11. 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

12. Vegetation changes on Swedish mires : Effects of raised temperature and increased nitrogen and sulphur influx
Abstract : Since the start of the industrialisation, the deposition of nitrogen and sulphur and the atmospheric concentrations of greenhouse gases have increased. The main objectives of this study were to find how these changes in climate and deposition can change the vegetation of mire ecosystems and the growth of Sphagnumspecies. READ MORE

13. Toxicity of Inorganic Aluminium in Humic Streams
Abstract : Aluminium (Al) has been recognised as a main toxic factor alongside pH in acidified water ecosystems. The toxic effect of Al has been attributed to inorganic Al (Ali), though there are few in situ studies in ambient humic waters which are the focus of this thesis. READ MORE
