Abstract

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.
