由于人为气候变化，沿海生境正在经历海水pH值下降和温度上升。加勒比海帝王蟹(Maguimithrax Spinosis Simus)在西大西洋珊瑚礁上扮演着至关重要的角色，它以大型藻类为食，与新来的珊瑚争夺空间。因此，如果要考虑将该物种作为珊瑚礁环境中潜在的恢复管理策略，则迫切需要确定其对人为应激源的耐受性。在完全交叉的实验室实验中，我们研究了温度(对照：28℃，升高：31℃)和pH(对照：8.0，降低pH：7.7)对帝王蟹幼体和早期幼体存活、蜕皮期持续时间和形态的影响。与对照组相比，在降低pH和升高温度的联合处理中，巨噬细胞的存活率降低了13.5%。在降低pH的处理中，第一阶段(J1)幼蟹的蜕皮时间推迟了1.5天，而第二阶段(J2)的幼蟹在高温下提前了3天蜕皮。幼体形态在不同处理之间没有差异。这些结果表明，幼年帝王蟹对与气候变化相关的变化具有耐受性。鉴于帝王蟹作为大型藻类捕食者的重要作用，它对气候压力的耐受性表明，它可能有助于恢复努力，旨在使珊瑚礁在未来更能适应日益温暖和酸性的海洋。
Coastal habitats are experiencing decreases in seawater pH and increases in temperature due to anthropogenic climate change. The Caribbean king crab,Maguimithrax spinosissimus, plays a vital role on Western Atlantic reefs by grazing macroalgae that competes for space with coral recruits. Therefore, identifying its tolerance to anthropogenic stressors is critically needed if this species is to be considered as a potential restoration management strategy in coral reef environments. We examined the effects of temperature (control: 28 °C and elevated: 31 °C) and pH (control: 8.0 and reduced pH: 7.7) on the king crab’s larval and early juvenile survival, molt-stage duration, and morphology in a fully crossed laboratory experiment. Survival to the megalopal stage was reduced (13.5% lower) in the combined reduced pH and elevated temperature treatment relative to the control. First-stage (J1) juveniles delayed molting by 1.5 days in the reduced pH treatment, while second-stage (J2) crabs molted 3 days earlier when exposed to elevated temperature. Juvenile morphology did not differ among treatments. These results suggests that juvenile king crabs are tolerant to changes associated with climate change. Given the important role of the king crab as a grazer of macroalgae, its tolerance to climate stressors suggests that it could benefit restoration efforts aimed at making coral reefs more resilient to increasingly warm and acidic oceans into the future.
