Dinoflagellate cyst ecology
To obtain information about the (palaeo-)ecology of cyst forming dinoflagellates the following research activities are carried out:
Culturing dinoflagellate cysts under controlled environmental conditions:
Cyst production and morphology is studied in relationship to changing environmental conditions
Seasonal production of dinoflagellate cysts in natural settings
The seasonal cyst production is being studied on sediment trap material collected off Cape Blanc (NW Africa).
Modern cyst distribution in relationship to environmental conditions in the upper water column
Although there generallities the reaction of cyst production of species can be different in different regions. As a result, for adequate use in palaeo-environmental, oceanographic and climatic studies a detailed tuning of the region specific cyst association to local environmental upper water conditions and bottom water oxygen concentrations is required.
