  1. 1. Fuel and fly: adaptations to endurance exercise in migrating birds

    Författare :Anders Kvist; Bröstcancer-genetik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water balance; flight power; phenotypic flexibility; energy assimilation; basal metabolism; Animal ecology; Djurekologi;

    Sammanfattning : Birds on migration alternate between consuming fuel stores during flights and accumulating fuel stores during stopovers. This thesis highlights some of the ways in which migrating birds have adapted to the different demands of fuelling and flight. Most of the time on migration is spent at stopover sites accumulating fuel stores. LÄS MER

  3. 2. Phenotypic and social effects on behavioural trade-offs in Eurasian perch

    Författare :Gustav Hellström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Trading between conflicting demands is a fundamental part in how animals interact with its environment and social surrounding. Knowledge of what factors that are affecting behavioural decisions is central in our understanding of animal adaptation and ecology. LÄS MER

    Sammanfattning : Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer in the Nordic countries. Recent evidence indicate that DNA methylation (DNAm) play a central role in the development and progression of the disease. LÄS MER

  5. 4. Evolutionary ecology of arctic char (Salvelinus alpinus (L.)) : Intra- and interspecific interactions in circumpolar populations

    Författare :Johan Hammar; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Arctic char; Salvelinus alpinus; biogeography; niche; life history; population ecology; intra- and interspecific interactions; cannibalism; competition; landlocked; marginal populations; species border; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Animal Ecology; zooekologi;

    Sammanfattning : This thesis examines a suite of ecological and genetic mechanisms influencing the fundamental and realized niche borders of European and North American populations of the Arctic char (Salvelinus alpinus (L.)) species complex in allopatry as well as in sympatry with brown trout (Salmo trutta) or brook trout (Salvelinus fontinalis).

  7. 5. Hfq- and sRNA-mediated regulation in Neisseria meningitidis

    Författare :Jens Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neisseria meningitidis, also known as the meningococcus, is a human-specific pathogen that commonly colonises the nasopharynx without causing disease. For reasons unknown, N. meningitidis can traverse the nasopharyngeal epithelium and enter the bloodstream, causing invasive meningococcal disease manifesting in septicaemia and/or meningitis. LÄS MER
