  6. 4. Fish in the coastal seascape : exploring ecological processes and connectivity for conservation of temperate fish communities

    Author : Thomas Staveley; Martin Gullström; Mats Björk; Regina Lindborg; Emma Jackson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; seascape ecology; landscape ecology; seagrass; marine habitats; fish; spatial analysis; connectivity; conservation; Sweden; temperate; Marine Ecology; marin ekologi;

    Abstract : The need to understand patterns and processes in the marine environment has never been so profound as today, particularly as anthropogenic pressures upon coastal regions are drastically affecting habitats and species across a vast range. One approach to further understand these patterns and processes is through the use of seascape ecology methods. READ MORE

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