6. Aquatic vegetation in coastal ecosystems : The role of biotic interactions and environmental change for ecosystem functions and resilience in the Baltic Sea
Sammanfattning : Coastal ecosystems are among the most productive on Earth but subjected to many human pressures. In shallow coastal areas, aquatic vegetation constitutes foundation species that sustain secondary production and act as a nutrient filter, which may buffer human impacts. LÄS MER
7. Trophic ecology of meiofauna : Response to sedimentation of phytoplankton blooms in the Baltic Sea
Sammanfattning : Marine soft sediments are the second largest habitat on Earth. How animal communities in this habitat are structured is a central issue in marine ecology. Food is an important limiting factor for many benthic populations, and settling organic matter from phytoplankton blooms is of vital importance to them. LÄS MER
8. Neonatal Mortality in Vietnam : Challenges and Effects of a Community-Based Participatory Intervention
Sammanfattning : Globally neonatal mortality accounts for 40% of under-five deaths. Participatory interventions where the local problems are addressed have been successful in some settings. LÄS MER
9. Pollinators, Enemies, Drought, and the Evolution of Reproductive Traits in Primula farinosa
Sammanfattning : In this thesis, I combined comparative and experimental approaches to examine selection on reproductive traits and population differentiation in the insect-pollinated, self-incompatible, perennial herb Primula farinosa. More specifically, I (1) determined whether the effects of floral display and interactions with pollinators and seed predators, and plant reproductive success were frequency-dependent and affected by surrounding vegetation context, (2) examined the consequences of intermittent drought years on population dynamics using numerical simulations based on demographic data collected over seven years, (3) analyzed among-population differentiation in flowering phenology and reproductive allocation, and its relationship to soil-depth at the site of origin.

10. Early Involvement of Industrial Designers in Product Development: Exploring Motives and Challenges
Sammanfattning : The ability to develop and market products that customers value determines a firm’s competitiveness, and product development that aims at competitive advantage must addressdevelopment efficiency in a conscious way. From a strategic point of view, improvements in the early phases of product development, before a development project is launched, areemphasized, and there is a need to study the best way to organize front end teams, and what personal qualities are likely to facilitate front end performance.
