3. Phytoplankton succession and algal nutrient kinetics in eutrophic brackish water environments
Abstract : This thesis has been concerned with studying the effects of pollution on aquatic ecosystems with the main emphasis on investigating the phytoplankton succession in the brackish bay of Brunnsviken after sewage diversion.The causes of the observed changes have been investigated through enrichment experiments with phytoplankton in batch cultures and in studies of the nutrient uptake kinetics of Enteromorpha compressa.

4. Plant Major Intrinsic Proteins - natural variation and evolution
Abstract : Major Intrinsic Proteins (MIPs, also called Aquaporins, AQPs) are channel forming membrane proteins. Although initially functionally characterized and named after their water channeling property in human red blood cells, it has become increasingly evident that MIPs are present in all types of organisms and transport a variety of small, uncharged molecules besides water.

Abstract : In this thesis I have investigated the effects of pesticide exposure on the ecosystem level using various types of experimental ecosystems, i.e. microcosms. The direct effect of exposure to cyperemthrin, a pyretroid insecticide, was a rapid decrease of crustancean zooplankton in enclosures in a lake. READ MORE
