  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

  6. 4. Reproduction and moult in pied and collared flycatchers (Ficedula hypoleuca and F. albicollis) : A life-history approach

    Author : Christer Hemborg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Breeding time; Costs of reproduction; Long-distance migrant; Moult-breeding overlap; Sexual conflict; Survival probability; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Animal Ecology; zooekologi;

    Abstract : This thesis examines the trade-offs between investments in reproduction and self-maintenance (moult) in pied and collared flycatchers (Ficedula hypoleuca and F. albicollis). These two long-distance migratory passerine bird species were studied on the breeding grounds in Fennoscandia and in England. READ MORE

  7. 5. Conservation ecology of the thick-shelled river mussel Unio crassus : The importance of parasite-host interactions

    Author : Lea Dominique Schneider; E. Martin Österling; P. Anders Nilsson; Johan Höjesjö; Caryn Vaughn; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Endangered species; freshwater mussels; host fish species; parasite-host; river; stream; Unio crassus; Unionoida; Biology; Biologi;

    Abstract : Unionoid mussels are globally threatened and their conservation requires species-specific knowledge on their ecology and parasite-host interaction. Unio crassus is one of Europe’s most threatened unionoid species and has a temporary obligate parasitic life stage (glochidia) on fish. READ MORE
