    Abstract : Biological invasion has become a major threat to economy, ecology, global biodiversity and ecosystem function of aquatic ecosystems. The main aim of the thesis was to study the effects of the zebra mussel (Dreissena polymorpha), a versatile invasive species, on phytoplankton dynamics and ecosystem function of lakes. READ MORE

  5. 3. Anxious Leviathan : the powerful vulnerability of strong states

    Author : Tadek Markiewicz; Philip Cunliffe; Ingvild Bode; University of Kent; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Why do strong countries implement narratives of vulnerability in their wartime public communication? This dissertation solves the puzzling practice of powerful actors pursuing identifications we commonly associate with weakness and political failure. It is the first systematic study analyzing vulnerability narratives as a practice of statecraft and warcraft. READ MORE
