    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Approximate Bayesian Computation; Mating system; Brassicaceae; flowering time; genetic diversity; Evolution; Biology; Biologi;

    Sammanfattning : Studies of demography and population structure give insight into important evolutionary processes such as speciation and diversification. In the present work I perform such studies in the genus Capsella, which has three species: C. grandiflora, an outcrossing diploid, C. rubella a selfing diploid, and C. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mating system evolution; cross- and self-fertilization; distyly; supergenes; complex phenotypic polymorphism; convergent evolution; homostyly; loss-of-function mutation; intrasexual competition; pollen; purifying selection; Linum; Arabis alpina; Ecology and Evolution; ekologi och evolution;

    Sammanfattning : The striking diversity of reproductive strategies that flowering plants exhibit remains one of the most intriguing conundrums in evolutionary biology. Pollination-related traits and mating system strategies have a major impact on the processes shaping plant evolution through their effects on genetic diversity and selection. LÄS MER
