1. Ecological aspects of the breeding biology of the Guillemot Uria aalge in the Baltic Sea
Sammanfattning : .... LÄS MER
2. Seabirds as food for thought : An integrative study on seabird ecology and ecosystem services in changing marine systems
Sammanfattning : The importance of the benefits that humans obtain from the oceans is increasingly recognized, along with the rapid decline in marine resources that threatens these benefits. Studying seabirds – top predators in marine ecosystems, can provide insights about multiple pressures and the state of the oceans. LÄS MER
3. Man, murres and modern fisheries : A case study in the Baltic Sea
Sammanfattning : Overfishing and climate change put increasing pressure on marine systems, with effects on commercially targeted fish and top predators dependent on these resources. To achieve sustainable resource use, governance mechanisms need to incorporate knowledge about ecosystem dynamics. LÄS MER
4. Temporal and spatial trends of organohalogens in guillemot (Uria aalge) from North Western Europe
Sammanfattning : The Arctic and sub-Arctic region of the North Atlantic is a remote area, also in relations to environmental contaminants, such as POPs, BFRs and last but not least, PFCs. Both the BFRs and PFCs are considered emerging pollutants of significant environmental concern. LÄS MER
5. Complexity and Change in a Simple Food Web : Studies in the Baltic Sea (FAO Area 27.IIId)
Sammanfattning : An influence at one trophic level can result in dynamic impacts also on other components of a food web. These dynamics are known as trophic cascades, and can be both top-down and bottom-up. After a near-collapse of the Baltic cod Gadus morhua stock in the 1980s, its main prey sprat Sprattus sprattus increased dramatically. LÄS MER
