Note
It has been proposed that translocation of photosynthate from dinoflagellate endosymbionts ("zooxanthellae") to their cnidarian hosts is inversely related to zooxanthellar nutrient status. We investigated this relationship in the zooxanthellate sea anemone Aiptasia pallida (Verrill). Zooxanthellar nutritional status was manipulated by either feeding or starving sea anemones, and the flux of 14C-labelled photosynthate was measured in the intact association (in hospite).
