  3. 2. Population Genetic Analyses of Natal Dispersal and Substructure in Three Bird Species

    Författare :Tobias Sahlman; Jan Ekman; Jacob Höglund; Ben J. Hatchwell; Uppsala universitet; []
    Nyckelord :Ecology; Perisoreus infaustus; Gallinago media; Lagopus muta; relatedness; philopatry; biased dispersal; phylogeography; microsatellite; mitochondrial DNA; Ekologi;

    Sammanfattning : Genetic variation within and among populations is a result of past and ongoing processes. Among the most important of such processes are dispersal, habitat fragmentation and selection. This thesis use neutral genetic variation as a tool to investigate these processes in three bird species. LÄS MER

  4. 3. The evolution of flat periwinkles Littorina fabalis and L. obtusata emhasizing mitochondrial introgression and restricted recombination

    Författare :Petri Kemppainen; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Speciation; Local adaptations; Ecotypes; Mitochondrial DNA; Introgression; Restricted recombination; Positive selection; Inversions; Chromosomal rearrangements;

    Sammanfattning : The evolution of species takes in general very long time and different mechanisms are likely to operate during the various stages of this process. Accordingly speciation should be studied at different levels of species divergence. LÄS MER

  5. 4. Mitochondria and Human Evolution

    Författare :Max Ingman; Ulf Gyllensten; Peter Underhill; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; mitochondria; hominidae; human evolution; population genetics; Genetik; Clinical genetics; Klinisk genetik; Genetics; genetik;

    Sammanfattning : Mitochondrial DNA (mtDNA) has been a potent tool in studies of the evolution of modern humans, human migrations and the dynamics of human populations over time. The popularity of this cytoplasmic genome has largely been due to its clonal inheritance (in Man) allowing the tracing of a direct genetic line. LÄS MER

  7. 5. Evolutionary History of the Root Vole (Microtus oeconomus) as Revealed by Y Chromosome and Mitochondrial DNA sequences

    Författare :Cecilia Brunhoff; Malmö Patologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetics; colonization history; phylogeography; root vole; cytogenetics; Genetik; cytogenetik;

    Sammanfattning : The root vole (Microtus oeconomus) is a rodent with Holarctic distribution. In fact, it is the only Microtus vole found in both Eurasia and North America. Phylogeographic analyses of the root vole from across its distribution range were performed using mitochondrial and Y chromosome DNA sequences. LÄS MER
