Dissertation Research: The Evolutionary Morphology and Bio- mechanics of Tetraodontiform Fishes

Tetraodontiform鱼类包括一组不同的功能 类型，如河豚，箱鲀，巨大的海洋太阳鱼。 研究生伊丽莎白·布雷纳德提出了功能性和 生物力学性能测试的各种这些鱼类， 现场和实验室环境中。 将收集数据 使用高速录像和肌电图 （肌肉激活模式的记录），并将提供一个 更清楚地了解他们各自的防御效率， 运动和食物采集 获取的不同数据 鱼类物种将相对于它们的进化进行比较， 关系，以评估功能效率是否 在进化过程中增加或保持不变或减少。 该论文的研究是一个雄心勃勃的， 创新研究，将产生广泛感兴趣的数据， 鱼类学家 这项研究的概念含义是 广泛的，结果将是感兴趣的功能 形态学家和进化生物学家。

Tetraodontiform fishes comprise a varied group of functional types, such as puffer fishes, boxfishes, giant oceanic sunfish. Graduate student Elizabeth Brainerd proposes functional and biomechanical performance tests on a variety of these fishes in the field and in laboratory settings. Data will be gathered using high-speed video recordings and electromyography (recordings of muscle activation patterns), and will provide a clearer picture of their respective efficiencies in defense, locomotion, and food gathering. The data acquired for different fish species will be compared relative to their evolutionary relationships in order to assess whether functional efficiency has increased during evolution or remained static or decreased. The proposed dissertation research is an ambitious and innovative study that will produce data of wide interest to ichthyologists. The conceptual implications of the study are broad, and the results will be of interest to functional morphologists and evolutionary biologists in general.
