  1. 1. Metal accumulation by plants : evaluation of the use of plants in stormwater treatment

    Författare :Åsa Fritioff; Maria Greger; Lena Kautsky; Bert Wolterbeek; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elodea canadensis; Potamogeton natans; uptake; translocation; distribution; toxicity; salinity; temperature; and leakage; Plant physiology; Växtfysiologi;

    Sammanfattning : Metal contaminated stormwater, i.e. surface runoff in urban areas, can be treated in percolation systems, ponds, or wetlands to prevent the release of metals into receiving waters. Plants in such systems can, for example, attenuate water flow, bind sediment, and directly accumulate metals. LÄS MER

  3. 2. On the complexity of dealing with introduced plants as cultural heritage : a historical multidisciplinary study of plants introduced to Norway from 1750 to 1900, exemplified with Abies alba Mill. (European silver fir) as a case species

  4. 3. Methods for measurements of chlorophyll fluorescence, luminescence and photosynthesis in intact plants

    Författare :Erik Sundbom; Thor Bernt Trondheim Melö; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Luminiscence; delayed light emission; phytoluminography; fluorescence; in vivo chlorophyll a^ fluorescence; photosynthesis; electron transport; frost tolerance; intact plants; Physiological Botany; fysiologisk botanik;

    Sammanfattning : Methods were developed to study delayed light emission (luminiscence) and fluorescence changes in intact leaves of plants. Delayed light emission, detected from plants in darkness, was used to produce images of the plant leaves. The procedure was termed "phytoluminography". LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. Phytostabilisation : use of wetland plants to treat mine tailings

    Författare :Eva Stoltz; Maria Greger; Lena Kautsky; Marinus Otte; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phytostabilisation; wetland plants; mine tailings; Plant physiology; Växtfysiologi;

    Sammanfattning : Mine tailings can be rich in sulphide minerals and may form acid mine drainage (AMD) through reaction with atmospheric oxygen and water. AMD contains elevated levels of metals and arsenic (As) that could be harmful to animals and plants. LÄS MER
