Table 2. Percentage polyp survival during salinity fluctuations (Experiment C).

Treatment	Salinity 1	Salinity 2	% Survival		SD	n
1	47	40	93	±	34	3
1.2	40	35	94	±	8	3
2	20	35	68	±	37	3
3	47	35	105	±	30	4

In “Treatment 3” polyps exclusively experienced one change of salinity from 47 to 35, while a previous test checked first a change from 47 to 40 (“Treatment 1”), followed by a change from 40 to 35 “Treatment 1,2”. In “Treatment 2” polyps experienced one change of salinity from 20 to 35. SD is the standard deviation. n is the number of replicates and in each replicate were on average 20 polyps.
