    Sammanfattning : Beachcast or beach wrack, washed-up algae and seaweed, used to be a highly sought-after agricultural resource (fertiliser and soil conditioner) in coastal communities around the world before being replaced by chemical fertilisers, but considering the talks of a circular bio-economy – can we reintroduce it? Since the abandonment of beachcast in agriculture, the amount of beachcast has significantly increased as an effect of eutrophication caused by the use of chemical fertiliser, and the material is commonly considered waste. Meanwhile, soils have degraded and need the multiple positive effects on agroecosystems that beachcast could provide. LÄS MER

  3. 2. Structural changes in marine ecosystems – the application of novel network approaches to understand marine regime shift

    Författare :Johanna Yletyinen; Thorsten Blenckner; Örjan Bodin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Anthropogenic drivers, such as climate change and fishing, have severe, often unexpected impacts on marine ecosystems. Species responses to drivers may have cascading effects through ecological communities, potentially changing the structure and functioning of the food web. LÄS MER
