  2. 1. Archaeological Genetics - Approaching Human History through DNA Analysis

    Author : Evangelia Daskalaki; Anders Götherström; Mattias Jakobsson; Walther Parson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ancient DNA; pyrosequencing; molecular genetics; aDNA; neolithization; evolutionary genetics; mtDNA; viking age; archaeological genetics; genetik; evolutionsgenetik; naturvetenskap; neolitisering; vikingatid; arkeologisk genetik; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : There are a variety of archaeological questions, which are difficult to assess by traditional archaeological methods. Similarly, there are genetic and population genetic questions about human evolution and migration that are difficult to assess by studying modern day genetic variation. READ MORE

  4. 2. Molecular population genetics of inducible defense genes in Populus tremula

    Author : Carolina Bernhardsson; Stefan Jansson; Santiago González-Martinez; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Populus; herbivore defense; adaptation; population genetics; population structure; association mapping; complex traits; evolutionär genetik; evolutionary genetics;

    Abstract : Plant-herbivore interactions are among the most common of ecological interactions. It is therefore not surprising that plants have evolved multiple mechanisms to defend themselves, using both constitutive chemical and physical barriers and by induced responses which are only expressed after herbivory has occurred.

  5. 3. Evolutionary genetics and consequences of inbreeding in sand lizards (Lacerta agilis)

    Author : Badreddine Bererhi; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Inbreeding; sand lizards; evolutionary genetics;

    Abstract : Inbreeding is a well-known phenomenon in evolutionary and conservation biology. In the 19th century, Charles Darwin demonstrated the detrimental effects of inbreeding in plants, followed by over a century of extensive research including various animal and plant taxa. READ MORE

  6. 4. Domestication Effects on the Stress Response in Chickens : Genetics, Physiology, and Behaviour

    Author : Amir Fallahshahroudi; Per Jensen; Frank Albert; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Animal domestication; stress response; gene expression; QTL; eQTL;

    Abstract : Animal domestication, the process where animals become adapted to living in proximity to humans, is associated with the alteration of multiple traits, including decreased fearfulness and stress response. With an estimated population of 50 billion, the domesticated chicken is the most populous avian species in the world. READ MORE

  7. 5. Uncovering the Past through ancient DNA : The Fate and Legacy of the last hunter-gatherers in Western Europe and Northwestern Africa

    Author : Luciana G. Simões; Mattias Jakobsson; Torsten Günther; Cristina Valdiosera; Emma Svensson; Martin Sikora; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; human evolution; archaeogenomics; ancient DNA; population genetics; hunter-gatherer; Populationsbiologi; Population Biology; Genetik; Genetics;

    Abstract : The genetic analysis of ancient human remains has revolutionized the study of human history, opening a direct window onto the demographic and evolutionary events that shaped our species' past. I use state-of-the-art ancient DNA methodologies, from sample collection and DNA extraction to data analysis, to study the ancient past of the western Mediterranean region, where climate does not favour DNA preservation.
