  4. 3. Phytoplankton succession and algal nutrient kinetics in eutrophic brackish water environments

    Författare :Lena Tinnberg-Kautsky; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alger växter ;

    Sammanfattning : 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.

  5. 4. Plant Major Intrinsic Proteins - natural variation and evolution

    Författare :Jonas Danielson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MIP; aquaporin; plant; natural variation; evolution; Arabidopsis; Physcomitrella patens; NIP; XIP;

    Sammanfattning : 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.

  7. 5. Ecological effects of pesticides in freshwater model ecosystems

    Författare :Lina Wendt-Rasch; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marine biology; aquatic ecology; limnology; Marinbiologi; Hydrobiology; community; zooplankton; algae; herbicide; insecticide; pesticide mixture; macrophytes; cypermethrin; metsulfuron-methyl; risk assessment; pesticides; microcosms; limnologi; akvatisk ekologi;

    Sammanfattning : 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. LÄS MER
