The largest differences between taxa are due to the dinoflagellates, raphidophytes, and diazotrophs having lower α than the other taxa, which have comparable mean values for this trait (fig. The difference between taxa with the lowest (dinoflagellates) and highest (miscellaneous haptophytes) mean α is roughly a factor of 4 (fig.

Generally, when growing in presence of various different n compounds, dinoflagellates (as well as plants and algae) prefer to take up nh+4. However, there is a concentration threshold above which nh+4 becomes toxic to the cells[] cool fact. Another tendency in dinoflagellates is inhibition of no−3 uptake when in the presence of nh+4.

Those that produce toxins (poisons) or cause physical damage with sharp spines are members of groups called diatoms, dinoflagellates and raphidophytes. In the following sections we describe which phytoplankton on west coast of north america are harmful and how they cause harm to fish, marine mammals, and sometimes even humans.
Extracts of fifty-seven newly isolated strains of dinoflagellates and raphidophytes were screened for protein phosphatase (pp2a) inhibition. Five strains, identified by rdna sequence analysis as prorocentrum rhathymum, tested positive and the presence of okadaic acid was confirmed in one strain by hplc-ms/ms and by hplc with fluorescence detection and hplc-ms of the okadaic acid adam derivative.
