Percentage polyp survival during salinity fluctuations (Experiment C).

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.

在"处理3"组中，受试水螅仅经历一次盐度由47降至35的变化；与之不同的是，前期实验首先设置了盐度从47变为40的"处理1"组，随后又开展了盐度从40变为35的"处理1,2"组。在"处理2"组中，受试水螅仅经历一次盐度由20升至35的变化。SD为标准差（standard deviation），n为重复实验次数，每个重复实验平均包含20个受试水螅。
