16. Vegetation patterns and processes in riparian landscapes
Sammanfattning : The objective of this study was to increase understanding of the processes structuring and controlling the species richness of riparian plant communities. In particular, I examined the unimodal relationship, found in many rivers, between plant species richness and location along the river corridor. LÄS MER
17. Novel biologically active compounds by semisynthesis with fungal metabolites
Sammanfattning : Natural products have been shown to be an important source of novel compounds for the development of new drugs and pesticides. However, many biologically active natural products contain reactive functionalities that make them toxic. LÄS MER
18. Forest restoration using direct seeding of oak – Odor cues from predators as a seed protection strategy against foraging rodents
Sammanfattning : In forest restoration of oak, planting nursery-growth seedlings is related to high operational costs. One cost-efficient alternative is the application of direct seeding. However, acorn removal by rodents is one of the major drawbacks in its implementation. LÄS MER
19. Computational Studies of Photobiological Keto-Enol Reactions and Chromophores
Sammanfattning : This thesis presents computational chemistry studies of keto-enol reactions and chromophores of photobiological signicance.The rst part of the thesis is concerned with two protein-bound chromophores that, depending on the chemical conditions, can exist in a number of dierent ketonic and enolic forms.

20. Genetically Engineered Plants: Improved stress tolerance, growth and facilitated protein purification
Sammanfattning : Heterologous genes were expressed in plants in which the overall goal was to increase the value of the final crop. Various aspects were explored and evaluated, such as improving the stress tolerance, enhancing the availability of oxygen in growing cells and producing rare proteins with increased degrees of purity.
