    Abstract : The Understen-Märket trench is located in the Southern Quark and is the only deep-water connection between the Baltic Propper and the Gulf of Bothnia. Bathymetric mapping reveals a number of eroded channels and drift deposits exists on the seafloor, indicating that the area is heavily affected by current activity. READ MORE

  3. 2. Experimental Spironucleus infections in Atlantic salmon (Salmo salar) : Hidden secrets of the life cycle of Spironucleus salmonicida revealed

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Anders Alfjorden; [2018]
    Keywords : Parasite; Salmon; Infection; Diplomonada; Spironucleus;

    Abstract : We have performed experimental infections of Atlantic salmon (Salmo salar) from the Baltic Sea region with the protozoan parasite Spironucleus salmonicida. By this infection trial we have been able to show that the life cycle may use an alternative route of transmission. READ MORE

  4. 3. Seasonal changes in clupeids maturation constrains the food quality of chicks of the common guillemot (Uria aalge) : A case study of a potential mismatch, from the perspective of the common guillemot chicks on Stora Karlsö, the Baltic Sea

    Author : Amelie Nordström; [2016]
    Keywords : Ringed seal; Baltic Sea; Persistent Organic Pollutants; Sample pre-treatment;

    Abstract : Persistent organic pollutants such as polychlorinated biphenyls (PCBs), DDT and polybrominated diphenyl ethers (PBDEs) tend to accumulate in biota and are transferred through the aquatic food web, which result in a high accumulation in marine mammals. In recent years various novel flame retardants (nBFRs), which have replaced the banned PBDEs, have also started to occur in the environment. READ MORE
