  1. 36. Genetic response to pollution in sticklebacks; natural selection in the wild

    Författare :Emma Lind; Mats Grahn; Marjorie Oleksiak; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Population genomics; genome scan; divergent selection; Gasterosteus aculeatus; Baltic Sea; pollution; funktionell zoomorfologi; Functional Zoomorphology;

    Sammanfattning : The last century, humans have been altering almost all natural environments at an accelerating rate, including the Baltic Sea that has highly eutrophicated areas and many coastal industries such as Pulp-mills. For animals living in a habitat that changes there are basically two alternatives, either to cope with the change or become locally extinct. LÄS MER

  3. 37. 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

  4. 38. Genetic Variation and Migration of Waders

    Författare :Liv Wennerberg; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mtDNA sequencing; microsatellite analysis; Dunlin; Calidris alpina; Curlew Sandpiper; Calidris ferruginea; White-rumped Sandpiper; Calidris fuscicollis; carbon isotope ratios; Zoologi; Zoology; Ecology; bird migration; population genetics; Ekologi; Animal ecology; Djurekologi;

    Sammanfattning : The migratory behaviour of birds has received much scientific interest, though many questions still remain unsolved. One of the reasons for this is the difficulty of following the birds as they move between breeding and wintering localities. Populations may mix on migration and the origin of individual birds is difficult to assess. LÄS MER

  5. 39. Finding Genes for Schizophrenia

    Författare :Karolina Åberg; Elena Jazin; Eva Lindholm; Eric Sobel; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; psychiatric genetics; QKI; large pedigree; haplotype investigation; mRNAexpression; genetic linkage; myelin; HTR2C; Biology; Biologi;

    Sammanfattning : Schizophrenia is one of our most common psychiatric diseases. It severely affects all aspects of psychological functions and results in loss of contact with reality. No cure exists and the treatments available today produce only partial relief for disease symptoms. LÄS MER

  7. 40. Gene mapping of reproduction traits in dairy cattle

    Författare :Johanna Karolina Höglund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : In this thesis my aims were to map genes affecting reproduction in cattle and to explore the correlated effect of these genes on yield traits. This knowledge is expected to provide novel insights into the biological processes underlying reproduction traits and to identify individual causal polymorphisms or genetic markers for practical application in marker-assisted and genomic selection strategies.
