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. Heathlands – A Lost World?

   Author : Mattias Lindholm; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heathland; Calluna vulgaris; Conservation biology; Management; Coleoptera; Carabidae; Lycosidae; Conservation strategy;

   Abstract : Heathland is a familiar landscape type in southwest Sweden. It is open with few trees, and the vegetation is dominated by dwarf-shrubs growing on nutrient-poor soils. Dry heaths with Heather Calluna vulgaris and wet heaths with Bell Heather Erica tetralix are common vegetation communities in the heathland, and they often form mosaics. READ MORE

7. 5. To survive and reproduce in a cyclic environment – demography and conservation of the Arctic fox in Scandinavia
