  4. 2. Marine Seaweed Invasions : the Ecology of Introduced Fucus evanescens

    Author : Sofia A. Wikström; Lena Kautsky; Ove Eriksson; Paul Lavery; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biological invasions; marine; seaweed; algae; herbivory; enemy release hypothesis; phlorotannins; anti-fouling; Fucus evanescens; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : Biological invasions are an important issue of global change and an increased understanding of invasion processes is of crucial importance for both conservation managers and international trade. In this thesis, I have studied the invasion of the brown seaweed Fucus evanescens, to investigate the fate and effect of a perennial, habitat-forming seaweed introduced to a coastal ecosystem.

  5. 3. Searching for sustainable aquaculture governance : A focus on ambitions and experience

    Author : Ola Luthman; Rickard Lalander; Fred Saunders; Max Troell; Megan Bailey; Södertörns högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aquaculture; policy; environmental governance; Social-Ecological Systems; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Abstract : Aquaculture is one of the most diverse food-producing industries and is suggested as a key solution to a growing global food demand. It has been argued that aquaculture has the potential to expand sustainably in most parts of the world, especially in the EU where consumption far out weighs production. READ MORE

  6. 4. On the processing and properties of cellulose-containing polymeric materials

    Author : Ruth Arino Marine; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dispersion; extrusion; injection moulding; ionic liquids; compounding; ethylene-acrylic acid copolymer; gels; cellulose fibres; rheological properties;

    Abstract : Cellulose fibres have properties such as renewability, biodegradability, very good availability and low cost that make them very attractive as a reinforcement for thermoplastic polymers. Other more specific favourable properties are low density, high specific stiffness, low abrasive nature and their potential for modification. READ MORE
