  1. 1. The Niches of Bacterial Populations in Productive Waters : Examples from Coastal Waters and Four Eutrophic Lakes

    Författare :Alexander Eiler; Stefan Bertilsson; Lars J. Tranvik; Janet Jansson; Katherine McMahon; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; diversity; 16S rRNA; phytoplankton; bloom; pathogen; carbon cycle; Ekologi;

    Sammanfattning : Recent research in microbial ecology has focused on how aquatic bacterial communities are assembled. Only a few of these studies follow a “Gleasonian” approach where the roles of single bacterial populations are in focus. LÄS MER

  3. 2. Phytoplankton and Physical Disturbance : Seasonal dynamics in temperate Lake Erken, Sweden

    Författare :Yang Yang; Kurt Pettersson; Peeter Nõges; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phytoplankton dynamics; high-frequency measurements; thermal stratification; water column stability; equilibrium; disturbance;

    Sammanfattning : Phytoplankton mirrors changes in the environment and plays an important role in biogeochemical processes. Phytoplankton dynamics is the outcome of both autogenic succession and external disturbances. LÄS MER

  4. 3. Bloom dynamics and population genetics of marine phytoplankton - Community, species and population aspects

    Författare :Karolina Härnström; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phytoplankton; dynamics; Skeletonema marinoi; population genetics; resting stages;

    Sammanfattning : Phytoplankton are the most important primary producers in the world’s oceans and coastal waters, accounting for nearly half of the global net primary production. Although they are such important organisms, little is known about the ecology and dynamics of phytoplankton. LÄS MER

  5. 4. Latest Miocene – Early Pliocene Paleoclimate and Phytoplankton Productivity

    Författare :Boris-Theofanis Karatsolis; Jorijntje Henderiks; Luc Beaufort; Uppsala universitet; []
    Nyckelord :Late Miocene; early Pliocene; IODP; paleoclimate; basin evolution; phytoplankton; paleoproductivity; Milankovitch cycles; Earth Science with specialization in Historical Geology and Palaeontology; Geovetenskap med inriktning mot historisk geologi och paleontologi;

    Sammanfattning : Paper IPre-Quaternary paleoclimate studies in Australia mainly focus on terrestrial records from the southeastern part of the continent. IODP Expedition 356 drilled on the northwestern Australian shelf, yielding Miocene-Pleistocene paleoclimate records in an area where climate archives are scarce. LÄS MER

  7. 5. 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
