1. Nutrient Stoichiometry in Benthic Food Webs – Interactions Between Algae, Herbivores and Fish
Sammanfattning : The aim of this thesis was to identify general structuring mechanisms in benthic food webs within the framework of ecological stoichiometry theory. Ecological stoichiometry is defined as the balance of multiple chemical substances in ecological interactions and explicitly considers the combined dynamics of key elements such as carbon (C), nitrogen (N) and phosphorus (P).

2. Effects of inorganic nitrogen and organic carbon on pelagic food webs in boreal lakes
Sammanfattning : Anthropogenic activities are increasing inorganic nitrogen (N) loadings to lakes in the northern hemisphere. In many boreal lakes phytoplankton are N limited, wherefore enhanced N input may affect the productivity of pelagic food webs. LÄS MER
3. Nitrogen Removal in Created Wetlands : Considerations – Challenges – Possibilities
Sammanfattning : Created wetlands in agricultural landscapes deliver a multitude of ecosystem services, one of which is the removal of nitrogen (N) from water to reduce eutrophication. Wetland N removal, primarily through denitrification, is influenced by various factors. LÄS MER
