2. 1. Phenotypic and Genotypic responses in the planktonic diatom Skeletonema marinoi - Effects of Natural Processes and Anthropogenic Stressors

   Author : Susanna Gross; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; diatoms; genotype; phenotype; resting cell; eutrophication; spring bloom; diversity; grazing; adaptation; phytoplankton; microalgae; Skeletonema;

   Abstract : 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. READ MORE

4. 2. 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

5. 3. 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

6. 4. Phytoplankton drivers in a marine system influenced by allochthonous organic matter – the Baltic Sea

   Author : Joanna Paczkowska; Agneta Andersson; Owen Rowe; Harri Kuosa; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; phytoplankton; nutrients; allochthonous organic matter; humic substances; structuring factors;

   Abstract : Climate change scenarios predict that seawater temperature and precipitation will increase in the Baltic Sea region during the next century. In the northern part of the Baltic Sea, increasing inflows of the terrestrial allochthonous dissolved organic matter (ADOM) are expected to be a major consequence of elevated rainfall, which can alter light and nutrient availability for phytoplankton.

7. 5. 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
