  1. 21. Genetic variation in natural populations: a modeller's perspective

    Författare :Marina Rafajlovic; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coalescent process; site frequency spectrum; multiple paternity; dominant clone; divergent selection;

    Sammanfattning : Thanks to advances in genome sequencing, empirical patterns of within- and between-species genetic variation are readily available. By studying these patterns much has been learned about the evolutionary histories of species. But the causes and consequences of different evolutionary histories are still difficult to tell apart.

  3. 22. Feed for defence : can dietary supplements modulate broiler gut microbiota and guard against Campylobacter?

    Författare :Eliska Eliasson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The bacteria Campylobacter jejuni is the causative agent of a disease in humans called campylobacteriosis and is the most commonly reported zoonosis in the European Union, with the primary source of infection often traced to broiler products. While low overall C. LÄS MER

  4. 23. Knowledge Compromise(d)? Ways and values of coproduction in academia

    Författare :Josefine Fischer; Företagsekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; epistemology; knowledge interest; research policy; coproduction; university college;

    Sammanfattning : This thesis deals with the colonisation of the university by market forces. The object of inquiry is coproduction of academic knowledge between academic and non-academic actors in newly established universities and university colleges in Sweden. LÄS MER

  5. 24. Submerged macrophytes in shallow eutrophic lakes - regulating factors and ecosystem effects

    Författare :John A Strand; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; marine biology; Hydrobiology; plasticity; seed banks; periphyton; grazing; alternative stable state; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Sammanfattning : In this thesis I have studied factors that regulate submerged macrophyte abundance, morphology and distribution in shallow eutrophic lakes, and how submerged macrophytes may affect the ecosystem. Light attenuation through the water column (turbidity and water depth) is probably not the most important factor regulating the distribution of submerged vegetation in macrophyte dominated shallow eutrophic lakes, e.

  7. 25. Lactobacilli in the normal microbiota and probiotic effects of Lactobacillus plantarum

    Författare :Elisabeth Lönnermark; Göteborgs universitet; []
    Nyckelord :lactobacillus; oral microbiota; gut microbiota; infants; adults; secretory IgA; IgA-deficiency; adherence; Lactobacillus plantarum; probiotics; antibiotics; salmonellosis; diarrhoea;

    Sammanfattning : Lactobacilli colonise most adult individuals and are also frequently used as probiotics, i.e. bacteria which possibly have health promoting effects when ingested. In this thesis, the intestinal Lactobacillus microbiota was studied in longitudinally followed infants. LÄS MER
