Nikola Medic:
Eco-physiology of ichthyotoxic constitutive mixoplankton

Mixotrophic protists with a constitutive capacity of mixotrophy are defined as constitutive mixoplankton (CM). They possess their own  chloroplast and are capable of food ingestion within a single cell. Some mixoplankton species produce lytic toxins; consequently, they have detrimental effects on the marine environment. In this thesis, I investigated the effect of irradiance levels, nutrient and prey concentrations on growth, photosynthesis, feeding and toxicity in two ichthyotoxic constitutive mixoplankton species, the haptophyte P. parvum and dinoflagellate K. armiger.
