1. 1. How does nutrients and light affect algal growth in Swedish headwater streams? : A study using nutrient diffusing substrate and natural gradients of light

   Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Jannika Andersson; [2014]
   Nyckelord :: boreal streams; algal productivity; N limitation; nutrient diffusing substrate; incident light;

   Sammanfattning : Gaining knowledge about what factors determine benthic algal biomass and productivity is vital for understanding food webs in aquatic systems, especially in woodland streams with naturally low rates of primary productivity. The aim of this study was to investigate what factors determine algal growth in Swedish headwater streams. LÄS MER

3. 2. The impact of climate change on aquatic systems and phytoplankton communities : A quantitative study of the impacts of altering food-quality on microzooplankton growth rate

   Kandidat-uppsats, Institutionen för ekologi, miljö och botanik

   Författare :Linnéa Joandi; [2013]
   Nyckelord :Climate change; phytoplankton communities; microzooplankton; B. Plicatilis; Euplotus sp.; P-limitation; N-limitation; nutrient replete conditions;

   Sammanfattning : A global increase in atmospheric CO2 and temperature is assumed to affect the marine ecosystems in numerous ways, e.g. by altering ocean circulation patterns and changing nutrient regimes. The changes are expected to impact heavily on both phytoplankton communities as well as the rest of the marine food-web. LÄS MER
