3. The impact of permafrost degradation on methane fluxes : a field study in Abisko
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : All over the arctic and sub-arctic region global warming is affecting permafrost. When permafrost thaws, organic material becomes available for decomposition, hence an increase of greenhouse gas emissions to the atmosphere. In the northernmost of Sweden, on a mire close to Abisko, a snow manipulation project is ongoing. READ MORE

4. Climate change effects on freezing damage in three subarctic bryophytes : A snow manipulation field experiment in a tundra ecosystem in Abisko, Sweden
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Climate change is expected to have a large impact on northern ecosystems. Increased temperatures and altered precipitation and snow cover patterns will have a great impact on subarctic tundra. Bryophytes form an important component of tundra ecosystems because of their high abundance and their importance in many ecological processes. READ MORE
