1. 16. Making complex commons work : identifying critical social-ecological factors and mechanisms for sustainable ecosystem management

   Författare :Caroline Schill; Therese Lindahl; Björn Vollan; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Agent-based modelling; Behavioural experiments; Collective action; Common-pool resources; Cooperation; Ecological complexity; Knowledge sharing; Regime shifts; Social-ecological systems; Sustainable management; Thresholds; Uncertainty; Sustainability Science; vetenskap om hållbar utveckling;

   Sammanfattning : Collective action holds the key to many sustainability challenges, from local to global scales. Whether it is to manage community-based fisheries or take action against climate change or biodiversity loss – the question on how to overcome the conflict between individual and collective interests (i.e. LÄS MER

3. 17. Off the grid

   Författare :Mike Bode; Staffan Schmidt; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; artistic research; visual concepts; situated image; dialogue; ecological and political engagement; off grid living; housing estate suburbia; travel; self-definition; community; institution; isomorphic; lived third space;

   Sammanfattning : Off the grid is an artistic research thesis which puts a Swedish housing estate in a video interview dialogue with homeowners in the Northeastern US through focusing on three topics: travel, self-definition, and community. Based on the situated, visual and conceptual image the project merges seemingly incompatible experiences: eight residents in Husby, an immigrant community outside Stockholm, and eight households not connected to the utility grid, in upstate areas of New England and New York State – and two artistic researchers at University of Gothenburg.

4. 18. Extinctions in Ecological Communities : direct and indirect effects of perturbation on biodiversity

   Författare :Alva Curtsdotter; Bo Ebenman; Peter Münger; Elisa Thébault; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In the dawning of what may become Earth’s 6th mass extinction the topic of this thesis, understanding extinction processes and what determines the magnitude of species loss, has become only too relevant. The number of known extinctions (~850) during the last centuries translates to extinction rates elevated above the background rate, matching those of previous mass extinction events. LÄS MER

5. 19. In situ remediation of contaminated sediments using thin-layer capping : effectiveness in contaminant retention and ecological implications

   Författare :Göran Samuelsson; Jonas Gunnarsson; Maria Granberg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thin layer capping; sediment remediation; activated carbon; contaminated sediment; benthic community; Systems Ecology; systemekologi;

   Sammanfattning : Hydrophobic organic contaminants (HOCs) often reside in sediment sorbed to particles, most tightly to particles with high content of organic carbon. If persistent, such pollutants can accumulate in the sediment for many years and constitute a contamination risk for sediment-living organisms and organisms at higher trophic levels, including humans.

7. 20. Microbial Community Assembly during Aerobic Granulation

   Författare :Raquel Liebana; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aerobic granular sludge; granulation; washout dynamics; membrane bioreactors; sequencing batch reactors; fluorescence in-situ hybridization; microbial community dynamics; reproducibility;

   Sammanfattning : Environmental deterioration together with the increasingly restrictive legislation of water quality standards have led to a demand for compact, efficient and less energy consuming technologies for wastewater treatment. Aerobic granular membrane bioreactors (AGMBRs) combine the advantages of aerobic granular sludge and membrane filtration. LÄS MER
