1. Ecological implications of the production of toxic substances by fish killing phytoplankton species grown under variable N:P-ratios
Sammanfattning : The influence of different nutrient conditions on the production of toxins was studied in certain fishkilling haptophytes (e.g. Prymnesium parvum and Chrysochromulina polylepis). LÄS MER
2. Phytoplankton of Baltic environmental gradients : observations on potentially toxic species
Sammanfattning : .... LÄS MER
3. Phytoplankton response to a changing climate in lakes in northern Sweden
Sammanfattning : In a climate change perspective, increased air temperatures are already a reality and are expected to increase even more in the future, especially in areas at high latitudes. The present thesis therefore addresses the influence of climate change on the physical properties and the phytoplankton communities of typical small and oligotrophic lakes in northern Sweden (62-64˚N).

4. Effects of toxin-producing phytoplankton on copepods: feeding, reproduction and implications to the fate of toxins
Sammanfattning : Phytoplankton growth and loss rates are governed by several factors and in many cases, when growth control fails, algal blooms are established. Such blooms can be formed by different phytoplankton species and some of them have harmful impacts on marine ecosystems. LÄS MER
5. Baltic Sea phytoplankton in a changing environment
Sammanfattning : 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. LÄS MER
