    Sammanfattning : A sustainable future demands a transition from oil to biomass to produce fuels, chemicals, commodities, and energy. However, to generate the predicted amount of bioenergy required by 2050, all the biomass harvested today should be utilized. One type of biomass that has received relatively little attention is seaweeds. LÄS MER

  3. 2. Seaweed Invasions and Novel Chemical Defences

    Sammanfattning : Biological invasions pose a risk to the biodiversity and the functioning of ecosystems in invaded areas. The reasons why some introduced species become dominant and widespread in their new environments is still largely an unsettled question. LÄS MER

  4. 3. Shell Age Economics : Marine Gathering in the Kingdom of Tonga, Polynesia

    Författare :Thomas Malm; Humanekologi; []

    Sammanfattning : This monograph analyses marine gathering in the Polynesian Kingdom of Tonga from ecological, social and cognitive perspectives. The overarching issues explored are (1) the significance of marine gathering in the past and present, (2) how seaweeds and marine invertebrates have been perceived, classified, named and used, (3) how they have been implicated in social relations, and (4) how the integration of the islands into the modern world system has affected the marine environment and the exploitation of its resources.
