  1. 11. Exploring the role of gene duplications in plant-insect interactions

    Författare :Hanna Nicole Dort; Christopher Wheat; Noah Whiteman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plant-insect interactions; comparative genomics; detoxification; transcriptomics; nitrile-specifier proteins; butterflies; populationsgenetik; Population Genetics;

    Sammanfattning : As evolutionary biologists, we are often curious about the genomic origins of our favorite adaptations. Although some innovations certainly arose de novo, many more originated through the process of whole-gene or within-gene duplication. LÄS MER

  4. 13. Mobility and emigration in butterflies

    Författare :Karin Enfjäll; Olof Leimar; Michel Baguette; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Keywords: conspecific density; dispersal; evolution; flight-behaviour; information; sexual conflict; social interactions; Ethology and behavioural ecology; Etologi och beteendeekologi; etologi; Ethology;

    Sammanfattning : Because of its implications for the survival of many species, dispersal plays a key role in conservation biology. A good knowledge about the different factors that influence dispersal decisions is crucial for the understanding of inter-population movements. LÄS MER

  5. 14. Templating and self-assembly of biomimetic materials

    Författare :Christian Mille; Lennart Bergström; Mika Linden; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biomimetic; biotemplating; self-assembly; triply periodic minimal surfaces; the gyroid; photonic crystals; band gap; structural color; chirality; butterflies; membrane proteins; lipid bilayers; sol-gel; mesostructured; polyhedral nanofoams; Materials Chemistry; materialkemi;

    Sammanfattning : This thesis focuses on the use of biomolecular assemblies for creating materials with novel properties. Several aspects of biomimetic materials have been investigated, from fundamental studies on membrane shaping molecules to the integration of biomolecules with inorganic materials. LÄS MER

  7. 15. The evolution of territoriality in butterflies

    Författare :Martin Bergman; Christer Wiklund; Ronald Rutowski; Stockholms universitet; []
    Nyckelord :territoriality; Lepidoptera; sexual selection; mating success; mate locating behaviour; resource-holding potential; motivation; courtship solicitation; NATURAL SCIENCES; NATURVETENSKAP; zoologisk ekologi; Animal Ecology;

    Sammanfattning : Competition over mating opportunities is a conspicuous characteristic of animal behaviour. In many butterfly species the males establish territories in places advantageous for encountering females. This thesis addresses questions about how territoriality has evolved and is maintained in butterflies. LÄS MER
