  1. 1. The evolutionary history of Geum (Rosaceae, Colurieae) : a study of ancient allopolyploid speciation

    University dissertation from Stockholm : Botaniska institutionen

    Author : Jenny E. E. Smedmark; Stockholms universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geum; Rosaceae; molecular phylogeny; allopolyploidy; morphological evolution; gynoecial development; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Allopolyploid speciation plays an important role in flowering plant evolution. Its contribution to diversity has been suggested to be significant in Geum. READ MORE

  2. 2. Context dependency of plant – animal interactions

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Malin A. E. König; Stockholms universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Anthocharis cardamines; attack intensity; Cardamine pratensis; cytotype; herbivory; larval fitness; oviposition; phenology; plant-animal interactions; plant resistance; plant tolerance; polyploidy; spatial variation; trait variation; Plant Ecology; växtekologi;

    Abstract : The strength and direction of interactions between organisms vary spatially across the landscape. Traditionally, the focus has been on how trait variation affects the interactions between species. However, differences in abiotic and biotic environmental factors may also alter the distribution, phenology and behavior of the interacting species. READ MORE

  3. 3. Microstructure and Gelation Behaviour of High Methoxyl and Low Methoxyl Pectin Gels and their Mixtures

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Caroline E E Löfgren; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; rheology; kinetic behaviour; LM pectin; transmission electron microscopy; calcium; microstructure; gel formation; sucrose; HM pectin; pectin mixtures;

    Abstract : The objective of this thesis was to explore the functional behaviour of high methoxyl (HM), low methoxyl (LM) and mixed HM/LM pectin gels of different chemical characteristics with emphasis on microstructure and kinetic rheological behaviour. The rheological properties and the structure of pectin gel networks were investigated for pectins under different sucrose, calcium and pH conditions by the means of oscillatory measurements and transmission electron microscopy (TEM).

    Abstract : It is recognized in international research that the public sector has been transformed into a networked, open and more flexible, informal and interactive governance structure. This is described as a transition from "government to governance". Sweden is one of the international leaders with regards to e-government development. READ MORE
