   Sammanfattning : This thesis aims to study and describe the ancient populations of grey and harp seals in the Baltic Sea, and to present new methodological approaches for general use in ancient DNA studies.The dissertation is comprised of five studies: a review of the use of paleogenetics in studying ancient human-marine mammal interactions; a method paper investigating patterns of DNA preservation in ancient pinniped samples; a method paper presenting a genetic sex identification method for ancient pinnipeds; a population genomic study of the Baltic grey seal; and a population genomic study of the now extinct Baltic harp seal.

3. 2. Gene technology at stake : Swedish governmental commissions on the border of science and politics

   Författare :Jenny Eklöf; Kjell Jonsson; Christer Nordlund; Susanne Lundin; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Gene technology; biotechnology; recombinant DNA technology; bioethics; ethics; risk; GMO; embryo; transgenic organisms; boundary organization; boundary object; governmental commission; regulatory policy; Sweden; public; expertise; democracy; History of science and ideas; Idé- o lärdomshistoria;

   Sammanfattning : This thesis examines the Swedish political response to the challenges posed by gene technology, seen through the prism of governmental commissions. It discerns and analyses continuities and changes in the Swedish political conception of gene technology, over the course of two decades, 1980–2000. LÄS MER

4. 3. From Fossil To Fact : The Denisova Discovery as Science in Action

   Författare :Mattis Karlsson; Eva Hemmungs Wirtén; Martin Fredriksson; Andreas Nyblom; Staffan Bergwik; Linköpings universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; Actor network theory; aDNA; ANT; Denisovan; Denisova human; Denisova hominin; DNA; Knowledge; Bruno Latour; Science; Science in action; STS; Wikipedia;

   Sammanfattning : From Fossil to Fact: The Denisova Discovery as Science in Action is a study of the (actor) networked relations that make and shape science through the case of the discovery of the Denisova human.In 2010, Nature published the article “The complete mitochondrial DNA genome of an unknown hominin from southern Siberia”, the article revealed the results of mtDNA sequencing of a fossilised finger bone excavated from the Denisova Cave in Siberia, showing that the fossil belonged to an individual of a previously unknown type of humans, the Denisovans.

7. 5. Population History and Non-invasive Monitoring : Use of low copy number DNA in Conservation Genetics

   Författare :Øystein Flagstad; Ettore Randi; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; genetic tagging; immigration; loss of genetic variability; non-invasive molecular techniques; population decline; Swayne’s hartebeest; wolf; wolverine; Biologi; Biology; Biologi; ekologisk botanik; Ecological Botany;

   Sammanfattning : Conservation genetics research is increasingly becoming an integrated part of the management of small and endangered populations. In this thesis I developed tools for genetic analysis of low copy number sources of DNA, such as old teeth from museum specimens as well as field-collected faeces and urine. LÄS MER
