1. The potential of wetlands for mitigation of eutrophication and brownification
Sammanfattning : Increasing nutrient concentrations (eutrophication) and water color due to dissolved organic matter (brownification) pose continuous threats to freshwater ecosystems worldwide, threatening ecosystem services like drinking water supply. Changing the increasing trends of eutrophication and brownification on our aquatic ecosystems is challenging. LÄS MER
2. Trophic effects on the maintenance of biodiversity in the Fucus zone
Sammanfattning : Ecologically important macroalgae with large thalli and complex structures are threatened worldwide due to anthropogenic activities such as pollution. In the northern Baltic Sea the salinity is very low; the only large algae producing complex structural habitats found there are the fucoid species Fucus radicans and F. vesiculosus. LÄS MER
3. Exposure and effects of naturally produced hydroxylated polybrominated diphenyl ethers in fish : Implications for Baltic Sea wildlife
Sammanfattning : The aim of this thesis was to investigate if naturally produced hydroxylated polybrominated diphenyl ethers (OH-PBDEs) are causing negative health effects for Baltic Sea wildlife. In the laboratory, OH-PBDEs have shown to be potent disrupters of energy metabolism as well as endocrine disruptors and neurotoxins. LÄS MER
4. Filamentous Fungi as a Sustainable Ingredient for Fish Feed
Sammanfattning : Limited feed ingredients hinder aquaculture’s rapid growth. Current unsustainable fish feeding practices use ingredients like fishmeal and soybean meal, which could be directly consumed for as human food. This demands novel alternatives for fish nutrition. LÄS MER
5. Molecular evidence for metazooplankton feeding on filamentous cyanobacteria and picocyanobacteria in the Baltic Sea
Sammanfattning : Interactions between zooplankton and cyanobacteria are complex and system-specific. They play an important role in mediating responses of phytoplankton to changes in nutrient regime and top-down manipulations. LÄS MER
