    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phenology; Life cycle regulation; Phenotypic plasticity; Local adaptation; Butterflies; Diapause; Pupal development; Anthocharis cardamines; Herbivore – host plant interaction; etologi; Ethology;

    Sammanfattning : Animals and plants in temperate regions must adapt their life cycle to pronounced seasonal variation. The research effort that has gone into studying these cyclical life history events, or phenological traits, has increased greatly in recent decades. LÄS MER

  4. 3. Allocation of body resources to reproduction in butterflies

    Författare :Fredrik Stjernholm; Bengt Karlsson; Christer Wiklund; Jane K. Hill; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Zoology; Ecology; Butterflies; Reproduction; Life histories; Trade-offs; Resource use; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : The life-history of an organism can be studied and understood in terms of acquisition and expenditure of resources. In butterflies, the use of resources for reproduction has been the focus of much research due to the possibility to easily quantify both the input of resources from different sources over the life-cycle as well as the partitioning of these resources to reproduction.
