  1. 16. Phenotypic and Genotypic responses in the planktonic diatom Skeletonema marinoi - Effects of Natural Processes and Anthropogenic Stressors

    Författare :Susanna Gross; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diatoms; genotype; phenotype; resting cell; eutrophication; spring bloom; diversity; grazing; adaptation; phytoplankton; microalgae; Skeletonema;

    Sammanfattning : Diatoms are one of the most diverse and abundant phytoplankton taxa and are highly important as primary producers, accounting for nearly half of the marine primary production and constituting the base in the marine food web. Despite their high dispersal potential they are genetically diverse and display genetically structured populations. LÄS MER

  3. 17. Crossing barriers: Genetic consequences of translocating wild cleaner fish for aquaculture

    Författare :Ellika Faust; Göteborgs universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; conservation genetics; population genetics; aquaculture escapee; hybridisation; corkwing wrasse; lumpfish; cleaner fish translocation; sea lice; range expansion; fishery management;

    Sammanfattning : Several species of fish show a symbiotic cleaning behaviour, where they assist other species by feeding and removing dead skin or ectoparasites. Some of these cleaner fish species are used as a low-cost parasite control in salmon aquaculture, often considered to be more environmentally friendly than other delousing methods. LÄS MER

  4. 18. Diversity and functional potential of fungal communities in Arctic and boreal freshwaters

    Författare :Mariana Kluge; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Fungi are important decomposers of the organic matter (OM) in terrestrial environments, but there is limited knowledge about their ecological roles in aquatic ecosystems. This thesis applies a variety of molecular techniques (e.g. LÄS MER

  5. 19. Exploring the microbiota of the gastrointestinal tract

    Författare :Jie Xu; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiota; Probiotics; Blood pressure; High fat diet; Oat; Green tea; Berry; Fiber; Exopolysaccharides; Ulcerative colitis;

    Sammanfattning : Abstract: Balanced microbiota of the gastrointestinal (GI) tract is important for maintaining health of the host. Altered gut microbiota have been found to be associated with various life-style induced and other intestinal inflammatory diseases. Gut microbiota is viewed as a metabolic organ and considered as new target for therapies. LÄS MER

  7. 20. Genetic diversity and nutritional content of sorghum [Sorghum bicolor (L.) Moench] accessions from Southern Africa

    Författare :Tiny Motlhaodi; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Sorghum [Sorghum bicolor (L.) Moench] is an important cereal crop in semi-arid regions of the world especially in Africa, South Asia and China. It is an important food and fodder crop in the semi-arid tropics (SAT) of Africa, where it is used for making different kinds of food. LÄS MER
