1. Linking plant population dynamics to the local environment and forest succession
Abstract : Linking environmental variation to population dynamics is necessary to understand and predict how the environment influences species abundances and distributions. I used demographic, environmental and trait data of forest herbs to study effects of spatial variation in environmental factors on populations as well as environmental change in terms of effects of forest succession on field layer plants.

2. Reproductive strategies and liming responses in forest field-layer flora
Abstract : 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. READ MORE

3. Responses of boreal forest understory plant communities to climate and forestry
Abstract : A warming climate is altering species distributions and community compositions. To understand and predict changes in species distributions to climate change, we often use species occurrences together with large-scale regional climate data. This can be problematic for several reasons. READ MORE

4. Plant Population Dynamics of Dodonaea angustifolia and Olea europaea ssp. cuspidata in Dry Afromontane Forests of Ethiopia
Abstract : Human disturbance has led to excessive deforestation and to a very limited forest cover in the Afromontane zone of Ethiopia, which forms a large part of the country. Thus urgent conservation measures are required to ameliorate the situation. 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.
