    Sammanfattning : Glucose-6-phosphatase (G6pase) is a multi-component enzyme system, which regulates the catalysis of gluco se-6 -phosphate (G6P) to glucose and inorganic phosphate. This reaction constitutes the final steps of both gluconeogenesis and glycogenolysis, processes that are critical in the maintenance of glucose homeostasis. LÄS MER

  2. 2. To Bee or Not to Be : Critical Floral Resources of Wild-Bees

    Författare :Magnus Larsson; Anders L Nilsson; Jon Ågren; Björn Cederberg; James H Cane; Uppsala universitet; []
    Nyckelord :Ecology; Andrena hattorfiana; Andrena marginata; Andrenidae; Knautia arvensis; limitation; oligolecty; pollen; pollination; solitary bee; specialist bee; Succisa pratensis; Ekologi;

    Sammanfattning : In recent decades, the development of strategies to prevent or slow the loss of biodiversity has become an important task for ecologists. In most terrestrial ecosystems wild-bees play a key role as pollinators of herbs, shrubs and trees. The scope of this thesis was to study 1) pollinator effectiveness of specialist bees vs. LÄS MER

  3. 3. Insect Diversity in Changing Landscapes

    Författare :Markus Franzén; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; växtparasitologi; Entomologi; plant parasitology; Zoology; Zoologi; Entomology; Ekologi; Ecology; butterfly; bee; dispersal; extinction; Djurekologi; Animal ecology;

    Sammanfattning : During recent decades, concern about the loss of biodiversity has increased. To change this negative trend there is an urgent need for effective conservation measures and there are ample evidence that conservation of organisms without an understanding of their ecology and behaviour is impossible.

  4. 4. Genome evolution of a bee-associated bacterium

    Författare :Andrea García-Montaner; Siv Andersson; Matthias Horn; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bacterial evolution; Genomics; Symbiosis; Honeybees; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : The use of large-scale comparative genomics allows us to explore the genetic diversity and mechanisms of evolution of related organisms. This thesis has focused on the application of such approaches to study Lactobacillus kunkeei, a bacterial inhabitant of the honeybee gut.We produced 102 novel complete genomes from L. LÄS MER
