  1. 1. Evolution of Plants : a mathematical perspective

    Författare :Magnus Lindh; Åke Brännström; Jacob Johansson; Mats G Larson; Lennart Persson; Claus Rüffler; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Evolution; plants; mathematics; optimization; optimal control; adaptive dynamics; flowering; seasons; tree crown; drought; taproot; trade-off; strategy; trait; ESS; NPP; LAI; Red Queen; Mathematics; matematik;

    Sammanfattning : The Earth harbors around 300 000 plant species. The rich and complex environment provided by plants is considered a key factor for the extraordinary diversity of the terrestrial fauna by, for example, providing food and shelter. LÄS MER

  2. 2. 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 :NATURAL SCIENCES; NATURVETENSKAP; 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. 3. Spatial Models of Gene Patterns in Plants

    Författare :André Larsson; Institutionen för astronomi och teoretisk fysik; []
    Nyckelord :computational morphodynamics; gene regulation; spatial models; plants; development; auxin; meristem; Fysicumarkivet A:2017:Larsson;

    Sammanfattning : The growth and development of plants exhibits a striking symmetry, visible in the regular arrangement of leaves and flowers. Plant development is carefully controlled at the molecular level by gene regulatory networks, and the symmetry of plants can be observed also in the molecular patterns of gene expression. LÄS MER
