项目摘要

To explore the evolution of complex functional anatomical systems, the researchers will study the respiratory apparatus in a diverse group of bottom-dwelling fishes (sculpins and allies). They will develop a new phylogenetic tree of relationships among 27 representative cottoid species based on DNA sequence data from four nuclear genes. The researchers will use dissection and computed tomographic (CT) scans to study anatomy of the respiratory apparatus and reconstruct its patterns of evolution. Functional consequences of these evolutionary anatomical changes will be studied using (1) an easily modified robotic model to simulate different types of fish breathing; and (2) pressure recordings from five representative species to assess the predictive power of the robotic model.This research will contribute to the graduate education of doctoral candidate Stacy Farina. The robot will be used in a workshop for the Expanding Your Horizons conference at Cornell University, which provides STEM experiences for 7-9th grade girls. While the focus of this study is on sculpins and allies, variation in cottoid anatomy is such that findings will be broadly applicable to many other groups of fishes. This project will also contribute to the development of techniques for using robotic models to study evolution of complex biomechanical systems.

为了探索复杂的功能解剖系统的进化，研究人员将研究一组不同的底栖鱼类（杜父鱼和盟友）的呼吸装置。他们将根据四个核基因的DNA序列数据，在27个代表性的Cottoid物种之间建立一个新的系统发育树。研究人员将使用解剖和计算机断层扫描（CT）来研究呼吸器官的解剖结构，并重建其进化模式。这些进化解剖学变化的功能后果将使用（1）一个容易修改的机器人模型来模拟不同类型的鱼呼吸;和（2）来自五个代表性物种的压力记录来评估机器人模型的预测能力。这项研究将有助于博士生斯泰西法里纳的研究生教育。该机器人将用于康奈尔大学“拓展你的视野”会议的研讨会，该会议为7- 9年级的女孩提供STEM体验。虽然这项研究的重点是杜父鱼和盟友，在cottoid解剖的变化是这样的，研究结果将广泛适用于许多其他鱼类群体。该项目还将有助于开发使用机器人模型研究复杂生物力学系统进化的技术。
