    Abstract : 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. READ MORE

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

    Abstract : 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. READ MORE

  5. 3. Spatial Models of Gene Patterns in Plants

    Abstract : 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. READ MORE
