  1. 1. Man, murres and modern fisheries : A case study in the Baltic Sea

    Detta är en avhandling från Stockholm : Department of Systems Ecology, Stockholm University

    Författare :Martina Kadin; Henrik Österblom; Olof Olsson; Carl Folke; Morten Frederiksen; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seabirds; ecosystem dynamics; fisheries; indicators; ecosystem services; Baltic Sea; common murre; common guillemot; Uria aalge; Natural Resources Management; naturresurshushållning;

    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

  2. 2. Bis(4-chlorophenyl) sulfone and PCB methyl sulfone metabolites Trends and chirality in the Baltic Sea environment

    Detta är en avhandling från Stockholm : Institutionen för miljökemi

    Författare :Karin Norström; Åke Bergman; Mats Olsson; Roland Kallenborn; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bis 4-chlorophenyl sulfone; PCB methyl sulfone; Baltic Sea; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi;

    Sammanfattning : The Baltic Sea was earlier identified as a highly polluted brackish water body and still is. The high concentrations of polychlorinated biphenyls (PCBs), p,p’-DDT and related compounds led to severe effects on several species in the Baltic region. LÄS MER

  3. 3. Analysis of Perfluoroalkyl Acids in Swedish Biota  : Temporal trends, tissue distribution and toxicity

    Detta är en avhandling från Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Sammanfattning : Perfluorinated alkyl acids (PFAS) are ubiquitous environmental contaminants. They are found in high concentrations in top predators worldwide, with perfluorooctane sulfonate (PFOS) as the predominant compound. LÄS MER

  4. 4. Seabirds as food for thought : An integrative study on seabird ecology and ecosystem services in changing marine systems

    Detta är en avhandling från Stockholm : Stockholm Resilience Centre, Stockholm University

    Författare :Martina Kadin; Thorsten Blenckner; Morten Frederiksen; Olof Olsson; Johan Elmberg; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; seabirds; ecosystem services; social-ecological systems; marine systems; fisheries; foraging ecology; provisioning behaviour; common murre; common guillemot; Uria aalge; Stora Karlsö; Baltic Sea; Natural Resources Management; naturresurshushållning;

    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
