  1. 6. Magnesium Chelatase - a Key Enzyme in Chlorophyll Biosynthesis

    Författare :Eva Axelsson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; AAA-proteins; Chlorophyll biosynthesis; Magnesium chelatase;

    Sammanfattning : The biosynthesis of chlorophylls is an important process in nature. The green pigments play a fundamental role in absorbing and transferring solar energy to the photosynthetic apparatus. LÄS MER

  2. 7. Peatland Bryophytes in a Changing Environment : Ecophysiological Traits and Ecosystem Function

    Författare :Gustaf Granath; Håkan Rydin; Joachim Strengbom; Steven K Rice; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; allometric scaling; chlorophyll fluorescence; competition; decomposition; flooding; mire; N concentration; nitrogen deposition; photosynthesis; succession; stoichiometry; Ecological Botany; Ekologisk botanik;

    Sammanfattning : Peatlands are peat forming ecosystems in which not fully decomposed plant material builds up the soil. The sequestration of carbon into peat is mainly associated with the bryophyte genus Sphagnum (peat mosses), which dominate and literally form most peatlands. LÄS MER

  3. 8. Protein complexes in chlorophyll biosynthetic enzymes

    Författare :Ragna Peterson Wulff; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron microscopy; mass spectrometry; Rhodobacter capsulatus; barley; cyclase; magnesium chelatase; chlorophyll biosynthetic pathway; Protein complex;

    Sammanfattning : Proteins are found on the inside, in the membrane, on the surface and on the outside of cells. They form complicated structures and they interact with other molecules and proteins. LÄS MER

  4. 9. The role of Southern Ocean fronts in the global climate system

    Författare :Robert M. Graham; Agatha de Boer; Alberto Naveira Garabato; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Southern Ocean; fronts; jets; Antarctic Circumpolar Current; wind stress; chlorophyll; iron; Last Glacial Maximum; Marine Geology; maringeologi;

    Sammanfattning : The location of fronts has a direct influence on both the physical and biological processes in the Southern Ocean. However, until recently fronts have been poorly resolved by available data and climate models. LÄS MER

  5. 10. Bio-optics, satellite remote sensing and Baltic Sea ecosystems : Applications for monitoring and management

    Författare :Therese Harvey; Susanne Kratzer; Jakob Walve; Petra Philipson; Stiig Markager; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bio-optics; Remote sensing; MERIS; Eutrophication; Baltic Sea; Monitoring; Management; WFD; MSFD; HELCOM; Chlorophyll-a; Secchi depth; Coloured Dissolved Organic Matter; Suspended Particulate Matter; Marine Ecology; marin ekologi;

    Sammanfattning : Earth observation satellites cover large areas with frequent temporal repetition and provide us with new insight into ocean and coastal processes. Ocean colour measurements from satellite remote sensing are linked to the bio-optics, which refers to the light interactions with living organisms and dissolved and suspended constituents in the aquatic environment.
