Fig. 3. The effect of varying the duration of exposure to 25 mmol l-1 caffeine on release of symbiotic algae from Aiptasia pulchella. The control anemones (C) were held at 25°C, while the cold-shocked anemones (CS) were held at 12°C for 2.5 h. Cell release is expressed as a percentage of the total number of symbiotic dinoflagellates in the anemone [(released/released+retained)x100] released into the medium. Values are means + S.E.M., N=5 in each condition. *Significantly different from the control value, P
0.01.
