  2. 1. Factors Affecting the Distribution of Rocky-Shore Macroalgae on the Swedish Coast : Morphological, Physiological, Reproductive and Genetic Aspects

    Author : Gustav Johansson; John Raven; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Abstract : The aim of this thesis was to examine factors affecting the distribution of macroalgal species both vertically (depth zonation) and geographically along the Baltic Sea salinity gradient. Interactions between the physical environment and basic biological traits of the algae are emphasised. READ MORE

  5. 3. An insight towards food-related microbial sets through metabolic modelling and functional analysis

    Author : Simonas Marcisauskas; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; RAVEN; gut; systems biology; comparative genomics; Kluyveromyces marxianus; bile acids; genome-scale metabolic model; next-generation sequencing; transcriptomics; thermotolerance;

    Abstract : The dietary food digestion depends on the human gastrointestinal tract, where host cells and gut microbes mutually interact. This interplay may also mediate host metabolism, as shown by microbial-derived secondary bile acids, needed for receptor signalling. Microbes are also crucial in the production of fermented foods, such as wine and dairy. READ MORE

  6. 4. Neuropsychiatric and neurodevelopmental disorders in a young school-age population. Epidemiology and comorbidity in a school health perspective

    Abstract : A total population of 826 7-year old children attended schools in Karlstad, a middle-sized town in central Sweden in August of 1992. Of these, 818 attended mainstream classrooms. READ MORE

  7. 5. Behaviour and life-history responses to chick provisioning under risk of nest predation

    Author : Sönke Eggers; David Winkler; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Chick provisioning; clutch size; delayed dispersal; nest concealment; nest predation; parental care; population decline; Perisoreus infaustus; Siberian jay; Biologi; Biology; Biologi; populationsbiologi; Population Biology;

    Abstract : This thesis examines risk management in breeding Siberian jays (Perisoreus infaustus), which is indigenous to the northern taiga. Parent behaviour and the nest are cryptic. A new nest is built each year. It is placed on spruce or pine branches close to the trunk and well insulated with lichens, feathers and reindeer hair. READ MORE
