1. Spring water stress in Scots pine: interaction of snow and soil temperature
Sammanfattning : Water use and net carbon assimilation during spring was examined on Scots pine trees exposed to different soil warming dynamics in the field. Sap flow, needle water potential and net carbon assimilation were measured on trees that were exposed to a wide range of soil temperature regimes caused by manipulating the snow cover on tree-scale soil plots.

2. The significance of soil conditions for sap flow of Scots pine in the boreal environment
Sammanfattning : .... LÄS MER
3. Silviculture of oak for high-quality wood production : effects of thinning on crown size, volume growth and stem quality in even-aged stands of pedunculate oak (Quercus robur L.) in Northern Europe
Sammanfattning : Oak is one of the most valuable noble hardwood species in Europe. The production of high-quality wood is associated with long rotations and high labour costs. LÄS MER
4. The introduction of Pinus contorta in Sweden : implications for forest diversity
Sammanfattning : An increasing demand for forest-based products calls for further development and intensification of forest management. The use of non-native tree species in forestry is a common and expanding silvicultural practice worldwide but the effect of non-native trees on native biodiversity and ecosystem functioning is still poorly understood.

5. Chemical signals in interactions between Hylobius abietis and associated bacteria
Sammanfattning : The pine weevil (Hylobius abietis L.) is one of the two topmost economically important insect pests in Swedish conifer forests. The damage increase in areas were the silvicultural practice is to use clear cuttings were the insects gather and breed. LÄS MER
