11. 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
12. Seasonal interactions between oaks and insects : evolutionary adaptations and predictions for climate change
Sammanfattning : Many species are expected to advance their phenology in response to global warming. As some interactions are dependent on the interacting species being synchronized in time, it is important to assess whether species shift their phenology in synchrony or not. LÄS MER
13. Mechanical behaviour of hardwoods : effects from cellular and cell wall structures
Sammanfattning : Syftet med den här avhandlingen var att undersöka mekaniska egenskaper hos olika arter av lövträd, och koppla egenskaperna till cell- och cellväggsstrukturen i materialet. Arterna som omfattades av undersökningen var Europeisk asp (Populus tremula), hybridasp (Populus tremula x Populus tremuloides) och ek (Quercus robur). LÄS MER
14. Studies on spatial and temporal distributions of epiphytic lichens
Sammanfattning : Lichens are an important group of organisms in terms of environmental issues, conservation biology and biodiversity, principally due to their sensitivity to changes in their environment. Therefore it is important that we develop our understanding of the factors that affect lichen distribution. LÄS MER
15. Holocene climate change and peatland dynamics in southern Sweden based on tree-ring analysis of subfossil wood from peat deposits
Sammanfattning : Dendrochronological analysis was applied to subfossil remains of Scots pine (Pinus sylvestris L.) buried in South Swedish peat deposits. LÄS MER
