  1. 6. Genetic diversity and differentiation in natural and managed stands of Norway spruce (Picea abies)

    Författare :Helena Eklöf; Pär K. Ingvarsson; Xiao-Ru Wang; Carolina Bernhardsson; Katri Kärkkäinen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Norway spruce; Picea abies; forestry; genetic diversity; seed orchards; forest management; WGS; GBS; sequencing; PoolSeq; capture probes; genetic differentiation;

    Sammanfattning : Being one of Sweden’s most important tree species, both as a keystone species and for the forest industry, it is important that we keep our stands of Norway spruce (Picea abies (L.) Karst.) as healthy as possible. LÄS MER

  3. 7. Effects of Agriculture on Abundance, Genetic Diversity and Fitness in the Common Frog, Rana temporaria

    Författare :Markus Johansson; Anssi Laurila; Juha Merilä; Craig R. Primmer; Michael W. Bruford; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; agriculture; agrochemicals; amphibians; effective population size; genetic diversity; genetic structure; hierarchical sampling; microsatellites; Rana temporaria; Biologi; Biology; Biologi;

    Sammanfattning : The aims of this thesis were to evaluate the effects of agriculture on amphibians in terms of (i) population genetic consequences of agriculture-induced spatial changes of the landscape and (ii) local adaptation and tolerance to frequently used agrochemicals. The study was performed using the common frog Rana temporaria as a model. LÄS MER

  4. 8. Population Genetic Methods and Applications to Human Genomes

    Författare :Lucie Gattepaille; Mattias Jakobsson; Kevin Thornton; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 9. Fungal disease dynamics, genetic variation and biodiversity-yield relationships : — a study along a gradient of coffee management in southwestern Ethiopia

    Författare :Beyene Zewdie Hailu; Kristoffer Hylander; Ayco J.M Tack; Jacques Avelino; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Armillaria root rot; biodiversity; biodiversity-yield trade-offs; coffee; Coffea arabica; coffee berry disease; coffee leaf rust; coffee wilt disease; coffee yield; genetic composition; genetic diversity; hyperparasite; management intensity gradient; southwestern Ethiopia; Plant Ecology; växtekologi;

    Sammanfattning : Intensification of agricultural systems is a major threat to the associated biodiversity and could also affect the dynamics of pests and pathogens. One such system that is currently under an intensification trajectory is the production of Arabica coffee. LÄS MER

  7. 10. Exploring genetic diversity in natural and domestic populations through next generation sequencing

    Författare :Nima Rafati; Leif Andersson; Carl-Johan Rubin; Alvaro Martinez Bario; Craig Primmer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecological adaptation; seasonal reproduction; Atlantic herring; domestication; speciation; rabbit; skeletal atavism; Shetland ponies; NGS; SMRT sequencing; genome; transcriptome; assembly; structural variation; genetic diversity; HCE; TSHR; SHOX; CRLF2;

    Sammanfattning : Studying genetic diversity in natural and domestic populations is of major importance in evolutionary biology. The recent advent of next generation sequencing (NGS) technologies has dramatically changed the scope of these studies, enabling researchers to study genetic diversity in a whole-genome context.
