In the first experiment (Fig. 8A), hydroids collected at dusk and main- tained without food in either constant light or dark showed the same level and timing of MI as seen in hydroids in the field (Fig. 6). Thus it appears that altering food and the light and dark periods less than 12 h before the expected peak in MI does not influence the division patterns of the /ooxan- tltdlae. Hydroids that were collected from the field at the fiul of the dark period (when MI of symbionts was highest) and maintained in constant Hunt or in constant dark showed o LL o 4O 3O O 6?
