  1. 1. Recruitment from resting stages among bloom-forming cyanobacteria

    Författare :Annika Ståhl-Delbanco; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi; marine biology; Hydrobiology; resting stage; Cyanobacteria; recruitment; algal bloom;

    Sammanfattning : Cyanobacteria are known to form heavy blooms in eutrophicated freshwaters and also form resting stages, associated with the sediments, during harsh growth conditions. These resting stages can serve as inoculum for pelagic populations and function as a potential source for bloom formations. LÄS MER

  3. 2. Single cell carbon and nitrogen dynamics in chain forming diatoms, including their resting stage

    Författare :Rickard Stenow; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diatoms; Resting stages; N cycling; Chain formation; Secondary ion mass spectrometry SIMS ;

    Sammanfattning : The oceans are a fundamental part of all life on earth, accounting for more than half of Earth’s oxygen production. The ocean is also key to long term carbon dioxide sequestration. Diatoms are a group of phytoplankton differentiated by their silica shell/frustule and account for ~20% of global primary production.

  4. 3. Survivors of the Sea: Investigating the genomics and survival strategies of the diatom Skeletonema marinoi

    Författare :Matthew I. M. Pinder; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diatoms; Skeletonema marinoi; Resting stages; Bioinformatics; Genomics; Gene expression; Metabarcoding;

    Sammanfattning : Diatoms are an ecologically important group of phytoplankton, responsible for around 20% of global primary production. One of the features contributing to their success is their ability to form resting stages, a response to adverse conditions in which they enter a dormant state and sink to the sediment. LÄS MER

  5. 4. 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

  7. 5. Genetic structuring in natural populations - the influence of life history strategies and asymmetric migration

    Författare :Lisa Sundqvist; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Population genetics; Asymmetric migration; Genetic differentiation; Resting stages; Gene flow; Phytoplankton; Macroalgae;

    Sammanfattning : In this thesis I investigate aspects of genetic differentiation and factors influencing the structure of populations. This is done with a special focus on life histories and dispersal strategies common in the marine environment. LÄS MER
