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 ManagementAbstract : 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

7. Legacy effects of temperature alterations on microbial resistance and resilience to drying and rewetting
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : 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

8. Analysis of energy efficient heat and lighting systems in a subarctic greenhouse
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : 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.

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 matematikAbstract : 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

10. Evaluating DInSAR for measuring seasonal elevation dynamics at the Vissátvuopmi palsa mire complex in Northern Sweden
University essay from Göteborgs universitet/Institutionen för geovetenskaperAbstract : 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.
