2. 6. 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. 7. Assessment of dietary patterns and prey consumption of marine mammals: Grey seals (Halichoerus grypus) in the Baltic Sea

   Author : Karl Lundström; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; grey seal; Halichoerus grypus; Baltic Sea; diet; predation; fish; consumption; fatty acid signature analysis; bioenergetics; foraging ecology;

   Abstract : The Baltic Sea has been severely affected by pollution and resource overexploitation during the last centuries. The grey seal (Halichoerus grypus) is a good example of how a species can be affected by such changes. READ MORE

5. 8. Baltic cod predation: mechanisms, impact on prey, implications for fisheries

   Author : Nataliia Kulatska; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Trophic interactions are fundamental in the functioning of ecosystems. Predator-prey interactions between cod (Gadus morhua), herring (Clupea harengus) and sprat (Sprattus sprattus) in the Baltic Sea are typical examples of strong trophic interactions with consequences on the structure of this ecosystem.

6. 9. Exploring genetic diversity in natural and domestic populations through next generation sequencing

   Author : Nima Rafati; Leif Andersson; Carl-Johan Rubin; Alvaro Martinez Bario; Craig Primmer; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecological adaptation; seasonal reproduction; Atlantic herring; domestication; speciation; rabbit; skeletal atavism; Shetland ponies; NGS; SMRT sequencing; genome; transcriptome; assembly; structural variation; genetic diversity; HCE; TSHR; SHOX; CRLF2;

   Abstract : Studying genetic diversity in natural and domestic populations is of major importance in evolutionary biology. The recent advent of next generation sequencing (NGS) technologies has dramatically changed the scope of these studies, enabling researchers to study genetic diversity in a whole-genome context.

7. 10. QSBMR Quantitative Structure Biomagnification Relationships : Studies Regarding Persistent Environmental Pollutants in the Baltic Sea Biota

   Author : Katrin Lundstedt-Enkel; Jan Örberg; Per Larsson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Biomagnification; Multivariate modelling of environmental data; Transport of contaminants; Environmental toxicology; Biologi; Biology; Biologi;

   Abstract : I have studied persistent environmental pollutants in herring (Clupea harengus), in adult guillemot (Uria aalge) and in guillemot eggs from the Baltic Sea. The studied contaminants were organochlorines (OCs); dichlorodiphenyltrichloroethanes (DDTs), polychlorinated biphenyls (PCBs), hexachlorobenzene (HCB), hexachlorocyclohexanes (HCHs), and brominated flame retardants (BFRs); polybrominated diphenylethers (PBDEs) and hexabromocyclododecane (HBCD).
