  1. 6. 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

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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Franklin Lee Harris; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 8. Analysis of energy efficient heat and lighting systems in a subarctic greenhouse

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : William Sigvardsson; [2023]
    Keywords : Energy efficiency; Sub-arctic greenhouses; Energy measures; Greenhouse climate control; Greenhouse technology; CFD;

    Abstract : This report studies a subarctic greenhouse located in Nikkala, Sweden called Nikkala handelsträdgård. Through a visit to the greenhouse coupled with the creation of two simulation models this study investigates the differences in energy demand with water-carried and air-carried heating systems, high pressure sodium lights and Light emitting diode lights and insulation in parts of the greenhouse without a active cultivation.

  4. 9. Dynamic simulation and techno-economicevaluation of a seasonally insulated hybridgreenhouse concept for subarctic climates

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Christoffer Alenius; [2023]
    Keywords : ;

    Abstract : The Swedish authority for social protection and preparedness, MSB, believes that the self-sufficiency of the country must be strengthened in order to be prepared for a crisis. Presently, Sweden is only 50% self-sufficientwhich is very low compared to its neighboring countries; and it is worse the further north you go. READ MORE

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

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : André Farjami; [2022-09-09]
    Keywords : ;

    Abstract : 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.
