  2. 1. Ecophysiological responses of Baltic and Atlantic Fucus vesiculosus to environmental factors

    Author : Charlotta A Nygård; Nils Ekelund; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; acclimation; Atlantic; Baltic Sea; Bothnian Sea; Cd; Fucus vesiculosus; growth; high PAR; Pb; photosynthesis; salinity; stress; UV-B; Biology; Biologi;

    Abstract : 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. READ MORE

  4. 2. Conservation of landlocked Atlantic salmon in a regulated river : Behaviour of migratory spawners and juveniles

    Author : Anna Hagelin; Eva Bergman; Fleming Ian; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atlantic salmon; conservation; migration; spawning; hydropower; competition; juveniles; brown trout; hatchery reared; fallback; delay; Biology; Biologi;

    Abstract : 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. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; cytogenetik; Genetik; cytogenetics; Genetics; nucleotide diversity; isolation-by-distance; DGGE; AFLP; furunculosis; disease resistance; Arctic charr; brown trout; Atlantic salmon; population genetics; genetic variation; Mhc class IIB; Animal ecology;

    Abstract : 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.). READ MORE

  7. 5. Genetic Adaptation and Speciation in Darwin’s Finches and Atlantic Herring

    Author : Fan Han; Leif Andersson; Kjetill Sigurd Jakobsen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Darwin s finches; Atlantic herring; Population genetics; Evolution; Ecological adaptation; Speciation; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology; Bioinformatics; Bioinformatik;

    Abstract : 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.
