  2. 1. Evolutionary genomics in Corvids : – From single nucleotides to structural variants

    Author : Matthias H. Weissensteiner; Jochen B.W. Wolf; Manfred Grabherr; Kateryna M. Makova; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; evolutionary genetics; genomics; population genetics; selection; recombination; chromosomal features; colouration; insertion; deletion; inversion; crow; tandem repeat; transposable element; gene expression;

    Abstract : Heritable genetic variation is the raw material of evolution and can occur in many different forms, from altering single nucleotides to rearranging stretches of millions at once. DNA mutations that result in phenotypic differences are the basis upon which natural selection can act, leading to a shift of the frequency of those mutations. READ MORE

  4. 2. Speciation and Metabolic rate : Insights from an avian hybrid zone

    Author : S. Eryn McFarlane; Anna Qvarnström; Jenny Boughman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; resting metabolic rate; life history; hybridization; speciation; reproductive isolation; Ficedula flycatcher; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Abstract : The role of divergent climate adaptation in speciation has received surprisingly little scientific attention. My dissertation research focused on how resting metabolic rate (RMR) relates to the build up of prezygotic and postzygotic isolation in a natural Ficedula flycatcher hybrid zone. READ MORE

  5. 3. Quo vadis? Insights into the determinants of evolutionary dynamics

    Author : Alexandre Rêgo; Rike Stelkens; Dmitri Petrov; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; natural selection; selection; genetic drift; evolutionary rescue; historical contingency; adaptation; complex environments; evolutionary predictability; parallel evolution; populationsgenetik; Population Genetics;

    Abstract : Predicting future evolutionary outcomes and explaining past and current patterns of biodiversity are fundamental goals in evolutionary biology. Trajectories of evolving populations are determined by evolutionary mechanisms (natural selection, mutation, genetic drift, and gene flow) and the environment in which the populations are found.

  6. 4. Population-level consequences of variation

    Author : Lena Wennersten; Anders Forsman; Olof Leimar; Deepa Agashe; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; colour polymorphism; diversity; establishment success; evolutionary changes; population-level consequences; predation risk; Tetrix subulata; variation; Evolutionary Biology; Evolutionsbiologi;

    Abstract : Consequences of within population variation have recently attracted an increased interest in evolutionary ecology research. Theoretical models suggest important population-level consequences, but many of these predictions still remain to be tested. READ MORE

  7. 5. Adaptive divergence in fission yeast : From experimental evolution to evolutionary genomics

    Author : Sergio Ivan Tusso Gomez; Jochen B.W. Wolf; Simone Immler; Roger K. Butlin; Uppsala universitet; []
    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
