1. 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
2. Across landscapes and seascapes : The movement ecology of diving and flying guillemots and gulls during breeding
Sammanfattning : Most seabirds breed colonially, at which time they make central-place foraging trips. Parents must collect food both for themselves and for egg production/chick-rearing. LÄS MER
3. Prehistoric human impact on wild mammalian populations in Scandinavia
Sammanfattning : This thesis aims to study the interactions of pre-agricultural societies in Scandinavia with wild mammals, for example in terms of hunting and translocation. More specifically, the aim is to investigate the possibility of identifying examples of overexploitation, targeted hunting or translocation of wild mammals in prehistoric Scandinavia, and to discuss the implications this could have had for both the wild animals and the humans.

4. Determination of some polybrominated flame retardants in biota, sediment and sewage sludge
Sammanfattning : Brominated flame retardants (BFRs) are mainly used in different polymers, and can be released to the environment during industrial processes, during the entire life-time of the flame-retarded product and after disposal. The aim of the present study was to gain knowledge about occurrence and concentrations of some BFRs in the environment, to search for sources for these chemicals and to investigate changes in concentrations over time.
