1. Carbon Balance Implications of Forest Biomass Production Potential
Sammanfattning : Forests in boreal and temperate forest-ecosystems have importance for carbonbalance since they sequester large amount of atmospheric carbon by uptake ofcarbon-dioxide during photosynthesis, and transfer and store carbon in the forestecosystem. Forest material can be used for bio-fuel purposes and substitute fossilfuels, and supply wood products, which can replace carbon-and-energy-intensivematerials. LÄS MER
2. Regeneration in continuous cover forestry systems
Sammanfattning : The overall aim of the studies underlying this thesis has been to qualify and quantify the regeneration of tree species in a range of typical growing environments of possible Continuous Cover Forestry (CCF) silvicultural systems in boreal forests of northern Sweden. Data presented in Papers I and II show that the light environment did not differ significantly between points at different distances to trees, but it was clearly affected by the stand stem density (SSD).

3. Spatial Variation in Near-Ground Radiation and Low Temperature - Interactions with Forest Vegetation
Sammanfattning : Low temperature has a large impact on the survival and distribution of plants. Interactive effects with high irradiance lead to cold-induced photoinhibition, which may impact on the establishment and growth of tree seedlings. LÄS MER
4. Forestry impact on water quality: a landscape perspective on dissolved organic carbon
Sammanfattning : Dissolved organic carbon (DOC) is a fundamental variable defining boreal stream ecosystems. In this thesis the impact of forestry practices that are commonly performed in the boreal regions of Scandinavia for stream water quality were evaluated. LÄS MER
5. Birds and butterflies at the forest-farmland interface
Sammanfattning : Land-use change is one of the greatest threats to biodiversity. Through intensification of land-use, the agricultural landscape has become more homogenous and a result, many species associated with traditional farmland or other semi-natural open habitats have declined. LÄS MER
