that dinoflagellates may utilize mimosine as a nitrogen source (Fig 3) The effects of mimosine on natural seawater samples probably resulted from both the selective growth of dinoflagel-lates and the selective death of other phytoplanktons, as there was an actual increase in the number of dinoflagellate cells during mimosine treatment
