  1. 1. Sexual Selection and Adaptation to Novel Environments

    Författare :Ivain Martinossi-Allibert; David Berger; Göran Arnqvist; Lukas Schärer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sexual selection; Environmental change; Sexual conflict; Environmental stress; Adaptation; Adaptive landscape; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Sammanfattning : The work included in this thesis aims at exploring the environmental sensitivity of benefits and costs of sexual selection through a combined empirical and theoretical effort, to increase our understanding of the impact of environmental change on sexually reproducing populations.Can sexual selection promote adaptation to novel environments? Sexual selection for good genes should accelerate adaptation by granting higher reproductive success to individuals of high genetic quality. LÄS MER

  2. 2. Hopeful monsters: The role of hybrids in adaptation : The impact of hybridisation and genetic diversity on adaptation to stressful and novel environments

    Författare :Ciaran Gilchrist; Rike Stelkens; Christopher Wheat; Linda Laikre; Mathilde Cordellier; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Experimental evolution; Saccharomyces cerevisiae; population genetics; hybridisation; adaptation; aneuploidy; comparative genomics; evolve-and-resequence; de novo mutations; evolutionary parallelism; populationsgenetik; Population Genetics;

    Sammanfattning : Adaptation to novel environments can only occur if natural selection has the raw material to act upon. But small, endangered populations are often genetically depleted, and the acquisition of beneficial de novo mutations often takes too long when population face quick and extreme environmental change.

  3. 3. Helicobacter pylori : multitalented adaptation of binding properties

    Författare :Sara Henriksson; Thomas Borén; Göran Larson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; adherence; receptor specificity; adaptation; pH; BabA; Leb; recombination; secretor phenotype; recombinant cell lines;

    Sammanfattning : Helicobacter pylori infects and persistently colonizes the stomach, which results in gastritis and in some individuals peptic ulcer disease or gastric cancer. Adherence of H. pylori to the epithelium is an important factor for development of disease. LÄS MER

  4. 4. The Art of Repeating Oneself : Migratory self-adaptation: media transformation and authorship in Persepolis and The Patience Stone

    Författare :Nafiseh Mousavi; Liviu Lutas; Karin Kukkonen; Rossholm Anna Sofia; Moira Inghilleri; Jens Schröter; Jan-Noël Thon; Golnar Nabizadeh; Linnéuniversitetet; []
    Nyckelord :HUMANIORA; HUMANITIES; migration; authorship; migrant author; adaptation; self-adaptation; intermediality; media transformation; mediasphere; border; transfer; translation; translingualism; memory; Comparative literature; Litteraturvetenskap; Franska med litteraturvetenskaplig inriktning; French literature; Film Studies; Filmvetenskap;

    Sammanfattning : This thesis studies the process and products of migratory self-adaptation: the practice of a migrant author recreating their own work in a new medium, and the baggage it brings with itself. Migratory self-adaptation is developed and analyzed in this research through a comparative and processual analysis of two cases of adaptation: Persepolis, a French autobiographical graphic novel written and drawn by Marjane Satrapi, the Franco- Iranian artist and writer, later turned into an animation movie co-written and codirected by Satrapi herself; and The Patience Stone, a novel written in French by Atiq Rahimi, the Franco-Afghan author, which is adapted to a homonymous film in Dari- Persian, co-written and directed by the author.

  5. 5. Influenza Neuraminidase : Novel mechanisms of influenza NA that enable adaptation and promote diversification

    Författare :Hao Wang; Robert Daniels; Colin Russell; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Influenza; IAV; neuraminidase; transmembrane domain; the central Ca2 binding site; heterotetrameric formation; viral incorporation; evolution; adaptation; diversification; Biochemistry; biokemi;

    Sammanfattning : Influenza A viruses (IAVs) are one of the most common human respiratory pathogens and are largely responsible for the seasonal influenza epidemics that cause mild to severe disease. The two IAV glycoproteins, hemagglutinin (HA or H) and neuraminidase (NA or N), serve as the major surface antigens and also are the main determinants of infectivity, pathogenicity and transmissibility.
