Plankton resting stages: ecological, evolutionary and geological perspectives

05.10 - 08.10.2015  
Hanko Peninsula, Finland


Life cycles of many plankton species involve a physiologically dormant resting stage, often in a form of
thick-walled, resistant cell or egg that differs morphologically from its motile, vegetative counterpart. Resting stage is a common trait for e.g., dinoflagellates, diatoms, cyanobacteria, cladocerans, rotifers and copepods.

Resting stages form seed banks that allow survival over adverse conditions and even cryptic persistence for decades.  The fact that plankton organisms may spend much longer time dormant than active has profound implications not only for the individual life cycle, but for population ecology and species evolution, and accordingly, for the way researchers need to consider and study plankton.


Plankton resting stages – geological, ecological and evolutionary perspectives brings together geologists, paleoecologists, ecologists and geneticists who approach plankton resting stages from diverging perspectives and ordinarily work in isolation from each other. The workshop aims at presenting the extent of research lines and bringing forward joint targets for development and interest.


The three topical sessions with invited keynote speakers:

Resting stages and geology: Long-term archives and indicators of change
Resting stages and ecology: Environmental cues and ecological significance
Resting stages and evolution: Living archives and evolutionary significance.

Furthermore, a discussion session and informal, social activities in the beautiful archipelago setting will be on the agenda.
