1. Population biology of the clonal plant Ranunculus lingua
Abstract : The scope of this thesis was to identify, describe and quantify important life-history traits for the pseudoannual aquatic plant Ranunculus lingua in different ecological settings, by comparing populations from geographically marginal vs. central habitats. READ MORE

2. Life-history traits and population differentiation in a clonal plant: implications for establishment, persistence and weediness
Abstract : Clonality is wide-spread among plants, and clonal plants dominate many habitats and include many highly invasive species. Clonal growth incurs both advantages and costs and clonal plants often have reduced sexual reproduction compared to non-clonal plants which could be expected to lower genetic variation and hence evolutionary potential.

3. Physiological integration and morphological plasticity in extensive clonal plants
Abstract : Clonal plants show a large variation in physiological integration, i.e. the translocation of resources among ramets within the clone. READ MORE

4. Life History Strategies in Linnaea borealis
Abstract : About 70% of the plant species in the temperate zone are characterised by clonal growth, clonal species are also in majority in the Arctic and Subarctic where they affect the structure and composition of the vegetation. It is therefore of great importance to increase our knowledge about clonal plants and their growth and life histories. READ MORE

5. Carex humilis - a caespitose clonal plant: ramet demography, ring formation, and community interactions
Abstract : Carex humilis forms rings of densely aggregated ramets in dry grassland vegetation in Central Europe. In the thesis I conclude that ramet demography is important both for analyzing fitness in clonal plants and for understanding how C. humilis rings are formed. I studied the ramet demography of C.
