  1. 1. Adaptive divergence in fission yeast From experimental evolution to evolutionary genomics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sergio Ivan Tusso Gomez; Jochen B.W. Wolf; Simone Immler; Roger K. Butlin; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; adaptation; divergence; selection; experimental evolution; genomics; genome evolution; population genetics; fission yeast; phenotypic variation; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : How adaptation and population differentiation occur is fundamental to understand the origin of biodiversity. Work in speciation alongside the increased ease of generating genomic data have allowed the exploration of genomic changes relevant to adaptation. READ MORE

  2. 2. Population Genetic Methods and Applications to Human Genomes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lucie Gattepaille; Mattias Jakobsson; Kevin Thornton; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Population genetics; Human evolution; Genetic diversity; Genetic differentiation; Adaptation; Population structure; Effective population size; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Population Genetics has led to countless numbers of fruitful studies of evolution, due to its abilities for prediction and description of the most important evolutionary processes such as mutation, genetic drift and selection. The field is still growing today, with new methods and models being developed to answer questions of evolutionary relevance and to lift the veil on the past of all life forms. READ MORE

  3. 3. Postmating Sexual Selection and its Role in Population Divergence in Beetles

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Claudia Fricke; Göran Arnqvist; David Hosken; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Callosobruchus maculatus; postmating sexual selection; speciation; laboratory selection experiment; divergence; Biologi; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi;

    Abstract : Speciation is the process describing the formation of new species and is at the heart of evolutionary biology. According to the biological species concept only reproductively isolated forms are regarded good species. This thesis aims at identifying evolutionary processes that cause population divergence and, ultimately, speciation. READ MORE

  4. 4. Population divergence at small spatial scales – theoretical and empirical investigations in perch

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sara Bergek; Mats Björklund; Teija Aho; Sarah Goodacre; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Perca fluviatilis L.; Perch; Small scale genetic differentiation; Morphometrics; Isolation by distance; Dispersal; Gene flow; Microsatellites; Spatiotemporal stability; Barriers; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi Terrestrisk; limnisk och marin ekologi; Animal Ecology; zooekologi;

    Abstract : Genetically structured populations arise when gene flow between groups of individuals is hindered by geographical, behavioural or temporal barriers. The identification of such groups is important for understanding evolution and has large implications for conservation concern. READ MORE

  5. 5. Ontogeny and Population Biology of a Sex-Limited Colour Polymorphism

    University dissertation from Xanto Grafiska AB

    Author : Jessica Abbott; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; embryologi; ontogeni; animal morphology; embryology; Utvecklingsbiologi; Damselflies; Colour polymorphism; Development; Frequency-dependence; Morphology; growth animal ; ontogeny; Animal anatomy; Development biology; Djurs anatomi och morfologi; Population divergence; Animal ecology; Djurekologi;

    Abstract : This study has involved investigation of number of populations of the damselfly Ischnura elegans over several years, looking at frequency changes over time, morphological differences between the sexes and the morphs, differences in growth rate and development time, differences in fecundity between the morphs, and genetic differentiation between populations.
