Phytoplankton Ecology

Our research addresses mechanisms and consequences of phytoplankton biodiversity changes in coastal and open seas. Using a variety of approaches including time series analyses of monitoring data, physiological experiments with cultured phytoplankton isolates, analyses of intraspecific genetic and phenotypic diversity and resurrection of past populations from resting stages in “sediment archives”, we investigate the response of phytoplankton communities and populations to environmental change.  The data is used in ecosystem models projecting phytoplankton changes under different scenarios of future environmental conditions and assessing phytoplankton driven ecosystem functions.
