  1. 1. Sexual Conflict and Gene Expression in Drosophila melanogaster

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Paolo Innocenti; Uppsala universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sexual conflict; sexual selection; male-female coevolution; gene expression; transcriptome; microarrays; sexual dimorphism; Drosophila; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Sexual conflict is broadly defined as a conflict between the evolutionary interests of the two sexes. Depending on the genetic architecture of the traits involved, it can occur at the level of male-female interactions or take the form of selection acting to change the mean of a shared trait against the sign of its genetic correlation.

  2. 2. Immunogenetic variation along the latitudinal gradient in Scandinavian anuran species Evolutionary processes, demography and infection

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Maria Cortazar-Chinarro; Uppsala universitet.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biologi; Biology; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : The evolutionary and demographic processes affecting how genetic variation is partitioned and distributed over large geographical scales is of fundamental importance for our understanding of how organisms may adapt to their environments. Northern peripheral populations generally have lower genetic variation and individuals in these populations may therefore face difficulties adapting to their local environment. LÄS MER

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Emma Rova; Uppsala universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Callosobruchus maculatus; host fidelity; assortative mating; inbreeding; experimental evidence; sympatric speciation; parapatric speciation; NATURAL SCIENCES Biology; NATURVETENSKAP 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

  4. 4. Spatial Modelling of Coastal Fish – Methods and Applications

    Sammanfattning : Environmental factors influence species and habitats on multiple scales creating a mosaic of distribution patterns. Studying factors shaping these patterns are central to our understanding of population dynamics and ultimately ecosystem functioning. LÄS MER

  5. 5. Sexual conflict, sexual selection, and genetic variance in fitness

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Karl Grieshop; Uppsala universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Sammanfattning : Understanding sex-specific genetic variance for fitness is of fundamental importance to our understanding of evolution. This thesis presents the findings of empirical investigations into sex-specific genetic variance in fitness. LÄS MER
