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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. Baltic Sea phytoplankton in a changing environment

    Author : Mireia Bertos-Fortis; Catherine Legrand; Ilana Berman-Frank; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phytoplankton ecology; cyanobacteria; dynamics; environmental factors; successional patterns; interactions; life strategies; non-ribosomal peptides; diversity; nodularin; N. spumigena; Akvatisk ekologi; Aquatic Ecology;

    Abstract : Future climate scenarios in the Baltic Sea project increasing sea surface temperature, as well as increasing precipitation and river runoff resulting in decreased salinity. These changes can severely impact the dynamics and function of brackish water communities, specifically phytoplankton. READ MORE

  6. 4. Phytoplankton and bacterioplankton dynamics in a polymictic tropical lake

    Author : Rolf Erikson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; tropical lake; algae; bacteria; regulation; dynamics; interaction; Biologi; Biology; Biologi; limnologi; Limnology;

    Abstract : Phytoplankton and bacterioplankton dynamics in lakes are regulated by a multitude of factors such as light, temperature, water column mixing, nutrients, organic substrates, grazing, and food web structure. Tropical lakes are especially interesting to study because of the relative constancy of several of these factors. READ MORE

  7. 5. Freshwater, density gradients and biological processes in cold, brackish seas : aspects of the biogeophysical fluid dynamics characterising the Baltic Sea

    Author : Tapani Stipa; Peter Haugan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Östersjön; Oceanografi; meteorologi; Meteorology;

    Abstract : The dominant component in the ocean water is freshwater. In this thesis its mixing and the freshwater-induced dynamics are discussed, with cold, brackish basins such as the Baltic Sea especially in mind. A mathematical framework is derived to allow for a consistent way of adding freshwater effects to the governing equations. READ MORE
