6. Iron and aluminium speciation in Swedish freshwaters : Implications for geochemical modelling
Abstract : Speciation governs transport and toxicity of trace metals and is important to monitor in natural waters. Geochemical models that predict speciation are valuable tools for monitoring. They can be used for risk assessments and future scenarios such as termination of liming. READ MORE

7. Bark lesions and sensitivity to frost in beech and Norway spruce
Abstract : Strong temperature fluctuations and pathogen attacks can cause bark lesions, visible signs of wounds in the phloem and cambium. Pathogenic insects and fungi are able to invade lesions that have not healed, further increasing the damage. READ MORE

8. Plant responses after drainage and restoration in rich fens
Abstract : Rich fens are an important, but threatened, habitat type in the boreal landscape. In this thesis I have examined responses of rich fen vascular plants and bryophytes after drainage and restoration.The effects of drainage on the rich fen flora were observed in a long time study and the responses were rapid and drastic.

10. Nitrification and Nitrifying Bacterial Communities in Coniferous Forest Soils : Effects of Liming and Clear-Cutting
Abstract : 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. READ MORE
