Chemically Mediated Interactions in the Plankton
Numerous interactions within the plankton are controlled by chemical signals. We address this regulation combining methods and concepts from chemistry, microbiology and ecology.
A key to success in these projects is the work with the organisms in experiments allowing to monitor performance in ecological interaction situations. We rely on co-culturing methods for simple investigations of interactions and expand the approach to work in plankton enclosures (mesocosms). Experiments with natural communities in the open oceans during research cruises or field stays round up the concept and provide the ultimate proof for the validity of the lab generated hypotheses.
Projects within this research focus include
- the investigation of polar zwitterionic metabolites produced and released by algae in amounts sufficient to influence global climate processes. Thume et al. Nature 2018https://www.nature.com/articles/s41586-018-0675-0
- the control of algal blooms by bacterial infections https://academic.oup.com/femsre/article/41/6/880/4091024
- the elucidation of mechanisms of viral infection of phytoplankton blooms. Here infection processes of the globally important alga Emiliania huxleyi are monitored using ecological, metabolomic and proteomic methods. Rosenwasser et al. Plant Cell http://www.plantcell.org/content/26/6/2689
