  1. 6. Conservation genomics in inbred Scandinavian wolves using bioinformatic methods

    Författare :Linnéa Smeds; Hans Ellegren; Giorgio Bertorelle; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; conservation genomics; Canis lupus; bioinformatics; Y chromosome; admixture; genetic load; structural variation; GWAS; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : With the recent and unprecedented progress in retrieving DNA sequence information from a large number of individuals of any species, conservation genetic research has entered a new phase. Specifically, it has become possible to study how genomes of endangered species respond to reductions in population size. LÄS MER

  3. 7. Leaching of Hazardous Substances from Concrete Constituents and Painted Wood Panels

    Författare :Åse Togerö; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thiocyanate; biocides; leaching; runoff; admixture; coatings; resin acids; blast furnace slag; toxic; fly ash; cement; tall oil; diffusion paints; concrete;

    Sammanfattning : At a time of increased concern about environmental issues in the building sector, it is essential to know the environmental performance of different building materials. Knowledge of the possible release of hazardous substances in building materials is scarce, and these aspects have often been neglected in environmental assessment methods. LÄS MER

  4. 8. Divergence, admixture and continuity in the human past : Demographic inference using ancient and modern genomes

    Författare :James McKenna; Mattias Jakobsson; Per Sjödin; Ida Moltke; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Human evolution; population genetics; ancient genomes; population continuity; divergence; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Sammanfattning : Demographic forces shaping the genetic variation we observe today can include population divergences, admixture events and continuity through time. The advancement of high-throughput sequencing technologies, together with developments in molecular and bio-informatics methods, mean the number of ancient genomes available for inference has risen steeply.

  5. 9. Ecological drivers and genetic signatures of evolutionary divergence and local adaptation in pike (Esox lucius)

    Författare :Johanna Sunde; Anders Forsman; Anssi Laurila; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; adaptation; differentiation; Esox lucius; evolution; gene flow; genetic admixture; genetic structure; microsatellites; pike; RADseq; salinity tolerance; temperature tolerance; Ecology; Ekologi;

    Sammanfattning : The diversity among species, populations, and individuals in nature is astonishing. Genetic and phenotypic variation constitutes the raw material for evolution. It influences how populations respond to changing environments, and can impact long-term survival of species and ecosystem functioning. LÄS MER

  7. 10. Demographic History and Adaptation in African Populations

    Författare :Mário Vicente; Carina Schlebusch; Mattias Jakobsson; Lluis Quintana-Murci; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; African demography; human evolutionary genetics; population structure; population admixture; genetic adaptation;

    Sammanfattning : Africa is the continent where modern humans originated and yet, African demographic history remains largely unknown. Through analyzing the genetic composition of extant and extinct individuals, it is possible to reveal signals of past demographic history and adaptation. LÄS MER
