1. Herbivory and plant community structure in a subarctic altitudinal gradient
Abstract : The object of this thesis was to study plant community structure, especially in relation to vertebrate herbivory, in an altitudinal gradient in the Fennoscandian mountain chain.A sowing experiment in a high alpine Ranunculus glacialis population showed that seeds germinated better in cleared microsites than under established individuals.

2. Plant Species Composition and Diversity in Cliff and Mountain Ecosystems
Abstract : Ecosystems today are under increasing pressure from a rapidly changing climate, changes in land-use, habitat fragmentation and degradation and increasing anthropogenic disturbance. Studying drivers of biodiversity patterns is of increasing importance for understanding the dynamics of communities and their reactions and adaptation to changes in the future. READ MORE

3. Volatile mediated plant-plant communication in cultivar mixtures : from plant to aphid responses
Abstract : Modern agriculture is characterized by simplified cropping systems, associated with negative effects on environment, biodiversity and biological control potential. Cultivar mixtures are often presented as a more efficient and sustainable alternative due to additive effects of cultivar properties and pest reduction, but previous studies have provided equivocal results for this claim.

4. Linking root traits and plant-soil feedbacks to environmental change in the sub-arctic tundra
Abstract : Plant community assembly processes shape the composition and abundances of species, and encompass functional traits and resource acquisition strategy of species, biotic interactions and abiotic filtering. Hence, an understanding of these complex processes requires disentangling the effects of multiple factors influencing plant community assembly. READ MORE

5. Secondary succession in tropical dry forests : drivers and mechanisms of forest regeneration
Abstract : Secondary succession is a complex process involving numerous factors acting across scales. Understanding secondary succession in tropical dry forests is important for the conservation and restoration of this highly threatened biome. READ MORE
