   Abstract : This dissertation researches how perspectives in western industrial societies communicate about and give meaning to environmental degradation through case studies on the causes and effects of cultural eutrophication—namely nutrient pollution, algal blooms, and dead zones—in the Baltic Sea. Utilizing this approach, this dissertation addresses the ecological problems of cultural eutrophication in marine ecosystems by exposing normative claims humans make about the Baltic Sea and its contents as well as detailing how seas that exceed human expectations may offer insights into negotiating differing perspectives, discrepancies in power, and ways of being among humans and non-humans in marine environments.

4. 2. Control factors of the marine nitrogen cycle : The role of meiofauna, macrofauna, oxygen and aggregates

   Author : Stefano Bonaglia; Patrick Crill; Volker Brüchert; Per Hall; Chritoph Humborg; Risgaard-Petersen Nils; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nitrogen cycle; denitrification; DNRA; anammox; anoxia; hypoxia; eutrophication; meiofauna; macrofauna; aggregates; cyanobacteria; Baltic Sea; geokemi; Geochemistry;

   Abstract : The ocean is the most extended biome present on our planet. Recent decades have seen a dramatic increase in the number and gravity of threats impacting the ocean, including discharge of pollutants, cultural eutrophication and spread of alien species. READ MORE

5. 3. Environmental Systems Analysis of Wastewater Management

   Author : Erik Kärrman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The history of wastewater management tells us that efforts have been made at solving only one problem at the time; sanitation during the first half of the 20th Century followed by eutrophication of lakes and sea and, for the past ten years, recycling of nutrients. After the "Brundtland Report", 1987, a reversal of the debate occurred where water management was discussed in a more holistic manner than before. READ MORE

6. 4. Sustainable Kelp Aquaculture in Sweden

   Author : Wouter Visch; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biofouling; cryopreservation; ecosystem services; environmental impact; extractive aquaculture; gametophytes; kelp; population diversity; Saccharina latissima; seaweed cultivation; selective breeding; site selection;

   Abstract : Seaweed aquaculture is gaining more interest worldwide, including Europe. However, despite its long coast seaweed farming is still very minor in Sweden. READ MORE

7. 5. Small biotopes in agricultural landscapes: importance for vascular plants and effects of management

   Author : Therese Irminger Street; Biodiversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Small biotopes; incidental habitat; vascular plants; woody vegetation; grassland species; resource provisioning; species richness; habitat specificity; non-crop habitat; landscape complexity; heterogeneity; local management; agri-environment scheme;

   Abstract : As a consequence of agricultural intensification, large areas of non-crop habitat have been lost and farmland biodiversity has declined. Previous studies have shown that the extent of non-crop habitat influences farmland biodiversity, but the relative importance of different habitat types is less well known and the contribution of small incidental habitats to landscape-scale species richness is not fully understood.
