ABR: Colony Integration in the Clonal Marine Benthos

巴斯9315082这一基于成就的奖项将允许巴斯博士继续致力于克隆海洋底栖动物的群体整合工作。近年来的主要目标是试图了解克隆生物生长形态和生活史之间相关性的因果基础。巴斯博士已经(1)证明了水样胃血管循环受息肉和匍匐茎空间分布的控制，前者充当泵，后者在息肉之间输送胃血管液体；(2)开发了能够自动收集胃血管动力学数据的技术；(3)证明了胃血管循环的扰动会在生长形态和生活史中产生可预测的变化。巴斯博士将开发一个计算机模型，该模型将预测模型群体的生长形态和生活史特征，并将在实验中验证该模型。与建立模式形成基因的表达是由流体动力信号的传导引起的工作一起，他将期望明确地建立生长形态和生活史之间关系的因果基础。****

Buss 9315082 This Accomplishment-Based Award will allow Dr. Buss to continue work on colony integration in the clonal marine benthos. The primary objective in recent years has been an attempt to understand the causal basis of the correlation between growth morphology and life history in clonal organisms. Dr. Buss has (1) demonstrated that hydroid gastrovascular circulation is controlled by the spatial distribution of polyps, which act as pumps, and stolons, which conduct gastrovascular fluid between polyps, (2) developed techniques that permit automated collection of data on gastrovascular dynamics and (3) demonstrated that perturbation of gastrovascular circulation generates predictable alterations in growth morphology and life history. Dr. Buss will develop a computer model that will predict the growth morphology and life history characteristics of model colonies and will validate this model experimentally. Together with work on establishing that expression of pattern-forming genes is elicited by transduction of hydrodynamic signals, he will expect to unambiguously establish the causal basis of the relationship between growth morphology and life history. ****
