    Samenvatting

    Flagellates of Phaeocystis globosa were observed inside colonies in North Sea samples in 1992. Field data suggest that low phosphate concentrations (less than or equal to0.5 muM) and, as a consequence of sedimentation, a 20- to >100-fold reduction of daily irradiance (to m), (ii) the haploid mesoflagellate (4.2 +/- 0.1 mum), (iii) the diploid macroflagellate (6-7 mum) which is Kornmann's (Kornmann, 1955) 'Makrozoospore', and (iv) the diploid non-flagellate colonial cell (6.1 +/- 0.2 mum). A life cycle for Phaeocystis is presented, and the life-cycle transitions still to be tested are identified.
