Zoanthus spp 的变化。 1980年5月至1982年10月期间，通过样线调查，在日本鹿儿岛樱岛大正熔岩场（N31°35’，E135°35’）进行了为期30个月的样线测量，记录了水螅体、水螅属性腺和虫黄藻数量在不同海水温度下的变化。我们的结果表明，藏花息肉在夏季和秋季生长，并在冬季和春季缩小。水螅体在冬季气温较低期间闭合，虫黄藻的活性和浓度也会降低，这可能是由于水螅体上方许多类型的藻类在冬季生长以及水螅体本身出现硅藻所致。此外，附近樱岛活火山锥产生的火山灰也对藏花珊瑚产生负面影响。
Changes in Zoanthus spp. cover and polyp number were recorded by transect survey at Taisho Lava Field, Sakurajima, Kagoshima, Japan (N31°35’, E135°35’) for 30 months between May 1980 to October 1982. In addition, lab experiments were conducted to investigate changes in polyps, Zoanthus’ gonads and zooxanthellae number at different seawater temperatures. Our results indicate that Zoanthus polyps grow during summer and autumn, and experience a decrease in size during winter and spring. Polyps close during periods with low winter temperatures, and zooxanthellae activity and concentration also decrease, perhaps due to the winter growth in many types of algae above polyps and the appearance of diatoms on polyps themselves. In addition, volcanic ash from the nearby active volcanic cone of Sakurajima also has a negative effect on Zoanthus polyps.
