Germination results of individually isolated
dinoflagellate cysts from dated sediment cores
obtained in Koljö Fjord on the west coast of Sweden
will be presented. More than 500 cysts were isolated,mainly of the species Lingulodinium polyedrum,
Pentapharsodinium dalei and Scrippsiella trochoidea.and .
The time-span studied covers approximately the last
100 years. Other species with intact cell contents
were also present in the sediment cores but were not
as viable down in the core as L. polyedrum, P. dalei
and S. trochoidea. Results will be presented on
changes in viability of the three species down-core as
well as effects of storage and isolation conditions on
germination success and DNA preservation.
Quantitative data on densities of viable
dinoflagellates and diatoms in the historical sediment
layers will be discussed.
