1. The role of allelopathy in microbial food webs
Abstract : Phytoplankton produce allelochemicals; excreted chemical substances that are affecting other microorganisms in their direct environment.In my thesis, I investigated strain specific variability in the expression of allelochemicals of the harmful flagellate Prymnesium parvum, that is euryhaline but mainly bloom forming in brackish water.

2. Sample preparation and analysis of metabolites from plants in the families of Cyperaceae, Poaceae and Apiaceae
Abstract : An important aspect of understanding how plants effect their environmentis the study of volatile compounds and how these influence interactions between plants and other living organisms. The study of these secondary metabolites from plants can be used in practical applications, such as behaviour control of insects, and is an important part in the search for novel compounds that can be used to influence the behaviour of disease spreading vectors.

3. Summer cyanobacterial blooms in the Baltic Sea - implications for copepod recruitment
Abstract : During summer, the Baltic Sea is subjected to the world’s largest cyanobacterial blooms. These blooms are linked to eutrophication and raise many questions concerning their effects on the ecosystem. To understand their impacts on the food web dynamics, it is essential to assess growth responses of grazers to these cyanobacteria. READ MORE

4. Ecological implications of the production of toxic substances by fish killing phytoplankton species grown under variable N:P-ratios
Abstract : The influence of different nutrient conditions on the production of toxins was studied in certain fishkilling haptophytes (e.g. Prymnesium parvum and Chrysochromulina polylepis). READ MORE

5. On the ecophysiology of Baltic cyanobacteria focusing on bottom-up factors
Abstract : Cyanobacterial blooms in the Baltic Sea are dominated by diazotrophic cyanobacteria, i.e. Aphanizomenon sp. and Nodularia spumigena. READ MORE
