  1. 21. Genomic dynamics over contemporary time frames in wild salmonid populations

    Författare :Sara Kurland; Linda Laikre; Kathryn Elmer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conservation genomics; genetic monitoring; whole-genome sequencing; metapopulation; salmonid; brown trout; effective population size; Pool-seq; genetic connectivity; intraspecific diversity; sympatric populations; populationsgenetik; Population Genetics;

    Sammanfattning : Genetic diversity is the foundation of all biological variation. An approach for sustainable use and protection of genetic diversity is continuous sampling over space and time, i.e. monitoring. LÄS MER

  3. 22. Genetic variation and prostate cancer : population-based association studies in Sweden

    Författare :Sara Lindström; Henrik Grönberg; Fredrik Wiklund; John Todd; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; epidemiology; SRD5A2; ERG; progression; genetics; association studies; polymorphism; haplotype; CDH1; AR; CYP17; Oncology; Onkologi;

    Sammanfattning : Prostate cancer constitutes the most common malignancy and the most common cause of cancer‐related death in Swedish men. A large body of evidence suggests that inherited genetic variants contribute to both development and progression of prostate cancer. LÄS MER

  4. 23. European Black Grouse : MHC Genetic Diversity and Population Structure

    Författare :Tanja Strand; Jacob Höglund; Helena Westerdahl; David S. Richardson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Major Histocompatibility Complex; BLB; balancing selection; concerted evolution; bottleneck; fragmentation; 3 UTR; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Sammanfattning : Black grouse Tetrao tetrix is a bird species composed of large, continuous as well as severely reduced and fragmented populations, making it an optimal species to investigate how genetic diversity is affected by habitat fragmentation. I have focused on genetic diversity in the Major Histocompatibility Complex (MHC) to measure the ability of the black grouse to respond to environmental changes. LÄS MER

  5. 24. Genetic aspects of stroke : association and linkage studies in a northern Swedish population

    Författare :Per-Gunnar Wiklund; Birgitta Stegmayr; Kjell Asplund; Dan Holmberg; Alun Evans; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Internal medicine; stroke; genetics; polymorphism; association; linkage; risk factors; plasminogen activator inhibitor-1; tissue plasminogen activator; angiotensin converting enzyme; angiotensin II receptor type 1; phosphodiesterase 4D; Invärtesmedicin; Internal medicine; Invärtesmedicin; medicin; Medicine;

    Sammanfattning : Stroke is a common, multifactorial cardiovascular disease. A stroke event is the result of traditional risk factors (i.e. hypertension, diabetes, smoking), environmental exposures and genetic factors in a complex interplay. LÄS MER

  7. 25. Assessing and monitoring genetic patterns for conservation purposes with special emphasis on Scandinavia

    Författare :Anna Palmé; Nils Ryman; Linda Laikre; Kerry Naish; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biological diversity; conservation genetics; management unit; spatial genetic structure; sympatric populations; genetic monitoring; release of alien populations; northern pike; brown trout; harbour porpoise; Biology; Biologi; populationsgenetik; Population Genetics;

    Sammanfattning : Genetic variation is essential for biological evolution, for maintaining viability of populations, and to ensure ecosystem resilience. Increased human exploitation and environmental change result in rapid loss of biological variation, including genetic diversity. LÄS MER
