Eco-physiology of phytoplankton - Effects of fluctuating light on photosynthesis and growth of phytoplankton 

Planktonic algae (phytoplankton) are the most important primary producers in many aquatic ecosystems. Phytoplankton development is potentially controlled by light availability, which fluctuates rapidly by wind-induced mixing of the water column. Light-dependency of phytoplankton growth has been traditionally measured under constant light but first studies demonstrated strong effects of light dynamics.

My work contributes to a better understanding of phytoplankton dynamics in well-mixed waters like shallow lakes, rivers and estuaries.

MARS

Our surface and groundwaters struggle with a variety of different pressures, like water shortage, flow regulation, straightening or sediment and nutrient loading. The project MARS analyses how the combination of these stressors impacts aquatic ecosystems and their functions.
