6. Summer cyanobacterial blooms in the Baltic Sea - implications for copepod recruitment
Sammanfattning : During summer, the Baltic Sea is subjected to the world’s largest cyanobacterial blooms. These blooms are linked to eutrophication and raise many questions concerning their effects on the ecosystem. To understand their impacts on the food web dynamics, it is essential to assess growth responses of grazers to these cyanobacteria. LÄS MER
7. Grazing in Macroalgae Communities of the Baltic Sea
Sammanfattning : Fucus vesiculosus and Fucus serratus are the only large, structuring perennial brown macroalgae in the low salinity waters of the Swedish coast of the Baltic Proper. Since the 1970s there are reports of declining Fucus vesiculosus stands from several locations around the Baltic Proper, but also indications of recoveries e.g. LÄS MER
8. Factors structuring Fucus communities at open and complex coastlines in the Baltic Sea
Sammanfattning : This thesis deals with physical factors and biological interactions affecting the distribution of two fucoid species, Fucus vesiculosus and F. serratus, in the Baltic Sea. Studies have been carried out in two quite different environments: an archipelago, and an open rocky coast. LÄS MER
9. Stable isotope studies of contaminant and material transport in Baltic pelagic food-webs
Sammanfattning : Both carbon and nitrogen appear in nature as different stable isotopes. Many natural processes affect the relative proportions of heavy and light isotopes in predictable ways. The isotopic composition of organisms and other organic materials can therefore serve as records of the processes involved in their formation. LÄS MER
10. Trends and exposure of naturally produced brominated substances in Baltic biota - with focus on OH-PBDEs, MeO-PBDEs and PBDDs
Sammanfattning : The semi-enclosed and brackish Baltic Sea has become heavily polluted by nutrients, anthropogenic organic and inorganic chemicals via human activities. Persistent organic pollutants (POPs) have been thoroughly investigated due to their linkage to toxic effects observed in Baltic biota. There has been far less focus on semi-persistent pollutants e.
