrient cycling. Due to the changes in temperature, but also in nutrient cycling, with increased nutrient mineralization and decreasing P:N ratio (phosphorus, P and nitrogen, N), the arbuscular mycorrhizal fungi (AM) that are prevalent in warmer soils have shown the potential to increase in the otherwise unfavorable Arctic environment.

  7. 5. An Initial Analysis of Slurry Transportation in Subarctic Environment

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Wilhelm Friberg; [2021]
    Nyckelord :Slurry Transport;

    Sammanfattning : In today’s economy, it is important to have a sustainable business model where as little as possible goes to waste or finding solutions to create something useful out of by-products. Therefore, LKAB are looking to make a large investment into creating an infrastructure of several plants to turn tailings from the production of iron ore into usable products for several industries which LKAB has designated project ReeMAP (Rear Earth Elements and MonoAmmonium Phosphate).
