1. Reproductive strategies and liming responses in forest field-layer flora
Sammanfattning : Liming increased species richness, in accordance with the species pool hypothesis, and number of plants of individual species in beech forest field-layer vegetation, by increasing establishment by seedlings and vegetative offspring. Turnover rates also increased, suggesting the explanatory value of the carousel model. LÄS MER

3. Nitrification and Nitrifying Bacterial Communities in Coniferous Forest Soils : Effects of Liming and Clear-Cutting
Sammanfattning : This thesis deals with the effects of liming and clear-cutting on nitrification in hemi-boreal and northern temperate coniferous forest soils. The approach has been to study both the potential nitrification and the community structure of the ammonia-oxidising bacteria, which carry out the first step of autotrophic nitrification. LÄS MER
4. A paleolimnological perspective on liming – implications for defining reference conditions in Swedish lakes
Sammanfattning : Using paleolimnological techniques, I have studied surface-water acidification and the effects of liming in Swedish lakes on a decadal to millennial time-scale. The overall objective was to contribute to the discussion on the fulfilment of goals within the Swedish liming program. LÄS MER
5. Seed production and natural regeneration of beech (Fagus sylvatica L.) in southern Sweden
Sammanfattning : When mature beech forests are harvested, the new regeneration is established by natural regeneration, which is by using the seeds from the old stand to create the new generation. Most often the seed from a single mast year is used preceded by site preparation. LÄS MER
