珊瑚的温度耐受性。verrucosa（Lamarck）受盐度和光照的影响。低盐度降低了珊瑚在短期高温下生存的能力。高自然光强度减轻了珊瑚在高温下受到的伤害。在长期的生长实验中，高光强度造成大量的损失zooxanthellar色素，更高的死亡率，减少碳固定和降低生长速度在上和较低的亚致死温度。在最佳温度下的光的影响是不太戏剧性的。物理环境因素之间的相互作用似乎在给定因素的容许极限附近最重要。表明了适应能力，并受到受胁迫珊瑚的热历史和色素沉着状态的影响。
Temperature tolerance in the reef coral M. verrucosa (Lamarck) is affected by salinity and light. Low salinity reduces ability of the coral to survive short-term exposure to elevated temperature. High natural light intensity aggravates damage sustained by corals at high temperature. In long-term growth experiments, high light intensity caused substantial loss of zooxanthellar pigment, higher mortality rates, reduced carbon fixation and lowered growth rate at both upper and lower sublethal temperatures. Effects of light at optimal temperature were less dramatic. Interactions between physical environmental factors appear most important near the limits of tolerance for a given factor. Acclimation capability was indicated and was influenced by both thermal history and pigmentation state of stressed corals.
