11. Forest-stream linkages : Experimental studies of foraging and growth of brown trout (Salmo trutta L)
Abstract : Riparian vegetation along streams and rivers affects the aquatic community in numerous ways and often operates as a link for energy flux between forest and streams. The studies presented in this licentiate thesis focus on light and terrestrial invertebrates, two factors influenced by riparian zone structure, which potentially affect stream ecosystems and thus also brown trout (Salmo trutta).

12. Nutrient Stoichiometry in Benthic Food Webs – Interactions Between Algae, Herbivores and Fish
Abstract : 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).

13. Role of sediment organic matter quality and benthic organisms for the fate of organic contaminants in marine systems
Abstract : Marine sediments constitute important contaminant sources within our environment. Organic matter input to marine sediments changes seasonally in terms of both quantity and quality, and has been profoundly altered in many coastal areas due to eutrophication. READ MORE

14. Lake bathymetry as driver of salmonid population size structure and biomass
Abstract : Most fish species undergo ontogenetic niche shifts from feeding on pelagic zooplankton, to larger benthic invertebrates and in some cases also to fish. These ontogenetic niche shifts have strong impact on the interactions within and between species, with effects on individual growth, population abundance and food web dynamics. READ MORE

15. Environmental occurrence and behaviour of the flame retardant decabromodiphenyl ethane
Abstract : The environmental occurrence and behaviour of the brominated flame retardant (BFR) decabromodiphenyl ethane (dbdpe) has only been studied to a limited extent. It is structurally similar to decabromodiphenyl ether (decaBDE), which makes it conceivable that dbdpe may also become an environmental contaminant of concern. READ MORE
