21. Responses of boreal forest understory plant communities to climate and forestry
Sammanfattning : A warming climate is altering species distributions and community compositions. To understand and predict changes in species distributions to climate change, we often use species occurrences together with large-scale regional climate data. This can be problematic for several reasons. LÄS MER
22. Exploring climate impacts of timber buildings : The effects from including non-traditional aspects in life cycle impact assessment
Sammanfattning : There is an urgency within the building sector to reduce its greenhouse gas emissions and mitigate climate change. An increased proportion of biobased building materials in construction is a potential measure to reduce these emissions. LÄS MER
23. Causal links of past climate change in Coupled Model Intercomparison Project Phase 5 climate models
Sammanfattning : The climate system is influenced by various external forcings (e.g. volcanic forcing, solar forcing and change of greenhouse gas concentrations) and its own internal climate variability. LÄS MER
24. Carbon exchange in boreal ecosystems: upscaling and the impacts of natural disturbances
Sammanfattning : Boreal forests and peatlands are globally significant carbon stores but they are threatened by rising air temperatures and changes in precipitation regimes and the frequency of natural disturbances. Predicting how the boreal biome will respond to climate change depends on being able to accurately model and upscale the greenhouse gas fluxes between these ecosystems and the atmosphere. LÄS MER
25. Climate Related Impacts on a Lake : From Physics to Biology
Sammanfattning : Climatic variation and change affect the dynamics of organisms and ecosystem processes. This thesis examines phytoplankton as a target variable to trace climatic impacts on Lake Erken (Sweden) with special emphasis on the spring bloom. LÄS MER
