1. Ecology of juvenile turbot and flounder in the Central Baltic Sea : Implications for recruitment
Abstract : Our understanding of turbot and flounder ecology in the Baltic Sea is insufficient for sound management decisions. This thesis aims to fill some gaps in current knowledge by providing information of the ecology of turbot and flounder within their juvenile habitat, and to relate these findings to issues assumed relevant for recruitment variation.

2. Effects of seed size and habitat on recruitment patterns in grassland and forest plants
Abstract : A trade-off between seed size and seed number is central in seed ecology, and has been suggested to be related to a trade-off between competition and colonization, as well as to a trade-off between stress tolerance and fecundity. Large seeds endure hazards during establishment, such as shading, drought, litter coverage and competition from other plants, better than do small seeds, due to a larger amount of stored resources in the seed.

3. Upholding the coral loop : Resilience, alternative stable states and feedbacks in coral reefs
Abstract : Coral reefs are suffering unprecedented declines in coral cover and species diversity. These changes are often associated with substantial shifts in community structure to new dominant organisms. Ultimately, these “phase shifts” can be persistent and very difficult to return from.

4. On dysregulated inflammation and airway host defense
Abstract : Acute respiratory distress syndrome (ARDS), chronic obstructive pulmonary disease (COPD), and cystic fibrosis (CF) are characterized by dysregulated inflammation of the airways. The increased influx of immune cells and the accumulation of cytokines lead to cell death, tissue destruction and impaired pulmonary function. READ MORE

5. Innate defense mechanisms of the nasal airway
Abstract : Allergic and infectious rhinitis are prevalent conditions that besides a direct morbidity also causes exacerbations of asthma and chronic obstructive pulmonary disease. The immune mechanisms associated with various forms of rhinitis are not fully understood. READ MORE
