项目摘要

9623627 Lauder Natural selection is believed to maintain symmetry in vertebrate jaws because any deviation from symmetry would negatively affect the ability to acquire food. Yet, as adults, flatfish have morphologically asymmetrical jaws and might exhibit asymmetrical prey capture. This project will determine if and how functional asymmetry is produced in two flatfish species using high-speed video analysis, morphological description, electromyography, and three- dimensional modeling of jaw mechanisms. Preliminary results indicate that one flatfish species produces asymmetrical gape and bending of the jaws out of the midline during prey capture. However, another species does not experience jaw bending or asymmetrical gape. This project will focus on modifying current two-dimensional models to produce three- dimensional models which can accurately predict functional asymmetry. Models generated will be used in the future to predict prey capture behavior in other flatfishes and applied to symmetrical fishes to gain a better understanding of the three-dimensional nature of prey capture mechanisms. This project will add to our understanding of morphological diversity, and related diversity in the capture of prey, that can exist in an important group of organisms.

小行星9623627 自然选择被认为保持了脊椎动物颌骨的对称性，因为任何偏离对称性的行为都会对获取食物的能力产生负面影响。然而，作为成年人，比目鱼有形态不对称的下巴，可能会表现出不对称的猎物捕获。这个项目将确定功能不对称是否以及如何在两个比目鱼中产生物种使用高速视频分析，形态描述，肌电图，和钳口机构的三维建模。初步研究结果表明，一种比目鱼物种产生不对称的张开和弯曲的下巴在猎物捕获的中线。然而，另一个物种没有下颌弯曲或不对称的张口。本计画将致力于改良目前的二维模型，以产生能准确预测功能不对称的三维模型。所产生的模型将在未来用于预测猎物捕获行为在其他比目鱼和对称的鱼类，以获得更好地了解猎物捕获机制的三维性质。这个项目将增加我们对形态多样性的理解，以及捕获猎物的相关多样性，这些多样性可能存在于一个重要的生物群体中。
