The application of nuclear track autoradiography to the determination of inorganic carbon assimilation rates of fifteen periphytic algal species is described. Vertical profiles of carbon assimilation for each species following three periods of substrate colonization are presented, along with the contribution made by each species to total algal productivity. It is demonstrated that cellular carbon assimilation rates are a function of cell surface area and that, as a consequence, small periphytic algae have shorter generation times than large algae
