The private life of Cystodinium: in situ observation of its attachments and population dynamics.

ABSTRACT: Phytoplankton images were collected using an Imaging Flow Cytobot moored in the mesotrophic lake Lac Montjoie (Quebec, Canada). Cystodinium-an unusual dinoflagellate genus-was found during manual classification of the images into taxonomic groups while building an automated classifier. Cystodinium's particularity is that while it can take a typical motile dinoflagellate form, it is thought to exist primarily as an immotile photosynthetically competent parasitic cyst in the shape of a crescent moon. Observations presented here are of this immotile lunate cyst. Manually classified images revealed that the majority of the Cystodinium found (86%) were attached to other microalgae or detrital material while the rest were unattached. The established auto-classifier was only
