珊瑚的成功繁殖和存活对于珊瑚在全球范围内的延续和恢复至关重要。随着气候变化导致珊瑚礁水域变暖，周期性的大规模热带风暴正变得更加频繁，在短时间内极大地改变了近岸的水质。因此，我们必须了解海水变暖、淡水输入和径流对珊瑚有性繁殖的影响。为了更好地了解这些近岸应激源对夏威夷珊瑚的影响，海洋生物研究所进行了实验室实验，以确定悬浮泥沙浓度(100mgL−1和200mgL−1)、较低的盐度(28‰)和较高的温度(31℃)对头状单孢藻珊瑚的成功受精、幼体存活和定居的独立影响。在本研究中，将发育早期的珊瑚暴露于三种近岸应激源中的一种，持续24小时，并观察和测量了即刻(受精)和潜在的影响(幼体存活和定居)。任何一种处理都不影响受精成功率和定居，但所有处理对幼虫存活率的负面影响都在50%或更大(p>；0.05)。这些数据表明，与变暖和更频繁的风暴事件有关的近岸应激源可能会影响到头藻的早期生活期。
Successful reproduction and survival are crucial to the continuation and resilience of corals globally. As reef waters warm due to climate change, episodic largescale tropical storms are becoming more frequent, drastically altering the near shore water quality for short periods of time. Therefore, it is critical that we understand the effects warming waters, fresh water input, and run-off have on sexual reproduction of coral. To better understand the effects of these near shore stressors on Hawaiian coral, laboratory experiments were conducted at the Institute of Marine Biology to determine the independent effects of suspended sediment concentrations (100 mg l−1 and 200 mg l−1), lowered salinity (28‰), and elevated temperature (31 °C) on the successful fertilization, larval survival, and settlement of the scleractinian coral Montipora capitata. In the present study, early developmental stages of coral were exposed to one of three near shore stressors for a period of 24 h and the immediate (fertilization) and latent effects (larval survival and settlement) were observed and measured. Fertilization success and settlement were not affected by any of the treatments; however, larval survival was negatively affected by all of the treatments by 50% or greater (p > 0.05). These data show that early life stages of M. capitata may be impacted by near shore stressors associated with warming and more frequent storm events.
