  4. 12. Mobility and emigration in butterflies

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

    Abstract : 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. READ MORE

  5. 13. On the origin of polymorphism - consequences of competition and predation in heterogeneous environments

    Author : Jennie Holmér; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; source-sink dynamics; predation; competition; dispersal; polymorphism; evolution; crypsis; adaptive dynamics;

    Abstract : In this thesis, I have studied when an initially monomorphic population can diverge into two morphs in a heterogeneous environment. Evolution is driven by competition for resources or predation. In Paper I, we studied source-sink dynamics during evolution in an environment with two types of resource of different abundance in two habitats. READ MORE

  6. 14. Community and food web assembly on virgin habitat islands - The nunatak saga

    Author : Maria Ingimarsdottir; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; allochthonous material; arthropods; community assembly; corridor; dispersal; Iceland; metacommunity; nunataks; primary succession; stable isotopes.;

    Abstract : The classical view of primary community assembly is that colonisation by plants is essential before invertebrates can establish. It has been recognised, however, that invertebrates can establish before plants, and that they may be important in the first steps of community assembly. READ MORE

  7. 15. The dispersal–vicariance pendulum and butterfly biogeography

    Author : Ullasa Kodandaramaiah; Niklas Wahlberg; Brett Riddle; Stockholms universitet; []
    Keywords : Junonia; Coenonympha; Coenonymphina; Mycalesina; historical biogeography; vicariance; dispersal; DIVA; NATURAL SCIENCES; NATURVETENSKAP; zoologisk ekologi; Animal Ecology;

    Abstract : The relative importance of dispersal and vicariance in speciation is a subject of long standing debate. The earliest historical biogeographers invoked dispersal to explain disjunct distributions. READ MORE
