  1. 1. The role of Assortative Mating in the Initial Stages of Sympatric and Parapatric Speciation

    Författare :Emma Rova; Mats Björklund; Göran Arnqvist; James Mallet; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Callosobruchus maculatus; host fidelity; assortative mating; inbreeding; experimental evidence; sympatric speciation; parapatric speciation; Biology; Biologi; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Sammanfattning : Divergence in the face of gene flow is perhaps the most wildly disputed subject among researchers through time. The debate is an old one and we find its origin as far back as the era of Darwin. LÄS MER

  3. 2. Data-driven microscopy: placing high-fidelity data in a population-wide context

    Författare :Oscar André; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Data-driven microscopy; Event-driven microscopy; high-content screening; automation; image analysis; data analysis; cell heterogeneity; host-pathogen interactions; Streptococcus pyogenes GAS ; SARS-CoV-2;

    Sammanfattning : Mikroskopi är idag ett fundamentalt verktyg inom forskning, där det tillåter oss att skåda in och utforska våra prover i hög detalj. Mycket utav utvecklingen av nya mikroskopimetoder har strävat efter att öka den detaljnivå vi kan uppnå. LÄS MER

  4. 3. Factors influencing the evolution of HIV-1

    Författare :Markus Birk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HIV; antiretroviral treatment; evolution; gag; pol; env;

    Sammanfattning : Due to the high replication rate and the low fidelity of the viral reverse transcriptase (RT), various mutations are introduced continuously into the gene pool of HIV-1. Together with recombination events this leads to the evolution of countless quasispecies. LÄS MER

  5. 4. iLocks: a novel tool for RNA assays with improved specificity

    Författare :Tomasz Krzywkowski; Mats Nilsson; Gunnar von Heijne; Weng-Onn Lui; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RNA; miRNA; non-coding RNA; padlock probes; rolling circle amplification; invader; single cell; in situ; adenovirus; virology; diagnostics; Biochemistry; biokemi;

    Sammanfattning : The Central Dogma of molecular biology describes a framework for how genetic information is transferred in cells, placing RNA as a messenger between DNA and translated proteins. During the last years, interest in RNA research has grown tremendously due to the increasing understanding and recognition of the importance of RNA in regulation of gene expression, biochemical catalysis, and genome integrity surveillance.

  7. 5. Consequences of Environmental Variation for Fish and Their Skin Associated Microbial Communities

    Författare :Hanna Berggren; Anders Forsman; Per Larsson; Mark Dopson; Jarone Pinhassi; Richard Svanbäck; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi;

    Sammanfattning : Environmental conditions that vary in space and time influence the distribution, abundance, diversity and evolution of individuals, populations, species and communities. This thesis explores how environmental variation affects diversity at different levels of biological organization, and across a wide range of spatiotemporal scales, by studying fish and their associated microbiomes.
