    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Speciation; Sexual signals; Hybridization; Reinforcement; Song; Female preference; Sex-linkage; Biologi; Biology; Biologi;

    Abstract : Speciation is the process in which reproductive barriers evolve between populations. In this thesis I examine how sexual signals contribute to the maintenance, reinforcement or breakdown of reproductive barriers.Male pied flycatchers (Ficedula hypoleuca) and collared flycatchers (F. albicollis) differ in song and plumage traits.

    Abstract : Do people’s attitudes towards female genital cutting (FGC) change after they migrate from a country where the practice is common, to one where it is not? Alongside increased levels of migration, this question is increasingly being raised. This thesis aimed to expand the understanding about attitudes towards FGC held by Somali men and women in Sweden, and thereby to identify potential factors that impede or facilitate the cessation of FGC.

    Abstract : Traditionally, females have been considered to be strictly monogamous. Today, we know that females in the majority of species actively seek out and mate with several males. Trying to understand female preferences, including what benefits mate choice entails, has been the focus of intense research during the last decades. READ MORE

  7. 5. Evolutionary and mechanistic aspects of insect host plant preference

    Abstract : Plant feeding insects comprise about 25% of all animal species on earth and play an important role in all ecosystems. Although we understand that their association with plants is a key-factor driving the diversification in this group, we still have large gaps in our knowledge of the underlying processes of this relationship.
