Blooms of the toxic dinoflagellate Ostreopsis cf. ovata are usually associated with shallow and calmcoastal waters, characterized by low nutrient concentrations. The algal cells typically cover the benthicsubstrates, such as the macroalgal and invertebrate communities and rocks, forming a mucilaginous film.

The obtained results strongly suggest that in the environment toxin production is steadily sustained by a low and constant nutrient supply, able to maintain appropriate cellular C:N (>12) or C:P (>170) ratios for a long period.

That’s just from the abstract….still need to digest the details on this one.
