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.
