鹿角珊瑚（Acropora formosa）的枝尖暴露在高浓度的铜中，以检验“漂白”反应的潜力，作为评估珊瑚压力的一种手段。两个相同的毒性试验在48小时内使用2个自然密度不同的藻（虫黄藻）菌落进行。由于虫黄藻流失到周围的水中，两个群落的尖部与铜浓度成正比。在虫黄藻较少的群体中，观察到较高的死亡率。在测试中，对照珊瑚虫黄藻的流失速度为
Branch tips from colonies of a staghorn coral Acropora formosa were exposed to elevated concentrations of copper in order to examine the potential of the 'bleaching' response as a means of assessing stress in corals. Two identical toxicity tests were conducted over 48 h using 2 colonies with naturally different algal (zooxanthellae) densities. The tips from both colonies bleached in proportion to the copper concentrations, through loss of zooxanthellae to the surrounding water. A higher incidence of mortality was observed in tips from the colony with fewer zooxanthellae. During the tests, control corals lost zooxanthellae at a rate of
