2. Salmonid behaviour under winter conditions
Abstract : Winter conditions are believed to play an important role in the population dynamics of northern temperate stream fish, challenging the ability of fish to physiologically and behaviourally adapt. Climate change is predicted to increase both mean temperature and temperature fluctuations, especially during winter, leading to dynamic environmental conditions in terms of river ice production and flow.

3. The estrogen receptor in fish and effects of synthetic estrogens in the environment - Ecological and evolutionary perspectives and societal awareness
Abstract : Synthetic hormones are a group of pharmaceuticals used for various human and animal treatments. However, consumption and disposal of these substances have also given rise to negative effects and environmental problems for organisms in the wild which is why these substances have been classified as estrogenic endocrine-disrupting chemicals (EDCs).

4. Evolution and Ecology of AhR genes in Atlantic salmon (Salmo salar L.)
Abstract : In vertebrates, studies of the aryl hydrocarbon receptor (AhR) have been of particular interest due to its direct involvement in the toxic effects exerted by several environmental pollutants, such as PCB and dioxin. After binding to the toxic molecule, this receptor initiates transcription of several genes that are part of the biotransformation battery but most notably the cytochrome P450 (CYP) genes, which results in an excessive release of oxidative enzymes and free radicals.

5. Infectious Pancreatic Necrosis Virus (IPNV) - Structural Studies and Methodology
Abstract : Infectious pancreatic necrosis virus (IPNV) is a Birnavirus that infects salmonid fish. The infection is usually mortal for fish under six months of age, while older fish become carriers, usually without any signs of infection, and will spread the virus to other susceptible fish and to their offspring.
