Divergent responses of an armored and an unarmored dinoflagellate to ocean acidification.

Dinoflagellates, both armored and unarmored, with distinct cell wall difference, are being affected by elevated CO-induced ocean acidification (OA). However, their specific responses to OA are not well understood. In this study, we investigated the physiological and molecular response of the armored species Prorocentrum obtusidens and the unarmored species Karenia mikimotoi to OA over a 28-day period.
