Abstract

Chlorophyll (alpha) -normalized photosynthetic parameters, e.g. the photosynthetic efficiency ((alpha) ^B), and the maximum photosynthetic rate (P^B_m), for natural phytoplankton communities exhibit extreme ranges of variation. Part of this variation is related to the species composition of the communities, another part has methodological causes, and a large part has physiological causes, i.e. manifestations of adaptational responses to variations in environmental factors. To exemplify species differences in Chl(alpha) -normalized photosynthetic parameters, the high parameter values for prymnesiophytes in contrast to diatoms are discussed. These are primarily due to the lower chlorophyll (alpha) :carbon (Chl(alpha) :C) ratios in prymnesiophytes and therefore do not indicate that prymnesiophytes are superior to diatoms in the harvesting of light.
