  1. 6. Speciation genetics of recently diverged species

    Författare :Venkat Talla; Niclas Backström; Nicola Nadeau; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Speciation; Leptidea; Lepidoptera; chiffchaff; Cryptic species; genome-scan; Diapause; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Species differentiation can be a consequence of evolutionary forces including natural selection and random genetic drift. Patterns of genomic differentiation vary across the tree of life. This variation seems to be dependent on, for example, differences in genomic architecture and molecular mechanisms. LÄS MER

    Sammanfattning : Chlamydiae is a phylum of obligate intracellular bacteria. They have a conserved lifecycle and infect eukaryotic hosts, ranging from animals to amoeba. Chlamydiae includes pathogens, and is well-studied from a medical perspective. LÄS MER

  7. 10. Computational problems in evolution : Multiple alignment, genome rearrangements, and tree reconstruction

    Författare :Isaac Elias; Jens Lagergren; Lior Pachter; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distance Methods; Tree reconstruction; Sorting by Transpositions; multiple alignment; ancestral sequences; Computer science; Datavetenskap;

    Sammanfattning : Reconstructing the evolutionary history of a set of species is a fundamental problem in biology. This thesis concerns computational problems that arise in different settings and stages of phylogenetic tree reconstruction, but also in other contexts. LÄS MER
