  2. 1. Population Genetic Structure of Black Grouse (Tetrao tetrix) : From a Large to a Fine Scale Perspective

    Author : Carolina Corrales Duque; Jacob Höglund; Staffan Bensch; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; black grouse; control region; demographic expansion; kin selection; lek; microsatellites; non-invasive sampling; postglacial colonisation; philopatry; phylogeography; sex-biased dispersal; spatial genetics; subspecies; suture zone; refugia; Biology; Biologi; Systematics and phylogenetics; Systematik och fylogeni; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Abstract : Black grouse (Tetrao tetrix) is a bird species with a lek mating system found in the Palearctic boreal taiga. It is assumed that it has a continuous distribution along Scandinavia and Siberia, whereas in Central Europe it has declined during the last decades. READ MORE

  4. 2. Systematics of polyploid Dactylorhiza (Orchidaceae) - genetic diversity, phylogeography and evolution

    Author : Sofie Olofsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microsatellites; allozymes; ITS; plastid DNA; Dactylorhiza majalis ssp. traunsteineri; allopolyploidy; AFLPs; immigration history; diploidization; hybridization;

    Abstract : This thesis examines genetic variation in allotetraploids of the Dactylorhiza incarnata/maculata polyploid complex in different parts of Europe. The molecular markers used were AFLPs, allozymes, ITS, nuclear microsatellites and plastid DNA markers. READ MORE

  5. 3. Population Fragmentation and Genetic Variation in Grouse

    Author : Jobs Karl Larsson; Jacob Höglund; Stuart B. Piertney; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Bonasa sewerzowi; bottleneck; genetic drift; genetic variation; inbreeding; isolation; microsatellites; population structure; Tetrao tetrix; Biologi; Biology; Biologi;

    Abstract : In this thesis the genetic variation of two grouse species, the Chinese grouse (Bonasa sewersowi) and the Black grouse (Tetrao tetrix) was examined with neutral genetic markers: microsatellites. Habitat fragmentation and isolation leads to structuring among and loss of genetic variation within populations. READ MORE

  6. 4. Studies of declining populations - temporal genetic analyses of two arctic mammals

    Author : Veronica Nyström; Anders Angerbjörn; Lisette Waits; Stockholms universitet; []
    Keywords : Vulpes lagopus; Mammuthus primigenius; population reduction; extinction; ancient DNA; mitochondrial DNA; microsatellites; genetic variation; NATURAL SCIENCES; NATURVETENSKAP; zoologisk ekologi; Animal Ecology;

    Abstract : Many populations and species are threatened with extinction today. Understanding the extinction process and the factors behind population decline is therefore important. READ MORE

  7. 5. Genome Divergence in Progress - a population genetic analysis of the allopolyploid Arabidopsis suecica and its maternal parent A. thaliana

    Author : Mattias Jakobsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytogenetik; Genetik; cytogenetics; Genetics; sequence polymorphism; microsatellites; population structure; polyploidy; single origin; Arabidopsis thaliana; Arabidopsis suecica; genome evolution; evolutionary history; Plant genetics; Växtgenetik;

    Abstract : The evolutionary history of the allotetraploid Arabidopsis suecica and its maternal parent Arabidopsis thaliana is analyzed in the thesis in terms of genetic variation in the natural populations of the two species. The earliest phase of the speciation event in which the genomes of A. thaliana and A. READ MORE
