Corals are notoriously sensitive to elevated temperatures and this sensitivity has come to frame debates regarding the responsiveness of reef systems to global climate change. This project will explore aspects of the dynamics of the coral vascular system, an inter-connecting system of polyps and stolons or oscillators. Buss hypothesizes that coral bleaching, and ultimately mortality, results from the chaotic change in the size of the vascular system. To explore this possibility, Buss plans to alter the velocity of gastrovascular flow through stolons experimentally and to monitor radial diameter of stolons using sophisticated video and image analysis. Then, to visualize the chaotic behavior of the vascular system, a spatial grid of coupled oscillators will be developed. The model should predict the behavior dynamics of corals based on perturbation studies of living material and lead to a better understanding why corals adopt specific structural forms.

众所周知，珊瑚对高温非常敏感，这种敏感性引发了有关珊瑚礁系统对全球气候变化响应能力的争论。 该项目将探索珊瑚血管系统动力学的各个方面，珊瑚血管系统是息肉和匍匐茎或振荡器的互连系统。 巴斯假设珊瑚白化以及最终的死亡是由于血管系统大小的混乱变化造成的。 为了探索这种可能性，巴斯计划通过实验改变通过匍匐茎的胃肠血管流动速度，并使用复杂的视频和图像分析来监测匍匐茎的径向直径。 然后，为了可视化血管系统的混沌行为，将开发耦合振荡器的空间网格。 该模型应根据生物物质的扰动研究来预测珊瑚的行为动态，并有助于更好地理解为什么珊瑚采用特定的结构形式。
