Abstract

Standard autoradiographic techniques have been used to describe the temporal pattern in the transfer of radioactive carbon from the chlorophyte Tetraselmis suesica (Kylin) to females of the neritic copepod Temora longicornis (Müller, 1792). After 4 and 6 h exposure to labelled phytoplankton, silver grains were deposited only in the cells of the gut-wall. After 24 h exposure, grains were deposited in most tissues, with highest concentrations in cells of the gut-wall and in oocytes within the ovary. Experiments with Centropages typicus (Krøyer), Centropages hamatus (Lilljeborg), and Labidocera aestiva Wheeler demonstrated that much of the assimilated label was not turning over rapidly and that the amount of label assimilated was correlated with known food preferences of these species.
