11. Trophic ecology of meiofauna : Response to sedimentation of phytoplankton blooms in the Baltic Sea
Abstract : 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. READ MORE

12. Baltic cod predation: mechanisms, impact on prey, implications for fisheries
Abstract : Trophic interactions are fundamental in the functioning of ecosystems. Predator-prey interactions between cod (Gadus morhua), herring (Clupea harengus) and sprat (Sprattus sprattus) in the Baltic Sea are typical examples of strong trophic interactions with consequences on the structure of this ecosystem.

13. Lipids in common carp (Cyprinus carpio) and effects on human health
Abstract : There is evidence that n-3 fatty acids (FA), especially EPA and DHA, are beneficial for human health. This thesis examined factors influencing FA composition in common carp flesh, sought to develop a procedure for long-term sustainable culture of common carp with improved muscle lipid quality (omega 3 carp) and studied the health benefits of eating such carp in the secondary prevention of cardiovascular disease.

14. Processes and factors governing benthic community dynamics—environmental change in the Baltic Sea
Abstract : As drivers of biogeochemical cycles and nutrient recycling, such as carbon turnover, the microbial community is essential in sustaining functioning ecosystems. Together with the metazoan community, the microbial community constitute the majority of all life in the benthos. READ MORE

15. Early Life History of the cold-water coral Lophelia pertusa - with implications for dispersal
Abstract : For sessile marine invertebrates the pelagic larval stage is the only means for dispersal, and thus govern population connectivity and maintenance of genetic diversity. It is also a kind of life insurance, i.e. it reduces the risk of extinctions. READ MORE
