Bipolar distribution of the cyst-forming dinoflagellate Polarella glacialis
Morphological investigations of motile cells and cysts of a small dinoflagellate (strain CCMP 2088) isolated from Canadian Arctic waters were carried out under both light and scanning electron microscopy. This species strongly resembled Polarella glacialis (strain CCMP 1383), which up to now was kno...
