1. Ecophysiological responses of Baltic and Atlantic Fucus vesiculosus to environmental factors
Sammanfattning : The Baltic Sea is a species-poor ecosystem where marine species coexist with freshwater species. The Baltic Sea offers low salinity, low content of inorganic carbon, long cold winters and no tides. LÄS MER
2. Conservation of landlocked Atlantic salmon in a regulated river : Behaviour of migratory spawners and juveniles
Sammanfattning : Hydropower dams represent one of the major threats to river ecosystems today. The dams block migratory routes in many rivers, which is problematic for migratory fish species. Trap-and-transport may be an alternative to fish passage solutions, as a strategy to compensate for lost river connectivity. LÄS MER
3. Out of Africa : African influences in Atlantic creoles
Sammanfattning : .... LÄS MER
4. MHC and genomic diversity in Atlantic salmon (Salmo salar L.)
Sammanfattning : In this thesis I present studies concerning genomic diversity and genetic heterogeneity as well as the evolution and maintenance of genetic variation at a specific immune defence gene in Atlantic salmon (Salmo salar, L.). LÄS MER
5. Genetic Adaptation and Speciation in Darwin’s Finches and Atlantic Herring
Sammanfattning : Natural selection acts on existing genetic variation to drive genetic adaptation of organisms to various ecological niches. Interaction between closely related populations, through processes such as competition and hybridization, may either lead to their divergence or population fusion, which has consequences for adaptation and the formation of species.
