1. Effects of natural warming and snow on grass phenology and fitness
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Organisms respond to changes in their environment using different strategies. Understanding how species deal with changes expected due to ongoing climate change is important for making accurate predictions about their effect on ecosystems. LÄS MER
2. Effects of climate change on freezing damage in three subarctic bryophyte species
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Climate change is expected to have a strong impact on subarctic ecosystems. Increased temperatures as well as altered precipitation and snow cover patterns are predicted to change species distribution and affect biogeochemical processes in the subarctic tundra. LÄS MER
3. The impact of permafrost degradation on methane fluxes : a field study in Abisko
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : 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. LÄS MER
4. Climate change effects on freezing damage in three subarctic bryophytes : A snow manipulation field experiment in a tundra ecosystem in Abisko, Sweden
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : 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. LÄS MER
5. The potential impact of changing vegetation on thawing permafrost : effects of manipulated vegetation on summer ground temperatures and soil moisture in Abisko, Sweden
Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : The Arctic region has experienced significant warming in the past decades and according to predictions further increases in air temperatures and precipitation will occur during the 21st century. Recent changes in climate have had widespread implications for the permafrost around the Arctic. LÄS MER
