  1. 1. Where our feet have taken us : Examples of human contact, migration, and adaptation as revealed by ancient DNA

    Författare :Alexandra Coutinho; Mattias Jakobsson; Helena Malmström; Carina Schlebusch; Tom Gilbert; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human demography; migration; adaptation; human contact; ancient DNA; human evolution; African prehistory; Scandinavian prehistory; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Sammanfattning : In spite of our extensive knowledge of the human past, certain key questions remain to be answered about human prehistory. One involves the nature of cultural change in material culture through time from the perspective of how different ancient human groups interacted with one another. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Prehistoric human impact on wild mammalian populations in Scandinavia

    Författare :Hans Ahlgren; Kerstin Lidén; Anders Angerbjörn; Anders Götherström; Gørill Nilsen; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; hunter-gatherers; Baltic Sea; Mesolithic period; grey seal; harp seal; mountain hare; moose; ancient DNA; hunting; translocation; arkeologi med inriktning mot laborativ arkeologi; Scientific Archaeology;

    Sammanfattning : This thesis aims to study the interactions of pre-agricultural societies in Scandinavia with wild mammals, for example in terms of hunting and translocation. More specifically, the aim is to investigate the possibility of identifying examples of overexploitation, targeted hunting or translocation of wild mammals in prehistoric Scandinavia, and to discuss the implications this could have had for both the wild animals and the humans.

  5. 4. Acquired or inherited prestige? : molecular studies of family structures and local horses in Central Svealand during the Early Medieval period

    Författare :Anders Götherström; Mark G. Thomas; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; ancient DNA; boat cemeteries; Early Medieval Period; Central Svealand; bone preservation; inheritance; acquired status; inherited status; arkeologi; Archaeology;

    Sammanfattning : This is a study of the role of inheritance among the élite in Early Medieval central Svealand and the possibility to study it by molecular genetic methods. The study is a part of the research project Svealand in the Vendel and Viking periods (SIV). The study rests on classical as well as a new type of source material. LÄS MER

  7. 5. Endometrial carcinoma : prognostic factors and protein expression profiling

    Författare :Caroline Lundgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Endometrial carcinoma; prognosis; DNA ploidy; MIB-1; p53; laminin-5 72 chain; 2DE;

    Sammanfattning : Endometrial carcinoma is the most common gynaecological cancer in the western world. It is usually diagnosed at an early stage since it presents with irregular vaginal bleeding when the tumour is still limited to the uterus and the prognosis is generally favourable. LÄS MER
