2. 1. SEA CHANGE : Social-ecological co-evolution in Baltic Sea fisheries

   Author : Jonas Hentati-Sundberg; Henrik Österblom; Joakim Hjelm; Trevor Branch; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; resilience; social-ecological systems; complex adaptive systems; fisheries; Baltic Sea; Sustainability Science; vetenskap om hållbar utveckling;

   Abstract : Sustainable management of natural resources requires an in-depth understanding of the interplay between social and ecological change. Linked social-ecological systems (SES) have been described as complex adaptive systems (CAS), which mean that they are irreducible, exhibit nonlinear dynamics, have interactions across scales and are uncertain and unpredictable.

4. 2. The neurotoxin β-N-methylamino-L-alanine (BMAA) and 2,4-diaminobutyric acid (DAB) : possible risk of human exposure, and the effect and function in diatoms

   Author : Sea-Yong Kim; Sara Rydberg; Sandra Banack; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; växtfysiologi; Plant Physiology;

   Abstract : The toxic secondary metabolites β-N-methylamino-L-alanine (BMAA) and 2,4-diaminobutyric acid (DAB) produced by phytoplankton groups such as cyanobacteria, diatoms and dinoflagellates are known to cause neurotoxicity in vertebrates. BMAA has been linked to development of the neurodegenerative diseases amyotrophic lateral sclerosis/Parkinsonism dementia complex (ALS/PDC) and Alzheimer's disease. READ MORE

5. 3. Radionuclides in the Baltic Sea : Ecosystem models and experiments on transport and fate

   Author : Linda Kumblad; Nils Kautsky; Ulrik Kautsky; Michael Gilek; Michael Thorne; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; radionuclide; baltic sea; ecosystem model; ecosystem dynamics; risk assessment; safety assessment; benthic invertebrates; bioturbation; bioaccumulation; remobilisation; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

   Abstract : Manmade radionuclides have been introduced to the environment for almost a century. The main source has been the nuclear weapons testing programmes, but accidental releases from the nuclear power production industries have also contributed. The risk to humans from potential releases from nuclear facilities is evaluated in safety assessments. READ MORE

6. 4. Science-policy interaction in the governance of complex socio-ecological risks : The case of chemicals management in the Baltic Sea

   Author : Oksana Udovyk; Michael Gilek; Johan Hedrén; Sivlio Funtowicz; Södertörns högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Risk; Uncertainty; MSFD; HELCOM; REACH; post-normal science; precautionary; participation; Östersjö- och Östeuropaforskning; Baltic and East European studies;

   Abstract : In this thesis, I examine knowledge production and science-policy interaction associated with the management of chemical substances in the Baltic Sea under conditions of uncertainty and complexity. The thesis is primarily based on a qualitative analysis of policy documents and reports produced by the European Union (EU), the Helsinki Commission, the Swedish Chemicals Agency, and Gothenburg municipality, as well as 30 semi-structured interviews with scientific experts, policy makers, and government officials with knowledge and working experience in the relevant policy arenas.

7. 5. A Deep Dive into Sediments : Exploring approaches to assess environmental risks and achieving environmental goals in management of contaminated sediments in Sweden

   Author : Peter Bruce; Clare Bradshaw; Yvonne Ohlsson; Anna Sobek; Sabine Apitz; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sediment; risk assessment; risk evaluation; risk management; contaminants; regulations; weight of evidence; line of evidence; environmental goals; environmental management; guidelines; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : Contaminated sediments are common, especially near urban and industrialized areas, and they can have negative ecological effects. In three studies, I explore the challenges for environmental management of contaminated sediments, focusing on environmental risk assessment (ERA) in Sweden. READ MORE
