   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; microphytobenthos; phytoplankton; heterotrophic bacteria; interactions; nutrients; carbon cycling; clearwater lakes; Biologi; Biology; Biologi;

   Sammanfattning : This thesis focuses on the interactions among microbiota in clearwater lakes. Field sampling and field experiments were performed to evaluate interactions among microbiota and the importance of benthic versus pelagic microbiota in terms of biomass and production. In addition, carbon cycling in an oligotrophic clearwater lake was calculated. LÄS MER

3. 2. The Role of Picophytoplankton in Lake Food Webs

   Sammanfattning : Picophytoplankton were inferior competitors for inorganic phosphorus compared to heterotrophic bacteria. This may be due to the source of energy available for the heterotrophs, while cell-size was of minor importance. However, picophytoplankton were superior to large phytoplankton in the competition for nutrients at low concentrations. LÄS MER
