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

    Författare :Maria Cortazar-Chinarro; Jacob Höglund; Anssi Laurila; Yvonne Meyer-Lucht; Helena Westerdahl; Uppsala universitet; []
    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. 2. Inferring Evolutionary Processes of Humans

    Författare :Sen Li; Mattias Jakobsson; Ludovic Orlando; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Approximate Bayesian Computation; TMRCA; demography; human evolution; Bantu-Expansion; Out-of-Africa;

    Sammanfattning : More and more human genomic data has become available in recent years by the improvement of DNA sequencing technologies. These data provide abundant genetic variation information which is an important resource to help us to understand the evolutionary history of humans. LÄS MER

  4. 3. Evolutionary innovation : Early industrial uses of genetic engineering

    Författare :Maureen McKelvey; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Biotechnology industry; Economics of innovation; Evolutionary Economics; Genentech; human growth hormone; Kabi; technological innovation; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Based on an analysis of biological and economic theories of evol~tion, this dissertation first specifies evolutionary innovation and then uses it toanalyze early industrial uses of genetic engineering. Innovation refers totechnological innovation processes, i.e. series of innovative activitiesresulting in technical change. LÄS MER

  5. 4. Evolutionary Approaches to Sequence Alignment

    Författare :Marcin Bogusz; Simon Whelan; Jeffrey Thorne; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular evolution; multiple sequence alignment; pair hidden Markov models; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Molecular evolutionary biology allows us to look into the past by analyzing sequences of amino acids or nucleotides. These analyses can be very complex, often involving advanced statistical models of sequence evolution to construct phylogenetic trees, study the patterns of natural selection and perform a number of other evolutionary studies.

  7. 5. Eco-evolutionary processes and community patterns--- novel avenues for studying biodiversity across spatial and temporal scales

    Författare :Yun-Ting Jang; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Eco-evolutionary dynamics; Community diversity patterns; Spatial phylogenetic patterns; Adaptive dynamics; Elevational diversity gradients; Theoretical ecology; Simulation models; Predation; Competition;

    Sammanfattning : Understanding biodiversity patterns poses a persistent challenge due to the complex interconnections of ecological and evolutionary processes. The particular difficulty comes from the various processes influencing biodiversity patterns across different spatial scales. LÄS MER
