  1. 16. Distribution and modulatory roles of neuropeptides and neurotransmitters in the Drosophila brain

    Författare :Lily Kahsai Tesfai; Åsa M. E. Winther; Ronald Strauss; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; central complex; locomotor behavior; co-transmitter; metabotropic receptor; metabolic stress; Neurobiology; Neurobiologi; zoologi; Zoology;

    Sammanfattning : The central complex is a prominent neuropil found in the middle of the insect brain. It is considered as a higher center for motor control and information processing. LÄS MER

  3. 17. Regulation of metabolic events during embryo development in Norway spruce (Picea abies L. Karst)

    Författare :Edward Businge; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The overall aim of this thesis was to identify and characterize metabolic and biochemical events that are involved in regulation of embryo development in Norway spruce. Embryogenesis involves coordination of multicellular patterning events which are critical for establishment of the apical-basal plan of the plant. LÄS MER

  4. 18. Plant responses after drainage and restoration in rich fens

    Författare :Kalle Mälson; Håkan Rydin; Sebastian Sundberg; Harri Vasander; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ecology; brown mosses; bryophytes; colonization; competition; dispersal limitation; liming; mire; peatland; rewetting; wetland restoration; Ekologi;

    Sammanfattning : Rich fens are an important, but threatened, habitat type in the boreal landscape. In this thesis I have examined responses of rich fen vascular plants and bryophytes after drainage and restoration.The effects of drainage on the rich fen flora were observed in a long time study and the responses were rapid and drastic.

  5. 19. Mosquitoes as a Part of Wetland Biodiversity

    Författare :Martina Schäfer; Jacob Höglund; Jan Lundström; Darold Batzer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; diversity patterns; species assemblages; functional groups; constructed wetlands; dytiscids; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : Wetlands contain both aquatic and terrestrial environments which generates high biodiversity. However, they are commonly associated with mosquitoes (Diptera: Culicidae), and mosquitoes are usually regarded as negative by humans because they can cause nuisance and transmit diseases. LÄS MER

  7. 20. Effects of Dehydration and Blockade of the Renin-Angiotensin System in the One-humped Camel (Camelus dromedarius)

    Författare :Mahmoud Al Haj; Fred Nyberg; Santi Spampinato; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood; biochemical analysis; catecholamine; colorimetric assay; cortisol; dehydration; dromedary camel; glutathione; hematological analysis; HPLC; insulin- like growth factor-1; losartan; plasma; receptors; radioimmunoassay; serum; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : The one-humped or the dromedarian camel is a pseudo-ruminant mammal, well adapted to the hot and dry climates of the desert. Its ability to withstand torrid heat and extreme desiccation is of paramount importance to its survival. LÄS MER
