Abstract Mycosporine-like amino acids (MAAs), which occur in diverse taxonomic groups, exhibit invivo absorption maxima between 310nm and 360nm and may play a photoprotective role against ultraviolet (UV) exposure. Using cultures of colonial Phaeocystis antarctica, we examined the relationship between MAA concentration, invivo UV absorption, photoprotective (carotenoid) and photosynthetic pigments,...
Using a short-term incubation technique for determining uptake cultures of Thalassiosira oceanica Skeletonema costatum, Emiliania huxleyi and Dunaliella tertiolecta were found to be capable of assimilating iodate at rates ranging from 0.003 to 0.24 nmol IO -3 μg chlorophyll a -1 h -1 . It is suggested that there is a steady state between iodate uptake and release...
