SGER: Dynamics of Cnidarian Vascular Systems

众所周知，珊瑚对温度升高非常敏感，这种敏感性已经成为关于珊瑚礁系统对全球气候变化响应性的争论的框架。该项目将探索珊瑚维管系统动力学的各个方面，这是一个由珊瑚虫和匍匐茎或振荡体组成的相互连接的系统。巴斯假设珊瑚白化，最终死亡，是由血管系统大小的混乱变化造成的。为了探索这种可能性，Buss计划通过实验改变经匍匐茎的胃血管流动速度，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，将开发一个耦合振荡器的空间网格。该模型应基于对生物物质的扰动研究来预测珊瑚的行为动力学，并使人们更好地理解珊瑚采用特定结构形式的原因。

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.
