  5. 3. The impact of cormorant nesting colonies on plants and arthropods

    Author : Gundula S. Kolb; Peter Hambäck; Lenn Jerling; Post David; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; seabirds; cormorants; islands; nitrogen; phosphorus; plants; arthropods; δ15N; Baltic Sea; ecological stoichiometry; species richness; species composition; numeric response; Biology; Biologi; Plant Ecology; växtekologi;

    Abstract : Seabirds concentrate large amounts of marine nutrients on their nesting islands. This nutrient input can have large consequences for island food webs and community structure. The high nutrient load may also cause runoff into surrounding waters and affect marine communities. READ MORE

  6. 4. Colonisation and extinction of vascular plants on islands off the Swedish east coast

    Author : Anders Löfgren; Lars Ericson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; plants; ecological succession; colonizing ability; population dynamics; grasslands; islands; Sweden; plant ecology; Plant Ecology; växtekologi;

    Abstract : Persistence of species is a function of colonisation and extinction among patches at a regional scale. A decrease in area and an increased isolation of suitable patches may result in a decreased colonisation rate and an increased extinction rate among species. READ MORE

  7. 5. On Textile Farming : Living Indoors

    Author : Svenja Keune; Chiara Colombi; Högskolan i Borås; []
    Keywords : Textil och mode generell ; Textiles and Fashion General ;

    Abstract : Horticultural practices are increasingly entering the private realm due to the popularity of urban gardening, indoor gardening systems, and architectural propositions to join living spaces for people and vegetable cultivation in order to promote more resilient and sustainable ways of living. While new research into symbiotic processes between living organisms and their ability to sense and reason triggers new works of art, culture, design, and architecture, the organisation of indoor plants remains mainly unaffected.
